Abstract

The invention relates to a mining new energy automobile explosion-proof motor cooling water jacket. The inner side of the cooling water jacket is a smooth hole and is matched with a motor stator. Water channels are arranged on the outer side of the cooling water jacket and evenly distributed along the circumference, and the cooling water jacket is pressed into the motor shell through an assemblyprocess. The cooling water jacket is good in sealing performance, good in cooling effect and particularly suitable for being used by mining new energy vehicles.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of explosion-proof motors, in particular to a cooling water jacket for mining new energy automobile explosion-proof motors with compact structure, good waterproof and dustproof effect, and high reliability. [0003] (2) Background technology [0004] Due to the explosion-proof requirements of explosion-proof new energy vehicle motors, the motor housing is usually designed to be thicker, resulting in a larger weight of the motor and poor heat dissipation performance, which affects the output torque of the motor. [0005] (3) Contents of the invention [0006] The object of the present invention is to provide a cooling water jacket for explosion-proof motors of mining new energy vehicles with good heat dissipation effect and high reliability. [0007] To achieve the above object, the present invention takes the following technical solutions: [0008] Including the cooling water jacket of the explos...
