The battery pack provided by the application can sufficiently cool and radiate the battery cell due to the application of the water cooling assembly, and the preparation and assembly processes of the battery pack are more convenient.
The water cooling assembly and the battery pack provided by the application are described in detail below with reference to specific examples.
The present application proposes a water cooling assembly, which includes a plurality of first cooling plates 100, a plurality of second cooling plates 200, a first connector 300, and a second connector 400, as shown with reference to fig. 1 and 2. The water cooling assembly can be applied to a battery pack.
Wherein the first cold water plate and the second cold water plate 200 are basic components of the water cooling assembly of the present application, the first cold water plate 100 and the second cold water plate 200 may provide a mounting basis for other at least part of the components of the water cooling assembly. The first cooling plates 100 and the second cooling plates 200 may be alternately arranged at intervals along the first preset direction such that adjacent to the first cooling plates 100 are the second cooling plates 200. A gap is formed between the adjacent first cooling plate 100 and second cooling plate 200, and the gap is a receiving cavity, and the receiving cavity can place the battery cell 500. The structure and the size of the receiving cavity may be set to match those of the battery cell 500 such that the battery cell 500 may be in contact with the first and second cooling plates 100 and 200 when the battery cell 500 is placed in the receiving cavity, thereby allowing heat generated during the charge and discharge of the battery cell 500 to be transferred to the first and second cooling plates 100 and 200 and to be dissipated through the first and second cooling plates 100 and 200. Thus, the battery cell 500 can keep a relatively low temperature in the charge and discharge process, so that the battery cell 500 has better charge and discharge performance.
The first cooling plate 100 and the second cooling plate 200 may be made of a metal material or a graphene material, so that the first cooling plate 100 and the second cooling plate 200 have better heat dissipation performance, and thus the heat of the battery cell 500 may be sufficiently transferred to the first cooling plate 100 and the second cooling plate 200.
The first cooling plate 100 is provided with a first flow channel, the first flow channel can be used for flowing cooling liquid, and when the cooling liquid flows in the first cooling plate 100, the cooling liquid can absorb heat of the battery cell 500 in contact with the first cooling plate 100, so that the heat of the battery cell 500 can be further transferred, and the heat of the battery cell 500 can be further reduced in the charging and discharging process, so that the charging and discharging performance of the battery cell 500 is further improved. The second cooling plate 200 is provided with a second flow channel, the second flow channel can be used for flowing cooling liquid, and when the cooling liquid flows in the second cooling plate 200, the cooling liquid can absorb the heat of the battery cell 500 in contact with the second cooling plate 200, so that the heat of the battery cell 500 can be further transferred, and the heat of the battery cell 500 can be further reduced in the charging and discharging process, so that the charging and discharging performance of the battery cell 500 is further improved.
The first connection members 300 are disposed between the adjacent first cooling plates 100, and the first connection members 300 can communicate the first flow channels of the adjacent first cooling plates 100, so that the cooling liquid can flow in the first flow channels in the plurality of first cooling plates 100, and thus the heat of the plurality of battery cells 500 can be conducted to the corresponding first cooling plates 100. The second connection members 400 are disposed between the adjacent second cooling plates 200, and the second connection members 400 can communicate the second flow channels of the adjacent second cooling plates 200, so that the cooling liquid can flow in the second flow channels in the plurality of second cooling plates 200, and thus the heat of the plurality of battery cells 500 can be conducted to the corresponding second cooling plates 200.
The first cooling plate 100 has a first end, the second cooling plate 200 has a second end, and the first end of the first cooling plate 100 and the second end of the second cooling plate 200 are relatively far apart, so that when the battery cell 500 is placed between the adjacent first cooling plate 100 and second cooling plate 200, the first end of the first cooling plate 100 and the second end of the second cooling plate 200 are respectively located at two sides of the battery cell 500, so that the first connector 300 and the second connector 400 are relatively far apart. The first connection member 300 may be disposed using a space adjacent to the first end of the first cooling plate 100, the second connection member 400 may be disposed using a space adjacent to the second end of the second cooling plate 200, such that the installation space available for the first connection member 300 and the second connection member 400 is relatively larger, thereby making the first connection member 300 more convenient to install with the adjacent first cooling plate 100, and the second connection member 400 more convenient to install with the adjacent second cooling plate 200. Finally, the difficulty in preparing and assembling the water-cooling assembly is reduced.
In some embodiments, referring to fig. 2 to 4, the first connector 300 of the present application may be specifically configured to include a first water supply line 310 and a first water return line 320, the first water supply line 310 being in communication with the first flow channel of the adjacent first cooling plate 100, and the first water return line 320 being also in communication with the first flow channel of the adjacent first cooling plate 100. Specifically, the cooling liquid in the first flow passage of one of the plurality of first cooling plates 100 may be transferred into the other first cold water plate through the first water supply pipe, and the cooling liquid in the first flow passage of the other first cooling plate 100 may be returned into the first flow passage of one of the plurality of first cooling plates 100 through the first water return pipe 320, so that the cooling liquid may circulate in the first flow passage of the plurality of first cooling plates 100. Thus, the cooling liquid in the first cooling plate 100 has better effect of absorbing heat of the battery cell 500, and the cooling liquid has better effect of radiating heat.
The second connector 400 of the present application may be specifically configured to include a second water supply line 410 and a second water return line 420, the second water supply line 410 being in communication with the second flow passage of the adjacent second cooling plate 200, and the second water return line 420 being also in communication with the second flow passage of the adjacent second cooling plate 200. Specifically, the cooling liquid in the second flow passage of one of the plurality of second cooling plates 200 may be transferred into the other second cooling plate through the second water supply pipe, and the cooling liquid in the second flow passage of the other second cooling plate 200 may be returned into the second flow passage of one of the plurality of second cooling plates 200 through the second water return pipe 420, so that the cooling liquid may circulate in the second flow passage of the plurality of second cooling plates 200. Thus, the cooling liquid in the second cooling plate 200 has better effect of absorbing heat of the battery cell 500, and the cooling liquid has better effect of radiating heat.
In some embodiments, referring to fig. 1, the water cooling assembly of the present application has a first side and a second side, which are two sides of the water cooling assembly in a first predetermined direction, i.e., the first side and the second side are the opposite outermost sides of the water cooling assembly.
The first cooling plate 100 on the first side of the water cooling assembly is provided with a first total liquid inlet 110 and a first total liquid outlet 120, and the first total liquid inlet 110 and the first total liquid outlet 120 are both communicated with the first flow channel of the first cooling plate 100. Specifically, the first total liquid inlet 110 of the first cooling plate 100 may be in communication with an external cooling liquid tank, and the cooling liquid in the cooling liquid tank may be input to the first total liquid inlet 110 through the pumping structure, and then input into the first flow channel of the first cooling plate 100. The cooling fluid in the first cooling plate 100 on the first side of the water cooling assembly may then be input into the other first cooling plates 100 through the first connection 300, and after flowing through all the first flow channels of the first cooling plates 100, flow back into the first flow channels of the first cooling plates 100 on the first side of the water cooling assembly, and finally be discharged through the first total liquid outlet 120. The first total liquid outlet 120 may also be communicated with an external cooling liquid tank, so that the cooling liquid in the cooling liquid tank may circulate through the first flow channels of the plurality of first cooling plates 100, thereby fully utilizing the cooling liquid, or supplementing new cooling liquid into the first cooling plates 100, so that the cooling and heat dissipation effects of the first cooling plates 100 are better.
The second cooling plate 200 on the first side of the water cooling assembly is provided with a second total liquid inlet 210 and a second total liquid outlet 220, and the second total liquid inlet 210 and the second total liquid outlet 220 are both communicated with the second flow channel of the second cooling plate 200. Specifically, the second total liquid inlet 210 of the second cooling plate 200 may be in communication with an external cooling liquid tank, and the cooling liquid in the cooling liquid tank may be input to the second total liquid inlet 210 through the pumping structure, and then input into the second flow channel of the second cooling plate 200. The cooling fluid in the second cooling plate 200 of the second side of the water cooling assembly may then be input into the other second cooling plates 200 through the second connection 400, and after flowing through all the second flow passages of the second cooling plates 200, flow back into the second flow passages of the second cooling plates 200 of the second side of the water cooling assembly, and finally be discharged through the second total liquid outlet 220. The second total liquid outlet 220 may also be communicated with an external cooling liquid tank, so that the cooling liquid in the cooling liquid tank may circulate through the second flow channels of the plurality of second cooling plates 200, thereby fully utilizing the cooling liquid, or supplementing new cooling liquid into the second cooling plates 200, so that the cooling and heat dissipation effects of the second cooling plates 200 are better.
In some embodiments, referring to fig. 5, the first fluid channel in the first cooling plate 100 of the present application specifically includes a first fluid inlet sub-channel 130 and a first fluid outlet sub-channel 140, where the first fluid inlet sub-channel 130 and the first fluid outlet sub-channel 140 are disposed in communication. The first liquid inlet sub-flow channel 130 is also communicated with the first water supply pipeline 310, and the first liquid outlet sub-flow channel 140 is also communicated with the first water return pipeline 320, so that the cooling liquid can be input into the first liquid inlet sub-flow channel 130 through the first water supply pipeline 310, then enter into the first liquid outlet sub-flow channel 140, and finally be conveyed into the next first cooling plate 100 through the first water return pipeline 320.
The direction of the opening at the connection position of the first liquid inlet sub-runner 130 and the first liquid outlet sub-runner 140 intersects with the flowing direction of the cooling liquid in the first liquid inlet sub-runner 130 and the first liquid outlet sub-runner 140, so that the first runner formed by connecting the first liquid inlet sub-runner 130 and the first liquid outlet sub-runner 140 is in a discontinuous straight line structure, that is, the first liquid inlet sub-runner 130 and the first liquid outlet sub-runner 140 are bent or curved, and the path of the first runner can be increased. This allows the coolant to flow through a longer path in the first cooling plate 100, which allows the coolant to more fully absorb the heat of the telecommunications.
In some embodiments, referring to fig. 5, the first liquid inlet sub-channel 130 and the first liquid outlet sub-channel 140 in the first cooling plate 100 may be configured as a straight channel structure, and the first liquid inlet sub-channel 130 and the first liquid outlet sub-channel 140 may be stacked along a second preset direction, where the second preset direction is perpendicular to the first preset direction. In this way, the internal space of the first cooling plate 100 can be fully utilized, so that the paths of the first liquid inlet sub-flow channel 130 and the first liquid outlet sub-flow channel 140 are longer, and the paths through which the cooling liquid can flow in the first cooling plate 100 are also longer, so that the cooling and heat dissipation effects of the first cooling plate 100 are better.
In some embodiments, referring to fig. 5, the first flow channel of the first cooling plate 100 of the present application further includes a second liquid inlet sub-flow channel 150 and a second liquid outlet sub-flow channel 160, and the second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160 are in communication. The second liquid inlet sub-channel 150 is further in communication with the first liquid inlet sub-channel 130, and the second liquid outlet sub-channel 160 is further in communication with the first liquid outlet sub-channel 140, such that the cooling liquid can be input into the second liquid inlet sub-channel 150 through the first liquid inlet sub-channel 130, then enter into the second liquid outlet sub-channel 160, and finally enter into the first liquid outlet sub-channel 140. This can further increase the path length of the first flow passage in the first cooling plate 100, and thus the cooling effect of the first cooling plate 100 is further improved.
The second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160 are also stacked along the second preset direction, and the second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160 are both located between the first liquid inlet sub-flow channel 130 and the first liquid outlet sub-flow channel 140, so that the second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160 are located at a position relatively close to the middle of the first cooling plate 100. The flow of cooling fluid through the second liquid inlet sub-flow path 150 is less than the flow of cooling fluid through the first liquid inlet sub-flow path 130, and the flow of cooling fluid through the second liquid outlet sub-flow path 160 is less than the flow of cooling fluid through the first liquid outlet sub-flow path 140. Such that the flow rates of the cooling liquid in the second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160 are relatively faster, so that the cooling liquid can pass through the second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160 more efficiently.
When the first cooling plate 100 of the present application is in contact with the battery cell 500, the middle portion of the battery cell 500 may be covered by the first cooling plate 100, so that the amount of heat exchange between the middle portion of the telecommunications and the outside air is less. Therefore, the second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160 are positioned at the position relatively close to the middle of the first cooling plate 100, so that the middle position of the electric core 500 can be relatively closer to the second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160, and thus the cooling liquid with higher flow rate in the second liquid inlet sub-flow channel 150 and the second liquid outlet sub-flow channel 160 can more effectively carry away the heat of the middle position of the electric core 500, so that the overall heat dissipation effect of the electric core 500 is relatively uniform, and the local temperature of the electric core 500 is prevented from being too high.
In some embodiments, referring to fig. 1 to 2, a plurality of second cooling plates 200 and a plurality of first cooling plates 100 of the present application may be disposed correspondingly, and the first cooling plates 100 and the second cooling plates 200 on opposite sides of any one of the battery cells 500 may have the same structure, so that the first cooling plates 100 and the second cooling plates 200 may be manufactured by the same process flow, thereby reducing the manufacturing cost of the water cooling assembly of the present application.
In some embodiments, referring to fig. 1, the water cooling assembly of the present application may further include a bottom plate 600, and the plurality of first cooling plates 100 and the plurality of second cooling plates 200 may be disposed on the bottom plate 600 such that the plurality of first cooling plates 100 and the plurality of second cooling plates 200 may be fixed. When the battery cell 500 is located in the accommodating groove between the adjacent first cooling plate 100 and second cooling plate 200, one side end of the battery cell 500 may also contact the bottom plate 600, and the bottom plate 600 may also be provided with a heat dissipation channel through which the cooling liquid flows, so that heat of the battery cell 500 may also be conducted to the bottom plate 600.
In some embodiments, referring to fig. 1 to 2, a side of the first cooling plate 100 facing away from the first connector 300 is aligned with a side edge of the battery cell 500, and a side of the second cooling plate 200 facing away from the second connector 400 is aligned with another side edge of the battery cell 500. This may make the space between the adjacent first cooling plates 100 and the space between the adjacent second cooling plates 200 larger, thereby making the first and second connection members 300 and 400 more convenient to install.
Based on the above water cooling assembly, referring to fig. 1 and 2, the application also provides a battery pack, which comprises an electric core 500 and the above water cooling assembly. The battery cell 500 is disposed in the accommodating groove between the adjacent first cooling plate 100 and second cooling plate 200.
