Abstract
The utility model provides a spiral finned radiating pipe. The spiral finned radiating pipe comprises a radiating core pipe and fins, and is characterized in that each fin comprises a fin body and ferrules connected to the bottom edge of the fin body; the fin body and the ferrules are connected into a whole body spirally and sequentially; and all the ferrules are in tight fit with the surface of the radiating core pipe. Distances between the fins of the spiral finned radiating pipe depend on the width of the ferrules on the bottom edge of the fin bodies, so that the distances between the finsare equal, and the manufacture equipment and the manufacture process are also simpler. Compared with double helix forming process, the winding forming process of the spiral fins is simpler. The tensile force of the spiral fins is smaller, the spiral fins and the radiating core pipe are connected tighter, the fins formed by spiral winding are less susceptible to deform, and the uniformity of the fins is better. The utility model has the outstanding advantages of simpler processing technique, high production efficiency, and good product uniformity.
Description
Technical field
The utility model belongs to the heating radiator parts, particularly relates to a kind of helical fin radiating tube.
Background technology
The utility model of notification number CN2297699 " a kind of string sheet tube radiator " discloses a kind of heat spreader structures, it is made of string sheet pipe in housing, the housing and the header box that connects string sheet pipe, the sheet pipe that it is characterized in that going here and there adopt for having the string sheet pipe of ㄩ type double-spiral structure string sheet.Adopt this string sheet pipe not only can increase the contact area of fin and core pipe, make thermal resistance little, the heat exchanger effectiveness height, and production cost is reduced, and working (machining) efficiency improves greatly.
The string sheet pipe of above-mentioned radiator adopts double-stranded fin to have the complicated defective of processing technology, shows the difficult control of spacing between each spiral of screw winding moulding.In addition, the tension force of double helix fin coiled material is bigger, engages with the radiating core pipe to owe closely, and the fin after the screw winding moulding is yielding and uniformity is relatively poor.
Summary of the invention
The utility model be for solve adopt ㄩ type double-spiral structure fin string sheet pipe processing technique than the complicated technology problem, engage a kind of closely helical fin radiating tube with the core pipe and propose a kind of processing technology fin simple, screw winding.
The utility model adopts the string sheet pipe processing technique of ㄩ type double-spiral structure fin to take following technical scheme than the complicated technology problem for solving: this helical fin radiating tube comprises radiating core pipe and fin, it is characterized in that fin is made of fin body and the lasso that is connected in the fin body base, described each fin body and lasso thereof are the integral body that helical form connects successively, and described each lasso fluid-tight engagement is in the radiating core tube-surface.
The utility model can also be taked following technical measures:
Described radiating core pipe is a bimetallic extrusion modling pipe.
The beneficial effects of the utility model and advantage are: the spacing of fin of this helical fin radiating tube is by the width decision of fin body base lasso, so the spacing of fin unanimity, and process equipment and technology are also simpler.The winding moulding process of this helical fin is also fairly simple than the double helix moulding.This helical fin tension force is less, engages closelyr with the radiating core pipe, and the fin after the screw winding moulding is not yielding and uniformity is better.The utlity model has that processing technology is simple, production efficiency is high, the outstanding advantage of good product consistency.
Description of drawings
Accompanying drawing 1 example structure schematic diagram.
Accompanying drawing 2 fin body and lasso syndeton generalized section.
Number in the figure: 1 radiating core pipe, 2 fin body, 3 lassos.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in Figure 1, 2, this helical fin radiating tube comprises radiating core pipe 1 and fin, fin is made of fin body 2 and the lasso 3 that is connected in the fin body base, and each fin body and lasso thereof are the integral body that helical form connects successively, and each lasso fluid-tight engagement is in the radiating core tube-surface.
Radiating core pipe 1 of the present utility model can be aluminum pipe, steel pipe or copper pipe, also can be bimetallic extrusion modling pipe, for example copper aluminium compound extrusion forming pipe or steel aluminium compound extrusion forming pipe.
Claims (2)
1, a kind of helical fin radiating tube, comprise radiating core pipe and fin, it is characterized in that: fin is made of fin body and the lasso that is connected in the fin body base, and described each fin body and lasso thereof are the integral body that helical form connects successively, and described each lasso fluid-tight engagement is in the radiating core tube-surface.
2, helical fin radiating tube according to claim 1 is characterized in that: described radiating core pipe is a bimetallic extrusion modling pipe.
