ZutaCore unveiled Two-Phase Matrix Flow Boiling, the cooling architecture inside its OmniTherm cold plate family, at OCP Global Summit 2026 on Oct. 13. The Foster City, California, company builds waterless, direct-to-chip two-phase liquid cooling for AI and high-performance computing servers. The anno
uncement arrives as chip power has roughly tripled in three generations, with multi-kilowatt packages reaching the market.
ZutaCore says the design uses a distribution manifold that feeds liquid straight down onto many small boiling regions across the die, while vapor escapes straight up from each region. The company states the arrangement holds the hottest AI chips, and the hot spots that move within them, at a uniform temperature. Because each region regulates its own boiling locally, ZutaCore says the cold plate needs no active flow control and works in any mounting orientation.
The form factor is central to the pitch. ZutaCore says the boiling stack is under 5 mm thick, enabling cold plates as thin as 11.6 mm. That opens single-slot PCIe cards, sub-1RU servers, and accelerators mounted on the underside of the board. A hybrid copper-aluminum construction brings weight down to as little as 300 grams, which ZutaCore says carries no risk of galvanic corrosion.
ZutaCore states the loop needs 0.6 to 0.7 liters per minute per kilowatt, against 1.5 to 2.0 for single-phase cooling. The sealed dielectric fluid is non-conductive, so a leak puts fluid on the board rather than requiring a board replacement, according to the company.
"AI cooling is now an end-to-end system challenge: you have to cool the silicon while keeping entire racks and rows stable," said My D. Truong, Chief Product and Technology Officer at ZutaCore. "Matrix Flow Boiling combines the stability of pool boiling with the scalability of flow boiling, so cooling responds exactly at the location of heat creation."
OmniTherm deployments are underway this quarter for the NVIDIA RTX PRO 6000 Blackwell Server Edition, ZutaCore says. As the next-generation cold plate for ZutaCore's HyperCool, OmniTherm uses the same fluid, connections, racks, and coolant distribution units proven across more than 75 deployments. ZutaCore has deployed two-phase pool-boiling cold plates in commercial high-performance computing systems for nearly a decade, per the company. ZutaCore displayed the cold plate at its OCP booth and at the summit's Innovation Village, and Wiwynn showed the OmniTherm cold plate at its own booth.
Baxtel tracks 170 data center facilities in the San Francisco Bay Area, where the market holds 1,051 megawatts and 12 sites are under construction.
ZutaCore says a development program is under way with partners to move the boiling regions into the chip package and, eventually, onto the silicon itself.
