Cargill says it has developed the first plant-based dielectric immersion cooling fluid. Intended for use in data centers, cryptocurrency mining and other applications, the heat transfer fluid allows for a sustainable and efficient way to cool electronic systems.
NatureCool 2000 is made from more than 90 percent vegetable oil combined with additives. It allows for more than 1,000 times more cooling capacity and up to 60 percent less energy usage compared to conventional air cooling, according to Cargill.
The fluid is CO2 neutral with a global warming potential of zero, helping make applications adopting the fluid more sustainable. According to Cargill, it has a 10 percent higher heat capacity than typical synthetic immersion cooling fluids and provides a high level of fire safety with a flash point of 617°F (325°C). Unlike synthetic fluids, NatureCool does not self-ignite and flames out after the heat source is removed.
“Immersion cooling…allows for more efficient, higher performing systems that also help make the IT industry more sustainable,” said Kurtis Miller, managing director of Cargill’s Bioindustrial business. “In just the last 10 years, data center power usage has increased from several hundred kilowatts to several hundred megawatts, an over 1,000 times increase. As chip density continues to rise and the amount of data generated seems endless, we need to find more efficient and sustainable ways to operate these complex systems.”
