A large number of optical, electronic and mechanical components are integrated inside the automotive radar, which is an optoelectronic integrated sensing device with high integration and high power density. As the "eyes" of unmanned driving, the component density and power density of automotive radar are also increasing. Correspondingly, it's internal electronic components put forward higher requirements for more heat dissipation. For automotive radar, temperature is the most important cause of failure.

With the rise of the application of automotive radar in autonomous driving, more and more environmental data needs to be processed by automotive radar, and the heat consumption generated is also increasing. The vehicle-mounted laser radar mainly includes three parts: the main control power supply module, the motor installation module and the rotating prism module. During the working process, the rotating prism module is located in the motor installation module and rotates with the help of the motor to transmit and receive laser signals. Since the vehicle-mounted automotive radar requires the protection level of ip67 or even ip69, the main control power supply module is equipped with a heating device, and in a closed environment, it is almost impossible to use active cooling methods such as "fans".

Thermally conductive materials also play an important role in automotive radar. Automotive radar usually needs to work in a high temperature and high humidity environment, which leads to an increase in the internal temperature of the automotive radar. If it cannot be dissipated in time, it will affect the performance and life of the automotive radar.

Thermally conductive interface materials can help automotive radar dissipate heat, which improves the stability and lifespan of the equipment. Commonly used thermally conductive interface materials include thermal adhesive, thermal silicone grease, thermal pads. These materials have excellent thermal conductivity and can effectively transfer heat away from the automotive radar device to the surrounding environment, preventing overheating and damage to the equipment. Proper selection and application of thermally conductive interface materials can significantly enhance the thermal management of automotive radar systems.
