The invention discloses a manufacturing method of an automobile air conditioner coaxial pipe and the automobile air conditioner coaxial pipe. The automobile air conditioner coaxial pipe comprises a high-pressure outer pipe, a low-pressure inner pipe and a high-pressure branch pipe, and the manufacturing method comprises the following steps that through holes are formed in the pipe walls of the two ends of the high-pressure outer pipe; the low-pressure inner pipe is sleeved with the high-pressure outer pipe, and the two ends of the high-pressure outer pipe are buckled and pressed on the low-pressure inner pipe; and the high-pressure branch pipes are in one-to-one correspondence with the through holes and welded. According to the manufacturing method, a three-way connector can be omitted, material waste and cost are reduced, meanwhile, the machining technology and structure of the automobile air conditioner coaxial pipe are optimized, and the product quality is improved.

    本发明公开了一种汽车空调同轴管的制作方法及汽车空调同轴管,汽车空调同轴管包括:高压外管、低压内管及高压支管,制作方法包括以下步骤:在高压外管的两端的管壁上开设通孔;将高压外管套设于低压内管,且将高压外管的两端扣压于低压内管;将高压支管于通孔一一对应并焊接。本发明的制作方法能够取消掉三通接头,减少材料浪费和降低成本,同时优化汽车空调同轴管的加工工艺和结构,提升产品质量。
