Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Such as figure 1 The shown motor includes a casing 1, and a motor chamber 2 is formed in the casing 1, a stator and a rotor are arranged in the motor chamber 2, a refrigerant inlet 3 and a refrigerant outlet 4 are arranged on the motor chamber 2, The refrigerant enters the motor cavity 2 from the refrigerant inlet 3 for heat exchange, and is discharged from the motor cavity 2 through the refrigerant outlet 4, and the refrigerant directly enters the motor cavity 2 to directly exchange heat inside the motor , thereby effectively overcoming the problem of low heat exchange efficiency caused by...

Abstract

The invention provides a motor with a cooling structure and a rotary compressor. The motor comprises a shell, a motor cavity is formed in the shell, a refrigerant inlet and a refrigerant outlet are formed in the motor cavity, and a refrigerant enters the motor cavity from the refrigerant inlet for heat exchange and is discharged out of the motor cavity from the refrigerant outlet. According to the motor with the cooling structure and the rotary compressor provided by the invention, the refrigerant inlet and the refrigerant outlet are formed in the motor cavity, and a refrigerant is directly introduced into the motor cavity for cooling, so the heat dissipation effect of the motor is effectively improved, and the problem that the motor is burnt and damaged due to too high temperature is further avoided; the temperature detection mechanism can detect the internal temperature of the motor, and the heat dissipation rate of the refrigerant to the motor is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of driving mechanisms, in particular to a motor and a rotary compressor with a cooling structure. Background technique [0002] As the driving power of the centrifugal compressor, the motor is the core component of the compressor, and the performance of the motor directly affects the cooling effect of the compressor. When the motor is running, various losses will be generated, and these losses will be converted into heat energy to increase the temperature of various parts of the motor. The mechanical, electrical, and physical properties of the materials used in the motor winding insulation system gradually deteriorate with the increase of temperature. When the temperature rises to a certain level, the insulation system loses its insulation ability and causes the motor to burn or burn out. In order to ensure the stable operation of the motor and improve the performance of the motor, the cooling and heat diss...
