Electric and electronic panels are often cooled by free convection. In some cases the current is periodic due to on-off control mechanisms or due to partially rectified a-c voltage. Periodic heat input of a single vertical plate with no edges was investigated by Menold and Yang and Schetz and Eichhorn. Others have studied the effect on boundary layer development, also on a single plate. The present note address the fully developed convection between two periodically heated parallel plates. Fully developed fow, occurring at small Rayleigh numbers is becoming more common due to the trend in miniaturization of the panels.
