Abstract
The invention discloses a graphite heat conduction and dissipation piece. The graphite heat conduction and dissipation piece comprises a graphite substrate, protrusions and a groove are formed at the graphite substrate, and the protrusions and the groove are continuously distributed. Because the protrusions and the groove continuously distributed are formed at the graphite substrate, the graphite substrate is in a concave-convex shape. In this way, the concave-convex shape of the graphite substrate can be set according to the concave-convex condition of the surface of a mobile phone component so that the graphite substrate can adhere to all the parts of the surface of the component, and heat of the mobile phone component can be effectively dissipated in time; the using performance of the mobile phone component is guaranteed, and the service life of the mobile phone component is prolonged.
Description
Technical field
The present invention relates to heat conduction and heat radiation materials application field, particularly a kind of graphite heat conducting and heat radiating fin of heat conduction and heat radiation.
Background technology
In recent years, along with the development of electronic technology, electronic product especially mobile phone continuous renewal regenerate, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, its caloric value is also increasing, therefore often adopts graphite heat radiation fin as the preferred material solving mobile phone heat conduction and heat radiation.
In prior art, usually between mobile phone part, graphite heat radiation fin is pasted, to reach the object of heat conduction and heat radiation, the upper surface of graphite heat radiation fin and lower surface are uniform planar structure, but, because the surface being pasted with the mobile phone part of graphite heat radiation fin is not entirely uniform plane, that have or even rough and uneven in surface, the surface of partial component will be caused so not paste graphite heat radiation fin, thus cause the heat of this partial component not left by graphite heat radiation fin derivation timely and effectively, the continuous accumulation of heat will certainly affect the serviceability of mobile phone part, even can shorten the useful life of component, very large inconvenience is brought to enterprise.
Summary of the invention
For solving Problems existing in above-mentioned background technology, the object of the present invention is to provide a kind of graphite heat conducting and heat radiating fin, to reach the object that the various piece making mobile phone part surface all pastes graphite heat radiation fin.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of thermal conductivity graphite radiating fins, comprise graphite matrix, described graphite matrix is provided with projection and groove, described projection and described groove are continuous distribution.
Preferably, described graphite matrix is artificial graphite flake.
Pass through technique scheme, graphite heat conducting and heat radiating fin provided by the invention, by graphite matrix being arranged projection and the groove of continuous distribution, make graphite matrix concave-convex surface, so namely according to the convex-concave situation on mobile phone part surface, the convex-concave shape of graphite matrix can be set, make graphite matrix can paste the various piece of component surface, timely and effectively the heat of mobile phone part is derived and leave, ensure that the serviceability of mobile phone part, extend its useful life.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
The main TV structure schematic diagram that Fig. 1 is a kind of graphite heat conducting and heat radiating fin disclosed in the embodiment of the present invention one.
In figure, number designation represents the title of parts:
1, electrographite sheet 2, projection 3, groove
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
A kind of thermal conductivity graphite radiating fins provided by the invention, as shown in Figure 1, comprises electrographite sheet 1, electrographite sheet 1 is provided with protruding 2 and groove 3, and projection 2 and groove 3 are in continuous distribution.
A kind of graphite heat conducting and heat radiating fin disclosed by the invention, by graphite matrix being arranged projection and the groove of continuous distribution, make graphite matrix concave-convex surface, so namely, can according to the convex-concave situation on mobile phone part surface, the convex-concave shape of graphite matrix is set, makes graphite matrix can paste the various piece of component surface, the heat of mobile phone part is derived leave timely and effectively, ensure that the serviceability of mobile phone part, extend its useful life; Meanwhile, this graphite heat conducting and heat radiating fin makes simple, with low cost, and practical flexibly.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention 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.
