A plastic laminate form of heating panel incorporating a layer of a semiconductive carbonaceous pyropolymer, consisting of carbon and hydrogen on a high surface area refractory inorganic oxide support, with the conductive pyropolymer positioned to at least one side of at least one laminate layer and a reflective metallic layer on the other side thereof such that radiant heat is controlled and directed outwardly in a desired manner to minimize energy being wasted by a 'rearward' flow.

Radiant heating panel

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 overlaying it with a precut, patterned intermediate layer of semi-cured glass expoxy 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.

Method of making laminated absorber member for flat plate collector

Metal-clad laminates in which the metal coating of the laminate is only from about 1 micron to about 20 microns in thickness are prepared by depositing a copper coating on a substrate which has been treated with a release agent, treating the upper side of the metal layer to improve the adhesive properties of the metal, thereafter bonding the metal coating to a laminate and removing the substrate to thus prepare the desired metal-clad laminate.
