This paper evaluates the interaction between three design variables of a conventional extruded heat sink used for automotive audio systems in a passive convection environment. A 3-level Design of Experimentation (DOE) methodology, with a center point design, is utilized to quantify the non-linear behavior and the interaction effects between three design variables of the heat sink. A full factorial analysis of 27 CAE runs is employed to begin the DOE analysis. A second order non-linear response function is developed, using an estimated regression coefficient, that's used to optimize the heat sink design. The second-order quadratic model that includes the 2-way linear interactions between design variables is proven to be the model of choice that can characterizes the heat sink temperature more effectively and accurately.
