Abstract: A tornado protected cooling tower. The tower includes a plurality of enclosed cooling cells arranged about the periphery of an open cooling basin. Each of the cells includes a cool air inlet along the side thereof opposite the open cooling basin and a warm air outlet along the side thereof adjacent the open cooling basin. A plurality of fans are mounted within each of the cells along the side thereof adjacent the open cooling basin in direct communication with the warm air outlet. Each of the cells further includes an inner wall having an apron portion extending downwardly below the lowest component of the fans. Water distribution means is provided for carrying water upwardly from the open cooling basin into each of the cells for discharge in uniformly dispersed fashion within the cell. Each of the cells includes a perforate fill material supported by fill support means below the water distribution means and above the cool air inlet.
