고열전도성 재료를 첨가한 서멀그리스의 열전달성능에 관한 연구

The heat dissipation performance of the CPU package greatly affects the performance and lifetime of the CPU. Thermal grease is a kind of TIM, which removes the air layer between the heat spreader and the heat sink during the heat dissipation process of the CPU, so that the heat dissipation smoothly proceeds. However, if thermal grease with low heat transfer performance is used, heat dissipation rate is slowed down. In this study, thermal grease with high performance was prepared by mixing nanoparticles of graphene and metal with high thermal conductivity into thermal grease, and the heat transfer rate was measured. The results showed that the thermal grease mixed with graphene and silver was efficient and the thermal grease with graphene was the most efficient.
