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.
Claims3
A heat exchanger comprising at least two tubes each encircled by a substantially continuous series of radially extending interspaced fins attached to the tube, the series extending longitudinally along the tube, said tubes being positioned closely together so that the peripheries of oppositely extending segments of their respective fins are not substantially interspaced, at least one of said segments of one of said fins being radially at least shortened to form a transverse passage between the tubes and through which a tube support member may be transversely passed, said one of said fins having at least one unshortened segment.
