An air cooled heat exchanger is a simple pressure vessel which cools a circulating fluid within finned tubes by forcing ambient air over the exterior of the tubes.Air coolers are used in industrial applications when water source is not available.
Let's see the advantages of using air coolers:
Air is always available.
Maintenance cost normally less than for water cooled systems.
In event of power failure they can transfer some heat because of natural convection.
Mechanical design is normally simpler due to pressure on air side always being closer to atmospheric.
Fouling on air side can normally be ignored.
No problem arising from thermal or chemical pollution of cooling fluids.
