본 발명은 알루미늄 열교환기에 관한 것으로서, 보다 상세하게는 부품공용화를 통해 생산성이 향상되는 알루미늄 열교환기에 관한 것이다.The present invention relates to an aluminum heat exchanger, and more particularly, to an aluminum heat exchanger in which productivity is improved through component commonization.

일반적으로 알루미늄 열교환기는 열전도율이 높은 알루미늄 재질로 구성된것으로서, 도 1에 나타난 것과 같이 한쌍의 헤더 파이프(10)와, 상기 양 헤더 파이프(10)(10)를 서로 연통시켜 냉매를 유동시키는 다수개의 냉매튜브(12)와, 상기 냉매튜브(12)들 사이에 개재된 다수개의 전열핀(14)으로 이루어져 있다.In general, the aluminum heat exchanger is composed of an aluminum material having high thermal conductivity, and as shown in FIG. 1, a plurality of refrigerants for flowing a refrigerant by communicating a pair of header pipes 10 and both of the header pipes 10 and 10 with each other. It consists of a tube 12 and a plurality of heat transfer fins 14 interposed between the refrigerant tubes 12.

여기서, 상기 헤더 파이프(10)에는 내부공간을 수평으로 차단하여 유입된 냉매가 냉매튜브(12)를 통해 반대측 헤더 파이프(10)로 유동되도록 하는 다수개의 시퍼레이터(separator)(16)가 내장되어 있는데, 상기 시퍼레이터(16)는 좌우 헤더 파이프(10)에서의 위치가 서로 엇갈리도록 배치된다.Here, the header pipe 10 has a plurality of separators (16) are built in to block the internal space horizontally so that the introduced refrigerant flows through the refrigerant tube 12 to the opposite header pipe (10). The separators 16 are arranged such that their positions in the left and right header pipes 10 are staggered from each other.

상기 헤더 파이프(10)에는 냉매의 유입을 위한 냉매 유입포트(101)와, 냉매의 배출을 위한 냉매 배출포트(102) 또한 구비되어 있는데, 상기 냉매 유입포트(101)는 헤더 파이프(10)의 상단부에 위치되어 있으며, 냉매 배출포트(102)는 헤더 파이프(10)의 하단부에 위치되어 있다.The header pipe 10 is also provided with a refrigerant inlet port 101 for the introduction of the refrigerant, and a refrigerant discharge port 102 for the discharge of the refrigerant, wherein the refrigerant inlet port 101 of the header pipe 10 The coolant discharge port 102 is located at the lower end of the header pipe 10.

상술한 바와 같이 구성된 알루미늄 열교환기에 의하면 냉매 유입포트(101)를 통해 일측 헤더 파이프(10)의 상단으로 유입된 냉매가 냉매튜브(12)들을 통해 좌우 헤더 파이프(10)를 왕복 순환하여 아래로 흘러내린 다음 냉매 배출포트(102)를 통해 배출되는 과정에서 주위 공기와 열교환함으로써 냉각 또는 발열작용이 이루어진다.According to the aluminum heat exchanger configured as described above, the refrigerant flowing into the upper end of the one side header pipe 10 through the refrigerant inlet port 101 flows reciprocally through the left and right header pipes 10 through the refrigerant tubes 12 and flows downward. Cooling or exothermic action is achieved by lowering and then exchanging heat with ambient air in the process of being discharged through the refrigerant discharge port 102.

이와 같은 종래의 알루미늄 열교환기는 헤더 파이프(10)와 냉매튜브(12) 및 전열핀(14) 등의 각 구성요소를 별도로 성형하는 성형단계와, 성형된 각 구성요소를 단순결합시키는 조립단계와, 조립된 각 구성요소를 브레이징 등의 용접방법으로 융착시키는 용접단계를 거쳐 제작되는데, 조립단계에서는 냉매튜브(12)의 양선단을각각 좌우 헤더 파이프(10)의 측면에 삽입시키는 방식으로 헤더 파이프(10)와 냉매튜브(12)를 결합한 다음, 각 냉매튜브(12) 사이에 전열핀(14)을 끼워넣는 방식으로 각 구성요소를 조립하게 된다.Such a conventional aluminum heat exchanger is a molding step of separately molding each component, such as the header pipe 10, the refrigerant tube 12, and the heat transfer fins 14, an assembly step of simply coupling each of the molded components, Each assembled component is manufactured through a welding step of fusion welding using a welding method such as brazing. In the assembling step, the header pipes are formed by inserting both ends of the refrigerant tube 12 into the side of the left and right header pipes 10, respectively. 10) and the refrigerant tube 12 are combined, and then each component is assembled by inserting the heat transfer fins 14 between the respective refrigerant tubes 12.

한편, 열교환기는 필요로 하는 열교환 용량이나, 타부품과의 상관관계에 따라 다양한 크기로 제작되어야 하며, 알루미늄 열교환기의 경우에는 헤더 파이프(10)의 길이 및 냉매튜브(12)의 개수를 달리하는 방식으로 크기가 조절되는데, 상술한 바와 같은 종래기술에 의하면 다양한 크기의 열교환기를 구성하기 위해서는 각기 다른 길이의 헤더 파이프(10)를 필요로 하는 등 부품공용화율이 낮기 때문에 제품의 생산성이 떨어진다는 문제점이 발생한다.On the other hand, the heat exchanger should be manufactured in various sizes according to the heat exchange capacity required, or the correlation with other parts, in the case of the aluminum heat exchanger to vary the length of the header pipe 10 and the number of refrigerant tubes 12 The size is adjusted in a manner as described above, according to the prior art as described above requires a header pipe 10 of different lengths in order to configure a heat exchanger of various sizes, such that the productivity of the product is lowered because of the low component commonization rate This happens.
