Thermoelectric modules,peltier devices,peltier modules,thermoelectric cooling modules are applied in automotive lidar applications, featuring high temperature control accuracy and large cooling power. With the large-scale commercial deployment of 5G, autonomous driving is one of the future development trends and important application scenarios of 5G. High-performance LiDAR is a core component for achieving autonomous driving and needs to be actively cooled to work effectively and reliably. TEC module, thermoelectric cooling module, thermoelectric temperature control technology can achieve high-precision wavelength control and stable power for high-power lasers of LiDAR. Meanwhile, precise temperature control of sensors such as APD/SPAD can enhance sensitivity and signal-to-noise ratio, expand the working temperature range, increase detection distance, resolution, anti-interference ability and reliability.
Optical devices with peltier modules, thermoelectric modules, TEC modules are crucial for achieving a detection range of over 200 meters and high-performance autonomous driving applications at L3 level and above. Compared with optical communication applications, the requirements for TEC, thermoelectric cooling products themselves in automotive lidar are slightly different, including more precise temperature control, higher cooling power, a wider operating temperature range, greater temperature difference performance, and reliability in extreme environments.
In the application of the automotive field, achieving high reliability without sacrificing performance is extremely important. The differentiated advanced thermoelectric cooling module,thermoelectric module, peltier cooler, TEC design and manufacturing methods enable Beijing Huimao Cooling Equipment Co.,Ltd. to meet these two requirements without sacrificing performance. In the field of lidar, Beijing Huimao Cooling Equipment Co.,Ltd. has launched the TES1-02902TT200 TEC module, thermoelectric module, with a size of 6*10.2*2mm. Size is an important selection factor. This kind of small-sized TEC module has high technical requirements. There are not many manufacturers that can produce small-sized TEC modules, thermoelectric cooling modules, miniature peltier modules. Beijing Huimao Cooling Equipment Co.,Ltd. has been working in the automotive and optical communication markets for many years and has a lot of experience in the research and development, design and mass production of small size Micro TEC modules, peltier modules, miniature thermoelectric cooling modules.
The product quality, reliability and performance of TEC module of Beijing Huimao Cooling Equipment Co.,Ltd. are integrated into all products and processes from beginning to end. Combined with TEC controllers and temperature sensors, etc., it is completely fine to control the temperature uniformity accuracy within ±0.1℃. The TES1-02902TT200 model has a metallized surface and can be soldered together with the device to achieve excellent heat transfer performance. When the hot end temperature Th=30℃, the maximum power can reach 4W. When the hot end temperature Th=80℃, the maximum power can reach 6W. Within a limited area, it has a very high cooling power, which can ensure the rapid cooling of the laser. Its maximum process temperature reaches 223℃, and the maximum temperature difference can reach 71℃. It has high reliability and is very suitable for the application of vehicle-mounted lidar.
