Several weeks after NASA aborted a spacewalk outside the International Space Station following a report of a water leak inside Italian astronaut Luca Parmitano’s helmet, Parmitano’s spacewalk partner has released a two-part video explaining the origin of the leak. The July 16 spacewalk was aborted approximately an hour-and-a-half into what was to be a six-hour spacewalk to … [Read more...]
High Temperature Capacitors Could Remove Need for EV Cooling Systems
A new lead-free, high temperature ceramic capacitor developed by scientists at the National Physical Laboratory (NPL), UK could improve the efficiency and reliability of electric and hybrid vehicles by enabling the removal of heavy complex cooling systems. “Electric vehicle operating temperatures can go up to 140°C [almost double the temperature conventional capacitors can … [Read more...]
Thermal Adhesive Tape for Application to Unprocessed PCBs
Thermal management materials manufacturer Universal Science has introduced a new thermal adhesive tape designed to be applied to FR4 or insulated metal substrate printed circuit boards (PCBs) prior to processing as a replacement for mechanical fixings. Featuring a thermal conductivity of 2.0 W/mK and a breakdown voltage (electrical isolation) of 4 kV AC, Bondline 2000-REFLOW … [Read more...]
New Fans Simplify Data Center Cooling Retrofits
Rosenberg USA, a manufacturer of fans and blowers for a variety of applications, has released new UNOBOX fans designed to simplify data center cooling retrofits in under-floor and in-cabinet applications. “The Rosenberg UNOBOX extract fan consists of a high-efficiency backward-curved motorized impeller with an electronically commutated motor mounted inside a cube-shaped … [Read more...]
Researchers Test Cooling System in Zero-Gravity
University of Illinois at Chicago researchers have completed high- and zero-gravity testing of an evaporative cooling system developed for sophisticated microelectronic systems onboard an astronaut training aircraft following three years of preparation supported by NASA. Managed by CNES subsidiary Novespace since 1997, the Airbus A300—nicknamed the Zero-G—is a short- to … [Read more...]
