Design engineers continued to see new products aimed at facilitating heat dissipation, a particular concern as electronic devices are put into more compact packages while pushing more power. Announced at the show was Raychem's low-thermal-resistance HeatPath(TM) gel family. The conformable gel easily fills gaps between components and heat sinks with minimal pressure applied, thus avoiding damage to delicate parts. Eliminated are clamping systems and tight tolerance control ...Also debuting was the DC 2406KL series of fans from NMB Technologies. These light (45 g), small (60 X 60 X 15 mm) fans produce only 19 to 34 dB of noise. Preloaded, shielded ball bearings and variable speed control via a separate heat sensor increase fan lifetime.
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.
