Technical field
The utility model 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, with the reliability that guarantees properties of product with extend its useful life.
Graphite is as the 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 hyundai electronics series products, solves the preferred material of 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 can't fill up the space between mechanism's part; When using the 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, brings very large inconvenience.
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 heat-transfer device, to reach, has both increased whole thickness, has increased elasticity, makes again its insulation, and has strengthened the purpose of its heat conduction and heat radiation.
For achieving the above object, the technical solution of the utility model 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 that the utility model provides, utilize double faced adhesive tape that the one side of graphite matrix and buffering matrix phase are pasted, its whole thickness is increased, utilize simultaneously the elasticity of buffering matrix self, not only can avoid the wasting of resources that causes because of the stack of Multi-layer graphite sheet, can also make its integral body have elasticity, played the effect of filling up space between mechanism's part, its heat conduction and heat radiation performance has been had more significantly to be improved, owing to film being pasted on the another side of graphite matrix, make it have insulating properties, make it have applicability widely.
