Abstract: Disclosed herein is a fan cylinder for a cooling tower, which is configured to prevent the air discharged from the cooling tower from flowing back thereinto. The fan cylinder is fixed to the upper side of the cooling tower, and is configured to mount a cooling fan therein. The fan cylinder comprises a linear portion having a constant inner diameter, and mounted therein with the cooling fan; an inlet portion connected at an upper end thereof to a lower end of the linear portion, and having an inner diameter increasing downwardly; an extension portion connected at a lower end thereof to an upper end of the linear portion; and having an inner diameter increasing upwardly, and an outlet portion connected to an upper end of the extension portion, and having an inner diameter decreasing upwardly.

Abstract: Disclosed is a hybrid type cooling tower. The cooling tower includes a water distributing device for distributing cooling water of a high temperature, a counterflow type filler through which the cooling water distributed from the water distributing device flows downward, an eliminator for preventing drift of the cooling air, louvers which serve as passages for allowing inflow of outside air, a fan for forcibly circulating the outside air through the cooling tower and discharging air to the outside, which air undergone heat exchange with the cooling water, and a water tank for collecting the cooling water which is chilled while flowing downward through the counterflow type filler. In the present invention, a crossflow type filler is disposed inside the louvers and under the counterflow type filler.

Abstract: An air guide for a cooling tower that prevents the air discharged from the cooling tower from flowing back into the cooling tower, and facilitates smooth circulation of outside air inside the cooling tower. The air guide is coupled to a side surface of the cooling tower, and has a length corresponding to a width of the side surface. The air guide includes an air-inflow prevention wall having a curved cross section extending downwardly and outwardly. The air guide further includes an air inlet portion defined at a lower end of the air-inflow prevention wall, and an extension portion extending from the lower end of the air-inflow prevention wall toward the cooling tower.

Abstract: Disclosed is a fill film sheet for a cooling tower. The fill film sheet has a wave-shaped section which possesses a predetermined radius when measured in an air flowing direction. The fill film sheet is made of a rectangular plate-like material having a zigzagged section which possesses a predetermined width when measured in a water flowing direction. The fill film sheet is formed with zigzagged and chevron-patterned lifts each having a first leg segment which extends toward an air outlet and a second leg segment which extends from the first leg segment toward an air inlet when measured in a downward direction. The first leg segment has a length smaller than that of the second leg segment.
