Abstract

The invention discloses a direct spray-type motor cooling system which comprises a radiator, an oil pump, a fine filter, a drier, nozzles, an oil sump and a coarse filter. There are a plurality of nozzles. The radiator, the oil pump, the fine filter and the drier are successively connected through pipelines. The drier is connected with the plurality of nozzles through pipelines. The plurality of nozzles are arranged on a motor shell. At least one nozzle is communicated with an internal rotor or stator on the inner side of a motor, and at least another nozzle is directly facing a stator or rotor shell on the outside of the motor. The inner end at the bottom of the motor shell is provided with the oil sump which is connected with the coarse filter. The coarse filter is connected with the radiator. According to the invention, a motor stator (rotor) winding can be directly sprayed with a cooling medium, and the type of the motor and the position of the rotor are unlimited. The cooling medium can be used to lubricate rolling bearings or sliding bearings in the motor. Thus, the motor winding can be cooled effectively, and cooling and lubrication system integration of the motor also can be realized. The system provided by the invention has advantages of low cost, good cooling effect and the like.

Description

technical field

[0001] The invention relates to a motor cooling system, in particular to the motor cooling system working in the manner of directly spraying cooling medium to the stator (rotor) of the motor. Background technique

[0002] With the increasing tension of fossil energy and environmental problems, electric vehicles are getting more and more attention. In order to meet the driving requirements of electric vehicles, the driving motor needs to have a higher power density, which will make the motor heat more serious. Therefore, an efficient motor winding cooling solution has become an urgent need for the development of electric vehicle driving motors.

[0003] At present, the cooling methods of motor windings are mainly air cooling and circulating water cooling. The cooling effect of air cooling increases as the fan speed increases, but the higher the fan speed, the greater the resistance, which will reduce the overall efficiency of the motor and easily cause vibrat...
