Abstract: A hyperboloidal cooling tower has a central post from which is suspended an upper horizontal ring centered on the post. A network of cables strung from the upper ring define a generally hyperboloidal surface, with the cables criss-crossing and the intersections clamped together with clips. A plurality of corrugated aluminum plates is secured inside the array of cables at the clips with the corrugations of the plates extending upwardly. The corrugations of each plate are spread to a greater and lesser extent at different regions along the plate together so that these plates may form a uniform three-dimensional shape. Each of the plates is secured at its central region fixedly to at least one clip and otherwise secured to the clips via stringers which can slide on these clips so as to allow thermal expansion of the plates relative to the cable network and relative to one another.
