Abstract
Cooling performances for small heat sinks, each of which is composed of small fins and a base, investigated in condition of combined natural and forced air convection, should also be explored in designing the heat sink on a LSI package. An experimental study was performed with respect to natural air convection and forced air convection. Several kinds of small heat sink, which have different base areas, fin intervals and fin heights, are prepared. In natural air convection experiments, the effect of the supplied wattage on the temperature rise of the heat sink was examined for different fin intervals and fin heights. In forced air convection the effect of the air velocity on the temperature rise of the heat sink was examined for different fin intervals and fin heights. From these results, non-dimensional correlations for combined natural and forced air convection to design small heat sinks are presented.
