Peltier devices handle large thermal loads
Addressing the thermal noise that causes CMOS sensors, lasers and other sensitive devices to lose image resolution as temperatures rise, Laird Thermal Systems expanded its Peltier product family with the HiTemp ET Series of thermoelectric modules (TEMs). These modules are designed using Laird’s enhanced TEM construction to prevent performance degradation and copper diffusion, common in standard TEMs used at high temperatures.
The thermoelectric modules are suited for use in automotive, machine vision and learning and high-end scientific cameras and for higher current and larger heat-pumping applications, where they provide precise temperature control accuracy achieving ±0.01°C. They offer active cooling in temperatures ranging from 80°C to 150°C.
The series maintains a high coefficient of performance, enabling maximum heat removal in the air. The environmentally-friendly modules provide a cooling capacity of more than 300 watts; are housed in a compact form factor; eliminate sound and vibration and are RoHS compliant.
