The asymmetry of artificial thermal conductive graphite sheet material is always light and thin in the thickness direction, which has the same thermal conductivity as regular thermal conductive interface material and even higher thermal conductivity coefficient. On the plane, it has much better thermal conductivity than metal, and can quickly spread and take away the heat to achieve the effect of heat sharing. This is undoubtedly a magic weapon to cool the CPU for tablet computers. At the same time, the lamellar structure can be well adapted to any surface, and the heat source temperature can be diffused when connecting the heat source, so as to avoid the high temperature inside the electronic products caused by too small heat dissipation area. The thermal conductive graphite sheet can improve the comprehensive performance of the consumer electronic products while conducting heat.
