ABSTRACT:
Flat plate absorber member includes a flat heat absorbing sheet of a thin metal foil such as copper, or a thin plastic film such as polyvinyl fluoride, bonded to a channeled substrate, and particularly to a plastic laminate such as a glass epoxy laminate. The improved absorber member provides an energy collecting efficiency which is much greater than that of a much more expensive conventional collector having a series of copper tubes soldered to a copper sheet. The absorber is preferably made by the method of taking a base sheet of fully cured glass epoxy laminate and overlying it with a precut, patterned intermediate layer of semi-cured glass epoxy which defines the depth of the side walls of the channels. The cover sheet of metal foil or plastic film is then placed over the semi-cured glass epoxy intermediate layer and heat and pressure are applied to bond the semi-cured glass epoxy to the cover sheet and to the previously cured base sheet.
