Coolant lines
The coolant lines are a major part of the cooling system. They have a great
influence on the operational safety and pressure drop of the system. The
lines can be made up as hoses or pipes.
The continuous bending strain of the coolant lines always have to be taken
into account when they are sized and selected.
Further optional components
● Distributions
● Coolant temperature controller
● Flow indicator
A message is output when the flow drops below a minimum flow quanti‐
ty.
● Level monitor
Mainly minimum-maximum level monitors to check the coolant level in
the coolant container.
● Overflow valve
● Safety valve
Opens a connection between the coolant inlet and tank when a certain
pressure is reached
● Coolant filter (100 µm)
● Coolant heating
To provide coolant at a correct temperature, in particular for coolant
temperature control
● Choke and shut-off valves
Circuit types
The two possible ways of connecting hydraulic components (series/parallel
connection) show significant differences with respect to:
●
Pressure drop of the entire cooling system
● Capacity of the coolant pump
● Temperature level and controllability of the individual components that
are to be cooled
