UN DISPOSITIVO RECEPTOR DE ABSORCION DE ENERGIA SOLAR, CON TRASPORTADORES SOLIDOS DE ENERGIA TERMICA

摘要

A solar receiver includes a panel having a plurality of absorbers, each composed of a multisided block (50) which includes an insert received in a bore (51) extending through the block. Opposing faces of the bore (51) and insert are fluted with a plurality of grooves (52, 61) which extend either in spiral paths of different pitches or in rotationally opposite curvilinear paths to define flow channels through the absorber. Radiant energy is absorbed through the absorbers and transferred to solid particulates which pass through the flow channels.
