Radial flow annular heat exchangers

摘要: A heat exchanger and method of transferring between fluids is disclosed using a plurality stacked plate pairs consisting face-to-face, mating, ringlike plates, each having an outer peripheral flange, annular inner boss located in common plane with the offset intermediate area flange boss. The flanges bosses mating plates are joined together. areas have outwardly disposed aligned inlet outlet openings forming manifolds for flow first exchange fluid circumferentially through from manifold to manifold. also has header enclosing either or cause all second pass transversely relative fluid. Flow augmentation means, such as ribs grooves, dimples turbulizers can be used inside pairs, if desired.
