Toward a new way to keep electronics from overheating

Summary:
Computer technology has transformed the way we live, but as consumers expect ever more from their devices at faster speeds, personal computers as well as larger electronic systems can overheat. This can cause them to slow down, or worse, completely shut down. Now researchers are reporting that liquids containing nanoparticles could help devices stay cool and keep them running.

Computer technology has transformed the way we live, but as consumers expect ever more from their devices at faster speeds, personal computers as well as larger electronic systems can overheat. This can cause them to slow down, or worse, completely shut down. Now researchers are reporting in the ACS journal Industrial & Engineering Chemistry Research that liquids containing nanoparticles could help devices stay cool and keep them running.

Rahman Saidur and colleagues point out that consumers demand a lot out of their gadgets. But that puts a huge strain on the tiny parts that whir away inside desktops and mainframe computers, which do the major data crunching for us. The result is overheating. Recent research has shown that substances called nanofluids have the potential to help keep electronics cool. They are made of metallic nanoparticles that have been added to a liquid, such as water. But there are many different kinds, and past research on their coolant abilities has been limited. To help sort through them, Saidur's team set out to determine which ones might work best.

Using something called a microchannel heat sink to simulate the warm environment of working electronic systems, they analyzed three nanofluids for the traits that are important in an effective coolant. These include how well they transfer heat, how much energy they lose, the friction they cause and their pumping power. All three performed better than water as coolants with the nanofluid mixture of copper oxide and water topping them all.

The authors acknowledge funding from the Ministry of Education Malaysia.

Crude Oil Prices Bounce Back After Falling Below $100 a Barrel

TheStreet (July 16, 2014) Oil Futures are bouncing back after tumbling below $100 a barrel for the first time since May yesterday. Jeff Grossman is the president of BRG Brokerage and trades at the NYMEX. Grossman tells TheStreet the Middle East is always a concern for oil traders. Oil prices were pushed down in recent weeks on Libya increasing its production. Supply disruptions in Iraq fading also contributed to prices falling. News from China's economic front showing a growth for the second quarter also calmed fears on its slowdown. Jeff Grossman talks to TheStreet's Susannah Lee on this and more on the Energy Department's Energy Information Administration (EIA) report. Video provided by TheStreet
