Nextreme claims breakthrough cooling performance

LONDON — Nextreme Thermal Solutions Inc. (Durham, North Carolina), a maker of thermal management products, has claimed that it's OptoCooler HV14 product has produced a 60 degree C temperature difference between its cold and hot sides.

For customers in the optoelectronics and telecommunications industries, this translates to improved cooling performance, lower input power requirements and greater efficiencies for solving thermal management issues in electronic packages.

The OptoCooler HV14 was introduced in January 2009 with a specificed temperature difference of 51 degrees C. The improved performance is the result of recent advances in thin-film technology at Nextreme, the company said.

The device can pump up to 1.5 watts of heat at 85 degrees C and operates at a maximum voltage of 2.7-V with a maximum current of around 1A; with a footprint of only 2.8 square millimeters. The module is suitable for the cooling and temperature control of optoelectronic devices such as laser diodes for transmission modules and photodiodes for sensing.

"Breaking the 60°C ΔT barrier raises the bar in terms of improved efficiencies and lower operating costs," said Dave Koester, vice president of engineering at Nextreme, in a statement.
