The thermal conductivity of flake graphite is mainly reflected in the graphite heat sinks produced and processed. The heat dissipation principle of graphite heat dissipation technology is a typical thermal management system. The important function of the radiator is to create the maximum effective surface area on which the heat is transferred and taken away by external cooling media. Graphite radiator can transfer heat effectively by distributing heat evenly in two-dimensional plane to ensure that the components work at the temperature they are subjected to. It greatly reduces the heat dissipation and improves the stability of the product.
