Brazos liquid cooling system for air-cooled data centers
Next-generation artificial intelligence (AI) and high-performance computing (HPC) chips routinely exceed 1000 W Thermal Design Power (TDP). Simply put, standard air cooling cannot manage these extreme heat loads. The alternative — retrofitting entire data center facilities with chilled water loops — requires extensive amounts of capital and time. To solve this problem, Google developed Brazos, a rack-mounted, closed-loop liquid-to-air cooling system that lets you deploy high-density, liquid-cooled equipment inside existing air-cooled environments. Brazos is generally available, and our manufacturing suppliers are ready to engage the broader industry to market and produce the Google Brazos design.
Data center facility updates can take months. Brazos breaks with this by allowing simple, one-rack-at-a-time installations. By separating the internal-to-IT liquid loop from the facility water supply, Brazos delivers high-performance liquid cooling with the operational simplicity of standard air systems.
