Abstract
Abstract A combined direct and indirect media is disclosed which is formed from a plurality of plate-like structures. The plates are generally sheet-like elements having an indirect portion and a direct portion. The indirect portion includes a first indirect section, a second indirect section, and a hinge disposed between the first and second indirect sections. The first indirect section can be folded about the hinge to place the first and second sections in an opposed relation. The direct and indirect portions are configured to form the direct and indirect evaporative cooling media when a plurality of plates are arranged in an ordered array.
