먼저, 온도센서(175)로부터의 온도가 소정의 설정 상한치 이상으로 되면 상기 제어유닛(144a)는 크로스팬구동부(144c)를 제어하여 크로스 팬(146)이 회전하여 공기 흡입 슬릿부(132)를 통하여 외부공기가 유입되어 통풍공간(172)와 통풍구(153) 및 복수의 내부 슬릿부(135)를 경유하여 공기배출 슬릿부(134)로 배출되도록 함으로써 엘씨디 보드(164)와 엘씨디 패널(162)의 방열을 수행하여, 엘씨디 모니터 자체에서 발생하는 열을 효율적으로 방열한다. 여기서, 소정의 설정 상한치를 초과하는 초과 온도량에 따라서 크로스 팬(146)의 속도를 제어하여 유입되는 공기 량을 제어하도록 하여도 된다.First, when the temperature from the temperature sensor 175 is greater than or equal to a predetermined set upper limit, the control unit 144a controls the cross fan driving unit 144c so that the cross fan 146 rotates to move the air intake slit unit 132. External air is introduced through the discharge space 172, the vent 153, and the plurality of internal slit portions 135 so as to be discharged to the air discharge slit portion 134 by the LCD board 164 and the LCD panel 162. By conducting heat radiation, the heat generated by the LCD monitor itself is effectively radiated. Here, the speed of the cross fan 146 may be controlled according to the amount of excess temperature exceeding a predetermined set upper limit so as to control the amount of air introduced therein.
한편, 온도센서(175)로부터의 온도가 소정의 설정 하한치 이하로 되면 상기 제어유닛(144a)는 히터구동부(144d)를 제어하여 히터(149)를 구동하고 크로스팬구동부(144c)를 제어하여 크로스 팬(146)이 회전하여 공기 흡입 슬릿부(132)를 통하여 외부공기가 유입되어 히터(149)에 의하여 가열된 상태로 통풍공간(172)과 통풍구(153) 및 내부 슬릿부(135)를 경유하여 공기배출 슬릿부(134)로 배출되도록 함으로써 엘씨디 보드(164)와 엘씨디 패널(162)이 얼지 않도록 한다. 여기서, 소정의 설정 하한치를 밑도는 온도량에 따라서 히터(149)의 가열 온도를 제어하여 유입되는 공기의 가열 량을 제어하도록 하여도 된다.On the other hand, when the temperature from the temperature sensor 175 is less than or equal to a predetermined lower limit, the control unit 144a controls the heater driver 144d to drive the heater 149 and controls the cross fan driver 144c to cross it.

Here, the heating amount of the introduced air may be controlled by controlling the heating temperature of the heater 149 according to the temperature amount below the predetermined set lower limit.
한편, 조도센서(176)로부터의 조도가 소정의 설정치 이상으로 되면 상기 제어유닛(144a)는 크로스팬구동부(144c)를 제어하여 크로스 팬(146)이 회전하여 공기 흡입 슬릿부(132)를 통하여 외부공기가 유입되어 통풍공간(172)과 통풍구(153) 및 내부 슬릿부(135)를 경유하여 공기배출 슬릿부(134)로 배출되도록 함으로써 엘씨디 보드(164)와 엘씨디 패널(162)의 방열을 수행하여, 직사광선의 적외선 조사에 의하여 엘씨디 패널 온도가 상승을 방지하여 엘씨디 모니터 패널의 흑화현상을 방지할 수 있게 된다. 여기서, 소정의 설정치를 초과하는 초과 조도량에 따라서 크로스 팬(146)의 속도를 제어하여 유입되는 공기 량을 제어하도록 하여도 된다.On the other hand, when the illuminance from the illuminance sensor 176 is more than a predetermined set value, the control unit 144a controls the cross fan driving unit 144c so that the cross fan 146 rotates through the air intake slit unit 132. External air flows into the air discharge slit part 134 via the ventilation space 172, the ventilation hole 153, and the inner slit part 135 to prevent heat dissipation of the LCD board 164 and the LCD panel 162. As a result, the LCD panel temperature is prevented from rising by direct infrared ray irradiation to prevent blackening of the LCD monitor panel. Here, the amount of air flowing in may be controlled by controlling the speed of the cross fan 146 according to the excess illuminance amount exceeding a predetermined set value.
한편, 습도센서(177)로부터의 온도가 소정의 설정치 이상으로 되면 상기 제어유닛(144a)은 히터구동부(144d)를 제어하여 히터(149)를 구동하고 크로스팬구동부(144c)를 제어하여 크로스 팬(146)이 회전하여 공기 흡입 슬릿부(132)를 통하여 외부공기가 유입되어 히터(149)에 의하여 가열된 상태로 통풍공간(172)과 통풍구(153) 및 내부 슬릿부(135)를 경유하여 공기배출 슬릿부(134)로 배출되도록 함으로써 엘씨디 보드(164)와 엘씨디 패널(162) 주위의 습도가 낮아지도록 한다. 여기서, 소정의 설정치를 초과하는 습도량에 따라서 히터(149)의 가열 온도를 제어하여 유입되는 공기의 가열 량을 제어하도록 하여도 된다.On the other hand, when the temperature from the humidity sensor 177 is higher than a predetermined set value, the control unit 144a controls the heater driver 144d to drive the heater 149 and controls the cross fan driver 144c to cross-fan. 146 is rotated so that the outside air flows through the air intake slit 132 and is heated by the heater 149 via the ventilation space 172, the vent 153, and the inner slit 135. By allowing the air discharge slit 134 to be discharged, the humidity around the LCD board 164 and the LCD panel 162 is lowered. In this case, the heating amount of the introduced air may be controlled by controlling the heating temperature of the heater 149 according to the humidity amount exceeding a predetermined set value.
