A trough collector (1) for solar power plants comprises a pressure cell (25) containing an absorber pipe (42) for a heat-carrying fluid and also a secondary concentrator which is likewise arranged in the pressure cell (25). The pressure cell (25) thus can be reduced in height, which eliminates the need for reinforcements in the form of a framework structure for the pressure cell (25), which are otherwise required. |
