en.Wedoany.com Reported - Google has released a closed modular liquid cooling system called Brazos, designed to enable high-density liquid-cooled equipment deployment in existing air-cooled data centers. The system transfers component heat to a "hot aisle" via air-to-water heat exchangers, while its cooling circuit operates independently of the building's main water supply, allowing rapid installation in most existing data centers, provided sufficient spare power and ventilation are available.

Brazos is a modular system consisting of three cooling units (11 OU) and built-in rack manifolds, compatible with standard OCP ORv3 racks. Technical specifications: With three cooling modules in operation, it can handle a nominal thermal load of 60 kW; the coolant uses deionized water or 25% propylene glycol solution (PG25); power supply is 40–60 V DC, directly connectable to standard rack power busbars; the system is certified to UL/CSA/IEC 62368-1 standards and is equipped with integrated leak sensors and pressure relief valves; local management is via an built-in human-machine interface, while remote management uses the Modbus TCP protocol.

The system chassis is mounted on specially designed "low-friction" slides for quick maintenance access. Key components such as pumps and fans are designed as hot-swappable FRU modules to reduce mean time to repair, with the overall structure optimized for on-site serviceability. Google plans to open-source the Brazos technical documentation in the coming months. This project is a key part of the company's strategy to combine the advantages of air cooling and liquid cooling, aiming to help server hardware manufacturers adapt to the rapid growth of modern chip TDP.
