Synthetic Jet Technology

Nuventix has developed a patented synthetic jet for active cooling of electronics that produces 30 to 200 turbulent air pulses per second. This pulsatile flow breaks up the fluid and thermal boundary layers that inhibit heat transfer from an electronic heat source to the cooling air flow. Lower acoustic noise and power is claimed compared to conventional fan cooling. Visit the Nuventix website for more details and an excellent Flash demo of the synthetic jet description of operation. A nice overview article is also available in the Spring 2009 issue of Thermal News.
