본 발명의 실시예에 따른 냉각수 제어 밸브유닛을 구비한 엔진 냉각시스템은, 실린더 블럭 위에 배치되는 실린더 헤드, 상기 실린더 헤드의 냉각수출구 측에서 냉각수를 공급받고, 히터와 라디에이터로 분배되는 냉각수를 제어하고, 상기 실린더 블럭에서 배출되는 냉각수를 제어하는 냉각수 제어 밸브유닛, 및 운행조건에 따라서 난방우선모드를 판단하고, 상기 난방우선모드에서 상기 냉각수 제어 밸브유닛을 제어하여 상기 히터에 대응하는 제1 냉각수 통로를 최대로 개방하는 제어유닛을 포함할 수 있다.

    An engine cooling system has a coolant control valve unit and includes a cylinder head disposed on a cylinder block. The coolant control valve unit is configured to receive coolant from a coolant outlet side of the cylinder head to control coolant distributed to a heater and a radiator and to control coolant exhausted from the cylinder block. A control unit is configured to determine a heating priority mode according to operation conditions and to substantially open a first coolant passage corresponding to the heater by controlling the coolant control valve unit in the heating priority mode.
