Figure 2-1 Example: cabinet setup with powers ections, cold plate, and external air heat sink
In the cabinet, a fan is installed above the power sections.
To optimize usage of the external air heat sink, it is best to arrange the components in such
a way that the heat is dissipated equally over the surface of the external heat sink. This
means that, if possible, a large power section should be situated next to a smaller one. The
current carrying capacity of the DC link busbars must be taken into account here.
