Thermal solutions provider JMC products has released two new counter-rotating fans measuring 40x50x32mm and 40x50x38mm for high-density 1U servers, power supplies and high-density electronic enclosures. Both fans feature a speed of 10,200 rpm and pulse width modulation (PWM) control for both motors individually or simultaneously. … [Read more...]
“Transverse” Thermoelectric Effect May Lead to Better Cooling Devices
Northwestern University researchers are investigating the possibility of vertical heat transport for better cooling devices. A new paper published in Physical Review Letters by researchers at Northwestern University in Illinois explores the idea of using materials in which heat flows perpendicular to an electric current to develop better devices for cooling … [Read more...]
Effectively Leveraging CAD Data in Electronics Thermal Simulation
June 26, 2013 Online "CFD modules embedded within MCAD software utilize native geometry but fail to deliver on solver speed, stability and built-in intelligence. Application specific CFD tools utilize parametric modeling objects allowing users to quickly create typical electronic components (PCBs, heat sinks, fans etc.). However, these advances are lost when importing … [Read more...]
Beware… When Cooling Practices Fail! Webinar Part II
June 25, 2013 Online In this webinar, "Ramzi Namek and Eric Fournier of Total Site Solutions, will present an actual customer situation they were called in to assess: a partially-contained hot aisle was seemingly causing hot air to appear at the front of the racks—a problem that had not been there before! The Total Site Solutions team used the 6SigmaRoom software to study … [Read more...]
Not Needing to Adjust Hot-Wire Anemometer Reading for Elevated Temperatures. Why Not?
Editor’s note: This question was asked in response to Electronics Cooling’s recent webinar by Roger Stout. To view the webinar, click here. Question: I've never heard that about not needing to adjust hot-wire anemometer reading for elevated temperatures. Why not? Answer: I don't know, luck? I published one paper on the subject, but it was really incidental, since we didn't … [Read more...]
