Cooling Solutions for Autonomous Systems


Advances in autonomous technologies, such as smart headlights, autonomous systems for collision avoidance, and infotainment systems, require enhanced thermal protection of critical electronics to ensure optimized performance. These emerging intelligent autonomous systems are increasingly complex while decreasing in size and weight. Packing more functionality into smaller footprints has increased the heat flux density and thermal challenges in autonomous systems.





New High-Temperature Thermoelectric Coolers from Laird Thermal Systems Cool Optical Sensors in Advanced Driver-Assistance Systems (ADAS)


Advanced driver-assistance systems (ADAS) use a variety of imaging sensors, cameras and lasers to enhance vehicle safety and create better driving conditions. Most of these optical devices, including CMOS sensors and laser diodes, are heat sensitive and rely on high-resolution images for proper operation. Image quality can quickly deteriorate as the device temperatures rise above 60°C.
