The single-circuit solar collector consists of an absorber which is arranged in a housing and is formed from a number of parallel tubes which can be flowed through vertically or at an angle in relation to the vertical, are arranged with a small spacing from one another, are interconnected on the inlet and outlet side and are circular in cross-section. …<??>The parallel tubes (1) are connected in a liquid-tight manner with their open ends (2) to two transverse tubes (4) provided with connection pieces (3), at their connection pieces (3). The transverse tubes (4) are provided with a greater diameter than the parallel tubes and in each case provided at at least one of their end closures (5) with in each case a heat-transfer medium connection piece (6). Each transverse tube (4) is formed from a sheet-metal blank which has the connection piece (3), is folded and/or rounded into a tube and is closed with a longitudinal seam. …<IMAGE>… |
