Air Coolers Fin-Fan Coolers

Air coolers are twice as expensive to purchase and install as water coolers. The great advantage of an air cooler is that it does not need cooling water. The difficult aspect of air cooling arises from the flow of air across the tubes.

Most air coolers are either induced-draft or forced-draft, as shown in Fig. 17.1, the more common arrangement being forced draft. The air is moved by rather large fans. The tubes are surrounded with foil-type fins, typically 1 in high. The surface area of the fins as compared to the surface area of the tubes is typically 12 to 1. That is why we call an air cooler an extended-surface heat exchanger.
Figure 17.1: Two types of air coolers.

The heat-transfer coefficient of an air cooler (Btu, per hour, per square foot of finned area, per degree Fahrenheit) is not particularly good. It might be 3 to 4 for cooling a viscous liquid, or 10 to 12 for condensing a clean vapor. The low heat-transfer coefficients are offset by the large extended surface area.

Air cooled Heat Exchangers (or) Fin fan Cooler or Air Fin Cooler are the same Air Cooling equipment. In some part of the world Air Cooled Heat Exchangers are also known as Air Fin Cooler. Simply says Air Fin cooler, Fin Fan cooler, Coil Cooler, Dry Cooling Tower are the other names of Air Cooled Heat Exchangers. It also used for Heat rejecting from a hot process fluid to the surrounding atmosphere by using the atmospheric air as a cooling media.

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. It is nothing but an extended type of industrial or automotive radiators. The finned tube bundles are modular construction for easy transportation. 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. Other than finned tube bundle and headers, Axial flow fans and drives etc are used as per the Cooler requirement.

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.

Our Air Cooled Heat Exchangers are used for high pressure, high temperature applications in process industries with metallurgy suitable for highly corrosive fluid medias.

Best Fin Fan Cooler Manufacturer in India - Enginemates Heat Transfer Pvt Ltd

A fin fan cooler is a term used to refer to an aerial cooler. I believe at one time a specific manufacturer called their coolers "Fin-Fans" and the term later came to be a reference to any aerial cooler. Much the same was as electric refrigerators were all referred to as Frigidaire's or copies are referred to as XEROX's.

This type of aerial cooler is used a great deal in refinery and petro chemical plants. The construction usually consists of two metal rectangular boxes with drilled holes to accept hollow tubes that have aluminum fins attached to them.

For those familiar with a car radiator, the concept is the same. The difference is Fin Fan Cooler Manufacturer construction needs to be more robust because the pressure contained by the coolers is usually much higher than that of a car radiator.

The two boxes (called headers) with the interconnecting tubes are housed in a light metal plenum that directs air from one or more fans over the finned tubes to achieve the desired cooling.

This is a simplified description of an aerial cooler. There are many details regarding fabrication, configuration, materials, fan design etc. that I have left out.

The heat-transfer coefficient of an air cooler Aluminum Radiator (Btu, per hour, per square foot of finned area, per degree Fahrenheit) is not particularly good. It might be 3 to 4 for cooling a viscous liquid, or 10 to 12 for condensing a clean vapor. The low heat-transfer coefficients are offset by the large extended surface area.

In a forced-draft air cooler, cool air is blown through the underside of the fin tube bundle. In an induced-draft air cooler, cool air is drawn through the underside of the fin tubes. Either way, road dust, dead moths, catalyst fines, and greasy dirt accumulate along the lower row of tubes. As the tubes foul, they offer more resistance to the airflow.

Fin Fan Cooler – The Importance

Generally designed for outdoor-use but these coolers can actually be used in a lot more than one place if required in the future. There are many ways through which individuals can acquire both direct and indirect cooling, but one of the best and the most effective ways to do so is by investing in a fin fan cooler. These types of coolers have gained a huge amount of importance over the past few years due to the amazing range of benefits they have to offer in not only the short, but the long run as well.

No Sound Emission

Another major benefit of such coolers is that they hard make any sound. Even if they do, the sound levels can always be reduced. While other cooling devices are known to make a lot of noise on a day to day basis, a fin fan cooler is something that keeps the external environment peaceful whenever required. Due to this fact, it is much better in comparison with many of its opponents, such as air conditioners, for that matter. Investing in these coolers really pays off when no loud and continuous sounds come through it, especially at the time of the night when everyone requires silence.

Easy to Install

The installation of a fin fan cooler is rather easy in general. While a lot of people may think that it should take up a lot of time, it really does not and can be winded up quite soon. Asking properly installers in order to carry out the job is hardly expensive and gets the job done within a day’s time; hence, it is quite recommended. On the other hand, these coolers can be used for both residential as well as commercial use. Therefore, people can always decide whichever they prefer more. With a wide range of different kinds of such coolers present these days, it is very important to choose the right one that fulfills a task at hand.

Long-term Durability

These coolers are available on sale in the market as well as at numerous online stores in different parts of the world. Before purchasing them, individuals should be aware of all that they have to offer. These coolers are highly durable and can last for a long period of time without getting deteriorated. Most importantly, these coolers are better suited for high pressure usage, such as with gas engines and everything as such, when it comes to industrial and commercial usage. Hence, people should keep this important information in mind.

Cooling Spacious Areas

A major reason for investing in a fin fan cooler is the fact that it allows the overall surroundings to become cooler in general. A lot of other machines and devices have been made to carry out this task but these cooler stands out due to this impressive performance and high end features. Moreover, they can cool down large spaces within a short period of time. Generally available easily on sale these days, individuals should not let go of this exclusive source for direct cooling whenever required. These can be installed anywhere, according to the preference of an individual.

Removal of Dust Particles

A fin fan cooler is also known to completely eliminate the entire amount of dust from the air. This makes it a very suitable equipment to purchase as everything requires clean and fresh air to breath in at all times. Dust particles can be found in abundance in the air and in order to remove them, these coolers prove to be rather handy and very useful in both the short and long run. The existence of dust in the air, if not removed quickly, can lead towards many illnesses, diseases as well as allergies that can deteriorate anyone’s condition. Hence, these coolers are most definitely worth buying.
