Abstract
The utility model mainly provides a composite material which utilizing magnesium alloy, with the purpose to realize low cost and light weight. The magnesium alloy composite material comprises at least two layers, wherein the most inner layer is a corrosion proof layer, and forms a tubular, at least the other material layer is a magnesium alloy layer covering the most inner layer.
Description
Technical field
The utility model relates to the heat exchange field, as the manufacturing of domestic radiator section bar, the manufacturing of industrial heat exchanger section bar.
Background technology
At present the kind of radiator composite material is a lot, is divided into roughly that steel-aluminium is compound, steel-copper is compound, copper-aluminium is compound etc.Be to use two kinds of costs and the diverse metal material of heat conductivility inside and outside layer in a word, reach the reasonable balance of heat conductivility, weight and cost as composite material.
In composite heating radiator section bar field, the most frequently used aluminum alloy materials is compared with aluminium alloy, magnesium alloy has following characteristics: 1, the proportion of magnesium is less (about magnesium 1.8g/cm3, aluminium 2.6g/cm3), improved the metal thermal intensity of heat exchange, easier realization lightweight; 2, the heat transfer property of magnesium alloy is better than aluminium alloy; 2, the material cost of magnesium is lower than the aluminum cost, and is more economical; 3, magnesium alloy is than the easy shaping of aluminium alloy, so the processing of magnesium alloy profiles is easier than aluminium alloy.The above-mentioned advantage of magnesium alloy is compared with copper commonly used, and cost advantage is more obvious.
But because magnesium relatively active (especially meeting water), hardness is low, directly uses in traditional heat exchange field to have very big defective, does not still have the application example of magnesium alloy in traditional heat-dissipating type material at present, only in the wind-cooling heat dissipating system use is arranged.And the magnesium alloy that adds various components has changed the performance of magnesium, makes it have feasibility in the manufacturing of magnesium alloy composite material.
Summary of the invention
The utility model will provide a kind of composite material that uses magnesium alloy, realizes low-cost, lightweight.
For achieving the above object, the present invention adopts following technical scheme:
A kind of magnesium alloy heat radiation composite material comprises at least two layers, and innermost layer is etch resistant material layer, forms tubulose that another material layer covers described innermost layer for the magnesium alloy layer at least.
Wherein, described composite material comprises two-layer, and internal layer is an etch resistant material layer, and skin is the magnesium alloy layer;
Described resistant material is at least a in steel, stainless steel, copper, titanium or its alloy;
Wherein, the outer outer surface of composite material is provided with radiating ribs or radiating fin;
Inside and outside is interference fit between two-layer, is filled with heat-conducting medium in the fit-up gap between the ectonexine;
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Now in conjunction with the accompanying drawings and embodiments spirit of the present invention is done to describe in further detail:
As shown in the figure, composite material is by inside and outside two layers of material A, B is composited, inner layer material A is a resistant material, be preferably steel, stainless steel, copper, at least a in titanium or its alloy, wherein can be full of heat eliminating medium, the outer B of composite material is a magnesium alloy profiles, the radiating ribs that outer B outer surface can be set up different shape, to strengthen area of dissipation, improve radiating efficiency, the composite material of this structure, heat eliminating medium contacts with the internal layer resistant material during use, prevent that section bar is by dielectric corrosion, outer magnesium alloy does not directly contact with heat eliminating medium, therefore, and can be owing to the service life of the active properties influence section bar of magnesium.
Between the composite material ectonexine interference fit, and can be at two interlayers folder heat-conducting medium, heat-conducting medium is heat-conducting glue preferably, reduces thermal resistance more, improves the thermal efficiency.
The processing method of composite material: copper, the compound cold expanding method that adopts of magnesium alloy are compound; Steel, stainless steel etc. can adopt hot Compound Machining with magnesium alloy, also can adopt additive method, preferably guarantee between two-layer it is interference fit, reach effective heat conducting purpose.
In addition, composite material also can be a multilayer, and wherein the magnesium alloy layer is as the material of non-innermost layer.
Certainly, on the basis of the present invention's design, those skilled in the art can carry out various selections to magnesium alloy layer shape and thickness in the composite material, not necessarily are confined to embodiments of the invention.
Advantage of the present invention and effect are: low cost of manufacture, and the bearing capacity height, good heat conductivity, The section bar overall weight alleviates.
