For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
As shown in fig. 1, a schematic structural diagram of a battery module 10 according to an embodiment of the present application is provided, where the battery module 10 includes a single battery 200 and a heating and cooling device 100, and the heating and cooling device 100 includes a liquid cooling flat tube 120 and a flat tube joint 110, and the liquid cooling flat tube 120 is wound on the single battery 200 and contacts with the single battery 200 to heat or dissipate heat of the single battery 200.
The liquid cooling flat tube 120 may be in direct contact with the unit cell 200 or may be in indirect contact with another substance capable of conducting heat so as to exchange heat.
Referring to fig. 2 and fig. 3 together, fig. 2 is a schematic structural diagram of a flat pipe joint 110 according to an embodiment of the present application, and fig. 3 is a schematic connecting diagram of the flat pipe joint 110 and the liquid cooling flat pipe 120 shown in fig. 2.
In this embodiment, the flat pipe joint 110 includes a liquid inlet pipe 111 and a flat flow guiding pipe 112, wherein one end of the flat flow guiding pipe 112 is communicated with the liquid inlet pipe 111, and the other end of the flat flow guiding pipe 112 is communicated with a flat liquid cooling pipe 120 included in the heating and liquid cooling device 100. The heating components are uniformly distributed in the flat guide tube 112, and a user can control the heating function of the heating components to be turned on or off. When the heating function of the heating assembly is turned on, the liquid flowing through the flat guide tube 112 can be uniformly heated.
At present, it is common to pass a cooling liquid through the liquid cooling flat tube 120 to perform liquid cooling, and pass a heating liquid through the liquid cooling flat tube 120 to perform heating, and this method requires switching the liquid passing through the liquid cooling flat tube 120 as needed, which is very inconvenient to operate. Through the design, the heating function of the heating component is only required to be started when the battery module 10 is required to be heated, and the heating function of the heating component is required to be closed when the battery module 10 is required to be cooled, so that the operation is very convenient.
Moreover, since the heating components are uniformly distributed in the flat flow guiding tube 112, the liquid potential entering from the liquid inlet is required to flow through the flat flow guiding tube 112, so that the liquid entering into the liquid inlet tube 111 can be uniformly heated, and the temperature of the liquid finally entering into the flat liquid cooling tube 120 is uniform, but not the local temperature is too high or too low, so that the influence of the temperature unevenness on the performance of the battery module 10 can be avoided.
In this embodiment, the heating elements may be uniformly arranged in different ways. Referring to fig. 2 and 4, a brief description will be first made of the specific structure of the flat tube joint 110. In this embodiment, the flat flow guiding tube 112 includes a first flat flow guiding tube 410 and a second flat flow guiding tube 420, one end of the first flat flow guiding tube 410 is communicated with the liquid inlet tube 111, the other end of the first flat flow guiding tube 410 is provided with a groove 411, and the second flat flow guiding tube 420 is disposed in the groove 411 and forms an interval matched with the thickness of the inner wall of the first flat flow guiding tube 410 and the liquid cooling tube 120.
Optionally, in this embodiment, gaps for filling the material are formed between the wall of the liquid cooling flat tube 120 and the wall of the first flow guiding flat tube 410, and between the wall of the liquid cooling flat tube 120 and the wall of the second flow guiding flat tube 420. In implementation, a filling material may be filled into the gap to fix the liquid cooling flat tube 120 and the first and second flow guiding flat tubes 410 and 420 relatively. The filling material may be engineering plastic, pouring sealant or other glue, which is not limited in this embodiment.
The pipe wall at the end of the liquid cooling flat pipe 120 connected to the flat pipe joint 110 is inserted into the space, so that the pipe wall is clamped between the pipe wall of the first flow guiding flat pipe 410 and the pipe wall of the second flow guiding flat pipe 420.
It should be noted that the second flat flow guiding tube 420 may not be completely accommodated in the recess 411, and one end of the second flat flow guiding tube 420 may be exposed outside the recess 411 (see fig. 2).
Referring to fig. 3-6, fig. 5 is a schematic cross-sectional view of fig. 3 along the direction I, and fig. 6 is an enlarged schematic view of the region II in fig. 5. Fig. 5 shows a, B, C, and C, wherein a is a wall of the first flat flow guiding tube 410, B is a wall of the second flat flow guiding tube 420 located in the groove 411, and C is a wall of the flat liquid cooling tube 120 inserted into the space.
Referring to fig. 4 again, the second flow guiding flat tube 420 is divided into a plurality of first flow channels 422 by a plurality of first baffles 421, wherein each first flow channel 422 includes an upper sidewall and a lower sidewall, the upper sidewalls of the plurality of first flow channels 422 form the upper sidewalls 423 of the second flow guiding flat tube 420, and the lower sidewalls of the plurality of first flow channels 422 form the lower sidewalls 424 of the second flow guiding flat tube 420.
Referring to fig. 5-7 in combination, the upper side wall and the lower side wall of each first flow channel 422 are respectively provided with a corresponding mounting groove 425, where the "corresponding" may be defined as: when the mounting grooves 425 on the upper and lower side walls of any one of the first flow channels 422 correspond to each other, one baffle plate may be inserted into the two mounting grooves 425 corresponding to each other at the same time. In this embodiment, the liquid cooling flat tubes 120 are separated into a plurality of second liquid flow channels 122 by a plurality of second baffles 121 (see fig. 3), and portions of the plurality of second baffles 121 located in the second flow guiding flat tubes 420 are respectively embedded in the corresponding mounting grooves 425.
In detail, each of the second baffles 121 is simultaneously inserted into the corresponding mounting groove 425 on the upper and lower sidewalls of one first flow channel 422 to divide the other first flow channel 422 except for the two first flow channels 422 at the end into two sub-channels.
For example, as shown in fig. 6, after the second barrier 121D is inserted into the two mounting grooves 425 corresponding to each other, one first flow channel 422 is divided into a sub-channel T1 and a sub-channel T2.
By embedding the second baffle 121 into the mounting groove 425, communication between the liquid cooling flat tube 120 and the flow guiding flat tube 112 is achieved.
Based on the above structure, in one example, the heating assembly may include heating wires 426, and the heating wires 426 are uniformly distributed in the wall of the second flat flow guiding tube 420. In detail, as shown in fig. 6 and 7, the heating wire 426 is provided to each of the upper and lower sidewalls of the first flow channel 422 and the first baffle 421 connected between the upper and lower sidewalls of the first flow channel 422, so that the cooling liquid can be heated regardless of the position of the second flow guiding flat tube 420, thereby making the temperature of the liquid finally reaching the liquid cooling flat tube 120 relatively uniform without excessively large temperature difference.
Further, in this embodiment, more than two (including two) heating wires 426 may be disposed in the upper side wall, the lower side wall and the first baffle 421 connected between the upper side wall and the lower side wall of each first flow channel 422, and the more than two heating wires 426 may be disposed at equal intervals, so that a better heating effect may be achieved.
In yet another example, the heating assembly may include a heating film that may wrap around an outer sidewall of the second flow conduit 420, the heating film being sandwiched between the outer sidewall of the second flow conduit 420 and a wall of the liquid cooled flat conduit 120 that extends into the space when the liquid cooled flat conduit 120 is inserted into the space. As shown in fig. 6, the heating film is located between B and C. In yet another example, the heating assembly may include both the heater wire 426 and the heater film described above, as this embodiment is not limited in this regard.
In this embodiment, the flat tube joint 110 may be made of various materials, such as plastic, metal, etc., and in this embodiment, a metal material is preferably used to achieve a better heat conduction effect.
To sum up, the flat tube joint 110, the heating and liquid cooling device 100 and the battery module 10 provided in the embodiments of the present application, the flat tube joint 110 includes a liquid inlet tube 111 and a flow guiding flat tube 112, one end of the flow guiding flat tube 112 is communicated with the liquid inlet tube 111, and the other end is communicated with a liquid cooling flat tube 120 included in the heating and liquid cooling device 100. A heating element is arranged in the flat flow guide tube 112, which serves to uniformly heat the liquid flowing through the flat flow guide tube 112 when the heating function is switched on. In this way, the heating function of the heating component can be turned off when heat dissipation through the heating liquid cooling device 100 is needed, and the heating function of the heating component is turned on when heating through the heating liquid cooling device 100 is needed, so that on one hand, the integration of the heating function and the heat dissipation function is realized, and on the other hand, the liquid flowing through the diversion flat pipe 112 can be uniformly heated.
