Abstract
The fixed focus parabolic trough collector comprises a mirror structure (10) with a plurality of mirror segments (S1, S2, S3, . . . ). At least two adjacent mirror segments (S1, S2) form a gap (14) through which radiation (R3) reflected by a third mirror segment (S3) is incident on the absorber pipe (13) positioned at the focal point of all mirror segments. This minimizes the path of the reflected radiation. The mirror structure has compact dimensions relative to the aperture opening and is minimally affected by wind.
Claims8
A fixed focus parabolic trough collector comprising an elongated mirror structure forming a focal line, and comprising an absorber pipe extending along the focal line,
- wherein the mirror structure further comprises a plurality of mirror segments, whereby at least two adjacent mirror segments form a gap through which radiation reflected by a mirror segment is incident onto the absorber pipe.
