Mass production process for automobile heat-radiating adapter tube

Abstract

The invention belongs to the field of heat-radiating adapter tubes, and particularly relates to a mass production process for an automobile heat-radiating adapter tube. The automobile heat-radiating adapter tube comprises an upper adapter pipe and a lower adapter pipe, and the upper adapter pipe and the lower adapter pipe are directly provided with a diameter-variable communicating inclined pipe with an incline angle at 80-90 DEG. The upper adapter pipe, the lower adapter pipe and the diameter-variable communicating inclined pipe are made of composite materials. The outer surfaces of the upperadapter pipe, the lower adapter pipe and the diameter-variable communicating inclined pipe are made of stainless steel, and the inner surfaces of the upper adapter pipe, the lower adapter pipe and the diameter-variable communicating inclined pipe are made of a copper material. The invention provides the mass production process for continuous stamping. The mass production process of the inventionsolves the problem of poor pressure-bearing capacity in existing heat-radiating adapter tubes, and forms a structure with inside copper and outside stainless steel by using a diameter-variable featureand cooperating with the composite materials, so as to greatly improve structural stability and pressure-bearing capacity without affecting thermal conductivity of the heat- radiating tube.

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...
