Twisted Tube Heat Exchanger is to strengthen the turbulence of the flowing gas/fluid, so that the gas and the tube wall contact thoroughly. In addition to enhancing heat transfer, the twisted tube heat exchanger also has the advantages of reducing scaling, self-supporting between tube bundles, no baffle plate elements and so on.
With that being said, novel Twisted Tube Heat Exchanger is much more efficient than conventional tubular heat exchanger, or Shell And Tube Heat Exchanger. Twisted tube heat exchangers are also used in applications where the fluids are corrosive or contain particulates, as they are better able to handle these conditions than other types of shell and tube heat exchangers or Air Heat Exchanger.
Twisted tube heat exchangers are constructed from a series of twisted tubes arranged around a central tube. The tubes are twisted in such a way that the fluid will change direction multiple times as it passes through the exchanger. This increases the turbulence of the fluid and creates a larger surface area for the heat exchange, which increases the efficiency of the exchanger.
The shell is usually made from a thick metal such as carbon steel, which increases the durability of the exchanger.
