Water cooling method for motor

Abstract

The invention discloses a water cooling method for a motor. The water cooling method includes a step a of arranging a rubber water pipe outside a housing in such a manner that the rubber water pipe winds on a housing between two mounting bases along the axial direction to form a spiral structure, wherein one end of the rubber water pipe is a water inlet end and the other end of the rubber water pipe is a water outlet end; a step b of communicating the water inlet end and the water outlet end of the rubber water pipe with a same water tank where a water pump and a cooler for cooling the cooling water are arranged; and a step c of injecting clear water for cooling in the water tank before working of the motor, and starting the water pump and the cooler during working of the motor to allow the cooling water to circulate between the water tank and the rubber water pipe. A water pipe is wound outside the housing, and material of the water pipe, the winding means of the water pipe and the internal diameter ratio of the water pipe and housing are perfectly chosen to form an inseparable part of the method, so as to improve the heat radiation effect along the radial direction.

Description

technical field [0001] The invention belongs to the field of electric motors, in particular to a water cooling method for electric motors. Background technique [0002] The motor is a widely used power device. It is generally composed of a casing, a stator and a rotor. The outer wall of the casing is provided with a set of axial cooling grooves along the circumference, and the two ends of the bottom of the casing are respectively provided with a mounting support. . The inner wall of the shell is fixed with a stator, which rotates with the rotor, and the output shaft on the rotor passes through the through hole at one end of the shell, and the other end of the shell is equipped with a heat dissipation end cover, which is used to protect the motor cooling fan inside. When in use, the motor will generate heat. If the heat is not effectively dissipated, it will not only affect the transmission efficiency and precision, but also affect the service life of the motor. Although t...

Problems solved by technology

[0005] In the process of use, we found that although the cooling effect of the existing water-cooled motor is improved compared with the way of using the cooling fan alone, the cooling effect is still not ideal; more importantly, the existing auxiliary cooling method not only needs Adding at least 4 more self-made parts, the structure is very complicated, and often needs to change the internal structure of the motor, which greatly increases the production difficulty and manufacturing cost, and in order to take away the heat of the motor through the cooling water, these added parts A water-cooling cavity for cooling water flow is formed between the shell and the shell, which puts forward high precision requirements for the manufacturing accuracy of the shell and the waterproof sealing of the water-cooling cavity. The internal energized parts come into contact, resulting in electric shock, which can lead to serious safety accidents
