Abstract
The heat exchanger () comprises a helical flow conduit () for a liquid, made with a pipe () of extruded thermally conductive material, provided with a pair of facing and mutually parallel fins (), which extend from a portion of the outer surface thereof. This pipe () is helically wound about a longitudinal axis (A-A) such as to form a sequence of adjacent turns () separated by interspaces () through which, during use, hot gases, in particular combustion fumes, flow. The fins () extend helically, towards the outside relative to the axis (A-A) of the helical conduit (), and have respective pluralities of through-openings () which interconnect the region () comprised between them and the interspaces () defined with respect to the adjacent turns (). Flow paths are thus defined through these fins (), outside the helical conduit (), for the hot gases which during use pass through the interspaces () between the turns of the helical conduit ().
