Structural principle

Air cooled heat exchanger (referred to as air cooler) is a large-scale industrial heat exchange equipment that uses natural air to cool or condense process hot fluids. Compared with water cooling, it has the advantages of sufficient and free cold source, saving cooling water, reducing environmental pollution, and low maintenance costs,

Air coolers are generally composed of heat exchange tube bundles, frames, fans, and accessories. According to the ventilation method, it can be divided into blower type and induced draft type; According to the cooling method, it can be divided into dry and wet types; According to the installation form of the tube bundle, it can be divided into horizontal, inclined top, vertical, and inclined vertical combined types.

scope of application

Air coolers are widely used in various working conditions that require cooling or condensation, such as petroleum refining, electricity, steel metallurgy, and chemical engineering.
