Air-cooled Heat Exchanger

Air cooler is also known as "air-cooled heat exchanger", in which ambient air is the cooling medium and fans force air to sweep across the finned tube to cool or condense the high-temperature process fluid in the tube.

Air Cooler Structure Type

Horizontal Forced-draught Air Cooling

The tube bundle is located on the exhaust side of the fan, which facilitates maintenance and overhaul, while making fan motor always in a cool air environment. It is suitable for the system with high temperature of process medium, and can effectively prolong the service life of equipment.

Horizontal Induced-draft Air Cooling

The tube bundle is located at the suction side of the fan. Because the air duct has a good effect of blocking sunlight, wind, rain and snow on the heat exchange fins, the induced-draft air cooler has a stable heat exchange performance. Besides, it has the characteristics of uniform distribution, less thermal cycle, less pollution and low noise.

Finned Tube Structure Type

Finned tube is the heat exchange element of air cooler, and its structure type directly determines the performance of the whole heat exchanger. In addition, the connection mode between fins and base tube also has great influence on heat transfer. Fins used for steel tube, aluminum tube or stainless steel tube are mainly made out of aluminum sheet, steel sheet or hot dip galvanized steel sheet.

Advantages of Air Cooler:

1. Heat transfer with air temperature rise can achieve cooling purpose and save precious water.

2. Air can be obtained freely, and the site selection is not restricted.

3. Air corrosivity is insignificant and the service life of the equipment is long.
