4.3.1 Functional principle
In the cooling circuit the coolant (water or wator/glycol) is driven by the pump to the device that is to be
cooled and back via the return flow. The heat is transferred to the cooling water through a plate heat
exchanger following the principle of opposing flows. The heat is then dumped from the unit by the cooling
water.
The coolant temperature is controlled by an electric thermostat, whereas coolant throughput is controlled by
a flow control device. Both indications are made potential-free and must be integrated into the safety circuit
of the device to be cooled.
