Abstract:
1. A magnetic device comprising: a non-toroidal multi-piece magnetic core; a preformed winding into which the magnetic core is inserted; a vessel having a base adapted to conduct heat energy from the magnetic core and the preformed winding; and a cavity in the vessel, the cavity having a first smaller portion having a surface configured to conform with an exterior surface of the magnetic core and a second larger portion having a surface configured to conform with an exterior surface of the preformed winding so that an air gap exists between the cavity and the magnetic core and the winding, the first smaller portion being positioned in the base below the second larger portion so that the magnetic core and the preformed winding are in close proximity to the cavity; and a thermally conductive resin is positioned in the cavity in the air gap between the vessel and the magnetic core and the preformed winding.
