Post-Forming Extruded Profiles for Heat Transfer Applications Resulting in High Efficiency Cooling
Published Tuesday, April 14, 2009A majority of electronic devices are comprised of circuit boards with multiple heat generating chips of different height. Usually, machined high specification aluminum conduction plates or separate heat sinks are used for each chip. However, machined conduction plates are expensive and the use of separate heat sinks is complicated. Both have...

Flexible-Actively Controlled Heat Exchanger Based on Thin-Film Technology
Published Wednesday, May 7, 2008The microscale heat exchanger manufactured using the wafer technology can’t be scaled for large applications. Also macroscale heat exchangers are usually rigid and require fins to have a secondary heat transfer area for better heat transfer on the air side. Besides, installing bypass valves and temperature sensor in conventional heat exchanger can...
