일반적으로 차량용 에어컨에 적용되는 배관 중 일부는 이중관 배관 구조를 갖는다. 이중관 배관은 차량의 에어컨 냉방을 증대하기 위해 사용하며, 외측관과 내측관으로 구성된다. 외측관은 외경 22.4mm, 두께 1.6t를 가지며, 내측관은 외경 19.0mm, 두께 1.6 내지 2.0t를 가진다.In general, some of the pipes applied to the vehicle air conditioner have a double pipe pipe structure. The double pipe pipe is used to increase the cooling of the vehicle's air conditioner and is composed of an outer pipe and an inner pipe. The outer tube has an outer diameter of 22.4 mm and a thickness of 1.6t, and the inner tube has an outer diameter of 19.0mm and a thickness of 1.6 to 2.0t.

도 1 및 도 2를 참조하면, 이중관 배관(1)의 내측관(10) 끝단부에 에어컨 호스(20)와 소켓(30)을 동시에 클램핑 또는 스웨징 공정을 통해 압착하게 된다.Referring to FIGS. 1 and 2 , the air conditioner hose 20 and the socket 30 are simultaneously compressed at the end of the inner pipe 10 of the double pipe pipe 1 through a clamping or swaging process.

또한, 상기 소켓(30)은 클램핑 또는 스웨징 공정을 통해 압착하게 되면, 외주면에 복수개의 소켓홈(40)이 형성되어, 상기 에어컨 호스(20)을 압착하게 된다.In addition, when the socket 30 is compressed through a clamping or swaging process, a plurality of socket grooves 40 are formed on the outer circumferential surface to compress the air conditioner hose 20 .

최근 차량의 전체 사이즈는 유사하나, 실내룸(사용자 공간)이 점점 커지고 있으며, 상대적으로 에어컨 배관이 위치하는 차량 엔진룸 내부공간이 협소해짐에 따라 이중관 배관의 사이즈를 축소해야 되는 문제점이 있다.Recently, although the overall size of the vehicle is similar, the indoor room (user space) is gradually increasing, and there is a problem in that the size of the double pipe pipe needs to be reduced as the internal space of the vehicle engine room where the air conditioner pipe is located is relatively narrow.
