The SynJet® cooler is a plastic housing surrounding an oscillating diaphragm. This oscillating diaphragm and associated housing creates pulses of high velocity turbulent air flow. This high velocity flow “entrains” or pulls air in its wake, increasing the overall air flow by as much as five times. This turbulent air flow improves the heat transfer out of the heatsink locally while the entrained air sweeps the hot air out of the system, thus cooling the LEDs. Synthetic jet modules are inherently reliable because they have no frictional parts to wear out and cause failures. A technology flash demo is available on the Aavid Thermal Division of Boyd website for further details on the unique SynJet operation.
