Description

A kind of CPU radiating fin

Technical field

The utility model relates to heating radiator industry, particularly relates to a kind of CPU radiating fin.

Background technology

In recent years, along with the processing power of cpu central processing unit constantly strengthens, power consumption increases thereupon, therefore creates huge heat, needs to use sizable heat radiator to dispel the heat.But the development trend of computer is more and more slim, the installing space leaving heat radiator for is less, therefore needs a kind of small and exquisite and heat radiator of excellent heat dissipation performance of design.

Utility model content

For the deficiencies in the prior art, the technical matters that the present invention solves is to provide a kind of small and exquisite and CPU radiating fin of excellent heat dissipation performance.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of CPU radiating fin, comprises substrate, the end face of substrate is provided with the radiating fin vertical with described substrate, the left and right sides of described radiating fin have tooth-shape structure; The side of described substrate is provided with several air conducting hole.

Preferably, the bottom surface of described substrate is provided with three groups of locating convex blocks, and each described locating convex block has a draw-in groove.

Preferably, described in every root, the tapering of radiating fin is 1 °.

Compared with prior art, the beneficial effects of the utility model are: in the left and right sides of radiating fin, have tooth-shape structure, under the prerequisite not increasing heating radiator volume, add the area of radiating fin side, and then increase the area of dissipation of heating radiator, improve the heat dispersion of heating radiator.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.

The front view of a kind of CPU radiating fin that Fig. 1 provides for the utility model embodiment one;

Fig. 2 is the enlarged diagram at A place in Fig. 1;

The upward view of a kind of CPU radiating fin that Fig. 3 provides for the utility model embodiment two.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

Embodiment one

See Fig. 1 and 2, a kind of CPU radiating fin, comprises substrate 1, the end face of substrate 1 is provided with the radiating fin 2 vertical with substrate 1, the left and right sides of radiating fin 2 has tooth-shape structure 3; The side of substrate 1 is provided with several air conducting hole 4, and air conducting hole 4 is also in peripheral space by a part of spread heat.

Embodiment two

See Fig. 1 and 3, with embodiment one unlike, the bottom surface of substrate 1 is provided with three groups of locating convex blocks 5, and each locating convex block has a draw-in groove 6.Draw-in groove, for heat radiator is stuck in CPU, improves positioning precision after being provided with draw-in groove, makes heating radiator and treats that the contact of thermal component is more excellent, greatly improving the performance of heat radiation.The xsect of radiating fin 2 is all up-small and down-big, and the shape of cross section of each strip radiating fin 2 is identical, and the tapering of every root radiating fin 2 is 1 °.

In sum, the beneficial effects of the utility model are: in the left and right sides of radiating fin, have tooth-shape structure, under the prerequisite not increasing heating radiator volume, add the area of radiating fin side, and then increase the area of dissipation of heating radiator, improve the heat dispersion of heating radiator.

To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
