Stepped-Function Flow Control for Liquid Cooling

Low power consumption and predictable, repeatable flow rates are combined in one valve system.

Customer Problem

Many liquid-cooling thermal systems have to manage heat from multiple sources simultaneously, which often have differing heating and cooling requirements. These systems usually rely on electrically actuated proportional valves to control the flow of coolant. With many applications focusing more heavily on maximizing overall energy efficiency, OEMs and system suppliers are discovering that many proportional flow control valves lack the ideal combination of attributes, including predictably repeatable flow rates and minimized electrical consumption.

The TLX Solution

TLX developed the Discrete Proportional Valve System (DPV), which uses two or more binary (on-off) valves of differing flow coefficients in a single manifold to provide stepped-function flow control. The valves are actuated in specific combinations to achieve the desired flow rate and draw no current to maintain position. This design delivers zero hysteresis, meaning the flow coefficient for any given flow rate is the same regardless of whether the flow rate is increasing or decreasing.
