Abstract:
1. A cooling apparatus for an internal combustion engine, comprising: an electric water pump that circulates a coolant in a cooling pipe provided in an internal combustion engine; a radiator that radiates heat of the coolant; an electric fan that cools the radiator; a control device that controls the electric water pump and the electric fan; and first flow rate correction portion, wherein: the control device controls a discharge flow rate of the electric water pump based on a target flow rate set according to an amount of heat generated in the internal combustion engine, and controls operation of the electric fan based on a temperature of the coolant; the first flow rate correction portion sets a lower limit value of the discharge flow rate based on the temperature of the coolant; and the first flow rate correction portion increases the lower limit value of the discharge flow rate in accordance with an increase in the temperature of the coolant, when the temperature of the coolant is equal to or higher than an operation temperature at which the operation of the electric fan is started.
