TDK-EPC, a group company of TDK Corporation, has developed snap-in aluminum electrolytic capacitors from EPCOS that enable optimal contact to heat sinks. This permits link circuit capacitors to be efficiently cooled, significantly increasing their ripple current capability and operating life. As a result, the new capacitors are especially suited for applications in frequency … [Read more...]
Heat Pipe-Assisted Heat Sinks for Power Electronics Cooling
Advanced Cooling Technologies Inc. (ACT) in Lancaster, Pa., is introducing the heat-pipe-assisted HiK Plate heat sinks for power electronics cooling applications involving insulated gate bipolar transistors (IGBTs), thyristers, intelligent power modules (IPMs), symmetric gate commutated turn-off thyristors (SGCTs), and silicon controlled rectifiers (SCRs). Power electronic … [Read more...]
Beer Fridge – A Case Study in Thermal Design. Part 2 – TEC Effect
Beer drinkers are notoriously quiet people and as such would not want to be disturbed by the continuous hissing and whirring of a classic compression/expansion refrigeration cycle type beer fridge. They would argue that’s why both kids and kitchens were invented. Kitchens to put the noisy fridge in, kids to go get the next beer. Electric coolers, fridges that utilise … [Read more...]
TECs for Larger Heat Pumping Applications
Nextreme Thermal Solutions recently introduced the eTEC HV56 module, the next product in its high-voltage (HV) line of thin-film thermoelectric coolers (TECs) designed to address electronics cooling applications with larger heat pumping requirements. At 85°C, the eTEC 0.6mm-high HV56 can pump 6 watts or 58 W/cm2 of heat in footprint of only 11 mm2. At 85°C, the eTEC HV56 can … [Read more...]
IMS Research Estimates LED Market Shares for 2009 and 2010
In a new report updating market shares for 2009 and provisional market share for 2010, IMS Research says 2010 was a year of tremendous growth in the LED industry, dramatically higher than the typical growth rates of recent years. The researchers estimate the market for LEDs has grown from $6.1 billion in 2009 to about $10 billion in 2010, driven by economic recovery, lighting … [Read more...]
