Heat exchangers constructed of a plurality of composite ribbed sheets plates disposed and in a substantial parallel plate stacked relationship are disclosed. The sheets or plates can be spaced from each other by composite ribs or bars formed integral with or bonded to and between adjacent plates. The composite plates function as the fins of a conventional plate fin heat exchanger while the ribs form the passageways to separate adjacent fluids. The fins are specially constructed to maximize heat transfer between adjacent passageways formed by the ribs and the fluids flowing in these passageways.
