Air cooled heat exchanger

Typically, an air-cooled heat exchanger for process use consists of a finned-tube bundle with rectangular box headers on both ends of the tubes. Cooling air is provided by one or more fans. Usually, the air blows upwards through a horizontal tube bundle. The fans can be either forced or induced draft, depending on whether the air is pushed or pulled through the tube bundle. The space between the fan(s) and the tube bundle is enclosed by a plenum chamber which directs the air. The whole assembly is usually mounted on legs or a piperack.


The air cooled heat exchanger (air cooler)uses natural wind as the cooling medium to save water resources, reduce the discharge of industrial sewage, and protect the environment. Widely used in petrochemical, electric power, metallurgy and other industries.
