Zeta LED has developed an air-cooled LED light bulb. The Lifebulb consumes 10 watts of power and puts out as much light as a standard 60 watt incandescent, pretty much like existing LED bulbs. The difference comes in the absence of an aluminum heat sink. Zeta keeps its bulb cool by channeling air through the vents in the structure itself: the vents are the strips and holes … [Read more...]

Air-Cooled, Pin Fin Coldwall Design For Operation At Altitude
Introduction Numerous thermal management techniques exist depending on the system, application, and power level. For airborne electronic systems, the most direct approach to thermal management would be to use ambient air or chilled air, provided by the aircraft, routed to and blown across the electronics. However, in some applications potential contaminants in the cooling air, … [Read more...]
