Abstract
A cooling device for an internal combustion engine has an outflow temperature sensor, a flow control valve, and a control device. The outflow temperature sensor detects an outflow temperature of the cooling water flowing out from a cooling-water outlet of the internal combustion engine. The flow control valve adjusts a flow rate of the cooling water flowing in a bypass passage. The control device controls the flow control valve to be open or closed. The control device, during a warming of the internal combustion engine, controls the flow control valve to be open or closed based on information about a change rate of the outflow temperature to prevent the change rate of the outflow temperature from decreasing to a minus value, after opening the flow control valve and starting a circulation of the cooling water in a route passing through the bypass passage.
