Wiwynn unveiled several new AI infrastructure technologies at the Open Compute Project Global Summit on October 12, 2026, including a diamond-based microchannel cooling concept, a 6-kilowatt double-sided cold plate and lighter liquid-cooling components. The company also detailed rack designs for NVIDIA Vera Rubin and AMD Helios platforms. The announcement describes technology demonstrations and development work, not a claim that all products are shipping commercially.

The most unusual research item is a cooling structure that uses diamond-based composite material instead of a conventional copper heat-transfer surface. Wiwynn says it is exploring direct diamond-to-silicon bonding with integrated microchannels, seeking to shorten the path heat travels from a processor into coolant. Diamond’s high thermal conductivity makes it attractive for concentrated heat sources, although manufacturing complexity, bonding reliability, cost and long-term serviceability will determine whether the concept is commercially practical.

Another demonstration is a double-sided cold plate rated for 6 kW of cooling capacity. Wiwynn says its cavity-PCBA design works with vertical power delivery and delivers more than 15% better thermal performance and up to 80% less power-delivery loss. Those figures are company-reported design comparisons; the announcement does not establish that every installed system would achieve the same results. Cooling capacity and processor electrical consumption are different measurements and should not be treated as interchangeable.

The company is also trying to reduce the physical weight of liquid-cooling hardware. Wiwynn says lighter cold plates, inner manifolds and tubing can cut cooling-component weight by at least 30%. Lower mass could ease transportation, installation and rack service, but operators must still evaluate vibration, mechanical durability, leakage protection and compatibility with existing coolant-distribution systems.

With Corintis, Wiwynn plans to show topology-optimized microchannel cold plates tailored to a chip’s heat map. Instead of treating the entire processor package as one uniform thermal load, such designs can concentrate cooling performance where heat flux is greatest. The engineering trade-offs include coolant pressure drop, pumping energy, flow distribution and the possibility of channel fouling.

Beyond thermal hardware, Wiwynn and Wistron said they are among the first NVIDIA pilot-build partners for the Vera Rubin NVL72 platform. That architecture combines 72 Rubin GPUs and 36 Vera CPUs with sixth-generation NVLink in a liquid-cooled rack. Wiwynn also described its AMD Helios integration work, using AMD Instinct MI450-series GPUs, sixth-generation EPYC processors, Pensando networking and ROCm software. These are platform plans and engineering-validation activities, not independent benchmark results.

Optical connectivity is another part of the showcase. Wiwynn, Ayar Labs, Corning, GUC and Senko are presenting a co-packaged-optics scale-up rack concept with fiber routing, patch-panel integration and optical-engine telemetry. Such designs seek to move high-bandwidth communication closer to computing hardware, but maintainability, interoperability and field repair remain important questions.

The broader pattern is visible across this week’s industry announcements. NVIDIA’s open Vera Rubin rack designs, LITEON’s 1 MW power rack and Delta’s high-density cooling and 800 VDC plans show how the industry is redesigning entire racks rather than simply replacing GPUs.

For operators, these announcements highlight a practical question: can high-density hardware be deployed and serviced reliably at scale? Better cold plates are useful only when paired with adequate facility heat rejection, coolant chemistry, leak detection, pumping, power distribution and trained maintenance procedures. Independent measurements under defined conditions will be needed to compare the new approaches fairly.
