High temperature is the enemy of integrated circuits. It will not only lead to unstable operation of equipment, shorten service life, and even cause equipment parts to be burned. If it is portable electronic equipment, it will also cause harm to the human body. The heat that causes the high temperature comes from inside the electronics, or integrated circuits. The function of the heat dissipation component is to absorb the heat and disperse it into or out of the equipment to ensure the normal temperature of the electronic components.

Road traffic in the face of today's complex, racketeer player available situation, 4 g vehicle traveling data recorder has become a smart product owner video record traffic, especially now many recorder are equipped with a 1080 p h d video recording, video vehicle traveling data recorder when the job is running continuously, the main device is a large amount of data processing, the high-speed operation of the chip, The resulting heat is also very large. Without heat treatment for key components, the recorder will stop recording, restart, or even burn.

In particular, many driving data recorders are hung on the front windshield and exposed to sunlight. After a long time, they will be "dead" in the sun. As soon as they are turned on, they will become hot and die. How to do when the vehicle data recorder heats up and dies? It is necessary to solve the problem of heat dissipation of the recorder in the product design, and the application of thermal silicone sheet is the mainstream solution at present. You may think that there is no problem if I buy a sun proof and high temperature resistant vehicle recorder. The key is to take appropriate medicine to the case. The most fundamental thing is to start from the internal heat dissipation structure of the vehicle recorder and choose a suitable thermal silicone sheet to solve the problem of heat dissipation of the heat source.

The main role of thermal silicone pad is to transfer heat to the main devices for cooling, to ensure the normal operation of 4G vehicle recorder heat dissipation. The cooling principle of the thermal silicone pad is to conduct the heat from the DSP master chip and DDR2 chip of the driving data recorder to the shield cover, and then radiate the heat to the air and the ground of the main board through the shield cover to conduct heat dissipation.
