YAHAM Hi-G thermal grease
Graphene, a mysterious and fashionable material, not only has excellent optical, electrical and mechanical properties, but also has extremely high thermal conductivity (up to 5300W/mK). However, its thickness is only 1/200,000 of the thickness of hair, which cannot be seen or touched. What is the relationship between graphene and lighting? Based on the high thermal conductivity of graphene, Yaham Gaphene Application Technology Center has prepared graphene high conductivity composite material——Hi-G thermal grease, and applied it on lighting lamps, which can enhance the heat dissipation capacity and improve the luminous efficiency.
Hi-G thermal grease fills the graphene into the silicone compound, and the graphene particles and the organic silicon particles contact each other to form an unobstructed mesh-like or chain-like heat conduction network, which greatly reduces the thermal resistance. It can rapidly spread lateral heat in the center of the interface between electronic components and heat sinks, and then conduct heat from the longitudinal direction to the radiator, thereby achieving high efficiency and even thermal dissipation.
Hi - G thermal thermal grease was applied to 200 w lamps.The Junction temperature of the LED reduced to 4 ℃, and the photosynthetic efficiency increases more than 2%.
In addition to the high thermal conductivity values, the two-dimensional geometry of graphene, strong coupling with the matrix material, and low cost make graphene an ideal filler for the interface material.
