Water cooling unit (WCU)
The closed-loop water-cooling system transfers the heat losses of the
main power electronics components of the drive (eg, rectifier bridges,
inverter phase modules, DC-link capacitors) to the exterior.
Redundant pumps circulate the coolant through the feeding pipes to the
power electronics components and transfer the heat losses through the
return pipes and the water-to-water heat exchanger.
The water cooling units are accessible for maintenance even when the
drive is in operation.
