Abstract
An indirect heat exchanger having interconnected tubes arranged to form a plurality of generally-parallel, elongated tube sections spaced from one another in a predetermined pitch pattern to form geometric void spaces between adjacent combinations of the tube sections in planes generally-perpendicular to the tube sections and separate baffle plates arranged in each of a plurality of spaced planes generally-perpendicular to the tube sections so that there is a void space on all sides of the baffle plates in each plane and arranged in different planes so that there is a void space in the planes in front of and behind each baffle. In a preferred configuration the tubes are arranged in concentric circles and the planes are spaced at a plurality of angular positions.
