Abstract
The utility model discloses an insulation heat dissipation film. The film comprises a base material. The base material is a polyester film layer. One surface of the base material is uniformly coated with a heat dissipation layer and the other surface is uniformly coated with an adhesive layer. A release layer covers on a bottom of the adhesive layer. The heat dissipation layer is a carbon nanotube layer. An insulation heat dissipation wood knocks off and carries out die cutting. The film can be stuck on any plane or bending surface, possesses good heat conduction and heat dissipation performance and can be widely applied in electronic products of a mobile phone, a flat computer, a LCD screen and the like.
Description
Technical field
The utility model relates to a kind of insulating radiation film.
Background technology
High speed development along with electronic industry, modern society's electronic installation is more and more universal, as more and more in household electronic device, industrial electronic device and information communication devices such as PC, mobile phone, server, GPS navigation devices, function is more and more and powerful.Electronic apparatus functions gets more and more and from strength to strength, its inside chip or electronic module are also more and more accordingly, and the speed of service is more and more faster.Inside chip or the electronic module speed of service are more and more faster, and the parts of the high temperature of generation are also more and more.Add short, thin, light, littleization of electronic installation, so that in minimum space, to place considerable chip like this or electronic module, short thin light little space cannot or be difficult to by fan is set, heat be conducted merely, and chip or electronic module at high temperature can reduce service behaviour, shorten working life.Under the development trend of such electronic industry, the thermal energy conduction producing in the time of certainly will will having heat conducting material handle to result from chip or electronic module work out.But the heat at high-temperature component place conventionally with adhesive tape gluing, is difficult to diversion but glue-line exists the inhomogeneous discontinuous problem of heat conduction down to high-temperature component place heat build-up between adhesive tape and heat sink material, causes electronic product radiating not in time, affects its serviceability.
Summary of the invention
The utility model relates to a kind of insulating radiation film, has good thermal conductivity, can be electronic unit heat dissipation interface is provided.
For realizing this purpose, the structure that the utility model adopts is: a kind of insulating radiation film, comprise base material, described base material is to be the polyester film sheet material 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 >=12 μ the m of described polyester film sheet material.
Thickness >=5 μ the m of described carbon nanotube layer.
The thickness of described carbon nanotube layer is 8 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.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing), unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
Insulating radiation film as shown in Figure 1, comprise base material 1, what base material 1 adopted is to be the polyester film sheet material that plane is extended, the thickness >=12 μ m of polyester film sheet material, polyester film has good insulation property and heat conductivility, and has higher tensile strength and rigidity.The one side of base material 1 is evenly coated with heat dissipating layer 2, heat dissipating layer 2 is carbon nanotube layer, the thickness of carbon nanotube layer is 8 μ m～25 μ m, carbon nano-tube has good insulation property and horizontal heat conductivility, heat on base material 1 can be dispersed in to the surface of carbon nanotube layer, and heat diversion is extremely extraneous, to play the function of level heat radiation, made up polyester film can only insulate thermal resistance and problem that can not heat conduction and heat radiation, laminated polyester film has made up again the problem of carbon nano-tube tensile strength and rigidity deficiency simultaneously.The another side of base material 1 is evenly coated with adhesive layer 3, is coated with one deck release layer 4 on adhesive layer 3, and described adhesive layer 3 is heat conduction glue-line, the heat on electronic component can be conducted to base material 1.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
