Device for concentrating solar radiation

The invention relates to the concentration of solar radiation onto an absorber in such a way that the concentrated energy flux density incident on the absorber surface is constant over this surface. In order to achieve this, the shape of the reflector is formed from a plurality of juxtaposed, internally mirrored hollow conical frustums; the absorber is provided with a conicity precisely matched to the shape of the reflector. The constant solar energy flux, which is concentrated over the surface of the absorber, ensures unambiguous thermodynamic conditions, avoids instability and enables an installation to be optimally configured. Particularly significant is the constant distribution of the concentrated solar energy flux for photovoltaic use, e.g. coating the absorber surface with solar cells. The main possible application is to the efficient generation of heat in the low-temperature range, and process steam generation for sea water desalination.

System for collecting radiant energy with a non-imaging solar concentrator

Implementations of a system for collecting radiant energy with a non-imaging solar concentrator are provided. In some implementations, the system may be configured to focus radiant energy striking a plurality of concentric, conical ring-like reflective elements of the non-imaging concentrator onto a receiver positioned thereunder and to rotate and/ or pivot the receiver so that at least a portion thereof is always kept within the focal point (or area) of the non-imaging concentrator. In this way, the non-imaging concentrator is able to focus radiant energy from the sun onto the receiver. In some implementations, the system for collecting radiant energy with a non-imaging solar concentrator may comprise a tracking apparatus configured to support the non-imaging concentrator and position it so that the sun is normal thereto, and a piping system that is configured to transfer concentrated solar energy from the receiver to an absorbing system where the energy is finally utilized.
