적층형 열교환기Stacked Heat Exchanger

본 고안은 자동차용 공기조화기에 사용되는 적층형 열교환기에 관한 것이다.The present invention relates to a laminated heat exchanger used in an automotive air conditioner.

종래 적층형 열교환기로서 개시된 미국 특허번호 제5358034호의 냉매출입부에는 제1도 및 제2도에 도시한 바와 같이, 냉매를 안내하는 냉매관(1)의 단부를 수용하도록 서로 대응하는 한쌍의 수용관요소부(3,3')가 서로 용착하여 수용관부(5)를 형성하고 있고, 상기 수용관부(5)의 외주면에는 상기 냉매관(1)의 단부가 상기 수용관부(5)의 내부에 수용되어 용착될 때 상기 수용관요소부(3,3')가 서로 벌어지지 않도록 링부재(7)가 끼워져 용착되어 있다.The refrigerant inlet of US Patent No. 5358034, which is disclosed as a conventional stacked heat exchanger, includes a pair of receiving tubes corresponding to each other to accommodate an end portion of the refrigerant pipe 1 for guiding the refrigerant, as shown in FIGS. 1 and 2. Small portions 3 and 3 'are welded together to form a receiving tube portion 5, and an end of the coolant tube 1 is housed inside the receiving tube portion 5 on the outer circumferential surface of the receiving tube portion 5 The ring member 7 is fitted and welded so that the receiving tube element portions 3 and 3 'do not open to each other when they are welded.

이때, 냉매가 모여 흐르도록 한쌍의 튜브요소판(9,9')에 의해 형성되는 튜브의 하부에는 탱크용기부(11)가 형성되어 있고, 상기 수용관부(5)는 상기 탱크용기부(11)로부터 돌출되어 있다.At this time, the tank vessel portion 11 is formed at the lower portion of the tube formed by the pair of tube element plates 9 and 9 'so that the refrigerant flows together, and the accommodation tube portion 5 is the tank vessel portion 11. Protrude from).

그리고, 상기 링부재(7)가 상기 수용관부(5)에 끼워져 용착로에서 용착될 때 수용관부(5)의 외주면에 끼워진 링부재(7)가 기울어지는 것을 방지하도록 상기 수용관부(5)의 외주면에는 돌출된 다수의 엠보싱부(5a)가 형성되어 있고, 상기 냉매관(1)을 상기 수용관부(5)내에 삽입할 때 상기 냉매관의 단부면에 걸리어 삽입길이가 용이하게 맞춰지도록 상기 수용관부(5)의 내주면에는 돌출된 엠보싱부(5b)가 형성되어 있다.Then, when the ring member 7 is fitted to the receiving tube part 5 and welded in the welding path, the ring member 7 fitted to the outer circumferential surface of the receiving tube part 5 is prevented from inclining. A plurality of embossed portions 5a protruding from the outer circumferential surface are formed, and when the refrigerant pipe 1 is inserted into the accommodation pipe part 5, the insertion length is easily caught so that the insertion length is easily adjusted. The protruding embossing part 5b is formed in the inner peripheral surface of the accommodating pipe part 5.

이와 같이 구성된 종래의 적층형 열교환기에서 튜브요소판(9,9')의 수용관요소부(3,3')를 서로 밀착하여 임시로 수용관부를 형성시키고, 상기 수용관부(5)의 외주면에 링부재(7)를 끼워 엠보싱부(5a)에 걸리게 한 후, 상기 튜브요소판(9,9')을 서로 밀착된 상태로 유지시켜 용착로에서 용착하면, 수용관부(5)가 형성된다.In the conventional laminated heat exchanger configured as described above, the receiving tube element portions 3 and 3 'of the tube element plates 9 and 9' are brought into close contact with each other to temporarily form the receiving tube portion, and a ring is formed on the outer circumferential surface of the receiving tube portion 5.

다음에, 상기 가조립상태의 열교환기를 용착로에서 일체롤 브레이징하면, 적층형 열교환기가 완성된다. 이때, 용착로에서는 섭씨 580도 내지 섭씨 620도의 온도로 가열한다.Next, when the heat exchanger in the temporary assembled state is integrally brazed in the welding furnace, the laminated heat exchanger is completed. At this time, the welding furnace is heated to a temperature of 580 degrees Celsius to 620 degrees Celsius.

본 고안에 의한 적층형 열교환기는 용착로내에서 냉매관을 냉매출입부에 일체로 브레이징 하므로, 별도의 용접 및 납땜 작업이 불필요하므로 제조가 용이하고 간단하여 제조비가 절감되며, 그리고, 브레이징시 냉매관에 형성된 플랜지가 수용관부에 끼워져 요동없이 가조립되므로, 냉매출입부의 구조가 간단하다.The laminated heat exchanger according to the present invention brazes the refrigerant pipe integrally with the refrigerant inlet in the welding furnace, so that separate welding and soldering operations are unnecessary, so the manufacturing is easy and simple, and the manufacturing cost is reduced. Since the formed flange is fitted to the receiving tube and temporarily assembled without swinging, the structure of the refrigerant inlet and outlet is simple.
