Laird Thermal Systems™ Premium Thermoelectric Coolers Provide Temperature Stability for Outdoor Security Cameras
The new HiTemp ETX Series of thermoelectric coolers keep imaging sensors cool in high temperature environments…
October 27, 2020 – Imaging sensors and other
sensitive camera components such as FPGA require active cooling to
keep operating temperatures below their maximum limit, ensuring
high-quality image resolution. Due to solar radiation and increased heat
flux density from surrounding electronics, outdoor security cameras can
reach temperatures up to 90°C. This may cause performance degradation,
loss of image resolution or even system failure. Laird Thermal Systems™
new HiTemp ETX Series can survive in temperatures up to 150°C, making
them ideal for spot cooling in outdoor security camera applications.
Designers of outdoor security cameras not only face challenges such
as harsh environments and system temperature fluctuations, but they are also asked to pack a growing number of features into smaller form factors,
resulting in higher internal heat loads in the camera. A lack of airflow
due to completely sealed compartments 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 requiring cooling. Because standard thermoelectric coolers were not designed for high temperature environments, Laird Thermal Systems developed a new generation of thermoelectric coolers to improve reliability and cooling performance. The new HiTemp ETX Series has a robust construction and is assembled with advanced thermoelectric materials that boosts cooling capacity by up to 10%. It also features a higher insulating barrier compared to 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.”
The HiTemp ETX Series is available in more than 50 models to cover the wide range of emerging applications and support unique footprint requirements, cooling capacity needs, voltage inputs and finishing options.
