Description
본 고안은 자동차용 열교환기(heat exchanger)에 관한 것으로서, 더 상세하게는 압축된 냉매가스(冷媒gas)를 액화시키는 에어컨(air conditioner)의 응축기(condenser)와 엔진 또는 변속기 오일(oil)을 냉각시키는 오일쿨러(oil cooler)에 관한 것이다.The present invention relates to a heat exchanger for automobiles, and more particularly to cooling condenser and engine or transmission oil of an air conditioner to liquefy compressed refrigerant gas. It relates to an oil cooler (oil cooler).
냉각사이클(cooling cycle)을 이용하여 실내를 냉각시키는데 사용되는 에어컨은 압축기(compressor)에서 고온, 고압으로 압축된 냉매가스를 응축기에서 외기와의 열교환으로 액화시킨 뒤, 팽창밸브(expansion valve)를 통해 증발기(evaporator)에서 주변공기와의 열교환에 의해 기화시킴으로써 흡수되는 냉매의 기화열에 의해 냉각작용을 수행하는 공기조절장치이다.The air conditioner used to cool the room by using a cooling cycle liquefies the refrigerant gas, which has been compressed at a high temperature and high pressure in a compressor, by liquefying heat from the condenser to the outside air, and then through an expansion valve. It is an air conditioner that performs a cooling operation by heat of vaporization of a refrigerant absorbed by evaporation by heat exchange with ambient air in an evaporator.
이러한 에어컨은 자동차에 있어서도 여름철 차내의 냉방용으로 사용되고 있는데, 이는 냉매의 기화열에 의해 냉각작용을 수행하는 것이므로 그 냉각효율향상을 위해서는 특히 냉매가스의 응축효율을 높이는 것이 우선적으로 중요하다. 이를 위해 도 1에 도시한 바와 같이 자동차용 에어컨의 경우 엔진룸(engin room:R)의 최전방에 응축기(C)가 위치하게 된다.This air conditioner is also used for cooling the car in the summer season in the car, which is to perform the cooling action by the heat of vaporization of the refrigerant, so in order to improve the cooling efficiency, it is particularly important to increase the condensation efficiency of the refrigerant gas. To this end, as shown in FIG. 1, in the case of an air conditioner for a vehicle, the condenser C is positioned at the forefront of an engine room (R).
한편 자동차의 엔진과 변속기(transmission)에는 그 윤활과 기밀유지를 위해 오일(oil)이 충진되는데, 엔진이나 변속기는 작동중 상당한 고열이 발생되므로 그 작동중 오일의 점성이 저하되게 된다. 이로 인해 엔진이나 변속기 구성품들의 윤활과 기밀유지가 불량해질 뿐 아니라 심한 경우 유막파괴로 인한 부품손상이 야기되게 된다.On the other hand, the engine and transmission of an automobile are filled with oil for lubrication and airtightness, and since the engine or transmission generates a considerable heat during operation, the viscosity of the oil is reduced during the operation. This not only results in poor lubrication and airtightness of the engine or transmission components, but also, in severe cases, component damage due to film breakage.
이에 따라 도 1에 도시한 바와 같이 에어컨용 응축기(C)의 앞쪽으로 오일쿨러(L)를 구비하여, 엔진오일이나 변속기오일을 오일쿨러(L)와의 사이에서 순환시킴으로써 외기와의 열교환으로 적절히 냉각시키고 있기도 하다.Accordingly, as shown in FIG. 1, an oil cooler L is provided in front of the condenser C for the air conditioner, and the engine oil and the transmission oil are circulated between the oil cooler L and appropriately cooled by heat exchange with outside air. It is also possible.
그런데이 경우 응축기(C)와 오일쿨러(L)가 별개의 부품으로 구성되므로 제작공수가 많아 생산성이 낮을 뿐 아니라 재료의 낭비가 심해 원가가 크게 상승하는 문제가 있었다. 또한 엔진룸(R)에 응축기(C)와 오일쿨러(L)를 장착하기 위한 충분한 공간을 확보해야 하므로 엔진룸(R)의 공간활용도가 낮음은 물론 그 장착작업도 상당히 번잡한 문제가 있었다. 뿐만 아니라 오일쿨러(L)가 응축기(C)와 병렬로 배치되어 응축기(C)의 앞쪽으로 위치하므로 응축기(C)의 방열효율 저하가 초래되고, 이에 따라 에어컨의 냉각성능이 떨어지는 문제도 있었다.However, in this case, since the condenser (C) and the oil cooler (L) are composed of separate parts, there is a problem in that the cost is increased due to the high productivity and low waste of materials. In addition, the engine room (R) has to secure a sufficient space for mounting the condenser (C) and the oil cooler (L) because of low space utilization of the engine room (R), as well as the installation work was a very complicated problem. In addition, since the oil cooler L is disposed in parallel with the condenser C and positioned in front of the condenser C, the heat dissipation efficiency of the condenser C is lowered, thereby lowering the cooling performance of the air conditioner.
본 고안의 목적은 상술한 종래의 제반 문제들을 감안하여 압축기에서 압축된 냉매가스를 외기와의 열교환으로 액화시킴과 함께 엔진오일이나 변속기오일의 냉각작용도 동시에 수행함으로써 별도의 오일쿨러를 배제시킬 수 있는 자동차용 응축기/오일쿨러 일체형 열교환기를 제공하는 것이다.The object of the present invention is to liquefy the refrigerant gas compressed in the compressor by heat exchange with the outside air in consideration of the above-mentioned problems of the prior art, and also to cool the engine oil or the transmission oil at the same time, thereby eliminating the separate oil cooler. To provide an integrated heat exchanger for an automobile condenser / oil cooler.
이와 같은 목적을 달성하기 위해 본 고안에 의한 자동차용 응축기/오일쿨러 일체형 열교환기는, 상호 일정간격 이격되어 나란하게 배치되는 원통형의 제1 및 제2헤더(header)와, 이 제1,2헤더간에 나란하게 배열되어 각각에 연통하는 다수의 평판형 튜브(tube)와, 각 튜브들간에 개재되는 코러게이트형(corrugate)의 방열핀(放熱fin)과, 제1 및 제2헤더의 상단 또는 하단으로부터 일정간격 이격되며 상호 대향하도록 각각 설치되어 각각의 그 내부를 차단함으로써 냉매가 흐르는 냉매응축부와 자동차의 엔진오일 또는 변속기오일이 흐르는 오일냉각부로 구획하는 제1배플판(baffle)쌍과, 냉매응축부 쪽의 제1,2헤더에 대해 상호 교호적으로 배치되어 냉매가 복수의 튜브들을 재그재그 형태로 동시에 흐르도록 유도하는 복수의 제2배플판을 구비하여 구성되는 것을 특징으로 한다.In order to achieve the above object, the condenser / oil cooler integrated heat exchanger for automobiles according to the present invention includes cylindrical first and second headers arranged side by side and spaced apart from each other, and between the first and second headers. A plurality of flat tubes arranged side by side and communicating with each other, a corrugated radiating fin interposed between the tubes, and a constant from the top or bottom of the first and second headers. The first baffle plate and the refrigerant condensation unit which are spaced apart from each other and are respectively installed to face each other and block the inside thereof so as to partition the refrigerant condensation unit through which the refrigerant flows and the oil cooling unit through which the engine oil or transmission oil flows through the vehicle. And a plurality of second baffle plates arranged alternately with respect to the first and second headers on the side to induce the refrigerant to simultaneously flow in a plurality of tubes in a zigzag form. It shall be.
이에 따라 본 고안은, 종래와 같은 별도의 오일쿨러 없이 에어컨의 응축기만으로도 냉매의 액화작용은 물론 엔진오일이나 변속기오일등도 동시에 냉각시킬 수 있게 되므로 자동차의 제작성향상과 원가절감 및 그 에어컨의 방열효율 향상 등에 효과를 발휘한다.Accordingly, the present invention is capable of simultaneously cooling not only the liquefaction of the refrigerant but also the engine oil and the transmission oil without the need of a separate oil cooler as in the prior art, thus improving the production efficiency of the vehicle and reducing the cost and the room of the air conditioner. It is effective for improving thermal efficiency.
