Laird Thermal Systems has rolled out a new thermoelectric module series that is rated for high-temperature optoelectronic applications. The HiTemp ETX Series thermoelectric coolers can operate in temperatures up to 150°C, exceeding most outdoor applications. In addition, thanks to advanced thermoelectric materials, the coolers offer increased cooling capacity by up to 10% compared to traditional thermoelectric coolers, said the company.
Targeting highly sensitive optoelectronics, particularly those designed into outdoor environments that need active cooling to keep below their maximum operating temperature, these new coolers combine the enhanced thermoelectric materials with a proprietary construction that prevents performance degradation in high temperature environments, often cited as a common problem with standard-grade thermoelectric coolers.
Common applications for optoelectronic devices include LiDAR and CMOS sensors for autonomous systems in vehicles and drones, digital light processors (DLP) used in 3D machine vision and advanced lighting systems, and optical transceivers.

These thermoelectric modules or solid-state heat pumps deliver a high coefficient of performance (COP), which minimize the amount of input power needed to operate and reduce the heat rejection requirement to the hot side, which is critical in poor heat sinking applications, said the company. They also provide a higher thermal insulating barrier when compared to standard thermoelectric materials creating a maximum temperature differential (Delta T) of up to 83°C.
The HiTemp ETX Series is available in over 50 models with a variety of footprints, cooling capacities, voltage ranges, and finishing options. Visit here to check for stocking distributors.
