Coated alternating-flow heat exchanges and method of making

摘要

An alternating-flow heat exchanger and method of forming is disclosed, in which a substrate is provided having open-ended, straight passageways therethrough, and at least one end cap for diverting flow in said passageways into primary and secondary flow paths. The ceramic substrate is coated with a desirable coating. The end cap is then applied to the substrate to direct flow from the passages in first and second flow paths.
