Abstract
The invention discloses a novel graphite heat-conducting device which comprises a graphite matrix, a buffer matrix, a double faced adhesive tape and a thin film. One side of the graphite matrix is pasted to the thin film, and the other side of the graphite matrix is pasted to one side of the double faced adhesive tape. The other side of the double faced adhesive tape is pasted to the buffer matrix. The graphite matrix covers the buffer matrix. By pasting one side of the graphite matrix to the buffer matrix with the double faced adhesive tape, thickness of the integral body is increased. Meanwhile, by elasticity of the buffer matrix itself, resource water caused by superposition of multi-layered graphite flakes can be avoided, and the integral body also can have elasticity so as to play a role in filling the gap between mechanical components. In addition, heat conduction and heat dissipation of the integral body are also raised more remarkably. As the thin film is pasted to the other side of the graphite matrix, the device has insulativity and has wider applicability.

Technical field
The present invention relates to heat conducting and heat radiating device, particularly a kind of novel graphite heat-transfer device that utilizes graphite to realize 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 is as heat conduction and heat radiation 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 not only can be along horizontal heat conduction, and vertically heat conduction is especially used laminar structuredly, not only can make better its surface that is applicable to any product, also can effectively play the effect of heat conduction and heat radiation.But in traditional handicraft, often the mode by some layers of graphite heat radiation fin simple superposition increases its thickness, yet the graphite heat radiation fin of multiple-layer stacked does not only have elasticity, do not have the effect of buffering, also may thereby reduce its heat conduction and heat radiation performance because of the former of multilayer, do not reach effective heat conduction and heat radiation effect between mechanism's part, facts have proved, the number of plies is more, and graphite heat radiation fin is thicker, and its heat conduction and heat radiation performance is poorer; Thereby the thickness that causes graphite heat radiation fin has had very large restriction, and cannot fill up the space between mechanism's part; When using graphite heat radiation fin heat conduction and heat radiation, also need to make it have insulating properties, and the graphite heat radiation fin of multiple-layer stacked does not possess insulating properties, to enterprise, bring very large inconvenience.
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 heat-transfer device, to reach, both increased whole thickness, increased elasticity, make again its insulation, and strengthened the object of its heat conduction and heat radiation.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of novel graphite heat-transfer device, it is characterized in that, comprise graphite matrix, buffering matrix, double faced adhesive tape and film, the one side of described graphite matrix is pasted with described film, the one side of another side and described double faced adhesive tape is pasted, the another side of described double faced adhesive tape and described buffering matrix are pasted, and described graphite matrix is coated on described buffering matrix.
Preferably, described graphite matrix is artificial graphite flake.
Preferably, described buffering matrix is heat conductive silica gel or foam.
Preferably, described graphite matrix is coated on described buffering matrix and forms U-shaped structure or square shape structure.
Pass through technique scheme, a kind of novel graphite heat-transfer device provided by the invention, utilize double faced adhesive tape that the one side of graphite matrix and buffering matrix phase are pasted, its whole thickness is increased, utilize the elasticity of buffering matrix self simultaneously, not only can avoid the wasting of resources causing because of the stack of Multi-layer graphite sheet, can also make its integral body there is elasticity, played the effect of filling up space between mechanism's part, also making its heat conduction and heat radiation performance have more significantly improves, owing to film being pasted on to the another side of graphite matrix, make it have insulating properties, make it have applicability widely.
