Title: Method of fabricating a solar absorber panel

Patent ·
OSTI ID:5201796

A low-cost method of fabricating a solar absorber panel for use with a flat plate solar collector system is disclosed in which a plurality of formed elongated substantially u-shaped members are fixed in a predetermined configuration to the reverse side of a single sheet absorber member forming therewith hollow fluid passages or ducts. The fluid duct members are provided with a series of tabs which alternately protrude through spaced slits in the absorber panel such that when the tabs are folded over, a tight interlocking construction is produced. The ends of the single sheet absorber may then be folded to form inlet and outlet manifolds connecting the ends of the series of spaced ducts including closing end tabs or the manifolds may be fabricated of u-shaped tabbed members in the manner of the connecting passages. After the mechanical assembly, the entire unit is sealed as by pumping liquid solder under pressure through the unit. This not only seals the system but also provides a corrosion-resistant coating of solder over all internal parts.
