Inflatable solar collector
Patent
·
OSTI ID:6897519
A solar collector comprises an upper transparent flexible cover and a lower reflectively metallized sheet, the upper cover and the lower sheet both being flexible and the space between them being inflated under gas pressure. The joint between the upper and lower members is closed by longitudinal stringers that are carried by upright side walls that protect the lower sheet against deformation by the force of the wind. Tubes carrying the liquid to be heated are disposed within the inflated enclosure, the sun's rays being concentrated on them by the reflective coating on the lower sheet; and these tubes are appropriately moved so as to follow the focal point of the lower reflector as the reflector and the sun move relative to each other during the day.
