ABSTRACT:
In the embodiment disclosed in the specification an evaporation cooling system for an internal combustion engine heat exchanger avoids valves or the like by providing a liquid-vapor separator in the vapor line between the engine and the main condenser and a bypass line for liquid coolant which bypasses the main condenser leading to a condensate line having a pump. When the temperature of the engine is high enough for coolant to vaporize, the vapor passes through the vapor line and the separator to the main condenser. A heat exchanger for a vehicle heater is disposed in the condensate line so that it always receives all of the coolant in circulation.
