Trough collector, for a solar power station, has a concentrator with a flexible membrane and a secondary concentrator

摘要

The trough collector (1) for a solar power station has a flexible membrane concentrator (60) in a pressure cell. Under working pressures, it concentrates the sun's rays (30,31) at a focal line outside the pressure cell. An absorber channel (64) within the pressure cell absorbs the concentrated sun's rays. A secondary concentrator (65) within the pressure cell is in the path (30',31') of the concentrating rays, to be deflected to a secondary focal line at the absorber channel.
