A little over a pandemic ago, the first article in this series on statistical analysis mentioned that a fundamental aspect of statistics is that one assumes a mathematical model that describes the distribution of a data set and then uses that model to estimate the probability that a given value or set of values will occur [1]. This allows us, for example, to estimate whether … [Read more...]
Thermal Comfort Considerations for Electronics Cooling and Design
Written by: Mark Hepokoski, ThermoAnalytics and Alex Ockfen, Meta Reality Labs Introduction ASHRAE defines thermal comfort as “that condition of mind that expresses satisfaction with the thermal environment” [1]. While engineers and designers are typically familiar with the thermal safety and compliance standards required in their industry [2], thermal comfort is less well … [Read more...]
Heat Transfer and Pressure Drop Correlations for Manifold Microchannel Heatsinks
Written by: Sevket U. Yuruker, Raphael K. Mandel, Amir Shooshtari and Michael M. Ohadi - Department of Mechanical Engineering, University of Maryland Conventional microchannel cooling has been proven capable of removing high heat fluxes, but usually at significant pressure drops. On the other hand, manifold microchannel systems offer high heat transfer coefficients/heat … [Read more...]
Breaking Grounds with Generative Design for Two-phase Cooling of Electronic Devices
Since the size of electronic components keeps on decreasing, the need for improved heat dissipation on these components keeps increasing. This dichotomy presents thermal engineers with a formidable challenge: how to design smaller coolers that dissipate more heat. Adding to the challenge, the fast-paced evolution of electronics means that the development time for the new cooler … [Read more...]
Thermal Management of Integrated Traction Drives in Electric Vehicles
This article reviews integration approaches and, by employing finite element analysis (FEA), compares thermal management solutions for the combined electric motor and power electronics systems for electric vehicles. Integration of power electronics into the electric motor helps achieve higher power densities in the electric traction drive systems. The benefit of integration … [Read more...]
