Solar energy collector, has convergent lens defining one of walls of casing, and mobile receptor held inside beams or in position intersecting beams by motor unit that controls movement of receptor with movement of beams

摘要

The collector has a convergent lens (2) e.g. planoconvex Fresnel lens, defining one of walls of a casing (1), where lateral walls (4a, 4c) and a bottom wall (3) of the casing are reflective. The depth between front walls and the bottom wall is lower than a focal distance (f) of the lens such that solar radiation beams (R1, R2) are concentrated on a final image focus (I'') located inside the casing. A mobile receptor (6a) e.g. heat pipe, is held inside the beams or in a position intersecting the beams by a motor unit that controls the movement of the receptor with the movement of the beams.
