The invention discloses a coaxial pipe for an automobile air conditioner. The coaxial pipe comprises an integrated coaxial pipe blank, the integrated coaxial pipe blank comprises an inner shaft pipe and an outer shaft pipe, the outer shaft pipe and the inner shaft pipe are connected through connecting ribs, and a high-pressure cavity is formed between every two adjacent connecting ribs; a left connecting part and a right connecting part are respectively formed at the left end and the right end of the inner shaft pipe; a left joint is connected between the left connecting part and the outer shaft pipe and is communicated with the high-pressure cavity; a right joint is connected between the right connecting part and the outer shaft pipe and is communicated with the high-pressure cavity; theleft joint and the right joint are connected with a high-pressure pipe, and the left connecting part and the right connecting part are connected with a low-pressure pipe. An integrated coaxial pipe structure is adopted, so that the heat exchange capacity of the coaxial pipe is greatly improved; the coaxial pipe can be miniaturized, so that the space is saved, and the coaxial pipe can be arranged in an engine compartment; and the structure is simple, assembling is easy, and batch production is easy.

    本发明公开了一种汽车空调用的同轴管,包括一体式同轴管坯,一体式同轴管坯包括内轴管和外轴管,所述外轴管和内轴管之间通过连接筋条相连接,相邻两个连接筋条之间形成高压腔;所述内轴管的左右两端分别形成左连接部和右连接部;左连接部与外轴管之间连接有左接头,左接与高压腔相连通;右连接部与外轴管之间连接有右接头,右接头与高压腔相连通;左接头和右接头上分别连接有高压管,左连接部和右连接部上分别连接有低压管。本发明采用一体式同轴管结构,大大增加了同轴管的热交换能力;可使同轴管微型化,节省空间,利于同轴管在发动机舱布置;结构简单,易于装配,易于批量生产。
