Abstract
A heat exchanger is disclosed which comprises an outer shell, a bundle of heat exchange tubes within the shell and positioned within a tube sheet adjacent one end thereof, and a shroud spaced between the shell and the tubes. The exchanger is constructed so that hot incoming fluid passes over the heat exchange tubes inside of the shroud and then, in its cooled state, passes along the back face of the tube sheet and between the outer surface of the shroud and the inner surface of the shell, so that thermal stresses in the tube sheet are minimized.
