PURPOSE: A cooling system for an engine of a vehicle using an evaporating heat of a refrigerant is provided to reduce the consumption of energy for driving a water pump by adapting a natural cooling system. CONSTITUTION: A cooling system for an engine of a vehicle comprises an engine coolant water jacket(10), a condenser(11), a gas line(12), a liquid pipe(13), a gas extrusion part(15), a liquid inlet(16), a liquid outlet(14) and a cooling control valve(17). The engine coolant water jacket is formed in the engine body in order to surround the engine. The engine coolant water jacket has a coolant circulation path for circulating refrigerant. The condenser has the coolant circulation path. A gas line connects the top withdrawal pipe of the engine coolant water jacket and the top withdrawal pipe of the condenser in order to be mutually connected. The liquid pipe connects the lower withdrawal pipe of the engine coolant water jacket and the lower withdrawal pipe of the condenser in order to be mutually connected. The gas extrusion part discharges internal air to the top conduit line one side of the gas line. The liquid inlet injects the liquid coolant into the top conduit line one side of the liquid pipe. The liquid outlet leaks the liquid coolant of the cooling system to the lower conduit line one side of the liquid pipe. The cooling control valve controls the cooling performance. The cooling control valve is installed on the gas line in order to take a thermostat role. |
