Integrated Water-cooled Heat Sink

The devices 0362111OF and 0362111RF provide an integrated water-cooled heat sink
for cooling.
The heat sink is an aluminum body with copper tubes (stainless steel tubes are avail‐
able on request).
CAUTION
Risks when handling cooling liquids
Cooling liquids can cause damage to health and environment: Avoid skin and eye
contact. Dispose cooling liquids in an environmentally acceptable way according to
the local regulations.
Cooling liquids can heat up to a temperature of 80 °C and might be under high
pressure: Use collection containers for liquid leakage.
Pay attention to the following notes about liquid coolants:
▶ The inlet temperature of the coolant must not exceed 40 °C.
▶ The coolant must be based on water and it must contain corrosion inhibitor.
▶ Anti-fungal agents can prevent clogging of the cooling pipes.
▶ The coolant must be cleaned.
▶ No solid objects must be carried along.
▶ The system monitoring should check the following parameters:
─ temperature
─ maximum pressure
─ pressure loss (system leakage)
─ flow rate
▶ The coolant must be chemically neutral.
▶ The operating pressure must not exceed 6 bar.
▶ The flow rate is specified in the technical data of your device.
▶ Bedewing at the heat sink and the connected cooling pipes must be prevented.
(Bedewing is caused especially, when the coolant temperature is low and high
humidity in connection with high temperatures is present.)
Connection of the cooling unit
DANGER
High voltages in connection with cooling water
Before you carry out any works at the cooling circuit, you must switch all electric
equipment located in the danger area into the de-energized state (e.g. switch
cabinet). Wait until the respective discharge times of the electric equipment are
passed.
Check that the cooling system is watertight before you connect any electric equip‐
ment located in the danger area (e.g. switch cabinet) to the mains supply.
There are 2 tubes with a diameter of 10 mm each at the bottom side of the device.
These tubes are to be connected to a cooling unit for heat dissipation. The form of
connection to the cooling unit depends on the conditions in the machine.
