Description

차량 엔진룸 공기저항안정화장치{Airflux resistance stability apparatus for engine room in vehicle} Airflux resistance stability apparatus for engine room in vehicle}

본 발명은 차량 엔진룸에 관한 것으로, 특히 엔진룸으로 유입되는 주행풍에 의한 쿨링드래그(Cooling Drag)를 낮추는 공기저항안정화장치를 갖춘 엔진룸에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle engine room, and more particularly, to an engine room having an air resistance stabilization device for lowering a cooling drag due to running wind flowing into the engine room.

일반적으로 주행시 주행풍은 엔진룸을 지나면서 쿨링드래그(Cooling Drag)를 발생시킨다.In general, when driving, the driving wind passes through the engine room and generates a cooling drag.

상기와 같은 쿨링드래그(Cooling Drag)는 냉각계를 구성하는 라디에이터를 포함한 냉각용 쿨링모듈(Cooling Module)을 기준으로 할때, 크게 2가지 저항성분으로 분류할 수 있다.The cooling drag as described above can be largely classified into two resistance components based on a cooling module for cooling including a radiator constituting a cooling system.

즉, 쿨링드래그(Cooling Drag)는 크게 공기 입구부와 쿨링모듈 사이에 작용하는 저항인 인터날저항(Internal Drag)과, 쿨링모듈 이후 엔진룸 및 하체에 걸리는 저항인 인터퍼런스저항(Interference Drag)의 합으로 형성된다.In other words, the cooling drag has an internal drag, which is a resistance acting between the air inlet and the cooling module, and an interference drag, which is a resistance applied to the engine room and the lower body after the cooling module. It is formed by the sum of.

이는, CDC(Cooling Drag Coefficient) = CDC,ITD + CDC,IFD 관계를 갖는다.This has a relationship of Cooling Drag Coefficient (CDC) = CDC, ITD + CDC, IDF.

CDC,ITD : Cooling Drag Coefficient, Internal Drag, CDC,IFD : Cooling Drag Coefficient, Interference Drag CDC, ITD: Cooling Drag Coefficient, Internal Drag, CDC, IFD: Cooling Drag Coefficient, Interference Drag

상기와 같은 쿨링드래그(Cooling Drag)는 개구면적과 쿨링모듈, 엔진룸 레이아웃 및 전면부 형상에 영향을 받으며, 그 값이 클수록 연비를 저하시키고 엔진후드의 흔들림을 증가시킨다.The cooling drag as described above is affected by the opening area, the cooling module, the engine room layout, and the shape of the front part, and the larger the value, the lower the fuel economy and the shaking of the engine hood.

쿨링드래그(Cooling Drag)로 인한 연비저하는 인증연비대비 실도로연비 차이로 나타나며, 쿨링드래그(Cooling Drag)로 인한 엔진후드 흔들림은 고속주행시 주로 발생된다.The reduction in fuel consumption due to cooling drag results in a difference in fuel efficiency compared to certified fuel efficiency, and the shaking of the engine hood due to cooling drag occurs mainly at high speeds.

고속주행시 엔진룸내에는 고압영역이 분포되고, 이는 엔진룸 유동소기성불량을 가져오며, 엔진룸레이아웃의 영향이 부가되어 쿨링모듈 이후 저항인 인터퍼런스저항(Interference Drag)을 크게하여 쿨링드래그(Cooling Drag)를 악화시킴으로써, 엔진후드의 상하떨림을 악화시키게 된다.At high speeds, the high pressure area is distributed in the engine room, which results in a lack of fluidity in the engine room, and the effect of the engine room layout is added to increase the interference drag, which is a resistance after the cooling module. By worsening the cooling drag, the top and bottom vibration of the engine hood is worsened.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 저속주행시 주행풍을 엔진전단으로 유도해 쿨링드래그(Cooling Drag)를 낮추고, 고속주행시 주행풍을 엔진전단쪽 분기흐름과 엔진쪽으로 동시에 흐름을 유도해 쿨링모듈이후 저항인 인터퍼런스저항(Interference Drag)을 줄여줌으로써, 인증연비와 실도로연비를 일치시키고, 쿨링드래그(Cooling Drag)로 인한 엔진후드 흔들림도 줄이는 차량 엔진룸 공기저항안정화장치를 제공함에 목적이 있다.Accordingly, the present invention has been invented in view of the above, and induces driving wind to the engine front during low speed driving, thereby lowering the cooling drag, and simultaneously flows the driving wind to the engine front branch flow and the engine at high speed driving. By reducing the interference drag, which is the resistance after the cooling module, by matching the fuel efficiency with the actual fuel efficiency, the vehicle engine room air resistance stabilizer that reduces the engine hood shaking due to the cooling drag The purpose is to provide.

또한, 본 발명은 엔진룸하부에서 에어댐을 형성함으로써, 차체하부 유동저항 증가를 최소화해 쿨링드래그(Cooling Drag)를 더욱 낮출수 있는 차량 엔진룸 공기저항안정화장치를 제공함에 목적이 있다. In addition, an object of the present invention is to provide a vehicle engine room air resistance stabilizer that can further reduce the cooling drag by minimizing the increase in flow resistance under the vehicle body by forming an air dam in the engine room.

상기와 같은 목적을 달성하기 위한 본 발명은, 차량 엔진룸 공기저항안정화장치가 엔진룸내에서 라디에이터와 엔진사이로 형성된 공간에 설치되어 ECU로 제어되는 모터와 날개인 블레이드를 갖춘 팬과;The present invention for achieving the above object, the vehicle engine room air resistance stabilizer is installed in a space formed between the radiator and the engine in the engine room fan having a motor and a blade blade that is controlled by the ECU;

를 포함해 구성된 것을 특징으로 한다. Characterized in that configured to include.

상기 팬은 그 위쪽을 엔진쪽으로 기울어지게 경사진 상태로 설치한다. The fan is installed in a state inclined upwardly toward the engine.

상기 팬과 상기 플랩판은 하부를 가리지 않은 팬슈라우드로 가려진다. The fan and the flap plate are covered by a fan shroud that does not cover the lower part.

상기 플랩판은 공급된 전원을 통해 전자석으로 되어 공기흐름통로를 열도록 회전하는 전자석플랩으로 이루어지고, 상기 전자석플랩은 블라인드와 같은 구조로 이루어진다. The flap plate is made of an electromagnet flap that rotates to open an air flow passage through the supplied power, and the electromagnet flap is made of a blind-like structure.

상기 공기배출구는 차량전방의 그릴쪽에서 엔진룸의 하부를 따라 위치된 프론트언더커버와, 엔진쪽으로 이어지도록 엔진룸의 하부를 따라 위치된 엔진룸언더커버사이에서 엔진룸과 연통된다.The air outlet port communicates with the engine compartment between the front undercover located along the lower part of the engine room at the grill side of the vehicle front and the engine room undercover located along the lower part of the engine room to lead toward the engine.

상기 공기배출구에는 차량전방에서 들어오는 바람을 막는 에어댐을 더 구비한다. The air outlet further includes an air dam that prevents wind from entering the front of the vehicle.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명하며, 이러한 실시예는 일례로서 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 여러 가지 상이한 형태로 구현될 수 있으므로, 여기에서 설명하는 실시예에 한정되지 않는다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Since the exemplary embodiments of the present invention may be embodied in various different forms, one of ordinary skill in the art to which the present invention pertains may be described herein. It is not limited to the Example to make.

도 1은 본 발명에 따른 공기저항안정화장치를 차량 엔진룸에 설치한 구성도를 도시한 것인바, 본 발명은 후드(H)로 덮인 엔진룸(ER)내에서 라디에이터(R)와 엔진(E)사이로 형성된 공간에 설치된 팬(1)과, 상기 팬(1)의 뒤쪽에서 팬(1)을 통해 유입된 바람을 엔진(E)쪽으로 보내거나 차단하는 플랩판(6)과, 센서입력유닛(20)을 통해 차량주행정보를 얻어, 상기 팬(1)과 플랩판(6)을 제어하는 ECU(10)로 구성한다.1 is a block diagram showing the air resistance stabilizer according to the present invention installed in the vehicle engine room, the present invention is a radiator (R) and the engine (E) in the engine room (ER) covered with a hood (H) Fan 1 installed in the space formed between the fan, a flap plate 6 for sending or blocking the wind flowing through the fan 1 from the rear of the fan 1 toward the engine E, and a sensor input unit ( The vehicle 10 obtains vehicle driving information and controls the fan 1 and the flap plate 6 to configure the ECU 10.

본 실시예에서 상기 팬(1)은 그 위쪽을 엔진(E)쪽으로 기울이는 설치각(a)을 가지며, 상기 설치각(a)은 약 12도로 형성한다.In the present embodiment, the fan 1 has an installation angle a that is inclined upward toward the engine E, and the installation angle a is formed at about 12 degrees.

상기 팬(1)은 ECU(10)와 모터케이블(11)로 연결된 모터(2)와, 바람을 일으키는 날개인 블레이드(3)와, 회전되는 스테이터(4)로 이루어진다.The fan 1 is composed of a motor 2 connected by the ECU 10 and the motor cable 11, a blade 3 which causes wind, and a stator 4 that is rotated.

상기 팬(1)은 외부노출을 가리도록 팬슈라우드(5)를 더 갖추며, 상기 팬슈라우드(5)는 플랩판(6)을 결합한다.The fan 1 further has a fan shroud 5 to cover the external exposure, and the fan shroud 5 couples the flap plate 6.

본 실시예에서 상기 플랩판(6)은 소정형상의 케이스를 갖추고, ECU(10)와 전자석케이블(12)로 연결된 전자석을 구비하고, 다수로 구성해 블라인드와 같은 구조를 갖는 전자석플랩(6a)으로 이루어진다.In the present embodiment, the flap plate 6 has a case of a predetermined shape, has an electromagnet connected to the ECU 10 and the electromagnet cable 12, and consists of a plurality of electromagnet flaps 6a having a structure such as a blind. Is done.

상기 전자석플랩(6a)은 케이스 테두리에 끼워지는 구조를 가지며, 전자석형성시 회전되어 수평하게 배열됨으로써 플랩판(6)을 열고, 전자석 미형성시에는 수직하게 세워져 플랩판(6)을 닫아준다.The electromagnet flap (6a) has a structure that is fitted to the edge of the case, is rotated when the electromagnet is formed horizontally open to open the flap plate (6), when the electromagnet is not formed vertically to close the flap plate (6).

본 실시예에서는 차량 전방의 그릴(G)쪽에서 엔진룸(ER)의 하부를 따라 위치된 프론트언더커버(FUC)와, 엔진(E)쪽으로 이어지도록 엔진룸(ER)의 하부를 따라 위치된 엔진룸언더커버(EUC)사이로 엔진룸(ER)과 연통된 공기배출구(K)를 형성하고, 상기 프론트언더커버(FUC)쪽에서 공기배출구(K)에 돌출되어 공기흐름을 차단하는 에어댐(30)으로 더 형성한다.In the present embodiment, the front under cover FUC located along the lower part of the engine room ER on the grille G in front of the vehicle, and the engine located along the lower part of the engine room ER so as to extend toward the engine E. An air outlet K is formed between the room under cover EUC and the air outlet K communicating with the engine room ER, and protrudes from the front under cover FUC toward the air outlet K to block the air flow. To form more.

본 실시예에서 상기 센서입력유닛(20)은 차속과, 배기가스온도, 엔진회전수(RPM) 및 쓰로틀개도(TPS)이며, 각각의 센서신호는 ECU(10)로 전송된다.In this embodiment, the sensor input unit 20 is a vehicle speed, an exhaust gas temperature, an engine speed (RPM), and a throttle opening degree (TPS), and each sensor signal is transmitted to the ECU 10.

도 2는 본 발명에 따른 고속저부하조건 차량에서의 공기저항안정화장치의 작동도를 나타낸다.Figure 2 shows the operation of the air resistance stabilizer in a high speed low load condition vehicle according to the present invention.

도시된 바와 같이, 고속저부하조건은 100kph이상 주행속도로 큰 공력효과를 가짐으로써, 팬(1)을 구동하지 않고 플랩판(6)도 닫아준 상태이다.As shown, the high speed low load condition has a large aerodynamic effect at a traveling speed of 100 kph or more, thereby closing the flap plate 6 without driving the fan 1.

즉, ECU(10)가 센서입력유닛(20)을 통해 차속과, 배기가스온도, 엔진회전수(RPM) 및 쓰로틀개도(TPS)에 대한 정보를 입력받더라도, 차속이 100kph이상이면 ECU(10)는 팬(1)을 정지하고 플랩판(6)의 전자석플랩(6a)도 세워진 상태를 유지한 다.That is, even if the ECU 10 receives information about the vehicle speed, the exhaust gas temperature, the engine speed (RPM), and the throttle opening degree (TPS) through the sensor input unit 20, the ECU 10 if the vehicle speed is 100 kph or more. Stops the fan (1) and maintains the electromagnetic flap (6a) of the flap plate (6) upright.

이는, 고속저부하조건에서 차속이 100kph이상이면, 배기가스 온도가 낮아 엔진룸 열해가 없음에 기인한다.This is due to the low exhaust gas temperature and no engine room thermal damage when the vehicle speed is 100 kph or more under high speed and low load conditions.

이에 따라, 그릴(G)을 통해 엔진룸(E)으로 유입된 주행풍은 팬(1)을 지난후 플랩판(6)에 막혀 엔진(E)쪽으로 들어가지 못하지만, 유입된 주행풍은 상기 팬(1)과 플랩판(6)을 가린 팬슈라우드(5)의 하부에서 프론트언더커버(FUC)와 엔진룸언더커버(EUC)사이로 뚫린 공기배출구(K)를 통해 빠져나가게 된다.Accordingly, the running wind introduced into the engine room E through the grille G is blocked by the flap plate 6 after passing through the fan 1, and thus cannot enter the engine E. At the lower part of the fan shroud 5 covering the flap plate 6 and the flap plate 6, the air outlet K is opened between the front under cover FUC and the engine room under cover EUC.

상기와 같이 유입된 주행풍이 공기배출구(K)를 통해 빠져나감으로써, 쿨링드래그(Cooling Drag)를 크게 감소시키고, 엔진(E)쪽 인터퍼랜스 드래그(Interference Drag)도 최소화되며, 실험적으로 쿨링드래그(Cooling Drag)를 기존대비 약 0.024정도를 낮추고, 이에 따른 연비도 약 1% 이상 개선될 수 있다.As the traveling wind flows out through the air outlet K as described above, the cooling drag is greatly reduced, and the interference drag on the engine E side is also minimized. Lowering the cooling drag by about 0.024, and fuel efficiency can be improved by more than 1%.

또한, 프론트언더커버(FUC)쪽에서 공기배출구(K)에 돌출되어 전방에서 차량하부쪽으로 흐르는 공기가 에어댐(30)을 통해 꺾여짐으로써, 공기배출구(K)쪽으로 빠져나오는 공기흐름을 방해하지 않고 차체하부쪽 유동저항증가를 최소화하는 작용도 함께 일어난다.In addition, the air that protrudes from the front under cover (FUC) to the air outlet (K) and flows from the front to the lower part of the vehicle is bent through the air dam (30), thereby preventing the air flow out of the air outlet (K). The action of minimizing the increase in lower flow resistance also occurs.

도 3은 본 발명에 따른 고속 및 저속 고부하조건 차량에서의 공기저항안정화장치의 작동도를 나타낸다.Figure 3 shows the operation of the air resistance stabilizer in a high speed and low speed high load condition vehicle according to the present invention.

도시된 바와 같이, 고속 및 저속 고부하조건에서는 약한 공력효과를 갖고 높은 배기가스 온도로 엔진룸 열해를 발생함으로써, 팬(1)을 구동하고 플랩판(6)도 열어준 상태로 전환시킨다.As shown, under high load and high speed conditions, the engine room thermal damage is generated with a weak aerodynamic effect and a high exhaust gas temperature, thereby driving the fan 1 and switching the flap plate 6 to the open state.

즉, ECU(10)가 모터(2)를 구동해 주행풍을 유입시키고, 전자석플랩(6a)에도 전원을 공급해 세워 플랩판(6)을 열린 상태로 전원한다.That is, the ECU 10 drives the motor 2 to introduce running wind, supplies power to the electromagnetic flap 6a, and raises the flap plate 6 in an open state.

상기와 같은 조건에서 팬(1)의 뒤쪽으로 유입된 바람은 열려진 플랩판(6)을 통해 엔진(E)쪽으로 흘러들고, 동시에 상기 팬(1)과 플랩판(6)을 가린 팬슈라우드(5)의 하부에서 프론트언더커버(FUC)와 엔진룸언더커버(EUC)사이로 뚫린 공기배출구(K)를 통해 빠져나간다.Under the above conditions, the wind flowing into the rear of the fan 1 flows toward the engine E through the open flap plate 6 and at the same time the fan shroud 5 covering the fan 1 and the flap plate 6. At the bottom of), it exits through the air outlet (K), which is drilled between the front under cover (FUC) and the engine room under cover (EUC).

이와 같이 엔진룸(ER)으로 유입된 주행풍이 플랩판(6)을 통해 엔진(E)쪽으로 빠져나가 고온 배기가스로 인한 열해를 최소화하고, 동시에 공기배출구(K)쪽으로도 함께 빠져나가 주행풍으로 인한 쿨링드래그(Cooling Drag)와 엔진(E)쪽 인터퍼랜스 드래그(Interference Drag)도 줄여줄 수 있게 된다.In this way, the traveling wind flowing into the engine room ER escapes toward the engine E through the flap plate 6 to minimize thermal damage due to the high temperature exhaust gas, and simultaneously escapes toward the air outlet K as the driving wind. Cooling drag and interference drag on the engine E side can be reduced.

또한, 프론트언더커버(FUC)쪽에서 공기배출구(K)에 돌출되어 전방에서 차량하부쪽으로 흐르는 공기가 에어댐(30)을 통해 꺾여짐으로써, 공기배출구(K)쪽으로 빠져나오는 공기흐름을 방해하지 않고 차체하부쪽 유동저항증가를 최소화하는 작용도 함께 일어난다.In addition, the air that protrudes from the front under cover (FUC) to the air outlet (K) and flows from the front to the lower part of the vehicle is bent through the air dam (30), thereby preventing the air flow out of the air outlet (K). The action of minimizing the increase in lower flow resistance also occurs.
