Graphite Heat Pipe

A heat-dissipation component made by wrapping graphite material around a flexible substrate or sealing it in a thin-walled tube. Exploiting the anisotropic thermal conductivity of graphite's layered crystal structure, its in-plane thermal conductivity can reach 1500-1900 W/(m·K), and it is used for cross-region heat conduction in precision structures such as folding-phone hinges.
