Description

Technical Field

[0001] The utility model belongs to the technical field of motor casings, and particularly relates to a motor casing with a heat dissipation structure. Background Art

[0002] A motor refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction; the motor casing is an indispensable accessory on the outside of the motor. The internal structure of existing motors is mostly to install various accessories such as the stator and rotor together inside a cylindrical inner cover to complete the unified assembly of the accessories, and then the inner cover together with various accessories are installed inside the casing to play a protective and sealing role. When the motor is working, the various parts inside it will generate heat. In order to dissipate heat, the surface of the motor casing is generally provided with cooling fins to increase the heat dissipation area of ​​the casing so that the heat inside the motor can be dissipated from the casing and the cooling fins.

[0003] However, the heat dissipation effect under this method is not good. The reason is that in order to ensure smooth assembly, there is often a certain gap between the inner wall of the shell and the inner cover of the motor. The two are not tightly fitted, which leads to poor heat transfer effect. Heat cannot be efficiently transferred to the cooling fins, thereby affecting the heat dissipation effect. Therefore, it is necessary to design a new motor shell to solve this problem. Utility Model Content
