Use of plate-shaped components as absorbers in solar collectors

摘要

The invention relates to the use of plate-shaped made of components made of open-celled foam materials, especially coloured black, based on a melamine resin condensation product as an absorber in solar collectors. Transparent cover plates are then arranged on the sun side of the components in front such that a heat exchange medium, especially air, can be conducted through the components and also through channels formed by the cover plates and the components.
