ABSTRACT:
An electro-mechanical device having an integral reflux-type cooler configured to conduct heat generated in a first member of the electro-mechanical device to a heat sink, while not exposing a second member of the device to refrigerant in the reflux cooler is provided. In some embodiments of the invention, the refrigerant is allowed to directly contact electrical windings, or a magnetic core of the electro-magnetic device for maximizing heat transfer. Other embodiments of the invention provide integral phase change material for heat storage capability, and allow flexibility in mounting the condenser of the reflux cooler remotely from the electro-mechanical device.
