Characteristic data of water-cooled units, types J, K and L

The tables listed below give the rated water flow volume in l/min and
the pressure difference (in Pa) across the heat sink at rated flow
volume.
The water-cooled units have a lower power loss (i.e. a higher efficiency)
than the air-cooled units. The power loss is given in table 11-8.
MASTERDRIVES with water-cooling have the same power rating as
the air-cooled units. Since the thermal resistance of the heat sinks for
the IGBT is distinctly better than that attainable with air-cooling, the
modules are operated with a junction temperature that is 20 K lower.
The result of this is that the module losses are about 5 % lower.
This effect also gives the modules a good life expectancy.
Many units are also equipped with small built-in fans. The lower power
losses of these can also be taken into account.
In the tables below, the data for new units or more exact data are
printed in bold type.

* The sound level was determined under the following boundary conditions:
Distance to the unit 1 m, height above floor level 1 m, distance to the next reflecting
wall 4 m, room height 6m.
The chassis were installed in Siemens 8MC cabinets without any special
soundproofing measures.
