Laird Thermal Systems rolled out a new series of Peltier cooler modules that can provide active spot cooling for smart digital light processing (DLP) automotive headlights, and other sensitive electronics such as lasers, CMOS sensors, and LiDAR. The cooler offers several benefits including long life operation, a small form factor to fit into tight spaces, and no outgassing, which eliminates the coating buildup on lens surfaces that often occurs over time.
Automotive headlight systems often operate in high-temperature environments and can reach 110°C; however, the operating temperature of a DLP is 70°C, said Laird. The new HiTemp ET series of thermoelectric cooler modules can provide the spot cooling required for these types of environments.
These Peltier coolers can lower the control temperature by as much as 40°C below ambient, depending on active heat load. They offer a cooling capacity of more than 300 watts.
The HiTemp ET Series operates over a temperature range of 80°C to 150°C. The series offers 53 models to meet a wide range of applications, such as heat-pumping requirements, geometric form factors, and input power to cover DLP design requirements.
