Abstract

A bladed solar thermal receiver for absorbing concentrated sunlight is disclosed. The receiver includes a plurality of panels arranged in a bladed configuration for absorbing sunlight. The bladed configurations can be radial or planar. The receiver design increases the effective solar absorptance and efficiency by providing a light trap for the incident solar radiation while reducing heat losses from radiation and convection.

First claim

What is claimed is:

1 . A solar receiver, comprising:
a flat, support panel having a vertical and a horizontal axis; and a plurality of solar receiver panels attached to and extending from the flat, support panel; wherein at least one solar receiver panel of the plurality of solar receiver panels comprises:
a first fluid header;
a second fluid header; and
a plurality of tubes fluidly connecting the first and second fluid headers.

2 . The solar receiver of claim 1 , wherein the plurality of solar receiver panels is vertically attached to the flat, support panel.

3 . The solar receiver of claim 1 , wherein the plurality of solar receiver panels is horizontally attached to the flat, support panel.

4 . The solar receiver of claim 1 , wherein at least one solar receiver panel of the plurality of solar receiver panels is pivotally attached to the flat, support panel.

5 . The solar receiver of claim 1 , wherein at least one of the plurality of solar receiver panels extend horizontally or perpendicular from or to the vertical axis.

6 . The solar receiver of claim 1 , wherein at least one of the plurality of solar receiver panels extends vertically or parallel from or to the vertical axis.

7 . The solar receiver of claim 5 , wherein the at least of the one or more of the plurality of solar receiver panels can pivot with respect to the horizontal axis.

8 . The solar receiver of claim 6 , wherein the at least one of the one or more of the plurality of solar receiver panels can pivot vertically with respect to the vertical axis.

9 . The solar receiver of claim 1 , wherein at least one of the plurality of solar panel receivers comprises two or more solar receiver sub-panels.

10 . The solar receiver of claim 9 , wherein the solar receiver sub-panels comprise:
a first sub-panel fluid header; a second sub-panel fluid header; and a plurality of sub-panel tubes fluidly connecting the first and second sub-panel fluid headers.
