Abstract
The utility model discloses a graphite heat-conducting apparatus, comprising a graphite layer, a buffer layer, and a glue layer, wherein the graphite layer is wrapped on the buffer layer and combined with the buffer layer into an integral body though the glue layer. The glue layer is utilized to paste the graphite layer and the buffer layer together so as to enable the thickness of the integral apparatus to be increased; and simultaneously, the self elasticity of the material of the buffer layer is employed so as to not only prevent the resource waste due to superposition of multiple layers of graphite flakes, but also enable the integral apparatus to be elastic, have an effect of filling gaps among components, and allow the heat conducing and dissipating properties of the apparatus to be improved substantially.
Description
Technical field
The utility model relates to heat conducting and heat radiating device, particularly a kind of graphite heat conducting 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 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 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 preferred material that the hyundai electronics series products solves the 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, brings very large inconvenience to enterprise.
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 graphite heat conducting device, has both increased whole thickness to reach, and has increased elasticity, has strengthened again 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 graphite heat conducting device is characterized in that, comprises graphite linings, resilient coating and glue-line, and described graphite linings is coated on described resilient coating, and to paste by described glue-line and described resilient coating be an integral body.
Preferably, described graphite linings is artificial graphite flake.
Preferably, described resilient coating is foam or heat conductive silica gel.
Preferably, described glue-line is double faced adhesive tape.
Preferably, described graphite linings is coated on described resilient coating and forms U-shaped structure or square shape structure.
Pass through technique scheme, a kind of graphite heat conducting device that the utility model provides, utilize glue-line that graphite linings and resilient coating are pasted mutually, its whole thickness is increased, utilize simultaneously self elasticity of cushioning layer material, 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, also made its heat conduction and heat radiation performance that more significant raising has been arranged.
