Abstract (en)

[origin: WO9964795A2] A solar collector unit (10) which includes a trough-shaped compound parabolic concentrator (12). The concentrator is formed of two integral side-by-side portions (14), each having a compound parabolic cross-sectional configuration which extends inwardly from a free edge (16) and terminates at a common apex (18), thereby defining a ridge portion extending along the length of the trough-shaped concentrator. The concentrator has a generally omega-shaped cross-sectional configuration. The concentrator also defines a focal region (14', 14'') parallel to the ridge portion. The solar collector unit also includes an elongate receiver construction (22, 24) extending along the length of the concentrator in the focal region, thereby to receive solar energy focused thereat by the concentrator. The elongate receiver construction has an arrangement of parallel, interconnecting conduits for carrying a throughflow of a fluid to be heated. The ridge portion of the concentrator intersects with a tangential plane (28) common to at least a pair of the conduits, thereby substantially preventing gap loss thereat.
