Absorber for solar radiation has sharp triangular battens on thick highly-conductive material with dark coating on side facing solar radiation

摘要

The absorber has sharp triangular battens (2) on a thick highly-conductive material (4) which is coated in a dark color, preferably black, on the side facing the solar radiation (1). The battens are at a set spacing from each other and are themselves made of a poorly-conducting material with a highly reflective outer surface (3).
