Thermoelectric coolers deliver precise spot-cooling for industrial lasers

16-02-2021 | Laird | Subs & Systems

The new UltraTEC UTX Series thermoelectric cooler from Laird Thermal Systems produces precise spot cooling to preserve peak performance of lasers and optoelectronics. Due to its solid-state operation, the series gives low maintenance and long-life operation. Through advanced breakthroughs in materials sciences, the series provides a 10% boost in heat pumping capacity and a higher COP across standard grade thermoelectric materials.

Constructed with advanced thermoelectric materials, the series provides a heat-pumping capacity up to 296W. The proprietary module construction provides a higher thermal insulating barrier than standard thermoelectric coolers, obtaining a maximum temperature differential (?T) of 72C. A thermoelectric cooler can be mounted straight onto the laser diode for temperature stabilisation. For higher heat loads, the ambient liquid cooling system can use multiple thermoelectric coolers in an array.

"Given that the heat rejection path for passive cooling of these devices still elevates its temperature, a method of active spot cooling will be required to keep the lasers cool while the surrounding environment is hot," said Andrew Dereka, product director at Laird Thermal Systems. "Our enhanced UltraTEC UTX Series is ideal for spot cooling of industrial laser applications that require high heat pumping capacity in a small area."

The series is offered in various footprints, capacities, configurations and voltage inputs.
