Detailed Implementation

[0043] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0044] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0045] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0046] Please refer to Figures 1-4 This utility model embodiment provides a liquid cooling plate 100, which has an inlet 110 and an outlet 120 formed at both ends. The liquid cooling plate 100 is provided with an energy absorption part 130 and a flow channel part 140. The flow channel part 140 includes a first flow channel 141, a second flow channel 142 and a third flow channel 143. One end of the first flow channel 141 is connected to the inlet 110. One end of the second flow channel 142 is connected to the outlet 120. The two ends of the third flow channel 143 are connected to the other ends of the first flow channel 141 and the second flow channel 142, respectively.

[0047] Specifically, the coolant flows into the first flow channel 141 from the inlet 110, then flows through the first flow channel 141, the third flow channel 143, and the second flow channel 142 in sequence, and finally flows out from the outlet 120. Because the liquid cooling plate 100 and the battery cell 310 are in close contact, the coolant can exchange heat with the battery cell 310 when flowing in the first flow channel 141, the second flow channel 142, and the third flow channel 143, thereby carrying away the heat from the battery cell 310 and cooling it.

[0048] In this embodiment, the first flow channel 141, the second flow channel 142, and the third flow channel 143 all extend along the length of the liquid cooling plate 100. Since the two ends of the third flow channel 143 are connected to the first flow channel 141 and the second flow channel 142 respectively, it can be understood that the flow channel portion 140 in this embodiment is serpentine, thereby increasing the flow time of the coolant in the flow channel portion 140, and thus increasing the heat exchange time between the coolant and the battery cell 310, so as to improve the cooling efficiency.

[0049] It should be noted that during the operation of the battery cell 310, the charging and discharging of the battery cell 310 generates expansion force, causing the battery cell 310 to expand. Since the battery cell 310 is in contact with the energy-absorbing part 130 of the liquid cooling plate 100, the battery cell 310 will compress the energy-absorbing part 130 when it expands. In this embodiment, the energy-absorbing part 130 is provided with an energy-absorbing cavity 131 and a through hole, so that the gas in the energy-absorbing cavity 131 can be discharged through the through hole, thereby playing a role in energy absorption and buffering. Therefore, it can be understood that the energy-absorbing part 130 in this embodiment should be located in the middle of the liquid cooling part to improve the buffering effect on the battery cell 310.

[0050] Furthermore, in this embodiment, the first flow channel 141, the second flow channel 142, and the third flow channel 143 are all spaced apart from the energy absorption section 130; this can be understood as the first flow channel 141, the second flow channel 142, and the third flow channel 143 being spaced apart from the energy absorption cavity 131, that is, the first flow channel 141, the second flow channel 142, and the third flow channel 143 are not connected to the energy absorption cavity 131, thus preventing coolant from entering the energy absorption cavity 131.

[0051] Based on the above, in this embodiment, there are multiple energy-absorbing sections 130, which are spaced apart along the length of the liquid cooling plate 100. The third flow channel 143 in this embodiment includes multiple first sub-flow channels 144, multiple second sub-flow channels 145, and multiple third sub-flow channels 146; each energy-absorbing section 130 has a corresponding first sub-flow channel 144 and a second sub-flow channel 145 on both sides; thereby allowing the coolant to bypass the energy-absorbing section 130 and continue flowing into the second flow channel 142.

[0052] A third sub-channel 146 is provided between two adjacent energy-absorbing sections 130; each end of the third sub-channel 146 is connected to two adjacent first sub-channels 144 and two adjacent second sub-channels 145, respectively. Understandably, the coolant in the first sub-channel 144 and the coolant in the second sub-channel 145 located in one section of the third sub-channel 146 mixes through the third sub-channel 146, and then continues through the first sub-channel 144 and the second sub-channel 145 at the other end of the third sub-channel 146.

[0053] It should be noted that in this embodiment, the first sub-channel 144, the second sub-channel 145, and the third sub-channel 146 are all spaced apart from the energy-absorbing part 130. Thus, the first sub-channel 144, the second sub-channel 145, and the third sub-channel 146 ensure that the flow of coolant is not obstructed by the energy-absorbing part 130 located in the middle of the liquid cooling plate 100, and also prevent it from flowing into the energy-absorbing cavity 131.

[0054] The first sub-channel 144 and the second sub-channel 145 corresponding to the energy-absorbing part 130 near the inlet 110 are connected to the second channel 142; while the first sub-channel 144 and the second sub-channel 145 corresponding to the energy-absorbing part 130 near the outlet 120 are connected to the first channel 141.

[0055] Understandably, coolant enters the first flow channel 141 from the inlet 110. The first flow channel 141 extends along the length of the liquid cooling plate 100, causing the coolant to gradually move away from the inlet 110 and closer to the outlet 120. Therefore, the first sub-flow channel 144 and the second sub-flow channel 145, which are near the outlet 120, are connected to the first flow channel 141. After the coolant flows from the first flow channel 141 into the third flow channel 143, since the third flow channel 143 extends along the length of the liquid cooling plate 100, the coolant gradually moves away from the outlet 120 and closer to the inlet 110. Therefore, the first sub-flow channel 144 and the second sub-flow channel 145, which are near the energy-absorbing part 130 of the inlet 110, are connected to the second flow channel 142.

[0056] In other embodiments, only one energy-absorbing section 130, a first sub-channel 144, and a second sub-channel 145 may be provided, with the first sub-channel 144 and the second sub-channel 145 respectively disposed on both sides of the energy-absorbing section 130. The two ends of the first sub-channel 144 and the two ends of the second sub-channel 145 are connected to the first channel 141 and the second channel 142 respectively, so in other embodiments, the third sub-channel 146 may not be provided.

[0057] Therefore, in this embodiment, sub-channels are provided on both sides of the energy absorption section 130 to ensure the uniformity of cooling, avoid large temperature differences at different locations of the battery cell 310, and ensure the uniformity of different temperatures of the battery cell 310.

[0058] Please refer to Figures 1-5 This embodiment also provides a liquid cooling assembly 200, which includes a first thermally conductive support 210, a second thermally conductive support 220, and a liquid cooling plate 100. The first thermally conductive support 210 is disposed in the spaced area between the energy absorption portion 130 and the first flow channel 141, the second flow channel 142, and the third flow channel 143. The second thermally conductive support 220 is sleeved on the outer edge of the liquid cooling plate 100. Both the first thermally conductive support 210 and the second thermally conductive support 220 are in contact with the battery cell 310 to better transfer the heat of the battery cell 310 to the liquid cooling plate 100, thereby improving the cooling efficiency. Furthermore, the first thermally conductive support 210 and the second thermally conductive support 220, together with the energy-absorbing part 130, work together to buffer the liquid cooling plate 100 from deformation and displacement caused by the expansion force generated by the battery cell 310, thereby supporting the battery cell 310 and the liquid cooling plate 100 and improving the sealing performance and structural stability of the liquid cooling plate 100.

[0059] It should be noted that the liquid cooling plate 100 in this embodiment can be formed by stamping, and the energy-absorbing part 130 and the flow channel part 140 in the liquid cooling plate 100 are both structures formed by protrusions on opposite sides of the liquid cooling plate 100. Therefore, there are two first thermally conductive supports 210 in this embodiment, and the two first thermally conductive supports 210 are respectively disposed on opposite sides of the liquid cooling plate 100.

[0060] Based on the above, this embodiment also includes two insulating plates 230 respectively disposed on opposite sides of the liquid cooling plate 100, thereby isolating the liquid cooling plate 100 and the battery cell 310. Since the liquid cooling plate 100 is generally formed by stamping a metal plate, the insulating plates 230 are provided in this embodiment to prevent the liquid cooling plate 100 and the battery cell 310 from conducting electricity and causing a short circuit. It should be noted that the insulating plates 230 in this embodiment have thermal conductivity, thereby transferring the heat from the battery cell 310 to the liquid cooling plate 100 to improve cooling efficiency.

[0061] Please refer to Figures 1-8 This embodiment also provides a battery module 300, which includes a plurality of battery cells 310 and a plurality of liquid cooling components 200. The plurality of liquid cooling components 200 are spaced apart along a direction perpendicular to the length of the liquid cooling plate 100, and any two adjacent liquid cooling components 200 are provided with at least one battery cell 310, and are respectively attached to both sides of the corresponding battery cell 310, that is, each battery cell 310 is attached to two liquid cooling plates 100, thereby improving cooling efficiency.

[0062] Similarly, each liquid cooling plate 100 has a battery cell 310 attached to both opposite sides, so that one liquid cooling plate 100 can cool multiple battery cells 310. It should be noted that there are multiple energy absorbing parts 130 in this embodiment, and each energy absorbing part 130 has two battery cells 310 on each opposite side. That is, the number of battery cells 310 between two adjacent liquid cooling plates 100 is equal to the number of energy absorbing parts 130 in a single liquid cooling plate 100.

[0063] Furthermore, in this embodiment, the liquid cooling assembly 200 also includes a first pipe 240 and a second pipe 250. The first pipe 240 has two first sub-pipes 241, and the second pipe 250 has two second sub-pipes 251. One end of each of the two first sub-pipes 241 is connected to an inlet 110 of a liquid cooling plate 100, and the other end is used to connect to a first sub-pipe 241 on an adjacent liquid cooling plate 100. Similarly, one end of each of the two second sub-pipes 251 is connected to an outlet 120 of a liquid cooling plate 100, and the other end is used to connect to a second sub-pipe 251 on an adjacent liquid cooling plate 100.

[0064] There are adjacent liquid cooling plates 100 on both sides of the liquid cooling plate 100, and two first sub-pipes 241 are respectively connected to the first sub-pipes 241 on the two adjacent liquid cooling plates 100, that is, any two adjacent first sub-pipes 241 are connected. Two second sub-pipes 251 are respectively connected to the second sub-pipes 251 on the two adjacent liquid cooling plates 100, that is, any two adjacent second sub-pipes 251 are connected.

[0065] Based on the above, it can be seen that in this embodiment, the first pipe 240 passes through the inlet 110 of the liquid cooling plate 100 and is connected to the first flow channel 141 through the inlet 110, and any two adjacent first pipes 240 are connected. The second pipe 250 passes through the outlet 120 of the liquid cooling plate 100 and is connected to the second flow channel 142 through the outlet 120, and any two adjacent second pipes 250 are connected.

[0066] Furthermore, the battery module 300 in this embodiment also includes a third tube 340 and a fourth tube 350. The third tube 340 is connected to the first sub-tube 241 of the outermost liquid cooling plate 100, and the fourth tube 350 is connected to the second sub-tube 251 of the outermost liquid cooling plate 100. Coolant flows in through the third sub-tube and then flows through a plurality of sequentially connected first sub-tubes 241 to enter the liquid cooling plate 100 corresponding to the first sub-tube 241. After absorbing the heat of the battery cell 310, the coolant flows in through the second sub-tube 251. The plurality of second sub-tubes 251 are sequentially connected, so that the coolant in the plurality of liquid cooling plates 100 can all flow out through the fourth tube 350.

[0067] Understandably, multiple sequentially connected first pipes 240 form an inlet liquid collection plate, and multiple sequentially connected second pipes 250 form an outlet liquid collection plate. That is, in this embodiment, the coolant flows into the inlet liquid collection plate through the third pipe 340, and then flows into multiple liquid cooling plates 100. After absorbing the heat of the battery cell 310, the coolant enters the outlet liquid collection pipe and finally flows in from the fourth pipe 350.

[0068] According to the above, the battery module 300 in this embodiment also includes a first flexible sleeve 320 and a second flexible sleeve 330. The first flexible sleeve 320 is sleeved at the connection of two adjacent first pipes 240, and the second flexible sleeve 330 is sleeved at the connection of two adjacent second pipes 250.

[0069] Because the battery cell 310 expands due to charging and discharging, the distance between the liquid cooling plates 100 changes. The first flexible sleeve 320 and the second flexible sleeve 330 are flexible to improve the sealing of the battery module 300 and prevent the two adjacent first pipes 240 from breaking, which would cause coolant leakage. Furthermore, the first flexible sleeve 320 and the second flexible sleeve 330 also act as a buffer to absorb the expansion force of the battery cell 310.

[0070] In summary, this embodiment improves cooling efficiency by providing a first flow channel 141 connected to the inlet 110, a second flow channel 142 connected to the outlet 120, and a third flow channel 143 connected at both ends to the first and second flow channels 141 and 142 respectively, making the flow channel portion 140 serpentine. This increases the flow time of the coolant within the liquid cooling plate 100. Furthermore, this embodiment provides energy-absorbing portions 130 spaced apart from the first, second, and third flow channels 141, 142, and 143 to absorb the expansion force generated by the charging and discharging of the battery cell 310, thus providing a buffer and enhancing the protection of the battery cell 310 and the liquid cooling plate 100.

[0071] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
