ABSTRACT:
High frequency electrical coils are commonly made out of Litz wire. If the coil is baked and an aqueous phenol solution is pumped through a nylon tube making up the structural core of the Litz wire, the tube will be dissolved out, thereby yielding an unobstructed opening through which a cooling fluid may be pumped. The resultant coil has a vastly improved heat conduction and can tolerate substantially higher currents.
