Abstract
A plurality of mutually parallel finned tubes forming a heat exchanger are positioned so closely together that the peripheries of mutually oppositely extending segments of the tube's respective fins are not substantially interspaced. To support the finned tubes, one or more groups of those segments are shortened to form transverse passages through which tube support members are passed transversely with respect to the tubes.
