Abstract

The utility model relates to a radiating element compounded by pipe plates, which belongs to a radiating element. The utility model solves the technical problem of the design of a pipe plate composite radiating element with low price and small demanded expanding coupling torque. The utility model has the technical scheme that the utility model comprises a pipe and fins arranged on the surface of the pipe. The utility model is characterized in that the cross-sectional shape of the pipe is formed by at least four curves which are in end-to-end connection. Straight barrel fins matched with the cross-sectional shape of the pipe are uniformly combined on the outer surface of the pipe. The cross section of the pipe has two ends in the shape of semi circular arc and two curve sides with the curvature radius which is larger than the radius of the semi circular arc. The utility model is mainly used for making radiators for rooms.

Description

The heat dissipation element that a kind of section of jurisdiction is compound

Technical field:

The utility model relates to a kind of heat dissipation element, the compound heat dissipation element in particularly a kind of section of jurisdiction.

Background technology:

The heating installation heat dissipation element that now general room is used mostly is cylindricality cast iron fin, aluminium section bar fin, the more general limit of the low use of the former price.Mount on the more suitable wall of the latter, save usable floor area, but that both common drawback are radiating effects is relatively poor.The compound heat dissipation element of section of jurisdiction expanded joint that air-conditioner is used, its radiating efficiency height adopts copper tube aluminum more, or the aluminum pipe aluminium flake, owing to copper, aluminium price height, should not popularize use in family of common wage-earners.The compound heat dissipation element of this section of jurisdiction expanded joint, the expanding joint method of employing are that caliber is increased the section of jurisdiction swelling, reduce the thermal resistance between the section of jurisdiction.Obtain high cooling efficiency, the expanded joint power that the expanding joint method of this increase caliber needs is big, for price low steel pipe and the compound heat dissipation element of aluminium flake expanded joint, guarantee the essential steel pipe that adopts wall thickness of long-life of pipe fitting, even wall thickness is 1 millimeter a steel pipe, it is very big to make its diameter increase 0.5 millimeter required expanded joint strength, needs the hydraulic press that tonnage reaches thousands of tons of.

Summary of the invention:

The utility model technical issues that need to address are the low little compound heat dissipation elements in section of jurisdiction of required expanded joint power of a kind of price of design.The technical solution of the utility model is, the heat dissipation element that a kind of section of jurisdiction is compound, it comprises pipe and its lip-deep fin, the shape of cross section that it is characterized in that pipe is made up of at least four end to end curves, is provided with the straight tube fin that the shape of cross section with pipe matches and evenly is compounded on the outer surface of pipe.A kind of cross sectional form of pipe is that two ends are semi arch, and its both sides are radius of curvature curves greater than the semi arch radius.The utility model is because the pipe that has adopted cross section to be made up of a plurality of curves, the transversal facial canal of the polygon of available a plurality of rectilinear(-al)s obtains by the method for hydraulic pressure or mechanical expanded joint, thereby this required deformation force of method that becomes curve with straight line to increase direct expanded joint power much little, both resultant bulks or pipe are identical with the degree of packing tightly of fin, thereby this practicality is newly for adopting good heat dissipation effect and the low compound heat dissipation element of steel pipe aluminium flake expanded joint of price that technical conditions are provided.

Description of drawings:

Fig. 1 is the transversal facial canal that the radius of curvature of the semi arch at two ends and both sides is formed greater than the curve of semi arch radius, Fig. 2 is three circular arcs and 3 transversal facial canals that curve is formed, Fig. 3 is four circular arcs and four transversal facial canals that curve is formed, Fig. 4 is five circular arcs and five transversal facial canals that curve is formed, and Fig. 5 is before Fig. 1 expand tube

Shape of cross section, Fig. 6 are the shape of cross section before Fig. 2 expand tube, and Fig. 7 is the shape of cross section before Fig. 3 expand tube, and Fig. 8 is the shape of cross section before Fig. 4 expand tube, and Fig. 9 is the compound structural representation of section of jurisdiction of the present utility model expanded joint.

The specific embodiment:

Now in conjunction with above-mentioned accompanying drawing 9, the utility model is elaborated, make the steel pipe of certain-length by the shape of Fig. 5, with aluminium foil punching out fin, make the straight tube identical with Fig. 5 shape on fin, the size that the arc radius at these two ends and the width of rectangle part should be a bit larger tham Fig. 5 is advisable being enclosed within on the pipe smoothly, the height of straight tube can be according to the designing requirement manufacturing, and its size is required to determine by heat transfer and windage.To go here and there one by one on pipe 1 towards good fin 2, and it will be contained in carry out expand tube with hydraulic pressure on the expanded joint anchor clamps, because the outwards distortion easily under pressure of the straight flange of pipe.Intermediate deformation amount maximum is reduced to a curve gradually to the two ends variable vector, and the back of expanding is because two side planes of pipe become curved surface, and the girth of its cross section increases, and forces the straight tube distortion of fin on the tube surface, and forcing is that fin and pipe swelling are combined into one.Can select the tonnage of hydraulic press according to the requirement of expanded joint.Also can adopt mechanical expanding joint process, the shape of the head that expands and the identical bulk of shape of Fig. 1 are that the straight line by the rectangle both sides becomes the curve acquisition, and the arc radius at two ends does not increase, otherwise needed expanded joint power will be very big.Promptly can be made into the section of jurisdiction expanded joint compound heat dissipation element of cross section as stated above for Fig. 2, Fig. 3 and Fig. 4.

Claims
