Abstract
A fluid-cooled magnetic element. A plurality of coils is arranged in a non-toroidal configuration. Each coil may be a hollow cylinder, formed by winding a rectangular wire into a roll. The coils alternate with planer spacers. 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 spacers, e.g. as a result of each spacer 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.
Claims22
A fluid-cooled magnetic element, comprising:
- a first electrically conductive coil, having a first annular surface and a second annular surface;
- a second electrically conductive coil having a first annular surface and a second annular surface;
- a first spacer, the first spacer being electrically insulating and having a first face and a second face, the first face being separated from the first annular surface by a first gap;
- a gap-setting feature between the first spacer and the first electrically conductive coil, configured to set a width of the first dap,
- a fluid inlet;
- and
- a fluid outlet,
- wherein:
- a fluid path extends from the fluid inlet to the fluid outlet through the first gap, and
- the magnetic element is configured to cause fluid to flow through the first gap, in a direction having a radial component, between an inner volume of the first electrically conductive coil and an outer volume of the first electrically conductive coil.
