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...
