Rittal Corporation, a manufacturer of industrial enclosures, server racks, power distribution systems and data center cooling products, has released the Liquid Cooling Package Direct Expansion (LCP DX) cooling option. According to the company, the LCP DX is flexible, easily installable and ideal for small and medium-sized installations where climate control with air/water heat … [Read more...]
Researchers Demonstrate Thermal Invisibility Cloak with Potential for More Effective Heat Management
In recent years, scientists have developed the ability to manipulate light around an object through the use of man-made “metamaterials,” rendering the object seemingly invisible. Now, researchers from the Karlsruhe Institute of Technology (KIT) in Germany have demonstrated the similar ability to manipulate the flow of heat across a sheet of metal to hide a defect in the … [Read more...]
Why Not Just Shove a Heatsink on Top of it? Part 1
A common enough question. Heatsinks are often perceived to be the magic answer to all electronics cooling challenges. They should be called ‘area extenders’ as heat does not just disappear into them. Heat spreads throughout a heatsink passing to the air over a much larger area than it would otherwise do. Air can then do its magic, whisking the heat away thus keeping … [Read more...]
New Method Combines Gallium Nitride and Diamond for Better Thermal Management of Amplifiers
A demonstration of what is considered to be the first-ever gallium nitride (GaN)-on-diamond high electron mobility transistor could significantly reduce thermal resistance and increase RF performance in monolithic microwave integrated circuit (MMIC) power amplifiers, DARPA said in a statement. While MMIC power amplifiers equipped with gallium nitride transistors hold the … [Read more...]
Astronauts Fix Ammonia Coolant Leak on International Space Station
UPDATE May 13, 2013: Expedition 35 Flight Engineers Chris Cassidy and Tom Marshburn completed a five-hour spacewalk on Saturday to replace a pump controller box on the International Space Station’s far port truss, NASA officials reported Sunday. Long-term monitoring of the replacement pump will be required to determine whether the issue has been fixed. May 10, 2013: Astronauts … [Read more...]
