<p>A heat-exchanger (1) consists of a series of closely-spaced, essentially planar, pressure elements (11). Each pressure-element comprises a laminated plate-pair having surfaces formed to provide a plurality of ribbon like cavities between the plates, through which a working fluid can flow. Each plate-pair is joined around the common perimeter to produce a pressure-tight envelope having fluid-inlet and outlet ports at suitable locations. Between adjoining pressure-elements, heat-conductor plates (20) of corrugated profile are located; providing a series of narrow, approximately triangular- sectioned channels, distributed across each pressure-element, through which hot exhaust-gases can form a counter-flow with that of the pressure-element working fluid. The heat-conductor plates are engineered to react pressure-loading from the pressure-elements. The complete assembly of pressure-elements and heat-conducting plates is contained, in the direction of the major axis of the enclosure (23), between end-plates (25) retained by the body of the enclosure; by tie-rods, bars, or similar means.</p> |
