By Cameron Koller, Marketing Development Manager, Parker Hannifin Quick Coupling Division As technology evolves, one challenge remains constant: heat. Servers, supercomputers, and data centers generate massive amounts of heat, with power densities often reaching 10 to 20 kilowatts per rack and, in some cases, significantly exceeding 50 kW in high-performance computing … [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...]
Tech Brief: Environmental Effects on Thermocouples
When selecting a sensor, one should consider whether the environment in which it is to be used will cause a measurement error. As part of this series on thermocouples, this article discusses a few environmental effects that can alter the structure of the materials that make up a thermocouple and thereby affect their accuracy. This degradation of thermocouple accuracy is … [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...]
Simulation of Solder Fatigue Effects on Typical BGA Package due to Material and Temperature Variations – Part 1
Abstract The past two decades have seen many approaches to solder fatigue and solder joint life published. This subject has proved difficult as various failure mechanisms are proposed and examined. While these theoretical bases are discussed, it often leaves the end developer in a difficult situation as to how to apply an accurate simulation approach to fatigue failure for a … [Read more...]
