Abstract

A transformer includes a core assembly having a coil, a core with at least a portion extending through the coil, and terminals for providing electrical connection with the transformer. The core assembly is impregnated with a thermally conductive material to form a unitary core mass. An outer coating which is also highly thermally conductive encapsulates the core mass. The outer coating includes a plurality of finned or ribbed surfaces that provide an increased heat transfer area to a surrounding cooling medium such as air.
