Abstract

The utility model discloses a kind of heat exchanger fin, comprise plate body, described plate body is provided with multiple row pore spaced apart, and the two ends of described plate body are waveform otch, and described waveform otch is parallel to each other and can encloses a complete curved surface.The utility model avoids the generation of leftover pieces, and the use realizing material maximizes, and reduces cost, improves economic benefit.

Description

A kind of heat exchanger fin

Technical field

The utility model relates to heat exchanger, particularly a kind of heat exchanger fin.

Background technology

Gilled radiator is the most widely used a kind of heat transmission equipment in gas and liquid heat exchanger, and it is primarily of the formation such as heat exchanger tube, fin.The traditional fin used in the market is formed by machine punching press usually, a large amount of leftover pieces are often produced in pressing process, so a large amount of leftover pieces are difficult to recycling, cause a large amount of wastes, virtually improve production cost, reduce enterprise competitiveness, there is the space of improvement.

Utility model content

The utility model is to overcome defect in above-mentioned prior art, provides a kind of fin that leftover pieces can be avoided to produce.

For achieving the above object, the utility model provides a kind of heat exchanger fin, comprises plate body, and described plate body is provided with multiple row pore spaced apart, the two ends of described plate body are waveform otch, and described waveform otch is parallel to each other and can encloses a complete curved surface.

By above-mentioned setting, a raw material can be cut into polylith fin continuously, and do not have the generation of leftover pieces, at utmost make use of raw material, reduce cost.

Be set to further: described plate body is provided with projection, described projection and pore spaced apart, be often provided with projection between adjacent two tubulation holes.

Be set to further: the shape of described pore is for circular or oval.

Compared with prior art, waveform cuts parallel of the present utility model and the waveform otch of both sides can enclose a complete curved surface, thus the polylith fin of a material cutting, thus make use of material to the full extent, avoid the generation of leftover pieces, reduce production cost, improve economic benefit.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of arrangement in groups of the utility model fin;

Fig. 2 is the perspective view of the utility model fin.

Mark the following drawings mark thereon by reference to the accompanying drawings:

1-plate body; 2-pore; 3-waveform otch; 4-is protruding.

Detailed description of the invention

Below in conjunction with accompanying drawing, a detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.

The utility model fin as shown in Figure 1, comprise plate body 1, plate body 1 is provided with the equally distributed pore 2 of multiple row, the shape of pore 2 is preferably oval, also can be that circle waits other shapes, the pore 2 that plate body 1 is arranged can be all oval, also can be all circular or other forms, also can be various states combination distribution, can select according to actual needs; Be provided with protruding 4 between adjacent two tubulation holes 2, this projection 4 can be salient point, boss, and the punching edge flange that also can be formed by plate body 1 punching press or bridging are formed, for shunting hot-fluid; The waveform otch 3 of plate body 1 both sides is parallel and can enclose a complete curved surface, namely the trough of side waveform otch 3 is corresponding with the crest of opposite side waveform otch 3, the crest of side waveform otch 3 is corresponding with the trough of opposite side waveform otch 3, thus a material can be cut into polylith fin continuously, and do not produce leftover pieces, make use of material to the full extent, achieve benefit, reduce cost, improve benefit.

Compared with prior art, the utility model make use of the raw material of cutting fin to the full extent, avoids the generation of leftover pieces in cutting process, reduces cost, increases the benefit, and achieves economic maximization.

Be only a specific embodiment of the present utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
