Air cooled condenser is a heat exchange device that uses air as a cooling medium and is widely used in refrigeration, air conditioning, and industrial cooling systems. The core principle is to use a fan to force air to flow through the condensing coil, taking away the heat of the high-temperature and high-pressure gaseous refrigerant and condensing it into a liquid state. Compared to water-cooled condensers, air-cooled condensers do not rely on cooling water systems and have advantages such as compact structure, easy installation, low maintenance costs, and water conservation and environmental protection. They are particularly suitable for areas with water scarcity or poor water quality. Typical structures include copper tubes, aluminum finned coils, axial fans, motors, and metal casings. By optimizing fin design and duct layout, heat transfer efficiency can be improved. Although it has limitations such as slightly high noise and significant influence from environmental temperature, its high reliability and strong adaptability make it an important player in the fields of small and medium-sized refrigeration equipment, cold chain logistics, and commercial air conditioning.
