Abstract

989,567. Heat exchanger tubes. CLAYTON DEWANDRE CO. Ltd. April 6, 1964 [Jan. 18, 1963], No. 2279/63. Heading F4S. A heat exchanger tube has an extended secondary heat exchange surface made from a metallic ribbon folded longitudinally to substantially U or L cross-section and wound on the tube to form an upstanding fin or fins. The ribbon shown has substantially rectangular slots b so that the completed fin consists of spaced fingers e connected by a continuous outer edge portion. The winding may be held to the tube by any known means e.g. a tension wire passing along over the base portions c, or by welding, brazing &c. with or without a tension wire. With small diameter tubes, the base portions c may be overlapped as in Fig. 5 (not shown) or the fingers e may be made narrower at the centre of the strip so that the base portions c will pack round the tube without overlapping.
