Abstract

The collecting elements of a solar energy trap are formed of two concentric tubes which can be positioned vertically, horizontally or obliquely. The space between the tubes is at a high vacuum. The outer tube is transparent and the inner tube may be opaque or transparent. An opaque tube material has good heat absorbing properties. With a transparent inner tube either the heat carrying fluid is coloured or contains particles, e.g. C black, in suspension or there is a solid element, e.g. rod or tube with good absorbent properties inside the inner tube. A reflective element which may be a thin metal sheet or reflecting layer is positioned between the two tubes on the side opposite the sun. The collecting elements, of which there are >=2, in the solar energy trap, are connected together in series or in parallel. Rigid or flexible connections are used. When connected in parallel the connecting headers are sepd. by calibrated bracing rods to ensure a suitable compression on the joints between the headers and the inner tubes. Used for heating domestic or industrial water, heating or air conditioning of a building or for conversion to electrical or mechanical energy. The weight is less and clost price per square metre reduced. Efficiency is less affected by ambient temp. wind and angle of incidence of sun's rays.
