3.54. Heat Exchanger with expansion box in the casing

To include the expansion box in heat exchanger model, select an appropriate checkmark in the "Expansion box” tab (Fig. 1). In the presence of expansion box on the expander, its parameters are set similarly to "Heat Exchanger with expansion box on the casing".

When calculating the heat exchanger, the flexibility of the expansion box is taken into account. If the expansion box is made with bellowed sides, use this option (Fig. 2).

Do not use the "Expansion box" option to define the distribution manifold (without cutting the casing section under it) - for this, use the Cylindrical jacket component.
