Motor with improved heat dissipation effect

摘要

A heat dissipation device for handy, effective, and cost saving heat dissipation for all kinds of motors utilizing a plurality of thermal conducting pipes filled with an easily evaporative liquid and a capillary material disposed uniformly in the surroundings of windings and in the core slots. These pipes are brought to be in contact with a heat dissipation plate and can be further communicated with a circulating refrigerant.
