A bottom of the adhesive layer is covered with a release layer. The heat dissipation layer is a carbon nano-tube layer. Insulation heat dissipation wood carries out knock off and die cutting and can be attached to any plane or bending surface. Good heat conduction and heat dissipation performance is possessed. The film can be widely applied in electronic products, such as a mobile phone, a flat computer, a LCD screen and the like.
Description
Technical field
The utility model relates to a kind of high efficiency composition heat dissipation film.
Background technology
Rapidly, terminal electronic product producer is by the modes such as compressed products volume of constantly the enhancing product performance electronic market of trying to win the champion at present electron trade development.Interiors of products electronic component relative density increases, and takes up room and dwindles.Cause electronic product in running, electronic component temperature is assembled and cannot be shed.Thereby the operation usefulness that reduces product, even may there is potential safety hazard in too high temperature.
In order to solve electronic product element, because causing the too high product that affects of electronic product internal temperature, the too high heat producing that generates heat moves usefulness, a lot of electronic products have been selected to dispel the heat with graphite flake, but the easy dry linting of graphite, has brought certain hidden danger to electronic product.
Than aluminium, there are higher rigidity, buckling strength with graphite-phase.Conductive coefficient relative and graphite vertical direction is higher, and heat conductivility is better, but the conductive coefficient of horizontal direction is relative and graphite differs greatly.Be not suitable for serving as direct heat sink material in the highdensity electronic product of element.
Therefore the common way of industry is after graphite and aluminium laminating, to act on electronic product inside, to improve the thermal conductivity of such material, but because there is the existence of adhesive layer to have heat between graphite flake and metal level, transmit discontinuous phenomenon, and then reduce the thermal conductivity of whole material.
Summary of the invention
The utility model proposes a kind of composite heat dissipation material, there is excellent heat conductivility, can be electronic unit heat dissipation interface is provided.
For realizing this purpose, the structure that the utility model adopts is: a kind of high efficiency composition heat dissipation film, comprise base material, described base material is to be the aluminium foil that plane is extended, described base material one side is evenly coated with heat dissipating layer, another side is evenly coated with adhesive layer, on described adhesive layer, is coated with release layer, and described heat dissipating layer is carbon nanotube layer.
Described adhesive layer is heat conduction glue-line.
Thickness >=7 μ the m of described aluminium foil.
Thickness >=5 μ the m of described carbon nanotube layer.
Thickness >=18 μ the m of described aluminium foil.
The thickness of described carbon nanotube layer is 5 μ m～25 μ m.
Its beneficial effect is: this insulating radiation wood cross cutting of knocking off, can be attached at any plane or curved surface, and there is good heat conduction and heat radiation performance, can be widely used in the electronic products such as mobile phone, flat board, LCD screen.
Accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the utility model structural representation.
