A paper on thermal aspects in power systems won a Young Engineer Award at this year’s PCIM (Power Electronics/Intelligent Motion/Power Quality) Europe Conference. The Young Engineer Award is presented to exceptional contributions from young professionals (under 35 years old). Andreas Munding of Liebherr-Elektronik GmbH and his co-authors were recognized for their paper, … [Read more...]
ElectronicsCooling Spring 2010 Print Issue
Did you miss us? For those of you that are faithful readers of Electronics Cooling, we are pleased to inform you that after a short interval of restructuring, we have resumed publication. Given the recent downturn in the economy as a whole, and specifically within the electronics thermal management community, we can hope that this is a sign of improvement and recovery. We will … [Read more...]
thermal facts and fairy tales: most of us live neither in wind tunnels nor in the world of Nusselt
Having read myriad papers/articles/books/reports on thermal management, I feel there is a lot of misunderstanding about what really should drive a sound approach of how to tackle the thermal problems that tend to land on the desk of thermal designers. I also have the feeling that many “how to” articles presented on the Web are just meant to show off the knowledge of the author … [Read more...]
a case study to demonstrate the trade-offs between liquid and two-phase cooling schemes for small-channel heat sinks in high heat flux applications
Introduction Small-channel heat sinks provide an extremely compact and efficient vehicle for dissipation of large heat fluxes typically found in high power electronics. Fluid flow and heat transfer in small-sized channels, with hydraulic diameters on the order of a fraction of a millimeter (a few hundred micrometers), have been shown to behave similarly to conventional-sized … [Read more...]
Researchers Cool Down Supercomputers with Warm Water
A team of IBM researchers in Switzerland is experimenting with a micro network of copper tubes that run through smaller, clustered computer servers and whisk away heat with the help of warm water. Liquid cooling, even with warm water, is 4,000 times more effective than air cooling at removing heat, they say. Researchers from IBM and the Swiss Federal Institute of Technology in … [Read more...]
