Laird Thermal Systems has launched its new HiTemp ETX Series, which can be used in applications that have temperatures up to 150°C.

This makes the cooler ideal for applications that require spot cooling, such as outdoor security camera applications. The designers of outdoor security cameras face challenges such as harsh environments and system temperature fluctuations.

They are also asked to include a growing number of features into smaller areas, which results in higher internal heat loads in the camera. These devices often have a lack of airflow due to being situated in completely sealed enclosures, which makes it even more difficult to dissipate heat away from temperature-sensitive electronics such as imaging sensors.

Thermoelectric coolers are solid-state devices that use the Peltier effect to actively pump heat away from electronic devices. Standard thermoelectric coolers are not designed for high temperature environments. Laird Thermal Systems has designed this new generation of thermoelectric coolers to improve reliability and cooling performance.

The company’s new HiTemp ETX Series has been designed with a robust construction and has been assembled using advanced thermoelectric materials that boosts cooling capacity by up to 10%. The coolers also have a higher insulating barrier than standard thermoelectric coolers, achieving a temperature differential ( ΔT) of up to 83°C.

"The HiTemp ETX Series is our latest thermoelectric product offering that is specifically designed for emerging spot cooling applications in high temperature environments," said Andrew Dereka, Product Director at Laird Thermal Systems. "This product series uses the latest thermoelectric materials and robust construction to assure long life operation in many critical applications such as imaging in outdoor environments."

There are more than 50 models in the new HiTemp ETX Series. The variants are intended to cover the wide range of emerging applications and support unique footprint requirements, cooling capacity needs, voltage inputs and finishing options.
