Technical Brief: Design Considerations for High Performance Processor Liquid Cooled Cold Plates
The meteoric rise in cooling requirements of commercial computer products has been driven by an exponential increase in microprocessor performance over the last decade. The conventional way to cool microprocessors has been to utilize air to carry the heat away from the chip, and reject it to the ambient. Air cooled heat sinks are the most commonly used air-cooling devices with … [Read more...]
Thermal Modeling and Testing for LEDs and Luminaires
Mentor Graphics Corp. has introduced the T3Ster (“trister”) thermal transient tester for LEDs, board-level LED arrays and luminaires. Together with the company’s FloTHERM thermal simulation tool based on computational flow dynamics (CFD), lighting designers can model and improve heat transfer through the LED, printed circuit board (PCB) or luminaire system during design and … [Read more...]
New Law Focuses on Rare Metals in Electronics
A provision on "conflict minerals" that was slipped into a 2010 financial reform law, the Dodd-Frank Act, will help educate American consumers on what is in their smart phones, computers and other electronics and where U.S. electronics manufacturers are getting those rare metals. In the jungles and mountains of the Democratic Republic of the Congo, armed groups have been … [Read more...]
Tiny Solar Cell Saves Money and Energy
The U.S. Department of Energy's National Renewable Energy Laboratory recently validated greater than 41 percent efficiency at a concentration of 1,000 suns for tiny cells made by Semprius. The energy conversion efficiency of a solar cell is the percentage of sunlight converted by the cell into electricity. Seed money from DOE, together with the experts at the NREL-based … [Read more...]
