ABSTRACT:
A catalytic air cleaner purifies air in enclosed spaces, such as in an aircraft or spacecraft. The air cleaner includes a pair of metal strips, wound into a double spiral. The strips have projections, affixed to the strips, to maintain the spacing between turns of the spiral. The spiral defines a core which accommodates an electrically heated catalytic converter. The strips themselves have no catalyst coating. A pair of ports at the periphery of the spiral allows air to enter and leave the spiral through inlet and outlet channels. Air entering the spiral through the inlet channel receives heat, by heat exchange, from air leaving the spiral, and then enters the core, where the electrically heated catalytic converter burns off various impurities. The air then leaves the spiral through the outlet channel, and becomes cooled by transferring its heat to the incoming air.
