New research from MIT that identifies the key attribute in surface dissipation of heat could lead to improved power plant efficiency and better cooling of high-power electronics. A team of MIT researchers has reportedly completed what they claim is the first systematic investigation of the factors that control boiling heat transfer from a surface to a liquid, a process that is … [Read more...]
Thermal Conductivity of diamond-Ag Composites was Quoted at 983W/mK – Missing Something?
Editor’s note: This question was asked in response to Electronics Cooling’s recent webinar by Carl Zwebin. To view the webinar, click here. 1. Question: The thermal conductivity of diamond-Ag composites was quoted at 983W/mK. This was sure news to me. I was under the impression that an electrical insulator (diamond) was not compatible with an electrical conductor (Ag) in … [Read more...]

Discovery Could Change Textbook Models on Heat Transfer
A new discovery in the physics of heat transmission along nanowires could rewrite the models of heat transfer in current textbooks and bring major changes to the electronics industry. Researchers at the National Taiwan University’s Center for Condensed Matter reportedly found ballistic thermal conduction by phonons at room temperature along silicon-germanium nanowires. While … [Read more...]
Data Center Coolant Distribution System
Rittal Corporation, a manufacturer of industrial and IT enclosures, racks and accessories, has released a new coolant distribution system for use with Rittal’s rack- or door-mounted liquid cooling packages (LCP). Designed to handle all water routed between adjacent chillers and rack- or door-mounted LCPs, the new distribution unit is available with either four- and eight-tap … [Read more...]
