Heat exchanger structure

Abstract

A plate is disclosed for use in a plate-fin heat exchanger, comprising a generally planar elongated member having a longitudinal rib disposed along the longitudinal length of the member. The plate further includes a first plurality of beads having a height greater than the height of the rib as well as a second plurality of beads having a height approximately equal to the height of the longitudinal rib. The beads are arranged generally in rows having a planar space of predetermined longitudinal length therebetween into which an adjoining row of beads is placed when a pair of identical plates are laminated together in a face-to-face relationship and forming a heat exchanger. A heat exchanger comprising a plurality of stacked plates generally as described above is also disclosed.
