Parker Precision Cooling Systems' revolutionary new precision cooled rack solution is an alternative drop-in thermal system for cooling critical wind turbine systems. The drop-in solution features Parker’s proven and patented two-phase evaporative cooling thermal technology, which employs non-corrosive, non-conductive fluid, in a closed loop system to as it vaporizes and cools hot surfaces on contact, through cold-plate modules.  Parker’s Precision-Cooled Solution can be used to cool critical wind turbine systems, including power conversion electronics, the generator and the gear box, and also provides an efficient solution in a smaller, lighter footprint than racks using alternative thermal management. Parker’s Precision-Cooled Rack Solution is an ideal product for wind turbines where the size and weight in the nacelle continues to grow with total capacity.  Click here for video. )

 The dual-phase liquid cooling vaporizing process continuously cycles the refrigerant fluid (R134a) within a sealed, closed-loop system to  cool a wide range of critical electronics.   The precision colled system uses a small pump to deliver just enough coolant to the evaporator - usually a series of one or more cold plates optimized to acquire the heat from the device(s).  In so doing, the coolant begins to vaporize maintaining a cool uniform temperature on the surface of the device.  The resulting two-phase coolant is then pumped to a heat exchanger where it rejects the heat to the ambient and condenses back into a liquid, completing the cycle.                                                             .                     

Benefits:

System level cost savings are realized due to the use of smaller, lighter-overall thermal systems that are easier to maintain and run at lower, more reliable temperatures.  In addition, the Parker precision-cooled rack is the only product available today that offers the potential to double and even triple the power density of key major subsystems such as the generator and power conversion system, and whose modular thermal management elements greatly simplify onsite maintenance when required, resuling in a reduction of overall maintenance costs and an increase in overall reliability.

The compact and light rack-ready solution leverage Parker’s long established and proprietary two-phase liquid cooling technology and rack systems, and offers a cost-effective alternative solution for applications in renewable energy markets, such as wind and solar.   For more information, please contact Parker’s Precision Cooling Systems group at www.parkerprecisioncooling.com.   Parker's Precision Cooling Systems group is part of Parker Hannifin’s long established portfolio of thermal management technologies and systems for key industrial applications, and is based in New Haven, Indiana.
