본 발명은 공기냉각기가 설치된 자동차 공기압축장치에 관한 것으로, 상세히는 콤프레셔에서 토출되는 고온의 압축공기를 조기에 냉각시킴과 아울러 미량의 엔진오일과 수분을 걸러낼 수 있도록 한 것이다.The present invention relates to an automobile air compressor installed with an air cooler, and in particular, to cool early compressed air discharged from a compressor and to filter out a small amount of engine oil and water.

버스 등의 차량에서 브레이크장치나 도어개폐장치에는 압축공기를 사용하게 되는데, 종래에는 상기한 브레이크장치 및 도어개폐장치에 사용되는 압축공기를 생성 및 저장하는 공기압축장치가 제1도에 도시한 바와 같이 구성되어 있었으며, 이는 콤프레셔(1)에서 생성된 압축공기가 파이프라인(2)을 거쳐 에어드라이어(3)로 들어가고, 다시 퍼지탱크(4)를 경유하여 에어탱크(5)에 저장되는데, 에어탱크(5)의 압축공기는 일정압력이상이 되면 다시 에어드라이어(3)로 압력이 전달되어 퍼지탱크(4)내의 압축공기와 함께 에어드라이어(3)의 밖으로 배출되며, 이때 에어드라이어(3)의 내부에 들어있는 흡습제(도시안됨)는 통과공기의 수분을 흡수하였다가 건조공기의 배기에 의하여 수분을 배출하고 재생되도록 되어 있었다.In a vehicle such as a bus, compressed air is used for a brake device or a door opening and closing device. In the related art, an air compressor for generating and storing compressed air used in the brake device and the door opening and closing device is shown in FIG. It consists of the same, which is the compressed air generated in the compressor (1) enters the air dryer (3) via the pipeline (2), and is stored in the air tank (5) again via the purge tank (4), the air When the compressed air of the tank 5 is above a predetermined pressure, the pressure is transferred to the air dryer 3 again and discharged out of the air dryer 3 together with the compressed air in the purge tank 4. The moisture absorbent (not shown) contained in the inside absorbs moisture from the passing air and then discharges and regenerates the moisture by exhausting the dry air.

한편, 상기한 종래의 공기압축장치에 있어서는 콤프레셔(1)에서 생성된 압축공기가 통상 150℃내지 200℃정도의 고온상태로 배출되므로 에어드라이어(3)의 내부를 손상시키게 되는 문제점이 있었으며, 콤프레셔(1)의 작동시 미량의 엔진오일이 압축공기와 함께 에어드라이어(3)내부로 혼입되어 흡습제에 흡착되므로 흡습제의 흡습효과가 둔화되게 되어 자동차 브레이크장치 등에 상당한 영향을 끼치게 되어 브레이크장치의 작동불량 및 기능저하의 요인이 되어왔다.On the other hand, in the conventional air compressor, since the compressed air generated by the compressor 1 is discharged at a high temperature of about 150 ° C to 200 ° C, there is a problem of damaging the interior of the air dryer 3, During operation of (1), a small amount of engine oil is mixed with the compressed air into the air dryer (3) and adsorbed to the absorbent. Therefore, the absorbent effect of the absorbent is slowed down, which significantly affects the automobile brake system. And deterioration of function.

본 발명은 상기한 종래의 제반 문제점을 감안하여 안출된 것으로, 본 발명의 목적은 콤프레셔에서 토출되는 압축공기를 조기에 냉각시키고 압축공기내에 혼입된 미량의 엔진오일과 수분을 효과적으로 분리하여 에어드라이어의 수명연장은 물론 브레이크장치의 작동불량을 방지할 수 있도록 하는데 있는 것이다.The present invention has been made in view of the above-mentioned problems in the related art, and an object of the present invention is to prematurely cool the compressed air discharged from the compressor and to effectively separate a small amount of engine oil and water mixed into the compressed air. It is to extend the service life and to prevent the malfunction of the brake system.

이와 같은 목적을 달성하기 위하여 본 발명은 콤프레셔와 에어드라이어사이의 파이프라인에는 표면적이 넓고 내부에는 수많은 통공이 천공된 복수의 격판을 설치한 공기냉각기를 설치한 것으로, 이하, 본 발명의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하기로 한다.In order to achieve the above object, the present invention is to provide an air cooler having a plurality of diaphragms perforated in a large surface area in the pipeline between the compressor and the air dryer, a preferred embodiment of the present invention It will be described in detail by the accompanying drawings.

제2도는 본 발명의 일 실시예를 도시한 것으로, 본 발명은 콤프레셔(10)에서 생성된 압축공기가 파이프라인(20)을 거쳐 에어드라이어(30)로 들어가고, 다시 퍼지탱크(40)를 경유하여 에어탱크(50)에 저장되도록 한 자동차 공기압축장치에 있어서, 상기 콤프레셔(10)와 에어드라이어(30)사이의 파이프라인(20)둘레에는 냉각핀(22)을 부착하여 파이프라인(20)을 통과하는 고온의 압축공기가 1차적으로 냉각되도록 하고, 파이프라인(20)의 후단에는 통형의 공기냉각기(60)를 설치하여 입구측에 콤프레셔(10)에 연결된 파이프라인(20)을 접속시키고, 출구측은 에어드라이어(30)에 접속시킨 것이다.2 is a view illustrating an embodiment of the present invention, in which the compressed air generated in the compressor 10 enters the air dryer 30 through the pipeline 20 and passes through the purge tank 40 again. In the vehicle air compressor device to be stored in the air tank 50, the cooling fin 22 is attached to the circumference of the pipeline 20 between the compressor 10 and the air dryer 30, the pipeline 20 The compressed air of high temperature passing through the first to cool the first, and the rear end of the pipeline 20 is installed a cylindrical air cooler 60 to connect the pipeline 20 connected to the compressor 10 on the inlet side, The outlet side is connected to the air dryer 30.

상기 공기냉각기(60)는 둘레(62)를 요철형으로 형성하여 표면적을 넓게 하므로써 외부공기와의 열교환이 용이하도록 한 공냉식으로, 내부에는 수많은 통공(64)이 천공된 복수의 격판(66)을 설치하여 콤프레셔(10)로부터 공급된 압축공기에 포함된 미량의 엔진오일이 걸러지도록 한 것이고, 이와 아울러 고온의 압축공기가 공기냉각기내부에서 냉각되면서 압축공기내부의 수분이 응축되어 하부의 드레인(68)을 통하여 외부로 배출되도록 한 것이다.The air cooler 60 is air-cooled to facilitate heat exchange with external air by forming the circumference 62 to have a concave-convex shape to widen the surface area, and a plurality of diaphragms 66 having a plurality of holes 64 perforated therein. It is installed to filter a small amount of engine oil contained in the compressed air supplied from the compressor (10), and at the same time as the hot compressed air is cooled in the air cooler condensed moisture in the compressed air to drain the lower portion (68) It is to be discharged to the outside through).

이와 같이 구성된 본 발명은 콤프레셔(10)에서 토출되는 고온의 압축공기는 파이프라인(20)을 거치면서 파이프라인(20)의 둘레에 부착된 냉각핀(22)에 의하여 1차적으로 냉각되고, 공기냉각기(60)에서 2차적으로 냉각되어 에어드라이어(30)로 공급되어 에어탱크(50)에 저장되는 것이다.In the present invention configured as described above, the hot compressed air discharged from the compressor 10 is primarily cooled by the cooling fins 22 attached to the circumference of the pipeline 20 while passing through the pipeline 20, and air. Secondary cooling in the cooler 60 is supplied to the air dryer 30 is to be stored in the air tank (50).

또, 상기 공기냉각기(60)내에 설치된 격판(66)은 압축공기를 와류로 변화시켜 압축공기에 함유된 미량의 엔진오일을 흡착하는 것이며, 이와 함께 압축공기에 포함된 수분이 압축공기의 냉각에 의하여 응축되어 공기성분과 분리되는 것이다.In addition, the diaphragm 66 installed in the air cooler 60 absorbs a small amount of engine oil contained in the compressed air by changing the compressed air into vortex, and the moisture contained in the compressed air is used for cooling the compressed air. Condensed and separated from the air component.

이처럼 본 발명은 콤프레셔(10)에서 생성된 고온의 압축공기가 파이프라인(20)의 냉각핀(22)과 공기냉각기(60)에 의하여 냉각된 상태로 에어드라이어(30)로 공급되므로 에어드라이어(30)는 압축공기의 열에 의하여 파손되지 않게 되는 것이며, 이에 따라 에어드라이어(30)의 수명이 연장되는 것이다.As such, the present invention is supplied to the air dryer 30 in a state in which the compressed air of the high temperature generated by the compressor 10 is cooled by the cooling fins 22 and the air cooler 60 of the pipeline 20. 30 is not to be damaged by the heat of the compressed air, thereby extending the life of the air dryer (30).

또, 에어드라이어(30)로 공급되는 압축공기는 공기냉각기(60)에서 냉각 및 엔진오일과 수분이 미리 걸러지므로 에어드라이어(30)로 유입되는 압축공기내의 엔진오일함량이 감소되어 흡습제의 흡습기능이 향상되고 흡습제의 수명이 연장되는 것이다.In addition, since the compressed air supplied to the air dryer 30 is cooled in the air cooler 60, and the engine oil and moisture are filtered in advance, the engine oil content in the compressed air flowing into the air dryer 30 is reduced, so that the moisture absorbing function of the moisture absorbent is reduced. This will improve and extend the life of the absorbent.

또, 본 발명은 압축공기내의 수분 및 엔진오일이 공기냉각기(60)와 에어드라이어(30)에서 충분히 걸러지게 되므로 브레이크장치의 동작불량현상을 방지할 수 있는 것이다.In addition, the present invention can prevent the malfunction of the brake device because the moisture and engine oil in the compressed air is sufficiently filtered in the air cooler 60 and the air dryer 30.

이상 설명한 바와 같이 본 발명은, 콤프레셔와 에어드라이어사이의 파이프라인에 표면적이 넓고 내부에 수많은 통공이 천공된 복수의 격판을 설치한 공기냉각기를 구비한 것으로, 본 발명에 의하면 공기냉각기가 압축공기의 온도를 낮추고 엔진오일과 수분을 거르게 되므로 에어드라이어와 에어드라이어 내부의 흡습제의 수명을 연장시킬 수 있고, 압축공기를 사용하는 브레이크장치는 압축공기내에 엔진오일 및 수분의 함량이 적으므로 작동불량이 발생하지 않고 적절한 동작을 수행할 수 있는 유용한 효과를 갖는다.As described above, the present invention includes an air cooler having a plurality of diaphragms having a large surface area and perforated numerous holes in a pipeline between a compressor and an air dryer. As the temperature is lowered and the engine oil and water are filtered out, the life of the air dryer and the moisture absorbent inside the air dryer can be extended, and the brake device using the compressed air has a low content of engine oil and moisture in the compressed air, resulting in malfunction. It has a useful effect of performing proper operation without doing so.
