Disclosed are a pipe connection member for a vehicle air conditioner and a manufacturing method thereof. In accordance with one embodiment, the pipe connection member for a vehicle air conditioner, which is provided in a hollow pipe form to connect a heat exchanger of a vehicle air conditioner with a fluid pipe, includes: a welding end part at one end welded by being inserted into a welding coupling hole formed on the heat exchanger; and an assembly end part at the other end fitted into an assembly coupling hole of the connector connecting the fluid pipe with the heat exchanger. An engaged protrusion for welding is provided to protrude from the outer periphery of the welding end part such that the outer circumference can be engaged with the surface of the heat exchanger on the outside of the welding coupling hole. An engaged protrusion for assembly is provided to protrude from the outer periphery of the assembly end part such that the inner circumference can be engaged with a support protrusion provided on the inner circumference of the assembly coupling hole of the connecto. The engaged protrusion for welding is provided through a forging process such that the circumference of one side of the welding end part can protrude outwards. Moreover, the engaged protrusion for assembly is provided through a cutting process such that the inner circumference surface can form a plane orthogonal to the outer surface of the assembly end part around the engaged protrusion for assembly.

    차량 공조기용 배관연결부재 및 그 제조방법을 개시한다. 일 실시 예에 따른 차량 공조기용 배관연결부재는 차량 공조기의 열교환기와 유체배관 사이를 연결하기 위해 중공의 관 형태로 마련되는 것으로, 상기 열교환기에 형성되는 용접결합공에 끼워져 용접되는 일단의 용접단부; 상기 유체배관을 상기 열교환기에 연결하는 커넥터의 조립결합공에 끼움 결합하는 타단의 조립단부;를 포함하고, 상기 용접단부의 외주에는 외측 둘레가 상기 용접결합공 외측의 상기 열교환기 표면에 걸리도록 용접용 걸림턱이 돌출하도록 마련되고, 상기 조립단부의 외주에는 내측 둘레가 상기 커넥터의 조립결합공 내주에 둘레에 마련되는 지지턱에 걸리도록 조립용 걸림턱이 돌출하도록 마련되며, 상기 용접용 걸림턱은 상기 용접단부의 일측 둘레를 외측으로 돌출하도록 단조 가공하여 마련되고, 상기 조립용 걸림턱은 내측 둘레면이 상기 조립용 걸림턱 주변의 상기 조립단부 외면과 직교하는 평면을 이루도록 절삭 가공하여 마련될 수 있다.
