Technical Field

The utility model relates to a new motor evaporative cooling device belongs to the radiating application of motor field.

Background

At present, most of the motor cooling which is generally used in the market adopts air cooling and water cooling modes, and the air cooling mode is adopted, because the cooling medium is air, the surface area of the heating part which is contacted with the air is smaller, the heat exchange efficiency is lower, so the motor is not suitable for a high-power motor when the air cooling mode is adopted to cool the motor; the water cooling mode mostly adopts a motor shell as a water cooling runner or a metal water cooling pipe is arranged on the motor shell, because the motor shell and the water cooling pipe are made of metal materials, water is used as a cooling medium to run in the metal pipeline for a long time and is easy to corrode the metal pipe and scale in the metal pipe, the service life of a product is reduced, later maintenance is difficult, and if the water cooling mode has a leakage phenomenon, the motor is easy to burn and serious safety accidents occur because the water is not insulated;

SUMMERY OF THE UTILITY MODEL
