ABSTRACT:
A heat exchange element, particularly suitable for use as a recuperator for external combustion engines, or a body for use as an afterburner or in filtration and osmosis, may be produced as a monolithic, ceramic, honeycombed body having a plurality of flow paths therethrough for two or three fluids wherein multiple flow paths of separate fluids are separated by walls which may be less than 10 mils thick.
In a preferred method, a honeycombed ceramic body is provided with a plurality of open-ended cells extending from one face end to another face end and arranged in vertical columns of cells separated by vertical fluid barrier wall surfaces. Selected columns of open-ended cells are closed on both face ends of the body and entrance to and exit from the selected cells is provided by removing portions of cell walls near face ends of the body between fluid barrier wall surfaces. A first fluid may enter the selected columns of cells through inlet openings on the top or bottom of the body and exit from the other end of the body through outlet openings. A second fluid may pass through unselected columns of cells. Three fluids may be accommodated by dividing the honeycombed body into independent upper and lower halves separated by an intermediate fluid barrier.
Fluids are applied to the heat exchanger and removed therefrom through appropriate use of sealable header or flue assemblies communicating with all entrance or exit openings.
