Heat exchanger with coating turbulent flow device

The utility model discloses a heat exchanger with a coating turbulent flow device, which comprises a heat exchange tube, and the turbulent flow device is arranged in the heat exchange tube and used for adjusting the flow of fluid flowing through the heat exchange tube. A coating with corrosion resistance and hydrophobicity is additionally arranged on the surface of the turbulent flow device, and coating is conducted in one or more combined coating modes of dip coating, spraying, electroplating and brush type coating. Water is in full contact with the inner pipe wall of the heat exchange pipe through the turbulent flow effect of the turbulent flow device, the turbulent flow device is prevented from being corroded by CO2 or other impurities in the water through the anti-corrosion coating, so that the turbulent flow function is reduced or lost, and the heat exchanger has the advantages of being resistant to corrosion, high in heat exchange efficiency, capable of reducing energy consumption and long in service li
