Thermal solution for driving recorder

Thermal solution for driving recorder

High temperature is the enemy of integrated circuits, which will not only lead to unstable operation of the equipment, shorten the service life, and even cause the burning of equipment components. If it is a portable electronic device, it will also cause harm to the human body. The heat that causes the high temperature comes from inside the electronic device, or inside the integrated circuit. The function of the heat dissipation component is to absorb the heat and dissipate it into the device or outside the device to ensure that the temperature of the electronic components is normal.

Faced with the complex traffic conditions today, the 4G driving recorder has become a smart product for car owners to record driving video, especially now many recorders are equipped with 1080P ultra-high-definition video recording, driving when working. The recorder is constantly recording video, the amount of data processed by the main device is very large, the chip is in a high-speed operation state, and the heat generated is also very large. If the key components are not cooled, the recorder will stop recording, restart, or even burn out.

In particular, many driving recorders are hung on the front windshield and exposed to the sun. After a long time, they will be “dead” from the sun, and they will become hot and dead as soon as they are turned on. What should I do if the driving recorder overheats and freezes? Then it is necessary to solve the problem of heat dissipation of the recorder in the product design scheme, and the application of thermally conductive silicone sheet is the current mainstream scheme. You may think that it is no problem for me to buy a sun-resistant and high-temperature-resistant driving recorder. The key is to find the right medicine. The most fundamental thing is to start with the heat dissipation structure inside the driving recorder and choose a suitable thermal conductive silicone The chip is used to solve the problem of heat dissipation of the heat source.

The main function of the thermally conductive silicone sheet is to conduct heat to the main components for cooling, and to dissipate heat for the 4G driving recorder to ensure normal operation. The cooling principle of the thermally conductive silicone sheet is to conduct the heat of the DSP main control chip and the DDR2 chip of the driving recorder to the shielding cover, and then radiate the heat to the air through the shielding cover and conduct heat dissipation to the ground layer of the motherboard.

Thermally conductive silicone sheet is the core product with the highest sales in Cohetion’s main thermal interface materials. The thermal conductivity is available from 1.0 to 10.0W. When choosing a thermally conductive silicone sheet for 4G driving recorders, you only need to choose Novotel The NF150 thermal conductive silicone sheet with a thermal conductivity of 1.5W/Mk can meet the heat dissipation requirements. LC150 is a hot-selling thermally conductive material product independently developed by Nuofeng Electronics, with a high market share. The production raw materials are imported raw materials, and the production and quality are strictly controlled throughout the process. All products adopt the international thermal conductivity test standard ASTM D5470, and the quality is guaranteed.
