Abstract
A primary fluid is circulated within vertical flexible tubes enclosed within a fluid-tight shell and a secondary fluid flows over the external tube walls. A secondary fluid admission chamber is formed in the top portion of the shell by a horizontal tube plate traversed by primary fluid distribution means. The upper end of each tube is fixed on a unit of revolution having a passage for the primary fluid and constituted by a sliding ring and two components. The first component has a frusto-conical external surface which cooperates with the internal wall of the ring. The second component has a cylindrical external surface provided with grooves which define passages for the downflow of secondary fluid with the internal wall of a tube-plate hole.
