General information

Cold plate cooling is a cooling method that can be used for SINAMICS S120 power units in
booksize format. The flat aluminum cold plate (cold plate), which is located on the rear of the
device, acts as a thermal interface in cold plate cooling.
The cold plate cooling is especially suitable for the following machine concepts:
● Plants and systems with high degree of pollution in the vicinity of the machine (e.g. in the
● Plants and systems where liquid cooling is already being used in the process.
There are two ways of configuring this type of cooling:
1. Cold plate cooling with an external air heat sink
2. Cold plate cooling with an external liquid heat sink

textiles or timber industry).
– Reducing cabinet-internal thermal losses facilitates cooling within a sealed cabinet
(IP54).
– The existing cooling circuit can be used to externally cool the power components with
cold plate.
The components of the drive line-up are typically all screwed on to the cooling fins of an
air heat sink located outside the control cabinet.
