With the development of industry in the north-west of China, the demand for water from various industrial enterprises is increasing, while the problem of water shortage is attracting more and more attention (zhòng shì). The cross-flow closed cooling tower uses steel plates as the main structure and an additional steel frame inside. The product is of double fan construction, while the double fans are driven by the same motor via belt reducers. The difference between this product and the cross-flow FRP cooling tower is the very different coils and fillers and the fully enclosed operation of the circulating water. Water resources are relatively scarce in the Northwest, so choosing (xuanze) effective energy and water conservation measures (meaning solutions to problems) is essential to protect the limited water resources in the Northwest and to maintain sustainable social development.
　　With the development of industry in Northwest China, the demand for water from various industrial companies is increasing, while the problem of water shortage (Emerson) is attracting more and more attention (zhòng shì). The relative scarcity of water resources in the North West region means that the selection of effective energy and water saving measures (solutions to problems) is of great importance in protecting the limited water resources in the North West region and maintaining sustainable development in society.
　　The cooling tower is a device (shèbèi) that uses dry cooled air (AIR) as the cooling medium to cool or condense the high temperature fluid in the tube, without the problem of water consumption in the operation of the system, and with low energy consumption in the operation process (guò chéng). jieneng) water-saving equipment. The average temperature in the Northwest is low in all seasons and the climate is dry (lack of moisture), so a reasonable application of cooling towers will achieve good economic performance and social benefits.
　　Design and production (Produce) of cooling (cooling) tower, with convenient operation control (fāng biàn), stable operation and other characteristics, can be widely used in petrochemical, chemical, smelting metal, power station and other related industries (Industry). High efficiency closed cooling tower adopts multi-group coil structure, multi-group coils are installed at the two ends of the closed cooling tower air inlet surface. The coil and the heat exchanger filler are staggered in design, the spray water is cooled by the heat exchanger filler after passing through the coil, and flows into the bottom water collection tray after repeatedly. The heat exchanger coils are generally made of copper tubes, but in special cases they can also be made of stainless steel or aluminium tubes.
