본 발명은 차량의 엔진룸에 장착되는 전자제어유닛용 냉각장치에 관한 것으 로, 보다 상세하게는 차량의 엔진룸에 장착되는 전자제어유닛이 엔진룸의 고열에 의해 오동작이나 소손되는 것을 방지하기 위해 이를 냉각하는 차량의 엔진룸에 장착되는 전자제어유닛용 냉각장치에 관한 것이다.The present invention relates to a cooling device for an electronic control unit mounted in an engine room of a vehicle, and more particularly, to prevent the electronic control unit mounted in the engine room of a vehicle from being malfunctioned or burned out due to high heat of the engine room. It relates to a cooling device for an electronic control unit mounted in the engine room of the vehicle for cooling it.

근래, 전자공학 및 제어기술의 혁신적인 발전으로 차량의 컴퓨터화· 전자제어화가 가속화되고 있다. 특히 차량 전자제어 분야에 마이크로 프로세서가 응용되면서 하나의 전자제어유닛으로 여러 기능을 동시에 집중 제어할 수 있으며, 완전히 새로운 방식으로 고장진단상의 문제점의 근원을 도출하는데 탁월한 효과를 갖는다.In recent years, computerization and electronic control of vehicles have been accelerated by the innovative development of electronics and control technology. In particular, as the microprocessor is applied to the vehicle electronic control field, a single electronic control unit can control various functions at the same time, and it has an excellent effect in deriving the root cause of the problem in a completely new way.

이에 따라, 최근의 차량에는, 엔진을 제어하는 엔진제어용 전자제어유닛은 기본이고, 차체 제어용 전자제어유닛, 온도 제어용 전자제어유닛, ABS(Anti-lock Brake System)용 전자제어유닛, 자동변속기용 전자제어유닛, 현가장치용 전자제어유닛 등 여러 종류의 전자제어유닛이 장착되고 있는 추세이다.Accordingly, in recent vehicles, the engine control electronic control unit for controlling the engine is basic, the electronic control unit for body control, the electronic control unit for temperature control, the electronic control unit for anti-lock brake system (ABS), the electronics for automatic transmission Various types of electronic control units, such as control units and electronic control units for suspension devices, are being installed.

종전에는 이러한 전자제어유닛이 실내에 장착되어 있었으나, 대부분 엔진룸에 설치되는 각종의 센서와 전자제어유닛을 연결하는 신호선의 길이가 길어짐으로 인해 장착성이 나쁘고 신호가 미약해져 성능에 문제를 일으킴에 따라 점차적으로 전자제어유닛들 특히, 엔진제어용 전자제어유닛(Power Control Unit; "PCU")이 엔진룸에 장착되고 있는 추세이다.Previously, these electronic control units were installed indoors, but due to the length of the signal lines connecting the various sensors and electronic control units installed in the engine room, the mountability is poor and the signals are weak, causing performance problems. Increasingly, electronic control units, in particular, an engine control electronic control unit ("PCU") is being installed in the engine room.

이와 같이 전자제어유닛 특히, 엔진제어용 전자제어유닛을 엔진룸에 설치하면 미약한 신호를 걱정하지 않아도 되고 장착이 용이해지며 레이아웃의 설계가 편해지는 다양한 잇점이 있다.As such, when the electronic control unit, in particular, the engine control electronic control unit is installed in the engine room, there are various advantages of not having to worry about weak signals, making it easy to install, and making the layout easier.

그런데, 통상의 전자제어유닛은 온도에 매우 민감한 고집적회로소자로 이루 어져 있는데, 전자제어유닛을 엔진룸에 설치하게 되면, 엔진룸의 파워트레인 계통(엔진, 변속기 등)에서 발생하는 고열에 의해 전자제어유닛의 온도도 상승하게 되는 바, 전자제어유닛의 정상 작동을 보장하기 어렵다.By the way, the general electronic control unit is composed of highly integrated circuit elements that are very sensitive to temperature. When the electronic control unit is installed in the engine room, the electronic control unit uses the high temperature generated by the power train system (engine, transmission, etc.) of the engine room. Since the temperature of the control unit is also increased, it is difficult to guarantee the normal operation of the electronic control unit.

특히, 높은 외부기온에 의해 엔진룸의 온도가 최고조로 상승하는 여름철에는 전자제어유닛이 정상작동할 수 있는 온도범위를 초과하는 온도까지 상승하게 됨으로써, 전자제어유닛이 오동작하거나 소손될 수 있다.In particular, during the summer when the temperature of the engine room rises to the highest due to the high external air temperature, the electronic control unit may malfunction or be damaged by rising to a temperature exceeding a temperature range in which the electronic control unit can operate normally.

이에, 종래에는 전자제어유닛을 에어클리너 내에 장착함으로써 엔진으로 유입되는 공기에 의해 전자제어유닛을 냉각하도록 이루어져 있었다.Thus, conventionally, the electronic control unit is mounted in the air cleaner to cool the electronic control unit by the air flowing into the engine.

그런데, 상기와 같이 전자제어유닛을 에어클리너 내에 장착하게 되면, 에어클리너의 온도가 상대적으로 상승함으로써 공기밀도가 희박해져 엔진 출력이 저하되고 에어클리너의 설계 자유도를 제약하는 문제점이 있었다.However, when the electronic control unit is mounted in the air cleaner as described above, the temperature of the air cleaner rises relatively, so that the air density becomes thin, the engine output is lowered, and the design freedom of the air cleaner is limited.

이에 본 발명은 상기와 같은 종래기술의 문제점을 해소하기 위해 안출한 것으로, 엔진 출력에 지장을 주지 않고 엔진 룸 내의 다른 부품들의 설계에 제약을 주지않으면서 전자제어유닛을 효과적으로 냉각할 수 있는 차량의 엔진룸에 장착되는 전자제어유닛용 냉각장치를 제공하는 데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems of the prior art, a vehicle that can effectively cool the electronic control unit without affecting the design of other components in the engine room without affecting the engine output It is an object of the present invention to provide a cooling device for an electronic control unit mounted in an engine room.

To the brake 3.

예컨대, 디스크식의 휠 브레이크(3)의 경우, 브레이크 디스크 부위에 마찰로 인한 고열이 발생하므로, 배기 덕트(23)의 출구가 브레이크 디스크 부위를 향하도록 배치되는 것이 바람직하다.For example, in the case of the disc-type wheel brake 3, since high heat is generated due to friction at the brake disc portion, it is preferable that the outlet of the exhaust duct 23 is disposed so as to face the brake disc portion.

또한, 휠 하우징(2)의 관통홀(2a)에는 기체를 일방향으로만 유통하는 벤트홀부재(24)가 설치됨으로써 휠 하우징(2)으로부터 흙이나 먼지 등의 이물질이 배기 덕트(23)로 유입되지 않도록 이루어진다.In addition, a vent hole member 24 for distributing gas only in one direction is installed in the through hole 2a of the wheel housing 2 so that foreign matter such as dirt or dust flows from the wheel housing 2 into the exhaust duct 23. It is not done.
