Description

차량용 라디에이터의 바람유입장치{Wind inflow device of an automotive radiator}Wind inflow device of an automotive radiator

본 발명은 차량용 라디에이터의 바람유입장치에 관한 것으로, 보다 상세하게는 차량의 주행 중 냉각팬의 회전을 강제로 멈추어 유입되는 바람을 통해 고온의 냉각수를 냉각할 수 있도록 된 차량용 라디에이터의 바람유입장치에 관한 것이다.The present invention relates to a wind inlet device for a radiator for a vehicle, and more particularly, to a wind inlet device for a radiator for a vehicle that can cool the high temperature cooling water through the wind flowing by forcibly stopping the rotation of the cooling fan during driving of the vehicle. It is about.

일반적으로 차량의 엔진은 그 내부에서 발생되는 폭발력에 의해 회전 동력을 얻는 것으로 이와 같은, 엔진내의 폭발에 의해 엔진은 항상 고온으로 가열되므로 물을 엔진내로 순환시켜 엔진을 냉각시키게 되며 통상, 이와 같은 수냉식 냉각시스템은 엔진의 회전력을 이용해 냉각수를 펌핑하는 펌프와 엔진으로부터 배출된 고온의 냉각수를 식히는 라디에이터 및 엔진과 라디에이터사이로 냉각수를 순환시키는 배관라인으로 이루어지게 된다.In general, the engine of a vehicle obtains rotational power by the explosive force generated therein. Since the engine is always heated to a high temperature by the explosion in the engine, water is circulated in the engine to cool the engine. The cooling system consists of a pump for pumping the coolant using the rotational force of the engine, a radiator for cooling the hot coolant discharged from the engine, and a piping line for circulating the coolant between the engine and the radiator.

여기서, 상기 라디에이터에는 엔진으로부터 배출되는 고온의 냉각수를 순환시키면서 외부로부터 빠른 속도로 바람을 유입시켜 신속하게 열을 빼앗도록 그 앞쪽으로 구비된 냉각팬을 제어하여 외부의 바람을 유입시키는 장치는 도 1에 도시된 바와 같이, 엔진의 크랭크샤프트에 유체클러치로 연결되어 있으며 엔진 내의 온도가 일정 이상으로 상승되면 크랭크샤프트에 직결되어 회전되는 구동모터(20)의 회전축(20a)을 매개로 회전되는 냉각팬(10)이 엔진에서 배출된 고온의 냉각수를 냉각시키는 라디에이터의 전방에 장착되어 외부로부터 빠른 속도로 바람을 유입시켜 냉각수의 방열 효과를 높이게 된다.Here, the radiator controls the cooling fan provided in front of the radiator to circulate the high-temperature cooling water discharged from the engine at a high speed so as to quickly take in heat from the outside, thereby introducing external wind. As shown in the figure, the cooling fan is connected to the crankshaft of the engine by a fluid clutch and is rotated through the rotation shaft 20a of the drive motor 20 which is directly connected to the crankshaft and rotated when the temperature in the engine rises above a certain level. 10 is mounted to the front of the radiator for cooling the high temperature cooling water discharged from the engine to increase the heat radiating effect of the cooling water by flowing wind at a high speed from the outside.

그러나, 이와 같이 엔진 온도가 높으면 크랭크샤프트와 자동으로 연결되는 반면 엔진의 온도가 높지 않으면 자동으로 떨어져 냉각팬(10)을 회전시키지 않게 되지만, 차량의 주행에 따라 유입되는 바람의 풍속이 워낙 빨라 라디에이터의 전방에 구비된 냉각팬(10)부위로 유입되어 통과되는 바람에 의해 저속으로 회전되는 현상이 발생되고 이로 인해, 냉각팬(10)에 의해 가려져 바람의 유입이 방해를 받는 라디에이터부위는 가려지지 않은 부위에 비해 냉각성능이 저하되는 단점이 있게 된다.However, if the engine temperature is high in this way, the crankshaft is automatically connected to it, but if the engine temperature is not high, the cooling fan 10 is not rotated automatically, but the wind speed of the inflow of the car is very fast. The phenomenon of rotation at a low speed is caused by the wind passing through the cooling fan 10 provided at the front of the cooling fan 10, and thus the radiator portion is blocked by the cooling fan 10, thereby preventing the inflow of wind. There is a disadvantage in that the cooling performance is reduced compared to the portion that is not.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 차량의 차속이 설정 값을 초과하면 유입되는 바람에 의한 냉각팬의 회전을 강제로 저지시켜 냉각팬에 의해 라디에이터로 유입되는 바람의 흐름을 방해하지 않도록 함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above, and when the vehicle speed of the vehicle exceeds the set value, the rotation of the cooling fan due to the inflow of wind is forcibly prevented, thereby preventing the flow of wind flowing into the radiator by the cooling fan. The purpose is not to disturb.

상기와 같은 목적을 달성하기 위한 본 발명은, 라디에이터의 전방에 장착되어 유체클러치를 매개로 크랭크샤프트에 연결되는 구동모터에 의해 회전되는 냉각팬과, 이 냉각팬의 자유 회전을 차속센서와 엔진온도의 신호를 받아 정지시키는 콘트롤러 및 이 콘트롤러의 신호에 따라 냉각팬이 연결된 구동모터의 회전축을 강제로 가압하여 정지시키는 멈춤수단으로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, the cooling fan is rotated by a drive motor mounted to the front of the radiator connected to the crankshaft through the fluid clutch, and the free rotation of the cooling fan to the vehicle speed sensor and engine temperature And a stop means for forcibly pressing and stopping the rotating shaft of the driving motor to which the cooling fan is connected according to the signal of the controller.

It consists of a stop means (50) for forcibly pressing the rotary shaft (20a) of the drive motor 20 is connected to the stop 10.

여기서, 상기 멈춤수단(50)은 도 3과 도 4에 도시된 바와 같이 서로 분리되어 구동모터(20)의 회전축(20a)에 상·하 부위에서 간격을 두고 감싸는 한 쌍의 어퍼·로워 스토퍼(51,51')와, 이 스토퍼(51,51')의 양단에 각각 돌출된 플랜지(53)에 장착되어 스토퍼(51,51')를 회전축(20a)으로 밀착·분리시키도록 콘트롤러(30)에 의해 제어되는 한 쌍의 솔레노이드(52,52')로 이루어진다.Here, the stop means 50 is separated from each other as shown in Figs. 3 and 4 is a pair of upper and lower stoppers wrapped at intervals in the upper and lower portions on the rotary shaft 20a of the drive motor 20 ( 51, 51 'and flanges 53 protruding from both ends of the stoppers 51, 51', respectively, so as to contact and separate the stoppers 51, 51 'with the rotation shaft 20a. It consists of a pair of solenoids 52, 52 'controlled by the.

이때, 상기 솔레노이드(52,52')는 콘트롤러(30)에 의해 온(On)될 때 스토퍼(51,51')의 플랜지(53)를 잡아당겨 회전축(20a)을 정지시키는 로드(52a,52')와, 콘트롤러(30)에 의해 오프(Off)될 때 스토퍼(51,51')의 플랜지(53)를 회전축(20a)에서 떨어지도록 복귀시키는 스프링(52b,52b')로 이루어진다.At this time, the solenoids 52 and 52 'pull the flanges 53 of the stoppers 51 and 51' when the solenoids 52 and 52 'are turned on to stop the rotation shaft 20a. ') And springs 52b and 52b which return the flanges 53 of the stoppers 51 and 51' away from the rotation shaft 20a when turned off by the controller 30.

이하 본 발명의 작동을 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail.

먼저, 엔진 내의 온도가 일정 이상으로 상승되면 전술한 종래의 경우와 같이 크랭크샤프트에 직결되어 회전되는 구동모터(20)의 회전축(20a)을 매개로 회전되는 냉각팬(10)이 엔진에서 배출된 고온의 냉각수를 냉각시키는 라디에이터 쪽으로 외부의 바람을 유입시켜 냉각수의 방열 효과를 높이게 된다.First, when the temperature in the engine rises above a certain level, the cooling fan 10 rotated through the rotation shaft 20a of the driving motor 20 which is directly connected to the crankshaft and rotated as in the conventional case described above is discharged from the engine. The outside air flows into the radiator that cools the high temperature coolant to increase the heat radiation effect of the coolant.

이때, 본 발명에 따른 콘트롤러(30)는 차속센서(40)로부터 지속적으로 차량의 차속을 측정하게 되지만 측정된 차속이 설정된 일정 값을 초과하지 않게 되면, 도 5에 도시된 바와 같이 멈춤수단(50)의 솔레노이드(52,52')에 전원을 통전시키지 않게 되므로 라디에이터는 냉각팬(10)에 의한 방열 효과를 지속하게 된다.At this time, the controller 30 according to the present invention continuously measures the vehicle speed of the vehicle from the vehicle speed sensor 40, but when the measured vehicle speed does not exceed a predetermined value, the stopping means 50 as shown in FIG. Since the electric power is not supplied to the solenoids 52 and 52 'of the radiator, the radiator continues the heat dissipation effect by the cooling fan 10.

한편, 차속센서(40)로부터 측정된 차속이 일정 값을 넘어서고 엔진의 온도도 저하되어 크랭크샤프트와 구동모터(20)를 연결한 유체클러치가 떨어지면 콘트롤러(30)가 배터리의 전원을 멈춤수단(50)의 솔레노이드(52,52')로 통전시켜 솔레노이드(52,52')를 온시키게 된다.On the other hand, if the vehicle speed measured from the vehicle speed sensor 40 exceeds a predetermined value and the temperature of the engine is also lowered and the fluid clutch connecting the crankshaft and the driving motor 20 drops, the controller 30 stops the power supply of the battery. The solenoids 52, 52 'are energized to turn on the solenoids 52, 52'.

이어, 상기 솔레노이드(52,52')가 온 되면 도 6에 도시된 바와 같이 솔레노이드(52,52')의 로드(52a,52')가 당겨지면서 이 로드(52a,52')에 결합된 스토퍼(51,51')의 플랜지(53)도 함께 이동되고 이에 따라, 상기 스토퍼(51,51')가 유입되는 바람에 의해 회전되는 냉각팬(10)과 함께 회전되는 회전축(20a)을 가압하여 정지시켜 냉각팬(10)의 회전을 강제로 멈추게 한다.Subsequently, when the solenoids 52 and 52 'are turned on, as shown in FIG. 6, the rods 52a and 52' of the solenoids 52 and 52 'are pulled and the stoppers coupled to the rods 52a and 52'. The flanges 53 of the 51 and 51 'are also moved together, thereby pressing the rotating shaft 20a which is rotated together with the cooling fan 10 which is rotated by the wind in which the stoppers 51 and 51' are introduced. By stopping, the rotation of the cooling fan 10 is forcibly stopped.

이때, 상기 콘트롤러(30)는 차속과 엔진의 온도를 모니터링하여 이와 같이 멈춤수단(50)이 작동된 후 만약, 엔진의 온도가 다시 상승하여 구동모터(20)와 크랭크샤프트가 유체클러치로 연결되었지만 차속이 일정 값 이상으로 유지되면 라디에이터의 빠른 방열효과를 위해 멈춤수단(50)을 오프시키게 된다.At this time, the controller 30 monitors the vehicle speed and the temperature of the engine, and thus, the stop means 50 is operated. If the temperature of the engine rises again, the drive motor 20 and the crankshaft are connected to the fluid clutch. When the vehicle speed is maintained above a predetermined value, the stop means 50 is turned off for the rapid heat radiating effect of the radiator.

한편, 엔진의 온도가 그리 높지 않고 차속이 일정 값 이하로 저하되면 상기 콘트롤러(30)가 멈춤수단(50)으로 통전되는 전원을 오프하여 솔레노이드(52,52')를오프시키면 압축되었던 스프링(52b,52b)이 복원되면서 스토퍼(51,51')를 회전축(20a)으로부터 분리시켜 주게 됨은 물론이다.On the other hand, when the temperature of the engine is not so high and the vehicle speed falls below a certain value, the controller 30 turns off the power supplied to the stop means 50 to turn off the solenoids 52 and 52 ', thereby compressing the spring 52b. Of course, the stopper 51, 51 ′ is separated from the rotation shaft 20a while 52b is restored.

이상 설명한 바와 같이 본 발명에 의하면, 차량의 주행에 따라 유입되는 바람에 의해 회전되는 냉각팬을 차량의 차속 설정 값에 따라 작동되는 솔레노이드를 통해 회전을 강제로 정지시켜 라디에이터의 전방으로 위치된 냉각팬에 의해 유입되는 바람의 흐름이 방해받지 않게 되므로 라디에이터의 방열 성능이 증가되는 효과가 있게 된다.As described above, according to the present invention, a cooling fan that is rotated by the wind flowing in accordance with the driving of the vehicle is forced to stop the rotation through the solenoid operated according to the vehicle speed setting value of the cooling fan located in front of the radiator Since the flow of wind is not interrupted by the radiator has the effect of increasing the heat radiation performance of the radiator.
