<p>A 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), as well as a plurality of fins (4) arranged transversely with respect to the ducts (1) and provided with holes to be crossed by the latter, further includes a plurality of inserts (5) arranged to the inside with respect to the ducts (1) and connecting pairs of adjacent fins (4). The arrangement and shape of the inserts (5) allow to absorb in an optimal manner not only the energy directly transmitted by the solar rays hitting the fins (4), but also the energy, even if very low, reflected by these fins (4), and the protected position of the inserts (5) inside the exchanger case prevents or at least minimizes the dissipation of heat by convection caused by possible air streams touching the surface of the exchanger.</p> |
