Solar collector for utilizing solar energy for preparing hot water, particularly flat plate collector, has a tub-shaped housing which is locked by protecting glass, absorber, extending in distance under protecting glass

摘要

The solar collector (17) has a tub-shaped housing which is locked by a protecting glass, an absorber (10), extending in distance under the protecting glass. A lower absorber surface, the surface of the register pipe (11) and/or the inner surfaces of the housing (2) are laid to the side, is turned away to side of incidence of the solar radiation of the absorber and/or thermal coating (18) covers the foil-shaped insulators, reflecting and stopping heat energy. The absorber lower surface and the inner surfaces of the housing are provided with the thermal coating.
