A mass production process of automobile cooling pipes

Abstract

The invention belongs to the field of heat dissipation pipes, and specifically relates to a mass production process of automobile heat dissipation pipes. The automobile heat dissipation pipes include an upper pipe and a lower pipe. The inclination angle of the diameter connecting inclined pipe is 80‑90°. The upper connecting pipe, the lower connecting pipe and the variable diameter connecting inclined pipe are all made of composite materials, and the outer surface is made of stainless steel material, and the inner surface is made of copper material, and continuous stamping is provided. mass production process. This method solves the problem of poor pressure-bearing capacity of the heat dissipation connecting pipe in the prior art, and utilizes the characteristics of variable diameter, supplemented by composite materials to form a structure of inner copper and outer stainless steel, which greatly improves the structural stability without affecting the thermal conductivity of the heat dissipation connecting pipe. Sexuality and resilience.

Description

technical field [0001] The invention belongs to the field of heat dissipation pipes, and in particular relates to a mass production process of automobile heat dissipation pipes. Background technique [0002] Heat dissipation pipes are an important part of automobile radiators, and the materials generally used are copper or aluminum. Copper radiators are mainly used in passenger cars, construction machinery, heavy trucks, etc.; aluminum radiators are mainly used in cars and various light car. There are various manufacturing methods for soldering-based heat sinks. These methods involve the following processes: roll bending of metal strip to form channels; application of flux to the surface of the roll-formed open pipe; welding, in which the flux cleans the metal surface during the heating The welding material flows into the fitting joints and cools to form a tight weld. [0003] Aluminum or copper cooling tubes have average pressure bearing capacity, and are prone to deform...
