摘要: The optimal thermal design issue of a forced aircooled heat sink to obtain satisfied performance indices such as resistance, pressure drop, geometry, total weight and cost is great practical value for the stable safe operations power electronic equipment. This paper formulates this firstly typical constrained optimization problem by considering entropy generation rate objective function subjecting some engineering constraints, then presents novel method air-cooled combining basic idea minimization (EGM) an effective evolutionary algorithm called population extremal (CPEO). effectiveness proposed demonstrated comparing different algorithms based methods in terms statistical best rate, geometry weight.
