Abstract
This disclosure describes techniques for improved flow-rate control in liquid cooling systems that are used in thermal management of data center racks. Per techniques of this disclosure, proportional solenoid valves (also known as solenoid control valves) are used for flow-rate control in data center liquid cooling applications. By adjusting the PWM duty cycle, a control system can control the liquid flow to achieve a target temperature of a device being liquid cooled. In some implementations, the valve is placed directly inside the server tray and control signals to perform flow-rate control are provided by a tray-level motherboard. In some implementations, the proportional solenoid valve can be located on the rack itself, at the slots where each tray is plugged into the data center rack. This configuration allows for centralized control and management, with control signals originating from either the tray and/or the rack management unit.
