Electric vehicles are poised for a rapid growth phase with the combined effect of longer range, lower battery cost and faster charging rate. In particular, sales of plug-in electric vehicles (PEV) have tripled since 2013 and continue to grow at over 40% a year. It is expected that at these growth rates, 8 out of 10 new cars sold globally in 2030 will be a PEV. In some countries … [Read more...]
Advanced Cooling for Power Electronics
Power electronics devices such as MOSFETs, GTOs, IGBTs, IGCTs etc. are now widely used to efficiently deliver electrical power in home electronics, industrial drives, telecommunication, transport, electric grid and numerous other applications. This paper discusses cooling technologies that have evolved in step to remove increasing levels of heat dissipation and manage junction … [Read more...]
A Novel Approach to Development of a Thermal Capacitor
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 those … [Read more...]
