Flat solar collector - has metal tub with several bridges formed by parallel arranged channels, and sealed by glass pane

摘要

The collector includes an absorber fluid for the absorption of a global radiation. The collector consists of a metal tub (1) with several bridges (2) formed by parallel arranged channels (8). The metal tub is sealed by a glass pane (3) with a high transmission for the global radiation of the sun densely. An inlet opening and an outlet opening (5; 1) are provided, where the cross-section of the inlet opening (5) for the absorber fluid (6) stands in a relationship of 1 to 12 or 13 w.r.t. the cross-section of the channels. The metal tub and the glass pane are densely and durably pasted with each other. The absorber fluid is simultaneously a heat carrier fluid.
