Patent ID: 7250141

Claim:
A vehicle, comprising: at least one environmental control system for providing conditioned air to a cabin of said vehicle; and at least one compressed air source for providing an air stream to said at least one environmental control system, wherein said environmental control system comprises a catalytic heat exchanger system adapted for cooling said air stream and for catalytically removing at least one pollutant from said air stream, wherein said catalytic heat exchanger system comprises: a catalytic precooler disposed within a first housing and cooling said air stream, catalytically removing said at least one pollutant, and having an offset cross-flow plate-fin configuration, wherein said offset cross-flow plate-fin configuration increases turbulence of said air stream passing through said catalytic precooler; and an augmentative catalytic device disposed in series with said catalytic precooler and within said first housing, wherein said augmentative catalytic device catalytically removes said at least one pollutant, wherein said augmentative catalytic device includes a single plate-fin layer and has a spiral plate-fin configuration, and wherein each of said catalytic precooler and said augmentative catalytic device is independently capable of catalytic ozone conversion.
