Abstract |
Micro fin performance analysis of extended surfaces (fins) under free convection in order to determine the enhancement in the heat transfer rate. The correspondences between fins geometries and heat transfer coefficients, that problem of free or natural convection heat transfer rate in a micro fin array heat sink is CFD analysis. The studies have shown that the convection heat transfer rate from fin arrays depends on all geometric parameter, fin material, fin height, fin spacing, fin thickness and base to ambient temperature difference. Heat transfer rate increases with different types of micro fins such as rectangular plat flat fin, triangular wavy flat fins. Computational Fluid Dynamics (CFD) analysis was conducted to investigate the heat transfer performance of triangular wavy fins and result was compared with that of flat plate rectangular fins of same configuration. The heat sinks are made of 5 cm x 5 cm squared silicon wafer and the fin height ranges between 0.6 mm and 0.8 mm, the spacing between 0.2 mm and0.8 mm and the thickness between 0.2 and 0.8 mm. The result shows better heat transfer performance of flat plate fin and triangular wavy fins studies conducted by changing the geometric parameters fins like fin height, fin spacing and thickness etc. |
