Electronic devices, e.g. projector, high power semiconductors devices, LED, chips, etc., require efficient cooling methods for dissipation of heat in a limited region. These devices should be maintained at low and acceptable temperature for their efficient working. So the heat dissipation from these devices becomes critical factor. One of the solutions to remove the heat from such devices is to use heat sink in natural or forced convection. This study the performance of radial heat sink under forced convection is investigated. The different parameters which are considered for the study of radial heat sink are number of fins, height of the fin, length of the fin, velocity of air and the heat input. To investigate the thermal performance under forced convection of a radial heat sink different models are designed and manufactured using the Taguchi method of design of experiments. The experiments are performed and the data collected is analyzed using analysis of variance (ANOVA) to observe the effect of various parameters on the performance of the radial heat sink. The effects of various parameters have been experimentally investigated and the optimum values are found out for radial heat sink under forced convection
