Abstract
A rectangular frame contains a plurality of upwardly opening trays each having a heat absorber element with a plurality of upstanding vanes. A lens associated with each tray concentrates incident solar radiation on the vanes to preferentially heat a portion of the liquid filling the tray to a relatively high temperature at which vaporization is more efficiently accomplished than in prior solar stills. The evaporated liquid is condensed on an overlying surface and is collected for later use. The system may be used in distilling water and in solar refrigeration.
Claims7
A solar collector system, comprising:
- a frame;
- a tray supported by the frame and opening in an upward direction for holding a quantity of a liquid therein;
- an elongate heat absorber element mounted in the tray including upwardly extending parallel vanes which are spaced sufficiently close to one another so that liquid from the tray will be drawn up the vanes;
- and
- lens means mounted to the frame for concentrating incident solar radiation on at least a portion of the vanes for evaporating the liquid in the tray.
