摘　　要：针对过冷水动态制冰过程中过冷却器内易发生冰堵现象,采用纳米氟碳材料对过冷却器表面进行处理,并对纳米氟碳涂层过冷却器进行动态制冰试验研究及性能分析。研究结果表明:水在纳米氟碳涂层表面的接触角可高达163.01°,可有效抑制过冷却器结冰;对比无涂层过冷却器,在过冷水流速为1.95 m/s时,纳米氟碳涂层过冷却器出口过冷度降低0.75℃,持续制冰时间增加约50 s。In view of the phenomenon that ice blocking is easy to occur in the subcooler during the dynamic ice-making process of subcooled water, the surface of the subcooler is treated with nano-fluorocarbon materials, and the dynamic ice-making experiment and performance analysis of the nano-fluorocarbon coated subcooler are carried out. The study results show that the contact angle of water on the surface of nano-fluorocarbon coating can be as high as 163.01 °, which can effectively inhibit the icing of subcooler. When the flow speed of subcooled water is 1.95 m/s, compared with the subcooler without coating, the subcooling degree at the outlet of the nano-fluorocarbon coated subcooler is decreased by 0.75 ℃, and the ice making duration is increased by 50 s.
