Abstract

The invention relates to an absorber tube, especially for sun collectors (10) in solar thermal power plants, comprising a metal tube (22) for supplying and heating a heat transfer medium, and a sheath tube (24) surrounding the metal tube (22), for forming an annular space (26). The metal tube (22) has a first region (42) with a first diameter (d1) and at least another region (48) with another diameter (dw).
