Heat exchanger and method of cooling a flow of heated air

Abstract:

A heat exchanger is constructed from a plurality of plate pairs stacked to form air flow passages between adjacent ones of the plurality of plate pairs and cooling fluid flow paths within each of the plurality of plate pairs. The cooling fluid flow paths have a first portion along one longitudinal edge of each plate pair, a second portion along an opposing longitudinal edge each plate pair, a third portion extending through the heat exchange section between the first and second portions, and a fourth portion extending between the first and second portions along one lateral edge of each plate pair and bypassing the third portion. Flow barriers are arranged within each plate pair to at least partially define the third and fourth portions.
