Definitions
- the present invention is directed generally to a solar concentrator having a gap between a primary reflector and a solar receiver.
- the invention is directed to a solar concentrator having an optimized positioning of a receiver (collector) relative to a primary reflector and a nearby groove or cavity in the profile of the primary reflector.
- the etendue matching requirement is satisfied by making sure the optical paths lengths of the extreme edge rays, which are at the ends of the input and output, are the same. This is accomplished by mirror segments at both input and output which bisect the angles between the extreme edge rays. One extreme ray is reflected into the other, causing it to retrace the same optical path. In this way the equality of optical paths is enforced by making the paths identical.
- This methodology requires mirror segments contiguous with input and output and in particular touching the absorber. However, practical considerations dictated a gap between absorber and reflector. The outlook as a result of the Hubert Integral theorem was that interposing a gap would result in loss of optical throughput, loss of concentration or both.
- the FIGURE illustrates in a two dimensional cross section the positioning of a virtual receiver relative to an actual solar receiver.
- a solar concentrator with a gap constructed in accordance with the invention is shown generally in the FIGURE and is indicated generally at 10.
- the solar concentrator 10 is shown only as a two dimension cross-section, but is understood to be extended transversely to a three dimensional unit for actual use.
- the solar concentrator 10 includes a primary reflector 20, which in a most preferred embodiment, comprises a tailored surface contour to optimize light collection efficiency. For example, see USPN 5,586,013, which is incorporated by reference herein as directed to the tailored reflector for achieving a desired purpose.
- V-notch 30 Coupled to the primary reflector 20 is a V-notch 30 having a characteristic surface contour preferably tailored as described hereinbefore.
- V-notch 30 itself can also be tailored to optimize its efficiency in processing light to the benefit of the solar concentrator 10.
- the position of the light receiver 35 is established by forming a tangent line 40 defined by points 50 and 60 which occur as the discontinuity between surface curvatures of the primary reflector 20 and the V- notch 30.
- a plane is formed between two lines which are established by the surface contour discontinuities between the primary reflector 20 and the V-notch 30.
