A heat exchanger (1a, 1b, 1c, 1d) with highly flexible use, comprising a box-like body (2a, 2b, 2c, 2d) which delimits inside it at least one heat exchange chamber (3, 13, 23) and has at least one inlet (4) and at least one outlet (5) for the passage through the heat exchange chamber (3, 13, 23) of combustion products along a preferred path. More specifically, the box-like body (2a, 2b, 2c, 2d) defines at least partly in its side walls at least one duct for feeding a fluid to be heated and inside the heat exchange chamber (3, 13, 23) heat exchange elements (7) are provided and are associated with the supply duct in order to increase the thermal efficiency of the heat exchanger (1a, 1b, 1c, 1d). The peculiarity of the invention consists in that it comprises a plurality of distinct modular elements (8a, 8b, 8c, 8d, 9a, 9b, 9c, 9d) which are mutually interconnected in order to define the box-like body (2a, 2b, 2c, 2d). Advantageously, each modular element (8a, 8b, 8c, 8d, 9a, 9b, 9c, 9d) comprises at least one portion of the heat exchange elements (7), at least one portion of the supply duct and at least one portion of the heat exchange chamber (3, 13, 23) in order to obtain a heat exchanger (1) of differing dimensions and technical characteristics according to requirements. |
