Carbon compounds have very high heat conductivity. Suffice it to say that the heat conductivity of diamond is 4-5 times greater than the heat conductivity of copper. This property of diamond structure (along with high insulating properties) is used for cooling purposes in electronic devices such as transistors, diodes, graphics cards, etc., implemented using carbon nanotubes.
The use of diamond-like coatings enables a significant improvement in this process by reducing thermal resistance of the surface. At the same time another problem is being solved with this technological solution: protection against oxidation and mechanical damage
