Abstract
The invention provides a heat emission structure, which can be used in any environment and is composed of an inner cavity and an outer cavity connected together and provided with via holes with the environment. The invention uses an air flowing path, which makes the heating element use the way of natural convection when working, and the generated heat is conducted out through the heat exchange, thereby the device is always working in the normal temperature range. The invention has no requirement on the position and the space of the heating elements.
Description
Technical field
The present invention relates to a kind of radiator structure, particularly relate to a kind of radiator structure that can under situation sluggish in air circulation, use.
Background technology
Being in the main performance problem that the various devices of febrile state face dispels the heat exactly; Because heater members all has the maximum temperature rise problem in service behaviour requires; Therefore just be necessary for these devices and solve heat dissipation problem, and make it be in a state of temperature under the relative environmental condition all the time.
At present, device radiating mode commonly used mainly contains 2 kinds: 1) material through good heat-conductivity conducts the heat that heater members produces; 2) through the large tracts of land of fin and the contact-making surface of air, the heat that device is produced carries out heat release by cross-ventilated mode.Above-mentioned the 1st kind of mode adopts the metal material high to the heat absorption rate, increased the weight and the cost of product; Though the 2nd kind of mode can weight reduction and reduced cost, than higher, radiating efficiency is low under the situation of the air flue that do not dispel the heat to the requirement in the position of using and space.
Summary of the invention
Technical problem to be solved by this invention provides a kind of radiator structure, and this radiator structure can normally use in any environment.
The technical scheme that technical solution problem of the present invention is adopted is: radiator structure; Form by internal cavity and external cavity; Said internal cavity communicates with external cavity, and said internal cavity and external cavity have through hole with the external world respectively, and said internal cavity is provided with venthole and communicates with the external world; Said external cavity is provided with air admission hole and communicates with the external world, and the cross section of said air admission hole is greater than the cross section of venthole.
The invention has the beneficial effects as follows: the present invention has adopted a kind of flow passage of air; Adopt the mode of natural convection air when making heater members work; The heat that produces is gone out by air transmitted through thermal energy exchange, thereby device is operated in the normal temperature range always.The present invention does not require position and the space that heater members uses.
Description of drawings
Fig. 1 is the cutaway view of the front view of the embodiment of the invention 1.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the sketch map behind loam cake and the safety glass that goes out of Fig. 2.
The specific embodiment
Radiator structure of the present invention adopts compound cavity body structure, and this structure is made up of internal cavity and external cavity, and internal cavity is equipped with heater members and fin, and external cavity communicates with internal cavity, and two cavitys have through hole to external world.
Be installed on the heat that heater members when work of internal cavity produces; Pass on the fin that is in the same cavity through heat; The heatsink temperature of this moment raises; Make air gas absorb heat energy through surperficial exchange heat, variation has taken place in pressure and density after the gas in the container is heated, has broken gas is in the energy relative equilibrium when other energy of nothing state; Heat energy with the GAS ABSORPTION of fin contact portion in the internal cavity increases, and must discharge through the form of its external work done and kinetic energy.Can know through Engineering Thermodynamics; Be added in heat energy in the gas equal gas externally the mechanical power of doing, overcome merit that friction consumes and kinetic energy, potential energy and interiorly can increase sum; In the compound cavity body radiator structure of the present invention receive behind the heat absorption energy gas externally institute's mechanical power of doing and interior can increase certain; Air admission hole and venthole through fair-sized just can guarantee the maximization of gas kinetic energy and potential energy, and the friction work done minimizes, and air is flowed in radiator structure of the present invention; The final conversion that forms cross-ventilation realization energy, thus the heater members in the work is in the normal operating temperature range all the time.
Embodiment 1:LED underground lamp
Like Fig. 1, Fig. 2 and shown in Figure 3, to form by internal cavity 1 and external cavity 2, internal cavity 1 is equipped with led light source 3 and fin 4, and this led light source 3 is exactly a heater members, and external cavity 2 communicates with the bottom of internal cavity 1, and external cavity 2 adopts shell 10 to be isolated from the outside.Be provided with safety glass 5 in led light source 3 upper ends, be used for preventing suffering artificial damage in use, and be provided with loam cake 9 above that.Internal cavity 1 has venthole 6 to communicate with the external world, and external cavity 2 communicates with the external world through inlet channel 7 and air admission hole 8.
Above-mentioned venthole 6 and air admission hole 8 are provided with a plurality of, and the size in the cross section of air admission hole 8 should be greater than the cross section of venthole 6.
Above-mentioned safety glass 5 also can adopt other transparent material to process.
During the work of LED underground lamp, the heat that the led light source 3 in the internal cavity 1 produces is passed to fin 4 through heat; Fin 4 temperature raise, and make the air gas in the internal cavity 1 absorb heat energy through surperficial exchange heat, and intermolecular distance strengthened after gas was heated; Internal gas pressure strengthens, and hot-air acts on the air contact layer between venthole 6 and internal cavity 1 bottom and the external cavity 2 respectively, and the sectional area of venthole 6 is different with the sectional area between two cavitys; Heated air can only be broken through the less relatively hole of pressure in the cavity of relative closure, promptly break through venthole 6 and take heat energy out of cavity and be discharged in the outside air, and can hot-air not taken out of from air admission hole 8; After hot-air is discharged into the external world; Internal cavity 1 atmospheric density diminishes, and for reaching air pressure balance, air outside then enters into external cavity 2 through air admission hole 8; Because external cavity 2 communicates with internal cavity 1; Extraneous air can enter into internal cavity 1, thereby the relatively low air of temperature that gets into from the outside has kept the inside and outside air pressure balance, finally forms cross-ventilation because of conversion of heat into kinetic energy and potential energy; Realized the conversion of energy, thereby the LED underground lamp in the work is in the normal operating temperature range of setting all the time.
Embodiment 2: the built-in lighting lamp
