Abstract
The utility model discloses a novel graphite flake which comprises a natural graphite flake and an artificial graphite flake, wherein the natural graphite flake is adhered to the artificial graphite flake through a double-sided adhesive or coated glue. Through the adhesion of the natural graphite flake and the artificial graphite flake, the thermal conductivity and heat dissipation performance of the natural graphite flake are increased, and the thickness of the artificial graphite flake also can be increased, so that the application range of the novel graphite flake is wider in the use process.
Description
Technical field
The utility model relates to heat radiation Heat Conduction Material application, particularly the novel graphite sheet used of a kind of heat conduction of dispelling the heat.
Background technology
In recent years, continuous development along with electronic technology, electronic product is brought in constant renewal in and is regenerated, the size of its work package is more and more littler, speed and the efficient of work are more and more higher, and its caloric value is also increasing, therefore not only require it to be equipped with corresponding heat abstractor, to guarantee that also heat abstractor has stronger heat-sinking capability, with the reliability that guarantees properties of product with prolong its service life.
The graphite heat conducting heat sink material is because its distinctive low-density (with respect to metal species) and high heat conduction and heat radiation coefficient and low thermal resistance become the preferred material that the hyundai electronics series products solves the heat conduction and heat radiation technology.The heat conduction equably along the horizontal, vertical directions of graphite radiating sheet, the effect of heat conduction and heat radiation can be effectively played on the laminar structured surface that can adapt to any product better from level, vertical direction.Graphite generally divides native graphite and electrographite, and the thickness of native graphite is thicker, but heat conduction and heat radiation is relatively poor, and the thinner thickness of electrographite, heat conduction and heat radiation is stronger, and both tend to be subjected to certain limitation when all separately using.
The utility model content
For solving the problem that exists in the above-mentioned background technology, the purpose of this utility model is to provide a kind of novel graphite sheet, to reach the heat conduction and heat radiation that strengthens natural graphite flakes, the purpose that increases the thickness of electrographite sheet.
For achieving the above object, the technical solution of the utility model is as follows:
The novel graphite sheet is characterized in that, comprises natural graphite flakes and electrographite sheet, and described natural graphite flakes is pasted mutually with the electrographite sheet.
Preferably, described natural graphite flakes is pasted by double faced adhesive tape mutually with the electrographite sheet.
Preferably, described natural graphite flakes is pasted by gluing mutually with the electrographite sheet.
Pass through technique scheme, the novel graphite sheet that the utility model provides, natural graphite flakes is pasted mutually with the 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.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the perspective view of the utility model embodiment one disclosed novel graphite sheet;
Fig. 2 is the perspective view of the utility model embodiment two disclosed novel graphite sheets.
Number designation is represented the title of parts among the figure:
1, natural graphite flakes 2, electrographite sheet 3, double faced adhesive tape 4, gluing
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
Embodiment one:
The novel graphite sheet that the utility model provides 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 two:
The novel graphite sheet that the utility model provides 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.
The disclosed novel graphite sheet of the utility model, by natural graphite flakes is pasted mutually with the 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; Simultaneously, this novel graphite sheet is made simple, with low cost, and practical flexibly.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
