Coolant Distribution Unit (CDU) for AI & HPC Cooling

A coolant distribution unit is a core component of liquid cooling infrastructure for high-density computing environments. It manages coolant circulation between the facility cooling system and technology-side loops serving server racks or processor-level cooling equipment. Depending on the architecture, a CDU can include pumps, heat exchangers, manifolds, valves, filters, sensors, controls, and monitoring interfaces. In direct-to-chip applications, it can deliver coolant to CPU, GPU, and accelerator cold plates while collecting warmed fluid through dedicated return paths. Important design parameters include total thermal load, coolant flow rate, supply and return temperatures, operating pressure, pressure drop, fluid properties, heat exchanger capacity, rack density, and the number of connected cooling circuits. CDUs are applicable to AI data centers, HPC facilities, cloud infrastructure, telecom systems, and enterprise server environments. A modular configuration can support current cooling requirements while providing connection options for future rack expansion.
