In order to provide a trough-shaped collector for radiation, in particular for solar radiation, comprising a trough-shaped mirror extending in longitudinal direction and reflecting the radiation into a focus region, and an absorber line extending in longitudinal direction through the focus region of the trough-shaped mirror and having a guide tube for the heat transport medium and an absorber pipe surrounding the guide tube such that an annular chamber is formed between guide tube and absorber line, with which the problems existing as a result of the uneven irradiation of the absorber line are also reduced or eliminated, it is suggested that an annular passage medium flow in the annular chamber and that the annular passage medium couple the guide tube thermally to the absorber pipe.

[ What is claimed is:] [1.] A trough-shaped collector for radiation, comprising:a trough-shaped mirror extending in a longitudinal direction and reflecting the radiation into a focus region; andan absorber line extending in said longitudinal direction through the focus region of the trough-shaped mirror;said absorber line comprising:an absorber pipe having an absorber screen which absorbs the radiation reflected from said mirror;a guide tube adapted to carry a heat transport medium for transporting heat resulting from radiation absorbed by said absorber screen;said absorber pipe surrounding the guide tube such that an annular chamber is formed between said guide tube and said absorber pipe,said annular chamber being adapted to carry an annular passage medium in said longitudinal direction via a closed circuit to efficiently transfer the heat resulting due to said absorption from said absorber pipe to said guide tube and heat said guide tube essentially over its entire circumference.
