The most notable improvement has resulted in a helical baffle as shown in Figure 2. Baffle enhancements have attempted to alleviate the problems associated with leakage and dead areas in the conventional segmental baffles.

Deficiencies of the segmented baffle include the potential for dead spots in the exchanger and excessive tube vibration. \"When none of the fluid condenses or evaporates, the unit is called as Heat Exchanger.\" In this only the sensible heat transfers from the one fluid to another. The one, which flows through the shell side, is called as shell side fluid
