Variable angle solar collector - has absorber with rectangular plate extending diametrally between reflector segment and glass

摘要

The solar energy collector has a housing formed by a concave reflector in the form of a segment of a cylinder, a flat/glass bearing on the two end generatrices of the segment, and a pair of flanges at the end of the reflector. In the housing is an absorber in a heat-transfer medium circuit between inlet and outlet pipes, aligned on an axis parallel to the cylinder generatrices. By rotation about this axis the glass is kept face to the sun. The absorber has a rectangular plate (11) extending in a diametral plane of the cylinder segment between the latter (7) and the glass (6). This plate is in close thermal contact with the medium over a substantial part of its surface.
