Abstract
The utility model discloses a chevron shape trompil corrugated fin type finned plate heat exchanger. Its technical scheme is: including corrugated fin, through -hole, baffle, corrugated fin set up between upper and lower two baffles through brazing, seted up a plurality of through -holes on every corrugated fin, chevron shape for having inclination between every corrugated fin. The beneficial effects are that: finned plate heat exchanger has not only increased heat transfer area but also has strengthened the vortex, and then has increased heat transfer performance, and the trompil can destroy mobile boundary layer effectively, promotes the effect of the horizontal intensive mixing of fluid in order to play enhanced heat transfer, can effectively improve heat transfer performance with through -hole staggered arrangement, set up the chevron shape range for the inclination 80 who has best heat transmission effect with corrugated fin, further improved heat transfer efficiency especially, in addition, ripple cycle of corrugated fin is set up when the 3mm that it has better mechanical properties, bearing strength can be strengthened.
Description
Technical field
This utility model belongs to technical field of heat exchangers, is specifically related to a kind of herringbone perforate corrugated-fin type plate-fin heat exchanger.
Background technology
Plate-fin heat exchanger is that a kind of heat transfer efficiency is high, the most firm, adaptability big, the compact heat exchanger of good economy performance, it is widely used in multiple fields such as oil, vehicle, aviation, chemical industry, refrigeration system, atomic energy, so one of being considered the most rising Novel hot switching equipment.The basic structure of plate-fin heat exchanger is that wherein fin assume responsibility for main transfer duty and main pressure-bearing task by dividing plate, strip of paper used for sealing, fin and flow deflector composition.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that a kind of herringbone perforate corrugated-fin type plate-fin heat exchanger, this herringbone perforate corrugated fin had both improve heat exchange efficiency, and enhanced again bearing strength.
Its technical scheme is: include corrugated fin, through hole, dividing plate, and described corrugated fin is arranged between upper and lower two dividing plates by soldering, offers multiple through hole on each corrugated fin, and the cross section of fin is herringbone structure；Described through hole is opened at the crest of corrugated fin, and through hole is staggered, and the angle of inclination of described corrugated fin is 80 °.
The wavelength of above-mentioned corrugated fin bellows-shaped is 1.5mm, and crest is 0.25mm.
The beneficial effects of the utility model are: plate-fin heat exchanger not only adds heat transfer area but also strengthens flow-disturbing, and then add heat transfer property, and perforate can destroy flow boundary layer effectively, promoting that fluid is laterally sufficiently mixed to play the effect of augmentation of heat transfer, being staggered by through hole to be effectively improved heat transfer property；Corrugated fin is set to the circular array with 80 ° of the angle of inclination of best heat-transfer effect, further increases heat transfer efficiency especially；Further, when the corrugated periodic of corrugated fin being arranged on 3mm, it has preferable mechanical property, it is possible to strengthen bearing strength.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is left view of the present utility model；
Accompanying drawing 3 is front view of the present utility model；
In upper figure: corrugated fin 1, through hole 2, dividing plate 3.
Detailed description of the invention
In conjunction with accompanying drawing 1-3, the utility model will be further described:
This utility model includes corrugated fin 1, through hole 2, dividing plate 3, described corrugated fin 1 is arranged between upper and lower two dividing plates 3 by soldering, offering multiple through hole 2 on each corrugated fin 1, the cross section of fin is the herringbone structure with angle of inclination, and is arranged in order.
Wherein, through hole 2 is opened at the crest of corrugated fin 1, and through hole 2 is staggered.
It addition, the angle of inclination of corrugated fin 1 is 80 °.
Further, the wavelength of corrugated fin 1 bellows-shaped is 1.5mm, and crest is 0.25mm.
Herringbone wavy fin and perforate fin can improve heat exchange efficiency, and corrugated fin can improve heat exchange efficiency can improve again the bearing strength of heat exchanger.By designing the angle of inclination with herringbone wavy fin feature of this herringbone corrugated fin, the corrugated periodic of corrugated fin feature, crest size, the perforate size and location of perforate fin feature, have obtained a kind of Novel fin substantially increasing heat transfer efficiency and bearing strength.On corrugated fin, perforate destroys flow boundary layer effectively, promotes that fluid is laterally sufficiently mixed, serves the effect of augmentation of heat transfer；The fin with angle of inclination can be greatly improved heat transfer efficiency, and in the corrugated fin that inclination angle is 75 degree of-90 degree, inclination angle is that the corrugated fin of 80 degree has best heat-transfer effect；Compared to Bo Yaochu, going out perforate heat transfer property at crest and improve 5%-8%, stagger arrangement aperture arranges that the heat transfer property of correspondence arranges corresponding heat transfer property, maximum raising about 14% higher than parallel aperture；Owing to corrugated periodic size is little on the impact of heat-transfer effect, and corrugated periodic is in 1mm-4mm, and when corrugated periodic is 3mm, it has preferable mechanical property, and its Elastic Modulus improves about 3.7%, and yield strength improves about 4.6%.Sum it up, compared to traditional corrugated fin, this herringbone corrugated fin improves heat exchange efficiency, enhances bearing strength.
This utility model plate-fin heat exchanger not only adds heat transfer area but also strengthens flow-disturbing, and then add heat transfer property, and perforate can destroy flow boundary layer effectively, promoting that fluid is laterally sufficiently mixed to play the effect of augmentation of heat transfer, being staggered by through hole to be effectively improved heat transfer property；Corrugated fin is set to the circular array with 80 ° of the angle of inclination of best heat-transfer effect, further increases heat transfer efficiency especially；Further, when the corrugated periodic of corrugated fin being arranged on 3mm, it has preferable mechanical property, it is possible to strengthen bearing strength.
The above, be only preferred embodiment of the present utility model, and this utility model is all revised possibly also with the technical scheme of above-mentioned elaboration or is revised as the technical scheme of equivalent by any those of ordinary skill in the art.Therefore, any simple modification carried out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that this utility model is claimed.
