[0007] In the heat exchange assembly of the embodiment of the present application, the first heat exchange channel and the second heat exchange channel are arranged in parallel, so that the heat exchange medium is divided into two streams after flowing out of the inlet channel of the body. One stream of heat exchange medium flows into the first heat exchange channel and exchanges heat with the first power module while flowing in the first heat exchange channel, while the other stream of heat exchange medium flows into the second heat exchange channel and exchanges heat with the second power module while flowing in the second heat exchange channel. Finally, the two streams of heat exchange medium flow into the outflow channel, merge, and are discharged, thus achieving heat exchange between the first power module and the second power module. In this process, the two streams of heat exchange medium flow through the first heat exchange channel and the second heat exchange channel respectively and exchange heat with the first power module and the second power module respectively, so that both the first power module and the second power module can obtain good heat exchange effects.

[0008] In one embodiment, the flow rate of the heat exchange medium in the first heat exchange channel is equal to the flow rate of the heat exchange medium in the second heat exchange channel.

[0009] In the heat exchange component of the embodiment of the present application, after the heat exchange medium flowing out of the inlet channel is evenly divided into two streams, the two streams of heat exchange medium flow into the first heat exchange channel and the second heat exchange channel respectively, so that the flow rate of the heat exchange medium for heat exchange with the first power module and the second power module is the same, the heat exchange effects received by the first power module and the second power module are the same or not much different, so that the power modules in the controller are evenly heat exchanged.

[0099] With energy depletion and pollution becoming increasingly severe, electric vehicles are becoming increasingly popular. Electric vehicles typically include a controller that independently controls two motors to improve vehicle efficiency and thus range. This controller typically houses two power modules, but these two modules cannot achieve optimal heat exchange simultaneously, severely impacting controller performance.

[0100] The applicant found that one of the main reasons why the two power modules of the controller cannot obtain good heat exchange effects at the same time is that the two power modules are placed in parallel in the controller, causing the controller to occupy a large space in the horizontal direction; in order to alleviate the problem of the large space occupied by the controller in the horizontal direction, a method of arranging the two power modules up and down is proposed, and a heat exchange channel is provided between the two power modules. The heat exchange medium flows in the heat exchange channel to realize heat exchange between the two power modules, but the heat exchange medium first flows through one of the power modules and then flows through the other power module. This results in one of the two power modules having a relatively good heat exchange effect and the other power module having a relatively poor heat exchange, causing the two power modules to not obtain good heat exchange effects at the same time.

[0101] In order to simultaneously improve the heat exchange effect of the two power modules, the applicant has designed a heat exchange component after in-depth research. The heat exchange component is provided with two parallel first heat exchange channels and second heat exchange channels. This design allows the first heat exchange channel and the second heat exchange channel to perform separate heat exchange on the first power module and the second power module respectively, thereby ensuring that the first power module and the second power module can obtain good heat exchange effects at the same time.

[0102] The heat exchange components, housing, controller, and drive device disclosed in the embodiments of the present application can be used, but are not limited to, in electric equipment such as vehicles, ships, or aircraft; by using a power system composed of the heat exchange components, housing, controller, and drive device disclosed in the present application, it is beneficial to improve the performance of the power system.

[0103] The electric devices provided in the embodiments of the present application may also be, but are not limited to, electric toys, electric tools, battery vehicles, electric vehicles, ships, spacecraft, etc. Among them, electric toys may include fixed or mobile electric toys, such as game consoles, electric vehicle toys, electric ship toys, and electric airplane toys, etc. Spacecraft may include airplanes, rockets, space shuttles, and spacecraft, etc.

[0104] For the convenience of description, the following embodiments are described by taking the electric device as a vehicle as an example.

[0106] The vehicle 1000 may further include a controller 1200 and a motor 1300 . The controller 1200 is used to control the battery 1100 to supply power to the motor 1300 , for example, to meet the power requirements of the vehicle 1000 during startup, navigation, and driving.

During this process, the first power module 201 absorbs the heat of the heat exchange medium, thereby realizing the heating of the first power module 201.

[0117] The second heat exchange channel 131 refers to the channel for the flow of the heat exchange medium in the second heat exchange element 130; wherein the second heat exchange element 130 is made of a material with good thermal conductivity such as aluminum and copper; the heat exchange of the second power module 202 can refer to the heating of the second power module 202, or it can refer to the cooling of the second power module 202; wherein, when the temperature of the heat exchange medium flowing into the second heat exchange channel 131 is lower than the temperature of the second power module 202, during the flow of the heat exchange medium in the second heat exchange channel 131, the heat emitted by the second power module 202 will be transferred to the heat exchange medium through the second heat exchange element 130, and the heat exchange medium After absorbing heat, the heat exchange medium flows out of the second heat exchange channel 131, thereby taking away the heat of the second power module 202, thereby realizing the cooling of the second power module 202; when the temperature of the heat exchange medium flowing into the second heat exchange channel 131 is higher than the temperature of the second power module 202, during the flow of the heat exchange medium in the second heat exchange channel 131, the heat emitted by the heat exchange medium will be transferred to the second power module 202 through the second heat exchange element 130, and the heat exchange medium releases the heat and flows out of the second heat exchange channel 131. During this process, the second power module 202 absorbs the heat of the heat exchange medium, thereby realizing the heating of the second power module 202.

[0118] The first heat exchange channel 121 connects the inflow channel 141 and the outflow channel 151. It can be understood that the heat exchange medium flows into the first heat exchange channel 121 from the inflow channel 141, exchanges heat with the first power module 201 while flowing in the first heat exchange channel 121, and finally flows out from the outflow channel 151, thereby realizing heat exchange of the first power module 201; wherein, the flow direction of the heat exchange medium can refer to the flow direction indicated by the hollow arrow in Figure 9.

One stream of heat exchange medium flows into the first heat exchange channel 121, and the other stream of heat exchange medium flows into the second heat exchange channel 131. Then, the two streams of heat exchange medium flow into the outflow channel 151 and merge, and finally flow out of the outflow channel 151 together. The two streams of heat exchange medium respectively exchange heat with the first power module 201 and the second power module 202. In this way, the first power module 201 and the second power module 202 can each be heat-exchanged separately, so that the first power module 201 and the second power module 202 can simultaneously obtain good heat exchange effects. The heat exchange medium can be a flowing medium with good heat exchange effects, such as water, air, or heat exchange liquid.

After flowing out of the second inlet section 12122, the heat exchange medium impacts the first power module 201 at a certain angle, forming a uniform flow field within the first heat exchange chamber 1211, so that the first power module 201 can obtain a uniform heat exchange effect, thereby achieving a better heat exchange effect. For example, the angle α can be 30°, 32°, 34°, 36°, 38°, 40°, 42°, 44°, 46°, 48°, 50°, 52°, 54°, 56°, 58°, or 60°. In one embodiment, the angle α is 45°.

[0167] In another embodiment of the present application, the volume of the first heat exchange channel 121 of the heat exchange component 100 is V1, the volume of the second heat exchange channel 131 is V2, and

[0168] The volume V1 of the first heat exchange channel 121 refers to the volume of the heat exchange medium that the first heat exchange channel 121 can accommodate.

[0169] The volume V2 of the second heat exchange channel 131 refers to the volume of the heat exchange medium that the second heat exchange channel 131 can accommodate.

[0170] It can be understood that the volume V1 of the first heat exchange channel 121 and the volume V2 of the second heat exchange channel 131 are not much different, so that the heat exchange medium flowing out of the inlet channel 141 is almost evenly divided into two streams and flows into the first heat exchange channel 121 and the second heat exchange channel 131 respectively. In this way, the heat exchange medium flowing into the first heat exchange channel 121 and the second heat exchange channel 131 is similar, so that the first power module 201 and the second power module 202 obtain the same or similar heat exchange effect, so that the first power module 201 and the second power module 202 can both obtain good heat exchange effect, and the power modules in the heat exchange assembly 100 are uniformly heat exchanged.

[0171] In one embodiment, It can be equal to -0.2, -0.15, -0.1, -0.05, 0, 0.05, 0.01, 0.15 or 0.2.

[0172] In another embodiment, In this way, the difference between the volume V1 of the first heat exchange channel 121 and the volume V2 of the second heat exchange channel 131 is smaller, and the difference between the heat exchange medium flowing into the first heat exchange channel 121 and the second heat exchange channel 131 is smaller, so that the heat exchange difference between the first power module 201 and the second power module 202 is smaller.

[0173] In another embodiment of the present application, the structure of the first heat exchange channel 121 of the heat exchange assembly 100 is the same as the structure of the second heat exchange channel 131 .

[0174] It should be noted that the structure of the first heat exchange channel 121 is the same as that of the second heat exchange channel 131 , which may mean that the structure of the first heat exchange channel 121 is completely identical or substantially the same as that of the second heat exchange channel 131 .

[0175] In the heat exchange component 100 of the embodiment of the present application, since the structure of the first heat exchange channel 121 is the same as that of the second heat exchange channel 131, the heat exchange medium flowing into the channel 141 and out of the channel can be evenly divided into two streams and then flow into the first heat exchange channel 121 and the second heat exchange channel 131 respectively. At the same time, the flow mode of the heat exchange medium in the first heat exchange channel 121 is the same as the flow mode of the heat exchange medium in the second heat exchange channel 131, so that the first power module 201 and the second power module 202 obtain the same or similar heat exchange effect, so that the first power module 201 and the second power module 202 can both obtain good heat exchange effect, and the power modules in the heat exchange component 100 obtain uniform heat exchange; in addition, the structure of the first heat exchange channel 121 and the structure of the second heat exchange channel 131 are the same, so the first heat exchange element 120 and the second heat exchange element 130 can adopt the same structure, thereby improving the versatility of the components and facilitating the processing and manufacturing of the heat exchange component 100.

It can be understood that the distance between the center line AA and the first heat exchange element 120 is the same as the distance between the center line AA and the second heat exchange element 130.

In addition, the first power module 201 is installed on the side of the first heat exchanger 120 facing away from the second heat exchanger 130, and the second power module 202 is installed on the side of the second heat exchanger 130 facing away from the first heat exchanger 120. The first power module 201 and the second power module 202 can both obtain the same or similar heat exchange, thereby ensuring that the first power module 201 and the second power module 202 can both have good heat exchange effects. At the same time, in this installation method, the first power module 201, the first heat exchanger 120, the second heat exchanger 130 and the second power module 202 are stacked along the height direction of the main body 110, and the structure of the entire controller 1200 is compact, which is conducive to reducing the external dimensions of the controller 1200.

[0182] In another embodiment of the present application, as shown in FIG. 7 , FIG. 8 and FIG. 9 , an accommodating space 1001 is formed between the first heat exchange component 120 and the second heat exchange component 130 of the heat exchange assembly 100 .

[0183] Accommodation space 1001 refers to the cavity formed between first heat exchange element 120 and second heat exchange element 130. As shown in FIG9 , first heat exchange element 120 and second heat exchange element 130 are arranged with spacing along the height direction (see the Z direction) of body 110, thereby forming a separation space between first heat exchange element 120 and second heat exchange element 130, which provides space for accommodation space 1001.

[0184] In a specific application, the heat exchange assembly 100 of the embodiment of the present application can install the thin film capacitor 203, circuit board and other electronic components of the controller 1200 in the accommodating space 1001 located between the first heat exchange member 120 and the second heat exchange member 130. On the one hand, the first heat exchange member 120 and the second heat exchange member 130 can be used to exchange heat for the thin film capacitor 203, circuit board and other electronic components to improve the performance of the controller 1200; on the other hand, the thin film capacitor 203, circuit board and other electronic components are located between the first heat exchange member 120 and the second heat exchange member 130, the structure is highly integrated, and the space utilization rate in the heat exchange assembly 100 is high, which is conducive to reducing the volume of the controller 1200.

[0186] The inner cavity of the main body 110, as shown in Figures 6, 7 and 8, refers to a cavity structure that runs through the main body 110 along the height direction of the main body 110 (refer to the Z direction). The partition 160 is horizontally arranged in the inner cavity of the main body 110, thereby dividing the inner cavity of the main body 110 into an upper cavity and a lower cavity, wherein the upper cavity is the first cavity 111 and the lower cavity is the second cavity 112. It should be noted here that cover plates can also be provided at both ends of the main body 110, and the cover plates seal the inner cavity of the main body 110, thereby protecting the components in the main body 110. Of course, in other embodiments, no cover plates are provided at both ends of the main body 110, and the specific selection can be made according to actual needs, and is not limited here.

[0187] The first heat exchanger 120 and the second heat exchanger 130 are both connected to the partition 160. It is understood that the partition 160 serves as a mounting base for the first and second heat exchangers 120 and 130, providing stable support for the first and second heat exchangers 120 and 130, thereby ensuring reliable fixation of the first and second heat exchangers 120 and 130. Furthermore, in specific applications, the first and second power modules 201 and 202 are separately disposed within the first and second half chambers 111 and 112, reducing the mutual influence between the first and second power modules 201 and 202, thereby improving the performance of the controller 1200.

[0188] In another embodiment of the present application, in combination with Figures 6, 7 and 8, the partition 160 of the heat exchange assembly 100 is provided with a mounting hole connecting the first half chamber 111 and the second half chamber 112, the second heat exchange element 130 is installed in the mounting hole, and the first heat exchange element 120 is connected to the second heat exchange element 130.

[0189] The mounting hole refers to a hole structure on the partition 160 for accommodating the second heat exchange element 130. For example, the mounting hole can be a hole structure on the partition 160 that passes through the partition 160 along the height direction of the body 110. Alternatively, as shown in Figure 11, the second heat exchange element 130 and the partition 160 form an integrated structure, so that the second heat exchange element 130 completely fills the mounting hole. In this case, the space occupied by the second heat exchange element 130 on the partition 160 serves as the mounting hole.

[0190] In the heat exchange assembly 100 of the embodiment of the present application, the second heat exchange component 130 is installed in the mounting hole, and the second heat exchange component 130 and the partition 160 are overlapped in the height direction of the main body 110, and the structure is compact; in addition, the partition 160 can also play a stabilizing supporting role for the second heat exchange component 130 and the first heat exchange component 120, and the overall structural strength is good.

[0191] In another embodiment of the present application, in combination with Figures 6, 7 and 8, the heat exchange component 100 provided further includes a first connecting member 170 and a second connecting member 180; the first connecting member 170 is connected between the side portions of the first heat exchange member 120 and the second heat exchange member 130 located on the same side, and the second connecting member 180 is connected between the side portions on the other side of the first heat exchange member 120 and the second heat exchange member 130; the surfaces of the first connecting member 170 and the second connecting member 180 facing each other and the surfaces of the first heat exchange member 120 and the second heat exchange member 130 facing each other are enclosed to form an accommodating space 1001.

[0192] The first connecting member 170 , as shown in FIG. 9 , is a member connected between the left side of the first heat exchange member 120 and the left side of the second heat exchange member 130 .

[0193] The second connecting member 180 , as shown in FIG. 9 , is a member connected between the right side of the first heat exchange member 120 and the right side of the second heat exchange member 130 .

[0194] The first connecting member 170 is connected between the side portions of the first heat exchange member 120 and the second heat exchange member 130 on the same side, and the second connecting member 180 is connected between the side portions of the first heat exchange member 120 and the second heat exchange member 130 on the other side. For example, as shown in FIG9 , the first connecting member 170 is connected between the left side portion of the first heat exchange member 120 and the left side portion of the second heat exchange member 130; the second connecting member 180 is connected between the right side portion of the first heat exchange member 120 and the right side portion of the second heat exchange member 130. In other words, the first connecting member 170 and the second connecting member 180 are spaced apart from each other, and the opposite sides of the first heat exchange member 120 are connected to the first connecting member 170 and the second connecting member 180 respectively. The opposite sides of the first heat exchange member 120 can be stably supported and fixed, and the first heat exchange member 120 is stably fixed and reliable in the heat exchange assembly 100.

[0195] The surfaces of the first connecting member 170 and the second connecting member 180 facing each other and the surfaces of the first heat exchange member 120 and the second heat exchange member 130 facing each other are enclosed to form an accommodating space 1001. It can be understood that, in conjunction with FIG9 , the first heat exchange member 120 and the second heat exchange member 130 are arranged vertically, and the first connecting member 170 and the second connecting member 180 are arranged horizontally. The left side of the first connecting member 170, the right side of the second connecting member 180, the upper side of the second heat exchange member 130 and the lower side of the first heat exchange member 120 are jointly enclosed to form the accommodating space 1001. The accommodating space 1001 is formed by the first connecting member 170, the second connecting member 180, the first heat exchange member 120 and the second heat exchange member 130, without the need for other components. The structure of the heat exchange assembly 100 is simple and convenient for processing and manufacturing.

[0196] In the heat exchange assembly 100 of the embodiment of the present application, the first heat exchange element 120 has a good supporting and fixing effect in the heat exchange assembly 100, which can ensure that the first power module 201 obtains stable and reliable heat exchange; in addition, the heat exchange assembly 100 has a simple structure and is easy to process and manufacture.

[0197] In another embodiment of the present application, in combination with Figures 9 and 10, the first connecting member 170 of the provided heat exchange component 100 is configured with a first connecting channel 171, which is connected to the inlet channel 141, and the second connecting member 180 is configured with a second connecting channel 181, which is connected to the outflow channel 151; the first connecting channel 171 connects one end of the first heat exchange channel 121 and one end of the second heat exchange channel 131; the second connecting channel 181 connects the other end of the first heat exchange channel 121 and the other end of the second heat exchange channel 131.

[0198] The first communication channel 171 refers to a channel structure formed in the first connecting member 170 . For example, as shown in FIG. 9 and FIG. 10 , the first communication channel 171 penetrates the first connecting member 170 along the height direction of the body 110 .

[0199] The second communication channel 181 refers to a channel structure formed in the second connecting member 180 . For example, as shown in FIG. 9 and FIG. 10 , the second communication channel 181 penetrates the first connecting member 170 along the height direction of the body 110 .

[0200] The first connecting channel 171 connects one end of the first heat exchange channel 121 with one end of the second heat exchange channel 131; the second connecting channel 181 connects the other end of the first heat exchange channel 121 with the other end of the second heat exchange channel 131. It can be understood that, as shown in Figures 9 and 10, the two ends of the first connecting channel 171 are connected to the left ends of the first heat exchange channel 121 and the second heat exchange channel 131, respectively, and the two ends of the second connecting channel 181 are connected to the right ends of the first heat exchange channel 121 and the second heat exchange channel 131, respectively. During heat exchange, the heat exchange medium flows from the inlet channel 141 into the first connecting channel 171, is then divided into two streams by the first connecting channel 171, and flows into the first heat exchange channel 121 and the second heat exchange channel 131 respectively. Finally, the two streams of heat exchange medium flow into the second connecting channel 181, merge, and then flow out of the outflow channel 151, thereby achieving heat exchange between the first power module 201 and the second power module 202.

[0201] The heat exchange assembly 100 of the embodiment of the present application utilizes the first connecting channel 171 formed in the first connecting member 170 to enable the inflow channel 141 to be simultaneously connected to the first heat exchange channel 121 and the second heat exchange channel 131. Similarly, the second connecting channel 181 formed in the second connecting member 180 is utilized to enable the outflow channel 151 to be simultaneously connected to the first heat exchange channel 121 and the second heat exchange channel 131. On the one hand, the internal space of the first connecting member 170 and the second connecting member 180 can be fully utilized, which is beneficial to reducing the volume of the heat exchange assembly 100; on the other hand, there is no need to set up other connecting structures, which is beneficial to reducing the number of parts of the heat exchange assembly 100 and reducing the production cost.

[0202] In another embodiment of the present application, in combination with Figure 9, the first connecting member 170 of the heat exchange component 100 is configured with a first connecting hole 172, and the second connecting member 180 is configured with a second connecting hole 182; the first connecting hole 172 connects the inflow channel 141 and the first connecting channel 171, and the second connecting hole 182 connects the outflow channel 151 and the second connecting channel 181, and the first connecting hole 172 and the second connecting hole 182 are centrally symmetrical; the first heat exchange channel 121 and the second heat exchange channel 131 are centrally symmetrical or axially symmetrical, and the first connecting channel 171 and the second connecting channel 181 are centrally symmetrical or axially symmetrical.

[0203] The first connecting hole 172 refers to a hole structure provided on the first connecting member 170 and used to connect the inflow channel 141 and the first heat exchange channel 121 .

[0204] The second connecting hole 182 refers to a hole structure provided on the second connecting member 180 and used to connect the outflow channel 151 and the second heat exchange channel 131 .

[0205] The first connecting hole 172 and the second connecting hole 182 are centrally symmetrical; it can be understood that the first connecting hole 172 coincides with the second connecting hole 182 after rotating 180° around the center point of the accommodating space 1001; of course, it is also possible that the second connecting hole 182 coincides with the first connecting hole 172 after rotating 180° around the center point of the accommodating space 1001.

[0206] The first heat exchange channel 121 and the second heat exchange channel 131 are centrally symmetrical. It can be understood that the first heat exchange channel 121 coincides with the second heat exchange channel 131 after rotating 180° around the center point of the accommodating space 1001; of course, it is also possible that the second heat exchange channel 131 coincides with the first heat exchange channel 121 after rotating 180° around the center of the accommodating space 1001, that is, the first heat exchange channel 121 and the second heat exchange channel 131 have the same structure.

[0207] The first communicating channel 171 and the second communicating channel 181 are centrally symmetrical. It can be understood that the first communicating channel 171 coincides with the second communicating channel 181 after being rotated 180 degrees around the center point of the accommodating space 1001; of course, it is also possible that the second communicating channel 181 coincides with the first communicating channel 171 after being rotated 180 degrees around the center point of the accommodating space 1001, that is, the first communicating channel 171 and the second communicating channel 181 have the same structure.

[0208] The center point of the accommodating space 1001 refers to the equidistant point to the first heat exchange member 120, the second heat exchange member 130, the first connecting member 170 and the second connecting member 180. For example, in combination with Figure 9, the center point of the accommodating space 1001 can be point C as shown in Figure 9, where point C refers to the intersection between line AA and line BB.

[0209] The first heat exchange channel 121 and the second heat exchange channel 131 are axially symmetrical. For example, as shown in FIG. 9 , the first heat exchange channel 121 and the second heat exchange channel 131 are symmetrical about line AA, that is, the first heat exchange channel 121 and the second heat exchange channel 131 have the same structure.

[0210] The first communication channel 171 and the second communication channel 181 are axially symmetrical. For example, as shown in FIG. 9 , the first communication channel 171 and the second communication channel 181 are symmetrical about line BB; that is, the first communication channel 171 and the second communication channel 181 have the same structure.

[0211] In the heat exchange assembly 100 of the embodiment of the present application, the heat exchange medium flowing out of the inflow channel 141 is divided into two streams after passing through the first connecting hole 172 and the first connecting channel 171. The two streams of heat exchange medium flow into the first heat exchange channel 121 and the second heat exchange channel 131 respectively and exchange heat with the first power module 201 and the second power module 202, and then merge through the second connecting channel 181 and finally flow into the outflow channel 151; and since the first connecting hole 172 and the second connecting hole 182 are symmetrical about the center of the accommodating space 1001; the first heat exchange channel 121 and the second heat exchange channel 131 are symmetrical about the center of the accommodating space 1001 Symmetrical or axisymmetric, the first connecting channel 171 and the second connecting channel 181 are symmetrical or axisymmetric about the center of the accommodating space 1001. Therefore, the space through which the two heat exchange media flow is the same, so that the heat exchange medium flowing out of the inlet channel 141 will be evenly divided into two streams, and the flow fields of the two heat exchange media in the first heat exchange channel 121 and the second heat exchange channel 131 are the same or have little difference, and the heat exchange effects received by the first power module 201 and the second power module 202 are the same or have little difference, so that the first power module 201 and the second power module 202 can both receive good heat exchange effects.

[0212] In another embodiment of the present application, as shown in FIG. 9 , the first connecting hole 172 of the heat exchange assembly 100 is located in the middle of the first connecting channel 171 , and the second connecting hole 182 is located in the middle of the second connecting channel 181 .

[0213] The first connecting hole 172 is located in the middle position of the first connecting channel 171. It can be understood that, in combination with Figure 9, in the height direction of the first connecting member 170, the first connecting hole 172 is located in the middle of the first connecting member 170; that is, the spacing between the first connecting hole 172 and the first heat exchange member 120 is the same as the spacing between the first connecting hole 172 and the second heat exchange member 130.

[0214] The second connecting hole 182 is located in the middle position of the second connecting channel 181. It can be understood that, in combination with Figure 9, in the height direction of the second connecting member 180, the second connecting hole 182 is located in the middle of the second connecting member 180; that is, the spacing between the second connecting hole 182 and the first heat exchange member 120 is the same as the spacing between the second connecting hole 182 and the second heat exchange member 130.

[0215] In the heat exchange assembly 100 of the embodiment of the present application, the heat exchange medium flowing out of the first connecting hole 172 can be divided into two streams, and the two streams of heat exchange medium flow toward the two ends of the first connecting channel 171 respectively to flow into the first heat exchange channel 121 and the second heat exchange channel 131 respectively. Similarly, one stream of heat exchange medium flowing out of the first heat exchange channel 121 and the other stream of heat exchange medium flowing out of the second heat exchange channel 131 both flow toward the middle of the second connecting channel 181, and finally merge in the second connecting hole 182 and flow into the outflow channel 151. In this way, the heat exchange medium can be evenly distributed. It is divided into two streams, and the flow fields of the two streams of heat exchange medium in the first heat exchange channel 121 and the second heat exchange channel 131 are the same or have little difference, and the heat exchange effects received by the first power module 201 and the second power module 202 are the same or have little difference, so that the first power module 201 and the second power module 202 both receive good heat exchange effects; in addition, the first connecting hole 172 is located in the middle position of the first connecting channel 171, and the second connecting hole 182 is located in the middle position of the second connecting channel 181, which also facilitates the processing and manufacturing of the heat exchange component 100.

[0216] In another embodiment of the present application, in combination with Figure 9, the heat exchange component 100 provided further includes a first seal 204 and a second seal 205. The first seal 204 is clamped between the first connecting member 170 and the first heat exchange member 120, and the first seal 204 can seal the connection between the first connecting channel 171 and the first heat exchange channel 121; the second seal 205 is clamped between the second connecting member 180 and the first heat exchange member 120, and the second seal 205 can seal the connection between the second connecting channel 181 and the first heat exchange channel 121.

[0217] The first seal 204 refers to a sealing component clamped between the first connector 170 and the first heat exchanger 120. For example, the first seal 204 can be deformed by the clamping force between the first connector 170 and the first heat exchanger 120 to fill the gap between the first connector 170 and the first heat exchanger 120, thereby preventing the heat exchange medium from leaking from the gap between the first connector 170 and the first heat exchanger 120, thereby achieving sealing of the connection between the first connecting channel 171 and the first heat exchange channel 121.

[0218] In one embodiment, as shown in Figures 9 and 10, the first seal 204 is clamped between the first heat exchange member 120 and the first connecting member 170. The first seal 204 is arranged around the opening of the first connecting channel 171. The heat exchange medium flowing out of the first connecting channel 171 passes through the inner hole of the first seal 204 and flows into the first heat exchange channel 121.

[0224] In another embodiment of the present application, in combination with Figures 9 and 10, the heat exchange assembly 100 provided also includes an inlet pipe 140 and an outlet pipe 150, the inlet pipe 140 is constructed with an inlet channel 141, and the outflow pipe 150 is constructed with an outflow channel 151.

[0227] An inflow channel 141 is constructed in the inflow pipe 140. For example, as shown in FIG9 , the inner hole of the inflow pipe 140 serves as the inflow channel 141. Furthermore, by directly utilizing the inner hole of the inflow pipe 140 as the inflow channel 141, the inflow channel 141 is easily manufactured, facilitating the manufacture of the heat exchange assembly 100.
