ABSTRACT:
A heat exchanger has a plurality of fluid flow tubes secured adjacent their ends by tube sheets. Cleaning elements are adapted to shuttle back and forth in the tubes and are adapted to be received by capturing cages. The inner ends of the cleaning element capturing cages are provided with enlarged collars having generally semi-circular flanges providing inclined undercut seats. The heat exchanger tube ends extend fully through the openings in the tube sheets and are provided with annular flared lips extending outwardly from the outer tube sheet faces. The cages are mounted directly to the tubes by bringing the collar seats down into hanging engagement with the tube lips.
