Abstract (en)
[origin: WO2010008311A2] Low concentration CPC type concentrating collector, without optical losses and without thermal shorts which would be responsible for substantial efficiency losses, comprising at least one absorber (1) one absorber tube (10), concentrating reflectors (2) and at least one bottom set (3), said absorber (1), concentrating reflectors (2) and bottom set (3) being superimposed but without touching each other, and having a concentration value in the range of about 1 to 3. The absorber (1) has a surface selected from the group comprising an inverted V shape, any open polygonal line and/or curve and the like and combinations thereof. The invention further contemplates an absorbing grid formed by said concentrating collectors, which allows the overcoming of the thermal and optical positioning difficulties due to higher temperatures, since it comprises a system of expansion guides (13) allowing for its expansion in the longitudinal direction.
