ABSTRACT:
An absorber body with flow paths for water or a flowable heat carrier for the direct or indirect heating of fluid or fluids or the like flow agents by solar energy in which the flow paths are produced by the deformation of plastic material, is improved in respect of its production and use in that a panel (12) is provided with slot-like openings, the width of which approximately corresponds to the width of the flow path, and welded on the panel is a foil (14) which is deformed through the openings to form respective shaped foil portions (15) of approximately channel-like cross-section as partial delimitation of the flow path and is sealingly covered on the side remote from the channel-like cross-section. In that arrangement, a carrier plate, a cover foil (50) or an insulating body (54) may be provided on the side of the panel (12) which is remote from the channel-like cross-section of the foil portion (15). The panel is provided with openings correspond to the pattern of the flow paths and is covered over its surface with the foil (14), whereupon the foil is deep-drawn through the openings.
