Abstract
The invention discloses a deep spiral groove heat exchange pipe heat exchanger. The deep spiral groove heat exchange pipe heat exchanger is characterized by comprising a deep spiral groove heat exchange pipe (11) adopted inside, the deep spiral groove heat exchange pipe (11) comprises an outer sleeve (2) and an inner sleeve (3), and a medium inlet and a medium outlet are formed in the outer sleeve (2) and the inner sleeve (3). The heat exchange efficiency is improved, and a large number of pipes can be saved.
Description
Technical field
The present invention relates to field of heat exchangers, specially a kind of deep spiral groove hot pipe heat exchanger.
Background technology
Dividing wall type heat exchanger be always the light pipe for continuing to use various materials as heat exchange element, it is past in order to improve heat exchange efficiency
Helicla flute or coiling fin etc. are rolled into toward in light pipe surface, but 3mm are no more than because rolling spiral groove depth 1-2mm is maximum,
And finned tube is still machine glazing wall, so effect is undesirable.
The content of the invention
The present invention is directed to above weak point, there is provided a kind of deep spiral groove hot pipe heat exchanger, and the present invention is not only carried
Heat exchange efficiency high, and a large amount of tubing can be saved.
The technical solution adopted for the present invention to solve the technical problems is：A kind of deep spiral groove hot pipe heat exchanger, institute
State heat exchanger to include the internal heat exchanger tube for using is deep spiral groove heat exchanger tube, and the deep spiral groove heat exchanger tube includes outer
Sleeve pipe and inner sleeve, are provided with the entrance and exit of medium on the outer tube and inner sleeve.
The pitch of the deep spiral heat exchange inner casing tube and outer tube is set to 0.2-1.5 times of caliber, the groove depth
It is set to 0.1-0.25 times of caliber.
Pitch of the pitch of the outer tube more than inner sleeve.
The heat exchanger also includes housing, upper and lower header, medium I entrances, medium I outlets, medium II entrances, medium II
Outlet, the enclosure interior be provided with by deep spiral groove set of heat exchange tubes into heat-exchanging component, outer tube in the heat-exchanging component
Medium inlet connection upper header, upper header stretches out hull outside and is provided with medium I entrances, the media outlet of the outer tube
Connection lower collecting box, upper header stretches out hull outside and is provided with media outlet；The medium inlet of the inner sleeve is connected by pipeline
The medium II entrances for being arranged at case top are connect, the media outlet of the inner sleeve is connected in housing bottom by pipeline
Medium II is exported, and the enclosure interior is except cavity connection connection medium II entrances and the medium II outlets respectively of heat exchanger assembly.
The outer tube is different with institute's injected media in inner sleeve, and the 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 heavy, expensive tube sheet, makes to change
Heat thinks highly of mitigation, price reduction；
Because light tube wall is pressed to form deep spiral groove, accumulate tube surface and increased 20% or so, can not only improve thermal effect
Rate, and a large amount of tubing can be saved；
The inner sleeve and outer tube of heat exchange element are rolled into deep spiral groove, effectively change the flow regime of medium,
Increase substantially heat exchange efficiency；
Heat exchange element is relatively independent, effectively overcomes the thermal stress influence of heat exchanger tube, increased the use longevity of heat exchanger
Life, and independent heat exchange element is easy to the maintenance of heat exchanger；
The heat exchanger volume for being constituted is smaller, and weight is lighter.
Brief description of the drawings
It is structural representation of the invention shown in Fig. 1；
It is the structural scheme of mechanism of deep spiral groove hot pipe heat exchanger of the present invention shown in Fig. 2；
It is profile of the invention shown in Fig. 3.
Specific embodiment
The present invention will be described in detail with specific embodiment below in conjunction with the accompanying drawings：
It as shown is a specific embodiment of the invention, a kind of deep spiral groove hot pipe heat exchanger, the heat exchange
Device includes housing 12, upper and lower header 9,10, medium I entrances 5, medium I outlet 6, medium II entrances 7, medium II outlet 8, institute
State housing 12 and be internally provided with the heat-exchanging component being made up of deep spiral groove heat exchanger tube 11, the heat exchanger includes internal use
Heat exchanger tube be deep spiral groove heat exchanger tube 11, the deep spiral groove heat exchanger tube 11 includes outer tube 2 and inner sleeve 3, institute
The entrance and exit that medium is provided with outer tube 2 and inner sleeve 3 is stated, the medium inlet of outer tube 2 in the heat-exchanging component
Connection upper header 9, upper header 9 stretches out the outside of housing 12 and is provided with medium I entrances 5, the media outlet connection of the outer tube 2
Lower collecting box 10, upper header 10 stretches out the outside of housing 12 and is provided with media outlet 6；The medium inlet of the inner sleeve 3 is by pipe
Road is connected in the medium II entrances 7 at the top of housing 12, and the media outlet of the inner sleeve 3 is connected in shell by pipeline
The medium II outlets 8 of the bottom of body 12, the inside of the housing 12 connects medium II entrances 7 respectively except the cavity connection of heat exchanger assembly
With medium II outlets 8.
The pitch of the deep spiral heat exchange inner casing tube 3 and outer tube 2 is set to 0.2-1.5 times of caliber, the groove
It is set to 0.1-0.25 times of caliber deeply.
Pitch of the pitch of the outer tube 2 more than inner sleeve 3.
The outer tube 2 is different with institute's injected media in inner sleeve 3, the inner sleeve 3 and institute's injected media phase in cavity
Together.
Heat exchange element is combined by the different deep spiral barrel of inside and outside two rotation directions, outside inner sleeve, in outer tube
After interval medium enters, in the presence of bidirectional screw, two-layer is locally cut to, respectively the fortune along different rotation directions from top to bottom
Dynamic, during medium motion, fluid hands over mixed motion with eddy flow, turbulent flow pattern, greatly improves Re coefficients, effectively raises and changes
The exchange capability of heat of hot device.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
Change, remodeling, addition or replacement that the technical staff in domain is made in essential scope of the invention, should also belong to of the invention
Protection domain.
