Description

차량용 냉각 팬{COOLING FAN FOR VEHICLE}Automotive Cooling Fans {COOLING FAN FOR VEHICLE}

본 발명은 차량용 냉각 팬에 관한 것으로서, 보다 상세하게는 회전 날개의 외부 표면을 변형시킴으로써 회전 날개의 회전시 공기의 접촉 마찰 계수를 높여 풍량을 증대시킬 수 있도록 하는 차량용 냉각 팬에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle cooling fan, and more particularly, to a vehicle cooling fan that increases the amount of air by increasing a contact friction coefficient of air during rotation of a rotary blade by modifying an outer surface of the rotary blade.

일반적으로 차량의 엔진이 과열되면, 예를 들어 부품의 변형, 윤활유의 피막 파괴, 기관의 출력 저하 등의 현상이 유발된다. 따라서 엔진 가동시 혼합기의 연소에 의하여 발생되는 열의 일부를 냉각시켜 엔진의 과열을 방지하여 운전을 원활하게 할 수 있는 냉각 장치가 필요하다. 이러한 냉각 장치의 냉각 방식은 크게 공랭식과 수냉식으로 구분될 수 있다. 특히 공랭식은 기관을 직접 대기와 접촉시켜 열을 방산시키는 방식으로, 이는 자연 통풍식과 강제 통풍식으로 나뉘어진다. 자연 통풍식은 주행할 때 받는 공기만으로 냉각하는 방식인데, 예를 들어 실린더 블록이나 실린더 헤드와 같이 과열되기 쉬운 부분에 냉각 핀(Fin)을 돌출케 하여 방열 면적을 넓히는 것이다. 한편 강제 통풍식은 냉각 팬(Fan)을 이용하여 강제로 유입되는 다량의 공기로 냉각시키는 방식으로서, 엔진 주위에 냉각 팬을 감싸고 있는 시라우드를 설치하고 이곳을 통하여 냉각 공기를 다량 유입되게 한다. 이 냉각 팬은 주로 물 펌프 축과 일체로 회전하며 라디에이터를 통해 공기를 흡입하여 라디에이터의 통풍을 보조한다.In general, when the engine of a vehicle is overheated, a phenomenon such as deformation of a part, breakdown of a film of lubricating oil, and a decrease in engine power is caused. Therefore, there is a need for a cooling device capable of smoothly operating by preventing overheating of the engine by cooling part of the heat generated by combustion of the mixer during engine operation. The cooling method of such a cooling device can be largely divided into air cooling and water cooling. Air-cooling, in particular, dissipates heat by directly contacting the engine with the atmosphere, which is divided into natural and forced ventilation. Natural ventilation is a method of cooling only by the air received when driving, for example, to extend the heat dissipation area by protruding the cooling fin (Fin) to the portion that is easy to overheat, such as cylinder block or cylinder head. On the other hand, forced ventilation is a method of cooling with a large amount of air forcedly introduced by using a cooling fan (Fan), by installing a shroud surrounding the cooling fan around the engine to allow a large amount of cooling air flows through it. The cooling fan mainly rotates integrally with the water pump shaft and draws air through the radiator to assist the radiator ventilation.

도 1 은 종래의 차량용 냉각 팬의 형상을 나타낸 정면도이다.1 is a front view showing the shape of a conventional vehicle cooling fan.

도 1 에서, 종래의 냉각 팬(1)은 회전 축(2)의 둘레에 대략 4 ~ 8 정도의 회전 날개(3)가 방사상으로 형성되어 있다. 이러한 회전 날개(3)는 외부의 공기를 최적으로 흡입 또는 방출시키기 위하여 비틀린 상태의 형상을 갖추고 있다.In Fig. 1, the conventional cooling fan 1 is formed radially with the rotary vanes 3 of about 4 to about 8 around the rotation shaft 2. This rotary vane 3 has a shape of a twisted state in order to optimally suck or discharge the outside air.

이와 같이 구비된 종래의 냉각 팬(1)은, 예를 들어 도시되지 않은 물 펌프 축에 회전 축(2)이 결합되어 엔진의 작동에 따라 회전 날개(3)를 회전시키게 된다. 상기 회전 날개(3)의 회전에 따라 외부의 공기를 흡입 또는 방출시켜 냉각 작용을 하게 된다. 물론 수온 센서 등의 온도 감지에 의하여 전기적으로 작동되는 전동 팬인 경우에도 회전 날개(3)는 효율적인 공기 유로를 형성시키기 위하여 비틀린 형상을 이루고 있다.In the conventional cooling fan 1 provided as described above, the rotation shaft 2 is coupled to, for example, a water pump shaft (not shown) to rotate the rotary vanes 3 according to the operation of the engine. In accordance with the rotation of the rotary vane 3, the outside air is sucked or discharged to perform a cooling action. Of course, even in the case of an electric fan electrically operated by temperature sensing such as a water temperature sensor, the rotary vanes 3 form a twisted shape to form an efficient air flow path.

그러나, 종래의 냉각 팬(1)의 회전 날개(3)는 그 표면이 매끄러우므로 외부공기의 흡입 또는 방출시 공기의 접촉 마찰력이 저하된다. 이렇게 되면 흡입 또는 방출되는 공기가 회전 날개(3) 부분에 충분히 머물지 못하게 되므로 유통 공기량이 적어지게 되어 충분한 풍량을 얻을 수 없는 문제점이 있다.However, since the surface of the rotary vane 3 of the conventional cooling fan 1 is smooth, the contact frictional force of the air is reduced during the intake or discharge of the outside air. In this case, since the intake or discharge of the air is not enough to stay in the rotary blade (3) portion there is a problem that the amount of circulation air is reduced to obtain a sufficient amount of air.

따라서, 본 발명은 상술한 문제점을 해결하기 위하여 창작된 것으로서, 본 발명의 목적은 회전 운동에 따른 외부 공기의 흡입이나 방출시 회전 날개 부분에 공기의 마찰력을 더욱 증대시켜 충분한 풍량을 얻을 수 있도록 하는 차량용 냉각 팬을 제공하는 데 있다.Accordingly, the present invention has been made to solve the above-described problems, an object of the present invention is to increase the frictional force of the air to the rotary blade portion during the intake or discharge of the outside air according to the rotational movement to obtain a sufficient air volume An automotive cooling fan is provided.

이와 같은 목적을 달성하기 위한 본 발명에 따른 차량용 냉각 팬은, 회전 축 둘레에 방사상으로 비틀어진 형태의 복수의 회전 날개를 구비한 차량용 냉각 팬에 있어서, 상기 회전 날개의 각 끝단부는 흡입 또는 방출되는 외부 공기와의 마찰력을 높일 수 있도록 요철부를 더 포함하는 것을 특징으로 한다.A vehicle cooling fan according to the present invention for achieving the above object, in the vehicle cooling fan having a plurality of rotary blades of the radially twisted shape around the rotation axis, each end of the rotary blade is sucked or discharged Characterized in that it further comprises an uneven portion to increase the friction force with the outside air.

이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의하여 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

도 2 은 본 발명에 따른 차량용 냉각 팬의 형상을 나타낸 정면도이다.2 is a front view showing the shape of a vehicle cooling fan according to the present invention.

상기 도면에서, 본 실시예의 냉각 팬(10)은 회전 축(12)의 둘레에 대략 4 ~ 8 정도의 회전 날개(13)가 방사상으로 형성되어 있다. 이러한 회전 날개(13)는 주로 강판이나 합성 수지재로 이루어지고, 그 형상은 비틀린 형태를 이루고 있다. 이는 냉각 팬(10)의 고속 또는 저속 회전시 공기를 흡입 또는 방출시킬 수 있는 유로를 형성하기 위한 것이다.In the figure, the cooling fan 10 of this embodiment is formed with a radial blade 13 of about 4 to about 8 around the rotation axis 12. This rotary blade 13 mainly consists of a steel plate or a synthetic resin material, and the shape is the twisted form. This is for forming a flow path capable of sucking or releasing air during the high speed or low speed rotation of the cooling fan 10.

특히, 본 실시예에 따른 냉각 팬(10)의 회전 날개(13)는 그 각 단부의 표면 일부분에 공기의 마찰 계수를 높일 수 있도록, 예를 들어 엠보싱(Embossing) 가공 등에 의하여 요철부(13a)를 이루게 하고 있다. 물론, 이 요철부(13a)는 회전 날개(13)의 최초 성형 단계에서 일체로 성형하여도 좋고, 기존의 매끄러운 표면을 가진 회전 날개 위에 요철 형상을 가진 별도의 부재를 더 부착시켜도 무방하다.In particular, the rotary vanes 13 of the cooling fan 10 according to the present embodiment have a concave-convex portion 13a by embossing or the like so as to increase the coefficient of friction of air at a portion of the surface of each end thereof. To achieve. Of course, this uneven portion 13a may be integrally molded in the initial forming step of the rotary vane 13, or a separate member having an uneven shape may be further attached on the existing rotary vane having a smooth surface.

이와 같이 구비된 본 발명에 따른 차량용 냉각 팬(10)은, 도 3 에서 나타낸 바와 같이, 회전 날개(13)가 회전함에 따라 외부의 공기가 흡입 또는 방출할 때 다량의 공기와 요출부(13a)가 화살표 방향과 같이 서로 접촉된다. 이 때, 상기 요철부(13a) 쪽에 부딪히는 공기의 마찰력은 종래와 같이 매끄러운 표면에 부딪히는 공기의 마찰력에 비하여 상당히 높아진다. 이에 따라 이 요철부(13a) 부근에서 공기가 머무르는 시간이 상당히 길어지게 되므로 흡입 또는 방출되는 공기의 양이 커지게 되어 동일한 회전수(r.p.m) 영역에서 효과적으로 풍량을 증대시킬 수 있는 것이다.As illustrated in FIG. 3, the vehicle cooling fan 10 according to the present invention includes a large amount of air and a convex portion 13a when external air is sucked or discharged as the rotary vanes 13 rotate. Are in contact with each other as in the direction of the arrow. At this time, the frictional force of the air that hits the uneven portion 13a is considerably higher than the frictional force of the air that hits the smooth surface as in the prior art. As a result, the time for which the air stays in the vicinity of the uneven portion 13a becomes considerably longer, so that the amount of air sucked in or discharged is increased, so that the air volume can be effectively increased in the same rotational speed (r.p.m) region.

상술한 본 발명에 의하면, 냉각 팬의 회전 날개 끝단부 쪽에 부딪히는 공기의 마찰력을 더 높일 수 있게 되므로 접촉 공기의 체류 시간이 증대됨으로 인하여 풍량을 더욱 더 증대시킬 수 있다.According to the present invention described above, it is possible to further increase the frictional force of the air that hits the rotary blade end side of the cooling fan can further increase the amount of air due to the increase in the residence time of the contact air.
