Abstract
A wet deck fill sheet is disclosed for use in making a wet deck fill for use in evaporative counterflow heat exchangers. One aspect of the sheet is that it includes transverse corrugations formed in at least one of the top and bottom edges of the sheet. Another aspect is the provision of a staggered array of substantially vertical spacers extending from one face of the sheet to space the sheet a predetermined distance from an adjacent sheet in the wet deck fill. The spacers are aligned to provide for substantially equalized air flow along the length of the sheet in a horizontal direction between the sheets as the air travels upward through the deck. Another aspect of the invention includes providing in the sloping walls of the major face corrugations formed in the fill sheets a plurality of substantially horizontal air turbulence increasing and water spreading means to increase the interaction of air and water to provide improved thermal performance.
