Abstract

A preparation method of a heat exchanging metal composite pipe comprises the following steps of machining a foam metal material into a tubular shape to be attached on the outer surface of a mandrel bar; nesting the mandrel bar with the foam metal material into a metal pipe; penetrating the metal pipe through a circular hole mold with the inner diameter being smaller than the outer diameter of the metal pipe or through a circular hole mold with the inner diameter of an inlet end being greater than the outer diameter of the metal pipe and the inner diameter of an outlet end being smaller than the outer diameter of the metal pipe, utilizing a clamp to clamp one end of the metal pip to be pulled towards one side of the clamp; and finally drawing out the mandrel bar to obtain a hollow composite metal pipe which is internally lined with the foam metal material. The foam metal material also can be in other shapes such as a cylindrical shape rather than a tubular shape. The preparation method is simple in process, low in energy consumption, free from waste water, waste gas and industrial residue as well as other pollutants, environment-friendly and low in production cost; and the foam metal material of the prepared composite metal pipe is closely joined with the inner wall of the pipe, and the composite pipe is good in heat conduction effect and heat exchanging effect and high in strength.

Description

A kind of preparation method of heat exchange metal composite pipe
Technical field
The present invention relates to a kind of preparation method of heat exchange metal composite pipe.
Background technology
At present, when pipe applications, conduct heat and heat exchange property for improving, the one, adopt distinct methods to prepare the metal tube of inner wall coarse, comprise fluted tube, bellows, sintering metal tube cell etc.; The 2nd, adopt method for brazing to prepare the multiple tube of porous metals and metal tube.But the preparation method of above-mentioned heat pipe, particularly method for brazing, technological process is complicated, and energy consumption is higher, the cost height.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the deficiencies in the prior art, provides a kind of technical process simple, and energy consumption is low, the preparation method of the heat exchange metal composite pipe of the environmental protection that cost is low.
The technical scheme that the present invention solves its technical problem employing is:
A kind of preparation method of heat exchange metal composite pipe may further comprise the steps:
Foam metal material is processed into tubulose invests the plug appearance; To be placed in the plug of foam metal material in the metal tube again; Then metal tube is passed internal diameter less than the circular hole mould of metal tube external diameter or entrance point internal diameter greater than the circular hole mould (preferred entrance point internal diameter greater than described metal tube external diameter port of export internal diameter circular hole mould less than described metal tube external diameter) of described metal tube external diameter port of export internal diameter less than described metal tube external diameter, with an end of clamp metal tube, pull out to a layback of anchor clamps; At last plug is extracted out, obtained the hollow composite metal pipe of metal tube inner lining with foam metal material.
Described foam metal material can not be cylindric also, but cylindric, at this moment, the preparation method may further comprise the steps: the cylindrical foam metal material that diameter and metal tube internal diameter is suitable is placed in the metal tube; Then metal tube is passed internal diameter less than the circular hole mould of metal tube external diameter or entrance point internal diameter greater than the circular hole mould of described metal tube external diameter port of export internal diameter less than described metal tube external diameter, end with the clamp metal tube, layback to anchor clamps pulls out, and obtains the metal composite pipe that foam metal material is filled.
Described foam metal material preferred foams copper, nickel foam or foam copper nickel alloy, described metal tube are copper pipe, aluminum pipe or other tubing that can be plastically deformed.
Described foam metal material is the metal identical with described metal tube kind preferably; But also can make the heterogeneous foam metal material multiple tube that is difficult to by the preparation of technologies such as welding/bonding with this technology.
Among the present invention, the big I of the size of each parts and parameter is determined according to actual needs.
The present invention is a kind of mechanical cold-working Hubbing method, and technology is simple, and energy consumption is low, and pollutes generation without any the three wastes and other, but mould and the use of anchor clamps repeated multiple times, environmental protection, cost of manufacture is low; Because metal tube diameter in drawing mould diminishes, at metal pipe internal surface, the foam metal material of composite metal pipe engages with inside pipe wall closely foam metal, the heat conduction of multiple tube, good effect of heat exchange by expanded joint; Because foam metal material has changed the stress-strain behavior of metal tube, composite material strength is higher.
