PROBLEM TO BE SOLVED: To provide a cooling device for an internal combustion engine enabling early start of exhaust gas recirculation.SOLUTION: A cooling device 1 for an internal combustion engine includes a body cooling passage 11 that passes through an engine body. The cooling device 1 for the internal combustion engine includes: a supercharger cooling passage 21 that is connected to the body cooling passage 11 and passes through a turbine housing of a supercharger; and a recirculation path cooling passage 23 that passes through a cooler for exhaust gas recirculation. The cooling device 1 for the internal combustion engine includes: a communication cooling passage for communicating an outlet of the supercharger cooling passage 21 with an inlet of the recirculation path cooling passage 23; and a passage control valve 40 disposed on the communication cooling passage. The cooling device 1 for the internal combustion engine includes a control device 50 that outputs a command signal for communication of the communication cooling passage to the passage control valve 40 when a temperature of cooling water of the engine body is less than a predetermined temperature. |
