Addressing the global demands for data storage presents significant financial, energy, and environmental challenges. However, a pioneering material has the potential to enhance cooling mechanisms in data centers, while simultaneously improving energy efficiency in both domestic and commercial electronic devices.
Traditionally, large and energy-consuming cooling systems are employed to regulate the temperature of the hardware that stores our data. These solutions contribute to approximately 40 percent of overall data center energy consumption, amounting to around 8 terawatt-hours annually.
Researchers from the University of Texas at Austin and Sichuan University in China project that their innovative organic thermal interface material (TIM) could reduce this figure by approximately 13 percent.
This TIM remarkably accelerates the dissipation of heat from active electronic components, efficiently transmitting it to a heatsink for dispersal via air or water cooling systems. This advancement effectively lessens the reliance on active cooling technologies such as fans and liquid cooling systems.
“The energy consumption associated with cooling systems for data-intensive centers and comparable large electronic infrastructures is escalating dramatically,” remarks materials scientist Guihua Yu from the University of Texas at Austin.
“This trend shows no signs of abating, which necessitates the development of innovative, efficient, and sustainable cooling solutions for devices operating at kilowatt scales and beyond.”
The TIM in question is a carefully crafted colloidal mixture of the liquid metal galinstan and aluminum nitride particles, designed to create a gradient interface that promotes seamless heat transfer.
In controlled laboratory tests, this TIM successfully doubled the rate of heat transfer per square centimeter from electronic components, outperforming leading thermal pastes and simultaneously lowering the components’ operational temperatures.
Using a standard cooling pump for overheating prevention, the TIM achieved a remarkable reduction of 65 percent in pump energy consumption. Although this trial was on a smaller scale, it underscores the material’s exceptional thermal transfer capabilities.
“This advancement brings us closer to realizing the ideal performance predicted by theoretical models, paving the way for more sustainable cooling methods for high-power electronics,” comments Kai Wu from Sichuan University.
The subsequent phase involves implementing the material in larger systems and diverse environments, with researchers actively collaborating with data center providers to expedite this process.
Projections suggest that by 2028, electricity consumption in data centers may double compared to 2023, primarily driven by the escalating needs of artificial intelligence models. This trend presents a considerable energy challenge, one that scientists are diligently working to mitigate.
“Our material has the potential to enable sustainable cooling for energy-intensive applications, ranging from data centers to aerospace, laying the groundwork for more efficient and environmentally friendly technologies,” asserts Wu.
The findings of this research have been published in Nature Nanotechnology.
