4.1.5.2 Demands on the cooler
Coolers, which can be operated with different coolants (air, water, oil, etc.),
can dissipate the power loss of the controller.
In addition to the features required by the user, the following features are
important for safe operation:
- Good thermal connection with the cooler
- The contact surface between cooler and controller must be at least as
large as the cold plate of the controller.
- Smooth contact surface: approx. 0.05 mm
- Connect cooler and cold plate by means of the provided screws.
- For further information see chapter 4.1.5.4 ff.
- Observe the thermal resistance R
thmin heat sink
(transition cooler - coolant)
according to the table. The values are valid for
- the operation of controllers under rated conditions (see chapter 3.4),
- a max. temperature of the cold plate of 75 EC, measuring point: see
FIG 4-11, FIG 4-13, FIG 4-14.
