1. A magnetic component comprising:
- a first layer of litz-wire windings; and
one or more first cooling tube windings which are metallic and hollow, and configured to extract heat from the corresponding first layer of litz-wire windings, wherein the first layer of litz-wire windings is wound together with a corresponding first cooling tube winding on a common bobbin, and wherein the first layer of litz-wire winding is configured to be spaced apart from the corresponding first cooling tube winding to provide an indirectly-cooled magnetic component spindle assembly, and wherein the first layer of litz-wire windings are disposed outside of the corresponding first cooling tube windings relative to the common bobbin;
a second layer of litz-wire windings, wherein the second layer of litz-wire windings wound together with a second cooling tube winding, the second cooling tube windings being hollow and metallic; and
an insulating layer disposed between the first layer of litz-wire windings and the second layer of litz-wire windings to electrically insulate the first and second layers of litz-wire windings from one another;
wherein the first layer of litz-wire windings and its corresponding first cooling tube winding comprise an identical number of winding turns;
wherein the second layer of litz-wire windings and its corresponding second cooling tube winding comprise an identical number of winding turns.
