Interactive Tools
Coolant Distribution Unit (CDU) Sizing Tool
This tool is designed to size a Coolant Distribution Unit (CDU) for a direct-to-chip liquid cooling system. It calculates the necessary fluid temperature, total flow rate, and total pressure drop across cold plates in a cooling loop. This serves as a preliminary guide to facilitate better understanding and communication between buyers and sellers, helping to reduce the learning curve and bridge the knowledge gap in selecting the appropriate CDU for a server.
