Nano Heat-dissipation Coating
Made by synthesizing unique mineral extracts and other special materials into a nanosolution using state-of-the-art nanotechnology; applied on surfaces of materials.
Mechanism for Nano Heat Dissipation Materials
After the material absorbs so much heat as to achieve heat uniformity through thermal conduction, heat starts to dissipate – converting to radiation heat dissipation until thermal equilibrium occurs. Coatings of the material are in a non-linear form, and nano heat dissipation particles are thus stacked to form nano heat dissipation fins, generating a nano specific surface area many times larger than the physical area. Therefore, our materials are able to demonstrate an increased heat dissipation capability.
