Abstract
Abstract A water cooling tower includes a heat and mass transfer section which is formed from a plurality of layers of multi-cell tiles and spacers between the layers of tiles. Water flows over and downwardly through the cells of the tiles and between adjacent tiles, and air is drawn upwardly through the tower to cool the water.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
In a liquid cooling tower having a plurality of vertically stacked layers of rectangular clay tiles, each of the tiles having a plurality of open cells extending vertically therethrough, each tile of each layer being offset from the tiles of the adjacent layers above and below the tile, and liquid supply means above the stacked layers of tiles for supplying liquid to be cooled to the stacked tiles whereby the liquid flows downwardly through the cells in the tiles and between adjacent tiles of a layer, the improvement comprising a layer of spacers between at least some adjacent layers of tiles for providing a vertical space between adjacent layers of tiles, said spacers having a horizontal cross sectional area less than the horizontal cross sectional area of said tiles, each of said spacers being generally rectangular and being formed from extruded clay and having a plurality of open cells extending vertically therethrough, the rectangular spacers being arranged at an angle of about 45° with respect to the rectangular tiles.
Claim 2
Dependent Claim

In a liquid cooling tower having a plurality of vertically stacked layers of rectangular clay tiles, each of the tiles having a plurality of open cells extending vertically therethrough, each tile of each layer being offset from the tiles of the adjacent layers above and below the tile, and liquid supply means above the stacked layers of tiles for supplying liquid to be cooled to the stacked tiles whereby the liquid flows downwardly through the cells in the tiles and between adjacent tiles of a layer, the improvement comprising a layer of spacers between at least some adjacent layers of tiles for providing a vertical space between adjacent layers of tiles, said spacers having a horizontal cross sectional area less than the horizontal cross sectional area of said tiles, each of said spacers being generally rectangular and being formed from extruded clay and having a plurality of open cells extending vertically therethrough, the rectangular spacers being arranged at an angle of about 45° with respect to the rectangular tiles.
Claim 3
Dependent Claim
48 words
