4U CDU (Coolant Distribution Unit)
4U Coolant Distribution Unit
As computing chip power increases, liquid cooling becomes the necessary solution to replace conventional aircooling. Boyd’s new 4U Liquid-to-Liquid Cooling Distribution Unit (CDU) is a state-of-the-art cooling system thatmaximizes cooling capability in its given volume. This benefit increases IT equipment’s packaging density intoa rack while adequately cooling the electronics using Boyd’s cold plates and manifolds.
Depending on heat load and approach temperature requirement, Boyd’s 4U CDU has a typical capacity of 80
kW. With industry-standard liquid ports and electrical connections, the system is ready for quick field installationand effortless operation. The 4U CDU has high reliability with built-in N+1 redundancies with power supply andpumps. The large LCD provides easy parameter controls and displays.
Whether you need a CDU for data center deployment, system burn-in testing, or development lab testing, thisproduct will provide worry-free cooling. This unit seamlessly works with Boyd’s rack manifold and cold plateloops for a complete end-to-end liquid cooling solution.
