Description
본 발명은 차량의 냉각팬 점검 장치 및 방법에 관한 것으로서, 특히 차량의 냉각팬의 작동상태를 점검하여 고장으로 판단되는 경우에 경고하여 주기 위한 차량의 냉각팬 점검 장치 및 방법에 관한 것이다.The present invention relates to an apparatus and a method for checking a cooling fan of a vehicle, and more particularly, to an apparatus and a method for checking a cooling fan of a vehicle for checking an operating state of a cooling fan of a vehicle to warn of a failure.
일반적으로, 냉각팬은 금속편 또는 합성수지를 성형한 날개를 회전시켜 라디에이터로 통풍하여 이것을 냉각한다. 워터펌프와 같은 축에 설치한 풀리(pulley)로 구동시키는 것과 엔진과 분리한 위치에 설치하여 냉각팬 모터로 구동시키는 것이 있다. 라디에이터로 냉각수가 순환할 때 공기를 빨아들여 냉각 효과를 증대하며 배기 다기관의 과열도 방지한다. 냉각 팬의 비틀림 각도는 20∼30°이며 4∼6개의 날개가 설치되어 있다.In general, a cooling fan rotates the blades formed of metal pieces or synthetic resins, and ventilates them to radiators to cool them. It is driven by a pulley installed on the same shaft as the water pump and by a cooling fan motor in a position separated from the engine. As the radiator circulates coolant, it draws in air to increase the cooling effect and prevent overheating of the exhaust manifold. The torsion angle of the cooling fan is 20 to 30 degrees, and 4 to 6 wings are provided.
