ABSTRACT:
A heat exchanger has a plurality of fluid flow tubes secured adjacent their ends by tube sheets. Cleaning elements, such as brushes, are adapted to shuttle back and forth in the tubes. Cleaning element capturing cages or baskets are mounted to the tube ends. When the tube ends are of varying diameters along the plane of a tube sheet, some baskets are press fit into the larger diameter tube ends and an adhesive used to rigidly secure the members together, as heretofore. In addition, other baskets are loosely slipped over the smaller diameter tube ends. However, an adhesive is not necessary to rigidly fix these latter baskets in place. Instead, a connector device joins baskets which are not rigidly fixed against axial movement to those that are, so that the latter support the former in rigid interconnecting relationship. If the tube ends are all of the same diameter, only some of the baskets need be rigidly secured to the tube ends by an adhesive, with the other baskets interconnected thereto by connectors as described above.
