Solar collector with glass pane arranged upwards which reduces heat radiation and is in direct contact with the absorber-heat transfer device combination

摘要

The collector has a liquid-cooled absorber heat exchanger combination (3) comprising an upward plane or an uneven surface and/or made from metal and plastic. A glass pane (1) is provided on an upper side with a low emitting coating (2) for thermal radiation. The glass pane is attached near at the absorber heat exchanger combination and in direct contact with the absorber heat exchanger combination. The absorber heat exchanger combination is in contact with the glass pane by lamination or sticking in a planar, strip or point form.
