Power densities in electronic subsystems continue to increase, driving demand for more extreme cooling power alternatives that increasingly include liquid cooling as a viable candidate. To optimize thermal management efficiency, sustainability and reliability, designers of systems that use liquid cooling are exploring innovative combinations of component materials, including … [Read more...]
Confidence Intervals
The previous articles in this series [1, 2] described how the mean and standard deviations of a set of data are calculated and how they can be used to estimate the characteristics of a population using the normal distribution. Since measured data typically represents only a subset of an entire population, one should recognize that the estimated mean and standard deviation … [Read more...]
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...]
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...]
Generative Design for Electronics Cooling
Co-Authored by: Danny J. Lohan, Yuqing Zhou, and Ercan M. Dede Toyota Research Institute of North America INTRODUCTION Generative design is an iterative design process that involves the use of a program to generate a set of optimized designs that meet product performance requirements and constraints. Methods that transform statements of performance requirements into … [Read more...]
