9.7.7 Liquid cooling system
General information
Machines and systems can require liquid cooling for one or more drive com‐
ponents. If several liquid-cooled drive components exist, they are connected
to the heat removal device via a distribution unit.

Heat removal device The heat removal device dissipates the total heat that was fed into the liquid
into a superordinate coolant. It provides a temperature-controlled coolant and
thus maintains a required temperature level at the components that are to be
cooled.
There are three different types of heat removal devices. They are identified
by the type of the heat exchanger between the different media:
1.
Air-to liquid cooling unit
2. Liquid-to-liquid cooling unit
3. Cooling unit
A heat removal device includes a heat exchanger, a coolant pump and a
coolant container (see fig. 9-10 "Heat removal devices" on page 272 ).
