PROBLEM TO BE SOLVED: To provide an engine cooling system capable of improving the performance of a Rankine cycle while suppressing an increase in the weight of a vehicle with the Rankine cycle mounted thereon.SOLUTION: The engine cooling system includes a Rankine cycle 31 where refrigerant 30 circulates through a refrigerant pump 25, an evaporator 26, an expander 28 and a condenser 29 in sequence, an engine body 10 having a turbocharger 6 provided in an intake passage 5, and a radiator 3 where engine body cooling water 18 circulates. A sub radiator 2 is installed in parallel to the radiator 3. Compressed air 8 compressed by the turbocharger 6 is used as a heating source for the evaporator 26, and outlet side cooling water 32 in the sub radiator 2 is used as a cooling source for the condenser 29. |
