PURPOSE:To make the temperature in a system follow the objective temperature without being effected by external turbulence such as car running wind by controlling, to rise and drop, a coolant level in a condenser in which coolant boiled in a water jacket is cooled and condensed. CONSTITUTION:Liquid phase coolant in a water jacket 1 cools respective parts of an engine when it is boiled, and the coolant steam is condensed in a condenser 2 and stored temporarily in the lower portion of the condenser 2. When a coolant level in the water jacket 1 is dropped, coolant is replenished from the condenser or a reservoir tank 5 by control of a water jacket side liquid level control means 14. In this system, when a detected temperature is higher than the objective temperature, the coolant level in the condenser 2 is dropped by control of a coolant supply pump 4 etc. by a condenser side liquid level control means 16. In the inverse case, an opening and closing means 7 is opened to raise the liquid level in the condenser 2. |
