Study of Fluid Velocity Limits in Cold Plate Liquid Cooling Loops for Data Centers

Explore a technical presentation examining the erosion behavior of copper and EPDM hoses in direct-to-chip liquid cooling systems for data centers. Learn how researchers investigate the ASHRAE-recommended flow velocity limit of 1.5 m/s through experimental analysis using advanced measurement techniques. Discover the methodology behind testing coolant flow rates of 1.8 m/s in 3/8" ID hoses and 2.62 m/s in copper cold plates at elevated temperatures, while understanding how Inductively coupled plasma mass spectrometry, scanning electron microscopy (SEM), and optical microscopy are used to analyze coolant properties and surface topography. Gain insights into addressing cooling challenges for high-performance processors in modern data centers through this research conducted by experts from 1547 Datacenters and Nvidia.
