What is a Cooling Tower?

Cooling Towers are heat rejection devices used for cooling water - or other working medium - to near the ambient wet-bulb air temperature. Cooling towers use evaporation of water to reject heat from processes such as cooling the circulating water used in oil refineries, chemical plants, power plants, steel mills and food processing plants.

An industrial water cooling tower extracts waste heat to the atmosphere though the cooling of a water stream to a lower temperature. Towers that use this process are called evaporative cooling towers.

The process is termed "evaporative” in that it allows a small portion of the water being cooled to evaporate into a moving air stream to provide significant cooling to the rest of that water stream. The heat from the water stream transferred to the air stream raises the air's temperature and its relative humidity to 100%, and this air is discharged to the atmosphere.

Evaporative heat rejection devices such as industrial cooling systems are commonly used to provide significantly lower water temperatures than achievable with "air-cooled" or "dry" heat rejection devices, like the radiator in a car, thereby achieving more cost-effective and energy efficient operation of systems in need of cooling.

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 industrial water cooling towers vary in size from small roof-top units to very large hyperboloid (hyperbolic) structures that can be up to 200 metres tall and 100 metres in diameter, or rectangular structures that can be over 15 meters tall and 40 meters long. Smaller towers (package or modular) are normally factory-built, while larger ones are typically constructed on site in various materials.
