Abstract
The utility model relates to a fin structure for a heat exchanger. Fins are of an integrated concave-convex structure, and the sections of the fins are of a rectangular wave structure, a U-shaped wave structure and a bent wave structure in sequence. The fin structure for the heat exchanger is reasonable in structure, can be formed by a mould through one time of punching, is convenient to manufacture, improves the area of secondary heat exchange, is good in heat exchange effect, and improves the performance of the entire heat exchanger.
Description
Technical field
The utility model relates to technical field of heat exchangers, especially a kind of heat exchanger fin structure.
Background technology
Heat exchanger, claims again heat exchanger, heat is 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 fin heat transfer is direct heat transfer unlike dividing plate, therefore fin has the title on " secondary surface ".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 conventionally adopts independent parallelism structural to arrange and forms, and in efficient plate-fin heat exchanger, cannot arrive its heat transfer effect, and heat transfer effect is poor, affects the serviceability of heat exchanger.
Utility model content
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 scheme that the utility model adopts is as follows:
A heat exchanger fin structure, described fin is integral 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 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: on each groove surface, be provided with identical bending structure;
" 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.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, one time punching molded by mould, and it is easy to make, has improved 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 utility model 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 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: on each groove surface, be provided with identical bending structure.
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.
The utility model good heat dissipation effect, is easy to clean, and heat exchange property is high, and compression capability is good, long service life.
The utility model 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 compared with other, in efficient plate-fin heat exchanger, apply morely, be called as " high-effect fin ".
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
