Abstract
The utility model relates to a graphite radiation film applied to an intelligent mobile phone and a tablet computer. The graphite radiation film comprises a raw material carbon film. A layer of insulation film is on the raw material carbon film. A layer of heat conduction double-sided adhesive is at the bottom of the raw material carbon film. The graphite radiation film provided by the utility model has obvious effects of heat conduction and heat radiation, and can be widely used in the intelligent mobile phone, the tablet computer and other industries.
Description
Technical field
The utility model relates to a kind of heat conduction thin-film material, specifically the graphite radiating film used of a kind of smart mobile phone and panel computer.
Background technology
Along with developing rapidly of microelectronics integrated technology and high density printed board packaging technology, packaging density improves rapidly, and electronic component, thousands of times of ground of logical circuit volume dwindle, and electronic instrument and equipment develop towards light, thin, short, little direction day by day.Under the high-frequency work frequency, semiconductor working heat environment is mobile rapidly to the high temperature direction, at this moment, heat run-up, increase that electronic devices and components produce, under the environment for use temperature, make electronic devices and components still can high reliability the ground operate as normal, in time heat-sinking capability becomes the critical limitation in its useful life factor that influences.Be to ensure the components and parts operational reliabilitys, need to use the material of excellent combination properties such as high reliability, high thermal conductivity, rapidly, the heat that in time heater element gathered passes and dispel the heat away guarantee electronic equipment operate as normal.
Along with science and technology development, panel computer, smart mobile phone, high-end digital product etc. all come into the market in enormous quantities.The heat sink material that it is traditional and structure can not satisfy the heat radiation requirement far away.
The utility model content
Technical problem to be solved: the utility model purpose provides the graphite radiating film that a kind of smart mobile phone and panel computer are used, its radiating effect excellence.
Technical scheme: the graphite radiating film that a kind of smart mobile phone and panel computer are used, comprise the raw material carbon film, above the described raw material carbon film one deck dielectric film is arranged, there is one deck bond plies raw material carbon film bottom surface.
The utility model is all right: described insulator film thickness is 0.01mm.Described bond plies thickness is 0.01mm.
The utility model effect is: the graphite radiating film is a kind of novel heat conduction and heat radiation material, and the effect of its heat conduction and heat radiation is very tangible, can be widely used in smart mobile phone, in the industries such as panel computer.
The graphite radiating membrane structure presents sheet, and heat conduction and heat radiation mainly is along level and vertical direction Homogeneouslly-radiating.Allow heat be communicated to better on the external world or the miscellaneous part.The critical function of graphite radiating film is to create maximum effective surface area, and heating power is transferred and has extraneous cooling media to take away on this surface.Thereby the graphite radiating film of panel computer, smart mobile phone is exactly by being evenly distributed in heat two dimensional surface effectively with transfer of heat.One deck dielectric film is arranged above the raw material carbon film, and there is one deck bond plies the bottom surface, and it is convenient to use when installing, quick, good heat dissipation effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: raw material carbon film 1, dielectric film 2, bond plies 3.
Embodiment
See Fig. 1, the graphite radiating film that a kind of smart mobile phone and panel computer are used comprises raw material carbon film 1, above the described raw material carbon film 1 one deck dielectric film 2 is arranged, and there is one deck bond plies 3 raw material carbon film 1 bottom surface.
The chemical composition of heat conductivity graphite material mainly is single carbon, be a kind of native element mineral. the film macromolecular compound can be by obtaining the graphitization film under the chemical method HTHP, raw material carbon film described in the utility model is exactly this graphitization film.
Dielectric film is the film that can guarantee the good electrical insulating properties.This film should have very high resistivity and disruptive field intensity, and that the electronic structure characteristics are energy gaps is big.In order to be used for high-frequency insulation, also require material to have low dielectric loss.Dielectric film has inorganic and organic two classes.Inorganic insulator is commonly referred to dielectric, and commonly used have silica, silicon nitride, aluminium oxide, an aluminium nitride; Organic insulation membrane material commonly used has polyimides, polyethylene, polyvinylidene fluoride, polytetrafluoroethylene.No matter be inorganic or organic insulator, generally all has the ability that under External Electrical Field, polarizes.During as electrical insulating film, wish that its dielectric constant is low, to reduce dielectric loss.
It is insulating film material that the utility model adopts polyethylene.
Bond plies is known materials, fills the thermal conductive ceramic powder by the acryl polymer, is composited with organic silicon adhesive.Have the characteristic of high heat conduction and insulation, and have flexibility, compressibility, docile property, strong viscosity.The adaptive temperature scope is big, can fill up irregular surface, and energy close and firm ground applying thermal source device and fin conduct heat fast.
The utility model only limits to these examples absolutely not.The above only is the utility model embodiment preferably, only is used for describing the utility model, can not be interpreted as the restriction to scope of the present utility model.Should be pointed out that all any modifications of within spirit of the present utility model and principle, making, be equal to replacement and improvement etc., all should be included within the protection range of the present utility model.
