Abstract

Several columns of the design's radiator all are double-layer ribbed tubes of same structure, and this double-layer ribbed tube is made of outer rib aluminium shaped tube and the inner rib aluminum type tube that axial line coincides, and are connected the upper and lower port of all double-layer ribbed tubes by the aluminium pipe of two parallel symmetries.Thereby simplified the manufacturing process of radiator, and made it have light and handy, comprehensive advantage such as area of dissipation big, bearing capacity does, corrosion resistance and good and lustrous surface are attractive in appearance of a tightly knit structure.

Description

Double-layer ribbed tube column-type radiator

Doing things creatively of the design is in the comprehensive improvement aspect material and the version to popular column-type radiator.

Column-type radiator is used in the heating system of civil building etc. widely.At present, the social column-type radiator that is popular in mainly contains following two kinds, and its weak point is respectively arranged:

(1) cast steel and iron formula: the wall thickness heaviness, building load is big; Mechanical strength is low, and air-tightness is poor; Working condition is abominable;

(2) plate sheet welding formula: the thin not corrosion resistant of wall, service life lack; The surface anticorrosion layer hinders heat radiation; The manufacturing process complexity exists " three wastes " to pollute.

(3) be difficult to be shaped on radiated rib on the outside wall surface of above two kinds of column-type radiators, the release of heat is subjected to the restriction of area of dissipation.

The design's guiding theory is: the aluminum alloy extrusion section bar that adopts little, the high heat conduction of proportion, corrosion-resistant, lustrous surface is as the mother metal that constitutes radiator; Structurally enlarge area of dissipation as far as possible and promote the turbulent condition of lumen of radiator fluid and the outer heating space of radiator gas to stream mode.

The column-type radiator of forming the design mainly is three kinds of aluminium section bars, that is: the double-layer ribbed tube that constitutes with outer rib aluminium shaped tube and inner rib aluminum type tube connects the upper and lower port of several columns as several columns of radiator with two parallel, symmetrical transverse tubes.The feature of its version is as described below:

(1) m of this radiator (promptly several) column all is double-layer ribbed tubes of same structure, and this double-layer ribbed tube is made up of outer ribbed pipe 1 and internally finned tube 2 that axial line coincides, forms annular vertical cavity K by the internal face of outer ribbed pipe 1 and the outside wall surface of internally finned tube 2 ₁, being shaped on some and tube wall outside on the outside wall surface of ribbed pipe 1 is the longitudinal fin J of one ₁, to be shaped on some and tube wall on the internal face of internally finned tube 2 be the longitudinal fin J of one ₂; Internally finned tube 2 is longer than outer ribbed pipe 1, and the difference of both length approximates the height sum of

transverse tube

3 and 4.

(2) upper lateral tube 3 can be the rectangular tube with little fillet, its port be shaped on screwed pipe connect 5 and (or) 6, its upper wall is shaped on m through hole H ₁, the aperture is same as the external diameter of internally finned tube 2 approximately, its lower wall also is shaped on m through hole H ₂, the aperture is same as the external diameter of external fin pipe 1, m H approximately ₁A hole and m H ₂The corresponding one by one and axial line coincidence in hole.

(3) connect for ease of the welding of above-mentioned double-layer ribbed tube and transverse tube, can be earlier except the machining car the outer fin at ribbed pipe 1 two-port place, make its two ends respectively form the external cylindrical surface E of a bit of apleuria, perhaps the two-port of ribbed pipe 1 is respectively welded a bit of pipe outside; Car remove internally finned tube 2 two-port places inner rib plate, make its two-port respectively form the inner cylinder face F of a bit of apleuria; Thereby make the upper port of m internally finned tube 2 and m H on the upper lateral tube 3 ₁The hole coincide one by one and welds, and makes the upper port of m outer ribbed pipe 1 and the H on the upper lateral tube 3 ₂The hole coincide one by one and welds; The outside wall surface of the upper end of the internal face of upper lateral tube 3 and internally finned tube 2 forms transverse passageway K ₂

(4) lower transverse tubule 4 is parallel symmetry tubes of upper lateral tube 3, its version and all identical with upper lateral tube 3 with the connecting mode of m double-layer ribbed tube column.

(5) for impelling vertically cavity K of annular ₁In fluid trend turbulent condition, being shaped on several outside on the internal face of ribbed pipe 1 is the longitudinal fin J of one with tube wall ₃, its radial height is less than toroidal cavity K ₁Radial clearance, and (perhaps) is shaped on similar J on the outside wall surface of internally finned tube 2 ₃Several longitudinal fin J of fin ₄, J ₃Fin and J ₄The fin dislocation is arranged.

The design's double-layer ribbed tube column-type radiator has following tangible advantage:

(1) form three kinds of aluminium section bars of the design's radiator, its extrusion process maturation, production efficiency are higher, and being coupled to each other of they have only a spot of circular weld, thereby have simplified the manufacturing process of radiator, have reduced production cost.

(2) with several the columns of double-layer ribbed tube as radiator, enlarged area of dissipation significantly, wherein the version of internally finned tube can significantly promote the gaseous exchange in heating space.

(3) aluminium section bar has good air-tightness; Some fins on the double-layer ribbed tube promptly are fin, are reinforced sheets again; The connecting mode of double-layer ribbed tube and two transverse tubes has also been strengthened the rigidity of transverse tube; Thereby can make the design's radiator be adapted to water, steam heating system that skyscraper and technical conditions are had relatively high expectations.

(4) the design's radiator is with the principle of " making the best use of everything ", but brought into play the aluminium section bar one-shot forming, and little, the high heat conduction of proportion, corrosion-resistant, comprehensive advantage such as lustrous surface is attractive in appearance, has better practicability.
