엔진냉각장치Engine cooling system

본 고안은 차량의 엔진을 냉각시키는 장치에 관한 것으로서, 더욱 구체적으로는 주행중인 차량의 엔진을 공기를 사용하여 냉각시켜 고속주행으로 인한 엔진의 과열방지 및 열효율을 증대시킬 수 있는 엔진냉각장치에 관한 것이다.The present invention relates to an apparatus for cooling an engine of a vehicle, and more particularly, to an engine cooling apparatus capable of increasing the thermal efficiency and preventing overheating of an engine due to high speed driving by cooling an engine of a driving vehicle using air. will be.

차량은 연료인 가솔린 또는 디젤유를 연소시켜서 발생되는 폭발에 의하여 회전력을 얻는 내연기관인 엔진을 사용하기 때문에 엔진이 매우 높은 고온의 상태를 갖는다. 따라서 엔진을 냉각시켜서 과열을 방지하고 엔진의 효율을 증대시키기 위하여 많은 노력이 경주되고 있으며 통상 엔진의 내부를 냉각수가 순환하도록 하여 엔진을 냉각시킨다.Since the vehicle uses an engine which is an internal combustion engine that obtains rotational force by an explosion caused by burning fuel gasoline or diesel oil, the engine has a very high temperature. Therefore, a lot of efforts have been made to cool the engine to prevent overheating and increase the efficiency of the engine, and the engine is cooled by allowing the coolant to circulate inside the engine.

그러나 냉각수를 이용하는 경우에는 비교적 높은 냉각효율을 얻을 수 있지만 구조가 복잡해지고 냉각수를 자주 보충하여야 하는 문제가 발생된다. 그리고 만족할만한 냉각효율을 얻는데 문제가 있었다.However, in the case of using the cooling water, a relatively high cooling efficiency can be obtained, but the structure becomes complicated and the problem of frequently replenishing the cooling water occurs. And there was a problem in obtaining satisfactory cooling efficiency.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본고안의 목적은 종래 냉각수를 사용하는 엔진의 냉각효율을 제고하기 위하여 냉각수와 병행하여 공기를 이용하여 냉각동작을 수행함으로서 고속주행시에도 엔진의 과열을 방지할 수 있는 엔진냉각장치를 제공하는데 있다.The present invention has been made to solve the above problems, the object of the present invention is to improve the cooling efficiency of the engine using a conventional cooling water in parallel with the cooling water to perform the cooling operation by using the air in the engine at high speed driving It is to provide an engine cooling device that can prevent overheating.

이하 첨부된 도면을 참고하여 본 고안의 엔진냉각장치를 상세히 설명하면 다음과 같다.Hereinafter, the engine cooling apparatus of the present invention will be described in detail with reference to the accompanying drawings.

본 고안의 공냉식냉각장치로서 엔진의 과열상태를 해소하기 위하여 엔진과 인접한 후드의 표면에 개폐될 수 있는 엔진냉각부재를 다수 설치한 것이다. 차량이 고속으로 주행하면 ECU에서 이것을 감지하고 외부의 환경이 비가 오고 있는가를 확인하여 엔진을 공냉시키도록 작동된다.The air-cooled cooling device of the present invention is to install a plurality of engine cooling member that can be opened and closed on the surface of the hood adjacent to the engine in order to solve the overheating state of the engine. When the vehicle is traveling at high speed, the ECU detects this and checks if the external environment is raining so that the engine is cooled by air.

도 1은 본 고안에 의한 엔진냉각장치의 미작동상태에서의 엔진냉각부재(2)의 설치상태를 도시한 것이다. 후드의 표면을 완전히 차단하고 있으므로 공기는 엔진이 위치한 기관실 내부로 유입되지 못하고 있는 상태이다. 상기 엔진냉각부재(2)는 약 3∼4개 정도를 설치하여 구성하는 것이 바람직하다.1 shows an installation state of the engine cooling member 2 in an inoperative state of the engine cooling apparatus according to the present invention. Since the surface of the hood is completely blocked, air is not allowed to enter the engine compartment where the engine is located. Preferably, the engine cooling member 2 is provided with about 3 to 4 or so.

엔진냉각부재(2)는 직사각형을 가진 다수의 분리된 부재로서 일측단부가 모두 연동되도록 고정부재(4)에 결합되어 있다. 상기 고정부재(4)는 전후이동이 가능한 것으로서 전후이동에 따라서 엔진냉각부재(2)들이 표면에 대하여 경사진 각도로 이동하게 되며 그 개방된 공간을 통하여 공기가 유입되는 것이다. 또한 고정부재(4)의 일부분에는 수평기어(6)가 형성되어 있다.Engine cooling member (2) is a plurality of separate members having a rectangle is coupled to the fixing member (4) so that one side end is all interlocked. The fixing member 4 is capable of front and rear movement, and the engine cooling members 2 move at an inclined angle with respect to the surface according to the front and rear movement, and air is introduced through the open space. In addition, a portion of the fixing member 4 is formed with a horizontal gear (6).

도 2는 본 고안에 의한 엔진냉각장치가 작동된 상태에서의 엔진냉각부재(2)의 상태를 도시한 것이다. 도시된 바와 같이 엔진냉각부재(2)가 표면에 밀착된 형태에서 표면에 대하여 일정한 각도로 경사진 형태로 이동된 것을 알 수 있다.Figure 2 shows the state of the engine cooling member (2) in the operating state of the engine cooling apparatus according to the present invention. As shown, it can be seen that the engine cooling member 2 is moved in a form inclined at a predetermined angle with respect to the surface in the form in close contact with the surface.

엔진냉각부재(2)를 이동시키는 수단을 설명한다. 고정부재(4)의 단부에는 수평기어(6)가 형성되어 있으며, 수평기어(6)에는 원형기어(8)가 결합된다. 상기 원형기어(8)는 구동모터(10)의 회전축에 연결되어 있어서 구동모터(10)가 동작되면 원형기어(8)가 회전하게 되고 이에 따라서 수평기어(6)가 전후이동을 하게 되는 것이다. 이러한 목적을 위하여 상기 구동모터(10)는 양방향회전이 가능한 모터를 사용하는 것이 바람직하다.Means for moving the engine cooling member 2 will be described. A horizontal gear 6 is formed at an end of the fixing member 4, and a circular gear 8 is coupled to the horizontal gear 6. The circular gear 8 is connected to the rotational shaft of the drive motor 10, so that when the drive motor 10 is operated, the circular gear 8 is rotated, so that the horizontal gear 6 is moved back and forth. For this purpose, the drive motor 10 preferably uses a motor capable of bidirectional rotation.

수평기어(6)가 전후이동하면 엔진냉각부재(2)의 일측단부는 고정부재(4)에 연동되어 있으므로 수평상태에서 도 2에서와 같이 경사진 상태로 이동하게 된다. 엔진냉각부재(2)의 타단부는 회전축역할을 하도록 고정되어 있다. 이렇게 엔진냉각부재(2)가 경사지도록 이동하게 되면 공간이 형성되고 그 공간을 통하여 공기가 유입된다. 유입된 공기는 엔진을 통과하면서 냉각시키게 된다. 따라서 엔진은 종래의 냉각수에 의한 냉각효과와 공기에 의한 냉각효과에 의하여 동시에 냉각되므로 냉각효과가 개선된다.When the horizontal gear 6 is moved back and forth, one side end of the engine cooling member 2 is interlocked with the fixing member 4, so that the horizontal gear 6 moves to the inclined state as shown in FIG. The other end of the engine cooling member 2 is fixed to serve as a rotating shaft. When the engine cooling member 2 moves to be inclined in this way, a space is formed and air is introduced through the space. The incoming air cools down as it passes through the engine. Therefore, since the engine is simultaneously cooled by the cooling effect by the conventional cooling water and the cooling effect by the air, the cooling effect is improved.

상기와 같이 엔진냉각부재(2)를 작동시키는 구동모터(10)는 다음과 같은 상황에서 동작된다. 도 3을 참고하면, 운전자가 가속페달(12)을 밟으면 이것을 ECU(20)에서 감지하고 차속센서(14)로 차량의 속도를 감지한다. 차량의 속도가 고속이면 다시 온도센서(16)로 엔진의 온도를 감지한다. 저속상태이면 본 고안의 장치의 작동은 중지된다.The driving motor 10 for operating the engine cooling member 2 as described above is operated in the following situation. Referring to FIG. 3, when the driver presses the accelerator pedal 12, the driver 20 detects this from the ECU 20 and detects the speed of the vehicle with the vehicle speed sensor 14. When the speed of the vehicle is high, the temperature of the engine is detected again by the temperature sensor 16. In the low speed state, the device of the present invention is stopped.

통상 고속주행상태에서는 엔진의 냉각수온도가 고온으로 상승하므로 온도가 소정온도이상을 초과하게 된다. 온도센서(16)로부터 측정된 온도가 소정온도이상이면 ECU(20)에서는 와이퍼스위치(18)의 온/오프상태를 감지한다. 이것은 현재 외기의 상태를 확인하기 위한 것으로서, 우천시에는 와이퍼를 작동시키므로 와이퍼스위치(18)가 온상태이면 비가 오는 것으로 판단하고 본 고안의 엔진냉각장치의 작동을 중지한다. 와이퍼스위치(18)가 오프상태이면 ECU(20)에서는 본 고안의 엔진냉각장치를 작동시키기 위하여 제어신호를 출력한다.In the high speed driving state, the coolant temperature of the engine rises to a high temperature so that the temperature exceeds a predetermined temperature. If the temperature measured by the temperature sensor 16 is greater than or equal to a predetermined temperature, the ECU 20 detects an on / off state of the wiper switch 18. This is to check the current state of the outside air, and in the rain, the wiper is operated, so if the wiper switch 18 is turned on, it is determined that it is raining and the operation of the engine cooling system of the present invention is stopped. If the wiper switch 18 is in the off state, the ECU 20 outputs a control signal to operate the engine cooling device of the present invention.

출력된 제어신호는 트랜지스터(22)에 의하여 충분한 크기의 신호로 증폭된 후에 릴레이(24)를 작동시킨다. 릴레이(24)에 의하여 구동모터(10)에 전원이 인가되면 구동모터(10)가 작동하여 도 2에서와 같이 고정부재(4)를 이동시키고 이에 따라서 엔진냉각부재(2)가 경사진 형태가 되어서 엔진이 공기에 의하여 냉각되는 효과가 있는 것이다.The output control signal is amplified into a signal of sufficient magnitude by the transistor 22 to operate the relay 24. When power is applied to the drive motor 10 by the relay 24, the drive motor 10 is operated to move the fixing member 4 as shown in FIG. 2, whereby the engine cooling member 2 is inclined. Thus, the engine is cooled by the air.

상기와 같이 본 고안에 의하면 종래 냉각수를 사용하는 엔진의 냉각효율을 제고하기 위하여 냉각수와 병행하여 공기를 이용하여 냉각동작을 수행함으로서 고속주행시에도 엔진의 과열을 방지할 수 있는 이점이 있는 것이다.As described above, according to the present invention, there is an advantage of preventing overheating of the engine even at high speed by performing a cooling operation using air in parallel with the cooling water in order to improve the cooling efficiency of the engine using the conventional cooling water.

본 고안은 기재된 구체예에 대해서만 설명되었지만 본 고안의 사상과 범위내에서 변경이나 변형할 수 있음은 본 고안이 속하는 분야의 당업자에게는 명백한 것이며 그러한 변경이나 변형은 첨부된 실용신안등록청구의범위에 의하여 제한되어져야 한다.Although the present invention has been described only with respect to the embodiments described, it will be apparent to those skilled in the art that the present invention may be changed or modified within the spirit and scope of the present invention, and such changes or modifications may be made by the appended claims of utility model registration. Should be limited.
