Description
Technical field
The technical field of heat conduction and heat radiation material is the utility model is related to, more particularly to a kind of high power device heat dissipation film.
Background technology
With the development of society, the various aspects for being applied to life that various high power devices are more and more extensive, but greatly
Because power is big, its heat energy also increases power device therewith, if good radiating treatment can not be carried out to high power device in time,
The use of high power device can be not only influenceed, and potential safety hazard may occur, so just needing to carry out high power device
Timely radiate, there are many heat abstractors in the market, such as add heat dissipation blower, but the way can increase the body of product
Product, but also certain energy can be consumed, also have paste heat dissipation film, the radiating effect of the heat dissipation film in the market in high power device at present
Unsatisfactory and storage is inconvenient.
Utility model content
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided a kind of heat conduction and heat radiation effect
Fruit is good, pliability is good and high power device heat dissipation film easy to use.
Technical scheme is used by the utility model：The utility model includes basement membrane and graphene heat conduction pulp layer, institute
State and several apertures are uniformly provided with basement membrane, the aperture is less than the counterbore of bottom size, graphene conductive paste for opening size
The bed of material is made up of graphene and slurry solvent, and the graphene heat conduction pulp layer is covered in the surface of the basement membrane and described small
In hole, thermally treated formation secure bond is in the epilamellar graphene heat-conducting layer.
Further, the basement membrane is copper foil.
Further, the lower end of the basement membrane is bonded with oxygen barrier film
Further, the aperture is round table-like counterbore.
Further, the aperture is the counterbore of trapezoidal shape.
The beneficial effects of the utility model are：It is described because the utility model includes basement membrane and graphene heat conduction pulp layer
Several apertures are uniformly provided with basement membrane, the aperture is less than the counterbore of bottom size, graphene heat conduction slurry for opening size
Layer is made up of graphene and slurry solvent, and the graphene heat conduction pulp layer is covered in the surface of the basement membrane and the aperture
Interior, thermally treated formation secure bond make use of graphene heat conduction in the epilamellar graphene heat-conducting layer, the utility model
Property and thermal diffusivity, make the effect of thermal diffusivity of the present utility model and thermal conductivity all fine, and its pliability is good, can crimp storage
Deposit, it is easy to use, further, using the process and the aperture of coating and heat treatment, make the graphene heat-conducting layer firm
It is bonded on the basement membrane.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Embodiment
Such as Fig. 1, in the present embodiment, the utility model includes basement membrane 1 and graphene heat conduction pulp layer, on the basement membrane 1
Several apertures 2 are uniformly provided with, the aperture 2 can be round table-like counterbore, and the aperture 2 is alternatively the counterbore of trapezoidal shape, institute
It can be also the counterbore that other opening sizes are less than bottom size to state aperture 2, and graphene heat conduction pulp layer is by graphene and slurry
Solvent is made, and the graphene heat conduction pulp layer is covered in the surface and the aperture 2 of the basement membrane 1, will by being heat-treated
After slurry solvent removes, secure bond is formed in the graphene heat-conducting layer 3 on the basement membrane 1.
In the present embodiment, the basement membrane 1 is copper foil, and in order to prevent the copper foil to be oxidized, described 1 lower end is bonded with
Oxygen barrier film 4.
The utility model is applied to the technical field of heat conduction and heat radiation material.
Although embodiment of the present utility model is described with practical solution, do not form the utility model is contained
The limitation of justice, for those skilled in the art, according to modification of this specification to its embodiment and the group with other schemes
Conjunction will be apparent from.
