RETAINER FOR HEAT EXCHANGER CLEANING ELEMENTS ABSTRACT OF THE DISCLOSURE A heat exchanger has a plurality of fluid flow tubes through which shuttle type cleaning elements are carried by the fluid, the direction of which is reversable. The cleaning elements are captured adjacent the tube ends by a transverse plate having cleaning element receiving openings therein. The plate is adapted to be mounted so that the openings register with the tube ends, and the plate openings are of sufficient length to contain the cleaning elements. At least some of the plate openings are connected by fluid flow slots which also communicate with the end chamber of the heat exchanger. A cleaning element stop device is disposed at the outer ends of the plate openings so that the cleaning elements are retained therein.
