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...]
Thermal Resistance Comparison Of Graphite Foam, Aluminum, And Copper Heat Sinks
Introduction With thermal solutions becoming more challenging, there is a push for novel cooling ideas or materials to further mitigate thermal issues facing today's electronics. In these design situations, the proven method of analytical calculations, modeling, and laboratory testing is sometimes bypassed in the search for a quick "cure-all" solution. Evolutionary progress is … [Read more...]
