Patent ID: 7735326

Claim:
A cooling system for electronic equipment, comprising: an enclosure housing a plurality of heat-generating electronic components, the enclosure having an enclosure inlet for receiving air and an enclosure outlet for exhausting heated air; a first air pathway and a second air pathway separated by a distance within the enclosure; a thermoelectric cooling module configured such that a first side is cooled and a second side is heated in response to an applied voltage; a first heat exchanger disposed in the first air pathway and in thermal contact with the first side of the thermoelectric cooling module; a second heat exchanger disposed in the second air pathway and in thermal contact with the second side of the thermoelectric cooling module; a temperature sensor disposed within the enclosure and in electrical communication with a voltage regulator; and wherein the voltage regulator is configured for varying the voltage to the thermoelectric cooling module in response to temperature sensed by the temperature sensor.
