AIR COOLED HEAT EXCHANGER:
This kind of heat exchanger are used in petrochemical and refineries to utilize the atmospheric air to cool the hydrocarbon, process and utility fluids by means of indirect heat transfer from fluid (within the tube) to be cooled by air being circulated by means of forces / induced draft fan. In order to increase the heat transfer area, fins are also attached to the periphery of tubes.

TYPES OF AIR COOLED HEAT EXCHANGER:
There are three types of air cooled heat exchanger:

a)Forced Draft

b)Induced Draft

c)Natural Draft (used for applications like transformer oil cooling)
