Phenolic laminate solar absorber panel and method of making
A solar flat plate absorber panel is molded from a laminate consisting of a suitable web material impregnated with a thermosetting phenolic resin. The absorber plate is pressure formed from superimposed layers of material and mold-cured to produce a unitary structure having a first or solar radiation absorbing surface on one side and an integral closed hollow lattice work of fluid heat transfer passages on the other or reverse side of the panel. The laminate web may be made from any suitable material such as paper, cloth, canvas, or wire mesh which is easily impregnated with a thermosetting phenolic resin. In the preferred embodiment a B-stage phenol-formaldehyde resin is used. The two superimposed sheets of impregnated material are molded between heated platens of an hydraulic press to form an integral structure and fluid pressure between the sheets is utilized to mold the desired passage shape 5.
