Zusammenfassung:2107464 9218822 PCTABS00017 A high temperature fluid-to-fluid heat exchanger (10) is described wherein heat is transferred from a higher temperature fluid flow core region (75) to a lower temperature fluid flow annulus (50). The wall (54) separating the high and low temperature fluid flow regions is comprised of a material having high thermal absorptivity, conductivity and emissivity to provide a high rate of heat transfer between the two regions. A porous ceramic foam material (60) occupies a substantial portion of the annular lower temperature fluid region (50), and is positioned to receive radiated heat from the wall (54). The porosity of the ceramic foam material (60) is sufficient to permit a predetermined relatively unrestricted flow rate of fluid through the lower temperature fluid flow region (50).
