Study of Natural Convection Using Rectangular Finned Heat Sinks with Base and Fins in Vertical Orientation

, , and . International Journal of Innovative Science and Modern Engineering (IJISME), 3 (12): 16-22 (November 2015)

Abstract

Natural convection heat transfer can be enhanced by using heat sink. Experiments will be carried out to investigate the heat transfer in vertical heat sinks in natural convection with considering geometrical similarity approach with constant S/H (fin spacingto fin height) ratio of the fins and even a correlation is obtained between Nusselt number and Rayleigh number. Using this correlation, size of the heat sink can be obtained for various heat loads by interpolation.
