Heat exchanger comprising one or more ducts (1) suitable for being exposed to a source of solar rays (2) and for containing a fluid to be heated with the energy transmitted by these rays (2), wherein a plurality of fins (4) are arranged transversely with respect to the ducts (1), wherein at least one of the edges (4a, 4b) turned toward the solar rays (2) of two adjacent fins (4) is inclined so that these edges (4a, 4b) converge with an angle (a) less than 90°, and so on for the other fins (4), so as to form a series of pairs of fins (4) with the edges (4a, 4b) converging two by two. |
