Description
Technical Field
The present disclosure relates to the field of electronic devices, and in particular, to a control method and an electronic device.
Background
Edge computing devices are exposed to very severe operating environment temperatures, such as workshops up to 80 ℃, outdoors down to-40 ℃ in northern winter, and therefore increasingly demanding wide temperature support. The conventional electronic equipment can only work under the environment of 0-35 ℃, power consumption is reduced when the temperature exceeds 35 ℃, and the conventional electronic equipment cannot work normally at all when the ambient temperature reaches 80 ℃.
At such high ambient temperature, the polar heat dissipation by the heat dissipation components such as the heat dissipation fan and the heat dissipation fins cannot meet the requirement of cooling the electronic components, and the cooling needs to be performed by a refrigerator such as a semiconductor Cooler (TEC). The control of the TEC itself is also a complicated problem, which may cause condensation and short circuit of the system. For example, when the ambient temperature is 80 ℃ and the relative humidity is 30%, 50% or 80%, the dew point temperature is 53 ℃, 64 ℃ and 75 ℃, respectively, and when the ambient temperature is 80 ℃, the cold end temperature of the TEC is about 40 ℃ and is far lower than the dew point temperature to ensure the normal operation of the elements in the system, and therefore dew condensation is inevitable.
There are three main methods for dealing with dew condensation: sealing, filling inert gas and pouring sealant. However, the wide temperature system has many I/O interfaces, which are often plugged and unplugged, and it is difficult to achieve complete system sealing. The inert gas filling or waterproof water absorption structure can only reduce the air humidity in the system in a short time, and the water cannot be prevented from entering the system after long-term use. No matter the structure is a sealing, drying or waterproof water absorption structure, the auxiliary effect can be achieved, and the problem of condensation cannot be fundamentally solved. The use of the pouring sealant can lead to the system being not maintainable, and if a problem occurs, the system can only be replaced and cannot be repaired.

The embodiment of the application provides a control method, which comprises the following steps:
determining a first temperature limit value inside the current electronic equipment and the real-time temperature of a cold end of a refrigerator; the refrigerator is used for cooling the electronic equipment through the cold end of the refrigerator, so that the temperature in the electronic equipment is kept in a second working temperature range under the condition that the current environment temperature is in a first working temperature range of the electronic equipment, and the second working temperature range is smaller than the first working temperature range; the first temperature limit value is an air temperature value of the electronic equipment in a water vapor saturation state under the current air pressure;

By adopting the control method, whether the cold end of the refrigerator meets the condensation condition is judged by determining the first temperature limit value inside the current electronic equipment and the real-time temperature of the cold end of the refrigerator and judging whether the numerical relation between the real-time temperature of the cold end of the refrigerator and the first temperature limit value meets the first condition, and under the condition of meeting the condensation condition, the real-time temperature of the cold end of the refrigerator is increased, so that the interior of the electronic equipment is ensured not to be condensed.
The steps and principles of the control method according to the embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.
The control method of the embodiment of the application is applied to control the electronic device in the wide temperature range, and the electronic device may be, for example, a server, a desktop computer, a notebook computer, or other types of electronic devices, which are not described in detail herein, but it should be understood that the electronic device is not limited to the above listed types.
The working component of the electronic equipment generally has a physically allowed working temperature range, and for widening the external environment temperature range which can be adapted to the electronic equipment, the refrigerator is arranged in the electronic equipment, and the cold end of the refrigerator cools the electronic equipment, so that the internal environment where the working component of the electronic equipment is located is cooled through the refrigerator within a wider external environment temperature range, and the working component can still normally work.
That is, in the case that the external environment temperature at which the electronic device is currently located is within a first operating temperature range, the internal environment temperature of the electronic device is kept within a second operating temperature range, where the first operating temperature range may be an operating temperature range of the external environment of the electronic device, the first operating temperature range may be, for example, -40 ℃ to 80 ℃, and the second operating temperature range may be an operating temperature range of the internal environment of the electronic device, the second operating temperature range may be, for example, 0 ℃ to 35 ℃.
When the electronic equipment is cooled through the refrigerator and the internal environment temperature of the electronic equipment reaches the dew point temperature, the condensation phenomenon can occur, water vapor is condensed into water, and the condensed water easily causes the short circuit of the electronic equipment. This requires that the cold end of the refrigerator be prevented from reaching the dew point temperature while the refrigerator is controlled to cool the electronic device, thereby preventing condensation.
Fig. 1 is a flowchart of a first embodiment of a control method according to an embodiment of the present application, and referring to fig. 1, the control method according to the embodiment of the present application may specifically include the following steps:
s1, a first temperature limit inside the current electronic device is determined, as well as a real-time temperature of the cold end of the refrigerator.
The first temperature limit is an air temperature value of the electronic device at the current air pressure in a state of water vapor saturation inside the electronic device, that is, a dew point temperature of an internal environment of the electronic device at the current air pressure.
In a specific implementation, as shown in fig. 2, in step S1, the determining the first temperature limit inside the electronic device may include:
s11, determining a first environmental parameter inside the electronic equipment at present, wherein the first environmental parameter at least comprises a first temperature and a first humidity inside the electronic equipment;
s12, a first temperature limit is determined based on the first temperature and the first humidity.
The dew point temperature is generally affected by the ambient temperature, humidity, and air pressure, so that the temperature, humidity, and air pressure of the internal environment of the electronic device can be determined, and the dew point temperature inside the electronic device can be calculated according to the temperature, humidity, and air pressure of the internal environment of the electronic device. Since the air pressure in a region is generally stable, the air pressure may adopt an empirical value, and in such a case, only the current temperature and humidity of the internal environment of the electronic device, that is, the first temperature and the first humidity may be detected; a first temperature limit is determined based on the first temperature, the first humidity, and the air pressure empirical value. This first temperature and first humidity accessible set up at the inside temperature-sensing ware and the humidity inductor real-time detection of electronic equipment, and this temperature-sensing ware and humidity inductor can be for the inductor that sets up to the control method that this application was implemented, also can utilize existing temperature-sensing ware and the humidity inductor of electronic equipment, so, only need to arrive appointed memory location and acquire the data that contain this first temperature and first humidity.
The air pressure empirical value may be a preset value when the electronic device leaves a factory, or may be an air pressure empirical value obtained at a current position of the electronic device. For example, the current position of the electronic device may be obtained and determined through a Beidou positioning system or a GPS positioning system, an air pressure empirical value obtaining request is sent to a server of a service provider according to the current position of the electronic device, an air pressure empirical value of the current position fed back by the server is received, and then the first temperature limit value is determined based on the air pressure empirical value, the first temperature and the first humidity.
In practice, various types of refrigerators can be used, such as air-cooled refrigerators, compression refrigerators, semiconductor refrigerators, or other types of refrigerators. The cold end of the refrigerator is the low-temperature end of the refrigerator, and taking a semiconductor refrigerator (TEC) as an example, the low-temperature surface of the TEC is the cold end thereof. Semiconductor refrigerators are usually equipped with sensors capable of detecting the temperature of their cold and hot ends, so that the temperature of their cold ends can be self-detected by the refrigerator in real time. Of course, in the case that the refrigerator itself is not equipped with an inductor capable of detecting the temperature of the cold end thereof, the external inductor may be used to detect the real-time temperature of the cold end of the refrigerator.
S2, performing an operation for increasing the real-time temperature of the cold end of the refrigerator in a case where the numerical relationship between the real-time temperature of the cold end of the refrigerator and the first temperature limit meets a first condition.
The first condition is a condition that the water vapor reaches the cold end of the refrigerator to form dew condensation, namely, a condition that the water vapor contacting the cold end of the refrigerator or the water vapor close to the cold end of the refrigerator is condensed into water when the real-time temperature of the cold end of the refrigerator is close to, reaches or is lower than the dew point temperature. In practice, this first condition is a condition on the numerical relationship between the real-time temperature and the dew point temperature of the cold end of the refrigerator. Under the condition that the numerical relation between the real-time temperature of the cold end of the refrigerator and the first temperature limit value accords with the first condition, determining that the water vapor in contact with the cold end of the refrigerator or the water vapor close to the cold end of the refrigerator has the risk of condensation, executing the operation capable of improving the real-time temperature of the cold end of the refrigerator, and accordingly avoiding forming condensate water, further avoiding short circuit of a circuit of the electronic equipment and ensuring stable operation of the electronic equipment.
In order to further reduce the risk of condensation, a safety temperature range can be configured on the basis of the dew point temperature, so that a first threshold value is formed, and whether the cold end of the refrigerator has the risk of condensation is determined by judging whether the difference value between the real-time temperature of the cold end of the refrigerator and the first temperature limit value is smaller than the first threshold value. Under the condition that the difference value between the real-time temperature of the cold end of the refrigerator and the first temperature limit value is smaller than the first threshold value, the cold end of the refrigerator is determined to have a condensation risk, and the operation for improving the real-time temperature of the cold end of the refrigerator is executed to avoid the condensation phenomenon. Therefore, the internal environment of the electronic equipment can be better prevented from dewing.
In effect, the dew point temperature of the internal environment of the electronic device is determined based on the real-time temperature and humidity of the internal environment of the electronic device, and the lower limit of the second operating temperature range is redefined based on the configured safe temperature range, thereby forming a third operating temperature range. The third operating temperature range is an operating temperature range in which the temperature of the internal environment of the electronic device physically allows the operating components to operate normally, and condensation in the internal environment of the electronic device can be avoided. Theoretically, the lowest temperature position in the internal environment of the electronic device should be the cold end of the refrigerator, so that as long as the real-time temperature of the cold end of the refrigerator is lower than the lower limit value of the third working temperature range, the internal environment of the electronic device is represented to be likely to generate a condensation phenomenon, at least the cold end of the refrigerator is likely to generate condensation, and the operation of improving the cold end of the refrigerator can be executed to avoid the condensation.
According to the control method, the first temperature limit value inside the current electronic equipment and the real-time temperature of the cold end of the refrigerator are determined, whether the cold end of the refrigerator meets the condensation condition is judged by judging whether the numerical relation between the real-time temperature of the cold end of the refrigerator and the first temperature limit value meets the first condition, and under the condition that the condensation condition is met, the real-time temperature of the cold end of the refrigerator is increased, and the fact that condensation does not exist inside the electronic equipment is ensured. Like this, for preventing the internal environment of electronic equipment from appearing the dewfall from operating mode control angle and providing effectual solution, be of value to reducing the configuration requirement of electronic equipment to structures such as sealed, dry, waterproof and water absorption, when improving electronic equipment security and stability, be of value to reducing electronic equipment's manufacturing cost.
In particular implementations, the increasing the real-time temperature of the cold end of the refrigerator may be performed in a number of ways, and in one particular embodiment, performing the operation for increasing the real-time temperature of the cold end of the refrigerator may include:
a first operation for reducing a heat dissipation amount of a heat sink connected to a hot side of a refrigerator is performed to reduce a heat transfer speed from a cold side of the refrigerator to the hot side of the refrigerator, increasing a real-time temperature of the cold side of the refrigerator.
The hot end of the refrigerator can be the high-temperature end of the refrigerator or the end of the refrigerator used for radiating, the real-time temperature of the cold end is reduced by radiating heat through the hot end when the refrigerator works, the real-time radiating power of the radiator is reduced by executing the first operation, and the real-time temperature of the cold end of the refrigerator can be improved. Taking the TEC as an example, the TEC generally includes a cold surface and a hot surface, heat flows from the cold surface to the hot surface during operation, the hot surface of the TEC is generally provided with a heat sink, the heat sink performs heat dissipation processing on the hot surface of the TEC, and a first operation is executed to reduce the heat dissipation capacity of the heat sink, so that the heat transmission speed from the cold surface to the hot surface of the TEC can be reduced, and the real-time temperature of the cold surface of the TEC can be further improved. According to different heat dissipation modes of the heat sink, the specific operation mode of the first operation can be different, when the heat dissipation fan is used as the heat sink, the first operation can be the operation of controlling the rotation speed of the heat dissipation fan to be reduced, when the cooling liquid is used for dissipating heat of the hot end of the refrigerator, the first operation can be the operation of controlling the flow rate of the cooling liquid to be reduced by the liquid delivery pump, of course, when other types of heat sinks are used, the first operation can also be in other specific operation modes, but only the real-time heat dissipation power of the heat sink can be reduced.
In another particular embodiment, performing an operation for increasing the real-time temperature of the cold end of the refrigerator may include:
a second operation for reducing the cooling power of the refrigerator is performed to increase the real-time temperature of the cold end of the refrigerator.
The refrigerating power of the refrigerator is reduced, the refrigerating capacity which can be provided by the refrigerator can be reduced, and the real-time temperature of the cold end of the refrigerator is inevitably increased under the condition of the same heating capacity of the electronic equipment, so that the condensation phenomenon of the cold end of the refrigerator is avoided. Taking the TEC as an example, the cooling power of the TEC can be reduced by adjusting an operating parameter such as an operating current or an operating voltage. Taking a compression type refrigerator as an example, the power of an air pressure pump for compressing the refrigerant can be reduced to reduce the refrigeration power of the compression type refrigerator.
In yet another particular embodiment, performing operations for increasing the real-time temperature of the cold end of the refrigerator may include:
and executing a third operation for reducing the power consumption of the electronic equipment to reduce the heat dissipation requirement of the electronic equipment, so as to reduce the real-time refrigerating power of the refrigerator.
The heat dissipation control system of the electronic equipment can regulate and control the real-time refrigeration power of the refrigerator based on the real-time power consumption of the electronic equipment, so that the energy consumption is reduced and the cold energy waste is avoided under the condition of meeting the heat dissipation requirement. The real-time power consumption of the electronic equipment is reduced, the heat productivity of the electronic equipment can be reduced, the heat dissipation requirement can be reduced, the heat dissipation control system can control the refrigerator to reduce the real-time refrigeration power based on the real-time power consumption of the electronic equipment, and therefore the real-time temperature of the cold end of the refrigerator is reduced.
Taking the electronic device as an example of a computer, main heat generating components of the computer are a central processing unit and a graphics processor, and when a first condition is triggered, the real-time power consumption of the central processing unit and/or the graphics processor can be reduced by means of, for example, frequency reduction or occupancy rate reduction, so that the heat dissipation control system of the computer reduces the real-time refrigeration power of the refrigerator based on the reduced real-time power consumption. When the electronic equipment is other types of equipment, the power consumption of the electronic equipment is reduced by adopting other modes, as long as the real-time refrigerating power of the refrigerator can be reduced by triggering the self heat dissipation control system to adapt.
The first operation to reduce the amount of heat dissipated by the heat sink is actually an operation taken to the end of the heat dissipation system, and the first operation has minimal impact on the normal use of the electronic device by the user. The second operation of reducing the cooling power of the refrigerator is actually an operation taken for an intermediate link of the cooling system, and the normal operation of the electronic device is indirectly influenced in a certain procedure. The third operation of reducing the power consumption of the electronic apparatus is an operation performed for the heat source, which can solve the problem of dew condensation from the source, but has the greatest influence on the normal use behavior of the user with respect to the first operation and the second operation, and the processing capability of the electronic apparatus is significantly reduced.
On this basis, the first operation, the second operation, and the third operation may be configured to have priorities in accordance with the operation modes of the first operation, the second operation, and the third operation, the capability of solving the dew condensation problem, and the influence on the user, and the priorities of the first operation, the second operation, and the third operation are sequentially lowered.
And, in the event that the numerical relationship between the real-time temperature of the cold end of the chiller and the first temperature limit satisfies a first condition, performing the first operation, the second operation, and/or the third operation based on the priority order to increase the real-time temperature of the cold end of the chiller.
Referring to fig. 3, for an electronic device using a TEC as an example, a first temperature and a first humidity of an internal environment of the electronic device and a real-time temperature of a cold side of the TEC may be monitored; a dew point temperature of an internal environment of the electronic device is determined based on the first temperature, the first humidity, and the barometric pressure empirical value. Determining a difference value between the real-time temperature and the dew point temperature of the cold surface of the TEC, judging whether the difference value delta T is larger than a first threshold value Ts, if the difference value delta T is larger than or equal to the Ts, controlling the electronic equipment to normally operate, circularly monitoring the first temperature, the first humidity and the real-time temperature of the cold surface of the TEC, and if the difference value delta T is smaller than the Ts, executing a first operation, reducing the rotating speed of a heat dissipation fan arranged on the hot surface of the TEC, reducing the heat dissipation capacity of the heat dissipation fan and further reducing the real-time temperature of the cold surface of the TEC.
And continuously monitoring the first temperature, the first humidity and the real-time temperature of the cold surface of the TEC, judging whether the updated delta T is more than or equal to Ts, if the delta T is more than or equal to the Ts, controlling the electronic equipment to normally operate, circularly monitoring the first temperature, the first humidity and the real-time temperature of the cold surface of the TEC, and if the delta T is less than the Ts, executing a second operation, and further reducing the refrigerating power of the TEC on the basis of reducing the rotating speed of a heat dissipation fan so as to reduce the real-time temperature of the cold surface of the TEC.
And continuously detecting the first temperature, the first humidity and the real-time temperature of the cold surface of the TEC, judging whether the updated delta T is more than or equal to Ts, if the delta T is more than or equal to the Ts, controlling the electronic equipment to normally operate, circularly monitoring the first temperature, the first humidity and the real-time temperature of the cold surface of the TEC, and if the delta T is less than the Ts, executing a third operation, and further reducing the power consumption of the processor on the basis of reducing the rotating speed of a heat dissipation fan and the refrigerating power of the TEC so as to reduce the real-time temperature of the cold surface of the TEC.
And continuously detecting the first temperature, the first humidity and the real-time temperature of the cold surface of the TEC, judging whether the updated delta T is more than or equal to Ts, if the delta T is more than or equal to the Ts, controlling the electronic equipment to normally operate, circularly monitoring the first temperature, the first humidity and the real-time temperature of the cold surface of the TEC, and if the delta T is less than the Ts, indicating that the environmental temperature is higher or the humidity is higher and exceeds the self-regulation capability of the electronic equipment, the condensation risk cannot be avoided, closing the electronic equipment and avoiding the circuit short circuit. That is, the electronics are shut down in the event that the third operation is performed to completion and the numerical relationship between the real-time temperature of the cold end of the refrigerator and the first temperature limit still meets the first condition.
It should be noted that, in the case that it is determined that the cold end of the refrigerator has the risk of dew condensation, on the basis of performing the first operation, the second operation and/or the third operation, it may further be determined whether the first humidity is greater than a humidity threshold, which may be, for example, 70%, if the first humidity is greater than the humidity threshold, it is indicated that the greater humidity in the internal environment of the electronic device is a cause of the higher dew-point temperature, and on the basis of performing the first operation, the second operation and/or the third operation, a dehumidification operation may be performed on the internal environment of the electronic device to reduce the value of the first humidity in order to reduce the dew-point temperature, so as to increase Δ T, so that Δ T is greater than or equal to Ts.
Continuing with FIG. 3, in some embodiments, the method further comprises:
detecting a second temperature and a second humidity outside the electronic equipment in real time when the electronic equipment is in an open state;
judging whether the second temperature is out of the first working temperature range and judging whether the second humidity is out of the first working humidity range,
and if the second temperature is out of the first working temperature range or the second humidity is out of the first working humidity range, the electronic equipment is turned off.
That is, in the operation process of the electronic device, monitoring the temperature and humidity of the external environment where the electronic device is located is implemented, and if the temperature of the external environment of the electronic device is higher than or lower than the first operating temperature range or the humidity of the external environment is higher than the first operating humidity range, it indicates that the external environment exceeds the bearing capacity of the electronic device, the electronic device cannot normally operate, and the electronic device is turned off in order to avoid irreversible damage to the electronic device.
As shown in fig. 4, in some embodiments, the method further comprises:
