Parker Hannifin Corporation, a developer of motion and control technologies, has released new two-phase evaporative liquid cooling systems for renewable energy power conversion systems.
“The Parker system’s inherent cooling efficiency benefits can result total system cost reductions of up to 15 percent, and/or enable up to a 33 percent increase in converter rated capacity using the same architecture,” the company said.
Available in capacities of 8KW, 18kW, 50kW, and 100kW, the new evaporative liquid cooling system “uses a refrigerant to circulate within a sealed, closed-loop system to cool a wide range of wind turbine systems, including the generator, reactor, transformer and the converter,” and “a small pump to deliver just enough coolant to the evaporator—usually a series sealed cold plates optimized to acquire the heat from the device. In so doing, the coolant begins to vaporize maintaining a cool uniform temperature on the surface of the device being cooled. In its evaporated state, the coolant then flows through a heat exchanger where it rejects the heat to the ambient and condenses back into a liquid, completing the cycle.”
A 50kW configuration of the new evaporative cooling system will be displayed at the upcoming Power Gen/Renewable Energy World Europe conference in Vienna, Austria in early June.
