Abstract
The utility model discloses an edged graphite flake, which comprises a double faced adhesive tape, a graphite matrix and a glue membrane, one side of the double faced adhesive tape is pasted to one side of the graphite matrix, the other surface of the graphite matrix is pasted to one side of the glue membrane, the size of the double faced adhesive tape and the glue membrane is bigger than the size of the graphite matrix, the size of the double faced adhesive tape is corresponded to the size of the glue membrane, a bound edge is provided for the edges of the double faced adhesive tape and the glue membrane, the thickness of the double faced adhesive tape is 0.005mm-0.01mm, and the thickness of the glue membrane is 0.005mm-0.01mm. by reducing the thickness of the double faced adhesive tape and the glue membrane, the heat radiation and heat conduction effects of the graphite flake can be enhanced, the glue membrane still has the protection effect on the graphite matrix, thereby the heat of the product can be timely and effectively discharged, so that the product performance can be guaranteed, the product service life can be prolonged, and the production cost can be saved.
Description
Technical field
The utility model relates to heat radiation Heat Conduction Material application, and the bound edge graphite flake is used in particularly a kind of heat radiation heat conduction.
Background technology
In recent years, along with the continuous development of electronic technology, electronic product is brought in constant renewal in and is regenerated; The size of its work package is more and more littler; The speed and the efficient of work are increasingly high, 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.
The graphite radiating Heat Conduction Material is because of its distinctive low-density (with respect to metal species) and high heat radiation conductive coefficient and low thermal resistance become the preferred material that the hyundai electronics series products solves heat radiation heat conduction technology.The graphite radiating sheet not only can be along horizontal heat conduction, and vertically heat conduction is especially used laminar structuredly, not only can make its surface that is applicable to any product better, also can effectively play the effect of heat radiation heat conduction.
In the prior art; The size of general double faced adhesive tape that adopts of graphite radiating sheet and glued membrane is all greater than the size of graphite matrix; Edge at double faced adhesive tape and glued membrane forms the bound edge shape like this, so that graphite matrix itself does not leak outside in air, the graphite matrix behind the bound edge has good insulation performance property.The vertical heat radiation heat-conducting effect of graphite radiating sheet receives the influence of the gauge of double faced adhesive tape and glued membrane; Gauge is big more, and its heat radiation heat-conducting effect is poor more, and in the prior art gauge of general double faced adhesive tape and glued membrane all greater than 0.01mm; Such gauge has certain influence to the heat radiation heat-conducting effect of graphite radiating sheet; Heat can not shed timely, will certainly influence performance of products, even can shorten the useful life of product.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of bound edge graphite flake, to reach the purpose of the heat radiation heat-conducting effect that strengthens graphite flake.
For achieving the above object, the technical scheme of the utility model is following:
A kind of bound edge graphite flake; Comprise double faced adhesive tape, graphite matrix and glued membrane, the one side of said double faced adhesive tape is pasted with the one side of said graphite matrix, and the another side of said graphite matrix and the one side of said glued membrane are pasted; The size dimension of said double faced adhesive tape and glued membrane is all greater than the size dimension of said graphite matrix; The edge of said double faced adhesive tape and glued membrane is provided with the bound edge shape, and the gauge of said double faced adhesive tape is less than 0.01mm, and the gauge of said glued membrane is less than 0.01mm.
Preferably, the size dimension of said double faced adhesive tape is corresponding with the size dimension of said glued membrane.
Preferably, the gauge of said double faced adhesive tape can reach 0.005mm.
Preferably, the gauge of said glued membrane can reach 0.005mm.
Through technique scheme, the bound edge graphite flake that the utility model provides is through reducing the gauge of double faced adhesive tape and glued membrane; And then strengthened the heat radiation heat-conducting effect of graphite flake; Glued membrane is not still lost the protective effect to graphite matrix, thereby the heat of product is shed timely and effectively, has better guaranteed performance of products; Prolong the useful life of product, practiced thrift production cost.

Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
A kind of bound edge graphite flake that the utility model provides; Shown in Fig. 1-2, comprise double faced adhesive tape 1, graphite matrix 2 and glued membrane 3, the one side of double faced adhesive tape 1 is pasted with the one side of graphite matrix 2; The one side of the another side of graphite matrix 2 and glued membrane 3 is pasted; The another side of double faced adhesive tape 1 is pasted on the product, so that its effect of graphite flake performance, 3 pairs of graphite matrixs 2 of glued membrane play a protective role; The size dimension of double faced adhesive tape 1 and glued membrane 3 is all greater than the size dimension of graphite matrix 2; The size dimension of double faced adhesive tape 1 is corresponding with the size dimension of glued membrane 3; The edge of double faced adhesive tape 1 and glued membrane 3 is provided with the bound edge shape; Can effectively wrap up graphite matrix 2, graphite matrix 2 is not leaked outside in air, guarantee its insulating properties; The gauge of double faced adhesive tape 1 is 0.005mm-0.01mm, and the gauge of glued membrane 3 is 0.005mm-0.01mm.
The disclosed a kind of bound edge graphite flake of the utility model; Through reducing the gauge of double faced adhesive tape and glued membrane, and then strengthened the heat radiation heat-conducting effect of graphite flake, glued membrane is not still lost the protective effect to graphite matrix; Thereby the heat of product is shed timely and effectively; Better guarantee performance of products, prolonged the useful life of product, practiced thrift production cost.
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 conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
