摘要: Abstract Constructal optimization of the whole cylindrical pin-fin heat sinks (PFHS) is performed by finite volume method (FVM). Maximum dimensionless transfer rate (MDHTR) taken as objective for fixed total sink and fin-material volume, pressure drop used to evaluate hydraulic performance system. Variation (DHTR) its corresponding along diameter studied, influences fraction fluid velocity on results are analyzed, flow field temperature distribution PFHS shown. The show that there exists an optimal which corresponds number pin fins makes DHTR maximized when shape fixed, MDHTR constructs different fraction; aspect ratio maximization. sensitivity higher than does, but with respect PFHS, higher. this paper can provide theoretical support design PFHS.
