Abstract
The invention discloses a compressible artificial graphite sheet comprising a graphite substrate which is made of artificially synthesized graphite and is 0.1-0.35mm thick. The graphite substrate can be compressed according to various thickness demands, and the thickness of the graphite substrate after compression is 0.01-0.25mm. The graphite sheet not only is wide in application scope, but also can fill a gap between two adjacent working assemblies with the spacing of less than 0.3mm. By the adoption of the graphite sheet, the heat impending phenomenon is avoided, the two adjacent working assemblies are integrated, and the heat conductivity and the heat radiating property are further improved. For a gap between two adjacent working assemblies with the spacing of more than 0.35mm, the heat impending space can be reduced, the heat radiating quantity is increased, and the using property of a product is ensured.
Description
Technical field
The present invention relates to heat conduction and heat radiation material application, particularly compressible electrographite sheet for a kind of heat conduction and heat radiation.
Background technology
In recent years, development along with 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 require it to be equipped with corresponding heat abstractor, also to guarantee that heat abstractor has stronger heat-sinking capability, to guarantee the reliability of properties of product and to extend its useful 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 the preferred material that hyundai electronics series products solves 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.In actual production process, conventionally adopt graphite heat radiation fin that gauge is 0.01-0.1mm to be fitted on the surface of work package of product, reach the object of heat conduction and heat radiation, yet, each product comprises a plurality of work packages, if by each work package surface graphite heat radiation fin of fitting, not only increased the amount of labour of work, also can improve because increasing the quantity of graphite heat radiation fin the production cost of product.Distance between adjacent two work packages is often greater than the thickness of monolithic graphite heat radiation fin, so just make there is certain space between adjacent two work packages, thereby make heat unsettled, be unfavorable for shedding in time of heat, if have above-mentioned space, many places and the unsettled phenomenon of heat in product, the serviceability of product will be affected, even its useful life can be affected.
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 compressible electrographite sheet, to reach the space filled up between work package, avoid or to reduce the unsettled object of heat.
For achieving the above object, technical scheme of the present invention is as follows:
An electrographite sheet, comprises graphite matrix, and described graphite matrix is artificial synthetic graphite, and its gauge is 0.1-0.35mm, and after compression, its gauge is 0.01-0.25mm to described graphite matrix.
Preferably, described graphite matrix is through adjacent two work package compressions.
Preferably, described graphite matrix compresses through rubber roll.
Pass through technique scheme, compressible electrographite sheet provided by the invention, because its gauge is 0.1-0.35mm, and can be according to different-thickness size need to be compressed into the graphite flake that gauge is 0.01-0.25mm, thereby make it can fill up distance to be less than the space between the two adjacent work packages of 0.35mm, avoided the unsettled phenomenon of heat, two adjacent work packages have been formed as one, and then strengthen its heat conduction and heat radiation; For distance, be greater than the space between the two adjacent work packages of 0.35mm, can reduce the unsettled space of heat, increase the heat amount of shedding, guarantee the serviceability of product.

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 compressible electrographite sheet provided by the invention, as shown in Figure 1, comprises graphite matrix 1, graphite matrix 1 is artificial synthetic graphite, its gauge is 0.1-0.35mm, and graphite matrix 1 can compress according to the needs of different-thickness size, and after compression, its gauge is 0.01-0.25mm.
As described in Figure 2, distance between the first work package 2 and the second work package 3 is less than 0.35mm, first the fit one side of the first work package 2 of the one side of graphite matrix 1, then, the second work package 3 arrives its preposition at the effect lower compression graphite matrix 1 of pressure, the another side of graphite matrix 1 one side of the second work package 3 of also fitting, thus, can make the first work package 2 and the second work package 3 shape under the connection of graphite matrix 1 in aggregates, not only filled up the space between two work packages, avoided heat unsettled, also strengthened its whole heat conduction and heat radiation performance.
As described in Figure 3, distance between the 3rd work package 4 and the 4th work package 5 is greater than 0.35mm, gauge is the one side that the one side of the graphite matrix 1 of 0.35mm fits in the 3rd work package 4, the 4th work package 5 is placed in its preposition, compared with prior art, it has reduced the space between graphite matrix 1 and the 4th work package 5, thereby has reduced the unsettled space of heat, has increased the amount of shedding of heat.
A kind of compressible electrographite sheet disclosed by the invention, because its gauge is 0.1-0.35mm, and can be according to different-thickness size need to be compressed into the graphite flake that gauge is 0.01-0.25mm, so not only make the scope of application of this graphite flake wider, also make it can fill up distance and be less than the space between the two adjacent work packages of 0.35mm, avoided the unsettled phenomenon of heat, made two adjacent work packages form an integral body, and then strengthen its heat conduction and heat radiation; For distance, be greater than the space between the two adjacent work packages of 0.35mm, can also reduce the unsettled space of heat, increase the amount of shedding of heat, and then strengthened on the whole the heat conduction and heat radiation performance of product, guarantee the serviceability of product.Meanwhile, in use, this graphite flake of a slice of fitting between adjacent two work packages, can reduce the workload of its work like this, saves production cost.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the present invention.To the multiple modification of these embodiment, will be apparent for those skilled in the art, 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.
