Motor cooling system and cooling method

Abstract

The invention discloses a motor cooling system and a cooling method, and belongs to the technical field of motors. The cooling system comprises a motor shell, a liquid inlet pipeline, a liquid return pipeline and a radiator, the motor shell is provided with a plurality of cooling chambers, the cooling chambers are filled with cooling media, the liquid inlet pipeline is communicated with the liquid inlet ends of the cooling chambers, the liquid return pipeline is communicated with the liquid outlet ends of the cooling chambers, the liquid outlet end of the radiator is communicated with the liquid inlet pipeline, and the liquid inlet end is communicated with the liquid return pipeline. And a cooling medium enters the cooling chamber of the motor shell from the liquid inlet pipeline and then enters the radiator from the liquid return pipeline for heat dissipation. The cooling chambers are formed in the motor shell, heat of the motor shell is brought into the radiator through the cooling medium for heat dissipation, the cooling efficiency of the motor in the sealed space can be improved, and the problems that in air cooling heat dissipation, the heat dissipation capacity in the sealed space is poor, and the heat dissipation efficiency is poor are solved. And the problem that a high-power motor in the electric automobile is damaged due to overheating when working in a sealed space for a long time is solved.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a motor cooling system and a cooling method. Background technique [0002] The cooling of the existing motor is mainly through the cooling fins on the side wall of the housing. This method uses air cooling to dissipate heat, which has the problem of poor heat dissipation in the sealed space, especially for high-power motors in electric vehicles that work for a long time in the sealed space. There is a problem of overheating damage, so it is necessary to provide a motor cooling system that can improve the cooling efficiency of the motor in the sealed space. Contents of the invention [0003] Purpose of the invention: to provide a motor cooling system and a cooling method to solve the above-mentioned problems in the prior art. [0004] Technical solution: The motor cooling system includes: the motor housing, which is provided with several cooling cavities filled with cooling medi...
