Abstract: With the passage of time size of electronic equipments decreases but power consumption remains constant due to which rise in temperature is the major issue to address in order to increase the life of electronic equipments. Failures of electronic systems due to high temperature have urged engineers to design efficient cooling systems. In natural convection heat transfer the position of vents and heater should be considered as an important variable. They must be placed in order to facilitate the flow rather than obstruct it. Effect of variation of outlet height, outlet area and heater height on mean rise in temperature inside the naturally cooled electronic equipments casing has been studied using Computational Fluid Dynamics (CFD) in this research work. CFD study shows that when heater position is close to outlet, outlet height and area is minimum then maximum mean rise in temperature inside the casing occurs. At the end, computational results have been validated with experimental data available in literature. Computational results have been found to be highly in accordance with experimental values. Percentage difference between computational and experimental values are less than 5%.
