CAST COIL ASSEMBLY WITH FINS FOR AN ELECTRICAL TRANSFORMER

摘要

A transformer comprises a core of magnetic permeable material. A first coil assembly extends around the core and includes a first coil of wire encased in a first body of electrical insulating material. The first body is annular with a first inner surface and a first outer surface with a first plurality of fins projecting from the first inner surface. A second coil assembly extends around the first coil assembly and includes a second coil encased in a second body of electrical insulating material. The second body is annular with a second inner surface and a second outer surface with a second plurality of fins projecting from the second outer surface. A third plurality of fins projects from either the first outer surface of the first body or the second inner surface of the second body.
