摘要： PROBLEM TO BE SOLVED: To provide a cooling device for a vehicle, which accurately adjusts the opening of a valve mixing the cooling water in a first cooling water circuit and the cooling water in a second cooling water circuit to an appropriate value according to the actual discharge flow rate of cooling water from a pump with good response in a simple structure.
SOLUTION: A relief valve 7 is used as the valve mixing the cooling water of a bypass route in the first cooling water circuit with the cooling water in the second cooling water circuit. The relief valve 7 includes a valve element 9 energized to a valve close direction by the elastic force of a spring 8 and a receiving force based on the pressure difference between the pressure on its own upstream side and the pressure on a downstream side in a valve open direction. Thus, the relief valve 7 which is closed will be opened by increasing the discharge flow rate of the water pump 3 so as to keep the force acting on the valve element 9 in the valve open direction based on the pressure difference between the pressure on the upstream side of the relief valve 7 and the pressure on the downstream side larger than the force acting on the valve element 9 in the valve close direction by elastic force of the spring 8.
