Cooling towers are a special type of heat exchanger that allows water and air to come in contact with each other to lower the temperature of the hot water. During this process, small volumes of water evaporate, lowering the temperature of the water that's being circulated throughout the cooling tower.

A cooling tower is a heat rejection device, which extracts waste heat to the atmosphere though the cooling of a water stream to a lower temperature. ... Common applications for cooling towers are providing cooled water for air-conditioning, manufacturing and electric power generation. for more info visit: https://toppostaboutcoolingtower.mystrikingly.com/
