冷却装置。In a water-cooled engine equipped with a water pump, a bypass is provided that is connected to a discharge side and a suction side of the water pump, and a bypass is provided at a branch point between the flow path from the discharge side of the water pump to the engine and the bypass. When the temperature of the cooling water is low, part of the cooling water is passed through the engine and returned to the intake side of the water pump through the bypass, whereas when the temperature of the cooling water is high, the entire amount of the cooling water is A thermovalve is disposed to allow the heat to flow to the engine, and a heat exchanger is disposed in the middle of the bypass to absorb exhaust heat from the engine and heat cooling water in the bypass.
