process principle: working fluid is flowing inside of the coils,which is enwrapped by spray water on the outside.the heat of water is transferred by coil and become the saturated vapor when meet the water and air.the heat is exhausted out of the tower by the fan;tater is collected back to the bottom tank.the spray water is cooled down via PVC radiation fin in the process of circulation,and flows in the same direction with the fresh wind.the coil mainly takes sensible heat travel tylse.and thiswill apply especially to dealing with high temperature fluid. product characteristics: 1.easy to maintain the huge inside spare space is convenient for people to access to maintain the cooling tower. 2.avoiding scaling better water coverage around the tubes is due to air and spray water flowing in smooth,parallel,downward path over the coil,promoting dry spots since the water is not stripped from the underside of the tubes by the airflow. Mixed flow series principle of operation: 1.the cooled water increases the temperature differential between the water and the warm process fluid,which results in a reduced coil size,fewer coil connections,and reduced weights.this feature further reduces the tendency to form scale on the coil since cooler water offers higher solubility for scale producing compounds. 2.parallel air and water paths minimize scale-producing dry spots that may be found on the bottom of tubes in conventional units. 3.the recirculating spray water falls from the coil to a wet deck surface section where it is cooled by asecond fresh air stream using both evaporative and sensible heat transfer proeesses. 4.water is pumped over the evaporative coil at a 6.5L/S of coil face area to ensure continuous flooding of the primary heat transfer surface which enhances heat transfer efficiency and minimizes fouling and scale formation. 5.the coils section rejects heat through the fresh air evaporativing,on the other side is through the sensible heat effect of pre-cooled circulating spray water.reducing the coils evaporative cooling effect is helpful to reduce the possibility of the coils surface scaling.
