Description
Technical field
The present invention relates to a kind of heat-exchange tube, especially a kind of the aluminum pipe external helicoid twine revolve fin revolve the fin type heat exchanging tube.
Background technology
Heat-exchange tube mainly is that fluid flows through in heat-exchange tube inside and carries out heat exchange in the equipment that is used in the part heat transferred cold fluid of hot fluid.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies aborning critical role.Important in a heat exchanger parts are exactly heat-exchange tube, and the heat transfer effect of heat-exchange tube also is the important guarantee of heat exchanger performance.Heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc. in Chemical Manufacture, uses more extensive.The heat exchanger kind is a lot, but basically can divide three major types namely according to principle and the mode of cold and hot fluid exchange heat: 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 all is that heat sink contacts with the aluminum pipe appearance at the direct spiral winding heat sink of the appearance of aluminum pipe, extends the radiating effect of expansion heat-exchange tube by the area of heat sink.
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 by the end socket sealing, be arranged on shell side import and shell side outlet on the 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 the end socket, the deflection plate and a plurality of heat exchanger tube that is installed in parallel in two of shrouding one and shroudings that are positioned at enclosure interior form, heat exchanger tube comprise outer tube and core pipe and at the two spaced winding tube core around the inner fin that is embedded; Deflection plate is for being communicated with the helical baffles of shell side import and shell side outlet, and the three forms longitudinal spiral formula shell-side circulation passage; Inner fin is formed by the bending of ripple inner fin plate and form a longitudinal spiral formula internally finned tube between outer tube and core pipe, and it is communicated with tube side import and tube side outlet and forms circulation passage in the pipe.But ripple inner fin plate is crooked 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 the part area of dissipation.
Summary of the invention
The purpose of this invention is to provide a kind of fin type heat exchanging tube that revolves, at aluminum pipe appearance spiral winding the fin of revolving is arranged, the outer side edges of revolving fin is corrugated, and the inner side edge that revolves fin is straight flange, enlarges 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 take full advantage of the defective of the area of dissipation of aluminum pipe appearance expansion, and a kind of fin type heat exchanging tube that revolves is provided, and the outer side edges of revolving fin is corrugated, has enlarged area of dissipation, has improved radiating effect.
The present invention has also solved the existing fin that revolves along closed inner chamber of periphery ripple winding formation of aluminum pipe, can not form the defective of efficiently radiates heat, a kind of fin type heat exchanging tube that revolves is provided, the outer side edges of revolving fin is corrugated, expanded 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: a kind of fin type heat exchanging tube that revolves, the aluminum pipe that comprises the Intermediate Gray passage, the 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 fin along the equidistant spiral winding of the axis of 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, guarantees 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 the aluminum pipe outside, and rippled edge is in the outside, and rippled edge has increased length than straight flange and also just enlarged the area of dissipation that revolves fin, has improved the radiating effect of heat-exchange tube.
As preferably, revolve fin and be the 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 is convenient to revolve fin and is twined as the outer side edges of revolving fin and twining, because the girth of the periphery of spiral winding is greater than the girth in the interior week of spiral winding, the rippled edge energy can not torn the outer side edges of revolving fin self so that revolve the periphery of fin and produce and prolong.
A kind of structure of rippled edge is: rippled edge is single wave structures that a plurality of crests link to each other and to form, and links to each other by straight section between crest and the crest.This structure is convenient to processing, and rippled edge is all heaved the formation crest towards a side.
The another kind of structure of rippled edge is: rippled edge is the structure that crest links to each other and forms with trough.This structure more can enlarge the area of dissipation that revolves fin.
As preferably, the width of rippled edge with revolve fin width when equating, the bending intermediate location of rippled edge is radial according to the axis of aluminum pipe.When the width of rippled edge equaled to revolve the overall with of fin, the bending intermediate location of rippled edge extended to another side from a side that revolves fin, and the bending intermediate location is the spiral winding that radial arrangement is conveniently revolved fin.
As preferably, the crest height of wave of rippled edge be revolve fin thickness 1-5 doubly.
As preferably, revolve the fin spiral winding behind the aluminum pipe outside, the spacing between the straight flange is 3-20mm.
As preferably, aluminum pipe inside is provided with single channel, and the aluminum pipe inwall is light wall or with the internal tooth wall of rake tooth.Logical single fluid in this structure, 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, separates by conduit wall between passage and the passage.Multichannel can lead to obstructed fluid, if connect the parts of a backflow in the heat-exchange tube end, just can lead to the fluid of circulation in passage, is fit in the situation of streaming flow small volume.
As preferably, the conduit wall in the aluminum pipe is cross, and the cross conduit wall becomes four passages with the aluminum pipe interior separation; Perhaps the axis place of aluminum pipe arranges an internal channel, separates between internal channel wall and the aluminum pipe wall and links to each other by muscle, and muscle is separated into a plurality of outer tunnels with the slit between internal channel wall and the aluminum pipe wall.
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 the aluminum pipe outside, and rippled edge is in the outside, has enlarged the area of dissipation that revolves fin, has improved the radiating effect of heat-exchange tube; Revolve fin and be the banded inner chamber that can not form sealing, guarantee that the two sides of revolving fin all contact with the external world.
