Heat Sinks Cool DC-DC Converters in Low Airflow Conditions

norwood, ma, october 2005 – advanced thermal solutions, inc. (ats) has introduced a line of low profile, high performance heat sinks designed to optimize the thermal management of pcb-mounted power modules in spatially-constrained applications where airflow is limited. the new powerice™ heat sinks allow circuit designers to achieve higher pcb performance levels than available from conventional over-sized heat sinks. compact powerice™ heat sinks are ideal for bypassed and unducted flow conditions because their smaller size 58 x 61 mm (l x w) increases space to improve airflow. their lighter weight aluminum fins and base reduce costs by eliminating supplemental mechanical mounting clips.

all powerice™ heat sinks feature a patented design that outperforms conventional heat sinks in comparable applications. they eliminate excessive resistance to heat spreading that is common with over-sized heat sinks. thermal resistance is as low as 1.23c/w with air velocity of 600 ft/min.

powerice™ heat sinks are designed in low profile sizes from 4 to 7 mm (h). weight range of the sinks is 4 to 30 grams. they are provided with a high strength double-sided thermally conductive adhesive tape for quick assembly without fasteners.

pricing for powerice™ heat sinks starts as low as under $5.00 for some models at high quantities. more information on powerice™ sinks can be found on the advanced thermal solutions website, www.qats.com, or by calling 781-769-2800.

advanced thermal solutions is a leading engineering and manufacturing company supplying complete thermal and mechanical packaging solutions from analysis and testing to final production. ats provides a wide range of heat sinks and laboratory-grade thermal instrumentation, along with thermal design consulting services and training.
