Abstract
The utility model discloses a combined heat exchanger, and particularly relates to a heat exchanger fin combined by different structures. The heat exchanger comprises a straight fin heat exchange part consisting of a plurality of ridges arranged side by side, and is characterized in that the straight fin heat exchange part is connected with a sawtooth fin heat exchange part. The utility model not only improves the heat transfer efficiency, but also has appropriate flow resistance, utilizes the respective advantages of a straight fin and a sawtooth fin, and has higher heat transfer coefficient in comparison with the straight fin and smaller flow resistance in comparison with the sawtooth fin. The combined structure of the fin facilitates the fluid turbulence and regeneration of boundary layer. The combined heat exchanger has the advantages of enhanced heat exchange capability and improved bearing capacity when used on occasions requiring lower flow resistance.
Description
Technical field
The utility model relates to a kind of heat exchanger, is specifically related to a kind of heat exchanger fin that different structure is combined.
Background technology
The heat exchanger that uses in the prior art is varied, and the fin that each heat exchanger adopts all has its characteristics separately, and its fin pattern commonly used comprises flat type fin, porous type fin, louvered fin, rippled fin and serrated fin etc.Wherein, the flat type fin structure is the simplest, and flow resistance is less, manufactures easily, and cost is lower, but heat transfer coefficient is lower; The serrated fin heat-transfer effect is good, but flow resistance is bigger, and processing is complicated.Along with the range of application of plate-fin heat exchanger is more and more wider, the performance of fin also to be had higher requirement, the demand of development of new fin is also more and more urgent.
The utility model content
For the fin limitation of single structure in the solution prior art is big, the problem that can not have complementary advantages between each fin, the utility model provides a kind of combined fin that flat type fin, serrated fin are combined.Concrete scheme is as follows: a kind of combined type fin, comprise the flat type fin heat exchange portion that a plurality of tongues are side by side formed, and it is characterized in that described flat type fin heat exchange portion is connected with serrated fin heat exchange portion.
Another optimal way of the present utility model: described serrated fin heat exchange portion forms a plurality of regularly arranged protuberances by flat type fin heat exchange portion and constitutes in the tongue side, protuberance on the single tongue of serrated fin heat exchange portion is continuous " U " shape, and the tongue protuberance of whole serrated fin heat exchange portion is symmetric arrays.
Another optimal way of the present utility model: flat type fin heat exchange portion and serrated fin heat exchange portion are one time punching molded.
Another optimal way of the present utility model: the ratio of described flat type fin heat exchange portion and serrated fin heat exchange portion is 1: 1.
Another optimal way of the present utility model: the ratio of described flat type fin heat exchange portion and serrated fin heat exchange portion is 2: 1.
Another optimal way of the present utility model: the ratio of described flat type fin heat exchange portion and serrated fin heat exchange portion is 1: 2.
Fin in the utility model heat exchanger can either improve heat transfer efficiency can have moderate flow resistance again, flat type fin and serrated fin advantage have separately been utilized, compare with plain fin, has higher heat transfer coefficient, compare with saw tooth fin, have less flow resistance, the fin structure after the combination helps the disturbance and the renewal of boundary layer fluid, the utility model is requiring the lower occasion of flow resistance, has the advantage that increases exchange capability of heat, improves bearing capacity.

The specific embodiment
As shown in Figure 1, 2, 3, the fin in the utility model heat exchanger combines the fin of two kinds of shapes, forms a kind of combined type fin fast, that air drag is little that conducts heat.This programme utilizes on a substrate towards the wing machine and extrudes a plurality of rectangle type tongues 3 arranged side by side, forms flat type fin heat exchange portion 1.End in flat type fin heat exchange portion 1, the side of each tongue 3 is all extruded a plurality of protuberances 4 side by side, form staggered " U " shape zigzag on each tongue 3, form serrated fin heat exchange portion 2, the protuberance 4 of serrated fin heat exchange portion 2 interior all tongues 3 is symmetric arrays all.In the combined type fin, flat type fin heat exchange portion 1 and serrated fin heat exchange portion 2 shared ratios can be looked actual needs and be adjusted arbitrarily, several structures such as flat type fin heat exchange portion 1 commonly used has 1: 1 with the ratio of serrated fin heat exchange portion 2,2: 1 and 1: 2.Flat type fin heat exchange portion 1 and serrated fin heat exchange portion 2 can utilize towards wing machine one-shot forming manufacturing.
