The flap door main body is hinged to the side panel 10 of the side to open and close in a hinged manner, 12 is a flap door panel, the flap door panel 12 has a predetermined cross-sectional area in the longitudinal and horizontal intervals The distribution hole 13 is formed.

20은 에어유통공 가변수단으로서, 상기 에어유통공 가변수단(20)은 상기 플랩 도어 패널(12)의 내측면에 슬라이딩 패널(21)을 슬라이딩할 수 있게 지지하고, 상기 슬라이딩 패널(21)에 상기 에어유통공(13)과 동일간격으로 에어 제어 유통공 (22)을 형성하여 슬라이딩시킴으로써 에어유통공(13)의 에어유통 단면적을 증감하고, 상기 슬라이딩 패널(21)의 일측에 유체실린더(23)의 피스톤 로드(25)를 연결함과 아울러 그 실린더 본체(24)의 양측에 유체도관(25a)(25b)을 연결하여 상기 유체도관(25a)(25b)을 통합하여서 솔레노이드 밸브(26)를 설치한 것이다.20 is an air distribution hole variable means, and the air distribution hole variable means 20 supports the sliding panel 21 on the inner side of the flap door panel 12 so as to be slidable, and supports the sliding panel 21. By forming and sliding the air control distribution hole 22 at the same interval as the air distribution hole 13, the air flow cross-sectional area of the air distribution hole 13 is increased or decreased, and the fluid cylinder 23 is disposed at one side of the sliding panel 21. The solenoid valve 26 is connected by connecting the piston rod 25 of the &lt; RTI ID = 0.0 &gt;) &lt; / RTI &gt; and connecting the fluid conduits 25a and 25b to both sides of the cylinder body 24 to integrate the fluid conduits 25a and 25b. It is installed.

상기 슬라이딩 패널(21)은 상기 플랩 도어 패널(12)의 내측면의 상하에 일정간격을 두고 레일(28a)(28b)을 설치하여 상하를 지지함으로써 슬라이딩 패널(21)의 지지가 간단하고, 슬라이딩을 양호하게 한 것이다.The sliding panel 21 supports the sliding panel 21 by providing rails 28a and 28b at predetermined intervals above and below the inner surface of the flap door panel 12 to support the upper and lower sides, and thus the sliding panel 21 is easily supported. It is good.

그리고 플랩 도어 패널(12)의 내측면에 슬라이딩 패널(21)을 슬라이딩할 수 있게 지지할 때 최상단 또는 최하단 중의 어느 하나의 부위에 슬라이딩 패널(21)을 설치하지 않아서 그 부위의 에어유통공(13)은 고정단면적을 형성하도록 함으로써 항상 최소한의 환기를 하도록 한 것이다.When the sliding panel 21 is slidably supported on the inner surface of the flap door panel 12, the air distribution hole 13 of the portion is not provided because the sliding panel 21 is not installed at one of the uppermost and lowermost portions. ) Creates a fixed cross-sectional area to ensure minimal ventilation at all times.

또한 상기 엔진 룸(R)에는 온도센서(30)를 설치하여 엔진 룸(R)의 온도를 검출하여서 그 출력신호를 제어기(31)에 입력하고, 상기 제어기(31)는 상기 솔레노이드 밸브(26)에 전류를 보내서 유체도관(25a)(25b)을 선택적으로 개폐 제어하도록 한 것이다.In addition, a temperature sensor 30 is installed in the engine room R to detect the temperature of the engine room R, and the output signal is input to the controller 31, and the controller 31 is the solenoid valve 26. The current is sent to the fluid conduits 25a and 25b to selectively open and close the control.

상기 온도센서(30)는 라디에이터에 설치하여 엔진냉각수의 온도를 검출함으로써 에어유통공(13)의 에어유통 단면적을 양호하게 제어(조절)할 수 있도록 하여 엔진을 항상 최적상태로 운전할 수 있게 하는 것이 바람직하다.The temperature sensor 30 is installed in a radiator to detect the temperature of the engine coolant so that the air flow cross-sectional area of the air distribution hole 13 can be controlled (adjusted) well so that the engine can always be operated in an optimal state. desirable.

이상과 같은 본 발명은 엔진 룸(R)에 설치한 온도센서(30)의 출력신호를 제어기(31)에 입력하여 솔레노이드 밸브(26)를 선택 제어함으로써 에어유통 가변수단 (20)을 플랩 도어 패널(12)에서 슬라이딩시키고, 상기 에어유통 가변수단(20)의 슬라이딩 패널(21)이 슬라이딩할 때 슬라이딩 패널(21)에 형성한 에어 제어 유통공이 에어유통공(13)을 개폐하여 그 단면적을 증감함으로써 에어유통공(13)을 흐르는 에어유통량을 증감하는 것이다.In the present invention as described above, the air flow variable means 20 is flap door panel by inputting the output signal of the temperature sensor 30 installed in the engine room R to the controller 31 to selectively control the solenoid valve 26. And the air control flow hole formed in the sliding panel 21 opens and closes the air distribution hole 13 when the sliding panel 21 of the air flow variable means 20 slides. As a result, the amount of air flowing through the air distribution hole 13 is increased or decreased.

상기 에어유통공(13)을 흐르는 에어유통량은 라디에이터를 흐르는 냉각수의 온도에 의하여 제어되는바, 예를 들어 엔진의 워밍업시에는 냉각수의 온도가 낮음으로 에어유통량을 작게 조절하고, 장거리를 고속으로 주행할 때에는 에어유통량을 많게 조절함으로써 라디에이터는 항상 쾌적한 상태로 냉각시킬 수 있는 것이다.The air flow rate flowing through the air distribution hole 13 is controlled by the temperature of the coolant flowing through the radiator. For example, when the engine warms up, the air flow rate is adjusted to be low due to the low temperature of the coolant, and the long distance is driven at high speed. The radiator can always be cooled in a comfortable state by adjusting the air flow volume.

상기와 같이 엔진 룸(R)의 환기시 에어유통공(13)을 흐르는 에어유통량이 감소되면 에어유통공(13)의 단면적도 감소되기 때문에 엔진에서 방사되는 소음의 대기배출도 감소되어 환경공해를 저감할 수 있고, 또한 엔진을 최적상태로 운전함으 로 즉 엔진의 과냉 및 과열을 방지함으로써 소음발생도 감소하고 연료를 절감할 수 있는 것이다.As described above, if the air flow volume flowing through the air distribution hole 13 is reduced during the ventilation of the engine room R, the cross-sectional area of the air distribution hole 13 is also reduced, thereby reducing the atmospheric emission of noise emitted from the engine, thereby reducing environmental pollution. In addition, by operating the engine in an optimal state, that is, by preventing overcooling and overheating of the engine, noise can be reduced and fuel can be saved.

이상과 같이 본 발명은 엔진 룸의 플랩 도어 패널에 일정단면적의 에어유통공을 형성하고, 상기 플랩 도어 패널의 내측면에 상기 에어유통공의 단면적을 제어하는 에어유통공 가변수단을 설치하여서, 냉각수의 온도에 의하여 상기 에어유통공의 단면적을 제어함으로써 에어유통공을 흐르는 에어유통량을 조절할 수 있기 때문에 소음의 외부배출을 감소하여 환경공해를 저감하고, 엔진을 항상 최적상태로 운전함으로써 소음발생도 감소하고 연료를 절감할 수 있는 것이다.As described above, the present invention forms an air distribution hole of a predetermined cross-sectional area in the flap door panel of the engine room, and installs an air distribution hole variable means for controlling the cross-sectional area of the air distribution hole in the inner surface of the flap door panel, thereby providing cooling water. By controlling the cross-sectional area of the air distribution hole according to the temperature of the air flow through the air distribution hole can be adjusted to reduce the external emissions of noise to reduce environmental pollution, the engine is always operating in the optimal state to reduce noise generation To save fuel.
