Solar heat collecting panel - with biconvex lenses focused on heat conductive layer under plastics foil

摘要

Theouter layer of the panel is pref. made of flexible plastic foil, with a large number of bicovex glass or plastic lenses embedded in it. These focus the solar rays to a heat conductive layer which covers the conduit for the heat transfer medium. The heat conductive layer pref. has attached metal turfts which penetrate in the conduit to transfer the heat. This very easily transported system which can be applied over large areas such as hillsides.
