There are many types of industrial fans on the market. At least the most commonly used DC cooling fans enjoy a wide application, mainly including kitchen equipment, chassis, electrical products, LED lighting, professional audio equipment, purification equipment, refrigeration equipment and other traditional or modern equipment in all walks of life.
For example, the DC cooling fans are usually assembled with the radiator fin to become a complete radiator to dissipate heat for the case system and various computer chips, so as to reduce the working temperature of machinery equipment and increase the service life of machinery equipment.
This is the main role of the DC cooling fans on the computer. However, it is also a part of the equipment that uses the air volume and pressure of the fan to improve the use of the machinery equipment. For example, the gas table also uses the working pressure of the fan to make the ball drift on the table.
Choosing DC cooling fans suitable for your own equipment can not only make the production and processing of enterprise products more effective, but also make other products work safely.
The abnormal sound of the electronic cooling fan is different from other noises. The noise can only sound like a simple sound, while the abnormal sound has other sounds (with more than two kinds of sounds coming out). The abnormal sound may be caused by other things or deformation in the rolling bearing, or the impact of improper assembly, or the uneven winding of the motor winding that results in loosening.
Everyone usually uses the method of listening. Influenced by subjective, it is difficult to identify and it is very easy to raise objections. If the total number of electronic cooling fans used is large, you can rely on spectrum analysis equipment to query, and the kinetic energy distribution of the noise frequency band can identify abnormal sound.
At this stage, industrial electronic cooling fans can dissipate heat and remove dust from machinery equipment, and maintain indoor ventilation in the production workshop. The electronic cooling fan is widely used, so it is necessary to understand the reason why the electronic cooling fan has abnormal sound.
The heat from the CPU is first transferred to the heat sink and then blown by the cool air of the electronic cooling fan to take away the heat from the heat sink. The heat transfer rate of the electronic cooling fan is determined by the material of the thermal conductor that makes up the electronic cooling fan, so the quality of the material of the radiator directly determines its thermal conductivity. When selecting a electronic cooling fan, people must pay attention to the thermal conductivity of the electronic cooling fan.
Among the materials with better thermal conductivity at this stage, copper is a metal material with high heat transfer performance. If copper is used to manufacture radiator fins, the heat dissipation effect will be very good. But the copper texture is stronger and heavy, and the difficulty coefficient of production and processing is very high. Besides, the cost is high, so it is difficult for people to see radiator fins made of copper at this stage.
