Curtain is a specialty paper honeycomb structure material, its working principle is 'water evaporation absorbs heat' of this natural physical phenomena. After the evaporation of water by gravity flow from the top down on the fiber surface wet curtain corrugated form a water film, when the fast-flowing air through the wet curtain of water in the water film will absorb heat from the air to take away a lot of latent heat of air through the wet curtain temperature decrease so as to achieve the purpose of cooling. From the 1970s, the country began the introduction of foreign advanced technology centrifugal compressor, after digestion and absorption and innovation, improved product quality. Just make sure the quality and delivery Soil Wo equipment, using the price advantage in the international arena is competitive. Especially after China's accession to WTO, to increase fan exports is entirely possible. From a historical analysis, the main export variety is small fan and fan accessories. Domestic production of such fans of enterprises, the main difference is the surface quality not up to export requirements Soil Wo fan installation telephone equipment, improve the appearance quality if Foshan soil Wo Equipment fan works, but also has a price advantage in foreign markets prospects are bright. From 1991 to 2000 the export situation fan soil Wo fan engineering equipment, small fan export is not stable enough, no clear growth trend. But as technology advances, we expected this type of wind turbine exports will continue to increase, based on the forecast in 2000 will be around 5% annual rate of increase. Centrifugal compressors and blowers from 1991 to 2000 has been significantly increased exports in 2000 reached 870,000 units. The main exporters are India, Pakistan, Iran, Vietnam and other developing countries. It is expected that this trend will develop, up to 100 million units per year.
