Description

공기압축기의 실린더헤드{Cylinder head of air compressor}Cylinder head of air compressor {Cylinder head of air compressor}

본 발명은 자동차의 공기압축기에 관한 것으로, 보다 상세하게는 토출공기의 온도를 낮추기 위해 내부의 냉각수와 외부의 공기와 효과적으로 열 교환할 수 있도록 한 공기압축기의 실린더헤드에 관한 것이다.The present invention relates to an air compressor of a motor vehicle, and more particularly, to a cylinder head of an air compressor capable of effectively exchanging heat with internal coolant and external air to lower the temperature of discharged air.

일반적으로, 공기압축기는 엔진의 타이밍기어에 의해 엔진회전의 1/2로 구동되어 공기를 압축하는 왕복형 압축기이며, 압축된 공기는 공기탱크에 저장되어 공기현가장치에 사용되는 공기스프링이나 또는 공기 브레이크로 전달되어 작용하도록 되어 있다.In general, the air compressor is a reciprocating compressor driven by 1/2 of the engine rotation by the timing gear of the engine to compress the air, and the compressed air is stored in the air tank and used for the air suspension or air spring. It is intended to be delivered to the brake to act

또한, 상기 공기압축기는 팬을 이용하여 응축기에 바람을 불어주어 응축기와 공기의 온도차이에 따른 열교환 방식의 공냉식 압축기와, 응축기에 물을 분사하여 수증기 발생 응축기와 물의 온도차이에 따른 열교환 방식의 수냉식 압축기로 분류된다.In addition, the air compressor blows air to the condenser by using a fan, the air-cooled compressor of the heat exchange method according to the temperature difference between the condenser and the air, and the water-cooled type of heat exchange method according to the temperature difference between the steam generation condenser and water by injecting water into the condenser It is classified as a compressor.

한편, 차량용 엔진에 부착되어 구동되는 공기압축기는 에어탱크 압력이 8.5bar 정도 일 때 토출되는 공기의 온도는 최대 180℃ ∼ 220℃에 달한다. 토출 공기 내의 수분을 제거시키는 에어 드라이어(air dryer)는 최대 91℃ 이내에서 사용해야만 내구 신뢰성을 보장할 수 있기 때문에 토출공기 파이프는 최대한 길게 하여 주변 공기에 의해 냉각이 잘되도록 구성한다.On the other hand, the air compressor attached to the vehicle engine is driven when the air tank pressure is about 8.5bar temperature of the discharged air reaches a maximum of 180 ℃ ~ 220 ℃. Since the air dryer that removes moisture in the discharged air can be guaranteed to be durable only when used within a maximum of 91 ° C, the discharged air pipe is configured to be as long as possible to allow cooling by the surrounding air.

그런데, 최근에 차량에서 더 높은 압력의 공기를 요구함에 따라, 에어탱크 압력도 8.5bar에서 12.5bar 수준으로 높아지고 있다. 공기를 더욱 압축하게 되면 압력과 함께 온도도 상승되기 때문에 이 고온의 토출공기를 최대한 냉각해 준다.However, with the recent demand for higher pressure air in vehicles, the air tank pressure has also risen from 8.5 bar to 12.5 bar. As the air is further compressed, the temperature rises with the pressure, thereby cooling the hot discharge air as much as possible.

상기 공기압축기는 크랭크샤프트에 의해 관통되어 설치되는 실린더와, 이 실린더와 연결되는 공기흡입구 및 공기배출구가 각각 형성되면서 상기 실린더의 상부측에 설치되는 실린더헤드등으로 구성된다.The air compressor is composed of a cylinder penetrated by a crankshaft, an air inlet and an air outlet connected to the cylinder, respectively, and a cylinder head installed on the upper side of the cylinder.

도 1a는 종래기술에 따른 공기압축기의 실린더헤드의 측단면도이고, 도 1b는 종래기술에 따른 공기압축기의 실린더헤드의 평단면도이다.Figure 1a is a side cross-sectional view of the cylinder head of the air compressor according to the prior art, Figure 1b is a plan sectional view of the cylinder head of the air compressor according to the prior art.

In addition, one end thereof communicates with an external pipe, and the other end thereof is provided with external communication parts 26 and 28 connected to the cylinder communication part.

또한, 실린더헤드(10)의 안쪽에는 냉각수(30)가 흐르도록 되어 있어, 이 냉각수가 실린더헤드(10) 아래쪽의 공기와 열전달을 함으로써 공기를 냉각시킨다.In addition, the cooling water 30 flows inside the cylinder head 10, and the cooling water cools the air by conducting heat transfer with the air below the cylinder head 10.

그러나, 종래기술에 따른 공기압축기의 실린더헤드는 압축력이 12.5bar로 상승되면 에어 드라이어(Air Dryer) 입구에서의 온도를 목표하는 91℃까지 낮추려면 Air Dryer까지 매우 긴 Pipe를 부득이 설치해야 하는 번거로움이 있었다.However, the cylinder head of the air compressor according to the prior art has a cumbersome to install a very long pipe to the air dryer to lower the temperature at the air dryer inlet to 91 ℃ when the compression force rises to 12.5 bar There was this.

또한, 이러한 것은 좁은 엔진 룸에 설치하기도 까다로울 뿐 아니라, 비용이 상승하는 문제점이 있었다.In addition, this is not only difficult to install in a narrow engine room, but also has a problem of rising cost.

The suction valve 108 and the discharge valve 120 for opening and closing are installed.

그리고, 실린더헤드(100)에는 흡입밸브(108) 또는 토출밸브(20)의 개폐에 따라 외부배관(도시는 생략함)과 실린더 내부를 연결하는 유체의 유로로, 흡입포트(122)와 배출포트(124)가 형성되어 있다. 이 흡입포트(122)와 배출포트(124)는 실린더와 연결되는 유로로, 각각 그 일단부가 흡입공(102)과 토출공(104)에 연통되는 실린더연통부(도시는 생략함)를 구비한다. 또한, 그 일단부는 외부배관과 연통되고, 그 타단부는 실린더연통부와 연결되는 외부연통부(126, 128)가 마련된다.In addition, the cylinder head 100 is a fluid flow path connecting an external pipe (not shown) and the inside of the cylinder according to opening and closing of the suction valve 108 or the discharge valve 20, and the suction port 122 and the discharge port. 124 is formed.
