Solar energy collector for agricultural drier - has transparent plastics sheet with sealing layer forming circulation conduit for air

摘要

The captor has a sheet of plastics (3) permeable to solar radiation and a sealing layer (5), with the two joined to define a circulation conduit (6) for air, the conduit having ports of entry (9) and exit (10). The captor has a layer of textile material (4) that absorbs the solar energy, the layer being held adjacent to the sealing layer (5) and situated at the interior of the circulation conduit. Pegs or stakes (15) pierce holes in the edges of the sheet holding the collector (1) to the support surface (2), while the sealing layer can be made of a sheet of plastic material.
