GrafTech Subsidiary AET Approved on Linux Networx Heat Sink Design.CLEVELAND -- Advanced Energy Technology (AET AET - Accelerated Environmental Test AET - Acoustic Emission Technique AET - Action Extreme Team (USA network show) AET - Actual Evapo-Transpiration AET - Actual Evapotranspiration AET - Advanced Extraction Technologies, Inc AET - Aeromedical Evacuation Technician AET - Aerospace Engineering Technician AET - Aerosurface End-to-end Test AET - Aetatis (Latin: Of Age) AET - Aetna, Inc.), a leading producer of electronic thermal management solutions under its eGRAF(R) brand name, has been approved for production on a new HS-400 Heat Sink A material that absorbs heat. Typically made of aluminum, heat sinks are widely used in amplifiers and other electronic devices that build up heat. Small heat sinks are the most economical method for cooling microprocessors and other chips. They are commonly found glued or clipped to the top or the side of the chip package. See heat pipe, CPU cooler and thermal grease. design in the next-generation LS/X supercomputer from Linux Networx. The complete thermal solution combines four eGRAF(R) HS-400 natural graphite heat sinks with two eGRAF(R) SPREADERSHIELD(TM) natural graphite pieces. AET's team of thermal engineers created a custom thermal solution for Linux, offering consultation services throughout the entire thermal design cycle. As a result of AET's intensive planning, testing and modeling process, Linux engineers discovered that the original total number of heat sink fins could be reduced, while maintaining performance and improving airflow in the system. AET also found that adding a SPREADERSHIELD(TM) heat spreader component would reduce the temperature of the power supply chip by 10 degrees C and maintain better long-term reliability. Overall, AET's HS-400 heat sink design significantly increased power by nearly 40% within the same form function (jargon) form function - The shape of something designed. This term is currently (Feb 1998) in vogue among marketroids.. Andy Reynolds, Lead Applications Engineer for AET, explained the key benefit of the new design. "The biggest advantage of our HS-400 Heat Sink over the traditional design is a weight savings of about 50%. With Linux's side-mounted design, an all-copper heat sink was just too heavy. Our lightweight solution improved mechanical shock and vibration performance and resolved issues with the mounting hardware." Dave Turner, Senior Mechanical Engineer for Linux, shares excitement for the new approach. "We have been very impressed with the high quality of innovative thermal engineering and design in AET products. Their expertise has been invaluable in overcoming our increased maximum power dissipation requirements within existing space limitations. Linux and AET have continued to work collaboratively to solve upcoming thermal challenges in next-generation products." About Advanced Energy Technology, Inc.
