Parker Hannifin’s Precision Cooling Systems will be displaying a new two-phase evaporative cooling unit for use with solar inverters. Using modular cold plate technology, and a refrigerant based, closed loop cooling system, the Parker system is more efficient and allows for 30% greater module density in each inverter cabinet, than when using traditional thermal management systems (air/water). The unit will be on display at the upcoming SPI
Parker Precision Cooling Systems’ revolutionary new precision cooled rack, features an alternative 2-phase liquid cooling thermal system for cooling critical solar inverter systems, and is ideal for systems that need to enable higher density power and other electronics. The rack 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, which vaporizes and cools hot surfaces on contact and is 2-4X more efficient at drawing away heat than traditional water or air-cooled systems. Parker’s Precision-Cooled Rack and cooling unit configuration provides an efficient solution in a smaller, lighter footprint than racks using alternative thermal management.
The two-phase liquid cooling process 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 vaporized 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.
