Transparent solar heat conserving double panel - with cross-arms between cover layers forming interconnected chambers through which fluid circulates

摘要

The panel is made of transparent material, esp. acrylic glass, with a series of parallel cross arm stems fixed between two cover layers to form adjacent chambers. The chambers (3) are interconnected, esp. in the area of the two end faces of the panel (1) where the cross arm stems (2) terminate, and a fluid flows through them. Another similar panel may be fastened on the flat side of the first panel facing the sum, or there may be a further covering layer on this side.
