Thermoelectric modules will not degrade, assures Laird

Thermoelectric module (TEM) products from Laird protect critical electronic devices in emerging applications found in high temperature environments. While this typically occurs in outdoor environments where heat generated from surrounding electronics exceeds the temperature of sensitive electronics with maximum operating temperatures of 60 to 70 degree C, the company has introduced the HiTemp ET series which delivers spot cooling to ensure maximum temperature of device is not exceeded in ambient environments greater than its maximum operating temperature.

The HiTemp ET series includes 53 models with a wide range of heat pumping capacities, geometric form factors and input voltages to cover a range of applications.

Laird explains that its enhanced TEM construction prevents copper diffusion, which commonly occurs for standard grade TEMs in higher temperature environments and prevents degradation in their performance. The HiTemp construction does not sacrifice performance for reliability but maintains a high co-efficient of performance (COP) to allow for maximum heat rejection into air environment even with poor heat sinking.

Many sensitive devices, such as lasers and CMOS sensors, are designed into autonomous systems for collision avoidance in vehicles and drones. Digital light processors (DLP) are used in 3D machine vision, advanced lighting systems and projectors that may also require cooling in outdoor environments where ambient temperatures exceed its maximum operating temperature condition.

Laird Thermal Systems offers continuous access to OEMs through its component and application expertise. Laird is a global technology company focused on providing systems, components and solutions that protect electronics from electromagnetic interference and heat, and that enable connectivity in mission critical systems through wireless applications and antenna systems.
