SOLAR HEAT LIGHT COLLECTION DEVICE AND SOLAR HEAT LIGHT COLLECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To restrict reduction of light collection efficiency caused by shades of pipes and supporting parts and restrict influence of strong wind against pipes.SOLUTION: Even if sub-pipes connected to receivers 8 and main pipes connected to the sub-pipes are sub-supply pipes 6 and main supply pipes 3 for supplying fluid to the receivers 8 or sub-discharging pipes 7 and main discharging pipes 4 for discharging fluid from the receivers 8, a plurality of sub-pipes are merged into the main pipes, thereby a diameter of the sub-pipe is made finer and lighter weight than that of the main pipes. With this arrangement as above, the supporting parts for supporting the sub-pipes are also made fine. Further, the main pipes are arranged at positions where incidence of solar light into mirrors 9 and the receivers 8 is not prevented. Under the above arrangement, a reduction of light collecting efficiency influenced by the shades of the main pipes, sub-pipes and the supporting parts is restricted, and influence of strong wind against the pipes due to light-weight formations of the sub-pipes is restricted.SELECTED DRAWING: Figure 1
