[Do you know how to correctly select a DC fan for heat dissipation?

Release time:

2019-07-10

Many people are looking for a few manufacturers when choosing DC cooling fans, and then compare the price to decide, but when choosing DC fans, you can't just look at the price. Here we will teach you how to correctly select the DC fan. 1. Listen to the noise: the same speed, the same voltage, the smaller the noise of the DC cooling fan is better, because the low noise is mainly related to the fan blades, bearings, oil products, assembly structure, etc. The better the shape design of the fan blade, the greater the air volume and the lower the noise; the higher the bearing accuracy, the smaller the friction between it and the shaft core, the more accurate the size matching, and the lower the noise of course; Noise is low, it means friction

Many people are looking for a few manufacturers when choosing DC cooling fans, and then compare the price to decide, but when choosing DC fans, you can't just look at the price. Here we will teach you how to choose correctly.DC Fan.
1. Listen to the noise: the same speed, the same voltage, the smaller the noise of the DC cooling fan is better, because the low noise is mainly related to the fan blades, bearings, oil products, assembly structure, etc. The better the shape design of the fan blade, the greater the air volume and the lower the noise; the higher the bearing accuracy, the smaller the friction between it and the shaft core, the more accurate the size matching, and the lower the noise; The lower the noise, it means that the friction is small, the life of the bearing and the shaft core will be longer, and the life of the DC fan will also be longer.
2. Look at the current: the same speed, the same voltage, the same air volume. Current small DC cooling fan is better. Because the smaller the current, the smaller the fan loss, that is, the smaller the power consumption. The main reason for the small power consumption is that the product has strong magnetic permeability, good loss of motor enameled wire, and high copper content. D lubricating oil has high activity.
3. Vibration measurement: For fans of the same specification and speed, DC cooling fans with low vibration are better. DC cooling fans are a high-speed running machine. There must be some vibration. No manufacturer can guarantee that there is no vibration. The smaller the vibration, the better. The smaller the vibration, the more stable the fan operation, and the smaller the loss of the bearing and shaft core, it will also reduce the volatilization of oil or the wear of the ball, and the life will of course be longer.
