Parabolic trough collector with segmented parabolic trough geometry

摘要

The invention relates to a parabolic trough collector (10) comprising a mirror surface (12) and an absorber tube (18), a focal line (16) of the mirror surface (12) running inside the absorber tube (18). The mirror surface (12) comprises at least two paraboloid mirror segments (13), and at least two mirror segments (13) have different focal lengths.
