INTRODUCTION In terrestrial or air-borne electrical and electronic systems, cooling requirements can be unsteady due to spikes in heat load, or changes in ambient conditions. Such an event results in a sharp rise in system temperature or temperature cycling thus possibly reducing the system reliability. In the electrical domain, fluctuations in voltage are managed by using … [Read more...]
Case Study: Thermal Design and Analysis of a Combat-Ready Electronics Unit
INTRODUCTION Militaries continue to expand their use of electronics in harsh environments while preserving an absolute minimal risk of failure. In this regard, effort spent early in the design process on concept development, parametric and trade-off studies, and simulation-driven design can yield amplified benefits in terms of product performance and reliability, reduced … [Read more...]
Cooling the DARPA Space Surveillance Telescope (SST)
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling With many nations joining the race of sending satellites out to space, the number of orbiting space debris is increasing year after year. This NASA portal estimates the number of space junk as over 500,000 orbiting earth at speeds of 17,500mph or higher. Most of the half-million plus objects … [Read more...]
