PURPOSE:To reduce the loss of water head, by providing two header pipes in each of a plurality of modules, closing opposite ends of the two header pipes, and connecting the plurality of modules in series to each other. CONSTITUTION:In each of a plurality of modules 5, there are provided two header pipes 7, 8 arranged in parallel with each other and a plurality of solar- heat collector pipes 3 also arranged in parallel with each other and connected between the two header pipes 7 and 8. The two header pipes 7, 8 of each module 5 are closed at their opposite ends. Further, a plurality of modules 5, arranged in side-by-side relationship with each other in the manner that the end portions of the header pipes 7, 8 face toward each other, are connected in series to each other by use of pipe joints. With such an arrangement, it is enabled to simplify the piping work required at the time of installation of the apparatus and to reduce the loss of water head per unit module 5. |
