Air Cooled Heat Exchanger Air-cooled heat exchangers (ACHE), also known as fin fan heat exchangers or air coolers, are a type of heat exchanger that uses air to cool a fluid, often in industries where water is scarce or expensive. Unlike other types of heat exchangers, such as shell and tube or plate heat exchangers, ACHEs do not require a secondary fluid temperature to remove heat; instead, they rely on ambient air. This characteristic makes them especially valuable in water-scarce areas or in applications where minimizing water use is a priority. https://www.heatexchanger.co.in/Heat-Exchanger/Air-Cooled-Heat-Exchanger/
