According to experts, the most efficient heat sink design is the one that contains pins or fins. This is because the surface area is increased for the transfer of heat. If you have to design an efficient heat sink, you should consider using copper material. Although it has higher costs it possesses amazingly high thermal conductivity.

The most efficient heat sink design from a geometrical standpoint is one that contains fins or pins to increase the surface area for heat transfer. Copper is one of the best materials to choose for heat sinks as it has a high thermal conductivity. But aluminum is most commonly used due to it’s lower cost and relatively high thermal conductivity.
