Abstract
Convective cooling of a distribution transformer is enhanced by use of magnetic fluid which has a magnetically driven flow pattern in the form of a plurality of vertically stacked magnetic circulation cells with convective heat transfer being enhanced by modifying the configuration of a proximate transformer wall to facilitate the transfer of heat from the magnetic fluid to the wall and then to the ambient air.
