Abstract (en)
An electromagnetic induction coil (38) for a magnetofluidynamic device (36) includes a cable (22) enclosed within an insulator sheath (18) and composed of multiple individually-insulated conductor strands (24) wound in Litz-wire fashion in a relatively loose relationship to one another to form a semi-compacted bundle. The strands in the semi-compacted bundle define a plurality of empty spaces (26) between individual strands (24) for permitting coolant flow within the sheath (18) and through the bundle along and about the individual strands (24) such that amount of surface area of the strands (24) exposed to contact by the coolant is greater than in a compacted bundle of strands thereby enhancing the heat transfer capability of the cable (22).
