Abstract
본 발명은 자동차의 냉각팬 제어장치에 관한 것으서, 종래의 대부분 차량에 적용되어 설치된 냉각 팬 장치는 서머스위치에 의하여 냉각 팬이 작동하게 되어 있어 냉각수 온도센서와 함께 불필요한 스위치를 사용하여야 하며 동작시 엔진의 RPM변화에 의한 드롭현상을 유발하게 하는 문제점이 있었다. 냉각수 온도센서(10)의 신호를 입력받는 ECU(20)가 팬 컨트롤 회로부(30)를 내장하여 설치되고, 상기 ECU(20)의 팬 컨트롤 회로부(30)는 라이에터 냉각팬(40)을 자동 제어할 수 있게 구성된다. 따라서, 본 발명을 이용한 자동차는 냉각수 온도센서의 신호가 직접 ECU에 입력되어 ECU에 의한 냉각 팬이 자동 제어 되므로 회로가 간단하여 지며, 엔진;의 드롭 현상의 방지와 냉각수 온도 상승에 따른 냉각 팬의 속도를 자동 조절할 수 있게 하는 효과가 있다.The present invention relates to a cooling fan control device of a vehicle, the cooling fan device is applied to most conventional vehicles installed in the cooling fan is operated by the thermal switch to use the unnecessary switch with the coolant temperature sensor during operation There was a problem that causes the drop phenomenon by the RPM change of the engine. The ECU 20 receiving the signal from the coolant temperature sensor 10 is installed with a fan control circuit unit 30 built therein, and the fan control circuit unit 30 of the ECU 20 controls the lighter cooling fan 40. It is configured for automatic control. Accordingly, in the vehicle using the present invention, the signal of the coolant temperature sensor is directly input to the ECU, and the cooling fan by the ECU is automatically controlled, thereby simplifying the circuit, preventing the drop phenomenon of the engine; It has the effect of automatically adjusting the speed.
