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.
