Steady state operating temperature is a critical design parameter for ensuring the reliable operation of modern electronics systems. However, in practice it is but one of many factors that impact overall system health and performance. Modern challenges, like the large transient power draw associated with artificial intelligence (AI) workloads create the potential for more … [Read more...]
Regulating Temperatures in Electric and Hybrid Vehicles: THERM-A-GAP CIP 35E
Electric vehicles (EVs) and hybrid vehicles (HEVs & PHEVs) are becoming increasingly prevalent to reduce the environmental detriments produced by traditional combustion engine (ICE) vehicles. The use of stored electrical energy as opposed to stored chemical energy (gas) requires the use of large battery packs to supply the electric drivetrain, and therefore the electric … [Read more...]
Measuring the Thermal Conductivity of Anisotropic Heat Spreading Materials
By: Aaditya A. Candadai, Aalok Gaitonde, Shanmukhi Sripada, Justin A. Weibel, Amy M. Marconnet Introduction New high thermal conductivity materials have been developed to enable enhanced heat transport within electronics packages and other thermal management applications. Many of these engineered materials have anisotropic thermal properties inherent to their fabrication, … [Read more...]
Radiation Basics: Making Sense of Emissivity & Absorptivity
Introduction This is the second installment in a series of articles that aims to explore a range of practical topics on radiation that are relevant to those of us focused on electronics cooling and thermal design. The last article [3] provided guidance regarding when radiation matters, with examples being natural convection environments, space applications, solar collectors, … [Read more...]
