The cabinet is dust-proof, so there is no cabinet brush_FAQ

In our daily life, sunshine and air are an indispensable part, and then there is another thing that often surrounds us, which has always brought us troubles and even harm. It is dust. Dust likes electronic products very much. Those who have cleaned home and office electronic equipment should know how great the hazards of dust are to electronic products. Let us first take a look at how dust falls in love with electronic products. Since dust is an uneven dispersion system composed of particles suspended in the air, it mainly comes from industrial emissions, combustion smoke, and soil dust. These will float with the air. When they float above the circuit board, a certain electric field will be generated when the circuit board is working. These electric fields will attract dust and make it spill on the circuit board. If the dust on the circuit board is not removed, it will corrode the printed wires in the circuit board and the metal corners of electronic components. In severe cases, the printed wires will be broken. Usually, the printed wires will be moldy. The broken part will occur in the very thin signal line, the through hole of the multilayer circuit board, and the influence of the mold break on the circuit board is the control failure or ineffectiveness. In addition, the metal pins of electronic components are corroded, and even the metal pins are broken. If the component rust breaks in the power supply part, the entire circuit board will not work, and if it occurs in the control part, it will cause control failure. Another result is that electronic equipment runs up and down. For example, people who maintain electronic equipment usually have the feeling that electronic equipment operates normally when the weather is clear and dry, and when the weather is wet, this happens to the equipment. Such a weird malfunction! This is mainly caused by the accumulation of dust that is too thick. In dry weather, it will not cause any impact on the circuit board; but when in humid weather, the combination of dust and moisture will form an invisible resistance network. This resistance network is It will affect the electrical parameters of the circuit in the circuit board. If an invisible resistance is added to the power supply part, it will short-circuit the power supply part and burn the fuse, or cause the current of the power supply part to increase and the output voltage to be pulled down! If invisible resistance occurs in the control circuit, it will cause control failure. Therefore, it is very necessary to effectively prevent dust from entering the server in the cabinet! Since the current network equipment and servers generate a lot of heat during the operation of the cabinet, in order to dissipate this heat, they usually use active heat dissipation to dissipate the heat. However, due to the small space in the computer room, these equipment usually use air cooling. For heat dissipation, the heat dissipation holes cooperate with the convection air to bring dust into the equipment very efficiently. In addition, high voltage and static electricity will be generated when the equipment is working, which will attract dust in the air. For this reason, before the dust enters the server, we should effectively prevent the dust from entering the entire line of the cabinet heat dissipation hole. Therefore, we must install a cabinet brush on the cabinet heat dissipation hole. The main reasons are as follows:*** *, block dust. Installing cabinet brushes on the cabinet can greatly prevent dust from entering the electronic equipment, because the high-density arrangement of the cabinet brushes can effectively block. Second, clean and tidy cables. There are usually multiple electronic devices in the cabinet, which are connected by a lot of wires. Installing a cabinet brush in the cabinet can play a very good role in arranging the lines. The advantage of **** is that when the equipment fails The corresponding route can be found more quickly and conveniently. Third, prevent insects from entering. Another strong enemy of electronic equipment is small insects, such as cockroaches, ants and other small insects, which will also have a certain impact on the circuit board, and the cabinet brush can prevent the entry of dust while also preventing the entry of some insects. The editor of the cabinet brush recommends the use of pure nylon wool, which has better softness and fits well with the wire, making its sealing performance more outstanding, which can greatly reduce dust from entering the interior of the electronic equipment; the removal of the cabinet brush The pulling force is greater than or equal to 6KG, so that the cabinet brush is not easy to shed hair, the service life is longer and durable, and it can effectively ensure the stable operation of the electronic equipment for a long time.
