Properties of the heat sink
AlMgSi 0.5 is recommended as the heat sink material.
The roughness of the external heat sink surface should be at least Rz 16 and the contact
surface between the heat sink and cold plate should have an evenness of 0.2 mm
(applicable to a height of 450 mm and width of 300 mm).
Note
Machine manufacturers can adapt the heat sink version to their special requirements. The
specified rated data for
the Power Modules can only be achieved if the power losses can be
dissipated by the external heat sink under the specified general conditions.
Damage to the cold plate caused by incorrect mounting
The screw bolts can be damaged when mounting the cold plate.
• Do not damage the cold plate.
