Abstract

The present study reviews numerical optimizations of microchannel heat sink with the help of surrogate analysis. The design variables are decided from geometric and shape parameters that influence the performance of the microchannel heat sink. The basic surrogate models are explored with three-dimensional numerical analysis. The single objective optimization is performed taking thermal resistance as objective function and pumping power as constraint while multiobjective optimization is performed taking both thermal resistance and pumping power as objective functions. The sensitivity of the objective function is explored near the optimum point and distribution of the design variables are checked over the Pareto optimal front to analysis the contribution of the design variables to the objective functions. This analysis provides the designer a wide view to economically compromise with design variables considering fabrication methods and available pumping power sources.
