Car condenser liquid storing pipe, connecting structure and machining process

Abstract

The invention relates to a car condenser liquid storing pipe, a connecting structure and a machining process. The liquid storing pipe comprises a liquid storing pipe and installation bosses installedon the liquid storing pipe body at intervals; each installing boss comprises a boss body, wherein the bottom end of the boss body is connected with a pipe wall of the liquid storing pipe body, the topend of the boss body is provided with a downwards-sinking arc face, a center hole is formed in the center of the arc face, and positioning bosses are arranged around the center hole; and a pipe wallof a flow gathering pipe is provided with through holes corresponding to the installing bosses, the arc faces of the installing bosses are matched with the pipe wall of the flow gathering pipe, and the positioning bosses extends to the inner sides of the through holes and are reversely buckled and fixed to the positions, around the through holes, of the pipe wall of the flow gathering pipe. By means of the structure, waste of liquid storing pipe section is reduced, the connecting strength of a liquid gathering pipe and the liquid storing pipe is high, and the welding process is simple.

Description

technical field [0001] The invention relates to an automobile condensing device, in particular to a liquid storage pipe of the automobile condensing device and a connection structure between the liquid storage pipe and a collecting pipe. Background technique [0002] The condenser is a part of the refrigeration system, which is a kind of heat exchanger, which can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube in a very fast way. The structure of the condenser mainly includes a collecting tube, a microporous flat tube, fins and a liquid storage tube, and the liquid storage tube and the collecting tube are connected to each other by brazing. [0003] In the prior art, more than one installation boss 11 is provided on the tube wall of the liquid storage tube 1, such as Figure 1-2 As shown, corresponding assembly holes and flat hole positions are provided on the corresponding positions of the collecting pipes. Among them, the instal...
