“…Some studies tried to use the heat sink as metallic foam to transport the heat by solid conduction and thermal radiation [12]. Aluminium characteristics can be improved per the elaboration and heat treatment [4,7] or by cladding [13]. Rana and others studied the influence of different elements on the microstructure and on the mechanical proprieties of Aluminium such as Copper, Magnesium, Silicon, Titanium, Boron, Chrome, and Zirconium [14].…”

This study aimed to improve the thermal conductivity of the Aluminium 6063 for heat sinks applications used in Central Processing Unit (CPU) of computers. Several studies had used different additional elements for this goal. In this paper, we studied the influence of Titanium and Boron addition on the thermal conductivity of Aluminium 6063. Several casting alloys samples were prepared with different percentage of addition elements and then heat-treated by homogenization and aging treatments. The results showed an important modification in thermal conductivity value per rapport to the reference metal, depending on the element of addition and its percentage. The bigger evolution was by using Boron in small percentage. More than 13% of the improvement was realized in the thermal conductivity with the addition of only 0.05% of Boron.
