Research On Wet Style Air Cooler

Water-cool and air-cool are two kinds most important cooling methods for current industrial units. The development of air-cool technology and device can meet demands of saving water, protecting the environment and saving energy. The air cooler which uses air-cool technology is a very important device of industrial production.This thesis introduces the components of air cooler such as tube bundle, framework, blower, shutters. The cooling capability of dry-style air cooler is effectted more by environmental air temperature. Considering energy consumption, water consumption, plane layout, performance and economical efficiency, wet-style air cooler is more advantages than dry-style air cooler. Design calculations are done for wet-style air cooler with heat transferming mechanism, air inlet temperature after spray, air oytlet temperature, choice of water spray amount, heat transferring coefficient, air lateral pressure loss and design calculation procedures. At the same time, some important problems of air cooler design are analyzed and explained, including finned tube paremeter optimization, anti-freeze design of air cooler, saving energy of air cooler, noise vibration and control. The applications of air cooler are enumerated in industries.Finally, the prospect of air cooler is made out. Plate type air cooler is promising.
