Graphene heat transfer film has excellent thermal conductivity, thermal conductivity is far more than copper, aluminum, iron and other metal conductors, second only to the heat pipe, the essential reason is that in graphene molecules, carbon atoms constitute a hexagonal honeycomb structure, and all Bond, so that each carbon atom has a free electron, and the movement of the free electron enables efficient heat transfer.
It mainly uses the efficient heat transfer ability of graphene, which has a higher thermal conductivity than metals such as copper, aluminum, and iron, second only to heat pipes. However, graphene does not have a working medium and a liquid wick like heat pipes, so It can be made into various shapes according to needs, such as heat transfer plates, heat transfer tubes, and of course, it can also be made into a heat conductive film.
