Abstract:
A sinuous pattern of soft copper tubing is pressed against a laminated assembly consisting of a thin sheet of copper laminated to a layer of insulating foam which is in turn laminated to a backing plate of pressed wood. As the pressure is increased, the tubing deforms the copper sheet in conformity with the shape of the copper tubing. The foam resists deformation of the sheet in areas not directly beneath the copper tubing resulting in a well-defined trough adapted to receive the copper tubing which deforms it. The copper tubing and sheet are then bonded together resulting in a thermally efficient, inexpensively produced collector panel.
