<p>Solar thermal collector body in the form of an integrally extruded or continuously cast panel including as an integral part of its cross-sectional profile a tubular hollow body adapted for the flow therethrough of a flowable heat carrier medium, including ends which permit the inflow of cold heat carrier medium and the withdrawal of the heated heat carrier medium respectively. The hollow body (1) is used as part of a solar collector Solar thermal collector including a collector box having a bottom area and side walls (13) and optionally a cover (16) allowing the entry of solar radiation into the box and forming a barrier against the escape of thermal radiation from inside the box wherein in a space above the bottom surface one or more thermal collector bodies (1) adapted for the through flow of a flowable, solar heat absorbing heat carrier medium is accommodated and is connected or connectable to feed and withdrawal ducts respectively for the heat carrier medium.</p> |
