Bi-directional fill for use in cooling towers
Cooling towers and cooling tower fill configured for the cooling of process water with air by indirect heat exchange, in which the fill is configured with a first set of channels and a second set of channels, said first and second set of channels interleaved with one-another so that heat exchange occurs across material separating said channels from one-another.
1. A cooling tower comprising cooling tower fill arranged for the cooling of process water with air by indirect heat exchange, in which the fill is configured with a first set of channels and a second set of channels, said first and second set of channels interleaved with one-another so that heat exchange occurs across material separating said channels from one-another, in which said channels are created by one or more fill packs, each fill pack comprising layers of stacked corrugated sheets, each corrugated sheet having a longitudinal axis that is shifted 30° to 90° relative to a longitudinal axis of adjacent corrugated sheets, each corrugated sheet separated from an adjacent corrugated sheet by an intermediate sheet, said cooling tower further comprising omnidirectional fill arranged between said fill packs.
2. A cooling tower comprising cooling tower fill arranged for the cooling of process water with air by indirect heat exchange, in which the fill is configured with a first set of channels and a second set of channels, said first and second set of channels interleaved with one-another so that heat exchange occurs across material separating said channels from one-another, in which said channels are created by one or more fill packs, each fill pack comprising layers of stacked corrugated sheets, each corrugated sheet having a longitudinal axis that is shifted 30° to 90° relative to a longitudinal axis of adjacent corrugated sheets, each corrugated sheet separated from an adjacent corrugated sheet by an intermediate sheet, wherein internal intermediate sheets have beveled corners to allow fluid or air communication to isolated areas of said fill pack.
3. A cooling tower comprising cooling tower fill arranged for the cooling of process water with air by indirect heat exchange, in which the fill is configured with a first set of channels and a second set of channels, said first and second set of channels interleaved with one-another so that heat exchange occurs across material separating said channels from one-another, wherein said first set of channels are oriented parallel to a first edge of said fill from a top of said fill to a bottom of said fill, and wherein said second set of channels are oriented diagonally relative to said first edge of said fill for a distance of one channel width beginning at a topmost section of said fill, and are oriented parallel to said first edge of said fill through a middle section of said fill.
4. A cooling tower comprising cooling tower fill arranged for the cooling of process water with air by indirect heat exchange, in which the fill is configured with a first set of channels and a second set of channels, said first and second set of channels interleaved with one-another so that heat exchange occurs across material separating said channels from one-another, wherein said first set of channels are oriented diagonally relative to a first edge of said fill for a distance of one-half channel width in a first direction at a topmost section of said fill, are oriented parallel to said first edge of said fill through a middle section of said fill, and wherein said second set of channels are oriented diagonally relative to said first edge of said fill for a distance of one-half channel width in a second direction at said topmost section of said fill, and are oriented parallel to said first edge of said fill through a middle section of said fill.
