Abstract
The utility model discloses a kind of change spacing of fin formula plate-fin heat exchanger.This utility model includes inlet tube and outlet, described inlet tube is sequentially connected with the first flow deflector, the first fin section, mixing chamber the one, second fin section, mixing chamber the two, the 3rd fin section, the second flow deflector and outlet, described first fin section, the second fin section, the 3rd fin section length identical, spacing between the fin of each fin section is successively decreased successively, the spacing of fin of the first fin section is maximum, and the spacing of fin of the 3rd fin section is minimum.Fluid after entrance heat exchanger is after initial fin section carries out heat exchange, and heat exchange efficiency reduces, and heat flow density declines.The mixed fluid of mixing chamber through centre position, after being again introduced into the fin section that spacing of fin is shorter, heat exchange efficiency will significantly improve.
Description
Technical field
This utility model relates to field of heat exchangers, in particular, is a kind of change spacing of fin formula plate-fin heat exchanger.
Background technology
Plate-fin heat exchanger is high because of its heat transfer efficiency, and the advantages such as temperature control is good, compact conformation receive publicity.The most again
Because it is lightweight, good economy performance is applied to the every field in society, such as, be applicable to oxygen processed, ethylene and helium liquefaction etc. deep
Cryogenic equipment, power set etc..But plate-fin heat exchanger internal heat is the most uneven, have a strong impact on sending out of plate-fin heat exchanger
Exhibition.
Utility model content
This utility model is the technological improvement carried out on the basis of conventional panels fin heat exchanger, makes plate-fin heat exchanger exist
During heat exchange, fin section can fully adapt to the change of fluid temperature (F.T.).Three sections of fin sections that spacing of fin is successively decreased are set, reduce by hot-fluid
Density reduces the heat exchange caused and slackens, and strengthens heat exchange.
This utility model be the technical scheme is that
A kind of becoming spacing of fin formula plate-fin heat exchanger, including inlet tube and outlet, described inlet tube is sequentially connected with the
One flow deflector, the first fin section, mixing chamber the one, second fin section, mixing chamber the two, the 3rd fin section, the second flow deflector and outlet
Pipe, described first fin section, the second fin section, the 3rd fin section length identical, spacing between the fin of each fin section
Successively decreasing successively, the spacing of fin of the first fin section is maximum, and the spacing of fin of the 3rd fin section is minimum.
Compared with general plate-fin heat exchanger, become spacing of fin formula plate-fin heat exchanger and have the advantages that
1, while this utility model plate-fin heat exchanger length needed for keeping, the change of spacing of fin decreases stream
Dynamic resistance, improves economy.
2, in this utility model, fluid is after one section of heat transfer process, and fluid thermal current density declines, the wing successively decreased successively
Sheet certain distance is also for adapting to this operating mode, and heat transfer effect is improved.
This utility model, for reinforcing plate fin heat exchanger heat exchange efficiency, reduces along plate-fin heat exchanger fluid flow inside
The problem that direction fluid heat transfer is gradually reduced, is divided into plate-fin heat exchanger suitable three section, arranges mixing chamber between every section,
Fluid will mix at mixing chamber, then enter next fin section and carry out heat exchange.The fin section that spacing diminishes can be more preferable
Play fin section heat exchange effect.
Accompanying drawing explanation
Fig. 1 show this utility model and becomes the schematic diagram of spacing of fin formula plate-fin heat exchanger.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is become spacing of fin formula plate-fin heat exchanger to be described in further detail.
This utility model becomes spacing of fin formula plate-fin heat exchanger, by arranging between the fin section of plate-fin heat exchanger
Mixing chamber, fin certain distance is sequentially reduced, and can strengthen the heat exchange efficiency of this change spacing of fin formula plate-fin heat exchanger.Such as Fig. 1 institute
Show, including inlet tube 1 and outlet 9, described inlet tube be sequentially connected with first flow deflector the 2, first fin section 3, mixing chamber 1,
Second fin section 5, mixing chamber the 26, the 3rd fin section the 7, second flow deflector 8 and outlet 9, described first fin section, the second wing
Fragment, the 3rd fin section length identical, the spacing between the fin of each fin section is successively decreased successively, the fin of the first fin section
Spacing is maximum, and the spacing of fin of the 3rd fin section is minimum.
Fluid first passes through inlet tube 1 and enters flow deflector 2, carries out heat exchange hence into the first fin section 3.After heat exchange
Entering mixing chamber 1 and carry out the mixing of fluid, the second fin section 5 that the fluid of uniform distribution is again introduced into spacing shorter is carried out again
Secondary heat transfer process.Enter back into mixing chamber 26 and the shortest the 3rd fin section 7 of spacing, enter outlet finally by flow deflector 8
9, complete the whole heat transfer process of whole plate-fin heat exchanger.Mixing chamber at one is set after each fin section, makes fluid abundant
Mixing after flow into next fin section.Fluid passes through three fin sections and therebetween mixing chamber, and fin certain distance is successively
Narrow, thus adapt to the fluid thermal current density reduced.Flow into outlet finally by flow deflector, terminate whole heat transfer process.
The above is only the advantageous applications content of this utility model patent, for the relevant working technology people in this area
For Yuan, on the premise of without departing from this utility model patent principle, everybody can also supplement accordingly and revise, but institute
The amendment and the application that carry out should be within the protection domains of this utility model patent.
