Title: LIQUID COOLED MAGNETIC ELEMENT
Abstract:
A toroidal magnetic element. A plurality of coils is arranged in a toroidal configuration. Each coil may be a hollow cylinder, formed by winding a rectangular wire into a roll. The coils alternate with spacers, each of which may be a wedge. The coils may alternate in winding orientation, and the inner end of each coil may be connected, through a connection pin, to the inner end of an adjacent coil. Small gaps are formed between the coils and the wedges, e.g. as a result of each wedge having, on its two faces, a plurality of raised ribs, against which the coils abut. Cooling fluid flows through the gaps to cool the coils.
