Lytron's High Performance Cold Plate Wins R&D 100 Award

CP25 Copper Cold Plate

Woburn, MA, 10 August 2004. Lytron's  high performance cold plateTMAscent has won an R&D 100 Award from R&D Magazine. This award recognizes the Ascent as "one of the 100 most technologically significant products introduced to the marketplace over the past year", as selected by R&D magazine's independent judging panel and editors.

The Ascent is an all-copper, ultra-low thermal resistance, water compatible cold plate designed for contact cooling of high watt-density electronic components such as IGBTs, MOSFETs, resistors, diodes, etc. It offers significantly higher performance than other cold plate technologies at a volume production price that is in line with lower performance cold plate technologies.

The Ascent's normalized thermal resistance at 1gpm (3.8 lpm) is 0.058°C in2/W. This is 60% better than the equivalent aluminum part and ten times better than a standard tubed cold plate. This is achieved through the use of a thin mounting surface and an internal criss-cross fin structure, which improves thermal mixing. The Ascent is constructed entirely of copper, which makes it compatible with untreated water as well as many other common coolants.

The standard Ascent's mounting surface is 2 ½ inch (63.5mm) long by 1 5/16 inch (33.3mm) wide. The length can easily be modified for custom applications. Furthermore, the technology can be integrated into a larger cold plate for cooling larger areas, for example board cooling applications.

Ascent cold plates are used in applications such as power supplies, lasers, RF transmitters, semiconductor processing equipment, traction and variable frequency drives, and uninterruptible power supplies.

"This award is a reflection of Lytron's strong engineering foundation and continued commitment to new product development," says Charlie Carswell, Lytron's President. "To maintain Lytron's leadership in liquid contact cooling, we continually develop new and better cold plate technologies. Lytron now offers 5 unique cold plate technologies - more than anyone else in the industry. This broad product offering provides our customers with the best technology for their cooling requirements."
