Abstract
The utility model relates to a kind of high conductive graphite film, comprises release film layer, is provided with high temperature resistant layers of two-sided on described release film layer, and described high temperature resistant layers of two-sided is provided with artificial synthetic graphite linings, in described graphite linings, is provided with protective film; In described high temperature resistant layers of two-sided, be provided with conductive powder.After having adopted above-mentioned high conductive graphite film, can ensure that graphite laminated and graphite edge in graphite guide hotting mask are complete, solved dry linting, come off, the bad phenomenon such as cracked, ensure the heat-conducting effect of graphite heat-conducting fin, and the better difficult drop-off of viscous force between product radiator and pyrotoxin, be not easy to cause graphite substrate cracked, extended the useful life of graphite heat-conducting fin.
Description
Technical field
The utility model relates to cooling electronic component technology, especially relates to a kind of high conductive graphite film.
Background technology
Nowadays electronic equipment tends to small-sized, slim, light, multifunction day by day.The caloric value of chip is increasing, and heat-dissipating space is more and more less, causes electronic product heating serious, occurs that electric weight uses too fast, and automatic shutdown operates malfunctioning, battery life decline, and online business computing is slow, some problems such as potential safety hazard.High-heat conductivity graphite material is plane heat source by heat point source rapid diffusion, allows fast dissipation of heat go out, and allows product and design more have wide space; Because graphite has good plasticity, adding man-hour, can cause graphite film in uneven thickness, thereby cause can not finely posting with radiating element; The bad phenomenon such as graphite film dry linting that also can cause as bad in gum; No matter the general more single side of high conductive graphite membrane structure smoother, in the time being arranged on electronic product, be clamped high conductive graphite film or used clamping device by staff, all very inconvenient, has the potential safety hazard of landing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of high conductive graphite film that dry linting phenomenon can landing that there will not be.
The technical scheme in the invention for solving the technical problem is: a kind of high conductive graphite film; comprise release film layer; on described release film layer, be provided with high temperature resistant layers of two-sided; described high temperature resistant layers of two-sided is provided with artificial synthetic graphite linings, in described graphite linings, is provided with protective film.
Further concrete, in described high temperature resistant layers of two-sided, be provided with conductive powder.
Further concrete, the thickness of described release film layer is 30 μ m～100 μ m.
Further concrete, described protective film is high temperature resistance polyester thin layer.
Further concrete, on the two sides of described high temperature resistant layers of two-sided, be pressure sensitive adhesive.
The beneficial effects of the utility model are: after having adopted above-mentioned high conductive graphite film, can ensure that graphite laminated and graphite edge in graphite guide hotting mask are complete, solved dry linting, come off, the bad phenomenon such as cracked, ensure the heat-conducting effect of graphite heat-conducting fin, and the better difficult drop-off of viscous force between product radiator and pyrotoxin, be not easy to cause graphite substrate cracked, extended the useful life of graphite heat-conducting fin.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, release film layer; 2, high temperature resistant layers of two-sided; 3, graphite linings; 4, protective film.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A high conductive graphite film, comprises release film layer 1 as shown in Figure 1, is provided with high temperature resistant layers of two-sided 2 on described release film layer 1, and described high temperature resistant layers of two-sided 2 is provided with artificial synthetic graphite linings 3, is provided with protective film 4 in described graphite linings 3; In described high temperature resistant layers of two-sided 2, be provided with conductive powder, increased thermal conductivity energy; The thickness of described release film layer 1 is 30 μ m～100 μ m; Described protective film 4 is high temperature resistance polyester thin layer; On the two sides of described high temperature resistant layers of two-sided 2, it is pressure sensitive adhesive.
The utility model can ensure that graphite laminated and the graphite edge in graphite heat-conducting fin is complete, the bad phenomenon such as dry linting are solved, ensure the heat-conducting effect of graphite heat-conducting fin, and the better difficult drop-off of viscous force between product radiator and pyrotoxin, be not easy to cause graphite substrate cracked, extended the useful life of graphite heat-conducting fin.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
