Abstract

The invention provides a phase-change heat dissipation motor shell and a motor applying the same. The phase-change heat dissipation motor shell comprises a motor body and a motor shell, wherein the motor body comprises a rotor assembly, a rotating shaft and a stator assembly; one end of the rotating shaft is fixedly connected with the rotor assembly through a bearing; the rotor assembly is arranged in the stator assembly in a sleeved mode; the stator assembly is arranged inside the motor shell in a sleeved mode; and spiral phase-change cooling fins are fixedly connected to the surface of the stator assembly. The invention relates to the field of motors. According to the phase-change heat dissipation motor shell and the motor applying the same, the integrated spiral heat dissipation structure is used, and compared with an existing independent heat dissipation fins, the flowing space of the phase-change working medium is large, the heat dissipation continuity is enhanced, and meanwhile,the heat dissipation effect of the traditional fan-shaped heat fins is enhanced on the basis, and the consumable material of the machine shell is saved, so that the problems that the heat dissipationcontinuity of a common phase-change heat dissipation motor is poor, the heat dissipation effect is continuously reduced along with the increase of temperature, and the phase-change working medium is poor in liquidity and small in space elasticity and phase-change working medium loss occurs easily can be solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a phase-change heat dissipation motor casing and a motor applied thereto. Background technique [0002] The current heat dissipation method of the motor is mainly that the surface of the motor casing is provided with heat dissipation fins, the heat of the motor components is transferred to the motor casing through the heat transfer medium, and then the heat dissipation fins of the casing gather the heat and dissipate it to achieve heat dissipation. The effect of this kind of heat dissipation is relatively common. In order to achieve a good heat dissipation effect, it is necessary to expand the heat dissipation area. Therefore, such a motor casing is set larger, and the heat transfer effect is poor after heat balance. Heat dissipation, but the fluidity of the phase change working medium is poor in a small space, and the heat dissipation efficiency is low, and when the phase change ...
