ABSTRACT:
A hermetically sealed compressor has a fan for cooling the motor of the compressor. The compressor utilizes the refrigerant vapor inside the hermetic shell to cool the motor. The fan is attached to the end of the motor rotor and crankshaft to circulate the suction gas of the compressor around and through the motor rotor and motor stator to absorb heat and then directs the suction gas against the hermetic shell in a spiralling motion for transferring heat to the shell which in turn transfers heat to the atmosphere.
