The invention discloses a twisted tooth finned tube and a finned tube heat exchange tube bundle. The twisted tooth finned tube provided by the invention comprises a base tube part and a fin part, wherein the fin part comprises a substrate which is fixedly arranged on the outer wall along a preset path and is continuously formed, a plurality of twisted teeth which are connected to the substrate and outwards extend along the radial direction of a base tube, and a plurality of opening slots which are formed between every two adjacent twisted teeth along the direction of the preset path; the bottom ends of the twisted teeth are integrally connected with the substrate; the top ends of the twisted teeth are twisted by certain angles relative to the bottom ends of the twisted teeth. With the structure of the fin part, the finning ratio of the finned tube is greatly increased, and the manufacturing difficulty of the finned tube is reduced; moreover, the top ends of the twisted teeth are twisted by certain angles relative to the bottom ends of the twisted teeth, so that the disturbance and heat exchange of fins to air flow outside the tube are greatly enhanced; therefore the twisted tooth finned tube is excellent in enhanced heat exchange performance.
Description
Technical field
The present invention relates to a kind of finned tube, be specifically related to one and turn round tooth finned tube and finned tube heat-exchanging tube bundle thereof.
Background technology
Install the ring-shaped finned tube that ring fin is made in engineering heat-exchanger rig outside extensive use pipe additional, common ring-shaped finned tube comprises spiral fin coil and suit finned tube.Spiral fin coil is entwined at base tube perficial helical by strip metal fin, and suit finned tube is arranged by each disjunct ring fin at a certain distance along tube axial direction and is set with base tube and is formed by connecting.Spiral fin coil and suit finned tube easily manufactured and wingization is larger, obviously can reduce and manage outer air-flow side heat exchange thermal resistance, therefore be widely used in all kinds of air-flow heat-exchanger rig.Press finned tube enhanced heat exchange general principle, improve heat exchange tube fin ratio and can reduce pipe outer air-flow side thermal resistance, thus make the metal consumption of heat-exchanging tube bundle less, volume is compacter.Improve ring-shaped finned tube wingization to realize than by reducing spacing of fin and raising fin height two kinds of approach.But the reduction of spacing of fin is subject to managing the restriction of outer air-flow containing grey dust-laden situation, too small spacing of fin can make finned tube seriously stifled grey at work.Meanwhile, the raising of fin height is subject to the restriction of fin metal ductility, especially for steel fin, crooked or tear for ensureing that fin top does not occur when manufacturing finned tube, has to select very low fin height, and corresponding lower heat exchange tube fin ratio.
Prior art discloses a kind of serrated helicoid finned tube, fin is carried out partial cut tooth punching by according to a determining deviation before carrying out spiral winding to base tube, fin is when carrying out spiral winding to base tube, cut part separately forms v-notch, this configuration eliminates original fin end portion by the excessive impact on fin quality of metal strain amount, compared with the spiral fin coil of sequential like, this technical scheme can ensure that fin takes higher fin height under indeformable prerequisite of not tearing, thus increases substantially the wing ratio of spiral fin coil.
Although above-mentioned serrated helicoid finned tube increases the wing ratio of spiral fin coil, but, due to wherein sawtooth be plain fin and the trend of sawtooth and fin spiral winding move towards substantially parallel, therefore, under identical fin tube structure and tube bank arrangement, " heat exchange amount/fluid transport power consumption " comprehensive heat exchange property of serrated helicoid finned-tube bundle is bordering on identical with continuous helical finned-tube bundle.This is mainly because the perturbation action of sawtooth to the outer air-flow of base tube is faint, caused by thus poor to the strengthening effect of fin surface exchange capability of heat.When therefore comparing under identical finned tube metal consumption, the enhanced heat exchange effect of this serrated helicoid finned tube is very limited.
Summary of the invention
The present invention carries out to solve the problem, object be to provide a kind of to the outer air-flow of base tube can effective disturbance enhanced heat exchange turn round tooth finned tube and finned tube heat-exchanging tube bundle thereof, thus realize finned tube be easy to manufacture and wingization than on larger basis, improve finned tube " heat exchange amount/fluid transport power consumption " comprehensively heat exchange property further.
