Description

[0002] In recent years, power device modules have been widely used in new energy vehicles, switching power supplies, and autonomous driving. With the rapid development of electronics and high-power semiconductor manufacturing technologies, the operating voltage, current, and output power of power modules have continued to increase, while the output frequency has become increasingly higher and the physical size has become smaller. This has led to an increasing temperature rise during operation. If the heat generated cannot be dissipated in a timely manner, it will directly affect the normal operation of the power module.

[0003] However, the heat exchange efficiency between the heat dissipation medium in the current heat dissipation assembly and the heating elements in the electronically controlled power module is poor during flow, resulting in poor heat dissipation effect of the heat dissipation assembly on the heating elements.

[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0055] This application provides a heat dissipation component, please refer to Figure 1 、 Figure 2 and Figure 8 One side of the heat dissipation component 1 is used to set the heating element 2, and a first heat dissipation channel 11 and a second heat dissipation channel 12 are formed in the heat dissipation component 1. The first heat dissipation channel 11 is used to allow the first heat dissipation medium to flow, and the second heat dissipation channel 12 is used to allow the second heat dissipation medium to flow, so that at least one of the first heat dissipation medium and the second heat dissipation medium can exchange heat with the heating element 2, and the first heat dissipation medium can exchange heat with the second heat dissipation medium.

[0056] Specifically, heat dissipation assembly 1 serves as a heat dissipation structure for heating element 2. Two independent heat dissipation channels are formed within heat dissipation assembly 1, each channel providing a different heat dissipation medium. When a first heat dissipation medium and a second heat dissipation medium flow within heat dissipation assembly 1, at least one of the first heat dissipation medium and the second heat dissipation medium is used to exchange heat with heating element 2 to remove heat generated during operation. Simultaneously, heat exchange can also occur between the first heat dissipation medium and the second heat dissipation medium to remove heat from heating element 2 that has been absorbed by one of the heat dissipation media. This improves the heat dissipation efficiency of heat dissipation assembly 1 for heating element 2 and ensures stable operation of heating element 2.

[0057] In some embodiments, the heat dissipation assembly 1 includes a first heat dissipation element 13 and a second heat dissipation element 14 arranged opposite each other along a first direction X. The first heat dissipation element 13 is connected to the second heat dissipation element 14. The side of the first heat dissipation element 13 facing away from the second heat dissipation element 14 is used to accommodate the heating element 2. A first heat dissipation channel 11 is formed in the first heat dissipation element 13, and a second heat dissipation channel 12 is formed in the second heat dissipation element 14. That is, the first heat dissipation element 13 and the second heat dissipation element 14 are stacked along the thickness direction of the heat dissipation assembly 1. The heating element 2 is disposed on the surface of the first heat dissipation element 13. The first heat dissipation channel 11 on the first heat dissipation element 13 is used to allow a first heat dissipation medium to flow. The first heat dissipation medium is used to exchange heat with the heating element 2 to remove heat generated during operation of the heating element 2.

[0058] The second heat dissipation channel 12 on the second heat dissipation member 14 is used for flowing a second heat dissipation medium, and the second heat dissipation medium is used to perform heat exchange with the first heat dissipation medium to remove the heat of the heating element 2 absorbed by the first heat dissipation medium, so that the first heat dissipation medium can absorb more heat generated by the heating element 2, thereby improving the heat exchange efficiency between the first heat dissipation medium and the heating element 2, and further improving the heat dissipation efficiency of the heat dissipation assembly 1 to the heating element 2, thereby ensuring the stable operation of the heating element 2.

[0059] It should be noted that since the heating element 2 is arranged on the first heat sink 13 and the second heat sink 14 is directly connected to the first heat sink 13, the heat generated by the heating element 2 can also be transferred to the second heat sink 14 through the connection between the second heat sink 14 and the first heat sink 13, so that the second heat dissipation medium can also take away part of the heat during the flow process, thereby improving the heat dissipation efficiency of the heat dissipation assembly 1 to the heating element 2.

[0060] In some embodiments, the heat dissipation assembly 1 includes a first inlet 141 and a first transition section 142. The first transition section 142 connects the first inlet 141 with the first heat dissipation channel 11. The conduction direction of the first transition section 142 forms an acute angle with the first direction X. That is, the first transition section 142 is a sloped channel. By providing the inclined first transition section 142 between the first inlet 141 and the first heat dissipation channel 11, the first heat dissipation medium can change its flow direction through the first transition section 142 after flowing into the first inlet 141. Compared to flowing straight into the first heat dissipation channel 11 from the first inlet 141, the provision of the first transition section 142 enables the first heat dissipation medium to fully cover the first heat dissipation channel 11, thereby ensuring heat exchange efficiency between the first heat dissipation medium and the heating element 2.

[0061] Among them, the first transition section 142 can be tilted from bottom to top or from top to bottom. Its specific tilting method can be designed and adjusted according to actual needs and the specific structure of the first heat sink 13 and the second heat sink 14, and is not specifically limited here.

[0062] In some examples, the first inlet 141 is disposed on a sidewall of the second heat sink 14, and the first transition section 142 is disposed within the second heat sink 14. Specifically, the second heat sink 14 is connected to the first heat sink 13 and is used to seal the first heat dissipation channel 11 on the first heat sink 13. By disposing the first inlet 141 and the first transition section 142 on the second heat sink 14, the placement of the first transition section 142 is more flexible and can be adjusted based on the specific structure of the first heat dissipation channel 11 within the first heat sink 13, facilitating adjustment of the placement and inclination angle of the first transition section 142.

[0063] It should be noted that the first inlet 141 and the first transition section 142 can also be disposed within the first heat sink 13. That is, the first heat sink 13 can wrap around the sidewall of the second heat sink 14, and the first inlet 141 and the first transition section 142 are disposed in the portion where the first heat sink 13 wraps around the sidewall of the second heat sink 14, to facilitate the design of the angle of the first transition section 142. The specific arrangement of the first inlet 141 and the first transition section 142 can be selected and adjusted according to actual design requirements and is not specifically limited here.

[0064] In some examples, a first confluence groove 131 is formed on the side of the first heat sink 13 facing the second heat sink 14. The first confluence groove 131 connects the first transition section 142 and the first heat dissipation channel 11. The first confluence groove 131 extends along a second direction Y, which forms an angle with the first direction X. That is, the first confluence groove 131 has a strip-shaped structure. When the first heat dissipation medium flows through the first inlet 141 to the first transition section 142, it first converges in the first confluence groove 131 and then flows from the first confluence groove 131 into the first heat dissipation channel 11. Due to the strip-shaped first confluence groove 131, the first heat dissipation medium can fully cover the first heat dissipation channel 11 when flowing from the first confluence groove 131 to the first heat dissipation channel 11, thereby ensuring heat exchange efficiency between the first heat dissipation medium and the heating element 2.

[0065] It should be noted that, in the embodiment of the present application, a plurality of columns may be provided on the side of the first heat sink 13 facing the second heat sink 14, and a first heat dissipation channel 11 (such as Figure 3 As shown), the extension length of the first confluence groove 131 can be adjusted according to the distribution length of the column in the second direction Y. It is only necessary to ensure that the length of the first confluence groove 131 in the second direction Y is greater than or equal to the distribution length of the column in the second direction Y to ensure that the first heat dissipation medium can fully cover the first heat dissipation channel 11. No special limitation is made here.

[0066] In some embodiments, the heat dissipation assembly 1 includes a first outlet 143 and a second transition section 144. The second transition section 144 connects the first heat dissipation channel 11 and the first outlet 143. The conduction direction of the second transition section 144 forms an acute angle with the first direction X. That is, the second transition section 144 is a sloped channel. By providing the inclined second transition section 144 between the first heat dissipation channel 11 and the first outlet 143, the first heat dissipation medium can change its flow direction through the second transition section 144 after flowing out of the first heat dissipation channel 11. Compared to flowing out of the first heat dissipation channel 11 in a straight line, the provision of the second transition section 144 can prevent the first heat dissipation medium from being deposited in the first heat dissipation channel 11, facilitate the discharge of the first heat dissipation medium, and thus help improve the circulation stability of the first heat dissipation medium.

[0067] Among them, the second transition section 144 can be tilted from bottom to top or from top to bottom. Its specific tilting method can be designed and adjusted according to actual needs and the specific structure of the first heat sink 13 and the second heat sink 14, and is not specifically limited here.

[0068] In some examples, the first outlet 143 is provided on a side wall of the second heat sink 14, and the second transition section 144 is provided within the second heat sink 14. That is, the second heat sink 14 is connected to the first heat sink 13 and is used to seal the first heat dissipation channel 11 on the first heat sink 13. By providing the first outlet 143 and the second transition section 144 on the second heat sink 14, the arrangement of the second transition section 144 is more flexible and can be adjusted according to the specific structure of the first heat dissipation channel 11 within the first heat sink 13, facilitating adjustment of the location and inclination angle of the second transition section 144.

[0069] It should be noted that the first outlet 143 and the second transition section 144 can also be disposed within the first heat sink 13. That is, the first heat sink 13 can wrap around the sidewall of the second heat sink 14, and the first outlet 143 and the second transition section 144 are disposed in the portion where the first heat sink 13 wraps around the sidewall of the second heat sink 14, to facilitate the design of the angle of the second transition section 144. The specific arrangement of the first outlet 143 and the second transition section 144 can be selected and adjusted according to actual design requirements and is not specifically limited here.

[0070] In some examples, a second confluence groove 132 is formed on the side of the first heat sink 13 facing the second heat sink 14. The second confluence groove 132 connects the second transition section 144 and the first heat dissipation channel 11. The second confluence groove 132 extends along a second direction Y, which forms an angle with the first direction X. That is, the second confluence groove 132 has a strip-shaped structure. After the first heat dissipation medium flows out of the first heat dissipation channel 11, it first converges in the second confluence groove 132 and then flows from the second confluence groove 132 through the second transition section 144 to the first outlet 143, facilitating the discharge of the first heat dissipation medium, thereby helping to improve the circulation stability of the first heat dissipation medium.

[0071] In some examples, a serpentine heat dissipation channel may be provided on the side of the second heat dissipation element 14 facing away from the first heat dissipation element 13. Figure 4 The second heat dissipation channel 12 can be formed by four serpentine heat dissipation channels connected in parallel, and the four serpentine heat dissipation channels are evenly distributed to improve the heat dissipation uniformity of the second heat dissipation channel 12.

[0072] It should be noted that the specific structure and distribution of the first heat dissipation channel 11 and the second heat dissipation channel 12 in the embodiment of the present application can be designed and adjusted according to actual heat dissipation requirements, and are not specifically limited here.

[0073] In some embodiments, the heat dissipation assembly 1 further includes a third heat dissipation element 15, which is disposed on a side of the second heat dissipation element 14 facing away from the first heat dissipation element 13. The third heat dissipation element 15 is connected to the second heat dissipation element 14 and seals the second heat dissipation channel 12. The third heat dissipation element 15 is provided with a second inlet 151 and a second outlet 152, each of which communicates with the second heat dissipation channel 12. Specifically, the third heat dissipation element 15, the second heat dissipation element 14, and the first heat dissipation element 13 are stacked in the thickness direction of the heat dissipation assembly 1. The second heat dissipation element 14 is used to seal the first heat dissipation channel 11, and the third heat dissipation element 15 is used to seal the second heat dissipation channel 12. By locating the second inlet 151 and the second outlet 152 on the third heat dissipation element 15, the arrangement of the second heat dissipation channel 12 on the second heat dissipation element 14 is more flexible. The positions of the second inlet 151 and the second outlet 152 can be adjusted based on the specific structure of the second heat dissipation channel 12 to meet the heat exchange requirements of the second heat dissipation medium and the first heat dissipation medium.

[0074] In some examples, the second inlet 151 penetrates the third heat dissipation element 15 along the first direction X; and / or the second outlet 152 penetrates the third heat dissipation element 15 along the first direction X. That is, the second inlet 151 and / or the second outlet 152 penetrate the third heat dissipation element 15 along the thickness direction of the third heat dissipation element 15. Compared with providing the second inlet 151 and / or the second outlet 152 on the side wall of the third heat dissipation element 15, the thickness of the third heat dissipation element 15 can be reduced, thereby helping to achieve a lightweight and thin design of the heat dissipation assembly 1 as a whole.

[0075] In some embodiments, see Figure 5 and Figure 6 The heat dissipation assembly 1 includes a fourth heat dissipation member 16 and a fifth heat dissipation member 17 arranged opposite to each other along the first direction X. The side of the fourth heat dissipation member 16 facing away from the fifth heat dissipation member 17 is used to set the heating element 2. The first heat dissipation channel 11 and the second heat dissipation channel 12 are formed in the fourth heat dissipation member 16. The fifth heat dissipation member 17 is connected to the fourth heat dissipation member 16 and seals the first heat dissipation channel 11 and the second heat dissipation channel 12.

[0076] That is, the heat dissipation assembly 1 is formed by the fourth heat dissipation member 16 and the fifth heat dissipation member 17 being fastened together. The first heat dissipation channel 11 and the second heat dissipation channel 12 are simultaneously formed in the fourth heat dissipation member 16, and the first heat dissipation channel 11 and the second heat dissipation channel 12 are independent of each other. When the first heat dissipation medium and the second heat dissipation medium flow in the corresponding heat dissipation channel, they can both be used to exchange heat with the heating element 2 to take away the heat generated by the heating element 2. At the same time, heat exchange can also be performed between the first heat dissipation medium and the second heat dissipation medium, so that one of the heat dissipation media partially takes away the heat of the heating element 2 absorbed by the other heat dissipation medium, thereby improving the heat dissipation effect of the heat dissipation assembly 1 on the heating element 2.

[0077] In some embodiments, the first heat dissipation channel 11 includes a plurality of interconnected first sub-heat dissipation channels 111, and the second heat dissipation channel 12 includes a plurality of interconnected second sub-heat dissipation channels 121. The plurality of first sub-heat dissipation channels 111 and the plurality of second sub-heat dissipation channels 121 are alternately arranged. That is, when the first heat dissipation medium and the second heat dissipation medium flow in the corresponding heat dissipation channels, at least one side of the first heat dissipation medium in each section of the first sub-heat dissipation channel 111 is adjacent to the second heat dissipation medium, and at least one side of the second heat dissipation medium in each section of the second sub-heat dissipation channel 121 is adjacent to the first heat dissipation medium, thereby improving the heat exchange efficiency between the first heat dissipation medium and the second heat dissipation medium, thereby improving the heat dissipation effect of the heat dissipation assembly 1 on the heating element 2.

[0078] For some examples, see Figure 7 The first sub-heat dissipation channel 111 and the second sub-heat dissipation channel 121 extend along a third direction Z, and the plurality of first sub-heat dissipation channels 111 and the plurality of second sub-heat dissipation channels 121 are alternately arranged along a second direction Y. The third direction Z, the second direction Y, and the first direction X form an angle with each other. Specifically, the first heat dissipation channel 11 is formed by a plurality of first sub-heat dissipation channels 111 arranged in a strip shape along the third direction Z, connected in series or in parallel. The second heat dissipation channel 12 is formed by a plurality of second sub-heat dissipation channels 121 arranged in a strip shape along the third direction Z, connected in series or in parallel. By alternating the plurality of first sub-heat dissipation channels 111 and the plurality of second sub-heat dissipation channels 121 along the second direction Y, adjacent first sub-heat dissipation channels 111 and second sub-heat dissipation channels 121 can exchange heat along the entire length direction (the third direction Z), ensuring sufficient heat exchange area between the first heat dissipation medium and the second heat dissipation medium, thereby improving the heat exchange efficiency between the first heat dissipation medium and the second heat dissipation medium.

[0079] For some examples, see Figure 6 and Figure 7 The fourth heat sink 16 has a flow space 161 formed therein. Two spirally extending partitions 162 are disposed within the flow space 161. The two partitions 162 are connected at their ends near the spiral center. The two partitions 162 divide the flow space 161 into a first heat dissipation channel 11 and a second heat dissipation channel 12. The first heat dissipation channel 11 and the second heat dissipation channel 12 each independently extend in a spiral. Specifically, the first heat dissipation channel 11 and the second heat dissipation channel 12 are independent spiral heat dissipation channels. Each circle of the first heat dissipation channel 11 is nested between two circles of the second heat dissipation channel 12, and each circle of the second heat dissipation channel 12 is nested between two circles of the first heat dissipation channel 11. This ensures sufficient heat exchange area between the first and second heat dissipation media, thereby improving the heat exchange efficiency between the first and second heat dissipation media.

[0080] It should be noted that, in the embodiment of the present application, there is no specific limitation on the specific structure and distribution of the first heat dissipation channel 11 and the second heat dissipation channel 12 on the fourth heat dissipation element 16. It is only necessary to ensure that there is sufficient heat exchange area between the first heat dissipation channel 11 and the second heat dissipation channel 12 to ensure the heat exchange efficiency between the first heat dissipation medium and the second heat dissipation medium.

[0081] In some examples, a first outlet 143 and a second outlet 152 are provided on the sidewall of the fourth heat sink 16, and a first inlet 141 and a second inlet 151 are provided on the fifth heat sink 17. The first inlet 141 and the first outlet 143 are respectively connected to the first heat dissipation channel 11, and the second inlet 151 and the second outlet 152 are respectively connected to the second heat dissipation channel 12. By providing the inlet and outlet of the first heat dissipation channel 11 and the inlet and outlet of the second heat dissipation channel 12 on different heat sinks, the flexibility of the arrangement of the first heat dissipation channel 11 and the second heat dissipation channel 12 is increased, thereby meeting the different heat dissipation requirements of the heat dissipation assembly 1.

[0082] Among them, the first inlet 141 and the second inlet 151 respectively penetrate the fifth heat sink 17 along the thickness direction (first direction X) of the fifth heat sink 17, that is, the first heat sink medium and the second heat sink medium respectively enter the first heat sink channel 11 and the second heat sink channel 12 vertically from the side of the fifth heat sink 17 away from the fourth heat sink 16, so that the first heat sink medium and the second heat sink medium can vertically impact the fourth heat sink 16, so as to improve the heat exchange efficiency between the first heat sink medium and the second heat sink medium and the heating element 2; at the same time, setting the first inlet 141 and the second inlet 151 to penetrate the fifth heat sink 17 along the first direction X also facilitates reducing the thickness of the third heat sink 15, thereby helping to achieve a lightweight design of the entire heat dissipation component 1.

[0083] In some embodiments, one of the first heat dissipation medium and the second heat dissipation medium includes a refrigerant, and the other includes a coolant. When the first heat dissipation channel 11 and the second heat dissipation channel 12 are respectively located in the first heat dissipation member 13 and the second heat dissipation member 14, if the first heat dissipation medium is a coolant and the second heat dissipation medium is a refrigerant, the coolant can be used to exchange heat with the heating element 2, and the refrigerant can be used to pre-cool the coolant and remove the heat absorbed by the coolant to improve the heat exchange efficiency between the coolant and the heating element 2; if the first heat dissipation medium is a refrigerant and the second heat dissipation medium is a coolant, the refrigerant's strong heat exchange capacity can be used to directly exchange heat with the heating element 2 to ensure sufficient heat dissipation efficiency for the heating element 2, and the coolant can also be used to remove part of the heat absorbed by the refrigerant to further improve the heat dissipation efficiency for the heating element 2.

[0084] When the first heat dissipation channel 11 and the second heat dissipation channel 12 are both located in the fourth heat dissipation member 16, the refrigerant can utilize its powerful heat exchange capacity to directly exchange heat with the heating element 2, or it can utilize the coolant to directly exchange heat with the heating element 2. At the same time, the refrigerant can also be used to cool the coolant to improve the heat exchange efficiency between the coolant and the heating element 2, thereby improving the overall heat dissipation efficiency of the heat dissipation assembly 1 to the heating element 2.

[0085] An embodiment of the present application also provides an electronically controlled power module, which includes a heat dissipation component. The specific structure of the heat dissipation component refers to the above embodiment. Since the electronically controlled power module in this application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0086] See also Figure 8 The electronically controlled power module 3 includes a heat dissipation component 1 and a heating element 2. The heating element 2 is arranged on the heat dissipation component 1. A heat dissipation flow channel is formed in the heat dissipation component 1. The heat dissipation flow channel is used for allowing the heat dissipation medium to flow to exchange heat with the heating element 2 and take away the heat generated during the operation of the heating element 2, thereby cooling the heating element 2, reducing the temperature of the heating element 2, and ensuring the stable operation of the heating element 2.

[0087] Among them, a first heat dissipation channel 11 and a second heat dissipation channel 12 are formed in the heat dissipation component 1, the first heat dissipation channel 11 is used to flow the first heat dissipation medium, and the second heat dissipation channel 12 is used to flow the second heat dissipation medium, and at least one of the first heat dissipation medium and the second heat dissipation medium is heat-exchanged with the heating element 2, and at the same time, the first heat dissipation medium and the second heat dissipation medium are heat-exchanged. At least one of the first heat dissipation medium and the second heat dissipation medium can be used to dissipate heat for the heating element 2, and the heat exchange between the first heat dissipation medium and the second heat dissipation medium can be used to take away the heat absorbed by the heating element 2, thereby improving the heat dissipation efficiency of the heat dissipation component 1 to the heating element 2 and ensuring the stable operation of the heating element 2.

[0088] It should be noted that one of the first heat dissipation medium and the second heat dissipation medium includes a refrigerant, and the other includes a coolant. When the first heat dissipation channel 11 and the second heat dissipation channel 12 are respectively located in the first heat dissipation member 13 and the second heat dissipation member 14, if the first heat dissipation medium is a coolant and the second heat dissipation medium is a refrigerant, the coolant can be used to exchange heat with the heating element 2, and the refrigerant can be used to pre-cool the coolant and remove the heat absorbed by the coolant to improve the heat exchange efficiency between the coolant and the heating element 2; if the first heat dissipation medium is a refrigerant and the second heat dissipation medium is a coolant, the refrigerant's strong heat exchange capacity can be used to directly exchange heat with the heating element 2 to ensure sufficient heat dissipation efficiency for the heating element 2, and the coolant can also be used to remove part of the heat absorbed by the refrigerant to further improve the heat dissipation efficiency for the heating element 2.

[0089] When the first heat dissipation channel 11 and the second heat dissipation channel 12 are both located in the fourth heat dissipation member 16, the refrigerant can utilize its powerful heat exchange capacity to directly exchange heat with the heating element 2, or it can utilize the coolant to directly exchange heat with the heating element 2. At the same time, the refrigerant can also be used to cool the coolant to improve the heat exchange efficiency between the coolant and the heating element 2, thereby improving the overall heat dissipation efficiency of the heat dissipation assembly 1 to the heating element 2.

[0090] See also Figures 9 to 11 According to the results of thermal simulation calculations, compared with the existing heat dissipation structure and water cooling, the electronically controlled power module 3 in the embodiment of the present application can make the heat dissipation component 1 have a stronger heat dissipation efficiency by utilizing the above-mentioned heat dissipation component 1 and the cooling method of the combination of refrigerant and coolant. The maximum temperature rise of multiple heating elements 2 in the electronically controlled power module 3 is also significantly reduced, which helps to improve the output current value of the electronically controlled power module 3 and expand the scope of use of the electronically controlled power module 3.

[0091] An embodiment of the present application also provides a heat dissipation system, which includes a heat dissipation component or an electronically controlled power module. The specific structure of the heat dissipation component or the electronically controlled power module refers to the above embodiment. Since the heat dissipation system in the present application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0092] In some embodiments, see Figure 12The heat dissipation system 4 also includes a first cooling component 41 and a second cooling component 42. The first cooling component 41 is connected to the heat dissipation component 1 or the heat dissipation component 1 in the electronically controlled power module 3. The first cooling component 41 is used to provide a first heat dissipation medium to the heat dissipation component 1, so that the first heat dissipation medium flows in the first heat dissipation channel 11 of the heat dissipation component 1. The second cooling component 42 is connected to the heat dissipation component 1, and the second cooling component 42 is used to provide a second heat dissipation medium to the heat dissipation component 1, so that the second heat dissipation medium flows in the second heat dissipation channel 12 of the heat dissipation component 1.

[0093] That is, the first heat dissipation medium and the second heat dissipation medium are provided by two independent cooling circuits, so that even when the cooling circuit of one heat dissipation medium fails, the cooling circuit of the other heat dissipation medium can still dissipate heat for the heating element 2, so that the heating element 2 can operate normally.

[0094] In some examples, the first cooling assembly 41 includes a driver 411 and a liquid storage member 412, which are interconnected. The liquid storage member 412 is used to store and provide a first heat dissipation medium, and the driver 411 is used to drive the first heat dissipation medium to flow within the first heat dissipation channel 11. Specifically, the liquid storage member 412 serves as the source of the first heat dissipation medium, storing the first heat dissipation medium and participating in its circulation. The driver 411 serves as the circulating power source for the first heat dissipation medium, driving the first heat dissipation medium to flow out of and into the liquid storage member 412. During the flow process, the first heat dissipation medium exchanges heat with the second heat dissipation medium and the heating element 2 in the electronically controlled power module 3, thereby achieving circulatory cooling of the first heat dissipation medium.

[0095] In some examples, the second cooling assembly 42 includes a compressor 421 and a first heat exchanger 422 that are interconnected. The compressor 421 is used to provide a second heat dissipation medium, and the first heat exchanger 422 is used to allow the second heat dissipation medium to flow and exchange heat with the second heat dissipation medium to reduce the temperature of the second heat dissipation medium. When the second heat dissipation medium is a refrigerant, the refrigerant output by the compressor 421 is in a high-temperature and high-pressure state. Before the refrigerant flows into the second heat dissipation flow channel 12 of the heat dissipation assembly 1, the refrigerant needs to be cooled. Therefore, the first heat exchanger 422 can be provided between the output end of the compressor 421 and the heat dissipation assembly 1. The first heat exchanger 422 can be an in-vehicle condenser. After the refrigerant is output from the compressor 421, it is condensed through the first heat exchanger 422 to reduce the refrigerant temperature.

[0096] In some examples, in order to further cool the refrigerant, a fourth heat exchanger 423 can be added between the first heat exchanger 422 and the heat dissipation component 1. The fourth heat exchanger 423 can be an external condenser. After the refrigerant is output from the compressor 421, it is condensed in turn through the first heat exchanger 422 and the fourth heat exchanger 423 to reduce the temperature of the refrigerant.

[0097] In some examples, an expansion valve 46 can also be set between the second cooling component 42 and the heat dissipation component 1. The expansion valve 46 is used to adjust the flow state of the refrigerant. After the refrigerant is output from the compressor 421, it is condensed in turn through the first heat exchanger 422 and the fourth heat exchanger 423, and then enters the heat dissipation component 1 after the flow state is adjusted by the expansion valve 46 to ensure the heat exchange efficiency of the second heat dissipation medium.

[0098] In some examples, a gas-liquid separator 47 may be further provided between the heat dissipation component 1 and the suction port of the compressor 421. After the refrigerant completes the heat exchange, a small amount of liquid droplets may still remain in the refrigerant due to the entrainment of liquid droplets. By providing the gas-liquid separator 47 between the heat dissipation component 1 and the suction port of the compressor 421, the liquid refrigerant can be stored in the gas-liquid separator 47, thereby achieving the function of gas-liquid separation to improve the flow stability of the refrigerant.

[0099] In some embodiments, the heat dissipation system 4 further includes a motor module 43, which is connected in series between the electronically controlled power module 3 and the first cooling assembly 41. That is, the motor module 43 and the electronically controlled power module 3 share a cooling circuit for a first heat dissipation medium. The first cooling assembly 41 simultaneously provides the first heat dissipation medium to the motor module 43 and the electronically controlled power module 3 to cool and dissipate heat from the motor module 43 and the electronically controlled power module 3, thereby ensuring stable operation of the motor module 43 and the electronically controlled power module 3. By having the motor module 43 and the electronically controlled power module 3 share the same cooling circuit, the integration of the heat dissipation system 4 can be effectively improved, and the utilization rate of the first heat dissipation medium can be increased.

[0100] In some embodiments, heat dissipation system 4 further includes a battery heat exchange module 44, which includes a second heat exchanger 441. Second heat exchanger 441 is connected in parallel with heat dissipation assembly 1, which is in turn connected to a second cooling assembly 42. Second cooling assembly 42 is configured to provide a second heat dissipation medium to second heat exchanger 441, enabling heat exchange between the second heat dissipation medium and the batteries in battery heat exchange module 44. Specifically, second heat exchanger 441 is connected in parallel with heat dissipation assembly 1. After condensation by first heat exchanger 422 and fourth heat exchanger 423, refrigerant output from compressor 421 enters second heat exchanger 441 and heat dissipation assembly 1, respectively. After heat exchange with the batteries and heating element 2, the refrigerant is separated from the battery by gas-liquid separator 47 before being drawn into compressor 421, thereby circulating the refrigerant within heat dissipation system 4. By integrating the heat dissipation of electronically controlled power module 3 and in-vehicle battery heat exchange module 44 within the same heat dissipation system 4, the integration of heat dissipation system 4 can be improved.

[0101] It should be noted that an expansion valve 46 can also be set between the second cooling component 42 and the second heat exchanger 441, and between the second heat exchanger 441 and the compressor 421. The expansion valve 46 is used to adjust the flow state of the refrigerant. After the refrigerant is output from the compressor 421, it is condensed in turn through the first heat exchanger 422 and the fourth heat exchanger 423, and then enters the second heat exchanger 441 after the flow state of the refrigerant is adjusted by the expansion valve 46, and heat exchanges with the battery to reduce the temperature of the battery. After the heat exchange, the refrigerant is further adjusted in flow state by the expansion valve 46 and separated into gas and liquid by the gas-liquid separator 47, and then is sucked into the compressor 421, thereby realizing the circulation of the refrigerant in the battery heat exchange module 44.

[0102] In some embodiments, heat dissipation system 4 further includes an in-vehicle cooling module 45, which includes a third heat exchanger 451. Third heat exchanger 451 is connected in parallel with heat dissipation assembly 1, which is in turn connected to second cooling assembly 42. Second cooling assembly 42 is configured to provide a second heat dissipation medium to third heat exchanger 451, enabling the second heat dissipation medium to exchange heat with the in-vehicle cooling space in in-vehicle cooling module 45. Specifically, third heat exchanger 451 is connected in parallel with heat dissipation assembly 1. After condensation by first heat exchanger 422 and fourth heat exchanger 423, refrigerant output from compressor 421 enters third heat exchanger 451 and heat dissipation assembly 1, respectively. After heat exchange with the in-vehicle cooling space and heating element 2, the refrigerant is separated from the in-vehicle cooling space by gas-liquid separator 47 before being drawn into compressor 421, thereby achieving refrigerant circulation within heat dissipation system 4. By integrating the heat dissipation of electronically controlled power module 3 and in-vehicle cooling module 45 within the same heat dissipation system 4, the integration level of heat dissipation system 4 can be improved.

[0103] It should be noted that an expansion valve 46 can also be set between the second cooling component 42 and the third heat exchanger 451. The expansion valve 46 is used to adjust the flow state of the refrigerant. After the refrigerant is output from the compressor 421, it is condensed in turn through the first heat exchanger 422 and the fourth heat exchanger 423, and then enters the third heat exchanger 451 after the flow state of the refrigerant is adjusted by the expansion valve 46, and heat exchange is performed with the refrigeration space in the vehicle to reduce the temperature of the refrigeration space in the vehicle. The refrigerant after heat exchange is then separated into gas and liquid by the gas-liquid separator 47, and then sucked into the compressor 421, thereby realizing the circulation of the refrigerant in the refrigeration module 45 in the vehicle.

[0104] In some embodiments, the third heat exchanger 451 in the in-vehicle refrigeration module 45, the second heat exchanger 441 in the battery heat exchange module 44, and the heat dissipation assembly 1 are connected in parallel to each other, so that the in-vehicle cooling, the heat dissipation of the in-vehicle battery, and the heat dissipation of the heating element 2 are all integrated in the same heat dissipation system 4, so as to further improve the integration of the heat dissipation system 4, effectively reduce the space occupied by the heat dissipation system 4, and at the same time reduce the manufacturing cost and improve the safety and reliability of the heat dissipation system 4.
