Most towers have structural frames that support the exterior enclosures (casings), motors, fans, and other components. With some smaller designs, such as some glass fiber units, the casing may essentially be the frame.

This is the point of entry for the air entering a tower. The inlet may take up an entire side of a tower (cross-flow design) or be located low on the side or the bottom of the tower (counter-flow design).

Air cooled Heat Exchangers (or) Fin fan Cooler or Air Fin Cooler are used for Heat rejecting from a hot process fluid to the surrounding atmosphere by using the atmospheric air as a cooling media.

What is Air Finned Coolers?The Air Fin Coolers are basically designed with multiple rows of finned tubes in a series of surface and required numbers of fans are used to move the low temperature atmospheric ambient air over the finned tube coil surface in order to cool the hotter fluid media
The various types of headers are Welded Bonnet Header, Plug Header, Manifold header, Plug and pipe header etc., The various types of Fins are 'L' type Wrap-On Fins, 'G' type Embedded Fins and Bi-metallic Extruded Fins etc. In some small type heat Exchanger wire/ strip type copper wounded / knurled Fins are also used.
These Air Cooled Type Heat Exchangers are used in oil, gas, petrochemical, refinery, power and condensation plants. All type of fluids in process industries are cooled in Air Fin Coolers with the use of atmospheric air, as the cooling media which resulting in economy in running costs.

Components of Air Finned Coolers
Air Fin Coolers consist of number of bays. Each bays consists of the following major equipment:

• Heat Exchangers Fin Tube Bundles.  
• Supporting structure for the Tube Bundles
• Fan arrangement with Gear Box and Motor or Belt & Pulley Drive.
• Piping with valves and instruments as per the requirement etc.

What is a cooling tower?Cooled water is needed for, for example, air conditioners, manufacturing processes or power generation. A cooling tower is an equipment used to reduce the temperature of a water stream by extracting heat from water and emitting it to the atmosphere. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly. Cooling towers are able to lower the water temperatures more than devices that use only air to reject heat, like the radiator in a car, and are therefore more cost-effective and energy efficient.

Components of a cooling towerThe basic components of a cooling tower include the frame and casing, fill, cold-water basin, drift eliminators, air inlet, louvers, nozzles and fans. These are described below.
Frame and casing. Most towers have structural frames that support the exterior enclosures (casings), motors, fans, and other components. With some smaller designs, such as some glass fiber units, the casing may essentially be the frame.

TYPES OF COOLING TOWERSThis section describes the two main types of cooling towers: the natural draft and mechanical draft cooling towers.
Mechanical draft towers are available in a large range of capacities. Towers can be either factory built or field erected – for example concrete towers are only field erected.
Many towers are constructed so that they can be grouped together to achieve the desired capacity. Thus, many cooling towers are assemblies of two or more individual cooling towers or “cells.” The number of cells they have, e.g., a eight-cell tower, often refers to such towers. Multiple-cell towers can be lineal, square, or round depending upon the shape of the individual cells and whether the air inlets are located on the sides or bottoms of the cells.

The three types of mechanical draft towers

• Type of cooling tower
• Forced draft cooling tower: air is blown through the tower by a fan located in the air inlet
• Induced draft cross flow cooling tower water enters at top and passes over fill, air enters on one side (single-flow tower) or opposite sides (double-flow tower) , an induced draft fan draws air across fill towards exit at top of tower
• Induced draft counter flow cooling tower, hot water enters at the top, air enters bottom and exits at the top, uses forced and induced draft fans.

The cold-water basin is located at or near the bottom of the tower, and it receives the cooled water that flows down through the tower and fill. The basin usually has a sump or low point for the cold-water discharge connection. In many tower designs, the cold-water basin is beneath the entire fill. In some forced draft counter flow design, however, the water at the bottom of the fill is channeled to a perimeter trough that functions as the cold-water basin. Propeller fans are mounted beneath the fill to blow the air up through the tower. With this design, the tower is mounted on legs, providing easy access to the fans and their motors
