Parker Launches New Configuration Two-Phase Evaporative System, to Retrofit Legacy Cooling Systems in the Nacelle

As a follow-on to last year’s announcement by Parker Hannifin of a “rack-ready” evaporative cooling system for wind turbine systems, the company has developed a stand-alone configuration of the system as a drop-in replacement for easy retrofit of existing wind turbine cooling systems (traditionally air- or water-based). The system is 50% lighter and more compact than legacy air and water cooling systems, and provides a convenient way to “upgrade” to a more efficient cooling system, delivering up to 40% increase in power throughput and, in many cases, enabling an increase in electronics density of 2X or more, in the same space.

About the Technology

Two-phase Evaporative Cooling is Parker’s patented technology and the basis for all its Precision Cooling Systems. The process continuously cycles a refrigerant within a sealed, closed-loop system to cool a wide variety of electronics. The system includes a small pump to deliver a just enough coolant to the evaporator (usually cold plates) to optimize the heat from the particular device. The vaporized content is then pumped to the system’s heat exchanger, where it rejects the heat to the ambient and then condenses back into a liquid, completing and repeating the cycle.

Parker Wind Turbine Cooling System’s Application and Benefit:

Parker’s precision cooling systems, based on its patented two–phase evaporative thermal technology, are 50% lighter/smaller than traditional air/water cooled systems, and fit easily into the nacelle, while enabling up to 40% higher throughput from system electronics, and up to twice the density in the same space, at reduced cost, with inherent safety and simplified maintenance, due to their modular and scalable design. All critical wind turbine systems can benefit from these integrated cooling systems, including the inverter, reactor, and generator as well as other electronics either in the nacelle or in-field containers.

Available in two convenient configurations:
• Rack-Ready Integrated Design for each Wind Turbine System (introduced at AWEA Windpower 2011)

• Stand-Alone Cooling Kit (in scalable models), servicing multiple systems with localized cold plate kits – new for AWEA 2012! The high-resolution photo is attached for your use.
