ABSTRACT:
A heat-exchanger shell comprises a tube of generally cylindrical shape subdivided by a planar diametral partition plate into a pair of compartments. At each axially extending outer edge of the partition plate there is provided a one-piece seal unitarily formed of a pair of generally parallel inner flanges defining a groove in which the respective outer edge of the plate is snugly received and a pair of oppositely outwardly directed flanges bearing tightly radially outwardly on the inner wall of the tube. The seal may be made of a profiled piece of elastomeric synthetic-resin material, or of a piece of austenitic sheet steel. The shell is assembled by deflecting the inner flanges elastically apart and fitting them over the outer edges of the plate, then sliding the plate with the seals into the tube with simultaneous inward deflection of the outer flanges of the seals.
