Abstract
A fill sheet for cooling heat transfer fluid in a cooling tower includes an air intake end, an air outlet end, a top edge and a bottom edge. The air outlet end is positioned opposite the air intake end along a lateral axis. The top edge connects the air intake end and the air outlet end and the bottom edge also connects the air intake end and the air outlet end. The bottom edge is positioned opposite the top edge along a vertical axis. A plurality of flutes extends generally parallel to the lateral axis between the air intake end and the air outlet end. An offset extends generally parallel to the vertical axis. A first flute of the plurality of flutes transitions from a first peak at a first side of the offset to a first valley at a second side of the offset.
Claims25
A fill sheet for cooling a heat transfer fluid in a cooling tower when assembled into fill packs comprised of pluralities of fill sheets for use in a cross-flow cooling tower, the fill sheet comprising:
- an air intake end;
- an air outlet end positioned opposite the air intake end along a lateral axis;
- a top edge connecting the air intake end and the air outlet end;
- a bottom edge connecting the air intake end and the air outlet end, the bottom edge positioned opposite the top edge along a vertical axis, the heat transfer fluid configured for flowing between the top edge and the bottom edge;
- a plurality of flutes extending generally along the lateral axis between the air intake end and the air outlet end;
- and
- a transition feature providing a flat section of macrostructure extending generally parallel to the vertical axis, a first flute of the plurality of flutes transitioning from the flat section of the transition feature, the flat section including a rib extending generally parallel to the vertical axis and a spacer proximate to the rib to provide lateral support for the rib.
A fill sheet for cooling heat transfer fluid in a cooling tower when assembled into fill packs comprised of pluralities of fill sheets, the fill sheet comprising:
- an air intake end;
- an air outlet end positioned opposite the air intake end along a lateral axis;
- a top edge connecting the air intake end and the air outlet end;
- a bottom edge connecting the air intake end and the air outlet end, the bottom edge positioned opposite the top edge along a vertical axis;
- a microstructure formed on the fill sheet;
- and
- a support rib extending between the top edge and the bottom edge, the support rib including a first support rib and a second support rib, the first and second support ribs spaced laterally from each other along the lateral axis and extending substantially parallel to the vertical axis, the support rib having a first support rib portion having a first support rib length, the first support rib including a first rib height and the second support rib including a second rib height, the microstructure having a microstructure height, the first rib height being less than the microstructure height in the first support rib portion and the second rib height being greater than the microstructure height in the first support rib portion.
