Abstract
This work proposes an analytical approach of the heat transfer analysis in heat sinks applied on cooling electronic components of solar panels. On the bottom of the base of the heat sink, the presence of the oncoming heat flux from a heaten solid-state electronic needs to have its heat dissipated, in order to ensure a profitable performance of the solar panel. Since the thickness of the base is small compared to other dimensions of the heat sink, a partial lumping approach in z-direction is performed and the final mathematical formulation is two dimensional, considering also the heat flux source term. In order to obtain the final solution, the Classical Integral Transform Technique is applied and four diferent cases are presented: the heat sink without any fin, with one, two fins and with four fins. The achieved results are compared by the increase of the heat dissipation affecting the final temperature of the heat sink.
