It is increasingly becoming a difficult problem urgently to be resolved hurrily.Existing market portioned product carries out heat conduction and heat radiation, especially copper and aluminium by metal class, though
The thermal conductivity factor of right copper is high, but weight is big, oxidizable etc. limits its application, and the thermal conductivity factor of aluminium is not high, is difficult to
Meet the demand to heat conduction and heat radiation for the existing product.And Graphene heat dissipation film, it is a kind of brand-new heat conduction and heat radiation material, specific surface area
2630m2/g；Carrier mobility is the highest: 200,000 cm under room temperature2/ Vs (100 times of silicon), theoretical 1,000,000 cm2/Vs；Current density
Patience is maximum: be expected to reach 200,000,000 A/cm2；Maximum intensity is the hardest: breakdown strength 42N/m, and Young's modulus is suitable with diamond；
Thermal conductivity is the highest: 3000-5000W/mK, is more than 13 times of copper.As can be seen here, graphite is compared with traditional heat-dissipating material, and it is had
Some quick conductive characteristics and quick heat radiating characteristic will make Graphene become splendid heat sink material.
The main material of Graphene heat dissipation film is native graphite, has the crystal grain orientation of uniqueness, uniformly leads along both direction
Heat, laminar structured being well adapted for, improves the property of consumer electronics product at any surface while shielding thermal source and assembly
Can, also providing in terms of thickness while heat radiation and be thermally isolated, typical thermal management system is by outside cooling device, heat radiation
Device and heating power cross section composition, and the critical function of heat dissipation film be create to effective surface area, heating power on this surface
Be transferred and have extraneous cooling media to take away, graphite radiating film be through by even heat be distributed on two dimensional surface thus
Effectively heat is shifted, it is ensured that assembly works at a temperature of being born.But existing Graphene heat dissipation film is due to gum
With the thickness reason of notacoria, the radiating effect in small space is not fine.
