PCT No. PCT/SE83/00134 Sec. 371 Date Nov. 3, 1983 Sec. 102(e) Date Nov. 3, 1983 PCT Filed Apr. 13, 1983 PCT Pub. No. WO83/03660 PCT Pub. Date Oct. 27, 1983.A solar-energy collector having an absorber unit comprising two plates (1, 2) of rigid material, having an intermediate space for a flowing medium to be heated. In order to obtain a form-stable unit having temperature equilizing properties, the two plates (1, 2) are wave-shaped (3, 4) in mutually intersecting directions, symmetrically in relation to the main direction of flow of the medium, and the plates abut each other at the points of intersection, at which points the plates are joined together by welding, adhesive bonding or the like. |
