Abstract
The heat exchange assembly for unit heaters and like apparatus for the treatment of hot air is of the type comprising a heat exchanger formed of flues and air tubes and a combustion chamber. The inventive caracteristics thereof are the following: the flues (17) have, in cross-section, the shape of a trapezoid with the small base placed at the bottom; the air tubes (15) are arranged side by side in such a manner as to form therebetween a flue (17); the lower portion (19) of the air tubes forms the roof of the combustion chamber (9); the flues (17) have in cross-section the shape of a trapezoid with the small base placed at the top; the side walls (21) of the air tubes (15) are provided with impressions (18) for avoiding a laminar flow of the flue gas and imparting thereto the necessary turbulence. <IMAGE>
