Description

Technical Field

[0001] This utility model specifically relates to the field of motor housing technology, and more specifically to a motor housing assembly. Background Technology

[0002] An electric motor (English: Electric machinery, commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is represented by the letter M in circuit diagrams (D in older standards). Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. A generator is represented by the letter G in circuit diagrams. Its main function is to convert mechanical energy into electrical energy.

[0003] Chinese utility model publication number CN 206850563 U discloses a motor housing, which includes an annular peripheral wall and an axial rib. The axial rib is disposed on the outer peripheral surface of the annular peripheral wall and extends axially along the annular peripheral wall. A cooling channel is formed inside the motor housing, at least a portion of which is located inside the axial rib. The cooling channel has a first interface end and a second interface end.

[0004] The aforementioned motor housing can dissipate heat over a larger area of ​​the axial ribs and annular peripheral wall through cooling channels, enhancing the heat exchange effect of the cooling channels. However, the heat dissipation effect will decrease when used outdoors or in hotter environments, thereby increasing the load on the motor. To address this, we provide a motor housing assembly that includes a front and rear shell on both sides of the outer casing, and adds cooling water to the inside. This allows the air inside the casing to cool down further. In conjunction with the rotation of the fan blades, the air inside the casing can be drawn out, and cooler air from the outside can enter through the heat dissipation holes, effectively reducing the temperature inside and compensating for the aforementioned problems.
