Abstract
본 발명은 팬구동 제어장치에 관한 것으로서, 전자기기가 구동중에 발생되는 열을 감지하여 이 열에 대응되는 온도 감지 신호를 출력하는 온도감지부와; 서로 상이한 값을 갖는 다수개의 PWM 신호들이 저장되어 있으며, 상기 온도감지부의 온도 감지 신호에 대응하는 PWM 신호를 선택적을 출력하는 제어부와; 상기 제어부의 PWM 신호를 저대역으로 필터링하여 PWM 신호의 펄스폭에 대응하는 전압을 출력하는 저대역 필터부와; 상기 저대역 필터부의 필터링 신호에 대응하는 전원 전압을 출력하는 전원 공급부와; 상기 전원공급부의 전원전압에 대응하는 속도로 회전하여 전자기기 내부의 열을 대기중으로 방사시키는 팬모터 구동부를 포함한다. 따라서, 본 발명은 감지된 온도에 비례하여 팬의 구동속도를 제어하여 전자기기내의 온도를 정확하게 조절할 수 있다.The present invention relates to a fan driving control device, comprising: a temperature sensing unit for sensing heat generated while an electronic device is driven and outputting a temperature sensing signal corresponding to the heat; A control unit for storing a plurality of PWM signals having different values from each other and selectively outputting a PWM signal corresponding to the temperature sensing signal of the temperature sensing unit; A low band filter unit filtering the PWM signal of the controller to a low band and outputting a voltage corresponding to the pulse width of the PWM signal; A power supply unit outputting a power supply voltage corresponding to the filtering signal of the low band filter unit; And a fan motor driving unit which rotates at a speed corresponding to the power voltage of the power supply unit to radiate heat inside the electronic device to the atmosphere. Therefore, the present invention can accurately control the temperature in the electronic device by controlling the driving speed of the fan in proportion to the sensed temperature.
