Reasons for heat resistance of industrial grade switches

1. Industrial grade components

Industrial-grade switches are different from commercial switches. They usually operate for a long time once they are started, and the natural environment in which they operate is often extreme. Wind, sand, insects, and humidity will directly affect the operation of the fan. The impact of excessive temperature on industrial-grade switches is fatal. Therefore, when designing, all equipment components need to select industrial-grade components with a wide temperature range. The long-term stable operation in this temperature range makes the equipment not afraid of extreme environments.

2. Chassis cooling system

Generally speaking, there are two types of cooling designs for switches. Front air inlet, rear air outlet type and left air inlet, right air outlet type. These heat dissipation designs are the same, but due to the difference in the overall design, different types of heat dissipation wind directions are produced. There are also some strange designs on the market at present. Obviously, it is the front air intake type and the rear air outlet type, but the fan is installed on the side. This design is obviously unscientific and greatly shortens the service life of the switch.

3. Thermally conductive silicone sheet

The thermally conductive silicone sheet is mainly used for heat conduction and heat dissipation between the motherboard and the shell. The main purpose of selecting thermal silica gel sheet is to reduce the contact thermal resistance formed between the surface layer of the heat source and the contact surface of the heat dissipation device. The thermal silica gel sheet can well fill the gap between the contact surfaces; with the supplement of thermal silica gel sheet, the heat source can be The contact surface between the radiator and the radiator is better enough to touch, and the real touch is face-to-face, and the temperature response can reach the smallest possible temperature difference; the heat-conducting silicone sheet not only has insulation performance, but also has the effect of shock absorption and sound absorption .

4. CPU heat sink

The design of heat-conducting silicone sheet + CPU heat sink + 4 fans is selected, the heat dissipation speed is faster, and the heat dissipation effect is still stable after long-term use. When the CPU is working, it also generates a lot of heat. Due to its limited surface area, it cannot release heat in time. We can help it expand the heat dissipation area by connecting it with a heat sink. You can see that the radiator is basically composed of many fins, which is a design to increase the heat dissipation area. When the heat of the CPU is conducted to the radiator, it will quickly spread to the surface of all the fins; the fan blows air on the fins of the radiator, and the wind can take away the heat.

5. High-strength metal strong heat dissipation

Adopt fanless mute design - wide temperature and wide pressure design, aluminum alloy metal shell with super heat dissipation, quiet and no noise in normal operation, and avoid the adverse effects of dust on the internal structure of the machine. Ideal for environments where silence is required! It is the most popular cooling method at this stage! For example, Houshi industrial switches all use high-strength aluminum alloy shells for natural heat dissipation, and the upper two sides use corrugated design, which greatly increases the heat dissipation area of ​​the equipment. The shell has passed the IP40 protection level, which reduces the impact of sand, dust, insects, and humidity on the normal operation of the equipment. .

In addition, we learned that when designing industrial switches, in addition to selecting industrial-grade components with a wide temperature range and a corrugated high-strength body, they must also undergo high and low temperature tests. , each industrial switch is stable and reliable in harsh environments, ensuring the stable transmission of industrial communications. The above is the secret that industrial switches can withstand high temperature and stable operation.
