Industrial cooling tower 
 Industrial cooling tower cooling hot water by rotating sprinkler systems average spread in the film, and then from the top of the axial-flow fan dry air at the bottom belt, so that the hot water in contact with air convection arising from volatile the fall in temperature. The collection of the cooling water by the end of the basin by the pump is running to the heat source for recycling. 
 Cooling tower product description 
 Cooling tower and technical data 
 First, the product classification: 
 Cooling towers designed three models, respectively, as the standard type, high temperature, ultra-low noise type. Each model, respectively dozens of specifications to meet the requirements of different water tower water and the use of the different purposes of customers. 
 Second, the product design and performance parameters: 
 According to the provisions of GB7190.1-1997: standard type cooling towers of the design wet bulb temperature of 28 ° C, in general, the design wet bulb temperature of 27 ℃ water cooling towers in a well ventilated, no other special environment of northern climate normal use, but after running effect of the cooling towers for many years to collect the feedback information indicates that, in some south regions of hot and humid climatic conditions or poor ventilation, easy to form a high temperature environment and climate of buildings, wet bulb 28 ° C design cooling towers to show its excellent heat dissipation and extraordinary ability to respond to the project designers, installers and users confidence in the peace of mind. 
 Cooling towers is constantly sum up experience and improve the high quality of the water tower technology, decided to adopt a temperature 28 ° C for the design conditions to ensure that towers. 
 Standard, high temperature, ultra-low noise design conditions: 
 The inlet water temperature 37 ℃, out tower water temperature 32 ° C 
 Wet bulb temperature is 28 ℃ dry bulb temperature of 31.8 ° C 
 Third, the cooling tower performance is introduced: 
 1, the overall effect: 
 The cooling tower theory is of a very complex system of highly experimental discipline. Scientific and technical personnel of the company in the thermal test trials by the cooling tower for many years on the basis of comprehensive and integrated treatment of the test data, based on computing the volumetric mass transfer coefficient (35 × 20-75 °) trapezoidal wave of water filler derived Βxv , select the best air-water ratio, the best section of water load, the height range of the sectional gas load and high packing efficiency, in order to determine the filler volume, shape and structure to design the tower of the fluid dynamics point of view, according to a test to estimate the ventilation resistance , optimizing selection of the fan characteristics curve and test data, to meet air flow requirements and to achieve the noise standard fan and the matching of the motor, so the effect of cold efficiency, energy consumption, noise, appearance to achieve an optimized system. 
 2, structural features: 
 Packing: standard, high temperature, ultra-low noise cooling tower fill by the modified PVC (polyvinyl chloride) plain film by hot rolling molding processing Packing in the role will need to cool the hot water spurting into droplets and form a water film to increase the contact area and contact time of water and air, that is, increase the intensity of heat exchange of water and air. Water cooling process, tricking filler, water and air heat exchange and mass transfer in the water spray filler. The cooling effect of the cooling tower depends largely on the Packing in the heat exchange performance. Good performance tricking filler has a high heat capacity, the structure and composition of the filler into the board (35 × 20-75 °) trapezoidal wave tricking filler design advantages: 
 A cooling area of ??the growth factor. 
 2, the performance of flow distribution in the surface of the plate. 
 3, water and air flow cross-board disturbance. 
 These advantages make the cooling tower to obtain a higher cooling performance. 
 Fan performance: comparative test, the cooling tower fan selection of low-speed space warp forward aluminum cooling tower fan. Product of the fan completely under various conditions to ensure the cooling tower air flow, pressure, noise and drift water level and operational performance to meet the technical requirements, its performance characteristics are: 
 A fan blade with the production of aluminum alloy plates, machine number> 12 # fan angle adjustable, seasonal changes, the replacement of the blade angle to adjust the air volume, air pressure, in order to improve the device efficiency to save energy. 
 Fan with a large chord length, spatial distortions, forward curved blade, low-speed drive, to achieve a uniform air speed, air volume, high efficiency, low noise, low power consumption province. 
 3, leaves were balanced than testing balanced accuracy of ISO-2.5. 
 C, with water part of the performance: 
 The role of the water distribution system is hot water splashed on the whole tricking filler. With the performance advantages and disadvantages of water distribution, will directly affect the air distribution uniformity and packing the ability to play a cooling effect. The cooling tower uses a rotating tube with water, the reaction force to promote the use of cloth on the water in the shower jets orifice jet water distribution mains rotation, tricking filler surface rotation and uniform water distribution. The advantages of using this water distribution mode is: 
 1, water pressure is low, energy-saving. 
 2, the water distribution uniformity performance. 
 3, water pipes equipped with flap, with some promoting uniform water distribution and elimination of the drift of the role of water. Use copper alloy production of turned parts of the water distribution, compact structure, high strength, corrosion, after the practical test, the failure of this water distribution, and stable performance. 
 D, the tower structure and performance: 
 Water the Tata body using high-quality glass fiber reinforced plastic material, the surface gel coat with the manufacture of the imported raw materials, color species containing UVS optical stabilizer so that the bright color tones evenly, not faded, aging resistance, lasting even worse shiny all steel were hot dip galvanized. a large number of injection molding components, corrosion resistance, high strength, light weight, versatility, easy assembly. 
 The design of the cooling towers to control the drift of water, leaching losses of less than 0.001%, and its measures: 
 Maximize the use of low-speed fans, to avoid excessive water mist into the air. 
 Cloth water pipes with compartment sleeves to collect spurting droplets. 
 3, the end of basin is greater than the design of the shell diameter, and with PVC into the wind, one hundred to prevent water spills tower. 
 Low noise, with noise control principle: 
 1, to reduce the noise of the sound source. Using fully enclosed self-cooled low-noise cooling tower motor, the motor waterproof performance, low noise, to meet the special requirements of the cooling tower operating conditions of motor. 
 2, cut off the noise propagation path. 
 3, the receiver of the protective measures. 
 Change the partition noise path such palliatives. Using a combination of both tackling the problem. The sides, into the wind network, the muffler is the use of sound reflection principle, to achieve sound insulation purposes. 
 Ultra-low noise cooling towers is very soft and flexible organic polymer materials, and silencer good effect, good water permeability, corrosion resistance and durability.
