A cooling tower is a heat rejection device / heat-transfer unit, used to remove heat from any water-cooled system. The cooled water is then re-circulated (and thus, recycled) back into the system. Think of the times you've seen something hot be rapidly cooled by putting water on it, which evaporates, cooling rapidly, such as an overheated car radiator. The cooling potential of a wet surface is much better than a dry one. The cooling towers are exposed to severe internal operating conditions such as high temperature, wet, corrosive and abrasive environments and sustained loading. FRP materials have been employed in cooling towers as secondary components (including pipes and fan stacks) for over 30 years, the primary structure traditionally being constructed from wood, concrete or steel. Consequently, the cooling tower industry has seen a rapid uptake of FRP towers in recent years. The design flexibility of FRPs has allowed new types of cooling tower to be developed which are more efficient and cost effective than previous designs and materials. The modular, cellular construction systems provide structures of high integrity that can be rapidly installed. Their inherent corrosion, moisture and temperature resistance significantly increases the durability and service life of the structure, as well as reducing the need for maintenance. FRP structures also exhibit superior dynamic response to high wind loads in comparison to conventional structural materials.
In a counter-flow cooling tower air travels upward through the fill or tube bundles, opposite to the downward motion of the water. In a cross-flow cooling tower, air moves horizontally through the fill as the water moves downward. Cooling towers are also characterized by the means by which air is moved. Mechanical-draft cooling towers rely on power-driven fans to draw or force the air through the tower. Natural-draft cooling towers use the buoyancy of the exhaust air rising in a tall chimney to provide the draft. A fan-assisted / induced draft cooling tower employs mechanical draft to augment the buoyancy effect.
