Method and apparatus for cooling an annular inductor

摘要

An inductor cooling method and apparatus is provided, where the inductor comprises both a substantially annular core and an aperture therethrough. The aperture is circumferentially surrounded by the substantially annular core. A container holds a substantially non-conductive coolant and the inductor is immersed in the coolant. Optional spacers hold the inductor away from the container to allow room for coolant circulation.
