Liquid-liquid heat exchanger
In the liquid-liquid heat exchanger, two liquids are hydraulically separated
and brought to the best possible thermal contact. The power dissipation ab‐
sorbed by the coolant is thereby dissipated to the higher-level cooling circuit
(utilities).
These cooling units are suited for the coolants specified in this documenta‐
tion. Depending on the type of material, you can use fresh water, river water,
industrial water, seawater or brackish water as utilities.
