Abstract (en)
[origin: WO2004090434A1] A heat exchanger (4) for a gas boiler (1) for producing hot water has a casing (13) extending along a first axis (Al) and through which combustion fumes flow; a tube (14) housed inside the casing (13), extending along a second axis (A2), and coiled about the first axis (Al) to form a succession of turns (19) along which water flows; and a deflecting disk (15) for directing the fumes between successive turns (19) in a given direction (Dl) ; the tube (14) having a first and a second fin (25, 26) which are located on opposite sides of the tube (14), and are continuous and parallel to the second axis (A2) and to the aforementioned given direction (DI).
