Two-dimensional natural convection heat transfer in a rectangular cell enclosed with horizontal plate-fins and hot and cold surfaces which were vertical and isothermal, was analyzed numerically by the finite difference method. The analytical results of the isotherms in the cell were in good agreement with the experimental results obtained by the interferometric technique. The calculations were carried out for the Rayleigh number of 10^5-10^7, varying the aspect ratio, Prandtl number, and the fin parameter, which was determined from the thickness and thermal conductivity of the fins. The effects of these four parameters on both the average Nusselt numbers on the hot surface and the fin surface and on the non-dimensional heat quantity transferred from the hot surface to the fins were clarified.
