A multi-plate dual flow path heat exchanger includes a plurality of stacked plates (70) each having a central section (71) provided with a number of longitudinal channels (72) separated by upstanding zig-zag walls (75), the channels (72) being provided on their floors (72A) with ridges (74), the floors and the ridges being of undulating form along the flow paths. Shallow ribs (75) extend laterally across the flow paths and in combination with the undulations assist in disruption of boundary layer flow. <IMAGE> |
