Advanced Thermal Solutions (www.qats.com) has introduced the blackDIAMOND heat sink designed for passive cooling of Intel Xeon. Made from solid anodized aluminum and void of the interfacial thermal resistances in bonded heat sinks, blackDIAMOND measures at 30 mm high by 64 mm wide by 89 mm long for CPUs used in 1U packages, including the Intel P4, and the AMD Opteron and Athlon 64. The sink weighs from 144 to 162 gm, and provides thermal resistance as low as 0.28 C/W with air velocity of 800 ft/min.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
