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...]
The Debate about Liquid Cooled Data Centers
I’ve been remiss in not posting for a couple of weeks, so I’m trying to get back in the saddle. I’ve been working on other things that have taken up a fair bit of time. One is a web seminar on heatsinks – Heatsink 201 – Even More about Heat Sinks which follows on from Alexandra Francois-Saint-Cyr’s very successful Heat Sink 101 web seminar. Back in March I posted about IBM’s … [Read more...]
Tiny Technology Making a Big Splash
Thermacore, Inc., a provider of heat pipe technology and other thermal management solutions, announced that Thermacore Europe is making progress as lead partner of an 8.3 million euro ($11.4M) European research project, NanoHex. The team is tasked with developing a next-generation liquid coolant that incorporates purpose engineered nano-particles for more efficient … [Read more...]
