Concentrator for focusing solar radiation

摘要

A concentrator for focusing solar radiation onto an elongate absorber, comprising a plurality of transverse supports arranged one behind the other in the longitudinal direction, stabilizing the concentrator in the transverse direction and defining the shape of the concentrator profile, and a thin-walled support structure resting on said transverse supports and having a plurality of adjacent longitudinally extending ribs stabilizing the concentrator in the longitudinal direction. In the transverse direction, the support structure adapts to the curved profile of the transverse supports and forms a light-weight and strong bearing for a reflector plate.
