Abstract

846,710. Making heat exchangers; jointing by tube-expanding. BABCOCK & WILCOX Ltd. Nov. 13, 1957 [Nov. 13, 1956], No. 34694/56. Classes 83 (2) and 83 (4). [Also in Croup XIII] A heat exchanger element is formed by expanding a tube into jointing engagement with a set of parallel fins inclined to the axis of the tube. A set of fin elements 8, each comprising a rectangular plate formed with three holes, are set up in a jig, comprising two spaced parallel combs arranged so that their teeth project towards one another, the fins 8 being arranged perpendicular to the axes of the centres of the holes. Three welded steel tubes 1 are then passed through the holes in the fins 8 and through holes in end plates 2, 3 held fixed. One comb is then moved longitudinally relatively to the other to incline the fins 8 and the tubes 1 are expanded by fluid pressure to form expanded joints between the tubes and the plates 2, 3 and fins 8. Other groups of tubes 1 and fins 8 are then assembled between the end plates 2, 3 and these tubes are expanded. Fifteen groups of three tubes and associated fins may be fitted. The projecting ends of the tubes 1 are welded to the outer surfaces of the end plates 2 and 3 and distributers 4 and collectors 6 bolted to the end plates. The holes in the fins 8 may be elliptical in which case a jig with fixed combs may be used and the fins 8 set up obliquely to the tubes. The holes could be circular and this method used. The holes may be punched in the fins 8 to produce a bevel, the tubes 1 being then passed through from the bevel side. The fins may be threaded on to the tubes before positioning in the jig. Any number of tubes or a single tube may be associated with each fin. The thickness of the fins may taper from the holes to the edges.
