RADIAL FLOW ANNULAR HEAT EXCHANGERS

摘要

A heat exchanger for transferring heat between fluids is disclosed. The heat exchanger comprises a plurality of stacked plate pairs consisting of face-to-face, mating, ringlike plates, each plate having an outer peripheral flange, an annular inner boss located in a common plane with the peripheral flange, and an offset intermediate area located between the peripheral flange and the inner boss. The peripheral flanges and inner bosses in the mating plates are joined together. The intermediate areas have outwardly disposed joined intermediate bosses having aligned inlet and outlet openings forming manifolds for the flow of a first fluid circumferentially through the plate pairs from the inlet manifold to the outlet manifold. The heat exchanger also has a header enclosing either they inner bosses or the outer peripheral flanges to cause all of a second fluid to pass between the plate pairs transversely relative to the flow of the first fluid.
