Thermoelectric modules protect heat sensitive CMOS sensors

07-05-2019 | Laird | Test & Measurement

Laird Thermal Systems has expanded its Peltier thermoelectric module product family with the HiTemp ET Series, created to protect critical electronic devices like CMOS sensors in high-temperature applications. Advances in CMOS sensor technology has made these sensors efficient and practical for use in a broad variety of imaging applications seen in autonomous systems, high-end scientific cameras, machine vision and learning, and more.


This series of thermoelectric modules perform spot cooling to assure optimum CMOS sensor performance. The series is a preferred cooling solution in CMOS sensor uses and has shown not to degrade in high heat environments. To satisfy a broad range of design demands, the series includes 53 models providing a diversity of heat pumping capacities, geometric form factors and input voltages.


"As CMOS sensors are incorporated into new emerging applications for outdoor environments, thermal management becomes more important to keep sensors below their maximum operating temperature limit," said Andrew Dereka, product director at Laird Thermal Systems. "Spot cooling that features a thermoelectric module provides an active cooling solution that allows these critical sensors to maintain maximum image resolution for their application."


Providing active cooling for applications performing in temperatures ranging from 80C to 150C, the series gives a cooling capacity of more than 300W in a compact form factor. The series is intended for higher current and larger heat-pumping applications allowing precise temperature control accuracy achieving ┬▒0.01C.
