Description
Technical field
The present invention relates to a kind of novel plate-fin heat exchanger fins, belong to enhanced heat exchange and industrial energy saving technical field.
Background technique
Plate-fin heat exchanger is a kind of general thermal power mechanical equipment, because its coefficient of heat transfer is high, energy-saving effect is good, structure
The excellent properties such as compact, light and handy, aluminum design, are rapidly developed in every field.Early stage is mainly used in Automotive Aviation etc.
Industry has been widely applied to aviation, automobile, diesel locomotive, engineering machinery, space division, petrochemical industry, refrigeration, air-conditioning, profound hypothermia etc.
Field.China develops plate-fin heat exchanger since twentieth century the mid-1960s, and production fin has plain fin, fin with apertures
With three kinds of fins of serrated fin.
Plate-fin heat exchanger advantage is prominent, therefore, reinforces the theoretical research and research and development of products of plate-fin heat exchanger, make its
Wider field plays a role, energy-saving for China, and enterprise reduces production cost, improves device efficiency, reduces operation
Maintenance cost etc. is of great significance.But nowadays China, plate-fin heat exchanger research and development and manufacture level are lower, and research and development ability is weak,
There is no the autonomous property right of this aspect, the fin being able to produce is single, and main fin comes from import, and fin is plate fin heat-exchanging
The core component of device, the design of fin will directly influence the heat transfer effect of entire plate-fin heat exchanger.
Summary of the invention
In order to overcome above-mentioned deficiency, the present invention provides a kind of novel plate-fin heat exchanger fin, which is changed
Runner inner fluid speed can be improved in hot device fin, and boundary layer is thinned, and increases temperature gradient, when fluid flows through or enter 1/4 spherical shape
When backpack body, strong Secondary Flow is generated, to greatly improve its comprehensive performance.
The technical scheme adopted by the invention is that: novel plate-fin heat exchanger fin is by plain fin and 1/4 spherical backpack body
It is combined into, it is characterised in that: the fin material is aluminium, is cracked on tabula rasa first, and it is recessed then to stamp out intersection protrusion
It falls into, the spherical backpack body in the 1/4 of square arrangement, finally according to size roll forming.
The novel plate-fin heat exchanger fin overall dimension is identical as common fin, has good versatility,
It not only perfect can replace original fin, and can be used in mixed way individually or with common fin.
Described 1/4 spherical backpack body intersects protrusion and recess, square arrangement, when fluid flows through or enter 1/ on fin
When 4 spherical backpack body, the strong Secondary Flow of generation constantly impacts backpack body, and fluid boundary layer is thinned, to keep heat exchange comprehensive performance excellent
In common plate-fin heat exchanger fin.
The main structure parameters of the novel plate-fin heat exchanger fin have: fin heighth f , fin thicknessδ f , between wing is interior
Away froms f , 1/4 spherical backpack body radiusR, adjacent backpack body spacing c f , backpack body to fin back gaugeb f , the fin of different standards corresponds to phase
The structural parameters answered, make best performance.
The novel plate-fin heat exchanger fin, fin inner region formed media flow heat exchange runner, adjacent fins it
Between by membrane support, sealed between adjacent separator by sealing strip, fluid cracks direction inflow along vertical backpack body, makes different laminar flows
Body does not merge mutually, realizes the circulating forms such as fair current, adverse current, the cross-current of multiple flow and different fin layer fluids.
Compared with the common fin of existing plate-fin heat exchanger, the beneficial effects of the present invention are: the stream that 1, Novel fin is formed
Road, in the 1/4 spherical backpack body flowed through or into runner, fluid vertically flows into fluid in 1/4 spherical backpack body high spot, is wrapping
At body, the mutual impact of fluid, forms local differential pressure action above and below plain fin, so that longitudinal whirlpool and Secondary Flow are generated,
It guides mainstream to impact backpack body inner surface, improves the velocity gradient at backpack body；2, the novel plate-fin heat exchanger fin, stream
The flow velocity of the uneven formation regional area of speed and the pressure distribution of fluid is accelerated in road, so that boundary layer be thinned；3, very well
Versatility, not only perfect can replace original fin, and can be used alone or be used in mixed way with common fin.4, every
The fin of a standard corresponds to corresponding structural parameters, is optimised performance.

Specific embodiment
It is that 9.5mm makes into one the present invention in conjunction with attached drawing for fin thickness is the fin of 0.2mm with fin height
Walk explanation.
Fig. 1 is novel plate-fin heat exchanger fin overall schematic, and Fig. 2 is novel plate-fin heat exchanger fin front view,
Fig. 3 is novel plate-fin heat exchanger fin left view, in which: fin width isW, finned length isL, fin heighth f =
9.5mm, fin thicknessδ f =0.2mm, spacing in wings f =1.7mm, backpack body radiusR=0.9mm, adjacent backpack body spacing c f =2.7mm,
Backpack body is to fin back gaugeb f =1.8mm, Fig. 4 are novel plate-fin heat exchanger fin adjacent channels distribution map, and flow channel entry point is along vertical
It directly cracks direction in 1/4 spherical backpack body, includes runner 1 [4], runner 2 [5], runner 3 [6], fair current, adverse current, cross-current can be formed
Equal liquid forms can satisfy multiple flow flowing.
The runner that novel plate-fin heat exchanger fin of the invention is formed, fluid is in 1/4 ball flowed through or into runner
When shape backpack body, fluid is vertically flowed into 1/4 spherical backpack body opening, at backpack body, the mutual impact of two side liquid of plain fin,
The differential pressure action of part is formed, to generate longitudinal whirlpool and Secondary Flow, guidance mainstream impacts backpack body inner surface, makes at backpack body
Velocity gradient is improved；Since the flow velocity of the uneven formation High Velocity Area of speed and the pressure distribution of fluid in runner adds
Fastly, so that boundary layer be thinned；In conclusion the special construction accelerates local velocity in runner, boundary layer is thinned, increases temperature ladder
Strong secondary flow is spent and generated, integration capability is remarkably reinforced.
The processing method of the utility model plate-fin heat exchanger fin is further illustrated with reference to the accompanying drawing.
Preparation stage: according to the aluminium panels of measure corresponding size.
