Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of poor heat dissipation and low motor efficiency in that the heat dissipation of the current motor mainly relies on conduction and radiation, and also relies on water jackets and external fans to forcibly dissipate heat, and provides a motor with better heat dissipation effect and high motor efficiency. High phase change heat dissipation motor

Abstract

The invention relates to the field of manufacturing of motors and aims at providing a phase change heat radiation motor. The phase change heat radiation motor comprises a housing, a front end cover, a rear end cover, a stator, a rotor, a rotating shaft and a fan, wherein a heat radiation fin component positioned on the rear side of the fan is arranged at the rear end of the rotating shaft; the rotating shaft is provided with a vacuum closed cavity with the rear end positioned on the rear side of the heat radiation fin component; a phase change working medium is arranged in the vacuum closed cavity. The phase change heat radiation motor has a relatively good heat radiation effect and relatively high efficiency.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a phase-change cooling motor. Background technique [0002] When the motor is working, a large amount of heat will be generated inside, causing the overall temperature of the motor to rise sharply, the energy consumption of each component of the system will increase, the efficiency will decrease, and in severe cases, the motor will be burned; therefore, the heat dissipation of the motor is very important. The invention of Chinese Patent Publication No. CN102594023A discloses a self-heating The motor includes a housing, a stator, a rotor, and a motor shaft, wherein the housing has an end cover, and the outer side of the end cover is provided with a fan blade that draws air from the inside of the housing, and the fan blade rotates with the motor shaft; and, for According to the position of the fan blade, a heat dissipation hole is opened on the end cover to facilitate the air flo...
