Supermicro expands its end-to-end DCBBS liquid cooling portfolio by introducing rear door heat exchangers aimed at high-density AI and HPC deployments. The company says the expanded lineup includes ten models designed to address cooling needs across a range of capacities, from systems-level configurations to rack-scale deployments. It states that the rear door heat exchangers support chilled-door capacities spanning 10 kW to 120 kW. Supermicro also positions the solution as suitable for both new and legacy data centers, emphasizing low-disruption installation and rapid heat transfer through rear-door integration. In its announcement, the company ties the expanded cooling offerings to its DCBBS approach, noting that integrated components are intended to be validated as part of an overall cooling system. Coverage across the provided sources focuses on the product expansion and its intended use cases—AI factories and HPC infrastructure—along with the stated capacity range and compatibility with existing data center environments.
