The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0031] In the related art, an inductor assembly is one of the core components of an electric drive assembly for a new energy vehicle. Copper loss, hysteresis loss, and eddy current loss will occur during the operation of the inductor assembly, resulting in too high a temperature rise, affecting its service performance and lifespan. The traditional cooling solution CN221040773U generally sets a heat conduction pad on the inductor assembly, and heat exchange with the outside is carried out through the heat conduction pad to achieve cooling of the inductor assembly. However, the inductor assembly can only exchange heat with the outside through one side of the heat conduction gasket, and the heat dissipation effect is poor, seriously affecting the service performance and lifespan of the inductor assembly.

[0032] Reference is made below Figures 1 - 3 to describe a heat dissipation device for an inductor assembly according to an embodiment of the present invention.

[0033] The heat dissipation device 100 for the inductor assembly 200 according to the present invention includes: a housing and a heat conduction layer 21. An accommodation cavity for accommodating the inductor assembly 200 is formed in the housing. The housing is provided with a first wall and a second wall that are oppositely arranged. A cooling wall 11 is formed between the first wall and the second wall of the housing. A heat exchange flow channel 111 is provided on the cooling wall 11. An inlet water channel 12 and an outlet water channel 13 that are communicated with the heat exchange flow channel 111 are respectively provided on the first wall and the second wall; the heat conduction layer 21 is disposed on at least a part of the outer periphery of the inductor assembly 200, and the heat conduction layer 21 is adapted to exchange heat with the first wall, the second wall, and the cooling wall 11.

[0034] In some specific embodiments, the heat dissipation device 100 is composed of a housing and a heat conducting layer 21. The inductor assembly 200 is mainly composed of components such as windings, magnetic cores, skeletons, and copper bars. An accommodation cavity is formed inside the housing. The inductor assembly 200 is received in the accommodation cavity. The housing forms a first wall and a second wall that are disposed opposite to each other in the length direction. A cooling wall 11 is further provided at the bottom of the housing, and the cooling wall 11 is located between the first wall and the second wall. An inlet water passage 12 is formed on the first wall, an outlet water passage 13 is formed on the second wall, and a heat exchange flow passage 111 is formed on the cooling wall 11. The heat exchange flow passage 111 is respectively communicated with the inlet water passage 12 and the outlet water passage 13. The cooling medium circulates among the inlet water passage 12, the heat exchange flow passage 111, and the outlet water passage 13. The inductor assembly 200 is respectively attached to the first wall, the second wall, and the cooling wall 11, so that heat exchange is directly performed between three sides of the inductor assembly 200 and the cooling medium. Since a heat conducting layer 21 is provided on the outer periphery of the windings and magnetic cores of the inductor assembly 200, the heat conducting layer 21 can be configured as a potting glue layer. Therefore, after the inductor assembly 200 is energized and operates, the heat generated by the windings and magnetic cores can be transferred through the potting glue to multiple surfaces of the potting glue layer. Among them, since the first wall, the second wall, and the cooling wall 11 of the housing are provided with water passages and heat exchange flow passages 111 for the circulation of the cooling medium, the heat generated by the inductor assembly 200 can be consumed through the flow of the cooling medium. Although the other three surfaces of the inductor assembly 200 are not directly in contact with the cooling medium, under the action of the heat conducting medium potting glue, the heat is also transferred to the surface of the housing. The heat on the surface of the housing can be consumed through heat exchange with the outside, thereby realizing heat dissipation for multiple surfaces of the inductor assembly 200, improving the heat dissipation effect of the inductor assembly 200, and ensuring the stability and reliability of the inductor assembly 200 during operation.

[0035] In addition, an inlet nozzle and an outlet nozzle are respectively provided on the inlet water passage 12 and the outlet water passage 13. The inlet nozzle and the outlet nozzle are separately processed and then press-fitted with the housing in an interference cold connection to form an integral body. On the one hand, it can ensure that the inlet nozzle and the outlet nozzle can be processed into complex shapes adapted to the vehicle water pipe joints. On the other hand, the material properties of the separately processed inlet nozzle and outlet nozzle are stronger than those of the housing, and it can be ensured that the inlet nozzle and the outlet nozzle will not be damaged under the condition of repeatedly disassembling and assembling the water pipe joints.

[0036] According to the heat dissipation device 100 of the utility model, a first wall and a second wall are formed in the longitudinal direction of the shell, and a cooling wall 11 is also provided at the bottom of the shell, and the cooling wall 11 is located between the first wall and the second wall. A water inlet waterway 12 is formed on the first wall, and a water outlet waterway 13 is formed on the second wall. A heat exchange flow channel 111 is formed on the cooling wall 11, and the heat exchange flow channel 111 is respectively connected to the water inlet waterway 12 and the water outlet waterway 13. The cooling medium flows among the water inlet waterway 12, the heat exchange flow channel 111 and the water outlet waterway 13. The inductor assembly 200 is respectively connected to the heat exchange flow channel 111 and the heat exchange flow channel 111. The first wall, the second wall and the cooling wall 11 are in contact with each other, thereby achieving direct heat exchange between the three sides of the inductor assembly 200 and the cooling medium. Since a thermal conductive layer 21 is provided on the periphery of the windings and the magnetic core of the inductor assembly 200, the thermal conductive layer 21 can be constructed as a potting glue layer. Therefore, after the inductor assembly 200 is powered on, the heat generated by the windings and the magnetic core can be transferred to multiple surfaces of the potting glue layer through the potting glue, thereby achieving heat dissipation of multiple surfaces of the inductor assembly 200, improving the heat dissipation effect of the inductor assembly 200, and ensuring the stability and reliability of the inductor assembly 200 during operation.

[0037] According to some embodiments of the utility model, the cooling wall 11 is formed with a first edge and a second edge arranged opposite to each other, and the first edge and the second edge are respectively formed with a first diverter column 31 and a second diverter column 32 extending toward each other and arranged at intervals. The first diverter column 31, the second diverter column 32 and the edge of the cooling wall 11 jointly define a heat exchange channel 111. When the cooling medium (such as water or other coolant) flows through the first diverter column 31 and the second diverter column 32, a turbulent effect will be generated. The turbulence can break the boundary layer of the fluid and increase the contact area between the fluid and the cooling wall 11, thereby improving the heat exchange efficiency between the cooling wall 11 and the cooling medium. At the same time, the first diverter column 31 and the second diverter column 32 can ensure that the cooling medium is evenly distributed in the entire heat exchange channel 111, avoid local overheating of the cooling channel, and improve the uniformity of heat exchange between the cooling medium and the cooling wall 11.

[0038] According to some embodiments of the utility model, the heat dissipation device 100 is further provided with a heat conductive member, which is arranged on the side of the cooling wall 11 away from the accommodating cavity, the heat conductive member protrudes from the cooling wall 11 and at least part of the heat conductive member is accommodated in the heat exchange channel 111, the heat conductive member can exchange heat with the cooling medium in the heat exchange channel 111, the heat conductive member can increase the contact area between the cooling wall 11 and the cooling medium, improve the heat dissipation effect of the inductor assembly 200 in the shell, thereby reducing the temperature of the inductor assembly 200 during operation, and ensuring the stable and reliable operation of the inductor assembly 200.

[0039] According to some embodiments of the present invention, the heat conducting member includes: a heat conducting column 33 , which is structured in multiple numbers and arranged at intervals in the heat exchange channel 111 .

[0040] In some specific embodiments, the heat-conducting columns 33 are configured as multiple ones, which means that there are multiple independent heat conduction paths inside the heat exchange flow channel 111, greatly increasing the heat exchange area between the housing and the cooling medium, improving the heat exchange efficiency between the cooling wall 11 and the inductor assembly 200. The spaced arrangement of the heat-conducting columns 33 in the heat exchange flow channel 111 can optimize the flow path of the cooling medium, avoid local stagnation or dead corners that the fluid may encounter during the flow process, ensure that the cooling medium can evenly cover the entire heat exchange flow channel 111, and improve the uniformity of the heat exchange between the inductor assembly 200 and the cooling wall 11.

[0041] According to some embodiments of the present invention, the heat-conducting member further includes: a heat-conducting wall, which is arranged in the heat exchange flow channel 111 and is configured as a reciprocally bent arc.

[0042] In some specific embodiments, by configuring the heat-conducting wall as a reciprocally bent arc, the surface area of the heat-conducting wall is increased, the contact area between the cooling wall 11 and the cooling medium is enlarged, and the heat dissipation effect on the inductor assembly 200 inside the housing is improved. The reciprocally bent structure not only improves the heat exchange efficiency between the cooling wall 11 and the cooling medium, but also enhances the structural strength and stiffness of the cooling wall 11 itself. Moreover, the arc design of the heat-conducting wall can optimize the hydrodynamic characteristics of the fluid, reduce the fluid resistance, and at the same time ensure the uniform distribution of the fluid in the heat exchange flow channel 111, improving the uniformity of the heat exchange between the inductor assembly 200 and the cooling wall 11.

[0043] According to some embodiments of the present utility model, the second flow dividing columns 32 are configured to be two spaced apart from each other, the first flow dividing column 31 is disposed between the two second flow dividing columns 32, and the cooling medium is guided to flow along a more complex path, increasing the contact area between the cooling medium and the cooling wall 11, thereby improving the heat exchange efficiency between the heat exchange medium and the cooling wall 11. The heat conducting wall extends along the length direction of the housing and is composed of a first bending portion 331, a second bending portion 332, and a third bending portion 333. The first bending portion 331 is connected to the second bending portion 332, and the second bending portion 332 is connected to the third bending portion. The first bending portion 331 is disposed on the side close to the water inlet channel 12 and bends towards the direction close to the first edge, and one of the second flow dividing columns 32 is received in the first bending portion 331. The second bending portion 332 is connected to the end of the first bending portion 331 far from the water inlet channel 12, bends towards the direction close to the second edge, and the first flow dividing column 31 is received in the second bending portion 332. The third bending portion 333 is disposed on the side close to the water outlet channel 13 and is connected to the second bending portion 332, bends towards the direction close to the first edge, and the other second flow dividing column 32 is received in the third bending portion 333. The specific bending directions of the first bending portion 331, the second bending portion 332, and the third bending portion 333 not only increase the turbulence degree of the cooling medium but also play a role in guiding the flow of the cooling medium, ensuring uniform heat distribution and improving the uniformity of the cooling effect of the inductor assembly 200.

[0044] According to some embodiments of the present utility model, the heat dissipation device 100 is further provided with a first diversion section 43, a second diversion section 44, and a third diversion section 45. The first diversion section 43 is disposed on the side of the cooling wall 11 away from the accommodation cavity, and the first diversion section 43 is parallel and spaced from the end of the first bending portion 331 close to the water inlet channel 12; the second diversion section 44 is disposed on the side of the cooling wall 11 away from the accommodation cavity and between the two second flow dividing columns 32, and the second diversion section 44 is parallel and spaced from the second bending portion 332; the third diversion section 45 is disposed on the side of the cooling wall 11 away from the accommodation cavity, and the third diversion section 45 is parallel and spaced from the end of the third bending portion 333 close to the water outlet channel 13. The first diversion section 43, the second diversion section 44, and the third diversion section 45 can guide the cooling medium to flow along a predetermined path, ensuring that the cooling cutoff can evenly cover the entire heat exchange flow channel 111, avoiding local stagnation of the cooling medium, thereby improving the uniformity and efficiency of the heat exchange between the inductor assembly 200 and the cooling wall 11. The first diversion section 43, the second diversion section 44, and the third diversion section 45 also help to maintain a uniform pressure distribution within the entire heat exchange flow channel 111, avoiding pressure fluctuations caused by uneven flow of the cooling medium and ensuring the stable heat exchange performance of the cooling wall 11.

[0045] According to some embodiments of the present utility model, the heat dissipation device 100 further includes: a temperature detection device 41, which is disposed on the inductor assembly 200 and is used to detect the temperature inside the inductor assembly 200.

[0046] In some specific embodiments, the temperature detection device 41 can be disposed at the position with the highest winding temperature of the inductor assembly 200. The wire harness of the temperature detection device 41 is connected to the connector 42. A cylinder-piercing member 23 is provided on the housing. The cylinder-piercing member 23 is a component for passing through the housing and leading out internal signals to the outside. The connector 42 is connected to the cylinder-piercing member 23. At this time, the low-voltage temperature signal of the temperature detection device 41 can be led out to the outside of the housing through the cylinder-piercing member 23, thereby realizing the real-time monitoring of the highest temperature of the winding of the inductor assembly 200 inside the housing.

[0047] According to some embodiments of the present utility model, the heat dissipation device 100 further includes: a baffle 22, which is disposed in the accommodation cavity, and the baffle 22 separates the winding of the inductor assembly 200 from the copper busbar of the inductor assembly 200.

[0048] In some specific embodiments, one end of the baffle 22 is connected to the inner wall of the accommodation cavity, and the other end of the baffle 22 extends towards the open end of the accommodation cavity. When the inductor assembly 200 is fixed into the accommodation cavity, the baffle 22 is disposed between the winding of the inductor assembly 200 and the copper busbar of the inductor assembly 200 and separates the two. During the process of injecting potting glue into the inductor assembly 200, the baffle 22 can prevent the potting glue from flowing into areas that should not be covered, such as the copper busbar. At the same time, the baffle 22 can also ensure that the potting glue can evenly wrap the winding and the magnetic core without excessive accumulation in some areas or leaving voids in other places, improving the uniformity and reliability of the potting of the winding and the magnetic core of the inductor assembly 200 and enhancing the stability of the inductor assembly 200.

[0049] In addition, the baffle 22 can also play a role in positioning and supporting the inductor assembly 200 during the potting process of the inductor assembly 200, ensuring that the winding and the magnetic core maintain the correct relative position during the curing of the potting glue and preventing the inductor assembly 200 from being affected by movement or deformation and thus affecting its potting quality.
