Thermal system having electrical device

摘要

A thermal system is disclosed in thermal communication with an electrical device. In one form the thermal system is a refrigeration system. The electrical device can be disposed within the refrigeration system such that a working fluid of the refrigeration system exchanges heat with the electrical device. In one embodiment the refrigeration system includes a container in which the electrical device is disposed. The electrical device can be an electrical motor, but other forms are contemplated. The container can be located anywhere in the thermal system. In one non-limiting embodiment the working fluid of the refrigeration system wets a stator of the motor. A partition can be used to separate the stator from the motor to keep the motor free from working fluid.

主权项

1. An apparatus comprising:
a refrigeration fluid receiving vessel for receiving a volume of refrigerant in a cyclic refrigeration system, the vessel having a first opening to receive the refrigerant from a first portion of a refrigeration system and a second opening to deliver the refrigerant to a second portion of the refrigeration system; and an electrical motor includes a rotor and a stator and the electric motor is at least partially contained within the refrigeration fluid receiving vessel; a partition located between the stator and the rotor; and wherein the stator is immersed in the refrigerant such that refrigerant is located between conductive windings of the stator and the partition acts to isolate the rotor from the refrigerant such that the rotor is not contacted by refrigerant.
