[0049] In related technologies, the connector assembly is typically located in the middle region of the heat exchanger, and includes an outlet channel and two inlet channels located within the outlet channel. The heat exchange medium enters the heat exchange flow path of the heat exchanger through the two inlet channels. After exchanging heat with the battery, the heat exchange medium flows out of the connector assembly through the middle outlet channel. Because the temperature of the heat exchange medium flowing through the outlet channel is relatively high, the temperature in the area where the connector assembly is located is also relatively high, resulting in a large temperature difference between the area where the connector assembly is located and other areas, thus affecting the uniformity of the heat exchange capacity of the heat exchange device.

[0050] To address the aforementioned technical problems, this application provides a connector assembly, a heat exchange device, and a battery. By setting relatively independent first and second connectors and rationally configuring the positions of the liquid inlet and outlet channels of each connector, the first liquid outlet channel and the second liquid inlet channel are arranged adjacent to each other. The first liquid inlet channel is located on the side of the first liquid outlet channel away from the second liquid inlet channel, and the second liquid outlet channel is located on the side of the second liquid inlet channel away from the first liquid outlet channel. In this way, the heat from the high-temperature first liquid outlet channel can be partially absorbed by the adjacent low-temperature second liquid inlet channel, forming a local heat exchange, reducing the overall temperature difference of the connector assembly, and thus reducing the temperature difference between the area where the connector assembly is located and other areas, improving the uniformity of the heat exchange capacity of the heat exchange device.

[0051] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0052] Please refer to Figure 1 and Figure 2 This application provides a heat exchange device 1000 for exchanging heat with a component to be heat-exchanged, so that the component is within a suitable temperature range. In some embodiments, the component to be heat-exchanged may be a battery module.

[0053] It should be noted that, in this embodiment, heat exchange can be understood as the heat exchange device 1000 being able to cool the battery module or heat it. Specifically, the type of fluid flowing within the heat exchange device 1000 can be freely selected depending on the environment in which the battery module is located. For example, when the heat exchange device 1000 is used to cool the battery module, the fluid may include refrigerant, CO2, ethylene glycol, or water.

[0054] The heat exchange device 1000 includes a heat exchange element 200, which includes a first heat exchange channel 210 and a second heat exchange channel 220. It should be understood that the heat exchange element 200 may include a flow channel plate and a heat spreader plate, wherein the first heat exchange channel 210 and the second heat exchange channel 220 are formed on the flow channel plate by a stamping process. The flow channel plate and the heat spreader plate are then welded together by a brazing process.

[0055] Please refer to Figure 1 , Figures 3 to 6 The heat exchange device 1000 provided in this application embodiment further includes a connector assembly 100, wherein the connector assembly 100 is disposed at the center of the edge of the heat exchange element 200. Figure 1 Taking the orientation shown as an example, the connector assembly 100 is located at the middle of the edge of the heat exchanger 200 extending along the width direction. It should be noted that in this embodiment, the middle can be understood as the position of the center line of the heat exchanger 200, or it can be a position adjacent to the center line.

[0056] Please continue to refer to this. Figure 3 and Figure 4 The connector assembly 100 includes a first connector 110 and a second connector 120. The first connector 110 of the connector assembly 100 is connected to the first heat exchange channel 210, and the second connector 120 of the connector assembly 100 is connected to the second heat exchange channel 220, so as to realize the flow of heat exchange medium in the heat exchange element 200.

[0057] Please refer to Figure 6 The first connector 110 includes a first liquid inlet channel 111 and a first liquid outlet channel 112 that are not interconnected. The first liquid inlet channel 111 and the first liquid outlet channel 112 are adapted to communicate with the first heat exchange channel 210 of the heat exchanger 200. That is, the first heat exchange channel 210 includes a first liquid inlet end 211 and a first liquid outlet end 212, wherein the first liquid inlet end 211 is connected to the first liquid inlet channel 111, and the first liquid outlet end 212 is connected to the first liquid outlet channel 112.

[0058] The second connector 120 is disposed on one side of the first connector 110; and the second connector 120 includes a second liquid inlet channel 121 and a second liquid outlet channel 122 that are not interconnected. The second liquid inlet channel 121 and the second liquid outlet channel 122 are adapted to communicate with the second heat exchange channel 220 of the heat exchanger 200. That is, the second heat exchange channel 220 includes a second liquid inlet end 221 and a second liquid outlet end 222, wherein the second liquid inlet end 221 is connected to the second liquid inlet channel 121, and the second liquid outlet end 222 is connected to the second liquid outlet channel 122.

[0059] The first liquid outlet channel 112 and the second liquid inlet channel 121 are arranged adjacent to each other. The first liquid inlet channel 111 is located on the side of the first liquid outlet channel 112 away from the second liquid inlet channel 121, and the second liquid outlet channel 122 is located on the side of the second liquid inlet channel 121 opposite to the first liquid outlet channel 112. In other words, the first liquid inlet channel 111, the first liquid outlet channel 112, the second liquid inlet channel 121, and the second liquid outlet channel 122 are arranged sequentially in the same direction.

[0060] In this way, the heat from the high-temperature first liquid outlet channel 112 can be partially absorbed by the adjacent low-temperature second liquid inlet channel 121, forming a local heat exchange, reducing the overall temperature difference of the joint assembly 100, thereby reducing the temperature difference between the area where the joint assembly 100 is located and other areas, and improving the uniformity of the heat exchange capacity of the heat exchange device 1000.

[0061] Furthermore, by improving the connector assembly 100, this application embodiment can enhance the design possibilities of the first heat exchange channel 210 and the second heat exchange channel 220, making the heat exchanger 200 stronger and significantly improving its cooling and heating capabilities. This allows the battery module to reach a suitable operating temperature more quickly, which is beneficial for improving the battery module's lifespan and increasing its driving range.

[0062] In one possible implementation, please refer to Figure 7 and Figure 8The first connector 110 includes a first surface 113 and a second surface 114. The first surface 113 is connected to the heat exchanger 200, and the second surface 114 is intersecting and connected to the first surface 113. In other words, the second surface 114 is connected to and intersects with the first surface. For example, the first surface 113 and the second surface 114 are perpendicular to each other.

[0063] Please combine Figure 1 , Figure 6 and Figure 8 The first liquid inlet channel 111 includes a first channel 1111 and a first end 1112 and a second end 1113 that are respectively connected to the first channel 1111. The first end 1112 is disposed on the first surface 113 and the second end 1113 is disposed on the second surface 114.

[0064] The first liquid outlet channel 112 includes a third end 1122 and a fourth end 1123 that are respectively connected to the second channel 1121. The third end 1122 is disposed on the first surface 113 and is located on the side of the first end 1122 facing the second connector 120. The fourth end 1123 is disposed on the second surface 114 and is located on the side of the second end 1113 away from the heat exchanger 200. That is, the fourth end 1123 is disposed above the second end 1113.

[0065] Taking the first liquid inlet channel 111 as an example, the first end 1112 serves as the end of the first liquid inlet channel 111 that connects with the heat exchanger 200, and the second end 1113 serves as the end of the first liquid inlet channel 111 that connects with the external liquid supply device.

[0066] At the same time, please combine Figure 1 , Figure 6 and Figure 8 The second connector 120 includes a third surface 123 and a fourth surface 124. The third surface 123 is connected to the heat exchanger 200, and the fourth surface 124 intersects with the third surface 123. It should be understood that the intersecting connection in this embodiment is the same as the explanation of the intersecting connection of the first surface 113 and the second surface 114 in the above embodiment, and will not be elaborated further in this embodiment.

[0067] The second liquid inlet channel 121 includes a third channel 1211 and a fifth end 1212 and a sixth end 1213 that are respectively connected to the third channel 1211. The fifth end 1212 is disposed on the third surface 123 and is disposed adjacent to the third end 1212. The sixth end 1213 is disposed on the fourth surface 124.

[0068] The second liquid outlet channel 122 includes a seventh end 1222 and an eighth end 1223 that are respectively connected to the fourth channel 1221. The seventh end 1222 is disposed on the third surface 123 and is located on the side of the fifth end 1212 away from the first connector 110. The eighth end 1223 is disposed on the fourth surface 124 and is located on the side of the sixth end 1213 away from the heat exchanger 200.

[0069] With this configuration, the connection ports of the first connector 110 and the second connector 120 to the heat exchanger 200, as well as the connection ports of the first connector 110 and the second connector 120 to the liquid supply device, are located on different planes, avoiding structural interference during installation, simplifying the assembly process, and allowing operators to fix the heat exchanger and pipeline separately without the need for multi-angle synchronous operation, thus reducing the difficulty of installation.

[0070] Please combine Figure 3 and Figure 6 The first channel 1111, the second channel 1121, the third channel 1211 and the fourth channel 1221 each include the first segment 130, the second segment 140 and the third segment 150.

[0071] Please refer to the appendix. Figure 6 The first segment 130 extends along a first direction; the second segment 140 communicates with the first segment 130 and extends along a second direction, wherein the second direction is perpendicular to the first direction; the third segment 150 communicates with the second segment 140 and extends along a direction perpendicular to the heat exchanger 200; the end of the third segment 150 away from the second segment 140 constitutes an end that communicates with the heat exchanger 200. The end of the first segment 130 away from the second segment 140 constitutes an end that connects to the liquid supply device. That is, the end of the first segment 130 away from the second segment 140 constitutes the corresponding second end 1113, fourth end 1123, sixth end 1213, and eighth end 1223. The end of the third segment 150 away from the second segment 140 constitutes the corresponding first end 1112, third end 1122, fifth end 1212, and seventh end 1222.

[0072] Wherein, the first direction is perpendicular to the second surface 114, that is Figure 3 and Figure 6 The X direction is in the middle. The second direction is parallel to the heat exchanger 200, that is... Figure 3 and Figure 6 in the Y direction.

[0073] In this way, each channel is a three-dimensional channel, which reduces eddies caused by abrupt changes in the plane, lowers flow noise, and improves flow stability. Furthermore, the three-dimensional channels can also reduce pressure loss during the heat transfer medium flow process, thereby improving heat transfer efficiency.

[0074] In one possible implementation, please refer to Figure 6 and Figure 7 The second segment 140, with its end facing away from the first segment 130, penetrates the corresponding connector along a second direction. In other words, the second segment of the first connector 110, with its end facing away from the first segment 130, penetrates the first connector 110 along a second direction. The second segment of the second connector 120, with its end facing away from the first segment 130, penetrates the second connector 120 along a second direction.

[0075] The end of the second segment 140 facing away from the first segment 130 is provided with a sealing element 160. In this way, the end of the second segment 140 facing away from the first segment 130 passes through the corresponding connector along the second direction, which can be directly drilled, reducing the manufacturing difficulty of the first connector 110 and the second connector 120.

[0076] In some embodiments, the sealing element 160 is brazed into the second section 140. This brazing creates an integral structure between the sealing element 160 and the second section 140, allowing it to withstand pipeline vibration, thermal expansion and contraction, or mechanical impact (such as the bumpy conditions experienced by an electric vehicle), preventing loosening or detachment. Simultaneously, the brazed sealing surface is flush with the inner wall of the flow channel, preventing sudden contraction / expansion of the flow channel caused by bolts or clamps, thus reducing flow resistance.

[0077] The materials of the first connector 110, the second connector 120, and the sealing element 160 include, but are not limited to, aluminum-manganese (Al-Mn) alloys, such as Al3003, so that the first connector 110, the second connector 120, and the sealing element 160 have excellent corrosion resistance and weldability.

[0078] It should be noted that there are several possible connection positions between the third segment 150 and the second segment 140. For example, the third segment 150 is located in the middle of the second segment 140.

[0079] Please refer to the attached document. Figure 3 In one possible implementation, a first boss 170 is provided on the second surface 114, and a second end 1113 and a fourth end 1123 are disposed on the first boss 170. A second boss 180 is provided on the fourth surface 124, and a sixth end 1213 and an eighth end 1223 are disposed on the second boss 180. In this way, the length of the first segment 130 in the first direction can be extended, which can reduce the flow resistance of the heat exchange medium.

[0080] The connector assembly 100 also includes a connecting plate 190, which is disposed between the connector and the heat exchanger 200 and includes four spaced-apart communication channels 191. The first liquid inlet channel 111 and the first liquid outlet channel 112 are connected to the first heat exchange channel 210 through corresponding communication channels 191. The second liquid inlet channel 121 and the second liquid outlet channel 122 are connected to the second heat exchange channel 220 through corresponding communication channels 191.

[0081] The connecting plate 190 serves as an indirect connection between the joint and the heat exchanger 200, allowing for individual replacement of the joint or heat exchanger without overall disassembly, thus improving the maintenance and replacement efficiency of the heat exchanger 1000.

[0082] It should be noted that the connector and the connecting plate 190 can be detachably connected. For example, the first connector 110 and the second connector 120 are connected to the connecting plate 190 by plugging in, which reduces the difficulty of assembling and disassembling the connector and the connecting plate 190.

[0083] This application also provides a battery, including a battery module and a heat exchange device 1000 as described in any of the above embodiments, wherein the heat exchange device 1000 exchanges heat with the battery module (not shown in the figure).

[0084] By improving the connector assembly of the heat exchange device 1000, more possibilities can be provided for the dual-channel design or even more channel designs of the heat exchange component 200, making the heat exchange component 200 stronger and significantly improving its cooling and heating capabilities. This allows the battery module to operate at a suitable temperature faster and better, which is beneficial for improving the battery module's lifespan and increasing its driving range.

[0085] It should be understood that the battery provided in this embodiment can be used in vehicles to provide electrical energy to the vehicle's electrical devices. For example, the vehicle can be a new energy vehicle, which can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. Accordingly, the electrical devices can be the vehicle's drive mechanism or the vehicle's control system.
