Abstract: A sandwich structure is provided that includes a corrugated layer with at least one core layer (structure) made of a periodic array of adjacent truncated upward facing peaks and truncated downward facing valleys. Each truncated peak has a bonding land of an area A1. Each truncated valley has a bonding land of an area A2. A ratio of A1/A2 is less than 2. A distance D is between neighboring peaks, and a distance D is also between neighboring valleys. The corrugated layer is made from an initially flat sheet thickness of t. A first sheet layer is physically coupled to bonding lands of the truncated peaks. A second sheet layer is physically coupled to bonding lands of the truncated valleys.

Abstract: Methods and apparatus for transmitting a fluid through the core of a metal sandwich structure. Improved metal sandwich sheet structures include a formed metal core that is brazed, welded, or bonded to two outer flat metal sheets at a series of interleaving surface regions. The inventor has recognized that fluids (e.g., liquid and/or gaseous substances) can be transmitted through the cavities of these structures in order to accomplish thermal conduction or as a means of servicing particular regions of a building, vehicle, device, or other work of construction.
