Abstract
A cooling system including a cooling duct adjacent to the hot air duct of an air heater. The cooling duct includes a first wall and a second wall spaced from the first wall such that a passageway is formed therebetween. A wire mesh sheet is arranged in the duct passageway. The wire mesh sheet comprises a plurality of layers of wire mesh and has an undulate configuration which together with its density prevents substantial heat radiation from the first wall of the cooling duct to the second wall without significantly impeding airflow through the cooling duct. Cooling air introduced into the cooling duct flows through the duct, removes heat, radiated by the first wall and absorbed by the wire mesh sheet, and carries that heat away from the duct as it exits through the outlet opening. In this way, the system cools the first wall and prevents any significant heat transfer to the second wall of the cooling duct and elements in the vicinity thereof.
