ABSTRACT:
Disclosed is a method and apparatus for controlling coolant distribution in ohmic heating and other poloidal field magnetic coils. The apparatus consists of a coolant inlet and outlet arrangement with spiral coolant channels positioned therebetween. The spiral coolant channels are designed to control the coolant pressure drop within the coil turns and hence the coolant flow distribution within the entire coil. The coolant channels of the present invention provide coil turns with improved structural and cooling characteristics over the prior art. The method disclosed consists of controlling the flow distribution of cooling fluid through coolant channels in a magnetic coil by using spiral channels of a specially designed length, width and spiral configuration.
