Abstract：This work experimentally investigated the heat transfer characteristics of the Graphite and Aluninum alloy pin-fin heat sinks. The results indicated that the cooling capabilities of the Graphite heat sink were 66% and 46% hugher than those of the Aluminum alloy heat sink separately for the free and forced convections. However, the total mass of the Graphite heat sink was only half of the Aluminum alloy heat sink. Furthermore, the cost of the Graphite heat sink is very chape. According to the present results, the total cooling capability of the Graphite heat sink is acceptable, especially for the free convection. Therefore, the Graphite will be the potential material of the heat sinks in the future.
