Air Cooled Heat Exchanger (ACHE)
Air Cooled Heat Exchangers are designed to condense and cool fluids in various industries. Heat exchange occurs on finned tube surfaces. Inlet and outlet header boxes feed the fluid into finned tubes. Finned tube bundles are set flat on a structure and they are blown by electrical fans and drives. The obvious advantage of ACHE is that it does not require water, thus plants requiring large cooling capacities do not have to be located close to a supply of cooling water.
Based on its configurations, ACHE can be categorized :
