Coolant Distribution Units (CDU) for AI & HPC Data Centers

Coolant distribution units are designed to manage liquid coolant between cooling sources and high-density IT equipment. A CDU can circulate fluid, distribute it across multiple cooling branches, and collect warmed coolant for heat rejection or recirculation. Depending on the architecture, the system may include pumps, heat exchangers, manifolds, valves, filters, sensors, controls, and monitoring interfaces. Direct-to-chip cooling systems can use CDUs to supply coolant to CPU, GPU, and accelerator cold plates through dedicated rack-level loops. Key design parameters include thermal load, coolant flow rate, supply and return temperatures, operating pressure, pressure drop, fluid compatibility, heat exchanger capacity, number of connected racks, and future expansion requirements. Coolant distribution units can support AI data centers, HPC clusters, cloud computing facilities, telecom infrastructure, and enterprise server environments. Their modular configuration allows cooling capacity and distribution connections to be planned around current and future high-density computing requirements.
