Description

자동차용 냉각팬{a cooling fan of vehicles}Cooling Fan for Vehicles {a cooling fan of vehicles}

본 발명은 자동차용 냉각팬에 관한 것으로, 특히 라디에이터 셔터기능을 겸할 수 있도록 된 자동차용 냉각팬에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile cooling fan, and more particularly, to an automobile cooling fan that can serve as a radiator shutter function.

일반적으로 냉각팬이라 함은 라디에이터의 후면에 장치된 냉각용의 보조장치이며, 운전중에 다량의 공기를 빨아들임으로써 냉각작용을 더욱 효과적으로 하기 위한 것이다.In general, the cooling fan is an auxiliary device for cooling installed on the rear of the radiator, and is intended to more effectively cool down by sucking a large amount of air during operation.

전동모터에 의해 회전되는 소형차량의 냉각팬과는 달리 대형차량에서는 크랭크축에 연결된 벨트에 의해 냉각팬이 구동되며, 도 4에 도시된 바와 같이 환형 몸체(11)의 외측에 다수의 블레이드(12)가 형성되어 있고, 내부에는 클러치(13)가 장착된 구조로 이루어져 있다.Unlike the cooling fan of a small vehicle rotated by an electric motor, in a large vehicle, the cooling fan is driven by a belt connected to the crankshaft, and as shown in FIG. 4, a plurality of blades 12 are disposed outside the annular body 11. ) Is formed and has a structure in which the clutch 13 is mounted.

따라서, 일정온도가 되면 바이메탈에 의해 상기 클러치(13)가 고정되어 냉각팬을 회전시킴으로써 공기를 빨아들여 냉각작용을 행하도록 되어 있다.Therefore, when the temperature reaches a constant temperature, the clutch 13 is fixed by bimetal to suck the air to perform the cooling operation by rotating the cooling fan.

한편, 엔진은 적정온도 이상으로 가열되어야 효율적으로 출력을 발생하면서 가동되는데, 보통 냉각수의 온도가 75∼90℃가 되는 영역에서 엔진이 원활하게 작동된다.On the other hand, the engine must be heated above the proper temperature to efficiently operate while generating an output, the engine is normally operated smoothly in the region where the temperature of the cooling water is 75 ~ 90 ℃.

그런데 한랭지 또는 동절기에는 냉각수의 온도가 적정온도로 상승할 때 까지 시간이 오래 걸리며, 주행시의 주행풍으로 인해 이러한 현상은 더욱 심화되므로 별도의 라디에이터 셔터를 장착하여 과냉을 방지함으로써 냉각수의 온도가 적정온도로 빨리 가열되도록 하고 있다.However, in the cold or winter, it takes a long time until the temperature of the coolant rises to an appropriate temperature, and this phenomenon is exacerbated by the running wind during driving.Therefore, a separate radiator shutter is installed to prevent overcooling, so that the coolant temperature is appropriate. To heat up quickly.

따라서, 별도의 라디에이터 셔터를 장착하여야 하므로 비용이 추가되고, 설치공간의 확보를 차량 엔진룸의 레이아웃 구성시 염두에 두어야만 하는 불편함이 있었다.Therefore, additional radiator shutters have to be installed, which adds cost and has an inconvenience of keeping the installation space in mind when configuring the layout of the vehicle engine room.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 냉각팬이 라디에이터 셔터의 기능을 겸할 수 있게 됨으로써 별도의 라디에이터 셔터 추가설치가 필요 없도록 된 자동차용 냉각팬을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, and the object of the present invention is to provide a cooling fan for a vehicle in which a cooling fan can serve as a function of a radiator shutter so that a separate installation of a radiator shutter is not required.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1은 본 발명에 따른 냉각팬의 사시도로서, 본 발명은 냉각팬 중심의 환형 몸체(1)와 이 몸체(1)의 외주면에 방사상으로 일정간격을 두고 배열되는 다수의 블레이드(2)들이 별물로 제작되어, 블레이드(2)가 장착상태에서 부분적으로 회전할 수 있도록 되어 있다.1 is a perspective view of a cooling fan according to the present invention, the present invention is an annular body (1) in the center of the cooling fan and a plurality of blades (2) arranged radially at regular intervals on the outer peripheral surface of the body (1) is separate The blade 2 is rotatable partially in a mounted state.

상기 블레이드(2)에는 도 2에 도시된 바와 같이 밑면에 3개의 원형 핀들이 형성되는데, 중앙에는 몸체(1)에 회동가능한 상태로 블레이드(2)를 체결시키는 고정핀(3a)이 형성되며, 앞쪽에는 작동력을 인가받아 블레이드(2)를 회동시키는 연결핀(3b)이 형성되고, 뒤쪽에는 블레이드(2)의 회동이 안정적으로 이루어질 수 있도록 하는 안내핀(3c)이 형성되며, 이 안내핀(3c)과 상기 고정핀(3a)은 그 길이가 같고 연결핀(3b)은 안내핀(3c)과 고정핀(3a)에 비하여 이동부재(5 ; 이후 설명함)의 두께만큼 더 길게 형성되어 있고, 고정핀(3a)과 연결핀(3b)의 단부에는 나사산이 형성되어 너트(4a,4b)가 체결될 수 있도록 되어 있다.As shown in FIG. 2, three circular pins are formed at the bottom of the blade 2, and a fixing pin 3a is formed at the center to fasten the blade 2 in a rotatable state to the body 1. A connecting pin 3b for rotating the blade 2 is formed at the front by applying the operating force, and a guide pin 3c is formed at the rear to stably rotate the blade 2. 3c and the fixing pin (3a) is the same length and the connecting pin (3b) is formed longer than the thickness of the moving member (5; will be described later) than the guide pin (3c) and fixing pin (3a) At the ends of the fixing pin 3a and the connecting pin 3b, threads are formed so that the nuts 4a and 4b can be fastened.

한편, 도 3에 도시된 바와 같이 몸체(1)에는 블레이드(2)의 고정핀(3a)이 삽입되는 원형구멍(3a)들이 형성되고, 이 원형구멍(3a)을 중심으로 하는 동심원상에 상기 연결핀(3b)과 안내핀(3c)이 끼워지는 호형구멍(1b,1c)이 형성되되, 두 호형구멍(1b,1c)는 서로 반대방향으로 형성되어 있다.Meanwhile, as shown in FIG. 3, the body 1 has circular holes 3a into which the fixing pins 3a of the blades 2 are inserted, and the circular holes 3a are formed on the concentric circles around the circular holes 3a. Arc-shaped holes 1b and 1c into which the connecting pin 3b and the guide pin 3c are fitted are formed, and the two arc-shaped holes 1b and 1c are formed in opposite directions.

따라서, 핀(3a,3b,3c)들이 몸체(1)의 해당 구멍(1a,1b,1c)에 끼워진후 고정핀(3a)에 너트(4a)가 체결되고, 연결핀(3b)에는 몸체(1)의 안쪽에 구비되는 환형의 이동부재(5)를 관통한 뒤 너트(4b)가 체결되며, 안내핀(3c)는 단순히 호형구멍(1c)에 삽입된 상태로 블레이드(2)가 몸체(1)에 장착된다.Therefore, after the pins 3a, 3b and 3c are fitted into the corresponding holes 1a, 1b and 1c of the body 1, the nut 4a is fastened to the fixing pin 3a, and the body 3 is connected to the connecting pin 3b. The nut 4b is fastened after passing through the annular movable member 5 provided inside 1), and the guide pin 3c is simply inserted into the arc-shaped hole 1c so that the blade 2 is inserted into the body (1). 1) is mounted on.

그리고, 상기 몸체(1)의 안쪽면에는 3∼4곳에 왁스충진실린더(6)가 설치되고, 이 왁스충진실린더(6)의 실린더로드(6a)는 상기 이동부재(5)에 힌지연결되는 구조로 되어 있다.In addition, a wax filling cylinder 6 is installed at three to four places on an inner surface of the body 1, and the cylinder rod 6a of the wax filling cylinder 6 is hinged to the moving member 5. It is.

이제, 본 발명의 작동을 설명하기로 한다.The operation of the present invention will now be described.

상기 왁스충진실린더(6)의 내부에 들어 있는 왁스는 온도가 올라가면 팽창되면서 실린더로드(6a)를 밀고 온도가 내려가면 수축되어 실린더로드(6a)를 끌어 당기므로 평상시에는 실린더로드(6a)가 왁스충진실린더(6)의 내부에 인입된 상태로 있게 되며, 따라서 실린더로드(6a)에 연결된 이동부재(5)는 몸체(1)의 중간에 위치되므로 연결핀(3b)을 매개로 이동부재(5)에 연결되어 있는 블레이드(2)는 냉각팬의 축방향에 거의 수직한 상태에 위치되며, 이때 각 블레이드(2)들의 앞 뒤 단부가 서로 겹쳐진 상태가 되어 전체적으로 하나의 원판형상을 갖게 된다.The wax contained in the wax filling cylinder 6 expands when the temperature rises and pushes the cylinder rod 6a and contracts when the temperature decreases, thereby pulling the cylinder rod 6a. Since the moving member 5 connected to the inside of the filling cylinder 6 is located in the middle of the body 1, the moving member 5 connected to the cylinder rod 6a is moved through the connecting pin 3b. The blades 2 connected to the blades 2 are positioned substantially perpendicular to the axial direction of the cooling fan. At this time, the front and rear ends of the respective blades 2 are overlapped with each other to have one disc shape as a whole.

이와 같이 블레이드(2)들이 서로 겹쳐져 원판형상으로 되었을 때 냉각팬이 라디에이터 셔터의 기능을 하게 된다.As such, when the blades 2 overlap each other to form a disk, the cooling fan functions as a radiator shutter.

이후, 엔진가동으로 열이 발생되면, 복사에 의해 상기 왁스충진실린더(6)에 열이 전해져 내부의 왁스가 팽창되므로 실린더로드(6a)가 밀려 나오면서 이동부재(5)를 밀고, 이에 의해 블레이드(2)가 회전되어 경사진 상태로 됨으로써 공기를 빨아 들일 수 있게 되어 냉각팬 원래의 기능을 수행하게 된다.Then, when heat is generated by engine operation, heat is transmitted to the wax filling cylinder 6 by radiation, and the wax therein is expanded so that the cylinder rod 6a is pushed out, pushing the movable member 5, thereby pushing the blade ( 2) is rotated to be inclined state can suck the air to perform the original function of the cooling fan.

이때 상기 고정핀(1)은 블레이드(2) 회전의 중심이 되고, 연결핀(3b)은 이동부재(5)의 이동력을 블레이드(2)에 전달하는 매개체가 되며, 또한 안내핀(3c)은 연결핀(3b)과 같이 호형구멍(1b,1c)에 삽입되어 있어서 블레이드(2)의 회전동작이 안정적으로 이루어지는 것을 보조한다.At this time, the fixing pin (1) is the center of the blade (2) rotation, the connecting pin (3b) is a medium for transmitting the moving force of the moving member (5) to the blade (2), and also the guide pin (3c) Silver is inserted in the arc-shaped holes (1b, 1c) like the connecting pin (3b) to assist in the stable rotation of the blade (2).

따라서, 냉각팬이 공기를 빨아들이는 기능을 수행할 뿐만 아니라, 엔진이 적정온도까지 가열되기 전까지는 라디에이터 셔터의 역할을 할 수 있게 됨으로써 별도의 라디에이터 셔터의 장착이 필요 없게 된다.Therefore, the cooling fan not only sucks air, but also acts as a radiator shutter until the engine is heated to an appropriate temperature, thereby eliminating the need for a separate radiator shutter.

이상 설명한 바와 같이 본 발명에 따르면, 냉각팬의 블레이드가 온도조건에 따라 회동가능하게 됨으로써 엔진이 적정온도로 가열되기 전에는 블레이드들이 평면을 이루어 라디에이터 셔터의 기능을 하여 엔진이 보다 빨리 적정온도로 가열되어 작동될 수 있고, 엔진이 적정온도에 이른 후에는 블레이드가 경사진 상태로 회전되어 공기를 빨아 들임으로써 정상적인 냉각작용을 할 수 있게 되므로, 별도의 라디에이터 장착이 필요없어 비용이 절감되며, 엔진룸 레이아웃 구성시 라디에이터 설치공간 확보를 위한 고려를 하지 않아도 되는 장점이 있다.As described above, according to the present invention, the blades of the cooling fan can be rotated according to the temperature conditions, and before the engine is heated to an appropriate temperature, the blades form a plane to function as a radiator shutter so that the engine is heated to an appropriate temperature more quickly. After the engine reaches the proper temperature, the blade rotates in an inclined state and sucks air so that normal cooling can be performed, thus eliminating the need for a separate radiator, thereby reducing the cost and engine room layout. There is an advantage that does not need to consider for securing the radiator installation space when configuring.
