ABSTRACT:
A wall assembly consisting of at least an upper, an intermediate and a lower sheet of a rigid material, each sheet being poked with a plurality of similar protuberances and cavities extending on opposite sides of the virtual plane defined by the sheet in alternating fashion, whereby each cavity is surrounded solely by protuberances and each protuberance is surrounded solely by cavities. The sheets are glued to each other in superimposed fashion. Gaps are defined between the sheets, wherein an upper and a lower layer of undulating channels are defined thicknesswisely of the wall assembly. The wall assembly may be used as a structural wall or panel or as a heat exchanger, wherein the channels are arranged in two sets for the passage of two different fluids whereby thermal exchanges therebetween may occur.
