Abstract

본 발명은 라디에이터의 통풍을 돕는 냉각팬에 관한 것으로, 라디에이터를 통과한 냉각수온에 따라 냉각팬의 회전속도를 다단으로 제어하여 냉각팬에 의한 소음을 적게 하기 위한 것으로, 라디에이터(1) 후방에 장착된 냉각팬(2)을 작동시키는 전동모터(3)와; 라디에이터(1)를 통과한 냉각수의 온도를 검출하는 수온센서(4)와; 상기 수온센서(4)로부터 입력된 냉각수온이 규정온도 이상인 동안 전동모터(3)를 작동시켜서 냉각팬(2)을 회전시키는 엔진제어부(10)로 이루어진 냉각팬 제어장치에 있어서, 상기 엔진제어부(10)는 상기 수온센서(4)로부터 입력되는 냉각수온이 제1설정온도 이상인 경우 전동모터(3)를 2단으로 고속회전시키고, 상기 냉각수온이 제2설정온도 이상이면서 제1설정온도 보다 작은 경우 상기 전동모터(3)를 1단으로 저속회전시키는 것을 특징으로 소음 저감을 위한 냉각팬에 제어방법이다.The present invention relates to a cooling fan for facilitating the ventilation of a radiator and is designed to control the rotation speed of the cooling fan in multiple stages according to the cooling water temperature through the radiator so as to reduce noises generated by the cooling fan. An electric motor 3 for operating the cooling fan 2; A water temperature sensor (4) for detecting the temperature of the cooling water that has passed through the radiator (1); And an engine control unit (10) for rotating the cooling fan (2) by operating the electric motor (3) while the cooling water temperature inputted from the water temperature sensor (4) 10) rotates the electric motor (3) in two stages at a high speed when the cooling water temperature inputted from the water temperature sensor (4) is equal to or higher than the first set temperature, and when the cooling water temperature is higher than the second set temperature , The electric motor (3) is rotated in one step at a low speed, thereby controlling the cooling fan for noise reduction.
