PROFILE OF PIPING FOR A HEAT EXCHANGER, HEAT EXCHANGER FOR CONDENSATION BOILERS PROVIDING SAID PROFILE, AND CONDENSATION BOILER PROVIDING SAID HEAT EXCHANGER
The present invention relates to a profile (1) of piping, in particular piping for making a heat exchanger (10) for a condensation boiler (20), characterized in that the cross-section of the profile (1) has a trapezoidal portion (2), having two bases (4, 5) and two sides (6, 7), and a triangular portion (3), having a base (6) and two sides (8, 9), wherein a first side (6) of the trapezoidal portion (2) coincides with the base (6) of the triangular portion (3), wherein the second side (7) and the bases (4, 5) of the trapezoidal portion and the sides (8, 9) of the triangular portion (3) form the inner walls of the profile (1), wherein a first angle (a) between the first base (4) of the trapezoidal portion (2) and the first side (8) of the triangular portion (3) adjacent to it is comprised between 45° and 135°, preferably 90°, wherein a second angle (β) between the second base (5) of the trapezoidal portion (2) and the second side (9) of the triangular portion (3) adjacent to it is comprised between 180° an
