PURPOSE:To contrive to simplify piping and facilitate heat-insulating work, by improving a method of piping for feeding water to and discharging water from a water pipe which is integral with a heat-collecting plate, in a device comprised of two or more solar heat collectors arranged in a row on left and right sides. CONSTITUTION:The heat-collecting device 1 comprises two solar heat collectors 2 arranged in a row on the left and right sides, each of which collectors 2 is so constituted that a plurality of heat-collecting plates 5 comprised of the water pipes 4 extended in the fore and aft direction are incorporated in a case 3. Both end of the water pipe 4 are connected to headers 6, 7 extended in a direction orthogonal to the pipe 4, and a water-feeding pipe 8 extended in parallel with the header 7 is connected to one end of the header 7 though a U-shaped pipe 13. The headers 6, 7 and the water-feeding pipes 8 of the adjacent heat collectors 2 are connected through pipes 10-12, respectively, the right end of the header 7 of the heat collector 2 on the right side is closed, and the right end of the water- feeding pipe 8 is connected to a water-supplying port. |
