Abstract

The invention discloses a radiating fin which comprises a plurality of fins, wherein the plurality of fins at least comprise a bump fin, and one side of the bump is provided with concave ribs, while the other side is provided with convex ribs. The radiating fin overcomes the defects of smaller secondary heat transfer area and low radiating efficiency of the radiating fin in the prior art and has the advantages of large secondary heat transfer area and high radiating efficiency through the design of the concave-convex shapes.

Description

A kind of fin

Technical field

The present invention relates to heat exchange facility field, relate in particular to the plate-fin heat exchanger fin.

Background technology

Fin occupies important role in the formation of radiator, except that the active heat removal of fan, evaluate the quality of a radiator, depends on the capacity of heat transmission of fin itself to a great extent.Fin is the important component part of fin, and the diabatic process of fin mainly relies on fin to finish.The structure of fin directly influences the secondary heat transfer area of fin, having that fin is commonly used is straight, sawtooth, three kinds of patterns of porous, serrated fin belongs to a kind of better performances a kind of fin commonly used, but his existing structure still causes the secondary heat transfer area of fin less, and radiating efficiency is restricted.

Summary of the invention

The objective of the invention is provides a kind of fin at above-mentioned shortcoming of the prior art, to realize the big and high advantage of radiating efficiency of secondary heat transfer area.

For achieving the above object, the technical solution used in the present invention is: a kind of fin, comprise a plurality of fins, and in described a plurality of fins, comprise a concavo-convex fin at least, be provided with concave bar in a side of described concavo-convex fin, opposite side is provided with convex tendon.This fin that has concavo-convex muscle mixes with other fins and is connected.It is different that the concave bar that increases and convex tendon make it and existing fin compare shape, can increase the secondary heat transfer area of fin.

Further, described concave bar is provided with near the top of concavo-convex fin.

Further, described convex tendon is provided with near the bottom of concavo-convex fin.

The invention has the beneficial effects as follows:

Increase concave bar and convex tendon by the both sides at the fin fin, make fin surface amass and increase, and then increased the secondary heat transfer area of fin, the present invention is simple in structure, novel, reasonable, has improved radiating efficiency.

The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.

In the present embodiment, shown in Fig. 1-9, fin of the present invention comprises: fin A, common fin B, the fin C with concavo-convex muscle, common fin D with concavo-convex muscle.

A kind of fin comprises fin A, B, C, D, is made by aluminium flake, and A, B, C, D are linked in sequence and form a fin unit together, and a plurality of fin units are joined together to form fin.

The concave bar of the oriented fin indent in the top in the left side of fin A, the outer convex tendon that protrudes of the oriented fin in the bottom on right side; The outer convex tendon that protrudes of the oriented fin in bottom in concavo-convex muscle fin C left side, the concave bar of the oriented fin indent in the top on right side; All hydraulically smooth surface about common fin B and D fin.

Concavo-convex muscle fin A and C go up design a series of concavo-convex muscle are arranged are in order to increase the area of dissipation of fin, and then increase the secondary heat transfer area of fin, improve rate of heat dispation.

Above-mentioned fin A, B, C, D can also adopt multiple arrangement connected mode, all can change heat radiating fin structure, increase the secondary heat transfer area of fin, improve rate of heat dispation.

It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.

Claims
