Abstract

The collector has a series of longitudinal troughs (3) which have a semi-circular cross section. They are placed side by side with their axes facing the sun and their open diametral sides are closed with sheets of glass or transparent plastic. Their internal surfaces are highly reflective. There is an absorber (2) within the hollow space of each reflecting trough. It has a central tube with projecting fins (14) which are blackened to absorb radiation. The tubes of all absorbers are connected to common flow and return pipes. The absorbers can be moved within the reflecting troughs to follow the path of the sun and receive direct radiation at all times. There is flexibility in the headers to follow this movement.
