Comparison of Optimal solutions for Various Fin Shapesof Heat Sinks

Optimal values of the design variables for heat sink with 7 x 7 pin-fins are obtained for two different cross-sectional fin areas by integrating the computational fluid dynamics and mathematical optimization technology. In the pin-fins heat sink, the optimum design variables for fin height (h), fin width (D), and fan-to—heat sink distance (c) can be achieved when the thermal resistance ( ち ) at the junction and the overall pressure drop (^p) are minimized simultaneously. To complete the optimization, the finite volume method for calculating the objective functions and SQP method for solving the constrained non-linear optimization problem are adopted.
