Description

자동차용 에어컨의 응축기Condenser of car air conditioners

본 고안은 자동차용 에어컨(air conditioner)에 관한 것으로서, 더 상세하게는 압축된 냉매가스(冷媒gas)를 액화시키는 응축기(condenser)에 관한 것이다.The present invention relates to an air conditioner for an automobile, and more particularly, to a condenser for liquefying compressed refrigerant gas.

냉각사이클(cooling cycle)을 이용하여 실내를 냉각시키는데 사용되는 에어컨은 압축기(compressor)에서 고온, 고압으로 압축된 냉매가스를 응축기에서 액화시킨 뒤, 팽창밸브(expansion valve)를 통해 증발기(evaporator)에서 기화시킴으로써 냉매의 기화열에 의해 냉각작용을 수행하는 공기조절장치로서, 사회 전반에 거쳐 광범위하게 사용되고 있다.The air conditioner used to cool the room by using a cooling cycle liquefies the refrigerant gas, which has been compressed at high pressure and high pressure in the compressor, in the condenser, and then in the evaporator through an expansion valve. As an air conditioner that performs cooling by vaporization heat of a refrigerant by vaporizing, it is widely used throughout society.

예를 들어 자동차에 있어서도 여름철 차내의 냉방용으로 사용되고 있는데, 에어컨은 냉매의 기화열에 의해 냉각작용을 수행하는 것이므로 그 냉각효율향상을 위해서는 특히 냉매가스의 응측효율을 높이는 것이 우선적으로 중요한다.For example, even in automobiles, the air conditioner is used for cooling in a car in summer. Since the air conditioner performs cooling by the heat of vaporization of the refrigerant, in order to improve the cooling efficiency, it is particularly important to increase the measurement efficiency of the refrigerant gas.

도1에는 이러한 응축기의 일례로서 소위 SCC응축기(super compact condenser)를 개략적으로 도시하였다. 이것은 적정간격으로 이격된 원통형 또는 사각통형의 두 헤더(header:1,2) 사이에 냉매를 공기와 열교환시키는 다수의 튜브(tube:4)가 일정간격으로 배열되어 양 헤더(1,2)가 각각 연통하도록 고정된다. 이러한 각 튜브(4) 간에는 냉매의 방열을 촉진시키는 코러게이트(corrugate) 형상의 방열핀(放熱fin:5)들이 개재된다.FIG. 1 schematically shows a so-called super compact condenser as an example of such a condenser. This is because a plurality of tubes 4 for heat-exchanging refrigerant with air are arranged at regular intervals between two cylindrical or square cylindrical headers spaced at appropriate intervals. It is fixed to communicate with each other. Between each of these tubes 4, there are interposed radiating fins 5 in the form of corrugates that promote heat dissipation of the refrigerant.

한편 각 헤더(1,2)의 소정위치에는 헤더(1,2) 내에서의 냉매의 흐름을 차단하여 냉매가 복수의 튜브(4)들을 동시에 통과하도록 유도하는 배플(baffle:6)이 상호 엇갈리게 설치되어, 헤더(1,2)의 길이방향을 따라 냉매가 복수의 튜브(4)들을 동시에 통과하는 복수의 튜브군(5)들을 형성한다. 이러한 배플(B)은 냉매가 각 튜브군(3)을 진행함에 따라 압력이 강하되는 것을 억제하기 위해 그 유출측으로 갈수록 각 튜브군(3)들의 튜브(4)의 수량이 점차 감소하도록 배치된다. 나머지 부호 7은 압축기로부터 냉매가스가 유입되는 유입관이고, 8은 응축기를 통과한 액상냉매가 증발기로 유출되는 유출관이다.Meanwhile, at predetermined positions of the headers 1 and 2, the baffles 6 which block the flow of the refrigerant in the headers 1 and 2 to induce the refrigerant to pass through the plurality of tubes 4 at the same time are staggered. It is provided to form a plurality of tube groups 5 through which a refrigerant passes through the plurality of tubes 4 simultaneously along the longitudinal direction of the headers 1 and 2. The baffle B is arranged so that the quantity of the tubes 4 of the respective tube groups 3 gradually decreases toward the outlet side in order to suppress the pressure drop as the refrigerant proceeds through the respective tube groups 3. The remaining code 7 is an inlet tube through which the refrigerant gas is introduced from the compressor, and 8 is an outlet tube through which the liquid refrigerant passing through the condenser is discharged to the evaporator.

그런데 이러한 종래의 응축기는 두 헤더(1,2)가 그 각 부위에서 동일한 유동단면을 가지는 직선형태로 구성되므로, 한 튜브군(3)을 통과한 냉매가 헤더(1 또는 2)에서 직각으로 꺾이게 된다. 이로 인해 냉매의 흐름에 대한 유동저항이 상당히 커 압력강하량이 커지게 됨으로써 동력손실이 심할 뿐만 아니라 응축효율을 저하시키는 문제가 있었다. 이와 같은 문제는 특히 냉매의 흐름이 직각으로 꺾이는 두 헤더(1,2)의 양 단부와 배플(6)의 양 단부에서 더욱 심하게 나타난다.However, such a conventional condenser has two headers (1, 2) in a straight line shape having the same flow cross section at each part, so that the refrigerant passing through the tube group (3) is bent at right angles in the header (1 or 2) do. As a result, the flow resistance to the flow of the refrigerant is considerably large, resulting in a large pressure drop, resulting in a severe power loss as well as a problem of lowering the condensation efficiency. This problem is particularly acute at both ends of the two headers 1 and 2 and at both ends of the baffle 6 where the flow of the refrigerant is at a right angle.

본 고안의 목적은 상술한 종래의 문제들을 감안하여 냉매의 흐름에 대한 유동저항을 최소화함으로써 압력강하량을 줄여 소요동력을 감소시킬 수 있는 자동차용 에어컨의 응축기를 제공하는 것이다.It is an object of the present invention to provide a condenser for an automotive air conditioner which can reduce the required power by reducing the amount of pressure drop by minimizing the flow resistance to the flow of the refrigerant in view of the above-described conventional problems.

이와 같은 목적을 달성하기 위해 본 고안에 의한 자동차용 에어컨의 응축기는, 이격된 두 헤더와, 이 두 헤더간에 나란하게 배열되어 각각에 연통하는 복수의 튜브들로 이루어진 복수의 튜브군과, 각 튜브들간에 개재되어 냉매의 방열을 촉진시키는 방열핀과, 두 헤더에 대해 상호 교호적으로 배치되어 냉매의 흐름을 각 튜브군으로 순차 유도하는 복수의 배플을 구비하는 자동차용 에어컨의 응축기에 있어서, 한 튜브군을 통과한 냉매의 흐름이 후속되는 튜브군으로 전환되는 부위의 두 헤더의 외면이 각각 외측으로 볼록한 소정곡률의 곡면으로 구성되는 것을 특징으로 한다.In order to achieve the above object, a condenser of an automotive air conditioner according to the present invention includes a plurality of tube groups including two headers spaced apart and a plurality of tubes arranged side by side between the two headers and communicating with each other, and each tube. In a condenser of an automotive air conditioner having a heat dissipation fin interposed between the two to facilitate heat dissipation of the refrigerant, and a plurality of baffles disposed alternately with respect to the two headers to sequentially guide the flow of refrigerant to each tube group. The outer surface of the two headers of the portion where the flow of the refrigerant passing through the group is converted into a subsequent tube group is characterized by consisting of a curved surface of the predetermined curvature, respectively convex outward.

이러한 본 고안의 바람직한 특징에 의하면, 두 헤더의 각 곡면들이 상호 다른 곡률을 갖도록 구성된다.According to this preferred feature of the present invention, each curved surface of the two header is configured to have a different curvature.

이에 따라 본 고안은, 한 튜브군을 통과한 냉매가 소정의 곡률로 후속하는 튜브군으로 방향전환하게 됨은 물론 그 각 튜브들을 나온 냉매들이 혼합되는 부위의 단면적이 상대적으로 커 냉매의 흐름에 대한 유동저항이 최소화되게 되므로 자동차용 에어컨의 방열효율 향상과 소요동력 감소 등에 효과를 발휘한다.Accordingly, the present invention not only redirects the refrigerant passing through one tube group to the subsequent tube group with a predetermined curvature, but also has a relatively large cross-sectional area where the refrigerants coming out of the respective tubes are mixed with respect to the flow of the refrigerant. Since the resistance is minimized, it is effective in improving heat dissipation efficiency and reducing power consumption of the automotive air conditioner.

이와 같은 본 고안의 구체적 특징과 다른 이점들은 첨부된 도면을 참조한 이하의 바람직한 실시예의 설명으로 더욱 명확해 질 것이다.Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

도 2에서, 본 고안에 의한 자동차용 에어컨의 응축기는 적정간격으로 이격된 통형의 두 헤더(H1,H2) 사이에 냉매를 공기와 열교환시키는 다수의 튜브(T)가 일정 간격으로 배열되어 양 헤더(H1,H2)와 각각 연통하도록 접합된다. 이러한 각 튜브(T)들 간에는 바람직하기로 냉매의 방열을 촉진시키기 위한 코러게이트 형상의 방열핀(F)들이 개재된다.In FIG. 2, the condenser of the air conditioner for automobiles according to the present invention includes a plurality of tubes T for exchanging a refrigerant with air between two headers H1 and H2 of tubular spaced at appropriate intervals at regular intervals. It is joined so as to communicate with (H1, H2), respectively. Between each of the tubes (T) is preferably interposed a heat radiation fin (F) of the corrugated shape for promoting heat dissipation of the refrigerant.

또한 한 헤더(H1)의 상부에는 압축기로부터 냉매가스가 유입되는 유입관(P1)이 설치되고, 다른헤더(H2)의 하부에는 응축기를 통과한 액상냉매가 증발기로 유출되는 유출관(P2)이 설치된다.In addition, an inlet pipe P1 through which a refrigerant gas flows from a compressor is installed at an upper portion of one header H1, and an outlet pipe P2 at which a liquid refrigerant passing through a condenser is discharged to an evaporator is provided at a lower portion of another header H2. Is installed.

한편 각 헤더(H1,H2)의 소정위치에는 헤더(H1,H2) 내에서의 냉매의 흐름을 차단하여 냉매가 복수의 튜브(T)들을 동시에 통과하도록 유도하는 복수의 배플(B1∼B4)들이 상호 엇갈리게 설치되어, 헤더(H1,H2)의 길이방향을 따라 냉매가 복수의 튜브(T)들을 동시에 통과하는 복수의 튜브군(T1∼T5)들을 형성한다. 이러한 배플(B1∼B4)은 냉매가 각 튜브군(T1∼T5)들을 순차적으로 진행함에 따라 압력이 강하되는 것을 억제하기 위해 그 유출측으로 갈수록 각 튜브군(T1∼T5)들을 구성하는 튜브(T)의 수량이 점차 감소하도록 배치된다.On the other hand, a plurality of baffles B1 to B4 are formed at predetermined positions of the headers H1 and H2 to block the flow of the refrigerant in the headers H1 and H2 so that the refrigerant passes through the plurality of tubes T simultaneously. Staggered mutually, to form a plurality of tube groups (T1 to T5) through which the refrigerant passes through the plurality of tubes (T) at the same time along the longitudinal direction of the header (H1, H2). These baffles B1 to B4 are tubes T which constitute each tube group T1 to T5 toward the outlet side in order to suppress the pressure drop as the refrigerant proceeds through the respective tube groups T1 to T5 sequentially. ) Is arranged such that the quantity gradually decreases.

한편 본 발명의 특징에 따라 한 튜브군(T1∼T4)을 통과한 냉매가 후속하는 튜브군(T2∼T5)으로 흐름방향이 전환되는 부위의 두 헤더(H1,H2)는 그 외측면이 각각 외측으로 볼록하게 형성되는 소정곡률의 곡면(R1∼R4)으로 구성된다. 이와 같은 두 헤더(H1,H2)의 각 곡면(R1∼R4)들은 각 튜브군(T1∼T5)들을 구성하는 튜브(T)들의 수량이 각기 다른 바, 바람직하기로 각기 다른 곡률을 갖도록 구성된다.On the other hand, according to the characteristics of the present invention, the two headers H1 and H2 of the portion where the flow direction of the refrigerant passing through one tube group T1 to T4 is changed to the subsequent tube group T2 to T5 are respectively outer side surfaces thereof. It consists of curved surfaces R1-R4 of predetermined curvature formed convexly outward. Each of the curved surfaces R1 to R4 of the two headers H1 and H2 is configured to have different curvatures because the quantities of the tubes T constituting the respective tube groups T1 to T5 are different. .

즉 각 튜브군(T1∼T5)은 냉매의 진행방향으로 갈수록 그 튜브(T)의 수량이 점차 감소하도록 구성되는 바, 냉매의 방향전환 부위의 길이가 점차 감소되어 각 튜브군(T1∼T5)으로 진행할수록 냉매의 방향이 급전환되게 되므로 냉매의 흐름에 대한 유동저항을 최소화함과 동시에 그 원활한 흐름을 위해 후속하는 튜브군(T1∼T5)으로 갈수록 두 헤더(H1,H2)의 각 곡면(R1∼R4)들의 곡률이 점차 작아지도록 구성되는 것이다. 또한 두 헤더(H1,H2)의 각 곡면(R1∼R4)들은 바람직하기로 냉매의 방향전환에 대한 유동저항이 최소화되는 곡률로 구성된다.That is, each tube group (T1 to T5) is configured such that the amount of the tube (T) gradually decreases in the direction of travel of the refrigerant, the length of the redirection portion of the refrigerant is gradually reduced to each tube group (T1 to T5) As the direction of the refrigerant changes rapidly, the flow resistance of the refrigerant is minimized, and at the same time, the curved surfaces of the two headers H1 and H2 are gradually moved to the subsequent tube groups T1 to T5 for the smooth flow. The curvature of R1 to R4) is configured to gradually decrease. In addition, each of the curved surfaces R1 to R4 of the two headers H1 and H2 is preferably configured to have a curvature that minimizes the flow resistance to the redirection of the refrigerant.

이와 같은 구조적 특징에 따라 본 고안에 의한 자동차용 에어컨의 응축기는 한 튜브군(T1∼T4)들을 통과한 냉매가 후속하는 튜브군(T2∼T5)들로의 방향전환시 그 각 튜브(T)들을 나온 냉매들이 혼합되는 부위의 단면적이 상대적으로 커 그 흐름에 대한 유동저항이 최소화됨은 물론 두 헤더(H1,H2)의 곡면(R1∼R4)들이 냉매흐름의 유동가이드 역할을 하게 된다. 이에 따라 냉매의 압력강하량이 최대한 억제되게 되어 냉매가 매우 원활하게 흐르게 됨으로써 소요동력을 최대한 줄일 수 있게 된다.According to this structural feature, the condenser of the air conditioner for automobiles according to the present invention comes out of each tube T when the refrigerant passing through one tube group T1 to T4 is redirected to the subsequent tube group T2 to T5. As the cross-sectional area of the portion where the refrigerant is mixed is relatively large, the flow resistance to the flow is minimized, and the curved surfaces R1 to R4 of the two headers H1 and H2 serve as flow guides of the refrigerant flow. Accordingly, the pressure drop of the refrigerant is suppressed to the maximum, and the refrigerant flows very smoothly, thereby reducing the required power as much as possible.

또한 튜브군(T1∼T5)들의 각 튜브(T) 내에서의 압력불균형이 효과적으로 해소되어 보다 균일한 유량분배가 이루어지게 되며, 이에 따라 응축기의 집적도가 향상되게 된다.In addition, the pressure imbalance in each tube T of the tube groups T1 to T5 is effectively resolved to achieve a more uniform flow rate distribution, thereby improving the degree of integration of the condenser.

이상에서 살펴본 바와 같이 본 고안에 의하면, 방향전환되는 헤더 내에서의 냉매의 흐름에 대한 유동저항을 최소화할 수 있으며, 이에 따라 냉매의 압력강하량을 최대한 억제할 수 있음은 물론 소요동력을 최소한으로 줄일 수 있게 된다. 따라서 본 고안은 자동차용 에어컨의 냉각성능과 신뢰성 등을 크게 향상시키는 매우 우수한 효과가 있다.As described above, according to the present invention, it is possible to minimize the flow resistance to the flow of the refrigerant in the header to be redirected, thereby minimizing the pressure drop of the refrigerant as much as possible and reducing the required power to the minimum. It becomes possible. Therefore, the present invention has a very excellent effect of greatly improving the cooling performance and reliability of the automotive air conditioner.
