Cooling concept

SINAMICS S120 – Cooling concept

The devices are cooled in 3 different ways, depending on the power rating and the particular type:

In this standard solution, the power loss from the electronics and power units of the drive components is removed by natural cooling or by a forced ventilation system and routed to the interior of the control cabinet.

A liquid cooling system on Chassis and Cabinet Modules allows significantly more efficient heat dissipation such that an air conditioning system is not required. With a low energy input for liquid cooling, significant energy savings can be achieved during operation. Further, there is the possibility of heat recovery. Compared to air cooling, the benefits provided by liquid cooling with a closed cooling circuit at high power ratings include a small footprint, reduced weight and low-noise converter operation. The maintenance expenditure required for the units is reduced through omission of filter mats. The coolant must be provided with the corresponding additives. It is thus advantageous to use the system especially in small and badly ventilated rooms and under harsh environment conditions prevailing, for example, on ships and in industrial environments.

A water cooling system for common circuits allows to use the water provided in the factory. This provides a common cooling circuit for the system, motor and converter. Only reduced requirements are placed regarding the water quality. No additives need to be added to the water circuit, which allows convenient and environment-friendly commissioning and maintenance. Further, the converter is resistent to oxygen entering the cooling water. The benefits provided by liquid cooling, for example, significant energy savings and efficient heat recovery, are also ensured for water cooling.
