Abstract
The utility model relates to a compound section in a steel and aluminium structure, which is extensively applied in the heat exchanger in all kinds of structural shape. The structure comprises an outer layer 1 of the aluminium section. A stainless inner layer 2 is interfering fit in the outer layer 1 of the aluminium section. The individual gap between the outer layer 1 of the aluminium section and the stainless inner layer 2 is filled with heat conductive medium 3. The steel and aluminium compound section is characterized by high heat efficiency, firmness and durability.
Description
Technical field
The utility model relates to composite material, and the composite material of a kind of steel-aluminum structure of more specifically saying so can be widely used in the heat exchanger of various structure shapes.
Background technique
At present, the general radiator overwhelming majority is ironcasting, Steel Work, stainless steel part or Al-alloy parts, and the deficiency of former three is heavy, is not easy to carrying and installation, and the latter's deficiency is not firm.For overcoming above-mentioned deficiency and further improving the thermal efficiency, released in the recent period the radiator of making of copper-aluminum composite section bar again, promptly copper pipe is fixed in the aluminum pipe with the pipe method that rises, the drawback of the radiator that this copper-aluminum composite section bar is made is: 1, owing to combination force between the copper aluminium is little, fixing insecure, thermal resistance is big, thereby the thermal efficiency is low; 2, the internal layer copper pipe is not corrosion-resistant, and working life is short.Above-mentioned two reasons cause with the radiator use value of copper-aluminum composite section bar making little.
Summary of the invention
The purpose of this utility model provides the high and robust steel-aluminium compound type material of a kind of thermal efficiency.
This steel-aluminium compound type material comprises the aluminium section bar skin, and its structural feature is that interference fit has the stainless steel internal layer in the outer field inner chamber of aluminium section bar.
Owing to be subjected to the influence of raw material processing technology, diverse location place at the outer surface of outer field internal surface of aluminium section bar and stainless steel internal layer, its slightly poor degree can be inequality, after outer and internal layer interference fit, there are indivedual positions always to have the gap that differs in size, influence thermal conductivity, for this reason, be filled with heat-conducting medium in the individual gaps between aluminium section bar skin and stainless steel internal layer.Heat-conducting medium comprises conduction oil and conductive powder.
The assembly technology of this steel-aluminium compound type material is: earlier with the outer heating of aluminium section bar, its inner cavity size is expand into greater than stainless steel inner layer outer surface size, the stainless steel internal layer that again outer surface is scribbled heat-conducting medium inserts, can realize the interference fit of aluminium section bar skin and stainless steel internal layer after the cooling, its value of interference fit is controlled in the scope of 0.02-0.20mm, because interference fit, heat-conducting medium just enters in the individual gaps between aluminium section bar skin and the stainless steel internal layer.
This steel-aluminium compound type material, the one, make full use of easily processing of aluminium, beautiful shape, in light weight, characteristic that thermal conductivity is big, make heat exchanger with it, volume is little, and is in light weight, thermal efficiency height; The 2nd, because the circulating water pH value of boiler is 10-12, be alkalescence, have corrosivity, and stainless steel is corrosion-resistant, with its internal layer as heat exchanger, long service life; The 3rd, the interference fit of skin and internal layer makes closely contact between the two on the one hand, and thermal conductivity is unaffected, has improved intensity on the other hand, and is sturdy and durable.Therefore, this steel-aluminium compound type material is used for heat exchanger, is the Updated product of heat exchanger.
Description of drawings
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings, and what wherein accompanying drawing drew is that the cross section is the structural representation of the steel-aluminium compound type material of circle, and the structure of the steel-aluminium compound type material of other shapes is identical.
Embodiment
With reference to accompanying drawing, the steel-aluminium compound type material of present embodiment comprises aluminium section bar skin 1, interference fit has stainless steel internal layer 2 in the inner chamber of aluminium section bar skin 1, is filled with heat-conducting medium 3 in the individual gaps between aluminium section bar outer 1 and stainless steel internal layer 2, and heat-conducting medium 3 is conduction oil or conductive powder.
Claims (3)
1, a kind of steel-aluminium compound type material comprises aluminium section bar skin (1), it is characterized in that interference fit has stainless steel internal layer (2) in the inner chamber of aluminium section bar skin (1).
2, steel-aluminium compound type material according to claim 1 is characterized in that being filled with heat-conducting medium (3) in the individual gaps between aluminium section bar skin (1) and stainless steel internal layer (2).
