A new type of baffle, called the helical baffle, provides further improvement. This use of continuous helical baffles reduces shell-side pressure drop and helps improve heat transfer performance of shell and tube heat exchanger. Properly designed continuous helical baffles can reduce fouling in the shell side and prevent the flow-induced vibration as well. The use of continuous helical baffles results in nearly 10% increase in heat transfer coefficient compared with that of conventional segmental baffles for the same shell-side pressure drop. Helical baffles are employed increasingly in shell-and-tube heat exchangers (helix changers) for their significant advantages in reducing pressure drop, vibration, and fouling while maintaining a higher heat transfer performance.
