A theoretical study was made to optimize the fin geometry of a helically-grooved, horizontal microfin tube for condensation of R410A. Numerical calculations of overall heat transfer from the vapor flowing inside the microfin tube to the surrounding air were conducted for typical operating conditions of an air-cooled condenser. The previously proposed stratified flow model was applied to the condensation heat transfer inside the tube. The numerical results showed that the effects of the length of flat portion at the fin tip, radius of round corner at the fin tip and the fin half tip angle are small and the effects of the fin height, fin number and helix angle of groove are of significance.
