Description

에어콘 시스템을 이용한 차량용 인터쿨러 {INTERCOOLER FOR VEHICLES USING AIRCON SYSTEM}Vehicle intercooler using air conditioning system {INTERCOOLER FOR VEHICLES USING AIRCON SYSTEM}

본 발명은 에어콘 시스템을 이용한 차량용 인터쿨러에 대한 것으로, 엔진으로 흡입되는 공기를 냉각시키되, 그 냉각수단으로 에어콘 시스템의 일부를 사용하는데 특징이 있는 것이다.The present invention relates to a vehicle intercooler using an air conditioner system, which cools the air sucked into the engine, and is characterized by using a part of the air conditioner system as the cooling means.

차량용 인터쿨러는 차량 엔진의 연소 효율을 높여 출력을 증강시키기 위한 장치로서, 주로 임펠러와 흡기 다기관 사이에 설치되어 과급된 공기를 냉각시키는 역할을 한다.The vehicle intercooler is a device for increasing the output by increasing the combustion efficiency of the vehicle engine, mainly installed between the impeller and the intake manifold serves to cool the supercharged air.

즉, 임펠러에 의해서 과급 된 공기는 온도가 상승함과 동시에 공기 밀도의 증대 비율이 감소하여 노킹이 발생되거나 충전 효율(charging efficiency)이 저하되는데, 이러한 현상을 방지하기 위하여 열교환기 구조로 설계하여 주행 중에 받는 공기로써 냉각시키는 공랭식과 냉각수를 순환시켜 냉각시키는 수냉식이 있다.In other words, the air charged by the impeller increases the temperature and decreases the rate of increase in the air density, causing knocking or reducing the charging efficiency. There are air cooling to cool by air received in the middle, and water cooling to cool by circulating cooling water.

주로 사용하는 공랭식 인터쿨러를 도 1에서 예시하였으며, 고온고압의 공기가 유입관(11)을 통해 유입되면, 공기에 의해서 냉각되는 다수의 튜브(21)와 핀(22)으로 이루어진 열교환부(20)를 통과하는 동안 냉각되어 유출관(12)으로 배출된 후, 엔진측의 흡기다기관으로 공급된다.The air-cooled intercooler that is mainly used is illustrated in FIG. 1, and when the high temperature and high pressure air flows through the inlet pipe 11, the heat exchange unit 20 includes a plurality of tubes 21 and fins 22 that are cooled by air. Cooled while passing through and discharged to the outlet pipe 12, it is supplied to the intake manifold on the engine side.

그러나 상기와 같은 종래의 인터쿨러는 고온 고압이 공기 밀도를 높이기 위해 가능한 큰 규모의 열교환부(20)가 필요하고, 따라서 규모가 큰 열교환부(20)는 생산원가가 높아질 뿐만 아니라 많은 공간을 차지하는 단점이 있으며, 무엇보다도 냉각 효율이 그다지 좋지 못하기 때문에 엔진 출력을 향상시키는데 어려움이 있었다.However, the conventional intercooler as described above requires a large heat exchanger 20 as large as possible to increase the air density at high temperature and high pressure. Therefore, the large heat exchanger 20 not only increases the production cost but also takes up a lot of space. There is a difficulty in improving the engine power, because above all, the cooling efficiency is not so good.

본 발명은 상기와 같은 종래의 문제점을 해결하고자 하는 것으로, 발명의 주된 목적은 자동차에 구비되는 에어콘 시스템 중에서 증발기로 가는 냉매의 일부를 냉각수단으로 사용하므로써 냉각효율을 극대화 시키고, 열교환부의 크기를 최소한으로 줄여 가볍고 공간을 차지하는 체적이 작아지도록 하는데 있다.The present invention is to solve the conventional problems as described above, the main object of the invention is to maximize the cooling efficiency by using a portion of the refrigerant going to the evaporator of the air conditioning system provided in the vehicle as a cooling means, at least the size of the heat exchange unit In order to reduce the weight, the space occupies to be small.

상기 목적을 달성하기 위한 본 발명의 특징적인 구성은 압축기에 의해 압축된 냉매가 응축기와, 리시버 드라이어와, 팽창밸브와 증발기를 거쳐 다시 압축기로 순환하는 통상의 자동차용 에어콘 시스템에 있어서, 상기한 증발기와 병렬로 연결된 증발기 코어를 별도로 마련한 후, 이 증발기 코어를 자동차 엔진의 흡기다기관으로 연결되는 압축공기 공급파이프의 속에 내장하여 고온 고압의 압축공기를 냉각시킬 수 있도록 하는 것이다.A characteristic configuration of the present invention for achieving the above object is a conventional automotive air conditioner system wherein the refrigerant compressed by the compressor is circulated back to the compressor via a condenser, a receiver drier, an expansion valve, and an evaporator. After separately preparing an evaporator core connected in parallel with the evaporator core, the evaporator core is embedded in a compressed air supply pipe connected to an intake manifold of an automobile engine to cool compressed air at high temperature and high pressure.

이하 본 발명의 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 실시예를 위한 증발기 코어(30)와 공급파이프(40) 구조를 보인 부분 단면도이고, 도 3은 본 발명의 에어콘 시스템을 포함한 전체 구성도이다.2 is a partial cross-sectional view showing the evaporator core 30 and the supply pipe 40 structure for an embodiment of the present invention, Figure 3 is an overall configuration diagram including an air conditioning system of the present invention.

상기 도 3에서 보듯이 엔진(50)에는 흡기다기관(51)이 있고, 이 흡기다기관으로 연결된 공급파이프(40)를 통해 고온/고압의 공기가 제공된다.As shown in FIG. 3, the engine 50 has an intake manifold 51, and air of high temperature / high pressure is provided through a supply pipe 40 connected to the intake manifold.

한편, 자동차용 에어콘 시스템(60)은 압축기(61)기에 의해 압축된 냉매가 응축기(62)에 의해 응축된 후, 리시버 드라이어(63)를 지나 팽창밸브(64)에 의해 팽창된 후, 증발기(65)에서 열을 빼앗으면서 증발되고, 다시 압축기(61)로 순환하여냉동사이클을 유지한다.On the other hand, in the automotive air conditioner system 60, after the refrigerant compressed by the compressor 61 is condensed by the condenser 62, is expanded by the expansion valve 64 after passing through the receiver dryer 63, the evaporator ( 65 is evaporated while depriving heat and circulated back to the compressor 61 to maintain a refrigeration cycle.

이때, 본 발명에서는 상기한 증발기(65)와 병렬로 연결된 증발기 코어(30)를 별도로 마련한 후, 이 증발기 코어(30)를 자동차 엔진(50)의 흡기다기관(51)으로 연결되는 압축공기 공급파이프(40)의 속에 내장시키는 것이다.At this time, in the present invention, after separately preparing an evaporator core 30 connected in parallel with the evaporator 65, the compressed air supply pipe is connected to the intake manifold 51 of the vehicle engine 50. It is embedded in 40.

즉, 팽창밸브(64)와 증발기(65)의 사이에서 냉매 파이프를 분리하여 증발기 코어(30)로 냉매가 공급되도록 연결하고, 다시 또 증발기 코어(30)로부터 증발기(65)와 압축기(61)의 사이로 냉매 파이프를 연결하여, 증발기(65)로 가는 냉매의 일부가 증발기 코어(30)로 순환하여 이 증발기 코어(30)도 주위 열을 빼앗을 수 있도록 병렬로 연결한다.That is, the refrigerant pipe is separated between the expansion valve 64 and the evaporator 65 and connected to supply the refrigerant to the evaporator core 30, and again from the evaporator core 30 to the evaporator 65 and the compressor 61. By connecting the refrigerant pipes between the portion of the refrigerant going to the evaporator 65 is circulated to the evaporator core 30 is connected in parallel so that the evaporator core 30 can also take away the ambient heat.

그리고 이와 같이 병렬로 연결된 증발기 코어(30)를 흡기다기관(51)으로 연결되는 공급파이프(40)속에 내장하는 것이다.In this way, the evaporator cores 30 connected in parallel are embedded in the supply pipe 40 connected to the intake manifold 51.

또한, 상기 증발기 코어(30)는 도 2에서 보는 바와 같이 알루미늄 또는 합성수지재 로 이루어진 공급파이프(40)의 내부에 내장된 형태로 어셈브리화 할 수 있다.In addition, the evaporator core 30 may be assembled into a form embedded in the supply pipe 40 made of aluminum or synthetic resin, as shown in FIG.

즉, 증발기 코어(30)의 냉매유입관(31)과 냉매유출관(32)을 기존의 냉매 파이프와 연결하기에 용이하도록 내장하고, 상기의 공급파이프(40) 양쪽 끝단도 기존의 흡기다기관(51)으로 연결되는 기존의 관체에 연결하기 용이하도록 환테부(41)를 형성하는 것이다.That is, the refrigerant inlet pipe 31 and the refrigerant outlet pipe 32 of the evaporator core 30 are built to be easily connected with the existing refrigerant pipe, and both ends of the supply pipe 40 are also provided with the existing intake manifold ( 51 is to form an annulus 41 to be easily connected to the existing tubular body connected to.

상기와 같이 설치된 본 발명의 에어콘 시스템을 이용한 차량용 인터쿨러는고온/고압의 공기가 공급파이프(40)를 지나는 동안 그 내부에 마련된 증발기 코어(30)에 접하므로써 비교적 신속하게 냉각되며, 냉각된 상태로 흡기다기관(51)을 거쳐 엔진(50)의 실린더로 공급되는 것이다.The vehicle intercooler using the air conditioner system of the present invention installed as described above is relatively quickly cooled by being in contact with the evaporator core 30 provided therein while the high temperature / high pressure air passes through the supply pipe 40, and is cooled. It is supplied to the cylinder of the engine 50 via the intake manifold 51.

위에서 상세히 설명한 바와 같은 본 발명의 인터쿨러는 에어콘 시스템의 증발기와 병열로 연결한 증발기 코어(30)를 이용하기 때문에 종래와 같이 큰 열교환부를 가진 인터쿨러가 필요치 않다.Since the intercooler of the present invention as described in detail above uses the evaporator core 30 connected in parallel with the evaporator of the air conditioning system, there is no need for an intercooler having a large heat exchanger as in the prior art.

따라서 별도의 공간을 확보할 필요가 없고, 제조원가가 매우 저렴하며, 인터쿨러의 성능이 크게 향상되는 등 여러 가지 장점을 가지는 것이다.Therefore, there is no need to secure a separate space, manufacturing cost is very low, and the performance of the intercooler is greatly improved, and has various advantages.
