Solar heat exchanger panel - has thermally-insulated frame and rear wall, and absorbent support for black-coated, small bore copper conduit with continuous sections

摘要

Solar heat exchanger panel having a thermally insulating side frame and rear wall and a front glass pane is provided with a heat exchanger formed by a small bore copper conduit, which is coated with a black layer and whose sections are laid closely to one another, opt. with small gaps, to provide a conduit of great length. Heat transfer is optimised.
