摘要: A receiver for converting concentrated solar radiation has a channel, an absorber structure arranged at the entrance of the channel and exposed to the concentrated solar radiation, made of an air-permeable fibrous mat. The receiver also has means for conveying air as coolant through the absorber structure. In order to ensure on the one hand that the material absorbs the solar radiation in the described manner and on the other hand that it is held in a reliable manner in the channel, the mat (7; 10, 11) has an increasing thickness in the air flow direction.
