A well-known method of making heat sinks for electronic devices is a process called sintering, in which powdered metal is formed into a desired shape and then heated in a vacuum to bind the particles together. In a recent experiment, students at MIT led by Kripa Varanasi, d’Arbeloff Assistant Professor of Mechanical Engineering, tried sintering copper particles in air and … [Read more...]
Low Resistance Connector with Silicone Core
Fujipoly’s Zebra® Gold 8000C Series product is constructed from a low durometer silicone core that is covered with 166 parallel rows of flat, gold-plated wires per inch. This construction allows the connector to accommodate PCBs with pad center spacing down to .020”. In addition, each .001” x .003” gold-plated copper element delivers a current carrying capacity of 250mA while … [Read more...]
Multiple Platforms CPU Cooler
GlacialTech has introduced the IGLOO 5760 Multiple Platforms CPU cooler. This design incorporates a specially aligned copper heat pipe combination of three pipes that disperse the heat from the CPU directly into the heat sink fins. From there, the silent bullet axial fan quietly and efficiently brings the temperature down. The fan not only cools the radiator, but the added blow … [Read more...]
Researchers Cool Down Supercomputers with Warm Water
A team of IBM researchers in Switzerland is experimenting with a micro network of copper tubes that run through smaller, clustered computer servers and whisk away heat with the help of warm water. Liquid cooling, even with warm water, is 4,000 times more effective than air cooling at removing heat, they say. Researchers from IBM and the Swiss Federal Institute of Technology in … [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...]
