[0003] At present, the commonly used heat dissipation method for controllers is to set heat dissipation ribs on the outer surface of the controller shell and stack the heat dissipation fan on the heat dissipation ribs to assist the heat dissipation ribs in dissipating the heat generation structure inside the controller. However, this heat dissipation structure has poor heat dissipation effect and is relatively large in overall size. Utility Model Content

[0005] The present application provides a controller, which includes a shell, a control board and multiple cooling fans. The control board is arranged inside the shell. The outer surface of the shell is provided with a heat dissipation portion protruding outward. The heat dissipation portion includes multiple heat dissipation fins and multiple recessed portions arranged at intervals.

The multiple recessed portions are arranged at intervals and are all recessed in the multiple heat dissipation fins.

[0006] The controller as above further comprises a wind shield, which is arranged on the surface of the heat dissipation part away from the control board. In the plane where the control board is located, the projection of the wind shield can completely cover the projection of the heat dissipation part.

[0023] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0024] like Figures 1 to 4 As shown, an embodiment of the present application provides a controller, which includes a shell 10, a control board 20 and a plurality of cooling fans 30. The control board 20 is arranged inside the shell 10. The outer surface of the shell 10 is provided with a heat dissipation portion 11 protruding outward. The heat dissipation portion 11 includes a plurality of heat dissipation fins 111 and a plurality of recessed portions 112 arranged at intervals. The plurality of heat dissipation fans 30 are correspondingly arranged in the plurality of recessed portions 112. The plurality of recessed portions 112 are arranged at intervals and are all recessed in the plurality of heat dissipation fins 111.

[0025] In specific implementation, the controller of the embodiment of the present application includes a shell 10, a control board 20 and a plurality of cooling fans 30. The control board 20 is disposed inside the shell 10, and the plurality of cooling fans 30 are disposed in a recessed portion 112 recessed in a plurality of heat sinks 111, which can reduce the space occupied by the cooling fans 30, thereby reducing the overall volume of the controller.

[0026] During the operation of the controller, the heat emitted by the control board 20 can be transferred to the shell 10 and reach the outer surface of the shell 10, which is provided with a heat dissipation portion 11 protruding outward. The multiple heat dissipation portions 11 protruding outward can increase the surface area of ​​the shell 10, which is beneficial to heat dissipation. In addition, the heat dissipation fan 30 is arranged in the recessed portion 112, which is closer to the heat sink 111, which can further accelerate the air flow in the multiple recessed portions 112, thereby improving the heat dissipation effect.

[0027] Moreover, the evenly spaced arrangement of the multiple recesses 112 can prevent the airflows of the heat dissipation fans 30 in the recesses 112 from interfering with each other or forming eddies during operation, thereby ensuring the heat dissipation effect of the heat dissipation fans 30 .

[0028] Specifically, the cooling fan 30 is arranged parallel to the surface of the shell 10, which can increase the contact area of ​​the cooling fan 30 with the external cold air, so that more cold air can be sucked into the heat dissipation part 11 for heat exchange; multiple sheet-like heat sinks 111 are arranged in parallel and extend in a direction away from the surface of the shell 10, so that there is sufficient heat dissipation space between adjacent heat sinks 111, thereby improving the overall heat dissipation effect of the controller.

[0029] Specifically, Figure 1 As shown, the heat dissipation portion 11 includes two recessed portions 112 , and two heat dissipation fans 30 are correspondingly disposed in the two recessed portions 112 .

[0030] like Figure 1 and Figure 2 As shown, the controller of an embodiment of the present application further includes a wind shield 40, which covers the surface of the heat dissipation part 11 away from the control board 20. In the plane where the control board 20 is located, the projection of the wind shield 40 completely covers the projection of the heat dissipation part 11.

[0031] During specific implementation, when the cooling fan 30 rotates to cool the heat dissipation part 11 of the shell 10, most of the air blown out by the cooling fan 30 flows in a direction perpendicular to the surface of the shell 10. By setting the wind shield 40, it is possible to produce a blocking effect on the vertically flowing cold air, and guide the air to between multiple heat sinks 111. Moreover, in the plane where the control board 20 is located, the projection of the wind shield 40 completely covers the projection of the heat dissipation part 11, so that cold air can flow at each heat sink 111 of the shell 10, thereby improving the overall heat dissipation effect of the controller.

[0032] like Figure 1 and Figure 2 As shown, in the controller of the embodiment of the present application, the wind shield plate 40 includes a plurality of heat dissipation holes 41 arranged through the wind shield plate 40, and the plurality of heat dissipation holes 41 are arranged in positions opposite to the plurality of recessed portions 112.

[0033] In a specific implementation, a plurality of heat dissipation holes 41 and a plurality of recessed portions 112 are arranged relative to each other. When the heat dissipation fan 30 in the recessed portion 112 is in operation, the cold and hot air can be exchanged through the corresponding heat dissipation holes 41, external cold air can be absorbed, and the hot air between each heat sink 111 can be discharged through the heat dissipation holes 41, so as to improve the overall heat dissipation effect of the controller.

[0034] like Figure 1 and Figure 2 As shown, in the controller of the embodiment of the present application, a plurality of blocking portions 42 arranged in an interlaced manner are arranged in the heat dissipation hole 41 , and a plurality of flow spaces 43 are provided between the plurality of blocking portions 42 .

[0035] In a specific implementation, the multiple blocking portions 42 staggered in the heat dissipation holes 41 can protect the heat dissipation fan 30 when the heat dissipation fan 30 performs air exchange, so as to prevent the heat dissipation fan 30 from sucking in external debris and causing damage to the heat dissipation fan 30, thereby improving the service life of the heat dissipation fan 30. At the same time, the setting of the blocking portions 42 can prevent the operator from accidentally touching the heat dissipation fan 30; the setting of the multiple flow spaces 43 between the multiple blocking portions 42 ensures that when the heat dissipation fan 30 rotates, sufficient air can pass through the heat dissipation holes 41, thereby ensuring the heat dissipation effect for the controller.

[0036] like Figure 3 As shown, in the controller of the embodiment of the present application, a spoiler 113 is arranged between adjacent heat dissipation fans 30 , and the height of the spoiler 113 is greater than or equal to the height of the heat dissipation fin 111 in the direction away from the control board 20 .

[0037] In specific implementation, the spoiler 113 disposed between adjacent cooling fans 30 can completely separate the two adjacent cooling fans 30, further avoiding the phenomenon of airflow interference between the two adjacent cooling fans 30; and the height of the spoiler 113 is greater than or equal to the height of the heat sink 111, thereby enhancing the blocking effect of the spoiler 113 on the airflow on both sides, and ultimately ensuring the overall heat dissipation effect of the controller.

[0038] like Figure 3 As shown, in the controller of the embodiment of the present application, at least part of the heat sink 111 has a connecting hole 114 extending therethrough.

[0039] In a specific implementation, the setting of the connecting holes 114 can connect the gaps between the heat sinks 111 , thereby achieving heat exchange between the gaps and preventing hot air from being completely retained in the gaps between adjacent heat sinks 111 , thereby improving the heat dissipation effect of the housing 10 .

[0040] like Figure 3 As shown, in the controller of an embodiment of the present application, a plurality of baffles 113 divide the heat dissipation portion 11 into a plurality of heat dissipation zones. In one heat dissipation zone, a flow guide path is formed between the recessed portion 112 and the plurality of connecting holes 114. Along the arrangement direction of the heat dissipation fins 111, the flow guide path extends from one end of the heat dissipation zone to the other end.

[0041] During specific implementation, in a heat dissipation zone, the cold air absorbed by the heat dissipation fan 30 can flow in the guide path between the recessed portion 112 and the plurality of connecting holes 114, so that the cold air flows into the gaps between the heat dissipation fins 111, so that the cold air can cover the entire heat dissipation zone and ensure the heat dissipation effect.

[0042] like Figures 1 to 4 As shown, a controller of an embodiment of the present application, wherein the shell 10 includes an upper shell 12 and a lower shell 13, the control board 20 is detachably connected between the upper shell 12 and the lower shell 13, the heat dissipation portion 11 is arranged on the surface of the upper shell 12 facing away from the control board 20, and the surface of the upper shell 12 facing the control board 20 has a plurality of protruding heat-conducting portions 121, and the plurality of heat-conducting portions 121 are all in contact with the control board 20 through a heat-conducting adhesive.

[0043] In a specific implementation, the heat emitted by the control board 20 is transferred to the heat conducting part 121 under the heat conducting effect of the heat conducting adhesive, reaches the upper shell 12 through the heat conducting part 121, and enters the heat dissipation part 11 for further heat dissipation. Therefore, the setting of the heat conducting adhesive and the heat conducting part 121 can accelerate the transfer of heat, which has a better heat dissipation effect than the heat transferred to the upper shell 12 through the air.

[0044] Specifically, the wind shield 40 and the housing 10, the cooling fan 30 and the housing 10, and the upper housing 12, the control board 20 and the lower housing 13 are all detachably connected by connecting bolts, which facilitates the assembly and disassembly of the various parts of the controller.

[0045] In the controller of the embodiment of the present application, the heat dissipation fan 30 is electrically connected to the control board 20 via a connecting wire.

[0046] During specific implementation, the opening and closing of the cooling fan 30 can be directly controlled through the power supply and control effect of the control board 20 itself, thereby avoiding the operation of the cooling fan 30 with an external power supply, achieving the plug-and-play effect of the cooling fan 30, improving the use efficiency of the controller, and expanding the use scope of the controller.

[0047] An embodiment of the present application also provides a vehicle, which includes the above-mentioned controller.

[0048] In a specific implementation, the vehicle of the embodiment of the present application includes a controller, which includes a shell 10, a control board 20 and a plurality of cooling fans 30. The control board 20 is arranged inside the shell 10, and the plurality of cooling fans 30 are arranged in a recessed portion 112 recessed in a plurality of heat sinks 111, which can reduce the space occupied by the cooling fans 30, thereby reducing the overall volume of the controller. Moreover, the cooling fans 30 are arranged in the recessed portion 112, closer to the heat sink 111, which can further accelerate the air flow in the plurality of recessed portions 112, thereby improving the heat dissipation effect.
