Fanless Cooling Tower

Fanless Cooling Towers is a design in which the flow is directed perpendicular to the water. The air continues through the fill and thus past the water flow into an open plenum volume. A fan forces the air out into the atmosphere. Air flow enters one or more vertical faces of the cooling tower. Water flows through the fill by gravity.

• Fanless Cooling Towers designs are popularly associated with nuclear power plants. The same kind of cooling towers are often used at large coal-fired power plants. Some instead cool their heat exchangers with lake, river or ocean water.

• Fanless Cooling Towers leaves its dissolved salts behind in the bulk of the water which has not been fanless, thus raising the salt concentration in the circulating cooling water.

• Fanless Cooling Towers absorbs heat from the hot process streams which need to be cooled or condensed, and the absorbed heat warms the circulating water.
