1. Heat dissipation design and temperature control
Fanless embedded industrial computers use special heat dissipation design to ensure long-term operation reliability. Its heat dissipation method mainly relies on heat sinks and thermal conductive materials. By using a large area heat sink, the contact area with the air is increased, thereby improving the heat dissipation efficiency. For example, aluminum alloy heat sinks are used, which have good thermal conductivity. At the same time, high-efficiency thermal conductive silicone grease is used between the chip and the heat sink to quickly conduct heat away. In addition, the shell of the industrial computer also participates in the heat dissipation process, and its special material and structure help to dissipate heat. Through precise thermal design, the internal temperature of the industrial computer is always kept within the normal operating temperature range of each hardware component during long-term operation, avoiding hardware damage caused by overheating, thereby ensuring the reliability of the hardware.
2. Selection and quality control of hardware components
In the selection of hardware components, fanless embedded industrial computers select high-quality, industrial-grade components. For key components such as processors, memory, chipsets, etc., products that have been strictly tested and have high stability and durability are selected. For example, processors will choose models that are designed for industrial environments and can work normally in a wide temperature range (such as - 40°C to 85°C). In terms of memory, memory with error correction function (ECC) is used, which can automatically detect and correct data errors in the memory. Moreover, during the production process, each hardware component is strictly tested for quality, including aging test, high temperature and high humidity test, etc., to ensure that only qualified components are used for the assembly of industrial computers, and the reliability of hardware is guaranteed from the source.
3. Redundant design and protection mechanism
In order to cope with hardware failures that may occur during long-term operation, fanless embedded industrial computers adopt redundant design and multiple protection mechanisms. In terms of power supply, redundant power supply modules may be used. When one power supply fails, the other power supply can continue to provide stable power supply for the industrial computer. In the hardware circuit, over-temperature protection, over-voltage protection, over-current protection and other circuits are set. For example, when a chip is detected to be too hot, the over-temperature protection circuit will automatically reduce the chip's operating frequency or take other heat dissipation measures; when the voltage or current exceeds the normal range, the corresponding protection circuit will cut off the circuit to prevent the hardware from being damaged by abnormal voltage or current. These designs greatly improve the reliability of the hardware.
4. Anti-vibration and anti-interference design
In industrial environments, fanless embedded industrial computers may be subject to vibration and electromagnetic interference. In terms of anti-vibration design, a sturdy shell structure and internal fixtures are used to firmly fix each hardware component inside the industrial computer to prevent problems such as loose components and desoldering caused by vibration. For anti-electromagnetic interference, the shell of the industrial computer uses shielding materials, which can effectively block external electromagnetic interference; at the same time, in circuit design, filtering circuits, isolation circuits and other technologies are used to suppress the electromagnetic interference generated by the internal circuit, ensuring that each hardware component can operate stably in a complex electromagnetic environment, thereby ensuring the reliability of the hardware for long-term operation.
