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...]
Thermal Conductivity & CTE of Materials: Can We Engineer Them?
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling Online Most electronics cooling problems are not just limited to the computation of temperatures at various points and the design remedies thereof. They also extend to managing the collateral effects of temperature fluctuations. One such effect is the mobilization of thermomechanical stresses in … [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...]
Tech Brief: Commercially-available Thermally Enhanced Polymer Composite Materials Characteristics
Peter Rodgers, Editor Valérie Eveloy, The Petroleum Institute Introduction The development, characterization, and implementation of polymer composite materials for the thermal management of electronic equipment has recently began to attract attention [1,2]. The enhanced thermal conductivity, low density, low cost, ease of manufacture and corrosion resistance of polymer … [Read more...]
