Abstract
The utility model discloses a kind of conductive graphite sheet, comprise graphite matrix and film, the size dimension of film is greater than the size dimension of graphite matrix, and film coated, in six faces of graphite matrix, is vacuum state between film and graphite matrix.By by six faces of film coated in graphite matrix, and make between film and graphite matrix in vacuum state, increase associativity therebetween, eliminate the thermal resistance of air in gap, and then improve the performance of graphite matrix at the heat conduction and heat radiation by film place, make it reach the effect of best heat conduction and heat radiation, bring great convenience to enterprise.
Description
Technical field
The utility model relates to heat conduction and heat radiation materials application field, particularly a kind of conductive graphite sheet for heat conduction and heat radiation.
Background technology
In recent years, along with the development of electronic technology, the continuous renewal of electronic product is regenerated, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, its caloric value is also increasing, therefore often adopts graphite heat radiation fin as the preferred material solving electronic product heat conduction and heat radiation.
In prior art, be usually pasted with film in the one side of graphite heat radiation fin, film, in order to protect graphite heat radiation fin, is pasted and is often realized with glue; But, gap is in various degree had between the film sticked with glue and graphite heat radiation fin, usually air is filled with in gap, due to the thermal resistance of air in gap, reduce the heat conduction and heat radiation performance of graphite heat radiation fin at the film place by pasting, make it not reach the effect of best heat conduction and heat radiation, therefore bring very large inconvenience to enterprise.
Utility model content
For solving Problems existing in above-mentioned background technology, the purpose of this utility model is to provide a kind of conductive graphite sheet, to reach the thermal resistance getting rid of air in gap, improves the object of graphite heat radiation fin in the heat conduction and heat radiation performance by film place.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of conductive graphite sheet, comprise graphite matrix and film, the size dimension of described film is greater than the size dimension of described graphite matrix, and described film coated, in six faces of described graphite matrix, is vacuum state between described film and graphite matrix.
Preferably, described graphite matrix is artificial graphite flake.
Pass through technique scheme, the conductive graphite sheet that the utility model provides, by by six faces of film coated in graphite matrix, and make between film and graphite matrix in vacuum state, increase associativity therebetween, eliminate the thermal resistance of air in gap, and then improve the performance of graphite matrix at the heat conduction and heat radiation by film place, make it reach the effect of best heat conduction and heat radiation, bring great convenience to enterprise.
