Heat exchanger (10), in particular for condensing boilers (100), comprising two components assembled to each other: - a main body (11), and - a container (13). The heat exchanger (10) characterized in that the main body (11) is formed as a single piece, and presents a first plurality of channels (15) for the passage of exhaust gases according to a first direction (F1), and a second plurality of ducts (18) for the passage of water whose pathlines run according to second directions (F2). In addition, the second plurality of ducts (18) is arranged as a labyrinth, and in such a way that the second directions (F2) of water pathlines are substantially perpendicular to the first direction (F1) of the exhaust gas. |
