The aim of this study is to analyze a single component heat sink design numerically and analytically. The analysis included various modeling assumptions: lumped parameter; one dimensional and two dimensional models. It is shown that the lumped model for the considered problem is capable to accurately predict the steady state temperature of the heat sink with a small discrepancy at the center of the heat sink. Some results are presented graphically for various parameters to show their effect on the steady state temperature of the heat sink including power input; convective heat transfer coefficient; ambient temperature; thickness of the heat sink and the shape of the cross section of the heat sink (circular, ellipsoidal, squared). A few particular applications include single solar cell under high concentration; thermoelectric cooling device and/or high-power led. The findings of the research are twofold: educational and the derived formulae serve as a quick estimate tool to predict the effect of the various parameters on the heat sink temperature and thus aids to estimate the thermodynamic efficiency of the system.
