Figure 1: Heat pipe operation Introduction All electronic components, from microprocessors to high end powerconverters, generate heat and rejection of this heat is necessary for theiroptimum and reliable operation. As electronic design allows higher throughputin smaller packages, dissipating the heat load becomes a critical design factor. Many of today's electronic devices … [Read more...]
Thermal control of space electronics
Introduction Telecommunication satellites are all based on the same overall design usinga 3 axis stabilization process, in which the North and South panels act asradiators and so ensure heat removal. This basic principle is illustrated in Figure 1. The ever-increasing demandfor national and international space-based communications in parallel with theevolution of space … [Read more...]
Applying computational fluid dynamics to heat sink design and selection
Abstract This article describes how Computational Fluid Dynamics (CFD) can help inthe selection and/or design of a heat sink for electronics cooling applications.CFD modeling complements the other tools in the thermal tool kit: calculationsbased on approximations and correlations; and experimental work. Whether theapplication includes single or multiple heat sinks, the … [Read more...]
