Radiation collector
First Claim
Patent Images
1. A radiation collector comprising:
- a pressure cell at least partially formed from a first flexible membrane and comprising a transparent region;
a concentrator fixed within the pressure cell, the concentrator comprising a second flexible membrane comprising a first side facing the transparent region and a second side facing away from the transparent region;
wherein the concentrator is disposed between a first pressure chamber and a second pressure chamber formed within the pressure cell;
wherein the first pressure chamber and the second pressure chamber are fluidly coupled to an exterior environment; and
wherein, responsive to deformations caused by external influences of at least one of the first pressure chamber and the second pressure chamber, a predefined pressure range within the first pressure chamber and the second pressure chamber is maintained.

Abstract
Disclosed is a radiation collector comprising a pressure cell which is subdivided into a first pressure chamber and a second pressure chamber by means of the concentrator. The small pressure difference between the pressure chambers keeps the concentrator operational in a beam-concentrating form and reduces the wear on the reflective layer of the concentrator. The radiation collector further comprises adequately designed means for establishing the desired pressure in the respective pressure chamber, said means making it possible to compensate changes of the pressure chamber volume resulting from wind load, for example.
