316L Spiral wound tube heat exchanger
The coil wound heat exchanger design entails winding many small diameter tubes in a helical geometry around a central core tube, or mandrel. The tubes are arranged in multiple layers within a cylindrical shell. The arrangement is quite flexible, allowing multiple streams to be accommodated in a single heat exchanger in more complex configurations. CWHEs are used in multiple industries including the cryogenic industry, for the production of Liquefied natural gas (LNG), Liquid Nitrogen, Liquid Oxygen, and Liquid Argon.316L Spiral wound tube heat exchanger
The consistent length of the heat exchanging cylinders and the precise core and interlayer spacing make the medium have a strong turbulent effect when flowing through the shell and tube, which greatly improves the efficiency of heat transfer. The heat transfer ability is 3-7 times greater than the conventional heat exchanger, and the maximum heat transfer coefficient can reach 14000W/m2℃. Additionally, the scaling tendency is lower and has a lower probability of impurity deposition. The spiral wound cylindrical structure completely eliminates the pull-off force between the heat transfer tubes and the tube plates, greatly extending the product’s lifespan. For an equivalent heat exchange, its around 1/10 of the size of a conventional one, saving valuable space.
