Description

technical field [0001] The invention relates to the technical field of motors, in particular to an integrated heat dissipation motor system. Background technique [0002] At present, the commonly used heat exchange methods for high-speed motors include air heat exchange, coolant heat exchange, and evaporation heat exchange. Although the effect of evaporative heat exchange is the best, it is difficult to maintain. For the blower fan, it is necessary to add a refrigerant circulation system, which is not economical; for the heat exchange of air alone, the heat exchange is difficult to meet the requirements; for the high-power magnetic levitation centrifugal drum The compressor still mainly uses coolant heat exchange and air heat exchange at the same time, in which the coolant flows in the cooling channel in the motor housing to bring out the heat of the stator winding, and the air is between the magnetic suspension bearing, the sensor, the rotor and the stator It flows in the ...

Although the effect of evaporative heat exchange is the best, it is difficult to maintain. For the blower fan, it is necessary to add a refrigerant circulation system, which is not economical; for the heat exchange of air alone, the heat exchange is difficult to meet the requirements; for the high-power magnetic levitation centrifugal drum The compressor still mainly uses coolant heat exchange and air heat exchange at the same time, in which the coolant flows in the cooling channel in the motor housing to bring out the heat of the stator winding, and the air is between the magnetic suspension bearing, the sensor, the rotor and the stator It flows in the gaps to bring out the internal heat of the components; however, in the conventional structure, an additional blower or induced draft fan needs to be installed on the air side to realize the air flow, and the heat exchanger connected to the cooling liquid side also needs to be installed with a fan to achieve Air-cooled, complex structure, high energy consumption, loud noise
