Fig. 1. Distribution chamber
Air-cooled heat exchanger is created as a model component. This component cannot be joined to anything. No other components can be joined to it as well in the current program version. Air cooled exchanger consists of two identical distribution chambers (Fig. 2) and tube bundle (Fig. 3).

Fig. 3. Types of tube bundles
Upon pressing 
button, tube bundle parameters
can be defined, similar to Heat Exchanger with
stationary tube plates.
