Description

차량용 에어컨 배관{Automotive air conditioning piping}Automotive air conditioning piping

본 발명은 차량용 에어컨 배관에 관한 것으로, 더욱 상세하게는, 이중관 배관의 내측관과 호스부를 연결하는 구조를 적용한 차량용 에어컨 배관에 관한 것이다.The present invention relates to a vehicle air conditioner piping, and more specifically, to a vehicle air conditioner piping that applies a structure for connecting an inner tube and a hose portion of a double-tube piping.

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.Some piping commonly used in vehicle air conditioning systems has a double-pipe structure. Double-pipe piping is used to enhance cooling performance of vehicle air conditioning systems and consists of an outer tube and an inner tube. The outer tube has an outer diameter of 22.4 mm and a thickness of 1.6 t, while the inner tube has an outer diameter of 19.0 mm and a thickness of 1.6 to 2.0 t.

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 clamped or compressed to the end of the inner tube (10) of the double-tube pipe (1) through a 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 surface, thereby compressing 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.Although the overall size of recent vehicles is similar, the interior room (user space) is getting larger, and the space inside the vehicle engine room where the air conditioning pipe is located is getting narrower, so there is a problem that the size of the double-pipe pipe must be reduced.
