Patent ID: 7954332

Claim:
A system for controlling the temperature of heat producing equipment, comprising: a sealed housing for the heat-producing equipment, the heat-producing equipment comprising variable speed drive system equipment sized for submersible pump applications in the oil, gas, and petrochemical industries; a vented housing for receiving heat from within the sealed housing and configured for facilitating transfer of received heat to air within the vented housing and for transfer of the heated air to the exterior though one or more air vents in the walls of the vented housing; a heat sink system in physical contact with the heat producing equipment for passively and conductively transferring heat without liquids or coolants directly from the equipment into the air within the vented housing; a thermoelectric assembly in indirect thermal association with the heat producing equipment for actively transferring heat from air within the sealed housing into the vented housing; a power control system operatively connected to the thermoelectric assembly for activating the thermoelectric assembly to obtain a predetermined temperature; and a sensor operatively connected to the power control system to provide an input to the power control system indicative of the temperature within the sealed housing.
