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 utility model provides a kind of novel plate-fin heat exchanger fin, the new type of plate wing
Runner inner fluid speed can be improved in formula heat exchanger fin, and boundary layer is thinned, and increases temperature gradient, when fluid flows through or enter 1/4
When spherical backpack body, strong Secondary Flow is generated, to greatly improve its comprehensive performance.
Technical solution used by the utility model is：Novel plate-fin heat exchanger fin is spherical by plain fin and 1/4
Backpack body is combined into, it is characterised in that：The fin material is aluminium, is cracked on tabula rasa first, and it is convex then to stamp out intersection
Play recess, 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 utility model has the beneficial effects that：1, Novel fin is formed
Runner, 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,
At backpack body, the mutual impact of plain fin fluid up and down forms local differential pressure action, to generate longitudinal whirlpool and secondary
Stream, guidance mainstream impact backpack body inner surface, improve the velocity gradient at backpack body；2, the novel plate-fin heat exchanger wing
Piece, the flow velocity of the uneven formation regional area of speed and the pressure distribution of fluid is accelerated in runner, so that boundary layer be thinned；3,
Good versatility not only perfect can replace original fin, and can be used alone or be used in mixed way with common fin.
4, the fin of each standard corresponds to corresponding structural parameters, is optimised performance.
