Abstract:
A cooling apparatus includes an electric water pump that circulates a coolant, a radiator that radiates heat of the coolant, an electric fan that cools the radiator, a control device, and first flow rate correction means. The control device controls the discharge flow rate of the electric water pump based on a target flow rate set based on an amount of heat generated in an engine, and controls operation of the electric fan based on a coolant temperature. When the coolant temperature is equal to or higher than a fan operation temperature at which the operation of the electric fan is started, the first flow rate correction means increases the discharge flow rate of the electric water pump in accordance with an increase in the coolant temperature.
