본 발명은 고압 열교환기의 헤더에 관한 것이다.The present invention relates to a header of a high pressure heat exchanger.

일반적으로 열교환기는 온도가 높은 유체와 온도가 낮은 유체가 열교환기 벽면을 통해 높은 온도에서 낮은 온도로 열을 전달함으로써 열교환을 행하는 장치이다. 이러한 열교환기를 구성요소로 하는 에어컨 시스템의 작동매체로 HFC냉매가 주로 사용되어 왔으나, 이러한 HFC냉매는 지구 온난화의 주요 요인 중의 하나로 인식되어 그 사용에 대한 규제가 점차 확대되고 있다. 이러한 상황 하에서, HFC 냉매를 대체할 차세대 이산화탄소 냉매에 대한 연구가 활발히 진행되고 있다.In general, a heat exchanger is a device in which a high temperature fluid and a low temperature fluid transfer heat from a high temperature to a low temperature through a heat exchanger wall surface to perform heat exchange. HFC refrigerants have been mainly used as an operating medium of air conditioner systems having such heat exchangers, but such HFC refrigerants are recognized as one of the main factors of global warming, and regulations on their use are gradually being expanded. Under these circumstances, research on the next generation carbon dioxide refrigerant to replace the HFC refrigerant is being actively conducted.

이러한 차세대 냉매의 대표주자인 이산화탄소는, 지구 온난화 지수(GWP)가 HFC-R134a의 약1300분의 1에 해당되며, 작동 압축비가 낮아 압축효율이 우수하고, 열전달 성능이 매우 우수하여 2차 유체인 공기의 입구온도와 냉매의 출구온도 사이의 온도차이가 기존의 냉매에 비해 훨씬 작아질 수 있으므로 겨울철 낮은 외기 온도에서도 열을 뽑아 쓸 수 있으므로 여름철에는 냉방, 겨울철에는 난방 역할을 수행하는 히트펌프에도 적용가능하며, 체적냉방능력(증발잠열 x 기체밀도)이 기존의 냉매인 R134a의 7 ~ 8배에 달하기 때문에 압축기의 용량을 크게 줄일 수 있으며, 표면장력이 작아서 비등 열전달이 우수하고, 정압비열이 크고 점도가 낮아 열전달 성능이 뛰어나므로 냉매로서 우수한 열역학적 특성을 갖고 있다. Carbon dioxide, the representative of these next-generation refrigerants, has a global warming index (GWP) of about 1300th of HFC-R134a, and has a low compression ratio. As the temperature difference between the inlet temperature of the air and the outlet temperature of the refrigerant can be much smaller than that of the conventional refrigerant, the heat can be extracted even at a low outside temperature in winter, so it is also applied to a heat pump that performs cooling in summer and heating in winter. Since the volume cooling capacity (evaporative latent heat x gas density) is 7 to 8 times that of the existing refrigerant R134a, the capacity of the compressor can be greatly reduced. Because of its large and low viscosity, it has excellent heat transfer performance and thus has excellent thermodynamic properties as a refrigerant.

이산화탄소를 냉매로 사용하는 고압 열교환기는 기존의 HFC-R134a 냉매용 열교환기에 비해 약 10배 정도의 고압에서 작동되어 높은 내압성을 요구하므로 내압성을 높인 다양한 구조의 헤더가 개시되어 있다.Since a high pressure heat exchanger using carbon dioxide as a refrigerant requires high pressure resistance because it operates at about 10 times higher pressure than a conventional heat exchanger for HFC-R134a refrigerant, headers having various structures having increased pressure resistance have been disclosed.

도1은 종래 소재의 두께를 증가시켜 내압성을 확보하는 고압 열교환기의 헤더(10)를 나타낸다. 도시한 바와 같이, 두 개의 헤더요소(12)(14)가 그 사이에 유 로(R1, R2)가 형성되게 결합되어 용착되고, 일측의 헤더요소(12)에는 튜브가 끼워져 설치되는 튜브 삽입구멍(12a)이 형성되며, 상기 유로(R1)와 유로(R2)는 두꺼운 격벽(12b, 14b)에 의해 나누어져 헤더(10)의 강성을 높이게 된다. FIG. 1 shows a header 10 of a high pressure heat exchanger which ensures pressure resistance by increasing the thickness of a conventional material. As shown in the drawing, two header elements 12 and 14 are joined and welded so that flow paths R1 and R2 are formed therebetween, and a tube insertion hole in which a tube is fitted into one header element 12 is installed. 12a is formed, and the flow path R1 and the flow path R2 are divided by the thick partition walls 12b and 14b to increase the rigidity of the header 10.

상기한 바와 같은 종래 고압 열교환기의 헤더는 헤더 요소와 튜브와의 조립 및 브레이징이 용이하지 못하고 튜브 끝단이 안정되게 지지되지 못하므로 고압으로 인해 브레이징부가 손상될 우려가 있다는 문제점이 있었다.The header of the conventional high pressure heat exchanger as described above has a problem that the brazing part may be damaged due to the high pressure because the assembly and brazing of the header element and the tube are not easy and the end of the tube is not stably supported.

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 헤더와 튜브와의 조립 및 브레이징을 용이하게 하고 내압성을 높이는 고압 열교환기의 헤더를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a header of a high pressure heat exchanger that facilitates assembly and brazing of a header and a tube and increases pressure resistance.

본 발명에 의한 고압 열교환기의 헤더는, 상호 평행하게 이격되어 배치되고 양단부가 밀폐된 두 개의 헤더 사이에 복수개의 튜브가 연통되어 그 내부에 고압 냉매가 유동하는 고압 열교환기에 있어서, 상기 헤더는, 상기 튜브의 단부가 걸리는 튜브 스토퍼부가 형성된 헤더 몸체와, 상기 헤더 몸체의 개구부에 밀착하여 브레이징되도록 양면에 클래드 재가 코팅되며 상기 튜브가 삽입되는 튜브삽입구멍이 형성된 마감 플레이트와, 상기 마감 플레이트에 밀착하여 브레이징 되어 상기 헤더 몸체를 덮으며 상기 튜브가 삽입되는 튜브삽입구멍이 형성된 강화 플레이트로 이루어지는 것을 특징으로 한다.The header of the high pressure heat exchanger according to the present invention is a high pressure heat exchanger in which a plurality of tubes are communicated between two headers which are spaced apart in parallel to each other and whose both ends are closed so that a high pressure refrigerant flows therein. A header plate having a tube stopper portion on which an end of the tube is caught, a cladding material coated on both sides to be brazed in close contact with an opening of the header body, and a closing plate having a tube insertion hole into which the tube is inserted, and a close contact with the closing plate It is characterized by consisting of a reinforcing plate to be brazed to cover the header body and the tube insertion hole is inserted into which the tube is inserted.

상기 헤더 몸체의 내부 중간에는 상기 마감 플레이트에 밀착하여 지지하는 지지부가 돌출하여 형성되어 있다. 상기 지지부에는 상기 튜브의 단부가 끼워지는 삽입홈이 형성되어 있다.An inner middle portion of the header body is formed to protrude a support portion that is in close contact with the closing plate. The support portion is formed with an insertion groove into which the end of the tube is fitted.
