Title:
LOCALIZED SOLAR COLLECTORS
Document Type and Number:
WIPO Patent Application WO/2017/200617
Kind Code:
A3
Abstract:
A localized heating structure (30) includes a spectrally-selective solar absorber (34), that absorbs incident solar radiation and reflects at wavelengths longer than 2/lm, with an underlying heat-spreading layer having a thermal conductivity equal to or greater than 50 W/(mK), a thermally insulating layer (32), adjacent to the spectrally-selective solar absorber (34), having a thermal conductivity of less than 0.1 W/(mK), one or more evaporation openings (38) through the spectrally-selective solar absorber (34) and the thermally insulating layer (32), and an evaporation wick (40), disposed in one or more of the evaporation openings (38) in the thermally insulating layer (32), that contacts liquid and allows the liquid to be transported from a location beneath the thermally insulating layer (32) through to the spectrally-selective solar absorber (34) in order to generate vapor from the liquid. The thermally insulating layer (32) is configured to have a density less than the liquid so that the localized heating structure is able to float on the liquid.
