[0027] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-7 The battery device 100 according to an embodiment of the present utility model is described. The battery device 100 includes: a connector 10, a heat exchanger 20, and an adapter 30.

[0028] Specifically, such as Figures 1-4 As shown, connector 10 is used to communicate with an external medium source; heat exchanger 20 is provided with heat exchange channel 26 and adapter 21 communicating with heat exchange channel 26; adapter 30 is detachably connected to connector 10 and adapter 21.

[0029] In this embodiment, the battery device 100 can be a battery pack or a car chassis, etc., and the external medium source can be a vehicle cooling system, etc. The adapter 30 is detachably connected to the connector 10 and the adapter 21, and the connector 10 and the adapter 21 are connected through the adapter 30. The external medium source is suitable for providing heat exchange fluid to the connector 10. The heat exchange fluid can enter and exit the heat exchange channel 26 of the heat exchange element 20 through the connector 10, the adapter 30 and the adapter 21, so as to realize the heat exchange between the heat exchange fluid and the heat exchange element 20 and achieve the cooling of the battery device 100. The heat exchange fluid supplied by the external medium source flows sequentially into the heat exchange channel 26 of the heat exchanger 20 through the connector 10, adapter 30, and adapter 21. Within the heat exchange channel 26, the heat exchange fluid exchanges heat with other heat-generating structural components within the battery device 100, and then sequentially flows out of the battery device 100 from the heat exchange channel 26, adapter 21, adapter 30, and connector 10. This cycle repeats, thereby achieving thermal management of the battery device 100. Optionally, the heat exchanger 20 is a cold plate, the heat exchange fluid is a refrigerant, and sealing structures are provided at the corresponding positions where the connector 10 and adapter 21 connect to the adapter 30 to improve the sealing and reliability of the connection.

[0030] According to the battery device 100 of this embodiment, the connection method between the connector 10 and the heat exchange component 20 is optimized. The connector 10, the adapter 21, and the adapter 30 jointly share the flow rate and pressure of the heat exchange fluid entering and leaving the battery device 100, ensuring stability and reliability during the heat exchange process. The adapter 30 facilitates adjustment of the assembly relationship between the connector 10 and the adapter 21, making replacement easier and reducing the maintenance difficulty of the battery device 100. Furthermore, the detachable design of the adapter 30 improves the assembly efficiency of the battery device 100.

[0031] Optionally, the heat exchanger 20 and the adapter 30 are made of aluminum alloy.

[0032] According to some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the connector 10 has a first adapter portion 12, and the adapter 21 has a second adapter portion 22. The first adapter portion 12 and the second adapter portion 22 are opposite to each other along a first direction A. The adapter 30 includes a first adapter 31, which connects the first adapter portion 12 and the second adapter portion 22. The first direction A is the length direction of the battery device 100, and the second direction B is the width direction of the battery device 100.

[0033] The connector 10 has a first adapter 12 at one end along the second direction B, and the adapter 21 has a second adapter 22 at one end along the second direction B. The first adapter 12 and the second adapter 22 are arranged in contact or spaced apart on the side adjacent to each other along the first direction A. The first adapter 31 is arranged along the first direction A, and the two ends of the first adapter 31 along the first direction A are respectively connected to the first adapter 12 and the second adapter 22. The heat exchange fluid provided by the external medium source flows from the connector 10 to the first adapter 12, the first adapter 31, the second adapter 22 and the heat exchange channel 26 of the heat exchanger 20 in sequence.

[0034] Therefore, by having the first adapter 12 and the second adapter 22 face each other along the first direction A, it is possible to avoid the first adapter 12 and the second adapter 22 occupying too much space in the battery device 100 along the second direction B, avoid interference between the second adapter 22 and other structural components arranged in the battery device 100 along the second direction B, increase the space utilization rate in the first direction A, improve the reliability of the arrangement of the first adapter 12 and the second adapter 22, and at the same time shorten the length of the first adapter 31 and reduce costs.

[0035] Furthermore, the first adapter 31 in this application is arranged along the first direction A, which can increase the utilization of the space around the heat exchanger 20, adapt to the arrangement of the heat exchanger 20 in the battery device 100, and improve the compactness of the internal space of the battery device 100.

[0036] Optionally, such as Figure 2 As shown, the connector 10 is provided with a third adapter 13, and the adapter 21 is provided with a fourth adapter 23. The third adapter 13 and the fourth adapter 23 are opposite to each other along the second direction B. The adapter 30 includes a second adapter 32, which connects the third adapter 13 and the fourth adapter 23.

[0037] The connector 10 is provided with a third adapter 13 at the other end along the second direction B, and the adapter 21 is provided with a fourth adapter 23 at the other end along the second direction B. The third adapter 13 and the fourth adapter 23 abut against each other on the side adjacent to each other along the second direction B. The second adapter 32 is provided along the second direction B, and the two ends of the second adapter 32 along the second direction B are respectively connected to the third adapter 13 and the fourth adapter 23. After heat exchange, the heat exchange fluid flows out from the heat exchange channel 26 of the heat exchanger 20 and flows sequentially to the fourth adapter 23, the second adapter 32, and the third adapter 13, and then flows out from the connector 10.

[0038] Therefore, by having the third adapter 13 and the fourth adapter 23 face each other along the second direction B, the space between the first adapter 12 and the third adapter 13 along the second direction B can be fully utilized, improving the compactness of the arrangement between the connector 10 and the adapter 21, and reducing the space occupied by the connector 10 and the adapter 21 in the internal space of the battery device 100.

[0039] In this application, the connector 10 is provided with a first adapter portion 12, the adapter 21 is provided with a second adapter portion 22, the connector 10 is provided with a third adapter portion 13, and the adapter 21 is provided with a fourth adapter portion 23. The first adapter portion 12 and the second adapter portion 22 are opposite to each other along a first direction A, while the third adapter portion 13 and the fourth adapter portion 23 are opposite to each other along a second direction B, which provides a limiting and guiding function for the assembly of the connector 10 and the adapter 21, thereby improving assembly efficiency.

[0040] According to some embodiments of this utility model, such as Figure 2 and Figure 6 As shown, the first adapter 31 is connected to one side of the first adapter portion 12 and the second adapter portion 22 along the third direction C. The third direction C intersects with both the second direction B and the first direction A. In this application, the third direction C is the thickness direction of the battery device 100, and the first direction A, the second direction B, and the third direction C are perpendicular to each other. The first adapter 31 is located on the same side of the first adapter portion 12 and the second adapter portion 22 along the third direction C and is connected to the first adapter portion 12 and the second adapter portion 22. Thus, the space within the battery device 100 along the third direction C can be fully utilized, and interference between the first adapter 31 and other structural components within the battery device 100 along the first direction A or the second direction B can be avoided.

[0041] Optionally, the second adapter 32 is connected to the third adapter 13 and the fourth adapter 23 on the same side along the third direction C. The second adapter 32 is located on the same side of the third adapter 13 and the fourth adapter 23 along the third direction C and is connected to the third adapter 13 and the fourth adapter 23. This allows for full utilization of the space within the battery device 100 along the third direction C, and avoids interference between the second adapter 32 and other structural components within the battery device 100 along the first direction A or the second direction B.

[0042] In this application, the first adapter 31 is connected to the side of the first adapter portion 12 and the second adapter portion 22 along the third direction C adjacent to the heat exchanger 20. Simultaneously, the second adapter 32 is connected to the side of the third adapter portion 13 and the fourth adapter portion 23 along the third direction C adjacent to the heat exchanger 20. That is, the first adapter 31 and the second adapter 32 are respectively connected to the connector 10 and the adapter 21 along the third direction C on the side of the connector 10 and the adapter 21 adjacent to the heat exchanger 20.

[0043] The connector 10 and adapter 21 provide positioning and limiting functions for the installation of the internal structure of the battery device 100, optimize the assembly accuracy of the internal structure of the battery device 100, and improve the efficiency and reliability of assembly.

[0044] According to some embodiments of this utility model, such as Figure 4 As shown, the first adapter 12 has a first mounting surface 121 that mates with the first adapter 31, and the second adapter 22 has a second mounting surface 221 that mates with the first adapter 31. The first mounting surface 121 and the second mounting surface 221 are flush.

[0045] The surface of the first adapter 12 adjacent to the heat exchanger 20 along the third direction C is the first mounting surface 121, and the surface of the second adapter 22 adjacent to the heat exchanger 20 along the third direction C is the second mounting surface 221. The first mounting surface 121 and the second mounting surface 221 are flush along the third direction C. Therefore, by designing the first mounting surface 121 and the second mounting surface 221 to be flush, the first adapter 31 can easily mate with the first mounting surface 121 and the second mounting surface 221 respectively, improving installation efficiency. At the same time, it improves the fit between the first adapter 31 and the first mounting surface 121 and the second mounting surface 221, thereby improving the reliability and stability of the installation of the first adapter 31.

[0046] Optionally, the third adapter 13 has a third mounting surface 131 that mates with the second adapter 32, and the fourth adapter 23 has a fourth mounting surface 231 that mates with the second adapter 32, with the third mounting surface 131 and the fourth mounting surface 231 being flush.

[0047] The surface of the third adapter 13 adjacent to the heat exchanger 20 along the third direction C is the third mounting surface 131, and the surface of the fourth adapter 23 adjacent to the heat exchanger 20 along the third direction C is the fourth mounting surface 231. The third mounting surface 131 and the fourth mounting surface 231 are flush along the third direction C. Therefore, by making the third mounting surface 131 and the fourth mounting surface 231 flush, the second adapter 32 can easily mate with the third mounting surface 131 and the fourth mounting surface 231 respectively, improving installation efficiency. At the same time, it improves the fit between the second adapter 32 and the third mounting surface 131 and the fourth mounting surface 231, thus improving the reliability and stability of the second adapter 32 installation.

[0048] In this application, the first mounting surface 121 is flush with the second mounting surface 221, and the third mounting surface 131 is flush with the fourth mounting surface 231. The placement of the connector 10 and the adapter 21 is optimized to avoid occupying the space of the battery device 100 along the third direction C, thus ensuring the reliability of the connection between the adapter 30 and the connector 10 and the adapter 21.

[0049] According to some embodiments of this utility model, such as Figure 4As shown, the connector 10 includes a first assembly part 17 and a second assembly part 18. The first assembly part 17 includes a first adapter part 12 and a third adapter part 13 disposed at both ends of the first assembly part 17 along the second direction B. The second assembly part 18 is connected to the first assembly part 17 and has an external medium source inlet 181 and an external medium source outlet 182. The external medium source inlet 181 is connected to the first adapter part 12 and the external medium source outlet 182 is connected to the third adapter part 13.

[0050] The heat exchange fluid provided by the external medium source flows sequentially from the external medium source inlet 181 of the second assembly part 18 to the first transfer part 12, the first transfer joint 31, the second transfer part 22 and the heat exchange channel 26 of the heat exchange component 20. After heat exchange, the heat exchange fluid flows out from the heat exchange channel 26 of the heat exchange component 20 and flows sequentially to the fourth transfer part 23, the second transfer joint 32 and the third transfer part 13, and flows out from the external medium source outlet 182 of the second assembly part 18.

[0051] Thus, through the design of the first assembly part 17 and the second assembly part 18, it is convenient for the heat exchange fluid provided by the external medium source to flow into and out of the connector 10, providing a complete heat exchange circuit inside the battery device 100. At the same time, by integrating the first adapter part 12 and the third adapter part 13 together on the first assembly part 17, and integrating the external medium source inlet 181 and the external medium source outlet 182 together on the second assembly part 18, the integration and compactness of the connector 10 can be improved.

[0052] According to some embodiments of this utility model, such as Figure 2 As shown, the first adapter 31 is connected to the first adapter portion 12 and the second adapter portion 22 via a first locking device 40. The first locking device 40 can be a bolt, a snap-fit, or other locking device. Therefore, by providing the first locking device 40, the connection strength and reliability between the first adapter 31 and the first adapter portion 12 and the second adapter portion 22 are improved.

[0053] Optionally, the second adapter 32 is connected to the third adapter 13 and the fourth adapter 23 respectively via a second locking device 41. The second locking device 41 can be a bolt, a snap-fit, or other locking device. Therefore, by providing the second locking device 41, the connection strength and reliability between the second adapter 32 and the third adapter 13 and the fourth adapter 23 are improved.

[0054] In this application, the first adapter 31 is connected to the first adapter part 12 and the second adapter part 22 respectively through the first locking device 40. At the same time, the second adapter 32 is connected to the third adapter part 13 and the fourth adapter part 23 respectively through the second locking device 41, thereby further improving the connection strength and reliability between the adapter 30 and the connector 10 and the adapter part 21, facilitating later maintenance and disassembly, and reducing maintenance and use costs.

[0055] According to some embodiments of this utility model, such as Figure 2 As shown, when the adapter 30 includes a first adapter 31 and a second adapter 32, the length of the first adapter 31 is less than the length of the second adapter 32. The first adapter 31 is located near the external medium source inlet 181 of the connector 10, and the second adapter 32 is located near the external medium source outlet 182 of the connector 10. Therefore, by making the length of the first adapter 31 less than the length of the second adapter 32, it is easier to distinguish between the first adapter 31 and the second adapter 32, thus preventing mistaken identification. Simultaneously, it facilitates the efficient use of space within the battery device 100 and avoids interference with other structures within the battery device 100.

[0056] According to some embodiments of the present invention, when the adapter 30 includes a first adapter 31 and a second adapter 32, the heat exchanger 20 has an inlet and an outlet, the flow rate of the inlet is greater than the flow rate of the outlet, the first adapter 31 is an inlet adapter, the second adapter 32 is an outlet adapter, and the number of first seals between the first adapter 31 and the first adapter portion 12 and the second adapter portion 22 is greater than the number of second seals between the second adapter 32 and the third adapter portion 13 and the fourth adapter portion 23.

[0057] The heat exchange fluid supplied by the external medium source flows sequentially from the external medium source inlet 181 of the connector 10 to the first transition section 12, the first transition joint 31, and the second transition section 22. It then flows from the inlet of the heat exchange element 20 into the heat exchange channel 26. The resistance of the heat exchange channel 26 to the heat exchange fluid increases. After heat exchange, the fluid flows out from the outlet of the heat exchange element 20 and sequentially flows to the fourth transition section 23, the second transition joint 32, and the third transition section 13. Finally, it flows out from the external medium source outlet 182 of the connector 10. The sealing structure includes a first seal and a second seal. The first seal is located between the first transition joint 31 and the first transition section 12 and the second transition section 22, and the second seal is located between the second transition joint 32 and the third transition section 13 and the fourth transition section 23. In this application, the number of first seals between the first adapter 31 and the first adapter 12 and the second adapter 22 is two, and the number of second seals between the second adapter 32 and the third adapter 13 and the fourth adapter 23 is one. This allows the inlet to withstand greater fluid pressure during use, increases the sealing and strength of the connection between the first adapter 31 and the connector 10 and the adapter 21, and extends the service life of the battery device 100.

[0058] Therefore, by having more first seals than second seals, the reliability of the seal between the first adapter 31 and the first adapter 12 and the second adapter 22 can be improved, providing a certain buffering effect for the heat exchange fluid.

[0059] Optionally, the first and second seals are O-rings made of silicone rubber.

[0060] Optionally, the heat exchanger 20 is provided with two inlets and one outlet. The heat exchange fluid flowing from the first adapter 31 into the adapter 21 is divided into two paths and enters the heat exchange channel 26 of the heat exchanger 20 from different inlets of the heat exchanger 20. After heat exchange, the heat exchange fluid flows out of the heat exchanger 20 from the same outlet, thereby improving the heat exchange efficiency.

[0061] According to some embodiments of the present invention, the connector 10 is provided with a first interface 16, and the adapter 21 is provided with a second interface 24. The first interface 16 and the second interface 24 are respectively engaged with the adapter 30. At least one sealing groove is formed between the first interface 16 and the second interface 24 and the adapter 30, and the first sealing member or the second sealing member is engaged in the sealing groove.

[0062] Optionally, the first interface 16 includes a first sub-interface 14 and a second sub-interface 15. The first sub-interface 14 is connected to the first adapter 31, and the second sub-interface 15 is connected to the second adapter 32. The second interface 24 includes a third sub-interface 232 and a fourth sub-interface 233. The third sub-interface 232 is connected to the first adapter 31, and the fourth sub-interface 233 is connected to the second adapter 32. Multiple first seals are provided between the first sub-interface 14 and the third sub-interface 232 and the first adapter 31, and at least one second seal is provided between the second sub-interface 15 and the fourth sub-interface 233 and the second adapter 32.

[0063] Optionally, the sealing groove can be provided on the first interface 16 or the second interface 24, or on both the first interface 16 and the second interface 24, or on the inner wall of the corresponding adapter 30. In this application, the sealing groove is provided on the outer peripheral wall of the first interface 16 and the second interface 24, and the corresponding adapter 30 mates with the corresponding first interface 16 and the second interface 24 along a third direction C to achieve sealing during assembly. Two sealing grooves are respectively provided between the first adapter 31 and the led-out first interface 16 and the second interface 24, and the two sealing grooves are spaced apart along a third direction C. Two first sealing elements mate within the corresponding sealing grooves. A sealing groove is respectively provided between the second adapter 32 and the led-out first interface 16 and the second interface 24, and a second sealing element mates within the sealing groove.

[0064] Therefore, by forming at least one sealing groove between the first interface 16 and the second interface 24 and the adapter 30, the sealing performance of the first and second seals to the heat exchange fluid can be improved, preventing heat exchange fluid leakage. Simultaneously, it prevents the first and second seals from loosening or falling off, improving the reliability of the seals. Furthermore, it facilitates replacement when maintenance is needed later, reducing maintenance and usage costs.

[0065] In this application, the distance between the two ends of the first interface 16 and the second interface 24 corresponding to the sealing groove along the third direction C is not less than 1mm, so as to avoid the sealing groove from failing to limit the first sealing element and the second sealing element, thereby avoiding sealing failure.

[0066] Optionally, such as Figure 6As shown, the adapter 21 has three connecting ports, including two first connecting ports 25 and one second connecting port. The ends of the two first connecting ports 25 adjacent to the heat exchanger 20 are respectively connected to the two inlets of the heat exchanger 20. The ends of the two first connecting ports 25 away from the heat exchanger 20 are connected to the third sub-interface 232. The end of the second connecting port adjacent to the heat exchanger 20 is connected to the outlet of the heat exchanger 20. The end of the second connecting port away from the heat exchanger 20 is connected to the fourth sub-interface 233. The heat exchange fluid flows sequentially from the external medium source inlet 181 of the connector 10, the first sub-port 14, and the first adapter 31 to the third sub-port 232. Then, it flows from the two first connecting ports 25 to the two inlets of the heat exchange element 20.

The first transition portion 12 and the third transition portion 13 are respectively provided at both ends of the groove along the second direction B. At least a portion of the adapter 21 is provided in the groove. Thus, by providing at least a portion of the adapter 21 between the first transition portion 12 and the third transition portion 13, the mutual positioning of the connector 10 and the adapter 21 is facilitated, improving the assembly efficiency of the battery device 100 and the compactness of the internal structure of the battery device 100. At the same time, it is convenient to make the surfaces of the connector 10 and the adapter 21 flush with the side of the heat exchanger 20 along the third direction C.

The connector 10 is disposed along a first direction A on a side wall of the tray 50 adjacent to the heat exchanger 20. Thus, by integrating the connector 10 onto the tray 50, the integration of the battery device 100 can be improved, as can the reliability and stability of the connector 10's placement. Simultaneously, it facilitates the entry of heat exchange fluid supplied by an external medium source into the battery device 100 through the connector 10.

The battery pack is glued to the tray 50 and the heat exchanger 20 on both sides along the third direction C, respectively. The heat exchanger 20 is connected to the tray 50 by rivets. The inlet and outlet of the heat exchanger 20 are led out through the adapter 21, which is disposed along the third direction C on the side of the heat exchanger 20 facing the tray 50 and along the first direction A towards the connector 10 on the tray 50. Thus, by placing the heat exchanger 20 on top of the battery pack, it is convenient to dissipate heat and cool the battery pack. At the same time, the adapter 21 is disposed on the side of the heat exchanger 20 facing the tray 50, which facilitates the connection of the adapter 30 to both the connector 10 and the adapter 21, shortening the heat exchange path and improving the compactness of the space.
