Abstract
The utility model discloses a degree of depth helicla flute trades heat pipe exchanger, its characterized in that: it is degree of depth helicla flute heat exchange tube (11) that the heat exchanger includes the inside heat exchange tube that adopts, degree of depth helicla flute heat exchange tube (11) includes outer tube (2) and interior sleeve pipe (3), all be provided with the entry and the export of medium on outer tube (2) and interior sleeve pipe (3). The utility model discloses heat exchange efficiency has not only been improved, big buret material can be saved moreover.
Description
Technical field
The utility model relates to field of heat exchangers, is specially a kind of deep spiral groove hot pipe heat exchanger.
Background technology
Dividing wall type heat exchanger be always continue to use various material light pipe as heat exchange element, in order to improve heat exchange efficiency, often be rolled into helicla flute or coiling fin etc. at light pipe surface, but be no more than 3mm because a rolling helicla flute degree of depth 1-2mm is maximum, and finned tube is still machine glazing wall, so effect is all undesirable.
Utility model content
The utility model is for above weak point, and provide a kind of deep spiral groove hot pipe heat exchanger, the utility model not only increases heat exchange efficiency, and can save a large amount of tubing.
The utility model solves the technical scheme that its technical problem adopts: a kind of deep spiral groove hot pipe heat exchanger, the heat exchanger tube that described heat exchanger inside adopts is deep spiral groove heat exchanger tube, described deep spiral groove heat exchanger tube includes outer tube and inner sleeve, described outer tube and inner sleeve is provided with the entrance and exit of medium.
The pitch of described deep spiral heat exchanger tube inner sleeve and outer tube is set to 0.2-1.5 caliber doubly, and described groove depth is set to 0.1-0.25 times of caliber.
The pitch of described outer tube is greater than the pitch of inner sleeve.
Described heat exchanger also includes housing, up and down header, medium I entrance, medium I outlet, medium II entrance, medium II and exports, described enclosure interior is provided with the heat-exchanging component be made up of deep spiral groove heat exchanger tube, in described heat-exchanging component, the medium inlet of outer tube connects upper header, upper header stretches out hull outside and is provided with medium I entrance, the media outlet of described outer tube connects lower collecting box, and lower collecting box stretches out hull outside and is provided with media outlet; The medium inlet of described inner sleeve is connected in the medium II entrance of case top by pipeline, the medium II that the media outlet of described inner sleeve is connected in housing bottom by pipeline exports, and except the cavity of heat-exchanging component, respectively connecting media II entrance and medium II export described enclosure interior.
Described outer tube is different with institute's injected media in inner sleeve, and described inner sleeve is identical with institute's injected media in cavity.
Heat exchange element is combined into by upper and lower header tube, and heat exchanger tube can be made to save heaviness, expensive tube sheet, and heat exchange is thought highly of and alleviates, price reduces;
Because light pipe wall is pressed to form deep spiral groove, tube surface is amassed and adds about 20%, not only can improve the thermal efficiency, and can a large amount of tubing be saved;
The inner sleeve of heat exchange element and outer tube are rolled into deep spiral groove, effectively change the flow regime of medium, and heat exchange efficiency is increased substantially;
Heat exchange element is relatively independent, effectively overcomes the thermal stress impact of heat exchanger tube, add the service life of heat exchanger, and independently heat exchange element is convenient to the maintenance of heat exchanger;
The heat exchanger volume formed is less, and weight is lighter.
Accompanying drawing explanation
It is structural representation of the present utility model shown in Fig. 1;
It is the structural scheme of mechanism of the utility model deep spiral groove hot pipe heat exchanger shown in Fig. 2;
It is profile of the present utility model shown in Fig. 3.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown be a specific embodiment of the present utility model, a kind of deep spiral groove hot pipe heat exchanger, described heat exchanger includes housing 12, upper and lower header 9, 10, medium I entrance 5, medium I exports 6, medium II entrance 7, medium II exports 8, described housing 12 inside is provided with the heat-exchanging component be made up of deep spiral groove heat exchanger tube 11, it is deep spiral groove heat exchanger tube 11 that described heat exchanger includes the inner heat exchanger tube adopted, described deep spiral groove heat exchanger tube 11 includes outer tube 2 and inner sleeve 3, described outer tube 2 and inner sleeve 3 are provided with the entrance and exit of medium, in described heat-exchanging component, the medium inlet of outer tube 2 connects upper header 9, upper header 9 stretches out housing 12 outside and is provided with medium I entrance 5, the media outlet of described outer tube 2 connects lower collecting box 10, upper header 10 stretches out housing 12 outside and is provided with media outlet 6, the medium inlet of described inner sleeve 3 is connected in the medium II entrance 7 at housing 12 top by pipeline, the medium II that the media outlet of described inner sleeve 3 is connected in bottom housing 12 by pipeline exports 8, and described housing 12 inside is except cavity connecting media II entrance 7 and the medium II outlet 8 respectively of heat exchanger assembly.
The pitch of described deep spiral heat exchanger tube inner sleeve 3 and outer tube 2 is set to 0.2-1.5 caliber doubly, and described groove depth is set to 0.1-0.25 times of caliber.
The pitch of described outer tube 2 is greater than the pitch of inner sleeve 3.
Described outer tube 2 is different with institute's injected media in inner sleeve 3, and described inner sleeve 3 is identical with institute's injected media in cavity.
Heat exchange element is combined by the deep spiral barrel that inside and outside two rotation directions are different, after in, outer tube outer at inner sleeve, interval medium enters, under the effect of bidirectional screw, local is cut to two-layer, respectively along different rotation directions moving from top to bottom, in medium motion process, fluid hands over mixed motion with eddy flow, turbulent flow pattern, Re coefficient is improved greatly, effectively raises the exchange capability of heat of heat exchanger.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
