Dr Peter De Bock, GE Global Research will give a seminar on 

Dual Piezoelectric Cooling Jet Development at GE Global Research

Monday 11 November 2013, 13:00, Parsons Building (Crossland Lecture Theatre)

Recent years have seen an increasing research activity in the area of synthetic jet cooling for electronics thermal management, both within the Trinity College Fluids & Heat Transfer group and multinational commercial R&D labs such as General Electric (GE) Global Research and others. Dr Peter De Bock is the lead Electronics Cooling Researcher at GE Global Research in charge of developing the Dual Cooling Jet (DCJ) technology. DCJ will support the next generation of thinner, quieter and more powerful tablets, laptops and other electronic devices.

GE’s DCJ (Dual Piezoelectric Cooling Jets) behave as a micro-fluidic bellows that provide high-velocity jets of air to cool electronic components. The turbulent air flow of the DCJ increases the heat transfer rate to more than ten times that of natural convection. A demonstration of the technology is available on YouTube.

GE received the first patent on the technology in 2004, and has gained a dozen more patents since. GE is currently providing DCJ demonstration kits for OEMs wishing to evaluate the DCJ technology for their next generation products, and Peter will bring such a demonstration prototype to the seminar. GE has licensed the DCJ technology to Fujikura Ltd., a world leader in thermal management solutions serving the telecom, automotive, energy, and electronics markets.

GE Global Research is one of the world’s most diversified industrial research labs, employing 2,800 researchers to provide innovative technology for all of GE’s businesses in areas such as medical imaging, energy generation technology, jet engines and lighting. GE Global Research is headquartered in Niskayuna, New York and has three other multidisciplinary facilities in Bangalore, India, Shanghai, China and Munich, Germany. Their technology expertise ranges from electronics to chemistry, biosciences to computing, metallurgy to fluid mechanics, materials to imaging. Peter will be working as visiting research fellow in the Fluids & Heat Transfer group this autumn.
