Complete eliminates heat, how to achieve the effect that heat radiation and heat transfer combine, is a problem to be solved.
Utility model content
The main purpose of the utility model is to overcome above-mentioned shortcomings, provide a kind of temperature uniforming heat radiation piece.
The technical solution of the utility model are as follows: a kind of temperature uniforming heat radiation piece, including metal-based layer, the metal-based layer upper surface
For radiating surface, the radiating surface is corrugated surface, and the radiating surface is coated with several layers graphene layer, the metal-based layer lower surface
For shiny surface.
Further, the shape of the graphene layer and the shape of radiating surface are adapted.
Further, the thickness of each graphene layer is identical.
Further, the thickness of the graphene layer and metal-based layer ratio is 1:200.
Further, the metal-based layer is silver foil, copper foil or aluminum alloy sheet.
Compared with prior art, the utility model has the advantages that
1, in temperature uniforming heat radiation piece provided by the utility model, the thermal coefficient of the graphene layer of radiating surface coating is reachable
5300W/mK is the several times of the metal materials such as silver, copper, gold, aluminium, since graphene has the heating conduction combined and heat
Radiance substantially increases the heat dissipation effect of cooling fin, can reduce to significant effective the surface temperature of thermal objects, thus
It solves electronic product heat dissipation problem, especially mobile phone cpu chip plane and is covered with graphite linings, heat dissipation effect is limited, body core
Piece spot temperature is very high, seriously affects the electronic product speed of service, card machine, crash phenomenon occurs；Pass through metal-based layer and graphite
Alkene layer combines, and can reach the effect of fabulous heat transfer heat dissipation, which is used for electronic product, can be promptly
Heat biography is scattered, then heat is radiate by way of infrared waves.
2, in temperature uniforming heat radiation piece provided by the utility model, radiating surface is corrugated surface, has bigger surface area, is conducive to
Heat dissipation.
3, temperature uniforming heat radiation piece provided by the utility model, structure is simple, stablizes, and heat-sinking capability is strong, can be applied to space it is small,
On electronic product light-weight, heat is high, such as game machine, printer, engraving machine.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the temperature uniforming heat radiation piece of the utility model；
Description of symbols: 1 is metal-based layer, and 11 be radiating surface, and 12 be graphene layer；
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It is easier to be readily appreciated by one skilled in the art with feature, to make apparent define to the protection scope of the utility model.
Embodiment 1
Fig. 1 gives the structural schematic diagram of the temperature uniforming heat radiation piece in the present embodiment 1, in conjunction with reference Fig. 1, a kind of temperature uniforming heat radiation
Piece, including metal-based layer 1, wherein 1 upper surface of metal-based layer is radiating surface 11, and radiating surface 11 is corrugated surface, and radiating surface 11 coats
There is several layers graphene layer 12, the thickness of each graphene layer 12 is identical, and 1 lower surface of metal-based layer is shiny surface.
Wherein, the thickness of graphene layer 12 and metal-based layer 1 ratio is 1:200.
The present embodiment is preferred, and the shape of graphene layer 12 is corrugated compatible with the shape of radiating surface 11, so that
Contact area becomes larger, better heat-radiation effect.
The present embodiment is preferred, and metal-based layer 1 uses aluminum alloy material, and aluminium die-casting material is substantially better than on heat dissipation performance
Or ferrous material.
The present embodiment prepares graphene slurry using water as solvent, and compared with other organic solvents, cost is relatively low, is not present
Inflammable and explosive security risk, it is often more important that health environment-friendly is safe from harm to the health and ecological environment of operator,
Also have the advantages that more frivolous, easy processing, wear resistant corrosion resistant, cost are lower, the service life is longer；It is being dissipated by the way of spraying
Heat sink surface processing graphite alkene layer, coating exquisiteness, smooth, saving raw material, production efficiency and operability height, is suitable for industry certainly
Dynamic metaplasia produces.The thickness of graphene layer can be controlled in 0.1-2 μm, using the special molecular structure of graphene, converts heat energy into
Infrared ray, and then by heat away, greatly improve the radiating efficiency of cooling fin.
Temperature uniforming heat radiation piece overall structure setting provided in this embodiment rationally, in the radiating surface of cooling fin coats several layers stone
Black alkene layer, and the thickness of graphene layer is at 0.1-2 μm, so that whole temperature uniforming heat radiation piece has excellent heat dissipation performance and hot spoke
Performance is penetrated, than commonly comparing without the cooling fin of graphene coated layer, temperature can decline 7-12 degrees Celsius, in addition, radiating surface is adopted
With corrugated surface, increasing heat radiation area further increases heat dissipation effect, meets actual operation requirements.
Temperature uniforming heat radiation piece provided in this embodiment, structure is simple, stablizes, and heat-sinking capability is strong, can be applied to that space is small, weight
Gently, on the high electronic product of heat, such as game machine, printer, engraving machine.
The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
