ABSTRACT:
The cooling of a hot fluid is effected using a heat exchanger adapted to receive the hot fluid and liquid coolant for cooling the hot fluid such that the liquid coolant is vaporized. A turbine, having an output shaft connected to a fan, is responsive to vaporized coolant which expands in the turbine for driving the fan to move a mass of air, and produce vaporized coolant. A condenser receives the expanded vaporized coolant and is responsive to air blown by the fan, for condensing the expanded vaporized coolant thereby cooling the same and producing coolant condensate which is then returned to the heat exchanger.
