Graphene is a single layer of carbon atoms, which can be obtained from graphite. Graphite is natural. It is dug out of the mine. In essence, it is formed by stacking many layers of graphene. They all have heat conduction and heat dissipation performance. There is no difference in the field of application, but they are different in their own structure.

The reason why the graphite sheet needs to be edged

Power battery is the ;heart; of new energy vehicles. The battery pack of new energy vehicle needs to work in harsh environment for a long time, which will shorten the service life of battery. The uneven distribution of temperature field in the battery box will cause the performance imbalance of each battery module. The thermal mon

The heat dissipation graphite film plays a role of heat insulation on PCB to some extent. On the one hand, it can even the heat and alleviate the local overheating inside the mobile phone. At the same time, it quickly diffuses the heat before it is transferred to the shell, so that the user does not feel too hot.

Vapor chamber works on the same principle as heat pipe. They have a vacuum sealed metal shell, an internal core structure attached to the inner wall, and use capillary action to move the liquid around the system. In most cases, the performance of vapor chamber is better than that of heat pipe.
