<p>A solar energy collector includes a heat exchanger (10) which extends over an external wall of a building and includes at least two throughflow passageways (121, 122) for heat transporting fluid, for instance air. The passageways (121-124) are delimited by sheets (12, 13, 14, 32, 33) which are mutually spaced in a direction perpendicular to the exposed surface of the heat exchanger, such that the throughflow passageways (121-124) are mutually separated in said perpendicular direction. The wall sheets defining said throughflow passageways (121-124) have an adapted transparency for selective distribution of incident radiation energy, such as thermal energy, to different passageways. Some (31-34) of the sheets defining said passageways are corrugated.</p> |
