Researchers have shown that an advanced cooling technology being developed for high-power electronics in military and automotive systems is capable of handling roughly 10 times the heat generated by conventional computer chips, according to a research paper appearing online in the International Journal of Heat and Mass Transfer. Written by mechanical engineering doctoral … [Read more...]
Hybrid’s Liquid System Allows Chevy to Offer Cool Warranty
The liquid heating and cooling system in the Chevrolet Volt battery not only enabled General Motors Co. to offer a long warranty of eight years or 100,000 miles, but it also gave engineers more room for battery cells since it’s more compact than air-cooled systems, but it also. Standard auto coolant circulates through 144 metal plates, called fins, between each of the Volt … [Read more...]
The Uses of Simplicity in Thermal Analysis
Bruce Guenin, PhD Editor-in-Chief, Summer 2010 Issue The dramatic trajectory of Moore’s law has produced a number of changes in key areas of technology that are critical to our industry: 1) greater packaging and system complexity; 2) increased power dissipation; and 3) enhanced software tools and computing performance. The first two we put into the challenge category. They … [Read more...]
