Advantages and application of air cooler
Air cooler is a kind of heat exchange equipment to cool the fluid. Water or air is usually used as a coolant to remove heat.
The use of air cooler can save a lot of industrial water, reduce pollution, protect the environment and reduce infrastructure costs. In order to expand the application range of air cooler, the humidified air cooler appeared in the 1960s, that is, adding water spray device in front of the tube bundle, and using the evaporation of a small amount of atomized water on the surface of fins, the heat transfer efficiency is increased by 2-4 times than that of dry type air cooler. The humidified air cooler has been widely used in refineries. Dry air cooling tube bundle and wet air cooling tube bundle can also form combined air cooler. The development of air cooler depends on the development of finned tube with low contact thermal resistance and high heat transfer efficiency, and a fan with low power consumption and low noise.
The air cooler includes wall cooler, spray cooler, jacket cooler and snake tube cooler. Air cooler can be used for cooling or condensing. It is widely used in the condensation of overhead steam of refining and petrochemical tower, the cooling of return oil and tower bottom oil, the cooling of various reaction products, the cooling of circulating gas and the condensation of exhaust gas of steam turbine in power station.
