The thermal problems of most electronic components have been solved in recent year. Passive cooling of electronic component by natural convection heat transfer has major advantage of no vibration, least expensive and most authentic method of heat rejection. The parameters frequently considered are: Nusslet Number, Rayleigh number and the distance between heat sources. The present work discuss about natural convection in a vertical channel with single heat source.. In this work two experiments were conducted. viz. Natural convection in a two parallel vertical plate and natural convection in a vertical channel with single heat source. The experimental setup has been designed and fabricated. In the first case, experimentally the Nusslet Number and Rayleigh Number were calculated and compared with the value available from correlation and found to be in reasonably good agreement. In the second case, experimentally obtain an optimum location for a single heat source in vertical channel and correlation is developed for nusslet number in terms of Rayleigh number and aspect ratio.
