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...]
transient dual interface measurement of the rth-jc of power semiconductor packages
Dirk Schweitzer Infineon Technologies AG Introduction The junction-to-case thermal resistance Rth-JC is an important thermal characteristic especially for power semiconductor devices. Its value is often one of the main criteria for the decision whether a device can be used in a specific application and a low Rth-JC is a competitive advantage for the semiconductor manufacturer. … [Read more...]
technical brief: thermal bottlenecks and shortcut opportunities; innovations in electronics thermal design simulation
Introduction Cooling an electronics system involves transferring heat from various heat sources to the outside ambient. Thermal simulation software provides practitioners with predictions of the temperature and heat flux distributions in and around the system, making it easy to assess the impact of design changes. While the raw simulation results enable us to measure and … [Read more...]
