Spiral Heat Insulation Reinforced Tube Heat Exchanger For different application fields and heat transfer characteristics of heat exchange media (such as single-phase convective heat transfer, condensation heat transfer, and boiling heat transfer), three-dimensional finned tubes, low-ribbed tubes, and T-shaped finned tubes are respectively adopted as reinforced tube types, with spiral baffles serving as the supporting structure for the reinforced tubes. This design achieves synergistic heat transfer enhancement between the spiral flow of fluid and the special structure of the reinforced tube surface, resulting in the development of a new type of shell-and-tube heat exchanger featuring a combination of spiral baffles and reinforced tubes

       Spiral baffle enhanced tube heat exchanger has the advantages of high heat transfer coefficient, low pressure drop, and stable performance, thus solving the problems of low heat transfer coefficient, high pressure drop, bulky volume, high material consumption, and high energy consumption in the application process of the smooth tube heat exchanger with bow-type baffles. Under the same heat exchange area of the base tube, the total heat transfer coefficient of the spiral baffle enhanced tube heat exchanger is more than 40% higher than that of the ordinary smooth tube heat exchanger with bow-type baffles, and the pressure drop increase is not obvious. This heat exchanger has been widely promoted and applied in large domestic chemical and petrochemical enterprises such as Sinopec and China National Coal Group, achieving energy-saving and economic benefits
