Fan Cooling – Part 1: Determining Flow Rate
Authored by Ross Wilcoxon and Genevieve Martin Associate Technical Editors for Electronics Cooling For a number of reasons, including cost, simplicity, power consumption, noise, etc., natural convection is the preferred approach for cooling electronic systems. However, it is often the case that natural convection is simply not sufficient to remove dissipated power … [Read more...]
Statistics Corner: Regression Analysis
Throughout their careers, engineers and scientists are all likely to encounter and utilize the results of regression analysis, which is “a set of processes for estimating the relationships between a dependent variable and one or more independent variables” [1]. In other words, regression analysis uses a set of data to estimate a relationship between the independent … [Read more...]
Real-Time Prediction of Li-Ion Battery Pack Temperature
Co-Authored by: Dr. Azita Soleymani and William Maltz The global shift to electric vehicles (EV) is coming and, unless an alternative technology emerges, it will be fueled by high-capacity lithium-ion (li-ion) batteries. Making the hundreds of millions of li-ion batteries the world will eventually need for e-mobility is a massive undertaking full of technical challenges. … [Read more...]
A Heatsink Remodeling Methodology
The role of a heatsink is to provide a conduction path from a heat source that is to be cooled to a volume of cooling fluid. The heatsink’s surface area that fills that volume is considerably larger than the surface area of the heat source. In this way, the heatsink acts as an ‘area extender’. For a given heat flow (Q) and convective heat transfer coefficient (h), any … [Read more...]
