The utility model discloses a heat dissipation graphite film, which comprises at least two layers of artificial graphite films; the adjacent artificial graphite films are directly bonded together through a graphene slurry layer; the heat dissipation graphite film of the utility model utilizes the graphene slurry layer to bond at least two layers of artificial graphite films together in sequence, and because the thermal resistance of the graphene slurry layer is less, the heat dissipation performance between adjacent artificial graphite films is better; heat dissipation graphite membrane heat dispersion better.
Description
Technical Field
The utility model relates to an improvement of graphite membrane for heat dissipation refers in particular to one kind and utilizes graphite alkene thick liquids layer to adhere at least two-layer artifical graphite membrane together in proper order, the better heat dissipation graphite membrane of heat dispersion.
Background
Electronic components can produce a large amount of heat during operation among the existing communication equipment, if this heat can not in time be dispelled, will influence electronic components's performance and life-span, adopt artifical graphite membrane to dispel the heat usually. In the industry, artificial graphite film is also called synthetic graphite film.
Along with the development of communication technology, the working condition of electronic components is more and more complicated, and the heat that produces along with it is also more and more during operation, and the heat dissipation problem of electronic components can be solved with the artifical graphite film of individual layer originally, later need the heat dissipation problem of 2 above layers of artifical graphite film ability solution.
The existing artificial graphite films with more than 2 layers are generally arranged in a mode of overlapping the artificial graphite films one by one, and adjacent artificial graphite films are firmly adhered by double faced adhesive tape or glue. As shown in fig. 1, since the internal structures of the glue or the double-sided tape and the artificial graphite film are completely different, the heat conduction performance of the glue or the double-sided tape is poor, and the conduction of heat between the adjacent artificial graphite films is relatively blocked, so that the heat dissipation function is affected.
Under the current common condition, the graphene slurry is coated on the surface of the artificial graphite film so as to increase the heat dissipation function of the artificial graphite film.
Therefore, the heat dissipation graphite film which has better heat dissipation performance is developed by sequentially bonding at least two layers of artificial graphite films together by using the graphene slurry layer.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art and providing one kind and utilizing graphite alkene thick liquids layer to adhere at least two-layer artifical graphite membrane together in proper order, the better heat dissipation graphite membrane of heat dispersion.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a heat dissipation graphite film comprises at least two layers of artificial graphite films; and the adjacent artificial graphite films are directly bonded together through the graphene slurry layer.
