Two-dimensional Fresnel solar energy concentration system

摘要

The present invention provides a solar energy concentrating reflection system comprising multiple arrays of solar reflectors arranged adjacent to one another on a generally planar support structure where each of the reflector arrays configured into a first Fresnel array in a first dimension. Each of the first Fresnel array of reflectors are in turn arrayed and supported in a support frame in a configuration of second Fresnel arrays in a second dimension such that solar energy from the sun is reflected and concentrated to a predetermined focal line. A solar receiver is disposed in the focal line of the configured solar reflectors such that the first and second Fresnel arrays uniformly reflect and concentrate solar energy from the sun onto the solar receiver within the first and second dimensions with a uniform solar intensity profile.

1. A solar energy concentrating reflection system comprising:
a plurality of rotatable support structures; multiple arrays of generally planar solar reflectors arranged adjacent to one another on a respective rotatable support structure from the plurality, each of the reflector arrays configured into a first Fresnel array in a first dimension; each first Fresnel array of reflectors in turn arrayed and supported in the plurality of rotatable support structures in a configuration of second Fresnel arrays in a second dimension such that the first and second Fresnel arrays are Fresnel arrayed relative to each other in both the first dimension and the second dimension within the support structures; a linear actuator and a cable, said cable connected to said linear actuator and wrapped completely around each of the rotatable support structures in turn, in a self-cinching configuration; a solar receiver disposed in the focal line of the configured solar reflectors; the first and second Fresnel arrays uniformly collecting and concentrating solar energy from the sun onto the solar receiver within the first and second dimensions with a uniform solar intensity profile; and, the rotatable support structures configured to rotate the first and second Fresnel arrays in the first dimension and in the second dimension, respectively, for tracking the sun.
