Abstract
The present invention relates to a cooling controller for cooling an internal-combustion engine such as an internal-combustion engine for an automobile, comprising a temperature detector for detecting the temperature of the cooling medium placed in a first or second circulation channel, and a flow control for controlling the flow of the cooling medium placed in the first or second circulation channel. The first circulation channel passes through the engine and the radiator as in a conventional cooling system. The second circulation channel, which is used in case of a detected failure of the radiator or thermostat valve, includes the heat exchanger of the automobile's air-conditioning system. When the failure is detected an air conditioner controller maximizes the amount of heat radiated from the air conditioning exchanger to prevent overheating.
