What is a fin fan air cooler?
Fin Fan Cooler is a kind of heat exchanger that uses the air for cooling medium. It is required a wide surface area for heat transfer. It is applied to finned tube for increasing the heat transfer surface and compact design of construction area.
What is a fin fan?
A Fin Fan is a type of heat exchanger that moves air over the finned tubes of a dry cooler that hot fluid passes through. (The most common way of regulating the air movement is with a variable speed fan.)
What is a fin fan motor?
A fin fan is an air-cooled heat exchanger. Instead of dissipating heat into water and then transferring that heat to the air, as with shell and tube heat exchangers and wet cooling tower systems, a fin fan dissipates heat from a fluid directly into the air. Both forced and induction fans are used at the DuPont plant.
When should I use an air cooled heat exchanger?
Air cooled heat exchangers, also known as Fin Fan heat exchangers, are typically used in applications where water is not available or the desired process outlet temperature can be achieved given the maximum ambient temperatures.
How is water cooled in a cooling tower?
A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water’s temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower.
What is an air fin heat exchanger?
Air Cooled Exchangers Air cooled heat exchangers, also known as Fin Fan heat exchangers, are typically used in applications where water is not available or the desired process outlet temperature can be achieved given the maximum ambient temperatures.
What are the two types of heat exchangers?
There are two main types of regenerative heat exchangers—static heat exchangers and dynamic heat exchangers.
What is air cooled exchanger?
Air Cooled Heat Exchanger (ACHE) is a heat rejection equipment where the excess process heat is rejected to the atmosphere. It works on the principle of convection and conduction to dissipate heat from process fluid to air.
Why are fins installed on electric motor?
The fins are usually mounted on an electric motor outer surface, which is its housing. Its function is to increase heat transfer rate by natural convection. The fans are used to increase heat transfer rate by forced convection.
How does a fin fan heat exchanger work?
A Fin Fan Heat Exchanger, is a type of heat exchanger used to cool different processes in the refining, petrochemical, and chemical processing industries. Using a series of fans, fin fan coolers move low temperature atmospheric ambient air over multiple rows of finned tubes in order to cool internal process fluids.
Do cooling towers pollute?
It is, of course, clean water vapor that results from the cooling process. It contains no pollutants, and it is not radioactive – the nuclear process takes place inside a secure containment building, not the cooling tower.
What is the other name of air fin cooler?
In some part of the world Air Cooled Heat Exchangers also known as Air Fin Cooler. Simply says Air Fin cooler, Fin Fan cooler, Coil Cooler, Dry Cooling Tower the other names of Air Cooled Heat Exchangers.
What is a Fin fan heat exchanger?
A fin-fan is a type of heat exchanger that forces air over a set of coils to cool the process. It is also referred to as an air cooled heat exchanger. Fin-fan heat exchangers are generally used where a process system generates heat which must be removed, but for which there is no local use.
What are the codes and standards for air Fin fan coolers?
Codes and Standards for air-cooled exchanger Design The following codes and standards govern the design of air fin fan coolers. API 661 / ISO 13076 (Air-cooled heat exchangers for general refinery service) ASME SECT.VIII Div.1 or Div.2
What are the common types of Fin fan cooler corrosion?
During gas dehydration process, all parts of fin fan coolers suffer from different types of corrosion such as sweet (CO 2) corrosion, dew-point corrosion, high temperature corrosion, and erosion.
