Abstract
The invention relates to a fin structure for heat exchangers, the fin is of an integrated wavy structure, and the section of the fin is sequentially composed of a rectangular wave structure, a U-shaped wave structure and a bent wave structure. The fin structure is reasonable, can be stamped by a die to form in one step, is convenient to produce, enlarges the secondary heat exchange area, has a good heat exchange effect, and can enhance the overall performance of heat exchangers.
Description
Technical field
The present invention relates to technical field of heat exchangers, especially a kind of heat exchanger fin structure.
Background technology
Heat exchanger, claim again heat exchanger, heat passed to the device of another kind of heat-carrying agent from a kind of heat-carrying agent.In industrial processes, usually need to heat or cooling the i.e. transmission of heat.When a kind of fluid and one other fluid are carried out heat exchange and are not allowed to mix, just require to carry out in recuperative heat exchanger, be applied to the industries such as chemical industry, oil, power, food. the Main Function of heat exchanger is thermal energy exchange between cold fluid and hot fluid.
Fin is the most basic element of plate-fin heat exchanger, and conducting heat is mainly to rely on fin to complete, and a part is directly completed by dividing plate.And the fin heat transfer is direct heat transfer unlike dividing plate, therefore fin has the title on " secondary surface ".The heat exchanger fin structure is various at present, as various structures patterns such as sawtooth pattern, ripple type, flap type, punching type, flat types, the flow-disturbing ability of the expanding surface of fin and fin convection cell has determined heat-exchange capacity, can select suitable fin pattern according to different operating conditions.
In prior art, fin usually adopts independent parallelism structural to arrange and forms, and can't arrive its heat transfer effect in efficient plate-fin heat exchanger, and heat transfer effect is poor, affects the serviceability of heat exchanger.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of heat exchanger fin structure, thereby improves the serviceability of fin, improves heat transfer effect.
The technical solution adopted in the present invention is as follows:
A kind of heat exchanger fin structure, described fin is integral the formula concaveconvex structure, and the cross section of described fin is orthogonal wave structure, " U " shape wave structure and bending shape wave structure successively.
Its further technical scheme is:
The two ends of described fin are the square wave structure, are positioned at fin middle part interleaved setting " U " shape wave structure and bending shape wave structure;
Bending shape wave structure is: be provided with identical bending structure on each groove surface;
" U " shape wave structure is: its top and bottom are respectively arranged with evenly distributed " U " groove, and " U " groove of " U " groove on top and bottom is staggered.
Beneficial effect of the present invention is as follows:
The present invention is rational in infrastructure, by mould is one time punching molded, gets final product, and it is easy to make, has improved the secondary heat exchange area, good effect of heat exchange, the overall performance of raising heat exchanger.

Wherein: 1, fin; 2, square wave structure; 3, bending shape wave structure; 4, " U " shape wave structure.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the heat exchanger fin structure of the present embodiment, fin 1 is integral the formula concaveconvex structure, and the cross section of fin 1 is orthogonal wave structure 2, " U " shape wave structure 4 and bending shape wave structure 3 successively.
The two ends of fin 1 are square wave structure 2, be positioned at fin 1 middle part interleaved " U " shape wave structure 4 and bending shape wave structure 3 are set.
As shown in Figure 4, bending shape wave structure 3 is: be provided with identical bending structure on each groove surface.
As shown in Figure 5, " U " shape wave structure 4 is: its top and bottom are respectively arranged with evenly distributed " U " groove, and " U " groove of " U " groove on top and bottom is staggered.
Good heat dissipation effect of the present invention, be easy to clean, and heat exchange property is high, and compression capability is good, long service life.
The present invention adopts one time punching molded structure, the runner of its fluid is punched into uneven, thereby increase the turbulent extent of fluid, strengthening heat transfer, the flow-disturbing ability of its expanding surface and fin convection cell is several all higher than other, application is more in efficient plate-fin heat exchanger, is called as " high-effect fin ".
Above description is explanation of the invention, is not that limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification to the restriction of invention.
