Parker’s Precision-Cooled Rack Solution features patented two-phase evaporative cooling for things that must stay cool in turbine nacelles.
The flexibility of Parker’s technology and its use in racks, cabinets, and containers has been implemented in many other industrial markets where it has been easily configured to cool a variety of applications such as power electronics, motors, transformers, and batteries. Dual-phase liquid cooling continuously cycles a refrigerant within a sealed, closed loop to cool a wide range of devices. The cooling 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 warm device. 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.
The cooling rack works well in wind turbines where the size and weight in the nacelle continues to grow with total capacity. In addition, the Parker precision-cooled rack is the only product available today offering the potential to double 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, while reducing overall maintenance costs.
