ABSTRACT:
A tube and shell type heat exchanger providing multi-pass contraflow of two heat exchange fluids includes a cylindrical outer shell, a modular baffle assembly guiding a shell fluid, a plurality of multi-wall tube sets and a pair of opposed end assemblies. A fixed end assembly fixedly receives one end of the tube sets and provides manifolding for directing multi-pass tube fluid flow through the tube sets. An opposite, floating end assembly slidably receives and seals floating tube ends to accommodate temperature induced expansion and contraction. The floating end assembly also provides manifolding for directing the multi-pass tube fluid flow through the tube sets. A triple wall tube set may be employed to provide extra protection against contamination of heat exchange fluids.
