Patent ID: 7545062

Claim:
A device for removing heat from an electrically conducting coil of a magnetic device by convection, the device comprising: a ribbon-type conductor portion, having a width, for conducting heat from the magnetic device's electrically conducting coil, the ribbon-type conductor portion being structured and arranged spirally in a coil; an insulating portion, having a width greater than the width of the conductor portion, that is structured and arranged spirally and coaxially with the ribbon-type conductor portion so that a section of the insulating portion is interposed between adjacent segments of the conductor portion along the length of the coil, the insulating portion including: a plurality of window portions, each having an opening size that is greater than the width of the conductor portion, to provide a fluid flow passage along each exposed surface of adjacent segments of the conductor portion of the coil, and a plurality of strip sections that separate adjacent window portions from the plurality of window portions for providing a plurality of fluid flow passages between adjacent conductor segments of the conductor portion in the coil.
