DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5, the embodiments proposed in this application are as follows: A motor housing with fast heat dissipation, including a front cover 1. Mounting posts 2 are equiangularly installed on one side of the front cover 1. One end of the mounting post 2 is installed with a rear cover 4. Installation grooves 8 are provided on the inner sides of both the front cover 1 and the rear cover 4. Both ends of the mounting post 2 are rotatably connected to the front cover 1 and the rear cover 4 respectively. A sealing plate 3 is installed on the outer side of the mounting post 2, and the sealing plate 3 is symmetrically arranged about the center of the mounting post 2. After the mounting post 2 rotates, the gap between the sealing plate 3 and the mounting post 2 can be controlled, thereby adjusting the air intake volume and regulating the heat dissipation efficiency;

[0023] A circulation hole 6 is provided on the inner side of the rear cover 4. A first connecting flow channel 9 is provided on the inner side of the front cover 1. A second connecting flow channel 12 is provided on the inner side of the rear cover 4, and the second connecting flow channel 12 is arranged in a staggered manner with the first connecting flow channel 9. The circulation hole 6 is communicated with both the second connecting flow channel 12 and the first connecting flow channel 9, so that the coolant can flow through the circulation hole 6, the first connecting flow channel 9 and the second connecting flow channel 12, thereby increasing the heat dissipation effect. While cooling the mounting post 2, when the internal and external air flows and contacts the mounting post 2, heat exchange can be realized, thereby cooling the air and improving the heat exchange efficiency.

[0024] Limit rings 10 are installed at both ends of the mounting post 2, and each limit ring 10 is in a snap-fit rotational connection with the front cover 1 and the rear cover 4 respectively, making the connection between the mounting post 2 and the front cover 1 and the rear cover 4 more stable.

[0025] A first exhaust hole 7 is provided on the inner side of the front cover 1, and the first exhaust hole 7 is arranged in a staggered manner at equal angles with the first connecting flow channel 9. A second exhaust hole 11 is provided on the inner side of the rear cover 4, and the second exhaust hole 11 is arranged in a staggered manner at equal angles with the second connecting flow channel 12, and the second exhaust hole 11 is arranged in a staggered manner with the first exhaust hole 7, so that both the front cover 1 and the rear cover 4 have corresponding exhaust structures. Even after the sealing plate 3 and the mounting post 2 are closed, corresponding air flow can still be carried out to avoid complete closure.

[0026] A dust-proof net 5 is also installed on the surface of the rear cover 4 for filtering external air impurities.
