This paper reports a result of numerical analysis on the heat transfer enhancement of ribbed PDP heat spreader. Three different ribs are compared in this study. In general, the heat transfer on a vertical plate is enhanced when a rib is attached as the surface area increased and the growth of the boundary layer is interrupted. Cooling performance is evaluated with temperature uniformity and dimensionless temperature difference between surface temperature of heat spreader and ambient temperature. Among the three ribs, V-shaped one showed the best performance.
