In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] The heat dissipation device, the controller 100 and the vehicle according to the embodiments of the present invention are described below with reference to the accompanying drawings.

[0056] like Figure 1 , Figure 2 As shown, the heat dissipation device according to the embodiment of the present invention includes: a heat dissipation plate 10 and a heat conduction and heat dissipation component 30 .

[0057] The heat conduction and heat dissipation assembly 30 is disposed on the heat dissipation plate 10 and includes fins 32, which are used to guide the airflow direction and dissipate the heat of the heat dissipation plate 10. The fins 32 are rotatably disposed on the heat dissipation plate 10, and the heat dissipation plate 10 is suitable for connecting the heat dissipation element.

[0058] It can be understood that the heat sink 10 is connected to the heat sink to be cooled, that is, the heat of the heat sink is transferred to the heat sink 10, and while the heat sink 10 is dissipating heat, it can also provide heat dissipation for the heat sink.

[0059] As a result, the airflow can simultaneously pass through the surface of the heat sink 10 and blow toward the fins 32. The airflow passing through the surface of the heat sink 10 can directly produce a heat dissipation effect on the heat sink 10. When the fins 32 are rotated to different angles, the size of the windward surface of the fins 32 relative to the airflow changes, and the flow direction of the airflow is guided by the fins 32, so that the amount of airflow flowing to the heat sink 10 and the flow direction of the airflow change, and then the heat dissipation effect directly produced by the airflow on the heat sink 10 also changes, thereby achieving the adjustment of the heat dissipation efficiency of the heat sink 10 and the heat sink.

[0060] The larger the windward surface of the fin 32 relative to the airflow is, the greater the amount of airflow flowing to the heat sink 10 is, and the higher the heat dissipation efficiency of the airflow on the heat sink 10 is.

[0061] The heat dissipation device of the present invention is provided with a heat-conducting heat dissipation component 30 , and while the airflow directly dissipates heat from the heat dissipation plate 10 , the overall heat dissipation efficiency of the heat dissipation plate 10 can be adjusted by adjusting the angle of the fins 32 .

[0062] In the present invention, there is no limitation on the structure of the heat sink 10. The heat sink 10 may be a separately provided heat conducting plate, or the heat sink 10 may directly constitute a part of the housing of the heat sink. Figure 1-Figure 3 In the example, the heat sink 10 constitutes a part of the housing of the controller 100 , that is, the heat sink 10 is the upper top plate of the controller 100 .

[0063] In some embodiments, Figure 1 , Figure 2 As shown, the heat-conducting heat-dissipating assembly 30 further includes a supporting assembly 31 , which is disposed on the heat-dissipating plate 10 , and the fins 32 are rotatably disposed on the heat-dissipating plate 10 through the supporting assembly 31 .

[0064] It can be understood that the support assembly 31 is on the heat sink 10 , so that the heat of the heat sink 10 is transferred to the support assembly 31 , and then transferred to the fins 32 through the support assembly 31 .

[0065] Thus, the heat of the heat sink 10 can be conducted to the fins 32, and the airflow blows toward the fins 32 to dissipate the heat of the fins 32. Thus, the heat conduction and heat dissipation path of the heat sink 10 are increased, and the heat can be dissipated in the heat sink 10 and the fins 32 at the same time, thereby improving the overall heat dissipation efficiency of the heat sink 10.

[0066] In addition, when the fins 32 are rotated to different angles, the size of the windward surface of the fins 32 relative to the airflow changes, so that the heat dissipation effect of the airflow on the fins 32 also changes, thereby adjusting the heat dissipation efficiency. Among them, the larger the windward surface of the fins 32 relative to the airflow, the higher the heat dissipation efficiency of the airflow on the fins 32.

[0067] Furthermore, the support assembly 31 includes: a fixed part 311 and a movable part. The fixed part 311 is connected to the heat sink 10, and the fin 32 is rotatably connected to the fixed part 311, and the rotation axis of the fin 32 is fixed relative to the heat sink 10. The movable part is movably arranged on the heat sink 10, and the contact point between the movable part and the fin 32 deviates from the rotation axis of the fin 32, so that the movable part can drive the contact point to move tangentially relative to the rotation axis, so that the movable part drives the fin 32 to rotate around the rotation axis when the movable part moves.

[0068] Therefore, the support assembly 31 limits the position of the fin 32 relative to the heat sink 10 through the fixing member 311, and drives the fin 32 to rotate about a fixed rotation axis through the movable member to realize the rotation of the fin 32, so that the rotation of the fin 32 can be controlled by controlling the movable member.

[0069] In the present invention, the type of movable parts is not limited. For example, the movable part can be a gear set for driving the connecting fins 32. Figure 5 , Figure 6 In the example, the movable member includes a rack 312 .

[0070] Furthermore, if Figure 5 , Figure 6 As shown, the fin 32 includes a gear 321 and a rotating shaft 322, the axes of the gear 321 and the rotating shaft 322 coincide with the rotation axis, and the rotating shaft 322 is rotatably connected to the fixed member 311. The movable member includes: a rack 312, the rack 312 is meshed with the gear 321, and the rack 312 is movably arranged on the heat dissipation plate 10 to drive the gear 321 to rotate.

[0071] Thus, the rotating shaft 322 constitutes the rotating axis of the fin 32, and the rotating shaft 322 is connected to the fixing member 311, so that the rotating axis of the rotating shaft 322 is fixed. The axes of the gear 321 and the rotating shaft 322 coincide with the rotating axis, that is, the setting position of the gear 321 is stable, so that when the rack 312 moves relative to the heat sink 10, the gear 321 can rotate under the drive of the rack 312, that is, the fin 32 can rotate.

[0072] Furthermore, the support assembly 31 further includes: a slide groove member 313 and a slide rail 314. The slide groove member 313 is provided on the heat dissipation plate 10, and the slide groove member 313 defines a slide groove. The slide rail 314 is slidably fitted in the slide groove, and the slide rail 314 is connected to the rack 312, so that the rack 312 can move synchronously with the slide rail 314.

[0073] Thus, the slide groove can limit the moving direction of the slide rail 314 and improve the stability of the moving direction of the slide rail 314, thereby improving the stability of the rack 312 moving with the slide rail 314 and improving the contact stability between the rack 312 and the gear 321.

[0074] In the present invention, there is no restriction on the extending direction of the slideway. Figure 4 In the example, the slide groove is set as a straight groove, the slide rail 314 moves along a straight line in the slide groove, and the rack 312 is correspondingly set as a straight rack 312. In another example, the slide groove is set as a curved groove, the slide rail 314 moves along a curve in the curved groove, and the rack 312 is set as a curved rack corresponding to its moving trajectory to ensure that the rack 312 can stably contact the gear 321.

[0075] Furthermore, the support assembly 31 also includes: a sealing cover 315, which is arranged on the notch of the slide slot, and the sealing cover 315 encloses the slide slot into a sealed cavity, and the slide rail 314 and the rack 312 are arranged in the sealed cavity.

[0076] Thus, the sealing cover 315 can limit the slide rail 314 in the slide groove, improving the stability of the slide rail 314 in the slide groove. At the same time, the sealing cover 315 and the slide groove enclose the slide rail 314 and the rack 312 in the sealed cavity, which can protect the slide rail 314 and the rack 312, improve the structural stability of the slide rail 314 and the rack 312, thereby ensuring that the slide rail 314 can move smoothly in the slide groove and improve the stability of the rack 312 and the gear 321.

[0077] In addition, a avoidance hole (not shown) corresponding to the gear 321 is opened on the sealing cover 315. The avoidance hole can provide a space on the sealing cover 315 for the rack 312 to contact the gear 321, so that the gear 321 can contact and cooperate with the rack 312 in the sealing cavity.

[0078] The gear 321 can be inserted into the sealed cavity through the avoidance hole as a whole, and the gear 321 meshes with the rack 312 in the sealed cavity. At this time, the gear 321 is located in the sealed cavity as a whole, and the sealing cover 315 can also protect the gear 321. Alternatively, the gear 321 partially extends into the sealed cavity through the avoidance hole, so that the gear 321 is located in the sealed cavity at the meshing position with the rack 312. At this time, the installation operation when the gear 321 cooperates with the rack 312 can be facilitated.

[0079] In some embodiments, Figure 5 , Figure 6As shown, the support assembly 31 also includes: a driving member 316, the driving member 316 is connected to the heat sink 10, and is connected to the rack 312 to drive the rack 312 to move. Therefore, the driving member 316 is used to control the movement of the rack 312, and the fin 32 is driven by the rack 312 through the gear 321 to rotate, so that the driving member 316 can control the rotation of the fin 32 through the rack 312. At the same time, the driving member 316 can also be used to control the stillness of the rack 312, that is, the driving member 316 can also keep the rack 312 in a fixed position, so that the fin 32 can be maintained at a stable angle. When the fin 32 is subjected to the force of the airflow, the angle stability of the fin 32 can be improved, thereby improving the stability of the heat dissipation effect of the heat dissipation device.

[0080] It should be noted that a connection structure or a transmission structure may be provided between the driving member 316 and the rack 312. Figure 5-Figure 7 In the example, the rack 312 is fixed to the slide rail 314 , the driving member 316 is connected to the slide rail 314 and drives the slide rail 314 to move, and the rack 312 moves with the slide rail 314 .

[0081] In the present invention, there is no limitation on the type of the driving member 316. For example, the driving member 316 may be a motor or a hydraulic push rod.

[0082] In some embodiments, when there are multiple fins 32, the multiple fins 32 are arranged in at least one row, and the multiple fins 32 in each row are arranged at intervals, and one end of the multiple fins 32 in each row shares a set of support components 31, and the other end of the multiple fins 32 in each row shares another set of support components 31. When the fins 32 are arranged in multiple rows, two adjacent rows are arranged at intervals along the rotation axis of the fins 32.

[0083] It is understandable that the fins 32 in different rows are disposed at different positions of the heat sink 10 , and the heat of the heat sink 10 at different positions is likely to be different.

[0084] Thus, the fins 32 in the same row can rotate synchronously under the drive of the support assembly 31, ensuring the consistency of the heat dissipation effect of the fins 32 in the same row. The fins 32 in different rows rotate independently, so that the heat dissipation efficiency of the fins 32 in different rows can be adjusted independently, so that multiple rows of fins 32 can be set corresponding to different positions of the heat sink 10, so that the fins 32 in different rows can independently adjust the rotation angle according to the temperature of different positions of the heat sink 10, so that the heat sink can have different heat dissipation efficiencies at different positions of the heat sink 10.

[0085] In some embodiments, the heat dissipation device further includes: an air supply component 20 , the air supply component 20 is connected to the heat dissipation plate 10 , and an air supply port 21 of the air supply component 20 is arranged toward the fin 32 .

[0086] It can be understood that the air supply port 21 faces the fin 32, so that the air flow output by the air supply component 20 can blow toward the fin 32. At the same time, since the air supply component 20 is connected to the heat sink 10, the distance between the air supply port 21 and the heat sink 10 is relatively small. Therefore, under the effect of air flow diffusion, the air flow output by the air supply component 20 at least partially passes through the surface of the heat sink 10.

[0087] Thus, the airflow outputted from the air supply assembly 20 at the air supply port 21 can simultaneously pass through the surface of the heat sink 10 and blow toward the fins 32. Under the guidance of the fins 32, the airflow can flow more toward the heat sink 10 to improve the heat dissipation efficiency.

[0088] In addition, when the fins 32 are connected to the heat sink 10 through the support assembly 31, the heat of the heat sink 10 can be conducted to the fins 32, and the airflow blows toward the fins 32 to dissipate the heat of the fins 32. Thus, the heat conduction and heat dissipation path of the heat sink 10 are increased, and the heat can be dissipated in the heat sink 10 and the fins 32 at the same time, thereby improving the overall heat dissipation efficiency of the heat sink 10.

[0089] Furthermore, the air supply assembly 20 includes: a fan cover 22 and a driving fan 23. The fan cover 22 is connected to the heat sink 10, the air supply port 21 is arranged on the side of the fan cover 22 facing the fins 32, and the driving fan 23 is arranged in the fan cover 22. Thus, the fan cover 22 can protect the driving fan 23, and at the same time, it can gather the airflow generated by the driving fan 23 together, so that the airflow can be concentrated and flow out from the air supply port 21, so that the airflow can be more concentratedly blown to the fins 32 and the heat sink 10, thereby improving the heat dissipation efficiency of the heat dissipation device.

[0090] In the present invention, the shape of the fan cover 22 is not limited. Figure 1-Figure 3 In the example, the fan cover 22 is configured as a rectangular parallelepiped.

[0091] In addition, when a plurality of driving fans 23 are provided on the heat sink 10, the plurality of driving fans 23 are provided in one fan cover 22. Alternatively, a plurality of fan covers 22 may be provided, and the plurality of driving fans 23 are provided in the plurality of fan covers 22 in a one-to-one correspondence.

[0092] Furthermore, the air supply assembly 20 further includes: a grille structure 24 provided on the fan cover 22 and located at the air supply port 21. Thus, the grille structure 24 can provide protection at the air supply port 21, reduce or prevent solid impurities (such as stones) from entering the fan cover 22 from the air supply port 21, thereby improving the protection effect of the driving fan 23 and improving the working stability of the driving fan 23.

[0093] In addition, the grille structure 24 has a rectifying effect, improving the flow direction consistency of the air flow when it leaves the blower housing 22 from the air outlet 21, reducing or avoiding the eddy current generated due to different air flow directions, thereby increasing the air flow velocity and reducing the air flow noise.

[0094] In some embodiments, the heat dissipation device further includes: a flow guiding assembly 40, which is arranged on the heat dissipation plate 10 and located on the air supply side of the air supply assembly 20. The flow guiding assembly 40 has a guiding surface, and the extending direction of the guiding surface is consistent with the air outlet direction of the air outlet 21.

[0095] Thus, the flow guiding assembly 40 can play a role in guiding the air flow direction. The air flow blown out from the air outlet 21 can pass through the flow guiding assembly 40, making the air flow direction more consistent, reducing or avoiding the eddy current generated due to different air flow directions, thereby increasing the air flow velocity and reducing the air flow noise.

[0096] Among them, the extending direction of the guiding surface is consistent with the air outlet direction of the air outlet 21, which can reduce the resistance suffered by the air flow when passing through the flow guiding assembly 40, improve the efficiency of the air flow, that is, ensure the heat dissipation efficiency of the heat dissipation device.

[0097] It should be noted that when the heat dissipation device is provided with multiple rows of fins 32, the number of the flow guiding assemblies 40 can be correspondingly set to multiple, and their positions are set corresponding to the positions of the multiple rows of fins 32 and the air flow direction. For example, in Figure 1-Figure 3 In the example, the heat dissipation device is provided with four rows of fins 32, and the four rows of fins 32 are arranged in a "field" shape on the heat dissipation plate 10, and the rotation axes of all the fins 32 are parallel. In addition, in this example, a flow guiding assembly 40 is also arranged on the heat dissipation plate 10, and a flow guiding assembly 40 is arranged at each end of each row of fins 32 in the air outlet direction of the air outlet 21, so that the flow guiding assembly 40 rectifies the air flow, improving the air flow direction consistency when the air flow flows to and leaves each row of fins 32.

[0098] Furthermore, the flow guiding assembly 40 includes a plurality of flow guiding columns 41, the guiding surface is arranged on the flow guiding columns 41, and the plurality of flow guiding columns 41 are arranged in at least one row. The plurality of flow guiding columns 41 in the same row are spaced apart along a direction perpendicular to the air outlet direction of the air outlet 21.

[0099] Thus, the air flow passes through the gaps between adjacent flow guiding columns 41 to flow through the flow guiding assembly 40, thereby realizing the rectifying effect of the flow guiding assembly 40 on the air flow. And the plurality of flow guiding columns 41 are spaced apart along a direction perpendicular to the air outlet direction of the air outlet 21, enabling the flow guiding assembly 40 to rectify the air flow at multiple places in the direction perpendicular to the air outlet direction of the air outlet 21 simultaneously, improving the rectifying effect of the flow guiding assembly 40 on the air flow.

[0100] Furthermore, as Figure 1-Figure 3As shown, the guide columns 41 are arranged in at least two rows along the air outlet direction of the air outlet 21 , and fins 32 are arranged between two adjacent rows.

[0101] It can be understood that after the airflow flows out of the fan cover 22 from the air supply port 21, it flows to the guide column 41, and flows to the fin 32 after being rectified by the guide column 41. The airflow after flowing through the fin 32 can flow through the guide column 41 again to rectify the airflow once again, thereby improving the flow consistency of the airflow after passing through the fin 32, reducing or avoiding vortices generated by different airflow directions, thereby increasing the airflow velocity and reducing the airflow noise, and reducing the resistance of the airflow leaving the fin 32, that is, improving the efficiency of the air flowing through the fin 32, and improving the heat dissipation efficiency of the heat dissipation device.

[0102] In some embodiments, the rotation axis of the fin 32 is perpendicular to the air outlet direction of the air outlet 21, so as to increase the windward surface of the fin 32, improve the guiding effect of the fin 32 on the air flow direction and the heat dissipation effect of the fin 32 itself.

[0103] In addition, when there are multiple fins 32, the multiple fins 32 are arranged in at least one row, and the multiple fins 32 in each row are arranged at intervals along the air outlet direction of the air supply port 21, so that the multiple fins 32 can guide the airflow at different positions in the air outlet direction and be affected by the heat dissipation of the airflow, thereby improving the utilization rate of the airflow, improving the guiding effect of the airflow direction and the heat dissipation effect of the fins 32 themselves.

[0104] In some embodiments, the fin 32 is a long plate extending along the rotation axis of the fin 32. Thus, the fin 32 can contact the airflow at different positions along the rotation axis, thereby increasing the contact area between the fin 32 and the airflow, increasing the area for heat exchange between the airflow and the fin 32, and improving the heat dissipation effect of the airflow on the fin 32.

[0105] Furthermore, the fin 32 includes: a middle section 323 and two thinning sections 324. The middle section 323 is rotatably connected to the heat sink 10 at both ends in the length direction, and the two thinning sections 324 are connected to both sides of the middle section 323 in the width direction, and the thickness of each thinning section 324 gradually decreases in the direction away from the middle section 323.

[0106] Therefore, by setting thinning sections 324 on both sides of the middle section 323 in the width direction, the resistance encountered by the airflow when passing through the fins 32 can be reduced, and the heat exchange efficiency between the airflow and the fins 32 is affected by the airflow velocity, thereby improving the heat dissipation effect of the airflow on the fins 32.

[0107] At the same time, it is also possible to reduce the force of the airflow on the fins 32, improve the stability of the rotation of the fins 32, and improve the stability of the fins 32 when they are maintained at a fixed angle.

[0108] In addition, the middle section 323 is rotatably connected to the heat sink 10 at both ends in the length direction, so that the rotation axis of the fin 32 is located in the middle section 323, and the thickness of the thinning section 324 gradually decreases in the direction away from the middle section 323 so that the weight of the fin 32 can be concentrated on the middle section 323, thereby improving the rotation stability of the fin 32.

[0109] Furthermore, the fin 32 is provided with ventilation holes 325, which are arranged from one thinning section 324 to another thinning section 324. There is at least one ventilation hole 325, and when there are multiple ventilation holes 325, at least two ventilation holes 325 are arranged at intervals along the rotation axis of the fin 32.

[0110] Therefore, when the airflow flows to the fin 32, in addition to flowing through the surface of the fin 32, the airflow can also flow into the ventilation hole 325, thereby increasing the contact area between the airflow and the fin 32 and increasing the heat dissipation efficiency of the airflow on the fin 32. When the fin 32 rotates to different angles, the windward side of the fin 32 on the surface is different, and the airflow flow rate entering the ventilation hole 325 is also different, thereby achieving the adjustment of the heat dissipation efficiency of the fin 32 by the airflow.

[0111] In addition, by providing the ventilation holes 325 , the resistance of the fins 32 to the airflow can be reduced, thereby increasing the flow rate of the airflow when passing through the fins 32 and improving the heat dissipation efficiency of the airflow to the fins 32 .

[0112] Further, when the fin 32 is provided with a plurality of ventilation holes 325 arranged at intervals along the rotation axis, the plurality of ventilation holes 325 are interconnected within the fin 32 along the extension direction of the rotation axis.

[0113] As a result, the airflow in the ventilation hole 325 can flow along the rotation axis direction in the fin 32, thereby increasing the contact area between the airflow in the ventilation hole 325 and the fin 32, thereby further increasing the contact area between the airflow and the fin 32 and improving the heat dissipation efficiency of the airflow on the fin 32.

[0114] like Figure 8 As shown, the heat dissipation control method according to an embodiment of the present invention includes:

[0115] S1: Connect the heat sink 10 to the heat dissipation element, and arrange a heat conduction heat dissipation assembly 30 on the heat sink 10. The heat conduction heat dissipation assembly 30 includes fins 32, which are rotatably arranged on the heat sink 10, and the fins 32 are arranged with a windward surface;

[0116] S2: Preset a first power, a second power, a first temperature, and a second temperature, wherein the first power is greater than the second power, and the first temperature is greater than the second temperature;

[0117] S3: Obtaining the working power and working temperature of the heat dissipation component to be cooled;

[0118] S4.1: When the operating power is less than the second power and the operating temperature is less than the second temperature, the fin 32 is rotated so that the windward surface is parallel to the heat sink 10;

[0119] S4.2: When the operating power is greater than the second power or the operating temperature is greater than the second temperature, the fin 32 is rotated so that the angle between the windward surface and the heat sink 10 is the first angle;

[0120] S4.3: When the operating power is greater than the first power or the operating temperature is greater than the first temperature, the fins 32 are rotated so that the angle between the windward surface and the heat sink 10 is a second angle, and the second angle is greater than the first angle.

[0121] The heat dissipation control method of the present invention can control the angle of the fins 32 relative to the heat sink 10 according to the working power and temperature of the heat dissipation component to be cooled, thereby adjusting the heat dissipation effect of the heat dissipation component to be cooled, so that the heat dissipation effect of the heat dissipation component to be cooled can be adapted to its working state, thereby improving the stability of the working temperature of the heat dissipation component to be cooled.

[0122] Preferably, the obtaining of the working power and the working temperature of the heat dissipation element is to obtain the working power and the working temperature of the heat dissipation element in real time.

[0123] In some embodiments, the heat sink 10 is provided with an air supply assembly 20, the air supply assembly 20 is connected to the heat sink 10, the air supply port 21 of the air supply assembly 20 is arranged toward the fin 32, and the air flow output by the air supply assembly 20 has a first wind speed and a second wind speed, and the first wind speed is greater than the second wind speed;

[0124] S4.1: When the working power is less than the second power and the working temperature is less than the second temperature, the air supply component 20 stops working;

[0125] S4.2: When the operating power is greater than the second power or the operating temperature is greater than the second temperature, the air supply component 20 outputs an air flow at a second wind speed;

[0126] S4.3: When the working power is greater than the first power or the working temperature is greater than the first temperature, the air supply component 20 outputs an air flow of the first wind speed.

[0127] Therefore, by adjusting the output air flow speed of the air supply assembly 20, the heat dissipation effect on the heat sink 10 can be adjusted, and the heat dissipation effect on the heat dissipation element can be adapted to its working state, further improving the stability of the working temperature of the heat dissipation element.

[0128] like Figure 1 , Figure 2 As shown, the controller 100 according to the embodiment of the present invention includes the heat dissipation device of the above embodiment.

[0129] The controller 100 of the present invention adopts the heat dissipation device of the above embodiment, the heat sink 10 is connected to the controller 100, and when the fins 32 are rotated to different angles, the size of the windward surface of the fins 32 relative to the airflow changes, so that the heat dissipation effect of the airflow on the fins 32 also changes. At the same time, the flow direction of the airflow is guided by the fins 32, so that the airflow amount and the flow direction of the airflow to the heat sink 10 change, and then the heat dissipation effect directly produced by the airflow on the heat sink 10 also changes. Therefore, by setting the heat-conducting heat dissipation component 30, the overall heat dissipation efficiency of the heat sink 10 can be improved, that is, the heat dissipation efficiency of the controller 100 can be improved. At the same time, by adjusting the angle of the fins 32, the overall heat dissipation efficiency of the heat sink 10 can be adjusted, that is, the heat dissipation efficiency of the controller 100 can be adjusted.

[0130] It should be noted that the present invention does not limit the types of components disposed in the controller 100. For example, a PCB or a power component is disposed in the housing.

[0131] The vehicle according to the embodiment of the present invention includes the controller 100 of the above embodiment.

[0132] The vehicle of the present invention adopts the controller 100 of the above embodiment, and the heat sink 10 of the heat dissipation device is connected to the controller 100. When the fins 32 are rotated to different angles, the size of the windward surface of the fins 32 relative to the airflow changes, so that the heat dissipation effect of the airflow on the fins 32 also changes. At the same time, the flow direction of the airflow is guided by the fins 32, so that the airflow amount and the flow direction of the airflow to the heat sink 10 change, and then the heat dissipation effect directly produced by the airflow on the heat sink 10 also changes. Therefore, by providing the heat-conducting heat dissipation component 30, the overall heat dissipation efficiency of the heat sink 10 can be improved, that is, the heat dissipation efficiency of the controller 100 can be improved. At the same time, by adjusting the angle of the fins 32, the overall heat dissipation efficiency of the heat sink 10 can be adjusted, that is, the heat dissipation efficiency of the controller 100 can be adjusted.
