This paper presents a multiphysics analysis of a space-based communication satellite antenna. Electromagnetic losses due to induced high-frequency surface currents lead to partial, asymmetric heating of the structure, causing stress and deformation. A final electromagnetic analysis is performed on the resulting deformed structure to determine the effect of the deformation on … [Read more...]
Computers that Recycle Energy among Top IT Innovations
Computers that can recycle energy are among the scenarios IBM Corp. predicts over the next five years as part of its annual “Next Five in Five” year-end innovations report based on technologies being developed in IBM labs and around the world. On-chip water-cooling systems could be used to utilize thermal energy from a cluster of computer processors to provide hot water for an … [Read more...]
Heat Pipe-Assisted Heat Sinks for Power Electronics Cooling
Advanced Cooling Technologies Inc. (ACT) in Lancaster, Pa., is introducing the heat-pipe-assisted HiK Plate heat sinks for power electronics cooling applications involving insulated gate bipolar transistors (IGBTs), thyristers, intelligent power modules (IPMs), symmetric gate commutated turn-off thyristors (SGCTs), and silicon controlled rectifiers (SCRs). Power electronic … [Read more...]
Beer Fridge – A Case Study in Thermal Design. Part 2 – TEC Effect
Beer drinkers are notoriously quiet people and as such would not want to be disturbed by the continuous hissing and whirring of a classic compression/expansion refrigeration cycle type beer fridge. They would argue that’s why both kids and kitchens were invented. Kitchens to put the noisy fridge in, kids to go get the next beer. Electric coolers, fridges that utilise … [Read more...]
