简介
Thermal resistance and pumping power are two key metrics to evaluate the performance of microchannel heat sinks. To reach their better performance, porous medium can serve as an appropriate alternative to conventional solid rib due to its unique geometric architecture. In this work, the performance of a selected porous-ribs microchannel heat sink proposed previously is significantly improved through a 3D fluid-solid conjugated model coupled with a multi-objective and multi-parameter genetic algorithm optimization method. The optimal design and operation parameters are achieved under a constant volumetric flow rate. The Pareto-optimal front presents that the MCHS can reach a minimum thermal resistance of 0.06306 K/W with pumping power of 0.38317 W, and a minimum pumping power of 0.00171 W with thermal resistance of 0.37755 K/W. The optimization finds the optimal thermal resistance and …
