INFLATABLE CONCENTRATOR FOR CONCENTRATING RADIATION AND METHOD FOR PRODUCING SAME

摘要

The invention relates to an inflatable concentrator (1) for concentrating radiation, in particular solar radiation, in an absorber that can be fastened thereto, comprising a sleeve (2), which is substantially tubular in an inflated operating state and which has a transparent inlet window (3) for coupling the radiation in, and a reflector film (4), which divides the sleeve (2) into at least two hollow chambers (5) and which has a mirror surface (4') that reflects the coupled-in radiation in the direction of the absorber, wherein the sleeve (2) is made of individual film elements connected to each other by means of joining connections (11; 11', 17), wherein the sleeve (2) can be arranged in a rolled-up transport position when not inflated, wherein at least one joining connection (11') is provided that extends substantially across the entire length of the sleeve (2) and that defines a longitudinal edge of the sleeve (2) when the sleeve (2) is not inflated.
