A multipass heat exchanger comprising an arrangement of a plurality of heat exchanger modules, each module having a plurality of passes for passage of a first heat exchange fluid and a plurality of tubes across such passes for passage of a second heat exchange fluid. The heat exchanger modules are disposed in side-by-side relation, with each successive module adjoining the previous module in a stepped relation, the second exchanger module being positioned relative to the first module so that the first heat exchanger fluid leaving the first pass of the first heat exchanger module enters directly the second pass of the second module, and so on, in a straight through fashion, for as many passes as desired. The result is a highly efficient multipass heat exchanger of minimum weight and pressure loss in the flow path on the shell side of the exchanger, comprised of multiple heat exchanger units, with no reversal of flow in each pass in each exchanger unit.
