Liquid Cooling System Requirements
Proper cooling is critical to liquid-cooled drive operation and reliability. This section provides an overview of the types of drive cooling loops, drive coolant requirements, and cooling loop connections for the
PowerFlex®
755TR liquid-cooled drive power structure.Liquid-to-Liquid Heat Exchanger Cooling Loop
The liquid-to-liquid heat exchanger uses a heat transfer plate to transfer heat from one liquid to another. This method requires a stable water supply from the user.
