CE - ACF Door Heat Exchanger - Sub-Project (2026-02-05)

Why It Matters

These initiatives accelerate open‑source cooling standards, enabling faster, more efficient AI data‑center deployments and creating new market opportunities for participating vendors.

Key Takeaways

• OCP aims for gigawatt‑scale AI deployment using liquid cooling.
• Door heat exchanger specification workstream launched; community contributions invited.
• Barcelona summit abstracts due Feb 9; sponsorships available for networking event.
• Flow‑control white paper progresses; two‑phase cycle and telemetry sections assigned.
• Aluminum heat exchanger corrosion testing starts at OVH data center next month.

Summary

The monthly OCP community call focused on the ACF Door Heat Exchanger sub‑project and broader OCP initiatives. Participants reviewed upcoming events, including the Barcelona summit with an abstract deadline of February 9, and highlighted sponsorship opportunities for the high‑attendance liquid‑cooling networking event. Key updates covered the launch of a new door‑heat‑exchanger specification workstream, now hosted on GitHub and open to industry contributors, as well as progress on the flow‑control white paper, where two‑phase cycle and advanced telemetry sections have been assigned and are nearing completion. The call also detailed ongoing sidecar liquid‑cooling efforts, fan performance studies, and control‑strategy discussions, emphasizing collaborative data collection and simulation. Finally, a corrosion‑testing bench for aluminum heat exchangers was built and will be deployed at OVH’s data center to validate long‑term durability under real‑world conditions. Overall, the meeting underscored OCP’s push toward gigawatt‑scale AI deployments, liquid‑cooling innovations, and community‑driven standards that aim to accelerate adoption across the data‑center ecosystem.
