Cold plate helps lasers keep their cool

An Elite Thermal Engineering product story

Edited by the Engineeringtalk editorial team Oct 18, 2005

Elite Thermal Engineering has developed a new record-setting cold plate for laser diode cooling.

Elite Thermal Engineering, a thermal management company committed to providing high performance, economical yet compact photonics cooling solutions, announced the release of a new record-setting cold plate for laser diode cooling.

The cooling capacity of the cold plate model SCP-390 is 390W when the set temperature is equal to ambient temperature, and its footprint is only 283 x 210mm, thanks to ETE's proprietary DCS technology.

SCP-390 is 50% more powerful than the previous record of SCP-260 set by ETE in September 2005.

All the company's cold plates come with mounting patterns for most of the diodes they are intended to cool, and custom patterns are available on request.

SCP-390 was developed on the demand from the high power laser diode industry.

It is quickly gaining favour among high power laser manufactures and high power laser diode users.

SCP-390 is suitable for that high power laser diodes that dissipate more than 200W of highly concentrated heat.

Further custom enhancements could be made to SCP-390 to even further push up its performance for high ambient applications.

ETE's DCS technology is particularly crucial for cooling high power laser diodes such as those found in material processing lasers, medical research and high power fibre lasers.

Most of the high power laser diodes need to be cooled by liquid because of the limitation of conventional cold plates.

Chillers used for liquid cooling are heavy, expensive and less reliable comparing solid-state cooling systems.

It is also very hard to develop compact laser systems with liquid cooling.

DCS technology offers solutions for either direct cooling laser diodes with compact cold plates, or liquid cooling using ETE's discrete liquid cooling system which is also based on solid-state cooling with DCS technology.

Besides of standard cold plates, ETE is planning to offer custom packaged cold enclosures for medical, industrial and aerospace applications using the DCS technology.

The cold enclosures will have integrated thermoelectric coolers and heatsinks and cold plates, with optional environmental sealing.
