Miba, a partner to the international engine and automotive industry, has acquired two Austrian producers of power electronics components such as resistors and cooling systems for power electronics. EBG, based in Styria, Austria, is a specialist in passive electronic components, such as high-voltage, high-performance resistors, and generates annual sales of €30 million. DAU is … [Read more...]
Nanofluid Tapped to Cool Servers
Scientists at Sweden's Institute of Technology have developed a nanofluid solution that could eventually be used to cool massive data centers and server farms. Researcher Mamoun Muhammed told CNN that his team had experimented with various nanoparticles, but the ones currently showing the most potential are oxides of metals such as zinc and copper. However, carbon nanotubes are … [Read more...]
Graphite Foam Promises Longer-Lasting LEDs
A new graphite foam cooling system developed at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) in Tennessee may soon allow LED lamps to go much longer between fixture replacements. The graphite foam works by passively wicking heat away from the lamp via its lightly packed, open skeletal structure – and given that a 10-degree decrease in operating temperature … [Read more...]
editoral: why standardization is mandatory: on the incorrect use of thermal impedance in the TIM world
Clemens J.M. Lasance Editor-in-Chief, Fall 2010 Issue Some time ago I devoted my editorial to the problems caused by the veeerrryyy slow adherence to the use of SI units to which the U.S. committed itself in 1872. When talking globalization we should speak the same scientific language, and when there are conflicts of interest, logical reasoning should prevail to decide upon … [Read more...]
calculation corner: a spreadsheet based matrix solution for a thermal resistance network: part 1
Ross Wilcoxon Rockwell Collins Cedar Rapids, Iowa A thermal resistance network analysis begins by defining discrete points within a system, known as nodes, and the thermal resistance between each set of nodes. Boundary conditions for external heat inputs and reference temperature(s) are applied to the appropriate nodes. Equations to relate nodal temperatures can be generated … [Read more...]
