Description

Technical Field

[0001] The utility model relates to the field of automobile radiators, in particular to a motor heat sink. Background Art

[0002] When an automobile motor runs for a long time, heat will be generated. In order to dissipate the heat of the motor, a fan blade is installed at the tail end of the motor, and a plurality of heat sinks are manufactured on the motor housing. The fan blade extracts the heat inside the motor and dissipates the heat in combination with the heat sinks. The larger the contact area between the heat sinks and the air, the more conducive to heat dissipation. However, in the prior art, the method of adding heat sinks to the housing is still limited by the installation space, resulting in a small number of heat sinks and an insufficient rated heat dissipation area, so that the heat cannot be dissipated in time.

[0003] Therefore, the traditional motor heat sink is now difficult to meet the heat dissipation requirements of the motor, so a new motor heat sink is proposed to solve the above problems. Content of the Utility Model

[0004] The utility model overcomes the deficiencies of the prior art and provides a motor heat sink.

[0005] To achieve the above object, the technical solution adopted by the utility model is: a motor heat sink, comprising: a heat sink body and a plurality of heat dissipation fins arranged on the radiator body, the heat sink body is a hemispherical structure, the hemispherical structure includes a convex surface and a concave surface, and a plurality of the heat dissipation fins are arranged on the convex surface;

[0006] The heat dissipation fins are radially and outwardly sheet-shaped protrusions along the convex surface, the heat dissipation fins include a bending portion and a heat dissipation portion, and a heat dissipation ring is arranged on the convex surface;

[0007] The bending portion is arranged above the heat dissipation portion, the bending portion is arranged on the heat dissipation ring, and the width of the heat dissipation portion is at least 3 times that of the bending portion.

[0008] In a preferred embodiment of the utility model, a plurality of fixing grooves are arranged on the concave surface, and the fixing grooves are polygonal structures.

[0009] In a preferred embodiment of the utility model, a fixing ring is arranged on the concave surface, and the fixing grooves are annularly arranged along the fixing ring.

[0010] In a preferred embodiment of the utility model, a clamping groove is arranged on the fixing ring, and the clamping groove is a trapezoidal structure.

[0011] In a preferred embodiment of the utility model, the heat dissipation portion is in a fan-shaped structure.

[0012] In a preferred embodiment of the present utility model, the bent portion is in a triangular shape, and the end of the triangle has a chamfer.

[0013] In a preferred embodiment of the present utility model, the heat dissipation fins include fixed-end heat dissipation fins, and heat dissipation rings are provided on the fixed-end heat dissipation fins.

[0014] In a preferred embodiment of the present utility model, anti-slip grooves are provided on the concave surface, and the anti-slip grooves penetrate through the heat dissipation fin body.

[0015] In a preferred embodiment of the present utility model, a plurality of the heat dissipation fins are annularly distributed on the convex surface, and the distances between the plurality of heat dissipation fins are the same.

[0016] The present utility model solves the defects existing in the background art, and the present utility model has the following beneficial effects:

[0017] (1) The heat dissipation fin body of the present utility model has a concave surface and a convex surface. The concave surface is the fixed end for installing the heat dissipation fin body on the motor, which is convenient for disassembly and maintenance. A plurality of heat dissipation fins are provided on the convex surface, and the heat dissipation fins are provided with heat dissipation portions and bent portions. Then, the heat dissipation space between the heat dissipation fins is increased, and the heat generated by the motor can be taken away more quickly.

[0018] In addition, the bent portion is arranged above the heat dissipation portion, and the width of the heat dissipation portion is at least three times that of the bent portion. Therefore, the distance between two heat dissipation fins is smaller, and the number of heat dissipation fins that can be provided on the heat dissipation fin body is larger, so that the heat dissipation area is relatively increased, thereby increasing its heat dissipation speed.

[0019] (2) The heat dissipation portion of the heat dissipation fins of the present utility model is bent inward under the action of the bent portion. Therefore, when a plurality of heat dissipation fins are arranged together, a certain distance is maintained. Since the heat dissipation portion is in a fan-shaped structure, when the heat dissipation fins dissipate heat, the air volume blown by the fan installed at the tail end of the motor can be fully blown into each heat dissipation fin, and thus the heat dissipation is more rapid.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, a motor heat sink includes: a heat sink body 1 and a plurality of heat dissipation fins 10 arranged on the radiator body. The heat sink body 1 is a hemispherical structure, which includes a convex surface 11 and a concave surface 12. A plurality of heat dissipation fins 10 are arranged on the convex surface 11. The heat dissipation fins 10 are sheet-shaped protrusions radially outward along the convex surface 11. The heat dissipation fins 10 include a bent portion 100 and a heat dissipation portion 101. A heat dissipation ring 110 is arranged on the convex surface 11. A plurality of heat dissipation fins 10 are arranged on the convex surface 11, and the heat dissipation fins 10 are provided with a heat dissipation portion 101 and a bent portion 100. Then the heat dissipation space between each heat dissipation fin 10 is increased, and the heat generated by the motor can be taken away faster. Compared with the rectangular heat dissipation fins 10 in the prior art, the heat dissipation efficiency of the heat dissipation fins 10 of the present invention is increased by more than 13%.

[0033] The bent portion 100 is arranged above the heat dissipation portion 101 and is arranged on the heat dissipation ring 110. The width of the heat dissipation portion 101 is at least three times that of the bent portion 100. Since the bent portion 100 is arranged above the heat dissipation portion 101 and the width of the heat dissipation portion 101 is at least three times that of the bent portion 100, the distance between two heat dissipation fins 10 is smaller, so that the number of heat dissipation fins 10 that can be arranged on the heat sink body 1 is larger, and the heat dissipation area is relatively increased, thereby increasing its heat dissipation speed.

[0034] In a preferred embodiment of the present invention, a plurality of fixing grooves 120 are arranged on the concave surface 12. The concave surface 12 is a fixed end for installing the heat sink body 1 on the motor, which is convenient for disassembly and maintenance. The fixing grooves 120 are polygonal structures. A fixing ring 121 is arranged on the concave surface 12, and the fixing grooves 120 are arranged in a circular arrangement along the fixing ring 121. The polygonal structure increases the contact surface between the heat sink and the motor, making its connection more stable. The circular arrangement is more suitable for the shape of the motor, which is convenient for installation and disassembly. A clamping groove 122 is arranged on the fixing ring 121, and the clamping groove 122 is a trapezoidal structure. An anti-detachment groove 123 is arranged on the concave surface 12, and the anti-detachment groove 123 penetrates the heat sink body 1. The structural design of the clamping groove 122 and the anti-detachment groove 123 strengthens the connection between the heat sink and the motor.

[0035] In a preferred embodiment of the present invention, the heat dissipation portion 101 is in a fan-shaped structure, and the bent portion 100 is in a triangular shape with a chamfer 1000 at the triangular end. The heat dissipation portion 101 of the heat dissipation fin 10 is bent inward under the action of the bent portion 100. Therefore, when a plurality of heat dissipation fins 10 are arranged together, a certain distance is maintained. Since the heat dissipation portion 101 is in a fan-shaped structure, during the heat dissipation process of the heat dissipation fin 10, the air volume blown by the fan installed at the tail end of the motor can be fully blown into each heat dissipation fin 10, and thus the heat dissipation is more rapid.

[0036] In a preferred embodiment of the present utility model, the heat dissipation fin 10 includes a fixed-end heat dissipation fin 10, and a heat dissipation ring 102 is provided on the fixed-end heat dissipation fin 10.

[0037] In a preferred embodiment of the present utility model, a plurality of heat dissipation fins 10 are annularly distributed on the convex surface 11, and the intervals between the plurality of heat dissipation fins 10 are the same, making the overall heat dissipation of the heat sink more uniform.

[0038] When the present utility model is in use, the concave surface 12 of the heat sink body 1 is aligned with the motor housing and connected thereto. During the long-term operation of the automotive motor, heat is generated. During the heat dissipation process, the air volume continuously blown by the fan installed at the tail end of the motor. At this time, a plurality of heat dissipation fins 10 provided on the convex surface 11 dissipate the heat of the motor. Since the heat dissipation fins 10 are provided with heat dissipation portions 101 and bending portions 100, the heat dissipation space between the heat dissipation fins 10 is increased, and the heat generated by the motor can be taken away faster. Compared with the heat dissipation fins 10 of the rectangular shape directly provided on the motor housing in the prior art, the heat dissipation efficiency of the heat dissipation fins 10 of the present utility model is increased by more than 13%.

[0039] At the same time, the bending portion 100 is provided above the heat dissipation portion 101, the bending portion 100 is provided on the heat dissipation ring 110, and the width of the heat dissipation portion 101 is at least three times that of the bending portion 100. Therefore, the distance between two heat dissipation fins 10 is smaller, and the number of heat dissipation fins 10 that can be provided on the heat sink body 1 is larger, so that the heat dissipation area is relatively increased, thereby increasing its heat dissipation speed. This solves the problem in the prior art that the number of heat sinks is not enough to reach the rated heat dissipation area, resulting in the inability to dissipate heat in time.

[0040] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the essential technology of the present utility model, and all belong to the protection scope of the present utility model.
