Abstract

The utility model discloses a plate-fin heat exchanger. The plate-fin heat exchanger is formed in a brazing mode by planting a plurality of plate sets and fins alternately. Each plate set comprises two same plates, wherein the plates are provided with water channels and ribs respectively, and the two plates are superimposed in the opposite direction to form a water way. Open holes are formed in the plates symmetrical about the central axis, and open holes are correspondingly formed in the fins. After the fins are planted between the multiple plate sets alternately, one-time brazing forming is performed, and a main flow channel of the plate sets is formed by superimposing the open holes of the plates symmetrical about the central axis and the corresponding fins. The plate-fin heat exchanger is easy to machine and manufacture, and the plate-fin heat exchanger can be formed at a time just by punching, superimposing and brazing the two accessories (the plates and the fins); because the water flow channel is formed by the plates, components are saved, thermal loads can be increased, and thermal efficiency can be improved; because of the punched hole structure and the hole forming mode of the plates, the problem of air stagnation in a small transverse space above the water way is effectively solved, the problems of water resistance and air resistance are solved, and the heat exchange efficiency is high.

Description

Plate fin type heat exchanger

Technical field

The utility model 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, conventionally superimposed alternately with plate and fin, surrounding seals fin with multiple 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 is wherein mainly used in separating adjacent two fins, to form water route or gas circuit, and has certain strong effect.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 cannot accomplish one-shot forming.

Summary of the invention

The technical problem that the utility model solves is for above-mentioned deficiency, provide a kind of simple in structure, parts are less, with low cost, volume is small and exquisite, and thermal effect is higher, and can one-time formed heat exchanger, plate of the present utility model itself forms water flow passage, save parts, and can increase thermic load, improve thermal effect.

The technical solution of the utility model is as described below: a kind of plate fin type heat exchanger, it is characterized in that, it is by multiple plate groups implantation lead welding and shaping alternate with fin, described plate groups comprises two identical plates, on described plate, be equipped with tank and rib, two boards sheet is oppositely superimposed, form water route, on described plate, be arranged with perforate with axis, fin is corresponding aperture also, after the alternate implantation fin of multiple 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 the half of fin height.

Be according to above-mentioned the utility model beneficial effect: the utility model processing and fabricating 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 utility model embodiment; technical scheme in the utility model embodiment is clearly and completely described; certainly; described embodiment is only the utility model part embodiment; rather than whole embodiment; based on claim in the utility model, except embodiment but belong within the scope of claim, also all belong to the scope of the utility model protection.

As accompanying drawing 1, shown in Fig. 2, Fig. 3 Fig. 4, Fig. 5, the utility model primary structure is substantially 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; Between superimposed plate groups, implant a fin; On plate, be arranged with perforate with axis, fin is corresponding aperture also, multiple plate groups are implanted after fin, disposable lead welding and shaping, form product of the present utility model, total runner of plate is formed by stacking with axisymmetric perforate in plate corresponding fin perforate, in addition, plate tapping strikes out annular protrusion, and this protuberance, a little more than the basic plate face of plate, is highly just in time the half of fin height, thus, the one-shot forming of the utility model product, plate directly forms water flow passage, and the gap of fin forms the runner of air-flow.The utility model water channel, can make single channel or dual channel etc.

The utility model plate fin type heat exchanger product first and second heat exchange area exceeds 60% compared with 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, effectively solve the stagnant phenomenon in laterally small size space, top, water route, 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 the utility model claims.

By reference to the accompanying drawings the utility model patent is carried out to exemplary description above; obviously the realization of the utility model patent is not subject to the restrictions described above; as long as adopted the method design of the utility model patent and the various improvement that technical scheme is carried out; or without improving, the design of the utility model patent and technical scheme are directly applied to other occasion, all at protection domain of the present utility model.
