Air Cooled / Fin Fan Air Cooler

An air cooled , or ACHE or Fin tubes exchanger, is simply a pressure vessel which cools a circulating fluid within finned tubes by forcing ambient air over the exterior of the tubes. A common example of an air cooler is a car’s radiator.

Air cooled heat exchangers are used for two primary reasons:

  • They increase plant efficiency
  • They are a “green” solution as compared to cooling towers and shell and tube heat exchangers because they do not require an auxiliary water supply (water lost due to drift and evaporation, plus no water treatment chemicals are required).

Headers Type :

In combination with the finned tubes, headers are an integral part of the air cooled heat exchanger pressure vessel. Headers are used to receive the fluid from the piping and direct the fluid through the tubes. Tubes are connected to the headers via expanding, welding or both. A few of our standard header configurations are:

  • Shell : » Plug Box Header » Cover Plate Header » Pipe Manifold

TSF is capable of fabricating all types of headers and bundle configurations, each offering their own benefits and serving all of the process and power applications.

Finned Tubes :

The efficiency of air-cooled heat exchangers primarily depends on the heat transfer capabilities of the finned tubes. Important factors to be considered include design temperatures, operating environment and whether or not the cooler will be exposed to cyclical service.
