Location: SJCC – Concourse Level – 210AE

Topic: CDU Test Requirements and Methodology

Liquid cooling technology is becoming more ubiquitous due to increasing power and densities of processors and other IT components. Air-cooling solutions cannot always address the thermal challenges of high-performance computing systems with high thermal design power processors. The Coolant Distribution Unit (CDU) is a key ingredient of liquid cooling flow network, which circulates coolant fluid between the heat exchanger and IT equipment. CDU design, manufacturing and qualification requires special consideration on material selection and evaluation to comply with the application requirements. All wetted materials must be compatible with the fluid to prevent corrosion and contamination. The CDU has telemetry and control devices to monitor and maintain coolant circulation at the required pressure, temperature, and flow rate. This presentation provides CDU test requirements and methodologies addressing cooling performance rating, quality control, and recommendations on basic qualification methods.

Topic: The Trade-offs Between Single-phase and Two-phase DLC

With the growth of AI, liquid cooling of IT equipment is no longer optional. Power consumption and heat dissipation have dramatically increased. Liquid cooling is now required to manage heat loads of AI semiconductors with historically high heat fluxes and AI servers with increasing rack densities.

There are two core approaches to liquid cooling: single-phase using water or a water-glycol mixture as a coolant and two-phase using refrigerants. In single-phase cooling, the coolant remains in the liquid state, whereas in two-phase cooling, the refrigerant changes between liquid and gas phases.

In this forum, we will provide a technical assessment of single-phase and two-phase direct-to-chip liquid cooling (DLC) technologies, focusing on system design and operational differences. These differences help explain why single-phase DLC, today, is a mature technology seeing mainstream adoption. In contrast, two-phase DLC is earlier in the technology adoption cycle and still faces technical and operational hurdles.
