Description

Technical Field

[0001] The utility model relates to the technical field of motor casings, in particular to a motor heat dissipation casing. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetic-electromotive force to generate a rotating torque.

[0003] Application number CN202022794867.2 discloses a shell for heat dissipation of marine electric motors, including a shell, an inner cavity is provided in the shell, an opening is provided on the shell, a piston is abutted in the opening, a connecting block is provided inside the shell, a rotating blade is fixedly connected to the connecting block, a heat dissipation hole is provided on the shell, and outlets are provided on both side walls of the shell, and a screw is threadedly connected to the outlet. After a massive search, most motors including those in this application will have heat dissipation ports on the shell to improve the heat dissipation effect. These heat dissipation ports are arranged on the top of the shell and on the bottom of the shell. However, no matter where they are, the hot air blown out from the shell is likely to cause dust in the surrounding area, which makes the surface of the motor shell easily covered with dust, which then affects the heat dissipation of the shell. What's worse, dust enters the shell and causes direct damage to the motor. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0025] A motor heat dissipation housing provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings. Embodiment 1

[0026] Combination Figure 1-3 As shown, the utility model provides a motor heat dissipation housing, including a housing module 100 and an air guide module 200, wherein the housing module 100 includes a rear end housing 110, a front end housing 120 connected to the rear end housing 110, an end cover 130 connected to the front end housing 120, a filter screen 140 embedded in the outer end of the rear end housing 110, a support frame 150 connected to the bottom of the rear end housing 110, and a plurality of heat dissipation ports 160 opened on the front end housing 120;

[0027] The air guide module 200 includes a plurality of air guide covers 210 connected to the front end shell 120, a filter cloth 220 connected between the front end shell 120 and the air guide covers 210, and a plurality of slots 230 opened on the outside of the front end shell 120. The plurality of slots 230 are respectively coaxial with the plurality of heat dissipation ports 160, and the plurality of heat dissipation ports 160 are respectively located inside the plurality of air guide covers 210.

[0028] Furthermore, a plurality of heat dissipation openings 160 are arranged in a ring at equal intervals, and the heat dissipation openings 160 are connected to the interior of the front end shell 120 . With this layout design, the heat in the front end shell 120 and the rear end shell 110 can be discharged from any direction, thereby improving the heat dissipation effect. Embodiment 2

[0029] Combination Figure 1 and Figure 3 As shown, based on the first embodiment, two heat dissipation fins 300 are installed on the outside of the air guide cover 210, and the two heat dissipation fins 300 are vertically symmetrical about the vertical center plane of the air guide cover 210. The heat dissipation fins 300 can improve the heat dissipation effect of the rear end shell 110 and the front end shell 120.

[0030] Specifically, the air guide cover 210 is made of the same material as the heat sink fins 300 . The heat sink fins 300 are made of metal material. The use of the same material reduces the difficulty of material selection when manufacturing the air guide cover 210 . Embodiment 3

[0031] Combination Figure 1 and Figure 3 As shown, in the above embodiment, two stabilizing frames 400 are provided at the bottom of the rear end shell 110, and the two stabilizing frames 400 are respectively fixed to the outer walls of the two air guide covers 210. The stabilizing frames 400 can be provided to place the motor stably.

[0032] Specifically, the bottom of the stabilizing frame 400 is flush with the bottom of the supporting frame 150 . This structural design can prevent the front end shell 120 from tipping down.

[0033] The working principle and use process of the utility model are as follows: when the device is put into actual use, an external cooling fan is installed outside the filter 140, and then the heat dissipation effect inside the rear end shell 110 and the front end shell 120 is increased, and then the heat is discharged from multiple heat dissipation ports 160, and then under the guidance of the wind guide cover 210, the hot air passes through the filter cloth 220 and then blows to the front end of the end cover 130. The hot air blocked by the filter cloth 220 has a reduced flow rate, which effectively reduces the degree of dust and also prevents dust from entering the front end shell 120, which can not only maintain the heat dissipation effect but also reduce the probability of motor damage.

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
