Description

Technical Field

[0001] This invention relates to the field of thermal management technology, and in particular to a vehicle cooling plate assembly. Background Technology

[0002] The battery pack contains multiple battery modules, thus requiring multiple cooling plates. The inlet and outlet of each cooling plate are located at both ends, necessitating the addition of pipes inside the battery pack to connect the cooling plates. Furthermore, multiple cooling plates also need to be connected together via these pipes. These additional pipes occupy internal space within the battery pack, reducing the space available for the cooling plates and decreasing the contact area between the cooling plates and the battery modules, ultimately impacting the overall heat exchange performance of the battery pack. Summary of the Invention

[0003] Therefore, it is necessary to provide a cooling plate assembly that reduces the space occupied by pipes to address the above problems.

[0004] The technical solution adopted in this invention is as follows:

[0005] A cooling plate assembly includes a plurality of first heat transfer elements, which are disposed separately. Each first heat transfer element has at least one first flow channel and at least one second flow channel. The cooling plate assembly includes a first connector, which has a first flow collecting channel and a second flow collecting channel. The first flow collecting channel and the second flow collecting channel are separated and located on the same side of the first heat transfer element. The first flow collecting channel communicates with the first flow channel, and the second flow collecting channel communicates with the second flow channel. Along the extending direction of the second flow collecting channel, the plurality of first heat transfer elements are disposed separately. The cooling plate assembly has at least one third flow collecting channel, which communicates with the first flow channel and the third flow collecting channel. The third flow collecting channel communicates with the second flow channel. The cooling plate assembly has a first opening and a second opening. The first opening is located on the first connector and communicates with the first flow collecting channel. The second opening is located on the first connector and communicates with the second flow collecting channel.

[0006] In the above technical solution, since the first and second flow channels are both located on the same side of the first heat transfer element, and the first and second openings are both located on the first connector, the first and second openings can be arranged close to each other. In order to bring the first and second openings close together, compared with the arrangement where the first and second flow channels are located on different sides of the first heat transfer element, the fact that the first and second flow channels are both located on the same side of the first heat transfer element in this application can save pipe space, thereby increasing the space available for the first heat transfer element that plays a heat exchange role, thereby increasing the heat exchange performance. Furthermore, since the number of pipes is reduced, the overall total flow resistance is reduced. At the same time, since the first and second flow channels are both located on the same side of the first heat transfer element, at least two flow paths of fluid are realized through the first flow channel, the second flow channel, and the third flow channel, thereby optimizing the heat exchange performance of a single first heat transfer element.

[0007] A cooling plate assembly includes a plurality of first heat transfer elements, wherein the plurality of first heat transfer elements are defined to be disposed separately along a third direction. Each first heat transfer element includes a heat transfer surface, and a fourth direction is defined perpendicular to the heat transfer surface. The angle between the third direction and the fourth direction is greater than or equal to 60° and less than or equal to 90°. Each first heat transfer element has at least one first flow channel and at least one second flow channel. The cooling plate assembly includes a first connector, which has a first flow collecting channel and a second flow collecting channel. The first flow collecting channel and the second flow collecting channel are separated and located on the same side of the first heat transfer element. The first flow collecting channel communicates with the first flow channel, and the second flow collecting channel communicates with the second flow channel. The cooling plate assembly has at least one third flow collecting channel, which communicates with the first flow channel and the third flow collecting channel. The cooling plate assembly has a first opening and a second opening, wherein the first opening is located on the first connector and communicates with the first flow collecting channel, and the second opening is located on the first connector and communicates with the second flow collecting channel.

[0008] In the above technical solution, the angle between the third direction and the fourth direction is greater than or equal to 60° and less than or equal to 90°, that is, the deflection of the heat transfer surface is less than or equal to 30°, thereby improving the uniformity of flow distribution and improving heat exchange efficiency. Since the first and second flow collection channels are both located on the same side of the first heat transfer element, and the first and second openings are both located on the first connector, the first and second openings can be set close to each other. In order to bring the first and second openings close together, compared with the arrangement of the first and second flow collection channels being located on different sides of the first heat transfer element, the fact that the first and second flow collection channels are both located on the same side of the first heat transfer element in this application can save pipe space, thereby increasing the space available for the first heat transfer element that plays a heat exchange role, thereby increasing the heat exchange performance. Furthermore, due to the reduction of pipes, the overall total flow resistance is reduced. At the same time, since the first and second flow collection channels are both located on the same side of the first heat transfer element, at least two flow paths of fluid are realized through the first flow channel, the second flow channel, and the third flow collection channel, optimizing the heat exchange performance of a single first heat transfer element.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and technical solutions. It should be understood that the specific technical solutions described herein are merely illustrative of the invention and are not intended to limit the invention.

[0028] Please see Figures 1-16This invention provides a cooling plate assembly comprising multiple first heat transfer elements 1, defined as being discretely arranged along a third direction. Each first heat transfer element 1 includes a heat transfer surface 87, and a fourth direction is defined as being perpendicular to the heat transfer surface 87. The angle between the third direction and the fourth direction is greater than or equal to 60° and less than or equal to 90°. In this technical solution, the first heat transfer element 1 is a flat tube, and the multiple first heat transfer elements 1 are discretely arranged along the third direction. One first heat transfer element 1 corresponds to one battery module. Heat exchange can be performed on multiple battery modules through the heat transfer surface 87. In this technical solution, the heat transfer surface 87 is a plane, and the angle between the fourth direction and the third direction is 90°. Each first heat transfer element 1 has at least one first flow channel 11 and at least one second flow channel 12. The fluid flows in the first flow channel 11 and the second flow channel, exchanging heat with the corresponding battery module. The cooling plate assembly includes a first connector 2, which has a first flow collecting channel 21 and a second flow collecting channel 22. The first flow collecting channel 21 and the second flow collecting channel 22 are separated and located on the same side of the first heat transfer element 1. The first flow collecting channel 21 is connected to the first flow channel 11, and the second flow collecting channel 22 is connected to the second flow channel 12. The cooling plate assembly has at least one third flow collecting channel 31, which is connected to the first flow channel 11 and the second flow collecting channel 31. The flow direction of the fluid in the cooling plate assembly is that it first flows into the first flow collecting channel 21 and then completes heat exchange in the first flow collecting channel 21. After distribution, the fluid enters the first flow channel 11 of multiple first heat transfer elements 1, flows through the first heat transfer elements 1 respectively along the first flow channel 11, and exchanges heat with the battery module through the surface of the first heat transfer elements 1. Then it enters the third flow channel 31, flows into the second flow channel 12 through the third flow channel 31, flows through the multiple first heat transfer elements 1 again through the second flow channel 12, and exchanges heat with the battery module through the surface of the first heat transfer elements 1. Then it enters the second flow channel 22, and finally flows out of the cooling plate assembly. It should be noted that "flowing through" here refers to flowing through the interior of the first heat transfer elements 1. The flow direction of the fluid in the first flow channel 11 and the second flow channel 12 is opposite. It should be noted that "opposite" here means that the fluid in the first flow channel 11 flows from the first heat transfer element 1... The flow proceeds from one end 13 to the opposite second end 14, while in the second flow channel 12, the flow proceeds from the second end 14 of the first heat transfer element 1 to the opposite first end 13. The specific flow path from the first end 13 to the second end 14 and from the second end 14 to the first end 13 may not be completely opposite. The cooling plate assembly has a first opening 41 and a second opening 42. The first opening 41 communicates with the first collecting channel 21, and the second opening 42 communicates with the second collecting channel 22. Since the first collecting channel 21 and the second collecting channel 22 are both located on the same side of the first heat transfer element 1, the first opening 41 and the second opening 42 can be arranged close to each other without the need to add other pipes to make the first opening 41 and the second opening 42 close together, thus saving space.This increases the usable space of the first heat transfer element 1, which plays a role in heat exchange, thereby increasing heat exchange performance. Furthermore, by reducing unnecessary pipes, the overall flow resistance is reduced. In this technical solution, fluid flows into the first manifold 21 from the first opening 41 and out of the second manifold 22 from the second opening 42. In other technical solutions, fluid can also flow into the second manifold 22 from the second opening 42, and then into the second flow channel 12. It flows through multiple first heat transfer elements 1 via the second flow channel 12, then enters the third manifold 31, flows into the first flow channel 11, flows along the first flow channel 11 through multiple first heat transfer elements 1, then enters the first manifold 21, and exits through the first opening 41. In this technical solution, the first flow channel 11, the second flow channel 12, and the third manifold 31 enable the fluid to achieve a dual-flow process within a single first heat transfer element 1; that is, the first flow channel 11 is the first flow, and the second flow channel 12 is the second flow. It should be noted that "first" and "second" here do not indicate order, but only describe the flow path. Because the temperature of the fluid increases with the increase of heat exchange time when the fluid exchanges heat with the battery module, the heat exchange effect of the fluid on the battery module gradually decreases. For the first heat transfer element 1, the heat exchange effect is best at the fluid inflow point and worst at the fluid outflow point, and the heat exchange effect gradually decreases along the fluid flow path. Therefore, in a single-flow first heat transfer element 1, the heat exchange effect of each region of the first heat transfer element 1 is different, which in turn leads to different heat exchange effects on each region of the battery module. This application achieves dual-flow flow of the fluid without changing the space occupied by the first heat transfer element 1, placing the fluid inflow and outflow ends on the same side of the first heat transfer element 1. That is, the region with the best and worst heat exchange effect is located on the same side of the first heat transfer element 1, thereby balancing the overall heat exchange balance of the first heat transfer element 1 and optimizing the heat exchange performance of the individual first heat transfer element 1.

[0029] Further, please refer to Figures 1-5 , Figure 10 , Figure 11The first connecting component 2 includes a first manifold 23 and a second manifold 24. The first manifold 23 has a first manifold channel 21, and the second manifold 24 has a second manifold channel 22. The first manifold 23 and the second manifold 24 are fixedly connected. In this technical solution, the first manifold 23 has a first manifold channel 21, and the second manifold 24 has a second manifold channel 22. The first manifold 23 and the second manifold 24 are arranged side by side and fixedly connected, reducing the distance between the first manifold channel 21 and the second manifold channel 22, and shortening the distance between the first opening 41 and the second opening 42. This reduces the unnecessary pipe arrangement, lowers the total flow resistance of the cooling plate assembly, reduces the space occupied by non-heat exchange components, and thus increases the space occupied by the first heat transfer component 1, thereby increasing the heat exchange performance. The second manifold 24 has a first connection port 241, and the first heat transfer component 1 is sealed to the first connection port 241. The first manifold 23 has a second connection port 231, and the first heat transfer component 1 is enclosed in... The device includes multiple connecting parts 5, which are sealed to the second connecting port 231. The first flow channel 11 is connected to the first flow collection channel 21 through the connecting parts 5. In this technical solution, the connecting parts 5 and the first heat transfer element 1 are integrated. The connecting parts 5 are sealed to the second connecting port 231. The first flow channel 11 is connected to the first flow collection channel 21 through the connecting parts 5. There is no need to add a pipe to connect the first heat transfer element 1 and the first connecting part 2. The first flow channel 11 is directly connected to the first flow collection channel 21 through the connecting parts 5 integrated with the first heat transfer element 1. Therefore, for the overall cooling plate assembly, the space occupied by the pipes that do not play a heat exchange role is reduced, thereby allowing the first heat transfer element 1, which actually plays a heat exchange role, to have more usable space, thereby improving the heat exchange performance. In addition, in this technical solution, the connecting parts 5 and the first heat transfer element 1 are integrated, which reduces the difficulty of connecting the connecting parts 5 to the wall forming the first flow collection channel 21.

[0030] Furthermore, the second manifold 24 has a third connection port 232, which connects to the second connection port 231. The third connection port 232 in the second manifold 24 allows for connection with the second connection port 231 without the need for a separate pipe connection, making the structure of the first manifold 23 and the second manifold 24 more compact and reducing the space required for installing the first connector 2. The connecting part 5 is located within the first connector 2, partially within the second manifold 24, and partially within the first manifold 23. This design ensures that the connecting part 5 does not increase the installation space requirement for the overall cooling plate assembly, allowing the first heat transfer element 1, which actually performs the heat exchange function, more usable space and thus improving heat exchange performance. The first surface is perpendicular to the extending direction of the second flow channel 22. For the orthographic projection of the cross-section of any connecting portion 5 onto the first surface, at least a portion of the flow cross-sectional area of ​​the second flow channel 22 does not coincide with the orthographic projection. Because at least a portion of the flow cross-sectional area of ​​the second flow channel 22 does not coincide with the orthographic projection, the second flow channel 22 has a gap at the connecting portion 5, allowing fluid to flow through the gap. It should be noted that this flow is from the outside of the connecting portion 5 and does not contact the fluid inside the connecting portion 5. Since the second flow channel 22 is connected to the second flow channels 12 of the plurality of first heat transfer elements 1, the size of the connecting portion 5 within the second flow channel 22 is limited so that the medium can flow in the second flow channel 22 and the second flow channels 12. Therefore, the fluid within the second flow channel 22 can flow into the plurality of first heat transfer elements 1. Of course, in other technical solutions, the connecting portion 5 can also be fixedly connected to the wall forming the first flow channel 21, and the connecting portion 5 can be fixedly connected to the first heat transfer element 1.

[0031] Further, please refer to Figures 1-3 , Figure 11The first connection port 241 includes a first flange 81, which is arranged circumferentially along the first heat transfer element 1. The first flange 81 is sealed to the first heat transfer element 1, increasing the contact area between the first connection port 241 and the first heat transfer element 1, thereby increasing the welding area between the first connection port 241 and the first heat transfer element 1, enhancing the welding reliability between the first connection port 241 and the first heat transfer element 1, and reducing the probability of leakage at the connection between the first connection port 241 and the first heat transfer element 1. Alternatively, a second flange 82 can be further provided at the second connection port 231, which is arranged circumferentially along the connecting portion 5 and is sealed to the connecting portion 5, increasing the contact area between the second connection port 231 and the first heat transfer element 1. The second flange 82 is placed at the third connection port 232. The second flange 82 is arranged along the circumference of the connection port 5 and is sealed to the connection port 5. The second flange 82 increases the contact area between the third connection port 232 and the connection port 5, thereby increasing the welding area between the third connection port 232 and the connection port 5, enhancing the welding reliability between the third connection port 231 and the connection port 5, and reducing the probability of leakage at the connection between the third connection port 232 and the connection port 5.

[0032] Further, please refer to Figures 1-5 , Figure 7 , Figure 15 Define a first direction and a second direction. The first direction is the arrangement direction of the first heat transfer element 1 relative to the second manifold 24, and the second direction is the arrangement direction of the first manifold 23 relative to the second manifold 24. The angle between the first direction and the second direction is greater than 0° and less than 180°. The first manifold 21 and the second manifold 22 are both located on the same side of the first heat transfer element 1. Therefore, the first opening 41 and the second opening 42 can be set close to each other without the need to add other pipes to make the first opening 41 and the second opening 42 close to each other, saving space and increasing the space available for the first heat transfer element 1 that plays a heat exchange role, thereby increasing the heat exchange performance.

[0033] Furthermore, a first direction is defined as the arrangement direction of the first heat transfer element 1 relative to the second manifold 24. Along the first direction, the first heat transfer element 1 is located on one side of the second manifold 22, and the first manifold 21 is located on the other side of the second manifold 22. Since the connecting part 5 and the first heat transfer element 1 are integrally formed, and the connecting part 5 is located inside the first connecting part 2, and the connecting part 5 is fixedly connected to the second connecting port 231, the first manifold 21 and the second manifold 22 are arranged side by side, and both the first manifold 21 and the second manifold 22 are located on the same side of the first heat transfer element 1. The first opening 41 and the second opening 42 can be arranged close to each other without the need to add other pipes to make the first opening 41 and the second opening 42 close to each other. The opening 42 is close to the space, which saves space and increases the usable space of the first heat transfer element 1 that plays a heat exchange role, thereby increasing the heat exchange performance. The first flow channel 21, the second flow channel 22 and the first heat transfer element 1 are arranged along the first direction. Therefore, the first heat transfer element 1 is fixedly connected to the first connecting member 2. The connecting part 5 can be completely located in the first connecting member 2 and fixedly connected to the second connecting port 231. Thus, although the first flow channel 21 is connected to the first flow channel 11 by the connecting part 5, the space occupied by the component that does not play a heat exchange role is reduced because the connecting part 5 is located in the first connecting member 2. This increases the usable space of the component that plays a heat exchange role, namely the first heat transfer element 1, thereby improving the heat exchange performance.

[0034] Further, please refer to Figures 1-5 , Figure 15 The cooling plate assembly includes a first connector 6 and a second connector 7. The first connector 6 has a fourth flow channel 61 and a first opening 41, which communicates with the fourth flow channel 61 and the fourth flow channel 61. The fourth flow channel 61 communicates with the first collection channel 21. The second connector 7 has a fifth flow channel 71 and a second opening 42, which communicates with the fifth flow channel 71 and the fifth flow channel 71. In this technical solution, fluid flows in from the first opening 41, flows through the fourth flow channel 61 and enters the first collection channel 21. The fluid flows into the fifth flow channel 71 through the second collection channel 22 and flows out through the second opening 42. In this technical solution, the medium directly enters and exits through the first connector 6 and the second connector 7 without the need for additional pipes. For the cooling plate assembly as a whole, this reduces the space occupied by pipes and increases the usable space of the heat exchange component, namely the first heat transfer element 1, thereby improving the heat exchange performance.

[0035] Further, please refer to Figure 3 , Figure 4 , Figure 10 , Figure 11 , Figure 16The first manifold 23 has a fourth connection port 233, which has a third flange 83. The third flange 83 is arranged circumferentially around the first connector 6 and is sealed to the first connector 6. The third flange 83 increases the welding area between the first connector 6 and the fourth connection port 233, thereby increasing the welding reliability of the first connector 6 and the fourth connection port 233 and reducing the probability of leakage of the medium at the connection between the first connector 6 and the fourth connection port 233. The first manifold 23 also has a fifth connection port 234, which has a fourth flange 84. The fourth flange 84 is arranged circumferentially around the second connector 7 and is sealed to the second connector 7. The fourth flange 84 increases the welding area between the second connector 7 and the fifth connection port 234, thereby increasing the welding reliability of the second connector 7 and the probability of leakage of the medium at the connection between the second connector 7 and the fifth connection port 234. To reduce the probability of leakage at the connection of the connector 234, the first manifold 23 has a sixth connector 235, which has a fifth flange 85. The fifth flange 85 is arranged around the second connector 7 and is sealed to the second connector 7. The fifth flange 85 increases the welding area between the second connector 7 and the sixth connector 235, thereby increasing the welding reliability between the second connector 7 and the sixth connector 235 and reducing the probability of leakage of the medium at the connection between the second connector 7 and the sixth connector 235. The second manifold 24 has a seventh connector 242, which has a sixth flange 86. The sixth flange 86 is arranged around the second connector 7 and is sealed to the second connector 7. The sixth connector 235 and the seventh connector 242 are connected. The second connector 7 extends through the seventh connector 242 and the sixth connector 235 to the second manifold 24.

[0036] Further, please refer to Figures 1-9 In this technical solution, the first heat transfer element 1 has one set of first flow channels 11 and two sets of second flow channels 12, realizing a dual-flow path with one inlet and two outlets. The number of first flow channels 11 and second flow channels 12 is the same, and each first flow channel 11 is connected to a third flow channel 51. Given that the flow cross-sections of the first flow channels 11 and second flow channels 12 are the same, the total flow cross-sectional area of ​​the fluid flowing from the first end 13 to the second end 14 of the first heat transfer element 1 is equal to the flow cross-sectional area from the second end 14 to the first end 14. The total flow cross-sectional area of ​​the fluid flowing from end 14 to the first end 13 is similar, which reduces the change in fluid resistance. In other technical solutions, the first heat transfer element 1 can also have two sets of first flow channels 11 and one set of second flow channels 12 to realize a two-inlet and one-outlet dual-flow process. The inlet and outlet ends of the fluid are located at the same end of the first heat transfer element 1, that is, the area with the best and worst heat exchange effect is located at the same end of the first heat transfer element 1, thereby balancing the overall heat exchange balance of the first heat transfer element 1 and optimizing the heat exchange performance of the individual first heat transfer element 1.

[0037] Further, please refer to Figures 1-3 , Figures 10-14 A first direction is defined as the arrangement direction of the first heat transfer element 1 relative to the second manifold 24. Along the first direction, the first heat transfer element 1 is located on one side of the second manifold 22, and the first manifold 21 is located on the other side of the second manifold 22. The first manifold 21 and the second manifold 22 are arranged side by side, and both the first manifold 21 and the second manifold 22 are located on the same side of the first heat transfer element 1. The first opening 41 and the second opening 42 can be arranged close to each other without the need to add other pipes to make the first opening 41 and the second opening 42 close together, saving space and increasing the space available for the first heat transfer element 1 to perform heat exchange, thereby increasing the heat exchange performance. The cooling plate assembly includes a second connector 3, which is located on one side of the first heat transfer element 1 along the first direction. The first connector 2 is located on the other side of the first heat transfer element 1. The second connector 3 has a third flow channel 31. Since the first flow channel 11 is connected to the third flow channel 31 and the second flow channel 12 is connected to the third flow channel 31, the fluid in the first flow channel 11 and the fluid in the second flow channel 12 are reversed at the third flow channel 31. Therefore, the second connector 3 is set at the other end of the first heat transfer element 1 relative to the first connector 2 to increase the heat exchange path of the fluid and thus improve the heat exchange performance of the first heat transfer element 1. The second connector 3 is fixedly connected to the first heat transfer element 1. It is fixedly connected to multiple first heat transfer elements 1 through one connector. Therefore, one side of the first heat transfer element 1 is fixedly connected to the first connector 2 and the other side of the first heat transfer element 1 is fixedly connected to the second connector 3, thereby strengthening the strength of the cooling plate assembly. The second connector 3 has multiple third flow channels 31, which are spaced apart. The number of third flow channels 31 is the same as the number of first heat transfer elements 1. Each third flow channel 31 corresponds to one first heat transfer element 1. The first flow element is sealed to the second connector 3. In other technical solutions, the cooling plate assembly may also include multiple second connectors 3, the number of which is the same as the number of first heat transfer elements 1. Each second connector 3 is fixedly connected to one first heat transfer element 1. Each second connector 3 has a third flow channel 31. The first heat transfer element 1 is fixedly connected to the second connector 3, thereby improving the strength of the cooling plate assembly. The first flow channel 11, the second flow channel 12, and the third flow channel 31 are connected.

[0038] Further, please refer to Figures 12-14The number of second connecting parts 3 is one. One second connecting part 3 is fixedly connected to multiple first heat transfer elements 1. The second connecting part 3 includes multiple plate groups 33. The number of plate groups 33 is the same as the number of first heat transfer elements 1. One plate group 33 corresponds to one first heat transfer element 1. The plate group 33 includes two plates 331. Along the width direction of the first heat transfer element 1, the two plates 331 are located on both sides of the corresponding first heat transfer element 1. The third flow channel 31 is located between the two plates 331. The fluid flows from the first flow to the third flow channel 31. It is restricted by the two plates 331. The fluid can only flow in the third flow channel 31 between the plates 331. It flows to the second flow channel 12 through the third flow channel 31. The plates 331 are set close to the corresponding first heat transfer element 1. The size of the third flow channel 31 is controlled to be similar to the width of the first heat transfer element 1. This reduces the risk of fluid accumulation in the third flow channel 31 due to the third flow channel 31 being too large, thus reducing the impact on heat transfer performance.
