ABSTRACT:
The present invention relates to a heat exchanger and condensation combustion chamber assembly, comprising a plurality of tubes and including a front plate and a rear plate connected to the combustion chamber with a drop pattern.Each of the heat exchanger tubes comprises a variable area cross section, with a flat portion at a middle region, to provide a larger thermal exchange surface.The middle region is subjected to a crossed cut molding process to provide a helical type of fume path, suitable to enhance the efficiency of the assembly, owing to an increased thermal exchange between the fumes and heated air flows.The combustion chamber having a cross section of drop shape allows to properly solve the problem related to the very high temperatures generated by recent cylindrical gas burners having a metal mesh surface generating great amounts of heat, which must be disposed of in a thermal exchange process with the heated air flow.
