Abstract

The utility model discloses a cooling fin, include: set up a plurality of fins on the base, set up the arch on the fin. The arch is punching press and going out on the fin. An embodiment is the arch is punching press and going out on a face of fin. An embodiment is again the arch is punching press and going out on two faces of fin. Compared with the prior art, the utility model discloses a cooling fin has set up a plurality of archs on the fin, and each arch can the single face setting, also can two -sidedly set up, consequently, how to fix a position in actual application regardless of cooling fin, generates heat the turbulent flow that causes by the arch and has strengthened the intensity that the air flows for the cooling fin radiating effect promotes greatly.

Description

A kind of fin

Technical field

This utility model is related to a kind of fin, and espespecially one kind prepares raised, the radiating of increase area of dissipation on fin Piece.

Background technology

At present the conventional structure of the finned radiator of LED lamp is as shown in figure 1, the one side in one piece of base plate 1 is provided with Multiple fins 2, each fin 2 is individually fixed or is connected as one by pipe or other forms, in order to improve heat-sinking capability, also One or more hole 3 can be provided with the middle of fin 2, the finned radiator of this structure is relatively simple to manufacture, but the effect that radiates Really bad, particularly installation direction has an impact to radiating：When the gap direction between fin 2 is perpendicular to the ground, base plate hangs down with ground When straight, fully, radiating effect is best for cross-ventilation；

When base plate is parallel to the ground, fin 2 is at the top of base plate, or conversely, radiating effect is deteriorated；

When the gap between fin 2 is parallel to the ground, when base plate is perpendicular to the ground, it is impossible to form effective cross-ventilation, dissipate Thermal effect is worst.

Although being provided with hole 3 in the middle of above-mentioned fin fin 2, when air-flow is without flow through fin surface, radiating effect is very poor.

Therefore, the radiator of prior art is necessary to be improved.

Such as application number：201510943335.1 the applying date：So the Chinese invention patent of 2015-12-16 is exactly, its Technical scheme is：

The present invention discloses a kind of radiator, including multiple radiating fins, extends along radiating fin on each radiating fin Direction be vertically provided with several for ventilation bar hole, the bar hole corresponding setting of difference on two neighboring radiating fin. Bar hole is vertically provided on radiating fin in the present invention, and the heat between two radiating fins can not only be along in radiating fin Between flow out along the direction that radiating fin extends, and heat can be with the distinguished and admirable bar hole between two radiating fins Lower flowing and diffusion, and will not be hindered, this makes it possible to give full play to the radiating effect of bar hole, heat radiation device Radiating efficiency.

As can be seen that the fin has not big enough the shortcoming of area of dissipation.

Utility model content

In order to solve prior art when base plate is parallel to the ground, fin is at the top of base plate, or conversely, radiating effect It is deteriorated；Or when the gap between fin is parallel to the ground, when base plate is perpendicular to the ground, it is impossible to form effective cross-ventilation, dissipate Thermal effect is worst；Or although hole is provided with the middle of fin, when air-flow is without flow through fin surface, radiating effect is very poor to ask Topic, this utility model provides a kind of fin, solves the problems referred to above.

This utility model is by being realized using following technical scheme：

Manufacture and design a kind of fin, including：

Some fins are set on one base, arrange raised on the fin.

The projection on fin punching press and go out.

A kind of embodiment be the projection be on a face of fin punching press and go out.

Another embodiment be the projection be on two faces of fin punching press and go out.

Compared with prior art, fin of the present utility model is provided with multiple projections on fin, and each projection can With one side setting, it is also possible to two-sided setting, therefore, no matter how fin positions in practice, caused by raised heating Turbulent flow increase the intensity of air flow so that fin radiating effect is greatly promoted.

Specific embodiment

Below in conjunction with the accompanying drawings shown most preferred embodiment makees further description in detail to this utility model：

Manufacture and design a kind of fin as shown in Figure 2 to 4.

This utility model includes：

Some fins 2 are set on one base 1, raised 4 are arranged on the fin 2.

Described raised 4 on fin 2 punching press and go out.

The first embodiment be described raised 4 be on a face of fin 2 punching press and go out.

Another embodiment be described raised 4 be on two faces of fin 2 punching press and go out.

After punching press, raised hole 5 is left in fin 2.

The projection 4 being stamped and formed out, is the material of of fin 2 itself, and is joined directly together one with fin 2, and heat is from fin 2 The ability being transmitted on raised 4 is identical with fin 2 itself.

While punching press fin 2, a raised hole 5 is formed in correspondence position, this hole can be used as the flowing of thermal current Passage.

After being stamped and formed out raised 4, the cooling surface area of fin 2 is not only reduced, accordingly increase the radiating table of fin 2 Area.

After heatsink temperature is raised, hot-air can form a kind of air current flow of active, and in air-flow these projections 4 are flow through When with raised hole 5, a kind of disorderly air-flow can be formed, this disorderly air-flow is beneficial to the heat for taking away fin surface.

No matter what angle this fin is in, effective radiating airflow can be all formed, can be effectively improved scattered Thermal effect.

This utility model has been carried out and demonstrates its advantage.

Above content is to combine specific preferred implementation further detailed description of the utility model, it is impossible to Identification is of the present utility model to be embodied as being confined to these explanations.For the ordinary skill of this utility model art For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be regarded To belong to protection domain of the present utility model.
