Advantages and product features of Sinlion aluminum alloy evaporative cooling and closed Tower: 1、 With superior processing performance, the special seamless heat exchange coil made of self extrusion is used for one-time bending forming, and the number of welding joints for continuous bend is small. The material is special antirust aluminum alloy, and its pressure blasting test and corrosion salt spray test have passed the test of national level testing agency and issued a test report. 2、 It is not easy to scale. Due to the large thermal expansion coefficient of aluminum alloy, the surface of the pipe is smooth. The scale on the surface of the coil will fall off and not harden due to thermal expansion and cold contraction. 3、 The aluminum alloy pipe wall is clean and free of impurities. 4、 The thermal conductivity of aluminum alloy is large. As a result, the heat transfer effect of aluminum alloy evaporative cooling and closed tower is much higher than that of carbon steel and stainless steel, and the cost performance of aluminum alloy tube used in closed tower with the requirement of water quality in the tube is higher. 5、 As the aluminum alloy raw material adopts the bar with high cleanliness, the extruded aluminum tube wall has no porosity and impurities, which greatly improves the service life of the aluminum alloy tube. As the early used Sinlion aluminum alloy evaporation cooling and closed tower in China, the core of the heat exchange coil is guaranteed for three years. 6、 The weight of aluminum alloy evaporation cooling is about 60% of carbon steel evaporation cooling. Because the evaporation cooling is placed on the roof in most cases, the weight is greatly reduced and the installation cost is saved compared with carbon steel evaporation cooling. 7、 According to the different use environment of customers, we will recommend carbon steel seamless high-frequency welded pipe as a whole hot-dip galvanized or 304 stainless steel for coil material selection to meet the needs of different occasions. Select a certain brand of material configuration, and select high-end aluminum zinc plating steel plate for the external box of the equipment, which has super corrosion resistance, and extends the service life of evaporative cooling and closed tower.
