Abstract
A method of producing a tubular thermal structure in which cooling tubes are sandwiched between first and second members which are in turn sandwiched between first and second fixtures which fix the relative relationship of the members. The tubes, members and fixtures are then heated to a temperature at which plastic or superplastic deformation of the tubes will occur, and each tube is then subjected to a pressure differential sufficient to cause each tube to expand into intimate contact with adjacent tubes and the first and second members. The pressure is maintained until each of the tubes bonds to the adjacent tubes and the first and second members.
