Abstract
The invention discloses a plate-fin heat exchanger which is formed by brazing multiple plate sheet sets and multiple fins at intervals in an implanting mode. Each plate sheet set comprises two identical plate sheets, water channels and ribs are arranged on the plate sheets, every two plate sheets are overlapped inversely to form a water path, openings are formed in the plate sheets in a central axis symmetry mode, holes are correspondingly formed in the fins, after the fins are implanted into the plate sheet sets, forming is carried out through one-time brazing, and the main flow path of the plate sheet sets is formed by overlapping the openings formed in the plate sheets in the central axis symmetry mode and the corresponding holes of the fins. The plate-fin heat exchanger is simple in processing and manufacturing, only two kinds of accessories (the plate sheets and the fins) need to be stamped, one-time forming can be achieved through overlapping brazing, the plate sheets form water flow ways, components are saved, heat loads can be increased, the heat effect is improved, the problems of the air stagnation phenomenon of transverse small space above the water paths, water resistance and air resistance are effectively solved through the hole punching structure and the hole forming mode of the plate sheets, and heat exchange efficiency is high.
Description
Technical field
The present invention relates to a kind of heat exchanger, in particular, is a kind of for plate fin type heat exchangers such as gas fired-boiler, burnt gas wall hanging furnace, gas heaters.
Background technology
Existing like product, usually superimposed alternately with plate and fin, surrounding seals fin with a plurality of end sockets, and the space of fin forms air flue, has water inlet manifold (and water inlet) and total outlet pipe (mouth) of welding separately, the common body of its water channel or flat tube; Plate wherein is mainly used in separating adjacent two fins, to form water route or gas circuit, and certain strong effect is arranged.Parts are more, and small product size is large (taking up room), and production and maintenance cost are higher, complex process, and thermal effect is lower, and can't accomplish one-shot forming.
Summary of the invention
The technical problem that the present invention solves is for above-mentioned deficiency, provide a kind of simple in structure, parts are less, with low cost, volume is small and exquisite, thermal effect is higher, and can one-time formed heat exchanger, and plate of the present invention itself forms water flow passage, save parts, and can increase thermic load, improve thermal effect.
Technical scheme of the present invention is as described below: a kind of plate fin type heat exchanger, it is characterized in that, it is by a plurality of plate groups implantation lead welding and shaping alternate with fin, described plate groups comprises two identical plates, be equipped with tank and rib on described plate, the two boards sheet is oppositely superimposed, form water route, be arranged with perforate with axis on described plate, fin is corresponding aperture also, after the alternate implantation fin of a plurality of plate groups, disposable lead welding and shaping, total runner of described plate groups is formed by stacking with axisymmetric perforate in plate and corresponding fin perforate.
Further, described plate and fin are punch forming.
Further, described plate tapping strikes out annular protrusion, and this protuberance, a little more than the basic plate face of plate, is highly just in time half of fin height.
According to above-mentioned beneficial effect of the present invention, be: processing and fabricating of the present invention is simple, only need two accessories of punching press (plate and fin), superimposed soldering gets final product one-shot forming, and plate itself forms water flow passage, saves parts, and can increase thermic load, improve thermal effect, the structure of the punching of plate and perforate mode, solve the stagnation of the circulation of vital energy phenomenon in laterally small size space, top, water route effectively, and solving water resistance and vapour lock problem, heat exchange efficiency is high.

The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention; technical scheme in the embodiment of the present invention is clearly and completely described; certainly; described embodiment is only the present invention's part embodiment; rather than whole embodiment; based on claim in the present invention, except embodiment but belong in the claim scope, also all belong to the scope of protection of the invention.
As accompanying drawing 1, shown in Fig. 2, Fig. 3 Fig. 4, Fig. 5, primary structure of the present invention is basically with regard to two parts: plate 1 and fin 2(total water inlet or the another weld-end fittings of delivery port or screw interface), and all punch formings, plate is provided with tank and rib, two same plates are oppositely superimposed, can form water route; Implant a fin between superimposed plate groups; Be arranged with perforate with axis on plate, fin is corresponding aperture also, after a plurality of plate groups are implanted fin, disposable lead welding and shaping, form product of the present invention, total runner of plate is formed by stacking with axisymmetric perforate in plate corresponding fin perforate, in addition, the plate tapping strikes out annular protrusion, and this protuberance, a little more than the basic plate face of plate, is highly just in time half of fin height, thus, product one-shot forming of the present invention, plate directly forms water flow passage, and the gap of fin forms the runner of air-flow.Water channel of the present invention, can make single channel or dual channel etc.
Plate fin type heat exchanger product first and second heat exchange area of the present invention exceeds 60% than like product, and thermal effect can reach 109% through experiment, and heat exchange efficiency is high.Processing and fabricating is simple, only needs two accessories of punching press (plate and fin), and superimposed soldering gets final product one-shot forming, reduces by 70% number of fitting parts than traditional product, and cost subtracts greatly; The structure of the punching of plate and perforate mode, solve the stagnant phenomenon in laterally small size space, top, water route effectively, and solve water resistance and vapour lock problem.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
The above has carried out exemplary description to patent of the present invention by reference to the accompanying drawings; obviously the realization of patent of the present invention is not subject to the restrictions described above; as long as adopted the method design of patent of the present invention and the various improvement that technical scheme is carried out; or without improving, the design of patent of the present invention and technical scheme are directly applied to other occasion, all in protection scope of the present invention.
