본 발명은 자동차의 엔진 냉각팬에 관한 것으로서 특히, 자동차의 엔진에 구비된 냉각팬의 날개형상을 변형하여 냉각팬 회전시 엔진의 냉각을 원활하게 하기 위한 장치로써, 운행 안전성을 향상시킬 수 있는 자동차의 엔진 냉각팬에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine cooling fan of an automobile, and in particular, an apparatus for smoothing the cooling of an engine when the cooling fan is rotated by modifying the wing shape of the cooling fan provided in the engine of the automobile. Relates to an engine cooling fan.
일반적으로 종래의 자동차의 엔진 냉각팬은 엔진에 구비된 냉각장치의 하나이며, 냉각장치는 작동 중인 엔진의 폭발시 발생되는 열을 냉각시켜 엔진의 온도를 알맞게 유지하는 장치이며 엔진을 냉각시키는 냉각수의 정상적인 온도는 75∼85℃ 정도이다.In general, the engine cooling fan of a conventional vehicle is one of the cooling devices provided in the engine, the cooling device is a device for maintaining the temperature of the engine by cooling the heat generated during the explosion of the engine in operation and the cooling water for cooling the engine Normal temperature is 75-85 degreeC.
폭발행정 중의 연소가스의 온도는 2000℃ 정도에 달하며, 이 열은 실린더 벽, 실린더 헤드, 피스톤, 밸브 및 기타의 엔진 부품으로 전도되는데 냉각장치는 이들 부품이 과열되지 않게 과잉의 열을 흡수하여 냉각시켜 주는 장치이다.The temperature of the combustion gases during the explosive stroke reaches 2000 ° C, and this heat is conducted to the cylinder walls, cylinder heads, pistons, valves and other engine parts. The chiller absorbs excess heat to cool these parts without overheating them. It is a device that allows.
엔진이 과열되었을 때, 엔진에 손상을 입히게 되며, 그 손상으로는 금속이 빨리 산화하고, 냉각수의 순환이 불량해지며, 각 작동부분의 소결 및 각 부품의 변형원인이 되고, 윤활 불충분으로 인하여 각 부품이 손상되며 조기점화 및 노킹이 발생하여 엔진의 출력이 저하된다.When the engine is overheated, it causes damage to the engine, which causes the metal to oxidize quickly, poor circulation of the cooling water, cause sintering of each working part and deformation of each part, and due to insufficient lubrication Damaged parts, premature ignition and knocking occur, resulting in lower engine power.
엔진 냉각팬은 상기와 같이 과열에 의하여 발생하는 엔진의 손상을 줄이기 위하여 일반적으로 냉각수의 온도가 85℃이사이 되었을 때 회전하도록 형성되어 있다.The engine cooling fan is generally configured to rotate when the temperature of the coolant reaches 85 ° C. in order to reduce damage to the engine caused by overheating as described above.
도 1은 종래의 자동차의 엔진 냉각팬을 구비한 엔진을 도시하는 도이다.1 is a diagram illustrating an engine having an engine cooling fan of a conventional vehicle.
도 1에 도시된 바와 같이, 종래의 자동차의 엔진 냉각팬은 일정각도로 형성된 다수개의 날개(110)를 구비하여 엔진(200)에 형성된 냉각팬(100)으로 구성된다.As shown in FIG. 1, the engine cooling fan of a conventional vehicle includes a cooling fan 100 formed in the engine 200 having a plurality of wings 110 formed at a predetermined angle.
이와 같이 구성된 종래의 자동차의 엔진 냉각팬은 엔진(200)을 냉각시키기 위하여 실린더블록의 내부를 순환하는 냉각수의 온도가 일반적으로 85℃이상이 되었을 때, 일정각도로 형성된 다수개의 날개(110)를 구비하여 엔진(200)에 형성된 냉각팬(100)이 회전하게 된다.The engine cooling fan of the conventional vehicle configured as described above has a plurality of blades 110 formed at a predetermined angle when the temperature of the coolant circulating inside the cylinder block is generally 85 ° C. or higher to cool the engine 200. The cooling fan 100 formed in the engine 200 is rotated.
상기 냉각팬(100)의 회전에 의하여 주변의 공기를 엔진(200) 주위로 송출하면, 송출된 공기가 엔진(200)에서 발생하는 열을 식히게 되며, 냉각효율을 높이기 위해서는 상기 냉각팬(100)에 구비된 날개(110)의 개수나 냉각팬(100)의 회전수를 증가시키고 있다.When the surrounding air is sent out around the engine 200 by the rotation of the cooling fan 100, the emitted air cools the heat generated by the engine 200, and in order to increase the cooling efficiency, the cooling fan 100 Increasing the number of the blades 110 and the rotation speed of the cooling fan (100).
그러나, 종래의 자동차의 엔진 냉각팬(100)의 냉각효율을 높이기 위하여 날개(110)의 개수나 냉각팬(100)의 회전수를 증가시키는 것은 기술상의 한계가 있기 때문에 일정효율 이상으로 냉각효율을 상승시킬 수 없다는 기술상의 문제점이 있었다.However, in order to increase the cooling efficiency of the engine cooling fan 100 of a conventional automobile, increasing the number of the blades 110 and the rotation speed of the cooling fan 100 has technical limitations. There was a technical problem that it could not be raised.
본 발명은 상기의 결점을 해소하기 위한 것으로, 자동차의 엔진에 구비된 냉각팬의 날개형상을 변형하여 냉각팬 회전시 엔진의 냉각을 원활하게 하여 운행 안전성을 향상시킬 수 있도록 하는 자동차의 엔진 냉각팬을 제공하고자 한다.The present invention is to solve the above-described drawbacks, the engine cooling fan of the vehicle to modify the blade shape of the cooling fan provided in the engine of the automobile to smooth the cooling of the engine when the cooling fan rotation to improve the driving safety To provide.
이러한 본 발명은 일정각도로 형성된 다수개의 날개를 구비하여 엔진에 형성된 냉각팬에 있어서; 상기 냉각팬에 형성된 날개의 중심선을 따라 날개면에 수직하게 에어댐이 추가 구성됨으로써 달성된다.The present invention comprises a cooling fan formed in the engine having a plurality of wings formed at a predetermined angle; The air dam is additionally configured perpendicularly to the wing surface along the center line of the wing formed in the cooling fan.

도 2는 본 발명의 자동차의 엔진 냉각팬을 도시하는 도이다.2 is a diagram illustrating an engine cooling fan of a motor vehicle of the present invention.
본 발명의 실시예를 첨부 도면을 참고하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2에 도시된 바와 같이 본 발명의 자동차의 엔진 냉각팬은 일정각도로 형성된 다수개의 날개(110)를 구비하여 엔진(200)에 형성된 냉각팬(100)에 있어서; 상기 냉각팬(100)에 형성된 날개(110)의 중심선을 따라 날개면에 수직하게 에어댐(120)이 추가 형성되는 것을 그 기술상의 특징으로 한다.As shown in FIG. 2, an engine cooling fan of an automobile of the present invention includes a cooling fan 100 formed in an engine 200 having a plurality of vanes 110 formed at a predetermined angle; According to the technical feature that the air dam 120 is further formed perpendicular to the wing surface along the centerline of the wing 110 formed in the cooling fan 100.
이하, 도 2를 참고하여 본 발명의 작용을 설명하면 다음과 같다.Hereinafter, referring to Figure 2 describes the operation of the present invention.
엔진(200)을 냉각시키기 위하여 실린더블록의 내부를 순환하는 냉각수의 온도가 일반적으로 85℃이상이 되었을 때, 일정각도로 형성된 다수개의 날개(110)를 구비하여 엔진(200)에 형성되어 에어댐(120)이 구비된 냉각팬(100)이 회전하게 된다.When the temperature of the coolant circulating inside the cylinder block to cool the engine 200 is generally 85 ° C. or more, a plurality of vanes 110 formed at a predetermined angle are formed in the engine 200 to form an air dam ( The cooling fan 100 provided with 120 is rotated.
상기 에어댐(120)을 구비한 냉각팬(100)의 회전에 의하여 주변의 공기를 엔진(200) 주위로 더욱 효과적으로 송출하게되며, 송출된 공기가 엔진(200)에서 발생하는 열을 식히기 된다.By rotating the cooling fan 100 having the air dam 120, the surrounding air is more effectively sent out around the engine 200, and the air is cooled to cool the heat generated by the engine 200.
따라서, 동일한 회전수와 동일한 날개(110) 개수로 형성된 상기 냉각팬(100)이 회전하게 되었을 때, 에어댐(120)이 형성되지 않은 것에 비하여 공기와의 접촉면적이 증가하여 많은 공기를 엔진(200)으로 송출하게 되어 냉각효율을 향상시키게 된다.Therefore, when the cooling fan 100 formed with the same rotational speed and the same number of blades 110 is rotated, the contact area with air increases as compared to the case where the air dam 120 is not formed. ) To improve cooling efficiency.
이상과 같은 본 발명은 자동차의 엔진에 구비된 냉각팬의 날개형상을 변형하여 냉각팬 회전시 엔진의 냉각을 원활하게 하여 운행 안전성을 향상시킬 수 있는 발명인 것이다.The present invention as described above is an invention that can improve the running safety by smoothly cooling the engine when the cooling fan rotates by modifying the wing shape of the cooling fan provided in the engine of the automobile.
