Abstract
This paper reports a result of numerical heat transfer analysis for heat spreader with various ribs. Four 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 increases, and the growth of the boundary layer is interrupted. However, for a low flow less than 0.1m/s, it is observed that the heat transfer is sensitive to the height of a rib: it decreases as the height increases. Among the four ribs, the H-shaped rib showed better performance than other ribs.
