Abstract
The invention discloses a novel graphite sheet, which includes a natural graphite flake and an artificial graphite flake that are sticked by a double-sided adhesive or coating glue. By sticking the natural graphite flake and the artificial graphite flake, the heat conduction and dissipation properties of the natural graphite flake are enhanced, and also the thickness of the artificial graphite flake is increased, so that the novel graphite sheet has a wider applicable range during use.
Description
Technical field
The Heat Conduction Material application that the present invention relates to dispel the heat, the novel graphite sheet that particularly a kind of heat conduction of dispelling the heat is used.
Background technology
In recent years, along with the development of electronic technology, electronic product is constantly updated and is regenerated, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, and its caloric value is also increasing, therefore not only requires it to be equipped with corresponding heat abstractor, also to guarantee that heat abstractor has stronger heat-sinking capability, to ensure the reliability of properties of product and to extend its service life.
Graphite heat conducting heat sink material, because its distinctive low-density (with respect to metal species) and high heat conduction and heat radiation coefficient and low thermal resistance become hyundai electronics series products and solve the preferred material of heat conduction and heat radiation technology.Graphite heat radiation fin heat conduction equably along the horizontal, vertical directions, the laminar structured surface that can adapt to better any product, can effectively play from level, vertical direction the effect of heat conduction and heat radiation.Graphite generally divides native graphite and electrographite, and the thickness of native graphite is thicker, but heat conduction and heat radiation is poor, and the thinner thickness of electrographite, heat conduction and heat radiation is stronger, and both tend to be subject to certain limitation while all separately use.
Summary of the invention
For solving the problem existing in above-mentioned background technology, the object of the present invention is to provide a kind of novel graphite sheet, strengthen to reach natural graphite flakes heat conduction and heat radiation, increase the object of the thickness of electrographite sheet.
For achieving the above object, technical scheme of the present invention is as follows:
Novel graphite sheet, is characterized in that, comprises natural graphite flakes and electrographite sheet, and described natural graphite flakes is pasted mutually with electrographite sheet.
Preferably, described natural graphite flakes is pasted by double faced adhesive tape mutually with electrographite sheet.
Preferably, described natural graphite flakes is pasted by gluing mutually with electrographite sheet.
Pass through technique scheme, novel graphite sheet provided by the invention, pastes natural graphite flakes mutually with electrographite sheet, has so not only strengthened the heat conduction and heat radiation performance of natural graphite flakes, can also increase the thickness of electrographite sheet, in use the scope of application is wider to make this novel graphite sheet.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is the perspective view of the disclosed novel graphite sheet of the embodiment of the present invention one;
Fig. 2 is the perspective view of the disclosed novel graphite sheet of the embodiment of the present invention two.
In figure, number designation represents the title of parts:
1, natural graphite flakes 2, electrographite sheet 3, double faced adhesive tape 4, gluing
Detailed description of the invention
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.
Embodiment mono-:
Novel graphite sheet provided by the invention, as shown in Figure 1, comprises natural graphite flakes 1 and electrographite sheet 2, and natural graphite flakes 1 is pasted by double faced adhesive tape 3 mutually with electrographite sheet 2.
Embodiment bis-:
Novel graphite sheet provided by the invention, as shown in Figure 2, comprises natural graphite flakes 1 and electrographite sheet 2, and natural graphite flakes 1 is pasted by gluing 4 mutually with electrographite sheet 2.
Novel graphite sheet disclosed by the invention, by natural graphite flakes is pasted mutually with electrographite sheet, so not only strengthened the heat conduction and heat radiation performance of natural graphite flakes, can also increase the thickness of electrographite sheet, in use the scope of application is wider to make this novel graphite sheet; Meanwhile, this novel graphite sheet is made simple, with low cost, and practical flexibly.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
