Abstract

An exemplary finned transformer and method of use and fabrication are disclosed that employ an insulation structure comprising a bobbin with finned cooling structures that can improve the thermal conduction of the heat-generating portion of the transformer without use of active cooling loops. The finned bobbins may be employed in conjunction with potted windings. In some embodiments, bobbins with heatsink fins are manufactured with 3D printing or additive manufacturing. In other embodiments, the bobbins with heatsink fins can be cast or manufactured using conventional manufacturing techniques. The cooling structure may be implemented in a dielectric structure situated between the windings of the transformer.
