The vertical height requirement of a cooling tower is reduced by utilizing trapezoidal shaped fill sheets which are suspended generally in line with the entering air stream so as to form a wedge shaped plenum space beneath the lower sloped edges of the fill sheets. This enables a method of lengthening the vertical air paths through the media as distance from entry is increased thereby promoting vertical air flow near the entry.

An improved counterflow cooling water tower comprising: an enclosure having vertical walls including one wall with an air inlet in a lower portion thereof and a second wall opposite said one wall; a plurality of heat transfer media extending across said enclosure from about said one wall to about said second wall so as to form a plurality of parallel air passageways, said passageways being aligned with said air inlet and perpendicular to said one wall, each of said media having an upper extremity extending in a horizontal substantially straight line above said air inlet from about said one wall to said second wall, each of said media also having a lower extremity sloping downwardly in one direction from said one wall above said air inlet along a substantially continuous line to about said second wall whereby to define a plenum space inward of said air inlet, said plenum space having an interface with the lower extremity of said media which slopes continuously downwardly in one direction from said one wall to said second wall. An improved method for moving air through a counterflow cooling tower, said method comprising: forming an enclosure having vertical walls including one wall with an air inlet in a lower portion thereof and a second wall opposite said one wall; placing heat transfer media within said enclosure to define a plenum space between said air inlet and said second wall, said media extending across said enclosure between said one wall and said second wall so as to form a plurality of parallel air passageways aligned with said air inlet and perpendicular to said one wall; maintaining each of said media in a vertical altitude with an upper extremity extending in a horizontal substantially straight line between said one wall and said other wall and a lower extremity extending from said one wall above said air inlet along a substantially continuous downwardly sloped line to said second wall whereby said plenum space interface with said media slopes continuously downwardly in one direction from a top of said air inlet; and moving air horizontally into said plenum space through said air inlet toward said second wall and causing portions of the horizontally moving air to move upwardly through said passageways from points where said horizontally moving air reaches said interface whereby the vertical path and resistance to flow of air in said air passageways is increased as the horizontal distance from said one side is increased and thereby causing a relatively greater rate of vertical air flow near said one side.
