Temperature problems and measures faced by embedded motherboard

As friends who have used industrial control computers know, many embedded industrial control mainboards will be used in very bad conditions, such as permanent startup within the service life, bad weather, humidity, vibration, dust, radiation, high temperature, etc.

The main feature of the industrial control motherboard that can be used in industrial production is that it can work stably and faultlessly in the environment between - 20 ℃ and 60 ℃, and even some industrial motherboards adopt special wide temperature design, with the temperature range of - 20 ℃ to 70 ℃. This is a severe test for the mechanism's cooling scheme and cooling efficiency.

In terms of the heat dissipation design of the industrial control main board mechanism, Zechuang Weiye uses the special heat dissipation design, even uses the all-aluminum mechanism shell, and carries out special treatment for the CPU, the North-South Bridge and the hard disk and other large heat users to ensure the normal operation of the industrial control main board and the whole machine.

Relatively speaking, commercial motherboards are not competent in these environments and can only operate in a stable environment. The commercial motherboard can only be used in the ambient temperature between 5 ℃ and 38 ℃. It has low requirements for the heat dissipation of the mechanism, and pays attention to its cool and cool appearance.

Many industrial personal computers are used in harsh application environments (such as damp, vibration, dust, radiation, high temperature, etc.). The dust and salt in the air will cause corrosion to the main board and affect the normal use of the main board.

In our work and life, many people will come into contact with commercial motherboards and industrial control motherboards. We should know exactly that it is necessary for many industrial PCs to adopt fanless chassis structure to prevent the system from being damaged by harsh environment. However, due to the mutual interference of heat sources, the fully sealed fanless structure has high requirements on the performance and stability of the main board.

Through special design, the industrial control motherboard can realize the functions of automatic restart of the watchdog and anti-surge impact in case of abnormal conditions such as crash, and fully guarantee the requirements of high stability of the system in harsh environment.

In addition, you can also replace fans with better cooling performance. Check whether the thermal silica gel is invalid. If it fails, replace the thermal silica gel again. Clean the dust inside the cabinet and arrange the wiring, which will affect the heat dissipation.
