A Comparison of Fin Geometries for Heatsinks in Laminar Forced Convection; Part I-Round, Elliptical, and Plate Fins in Staggered and In-Line Configurations

摘要

In this study, the heat transfer performance of various commonly used fin geometries is compared. Realistic, manufacturable geom- etries are considered for minimizing thermal resistance at moderate laminar air velocities and pressure gradients. These consist of plate fins or pin fins, which can be round, elliptical, or square. The plate fins can be continuous (parallel plates) or staggered. The pin fins can be inline or staggered arrays. In order to compare these various geometries, a set of standard conditions was required.
