    Abstract: 1,107,455. Tubular heat exchangers. BADISCHE ANILIN- & SODA-FABRIK A.G. 25 June, 1965 [27 June, 1964], No. 26949/65. Heading F4S. A tube-and-shell type heat exchanger for enhancing flow without a high pressure drop of a heat exchanging gas over the polygonally distributed removable tube bundle 1 thereof comprises a pressure-resisting shell 6 spaced by an annular one-piece or multipart web 10, capable of compensating for differing axial changes of the bundle and shell, from a double-walled hollow jacket 7 surrounding almost the whole axial length of the tube bundle. An inlet 9 for the heat exchanging gas flowing over the bundle is sealed from direct communication with an outlet 11 therefor by the web 10, thus forcing the gas through the labyrinth between the tubes of the bundle, which is held conventionally by tube sheets 2, 3 mounted peripherally in stuffing-boxes 4, 5 on the shell 6, which also has an inlet 12 and an outlet 13 for the fluid flowing through the tubes of the bundle. The inlet and outlet 9, 11 may be varied in position along the shell, as disclosed in Figs. 2, 3 (not shown), the latter of which discloses a tube sheet 3 having a cylindrical axial extension 14 attached by a collar 15 held in a clamp 16 to the tube shell, while the tube sheet 2 is connected thereto by a corrugated tubular compensator 17 allowing for different axial expansions of the components. When the tube bundle is not removable from the shell, the web 10 may be in the form of a corrugated ring.
