(under subclass 55) Subject matter wherein a heat exchanging surface is structurally combined with the coil or winding or the core of the inductor, or the coil or winding or the core is especially adapted by its structure to have a heat exchanging surface.
(1) Note. The heat exchanging surface is not limited to heat radiating surfaces but the heat exchange may take place by conduction or convection or a combination of the various types of heat transfer, the essential element required for this subclass being a surface, adapted for heat transfer in intimate relationship with the coil or winding or the core of the inductor.
