Description
Technical field
The utility model belongs to technical field of heat exchangers, is specifically related to a kind of plate-fin heat exchanger punching corrugated fin structure.
Background technology
Plate-fin heat exchanger is a kind of common high-performance heat exchanger, is widely used in oil, chemical field, particularly as cryogenic heat exchanger, is applied to air separation and Liquefaction Industry, has compact conformation, heat exchange efficiency advantages of higher.What plate-fin heat exchanger fin was at present most widely used mainly contains four kinds, respectively plain fin, saw tooth fin, corrugated fin, perforated fin, louvered fin, it has different heat transfer characteristics different fins, the differential pressure resistance of plain fin heat transfer effect is minimum, but install to clean and wait facility the most, serrated fin heat transfer effect is best, but pressure drag is also maximum, corrugated fin is particularly suitable for the fluid that viscosity is larger, perforated fin is perforate gained on the basis of plain fin, is used in the heat exchange environment of phase transition process.Generally can be used for flow deflector and be beneficial to being uniformly distributed of fluid, and common corrugated fin and perforated fin be due to its limited heat exchange area and turbulence effect, heat transfer effect is poor.
Utility model content
The defect existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of plate-fin heat exchanger punching corrugated fin structure that is applicable to the fluid that viscosity is larger or has the fluid of phase-change heat-exchange, this structure has reduction flow resistance, prevents from stopping up and improving the effect of heat exchange efficiency.
The utility model is to be achieved through the following technical solutions:
A kind of plate-fin heat exchanger punching corrugated fin structure, comprise the corrugated fin that some even parallel interval are arranged, angle on each corrugated fin between adjacent two ripples is 100 °～150 °, on each corrugated fin, all offer some through holes, on each corrugated fin, the percent opening of through hole is 5%～10%.
Described through hole is opened in top or the middle part of corrugated fin.
Angle on described each corrugated fin between adjacent two ripples is 120 °.
On described each corrugated fin, the percent opening of through hole is 7%.
Described corrugated fin adopts one time punching molded.
Described corrugated fin is made by aluminium sheet or a punching press of steel plate.
Compared with prior art, the utlity model has following useful technique effect:
Plate-fin heat exchanger punching corrugated fin structure of the present utility model comprises the corrugated fin that some even parallel interval are arranged, and on corrugated fin, offers some through holes.When fluid is flowed through corrugated fin, can form by nip with to nip in the both sides of fin, by the fluid of nip, flowed and be slowly not easy to the carrying out of heat exchange, and after the perforate of the appropriate location of corrugated fin, fluid is flowed through, and hole is neighbouring can form vortex, make fin fluid around become disorderly, enhanced flow dynamic resistance, and flowing of fluid is also no longer confined in a passage, two side liquids of same fin can form horizontal mixing, reach the object of strengthening heat exchange, especially in the plate-fin heat exchanger that has phase transformation to produce, the less gas phase of density that phase transformation produces can in flow process, constantly be gathered in runner above, the perforate of diverse location is conducive to the exchange of different runner inner fluids, thereby it is more even that fluid is distributed, further strengthened heat exchange.The plate-fin heat exchanger punching corrugated fin structural flow general character of the present utility model is good, is specially adapted to the fluid that viscosity is larger or has in the fluid of phase-change heat-exchange, has reduction flow resistance, prevents the effect of obstruction, can effectively improve the heat exchange property of heat exchanger.
