Abstract
The invention discloses a novel efficient plate-fin heat exchanger fin which comprises staggered corrugated fin bodies. The staggered corrugated fin bodies are staggered at intervals at the length end of each unit wave. An opening is formed in the middle of each unit wave, so that each unit wave is evenly divided into two halves. The novel efficient plate-fin heat exchanger fin has the advantages of staggered fins and corrugated fins at the same time, the fin bodies are staggered at the position of the length of each unit wave, and the opening is formed in the position of the length of each half unit wave, so that flowing complexity degree is increased to a great extent, a heat exchange boundary layer is effectively damaged, and the heat exchange performance of a heat exchanger is greatly improved.
Description
Technical field
The present invention relates to the technical field of heat exchanger, be specifically related to a kind of fin structure of heat exchanger.
Background technology
Plate-fin heat exchanger is considered to one of the most rising Novel hot switching equipment because of its compact conformation, the feature that light and handy, heat transfer efficiency is high, along with the raising of non-ferrous metal and stainless steel preservative treatment technology and soldering processes technology, in the industrial departments such as petrochemical industry, aviation, automobile making, dynamic power machine, air separation plant, profound hypothermia field, be all widely applied in recent years, be especially widely used at construction machinery industry.Although the heat exchange property of plate-fin heat exchanger has obtained people's accreditation, people do not abandon the pursuit of the heat exchanger to better heat exchange property all the time.Current plate-fin heat exchanger fin structure mainly contains continuous plain fin, corrugated fin and stagger arrangement saw tooth fin.Wherein the pressure drop of plain fin form is less, but causes the coefficient of heat transfer also less because fluid course is straight; Corrugated fin and the stagger arrangement saw tooth fin coefficient of heat transfer are relatively large, but because runner is that ripple type or sawtooth pattern cause runner pressure drop larger.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of new and effective plate-fin heat exchanger fin of the heat exchange property that can greatly improve heat exchanger is provided.
In order to achieve the above object, the technical solution used in the present invention is:
New and effective plate-fin heat exchanger fin of the present invention, it comprises stagger arrangement corrugated fin, described stagger arrangement corrugated fin is interrupted and staggers in each wavelength degree end, unit, and each unit ripple has an opening in centre makes each unit popin be divided into two halves.
The invention has the advantages that: the advantage that can simultaneously have stagger arrangement fin and corrugated fin concurrently, this fin is opened in the wavelength degree place's stagger arrangement of each unit, and at the position opening of half unit wavelength degree, can increase significantly mobile complexity, can effectively destroy Heat transfer boundary layer, so, can greatly improve the heat exchange property of heat exchanger.
Brief description of the drawings
Fig. 1 is the two-dimensional structure schematic diagram of new and effective plate-fin heat exchanger fin of the present invention;
Fig. 2 is the three-dimensional structure schematic diagram of new and effective plate-fin heat exchanger fin of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with specific embodiment.
New and effective plate-fin heat exchanger fin of the present invention as shown in drawings, it comprises stagger arrangement corrugated fin, described stagger arrangement corrugated fin is interrupted and staggers in each wavelength degree end, unit, and each unit ripple 1 has an opening in centre makes each unit popin be divided into two halves.In the unlikely situation that is subject to too much weakening of mechanical strength that a unit ripple dimidiation can be made to fin, effectively reduce the pressure drop of fin.
The wavelength d of preferred described unit ripple
2for 8-15mm, the wave amplitude A of described unit ripple is 1.5-2.0mm, and the pitch s of fin is 4.5-6mm.The thickness d of fin
1for 0.2-0.5mm; The height h of fin is 6-12mm.Can obtain higher heat transfer coefficient at this scope inner fin, lower pressure drop level.In addition, in fin machining process, change less to traditional fin machining mould.
Lift a specific embodiment below:
Fin configuration is staggered corrugated fin, and with each unit Bo Wei unit, fin stagger arrangement is opened.
The wavelength of each unit ripple is d
2=15mm.
The wave amplitude of unit ripple is A=2.0mm.
The pitch s=6mm of fin.
The thickness d of fin
1for 0.5mm; The height h of fin is 9.5mm.
The present embodiment with fin thickness, highly, unit wavelength, wave amplitude, pitch all identical conventional continuous wave pattern fin compare, under the condition that reaches same pressure drop, can make the coefficient of heat transfer improve 20-30%, fin weight reduces more than 10%.The present embodiment with fin thickness, highly, unit wavelength, wave amplitude, pitch all identical conventional saw tooth fin compare, under the condition that reaches the identical coefficient of heat transfer, pressure drop can reduce 5-10%, fin weight can reduce more than 5%.
