ABSTRACT:
The problem of providing a lightweight, efficient and compact impingement plate type heat exchanger for exchanging heat between at least two fluids is solved by providing a stack of generally parallel plates (36) which include end plates (38, 48), intermediate impingement orifice plates (98, 99) and intermediate manifold plates (96). Inlets (40, 54) and outlets (50, 42) for the two fluids are provided in the end plates. The impingement orifice plates have orifice areas (110) defining two tortious flow paths (68, 86) generally parallel to each other and generally perpendicularly through the plates for the two fluids. The manifold plates and portions of the impingement orifice plates have slots (102, 106) and openings (112, 114, 118) for distributing the two fluids parallel and perpendicularly through the stack of plates to their respective tortious flow paths. Therefore, all extraneous headers, manifolds and housing components are completely obviated.
