Abstract
In this work, the thermal analysis of heat sinks is proposed using an analytical approach. The mathematical modeling is composed by a three-dimensional base and two-dimensional fins. The oncoming heat flux from a heated chip attached at the bottom of the base needs to be cooled in order to ensure its good performance and long service life. For this reason, fins coupled at the top of base of the heat sink are responsible for increasing the heat transfer and cool the system. Also at the top of the base, air is flowing between fins contributing for the temperature's reduction of the system. The Classical Integral Transform Technique is applied for solving the formulation of fins and the base. The results show the more fins attached to the base, the lower is the temperature of the base in the heat sink.
