By Serdar Ozguc, Qingyang Wang, Akshith Narayanan, Richard W. Bonner III The Need for Two-Phase Cooling in Data Centers Power usage in data centers account for 1.8% of the overall electricity expenditure in the United States [1] and the cooling infrastructures make up 50% of the total energy consumption of the data centers [2]. Power consumption translates to high … [Read more...]
Augmenting Development of Electronics Cooling Technologies with Machine Learning Tools – a Heat Pipe System Example
The traditional pathway for development of thermal management technologies for electronics has been to analyze using heat transfer theory augmented by computational tools such as finite difference or finite element methods, CFD tools, or thermal management system simulation tools, sometimes in tandem with prototype system fabrication and testing. Combining recently available … [Read more...]
Hydraulic and Thermal Characteristics of a Double-Sided Cold Plate – Part 2
Tesla Tear Down, CFD Validation, and Machine Learning to Determine the Performance Limit This study investigates the hydraulic and thermal characteristics of the TESLA AUTOPILOT HW2.5 MODEL 3 Y, which features a double-sided cold plate with PCBs attached on both sides. We present a step-by-step teardown process of the unit, measuring internal dimensions, fin locations, … [Read more...]
How Many Ways Can Temperature Affect Performance and Reliability of Electronic Systems?
Thermal management in high performance electronics has become a leading challenge for design and reliability engineers. Harsh temperatures can be caused either by harsh operational conditions (high power dissipation), or by harsh environmental conditions. Both require adequate thermal management to ensure that the product temperature stays within acceptable limits. High … [Read more...]
Will PFAS be the Death of Two-phase Cooling?
At this year's Thermal Live Spring Summit, Inventec discussed a pivotal topic — PFAS (per- and polyfluoroalkyl substances) and their crucial role in cooling systems extensively used by data centers. This topical content springs debates about alternative approaches such as 2 phase immersion cooling, regulation of PFAS across various regions, concerns related to the health and … [Read more...]
