Sandia National Laboratories announced that their Sandia Cooling technology has been licensed by two companies, bringing the Sandia Cooler heat sink much closer to the production phase. According to the company, the redesigned architecture for the air-cooled heat exchanger "simultaneously eliminates all three drawbacks of conventional air-cooled heat exchanger … [Read more...]
Designing Heat Sinks When a Target Pressure Drop and Flow Rate is Known
Forced convention air cooled heat sinks and liquid cooled cold plates are quite pervasive in their use in electronics cooling applications. While there can be significant debate on whether to air or liquid cool a particular component, the approach a thermal engineer would adopt to design both components is essentially similar. Parallel plate fins are the most common geometry … [Read more...]
Silicon Carbide’s Potential in Hybrid and Electric Vehicles
Encouraged by silicon carbide’s superior material properties, major automotive manufacturers involved in developing hybrid and electric vehicles are currently testing SiC-based MOSFETs and other transistors as a viable alternative to silicon-based transistors, particularly for under-the-hood applications where the operating conditions are challenging. The wide-bandgap material … [Read more...]
Multi-Port Cages with Thermal Management
dataMate™, a division of Methode Electronics, Inc.’s Data Solutions Group, announced the development of a patent pending SFP+ cage system with advanced thermal management features to prevent data error and hardware failure due to excessive heat. dataMate™ has developed a new cage system which utilizes a series of thermally conductive compliant fingers that make direct contact … [Read more...]
Cooling LEDs with Air Instead of Heat Sinks
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...]
