Back view of cooling tower with detailing

This architectural plan is Back view of cooling tower with detailing. A cooling tower's iconic shape is known as a hyperbolic, referring to its inward curve. This makes them very stable, but to make them strong enough to last as long as they have, cooling towers have the added assistance of reinforced concrete. Cooling towers are essentially large boxes designed to maximize evaporation of water. To do this, they contain material, typically PVC plastic sheets, that create large surface areas for water evaporation to occur. This material is what fills the inside of the cooling tower and is called "Cooling Tower Fill". Cooling towers vary in size from small roof-top units to very large hyperbolic structures (as in the adjacent image) that can be up to 200 metres (660 ft) tall and 100 metres (330 ft) in diameter, or rectangular structures that can be over 40 metres (130 ft) tall and 80 metres (260 ft) long.
