Heat Exhcnager Baffles - China

Heat Exchanger Baffles are plates used to change the direction of fluid flow.

They are commonly used in shell-and-tube heat exchangers to design shell-side media flow paths.

The number of baffles is determined by the nature and flow of the media and the size of the heat exchanger.

The baffle is placed on the shell side, which improves heat transfer and supports the tube bundle.

The baffle has two kinds of bows and discs—circular rings.

The bow baffles have three kinds of bows: double bows and three bows.

Heat Exchanger Baffles serve three functions:

1) support the tube;

2) maintain the tube spacing;

3) direct the flow of fluid in the desired pattern through the shell side.

A segment, called the baffle cut, is cut away to permit the fluid to flow parallel to the tube axis as it flows from one baffle space to another.

Segmental cuts with a segment height of approximately 25% of the shell diameter are usually the best.

Baffle cuts larger or smaller than the optimum typically result in poorly distributed shell side flow with large eddies, dead zones behind the baffles, and pressure drops higher than expected.

The spacing between segmental baffles is called the baffle pitch.

The baffle pitch and the baffle cut determine the cross-flow velocity, and hence the rate of heat transfer and the pressure drop.

The baffle pitch and baffle cut are selected during the heat exchanger design to yield the highest fluid velocity and heat transfer rate while respecting the allowable pressure drop.

The orientation of the baffle cut is important for heat exchangers installed horizontally.

When the shell side heat transfer is sensible heating or cooling with no phase change, the baffle cut should be horizontal.

This causes the fluid to follow an up-and-down path and prevents stratification, with warmer fluid at the top of the shell and cooler fluid at the bottom of the shell.

For shell-side condensation, the baffle cut for segmental baffles is vertical to allow the condensate to flow towards the outlet without significant liquid holdup by the baffle.

Depending on the service, the baffle cut for shell-side boiling can be vertical or horizontal.

Other types of baffles are sometimes used, such as double segmental, triple segmental, helical baffle, EM baffle, and ROD baffle.

The majority of these baffles are intended to provide fluid flow paths other than cross flow.

These baffle types are typically used for unusual design conditions.

Longitudinal baffles are sometimes provided to divide the shell, creating multiple passes on the shell side.

When several shell side passes allow for a severe temperature cross, this type of heat exchanger can be useful in heat recovery applications.
