The present invention relates to an air conditioner pipe for a vehicle, which includes: a refrigerant pipe part having a flow space through which the refrigerant flows; a fastening part to which the refrigerant pipe part is coupled; and a flange part having an insertion hole to which the fastening part is connected. According to the air conditioner pipe according to the present invention, a fastening member is applied between the refrigerant pipe part and the flange part and is formed of a plastic material so that an assembly method is simplified, and an assembly operation can proceed smoothly. As the refrigerant pipe part, the flange part, and the fastening member are combined by a heat fusion process, the airtightness of the refrigerant can be increased. Therefore, according to the air conditioner pipe according to the present invention, as the air conditioner pipe is formed of a plastic material, the weights of the refrigerant pipe part, the fastening part, and the flange part become lighter, thereby reducing the weight and cost of the vehicle. The flange part can be shared regardless of the diameter of the refrigerant pipe part, so it is possible to reduce the cost of the air conditioner pipe. In addition, since the fastening part and the flange part are integrally injection-formed, the defect rate is lowered by the simplified assembly method, thereby increasing the efficiency of air conditioner pipe production.
본 발명은, 냉매가 유동되는 유동공간이 형성된 냉매파이프부; 상기 냉매파이프부가 결합되는 체결부; 및 상기 체결부가 연결되는 삽입홀이 형성된 플랜지부;를 포함한다. 본 발명에 따른 에어컨 배관에 의하면, 냉매파이프부와 플랜지부 사이에 체결부재가 적용되며 플라스틱 소재로 형성됨으로써, 조립공법이 간소하게 되어 조립작업이 원활하게 진행이 가능하며 열융착 공정으로 냉매파이프부와 플랜지부 및 체결부재가 결합됨에 따라, 냉매의 기밀성을 증대시킬 수 있다. 따라서 본 발명에 따른 에어컨 배관에 의하면, 플라스틱 소재로 형성됨에 따라, 냉매파이프부와 체결부 및 플랜지부의 무게가 가벼워지게 되어 차량의 중량과 원가를 절감시키고 플랜지부는 냉매파이프부의 직경과 관계없이 공용화가 가능하여 에어컨 배관 비용절감이 가능하다. 또한, 체결부와 플랜지부는 일체형으로 사출 형성이 가능하여 간소화된 조립공법으로 불량률이 낮아지게 되어 에어컨 배관 생산의 효율성을 증대시킬 수 있다.
