Description
Technical field
The present invention relates to a kind of heat-exchange tube, especially a kind of aluminum pipe external helicoid be wound around revolve fin revolve fin type heat exchanging tube.
Background technology
Heat-exchange tube, is to be mainly used in the part heat of hot fluid to pass in the equipment of cold fluid, and fluid flows through and carries out heat exchange in heat-exchange tube inside.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies aborning critical role.Parts important in heat exchanger are exactly heat-exchange tube, and the heat transfer effect of heat-exchange tube is also the important guarantee of heat exchanger performance.In Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., applies more extensive.Heat exchanger kind is a lot, but substantially can divide three major types according to the principle of cold and hot fluid exchange heat and mode: dividing wall type, hybrid and heat accumulating type.
Heat exchanger is for improving performance, can use a kind of fin type heat exchanging tube with more area of dissipation, common heat-exchange tube is all the direct spiral winding heat sink of appearance at aluminum pipe, and heat sink contacts with aluminum pipe appearance, extends by the area of heat sink the radiating effect that expands heat-exchange tube.
Such as: Patent Office of the People's Republic of China discloses a CN101363694A document on February 11st, 2009, name is called shell-pipe head exchanger by double helix flowing of fluid medium in or out of heat exchange tube, by the housing sealing by end socket, be arranged on shell side import and shell side outlet in housing sidewall, be positioned at shrouding one and the shrouding two at enclosure interior two ends, be arranged on tube side import and tube side outlet on end socket, be positioned at deflection plate and multiple heat exchanger tube composition being installed in parallel between shrouding one and shrouding two of enclosure interior, heat exchanger tube comprise outer tube and core pipe and at the two spaced winding tube core around the inner fin being embedded, deflection plate is the helical baffles that is communicated with shell side import and shell side outlet, and three forms longitudinal spiral formula shell-side circulation passage, inner fin is formed and between outer tube and core pipe, is formed a longitudinal spiral formula internally finned tube by the bending of ripple inner fin plate, and it is communicated with the interior circulation passage of composition pipe with tube side import and tube side outlet.But ripple inner fin plate is bending winding of circumferencial direction along core pipe appearance, and the inner chamber that ripple forms is closed, and can not form efficiently radiates heat, therefore can waste part area of dissipation.
Summary of the invention
The object of this invention is to provide one and revolve fin type heat exchanging tube, have at aluminum pipe appearance spiral winding the fin of revolving, the outer side edges of revolving fin is corrugated, and the inner side edge that revolves fin is straight flange, expands area of dissipation, improves radiating effect.
It is rising structure that the present invention has also solved the existing fin that revolves, and can not make full use of the defect of the area of dissipation of aluminum pipe appearance expansion, provides one to revolve fin type heat exchanging tube, and the outer side edges of revolving fin is corrugated, has expanded area of dissipation, has improved radiating effect.
The present invention has also solved the existing fin that revolves and has been wound a closed inner chamber along the periphery ripple of aluminum pipe, can not form the defect of efficiently radiates heat, provide one to revolve fin type heat exchanging tube, the outer side edges of revolving fin is corrugated, expand area of dissipation, can not form closed inner chamber, improve radiating effect.
The technical solution adopted for the present invention to solve the technical problems is: one is revolved fin type heat exchanging tube, comprise the aluminum pipe of Intermediate Gray passage, aluminum pipe external helicoid is wound with and revolves fin, revolving fin is banded structure, a side that revolves fin is straight flange, another side that revolves fin is rippled edge, and straight flange is adjacent to the appearance of aluminum pipe; Revolve the axis equidistant spiral winding of fin along aluminum pipe.Revolving fin is banded structure, and spiral winding is vertical when outside to aluminum pipe, can not form the inner chamber of sealing, ensures that the two sides of revolving fin all contact with the external world; Revolving fin one side is straight flange, and opposite side is rippled edge, and straight flange is adjacent to mutually with aluminum pipe outside, and rippled edge is in outside, and rippled edge has increased length than straight flange and also just expanded the area of dissipation that revolves fin, has improved the radiating effect of heat-exchange tube.
As preferably, revolve fin for thick structure such as grade, the width of rippled edge is 2:5-1:1 with the ratio that revolves fin self width.Rippled edge, as the outer side edges of revolving fin winding, is convenient to revolve fin and is wound around, because the girth of the periphery of spiral winding is greater than the girth in the interior week of spiral winding, rippled edge can make the periphery of revolving fin produce prolongation, the outer side edges of revolving fin self can not torn.
A kind of structure of rippled edge is: rippled edge is the connected single wave structures that form of multiple crests, between crest and crest, is connected by straight section.This structure is convenient to processing, and rippled edge is all heaved formation crest towards a side.
The another kind of structure of rippled edge is: rippled edge is the structure that crest is connected and forms with trough.This structure more can expand the area of dissipation that revolves fin.
As preferably, the width of rippled edge with revolve fin width while equating, the bending intermediate location of rippled edge is radial according to the axis of aluminum pipe.When the width of rippled edge equals to revolve the overall with of fin, the bending intermediate location of rippled edge extends to another side from a side that revolves fin, and bending intermediate location is radial arrangement conveniently revolves the spiral winding of fin.
As preferably, the crest height of wave of rippled edge be revolve fin thickness 1-5 doubly.
As preferably, revolve fin spiral winding behind aluminum pipe outside, the spacing between straight flange is 3-20mm.
As preferably, aluminum pipe inside is provided with single channel, and aluminum pipe inwall is light wall or the internal tooth wall with rake tooth.This structure, logical single fluid in aluminum pipe; Internal tooth wall can increase the contact area of fluid and aluminum pipe inwall, improves radiating effect.
As preferably, aluminum pipe inside is provided with multichannel, between passage and passage, separates by conduit wall.Multichannel can lead to obstructed fluid, if connect the parts of a backflow in heat-exchange tube end, just can in passage, lead to the fluid of circulation, is applicable in the situation of streaming flow small volume.
As preferably, the conduit wall in aluminum pipe is cross, and aluminum pipe interior separation is become four passages by cross conduit wall; Or the axis place of aluminum pipe arranges an internal channel, between internal channel wall and aluminum pipe wall, separate and be connected by muscle, the gap between internal channel wall and aluminum pipe wall is separated into multiple outer tunnels by muscle.
The invention has the beneficial effects as follows: revolving fin one side is straight flange, and opposite side is rippled edge, and straight flange is adjacent to mutually with aluminum pipe outside, and rippled edge, in outside, has expanded the area of dissipation that revolves fin, has improved the radiating effect of heat-exchange tube; Revolving fin is the banded inner chamber that can not form sealing, ensures that the two sides of revolving fin all contact with the external world.
