ABSTRACT:
A dry expansion heat exchanger of the tube and shell type. The heat exchanger comprises a shell having a plurality of bundles of tubes therein and a pair of end bonnets on opposite ends of the shell. Secondary baffles within the bonnets subdivide the bonnets into subchambers that are aligned with respective bundles of tubes. The cross-sectional areas of successive bundles of tubes increase to allow for expansion of the coolant as it flows through the heat exchanger and absorbs heat from the fluid to be treated. The secondary baffles define restricted flow areas for the coolant which have increasingly larger cross-sectional areas for successive chambers in the end bonnets.
