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...]
Book Review of Electronics Cooling (2016)
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling Online Electronics cooling engineers and designers are used to one constant in their professional lives: change. Most of it (as far as problem solving is concerned) is change for the worse… and is challenging! The heat flux keeps increasing, the geometries keep shrinking, the available solution … [Read more...]
Design Considerations When Using Heat Pipes
By George Meyer, Celsia Inc. Introduction This article is intended to offer design guidance when using heat pipes for the most prevalent types of electronics applications: mobile to embedded computing and server type applications with power dissipation ranging from 15 W to 150 W using processor die sizes between 10 mm and 30 mm square. Discussion is constrained to … [Read more...]
How to Choose the Right Solution for Effective Heat Management
(June 3, 2016) Because electronics have shrunk significantly in recent years, the solutions to cool them must be adjusted. Electropages.com suggests “a case-specific analysis must be performed as each application is subject to different circumstances,” to determine the right strategy for cooling electronics. This analysis is called “CFD analysis,” or computational fluid … [Read more...]
New Orders for Indian Satellites’ Heat Pipes
(May 27, 2016) More orders have been secured by Avasarala Technologies Ltd, the city-based tier-1 supplier of critical components to strategic sectors, to supply heat pipes for Indian satellites. “As an import-substitute component, the pipes are used in satellites to collect heat generated by electronic devices and release it in space to keep them cool,” said … [Read more...]
