Date Apr. 10, 1986.Recirculating coolant from an engine passes through tubes in a heat exchanger pressure vessel. A cooling medium is directed onto the exterior surfaces of the tubes, and the pressure within the vessel is reduced to lower the temperature of evaporation of the cooling medium. A thermostatic control reduces or prevents the flow of engine coolant to the tubes when the coolant temperature falls below the temperature of evaporation of the cooling medium. |
