Packaging for heat exchangers

摘要

Packaging systems for gas to gas counter-flow heat exchangers include locating individual heat exchanger modules adjacent to each other within a housing and providing a plurality of plenum chambers partially defined by suitably arranged baffles. The arrangements disclosed provide heat exchanger assemblies wherein the length of fluid flow path is significantly larger than at least one of the width dimensions of the flow stream thus minimizing entrance effects which tend to reduce the efficiency of the system.
