Precision Flow Control for Direct-to-Chip AI Cooling

In high density AI systems, maintaining stable flow at the chip is critical to achieving consistent cooling performance. However, traditional fixed restrictors tie flow directly to pressure, making flow rates vulnerable to changing operating conditions.

This side-by-side demonstration compares a fixed restrictor with The Lee Company’s Flow Regulating Valve across a range of operating pressures. Using real-time flow measurements, the video shows how the Flow Regulating Valve maintains a consistent flow rate as system pressure changes, helping improve thermal stability and reduce the risk of performance-limiting hot spots and throttling.
