Abstract

1,200,681. Heat exchange tubes. HUTOGEPGYAR. 3 April, 1968 [13 April, 1967], No. 16081/68. Addition to 1,012,898. Heading F4S. In the parent invention, fins such as 3a, 3b are wrapped around tapering projections 2 and are thereby secured to the tube 1. In the present improvement the projections 2 are supple mented by shoulders 4 enabling the fin to be clamped between the shoulders and the projection when pressure is applied in the direction 6. The applied pressure may merely squeeze the fin material into the gap between a projection 2 and an adjacent shoulder 4 (Figs. 2, 3a and 3b); or, as shown, the projection and/or the tube may be deformed, again by pressure applied in the direction 6, to narrow the gap and thereby grip the fin.
