Abstract :Computational Fluid Dynamic (CFD) is used to analyse characteristics of plate fin heat sinks ,the correlation between heat sink and fluid by multivariate linear regression is built . Specific expression of thermal resistance and the rate of ent ropy generation are offered. The multi parameter const raint optimization procedure ( Genetic Algorithms) based on the minimization of ent ropy generation resulting f rom viscous fluid effect s and heat t ransfer are carried out on the plate fin heat sinks ,optimization result s coincide with previous analysis and related document s.
