Abstract
A cooling apparatus for cooling an internal combustion engine having a coolant passing through the engine is provided. A heat exchanger performs a heat-energy exchange and a heat exchanger bypass passage prevents part of the coolant flowing out from the engine from flowing into the heat exchanger. A coolant combination device forms a mix of coolant which flows in a passage bypassing a thermostat with coolant which flows in a passage through the thermostat, while a flow rate ratio adjusting valve continuously adjusts the ratio of the flow rate of the part of the coolant which bypasses the thermostat to the part of the coolant which passes through the thermostat in accordance with a temperature of the coolant. Accordingly, the higher the temperature is, the larger the ratio is. Moreover, the temperature is controlled in accordance with a load of the engine so that the larger the load is, the higher the temperature is.
