摘要:
A cushion-shaped concentrator for concentrating solar radiation in an absorber includes a transparent membrane that faces the incoming radiation and includes a reflector membrane which reflects the incident radiation in the direction of the absorber. The transparent membrane and the reflector membrane form an outer casing for a chamber filled with a gas at overpressure. Tension elements are arranged between the transparent membrane and the reflector membrane The tension elements produce constrictions on the reflector membrane that separate a plurality of distinct concavely curved sections of the reflector membrane.
摘要:
The invention relates to a cushion-shaped concentrator (1) for concentrating electromagnetic radiation, in particular solar radiation (S), in an absorber (2), comprising a transparent membrane (3) that faces the incoming radiation during operation and a reflector membrane (4) which reflects the incident radiation in the direction of the absorber (2). In order to create a simply designed, low-cost cushion-shaped concentrator (1), by means of which the electromagnetic radiation can be concentrated at high efficiency in an absorber (2), the transparent membrane (3) and the reflector membrane (4) form an outer casing (5) for a chamber (6) filled with a gas at overpressure, wherein tension elements (7) are arranged between the transparent membrane (3) and the reflector membrane (4), said tension elements (7) producing constrictions (E) on the reflector membrane (4) that separate concavely curved sections (A) of the reflector membrane (4).
