The situation that the various energy is the most in short supply, the appropriate design of heat exchanger, operate and improve for saving fund,
It is highly important for material, the energy and space.
At present, the fin-tube heat exchanger on market is by radiating tube and the fin structure of several stackings
Becoming, radiating tube is connected in the louvre of fin, and its radiating principle is exactly that cold-producing medium flows through radiating tube,
Conduction of heat is distributed to fin, reaches radiating effect.But, existing fin-tube heat exchanger
Being supported by the flange of louvre between each fin, thus, flange height is difficult to too high, the most easily occurs
Cracking phenomena, but, if flange height is the lowest so that the gap between each fin reduces, Jin Er great
Affect greatly radiating efficiency, thus, be badly in need of solving.
Summary of the invention
Present invention aims to the problems referred to above, it is provided that a kind of heat radiating fin structure and production technology thereof, with
Solve to be supported by the flange of louvre between each fin of existing fin-tube heat exchanger, each fin
Between gap little, problem that radiating efficiency is low.
It is an object of the invention to be achieved through the following technical solutions:
A kind of heat radiating fin structure, including heat sink body, described heat sink body offers several for
The louvre of cross-under radiating tube, the outer rim of described louvre is provided with turn-up portion, in described heat sink body
Puncture and offer datum hole, the outer rim of described datum hole is provided with for increasing interval between each heat sink body
Datum hole flange, described datum hole flange includes being distributed in datum hole outer rim multiple and raises sheet, is arranged at and raises sheet
Top the support chip turned down laterally, datum hole flange is petal-like structures, described in raise the tapered structure of sheet,
And be arranged in a vertical direction.
As a preferred embodiment of the present invention, described louvre is circular port or slotted eye or kidney ellipsoid hole.
As a preferred embodiment of the present invention, described heat sink body is made up of aluminum.
As a preferred embodiment of the present invention, described sheet of raising is 5.
The production technology of a kind of fin, comprises the following steps:
A, piercing and flanging: stamp out louvre flange on tablet according to the hole shape of louvre, form flange
Portion；
B, puncturing: puncture punching on tablet and go out datum hole, and form the datum hole flange of homolysis, datum hole turns over
While be arranged in a vertical direction；
C, flange: the top of datum hole flange is carried out flange so that it is top turns down laterally.
Beneficial effects of the present invention is, described a kind of heat radiating fin structure turns over by arranging the datum hole of petal-like structures
Limit, on the premise of ensureing support strength, increases the gap between each fin, improves heat radiation effect
Rate, the production technology of described a kind of fin uses and punctures mode punching datum hole flange, and it is simple, convenient to have,
Non-waste feature.

Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.Permissible
Being understood by, embodiment described herein is used only for explaining the present invention, rather than limitation of the invention.
Refer to shown in Fig. 1 to Fig. 5, in the present embodiment, a kind of heat radiating fin structure, including by aluminum
The heat sink body 1 made, described heat sink body 1 offers several heat radiations for cross-under radiating tube
Hole 2, described louvre 2 is slotted eye, and the outer rim of louvre 2 is provided with turn-up portion 3, described heat radiation
Puncture on sheet body 1 and offer datum hole 6, the outer rim of described datum hole 6 is provided with for increasing each fin
The datum hole flange 7 at interval between body 1, described datum hole flange 7 includes 5 that are distributed in datum hole 6 outer rim and lifts
High sheet 4, being arranged at the support chip 5 raised sheet 4 top and turn down laterally, datum hole flange 7 is tied in petal-shaped
Structure, described in raise the tapered structure of sheet 4, and be arranged in a vertical direction.
Although it is noted that in the present embodiment, louvre 2 is slotted eye, but the present invention does not limits
In this, louvre 2 also can use circular port or kidney ellipsoid hole, and slotted eye is the preferred version of the present invention,
In the case of the cold-producing medium of same traffic, the rate of heat exchange of slotted eye is higher.
Although it is noted that in the present embodiment, the quantity raising sheet 4 is 5, but the present invention is not
Being limited to this, the quantity raising sheet 4 can increase as required or reduce, 5 settings raising sheet 4, and it supports
Intensity is more excellent.
Above-mentioned a kind of heat radiating fin structure is manufactured by following production technology:
The production technology of a kind of fin, comprises the following steps:
