Abstract
The invention relates to an absorber element for solar high-temperature heat generation, having a light focusing element, an outer tube composed of a translucent material and an absorber which is arranged in it. The absorber is surrounded by at least one reflector channel having an opening gap. The focal line of the light focusing unit runs on the centre axis of the outer tube and the absorber does not lie on the centre axis of the outer tube. The opening gap of the reflector channel, through which the solar rays fall on the absorber, lies on the centre axis of the outer tube, and hence on the focal line.
Claims13
An absorber element for solar high-temperature heat generation, having a light focusing element, an outer tube composed of a translucent material and an absorber which is arranged in the outer tube and to which the solar rays are passed by the light focusing element, wherein
- the absorber is surrounded by at least one reflector channel, whose surface has a low emission and absorption capability, and which reflects the heat radiation which originates from the absorber back to the absorber;
- the focal line of the light focusing element lies on the centre axis of the outer tube, and the absorber does not lie on the centre axis of the outer tube;
- an opening gap in the reflector channel runs on the centre axis of the outer tube and the solar rays fall on the absorber through this opening gap;
- and
- the absorber comprises an absorber tube, through which a heat carrier medium circulates, and absorber plates which are mounted on the absorber tube, with the absorber plates being curved such that they essentially completely absorb the solar rays which are incident on them through the opening gap.
