Abstract:
1. A sound attenuation apparatus for a heat exchange tower having heat exchange fluid which falls in a generally downward direction along a vertical axis into a collection basin, comprising: a heat transfer media positioned at a first vertical height along the vertical axis; at least one sound attenuation fill pack having an upper end and a lower end, wherein said at least one sound reduction fill pack comprises a plurality of film sheets, each of said sheet having a fist region at the upper end with a first surface at a first angle substantially equal to 0° to the vertical axis direction, wherein said at least one sound attenuation fill pack is positioned as a second vertical height along the vertical axis below said first vertical height, wherein each of said plurality of sheets is connected to one another so that said at least one sound attenuation fill pack is sight tight; and a support structure that supports said at least one sound attenuation fill pack, wherein said lower end of said at least one sound attenuation fill pack is positioned above the liquid collection basin, wherein said at least one sound attenuation fill pack is utilized in combination with said heat transfer media and wherein said at least one sound attenuation fill pack is positioned between the heat transfer media and the liquid collection basin along the vertical axis so that a vertical space exists between said heat transfer media and said at least one sound attenuation fill pack; and wherein said plurality of film sheets each comprises a second region having a second surface joining said first surface and at a second angle to the vertical axis different from the first angle, a third region joining the second region having a third surface and a third angle to the vertical axis different from the second angle, a fourth region joining the third region and having a fourth surface and at a fourth angle to the vertical axis different from the third angle. and a fifth region joining the fourth region having a fifth surface and at a fifth angle to the vertical axis different from the fourth angle.
