Abstract

The invention discloses a heat dissipation material for air cooling tubes, which comprises a substrate, a heat conduction layer and a soldering layer which are sequentially arranged from bottom to top. The soldering layer can greatly lower the soldering temperature of the material during soldering, saves the energy and enhances the economic benefit.

Description

technical field [0001] The invention relates to an aluminum-steel composite material, in particular to an aluminum-steel composite material for an air-cooled heat dissipation pipe, and also to a manufacturing method of the aluminum-steel composite material. Background technique [0002] At present, the material of the air-cooled heat dissipation pipe requires high strength. At present, the steel strip material is mainly used, but the melting point of the steel strip material is high, and the welding operation is very demanding, which makes the subsequent brazing process complicated. Therefore, it is chosen to use aluminum alloy and steel for compounding, and the problem of low melting point of aluminum alloy is used to ensure the effective brazing. With the development of society and the improvement of energy saving and emission reduction requirements, air-cooled materials urgently need to improve economic benefits by continuously reducing energy consumption during brazing. ...
