Description
Technical field
The utility model relates to a kind of heat exchange core body of heat exchanger, particularly relates to a kind of fin heat exchanger core for fluid heat transfer.
Background technology
Plate-fin heat exchanger is the heat exchanger that a kind of heat exchange efficiency is higher, heat exchange core body is the core texture in heat exchanger, existing heat exchanger core body is a kind of fin heat exchanger core disclosed in Chinese invention patent CN 102003900A, be made up of the fin arranged between the dividing plate be parallel to each other and dividing plate, between adjacent dividing plate, the runner direction of fin is orthogonal.Fin in this kind of fin heat exchanger core adopts furnace brazing to connect into heat exchange core body, complex structure by polylith aluminium flake, and cost is higher.The cold and hot medium of each solder joint Long Term Contact, had not only affected heat exchange but also had been subject to fluid media (medium) corrosion, thus affected core body service life.This kind of fin heat exchanger core poor sealing performance simultaneously, fluid media (medium) in use has a small amount of situation about revealing, and can only be applicable to gas medium, and use and have certain limitation, adaptability is poor.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fin heat exchanger core that a kind of structure is simple, cost is low, easy for installation, adaptability is good.
A kind of fin heat exchanger core of the utility model, comprise dividing plate, fin and cover plate, described dividing plate is arranged with multilayer in parallel at vertical direction, described fin is between adjacent two layers dividing plate, described cover plate is arranged on above the superiors' dividing plate, wherein said dividing plate comprises base plate and two side plates, described base plate cross section is square, described two side plates to be positioned on two relative limits of base plate and vertical with base plate, the side plate of adjacent two layers dividing plate is mutually vertical, the top of lower partition side plate is together with the bottom welding of upper partition, the height of described fin is slightly less than the height of dividing plate side plate.
A kind of fin heat exchanger core of the utility model, wherein said dividing plate employing thickness is that the steel plate bending of 1 ~ 2mm is shaping.
A kind of fin heat exchanger core of the utility model, the cross section of wherein said fin is multiple continuous print side tooth profiles.
A kind of fin heat exchanger core of the utility model, the aluminium foil that wherein said fin is or the disposable punch forming of stainless steel materials, thickness is 0.1 ~ 0.6mm.
A kind of fin heat exchanger core of the utility model, wherein said cover plate selects thickness to be more than or equal to the steel plate of 3mm.
A kind of fin heat exchanger core difference from prior art of the utility model is that a kind of fin heat exchanger core of the utility model only includes dividing plate, fin and cover plate, and structure is simple; Wherein be welded into entirety between adjacent separator and integral sealing is good, the cold fluid and hot fluid in adjacent two layers fin can be separated completely, be convenient to adapt to various different fluid media (medium).Fin is formed by one piece of sheet fabrication, is injected by fin in the space formed between adjacent separator, install very convenient during installation, and polylith dividing plate and fin can make standard module, arbitrarily assembles according to demand; Fin cross section is continuous print side tooth profile, considerably increases heat exchange area, and heat exchange area per unit volume is the several times of tube-sheet heat exchanger, and heat exchange efficiency is higher.
Below in conjunction with accompanying drawing, a kind of fin heat exchanger core of the present utility model is described further.

Detailed description of the invention
As shown in Figure 4, a kind of fin heat exchanger core of the utility model comprises dividing plate 1, fin 2 and cover plate 3, and dividing plate 1 is arranged with multilayer in parallel at vertical direction.As shown in Figure 1, dividing plate 1 comprises base plate and two side plates, and base plate cross section is square, and two side plates to be positioned on two relative limits of base plate and vertical with base plate, the side plate of adjacent two layers dividing plate 1 is mutually vertical, and dividing plate 1 adopts thickness to be that the steel plate bending of 1 ~ 2mm is shaping.As shown in Figure 4, the top of lower partition 1 side plate, together with the bottom welding of upper partition 1, forms a cavity between upper lower clapboard 1.The inside cavity that fin 2 is formed between adjacent two layers dividing plate 1.As shown in Figures 2 and 3, fin 2 is aluminium foil or the disposable punch forming of stainless steel materials of 0.1 ~ 0.6mm by a monoblock thickness, the cross section of fin 2 is multiple continuous print side tooth profiles, and the height of fin 2 is slightly less than the height of dividing plate 1 side plate, makes it just can insert in the cavity between adjacent separator 1.As shown in Figure 4, cover plate 3 is arranged on above the superiors' dividing plate 1, and cover plate 3 selects thickness to be more than or equal to the steel plate of 3mm.
A kind of fin heat exchanger core operation principle of the utility model is as follows: heat source fluid flows through the fin 2 in dividing plate 1 cavity, heat is passed to fin 2, heat is passed to the fin 2 of lower floor by fin 2 by the dividing plate 1 below it, finally heat is passed to the fluid (heated medium) flowing through lower floor's fin 2, complete the process once heat being passed to another kind of medium from a kind of medium.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
