Shell has launched a new direct liquid cooling (DLC) fluid called DLC Fluid S3, specifically designed to meet the increasing thermal demands of artificial intelligence (AI) and high-performance computing (HPC) workloads. This innovative coolant aims to enhance efficiency, reliability, and sustainability within modern data centers.
DLC Fluid S3 is based on a propylene glycol formulation that provides superior thermal conductivity while being compatible with contemporary cooling hardware. It complements Shell’s existing immersion cooling products by targeting the cooling of critical components, like CPUs and GPUs, directly at their heat sources.
With higher server densities and intensive compute loads, traditional air-based cooling systems often fall short. Shell’s DLC technology allows for direct heat removal from high-load chips, which can significantly lessen the dependence on mechanical air conditioning systems. According to Shell, the new fluid can improve power usage effectiveness (PUE) by up to 27% compared to standard air cooling setups.
The fluid adheres to Open Compute Project PG25 coolant specifications, which are recognized industry standards that ensure compatibility, material safety, and performance. Notably, the DLC method prevents the coolant from making direct contact with semiconductor surfaces, thus preserving hardware warranties and maintaining overall system integrity.
Enhanced Longevity and Safety Features
Shell has incorporated several technical attributes aimed at prolonging the durability and safety of data center operations. The DLC Fluid S3 offers long-term corrosion protection across multiple metals, including copper, brass, aluminum, and steel, which are commonly found in heat sinks and piping. It avoids problematic additives, ensuring compatibility with rubber seals and polymer components.
The expected operational lifespan of the fluid exceeds six years, which is more than double that of typical inorganic acid-based coolants. It also features freeze protection down to -10 degrees Celsius, utilizes a fluorescent green dye for easy leak detection, and boasts strong thermal transfer capabilities, particularly in systems employing copper-based heat sinks.
Aysun Akik, Vice President of New Business Development and Global Key Accounts at Shell Lubricants, emphasized the product’s strategic importance for the future of digital infrastructure. She pointed out that Shell is now equipped to provide both direct-to-chip and immersion cooling solutions, giving data center designers flexibility to meet diverse thermal challenges.
Additionally, Shell’s extensive global infrastructure, featuring five technology development hubs and a robust international supply chain, positions the company to deliver innovative cooling technologies that align with the sustainability and efficiency objectives of its enterprise clients.
The introduction of DLC Fluid S3 comes during a period when many data center operators are reassessing their cooling strategies. As the demand for computing power continues to surge, particularly driven by advancements in generative AI and machine learning, effective thermal management is becoming crucial for operational performance and environmental sustainability. Shell’s new fluid indicates a commitment to leading the shift toward more efficient cooling solutions in the data center sector.
