Abstract
The purpose present invention is to provide an air refrigerant type cooling apparatus provided with an internal air cooling mechanism with high reliability and efficiency. Another object of the present invention is to provide an air refrigerant cooling/heating system with a simplified configuration using the air refrigerant type cooling apparatus. To accomplish the purpose, a heat radiating means is provided in a motor of an air refrigerant type cooling apparatus having a compressor, the motor and an expansion turbine in the present invention. Also, a pressure difference is positively generated between the inside and outside of the motor. By these means, when the motor is driven, the heat from the stator main body is exhausted to the outside of the motor through the heat radiating means and the heat from the coil end portions is exhausted through the cooling air exhausted from the inside to the outside of the motor. Further, a guide plate is located adjacent to the cooling air inlet in the motor, so that the intake cooling air is efficiently guided to the stator coil end portions. By this means, the heat generated from the coil end portions is efficiently exhausted from the inside to the outside of the motor. According to these configurations, an air refrigerant cooling apparatus can be realized. Moreover, by installing the air refrigerant cooling apparatus to a cooling/heating system, an air refrigerant cooling/heating system having simple configuration and very high reliability can be provided.
