Fan bearing difference
Radiator development has been accompanied by two major themes - cooling and mute. The easiest way to improve the heat dissipation performance is to increase the fan speed. As the fan speed increases, the noise also increases. At this time, the noise comes from two aspects. On the one hand, the sound of cutting the air when the fan is running, and the other is the sound generated by the friction of the fan mechanical equipment. This sound is emitted from the bearing. Some radiators whose quality is not good often cause poor use of the fan. If you buy that kind of product, it may take a long time to enjoy the horrible noise caused by the bearing.
From this, how important the bearing as an important part of the fan is to our radiators. These fan bearings are more common in the market. Let's take a look:
1. Oil bearing SleeveBearing
Oil bearing SleeveBearing: This type of bearing can be said to be the older bearing technology on the market. However, due to its low cost, it is technically easy to implement. Many products, including well-known brands, are still in use. The advantage is that it is used initially. Quiet, low noise, low price; but generally in the later period due to the internal fuel volatilization and the entry of dust, causing serious wear on the bearing, resulting in slower speed, increased noise, and an average life of only 8,000 to 15,000 hours.
2, Lai Fu Bearing RifleBearing
RifleBearing: Rifle Bearing, developed by CoolerMaster, uses a shaft core with a reverse spiral groove and a slinger. When the fan is running, the oil will form a reverse migration, thus avoiding oil loss and acting as an oil bearing. Reconstruction type, Laifu bearing effectively improves the service life of the bearing. Compared with oil-bearing bearings, there is not much improvement in cost. It can be said that it is a relatively good economic solution in the middle of low-end products.
3, magnetic suspension hydraulic bearing HYDRAULICBearing
Magnetic suspension hydraulic bearing HYDRAULICBearing: The magnetic suspension hydraulic bearing technology introduced by AVC utilizes the magnetic support suspension effect and the special oil film lubrication matched with it, effectively solving the contradiction between the long life and low noise of the fan.
4, nano bearing NACOOLBearing
NACOOLBearing: Introduced by FOXCONN, the new bearing materials made of nanocomposites have good performance in high temperature and wear resistance. These bearings can effectively improve the wear resistance of fan bearings and in complex environments. The use will not be affected too much, and the service life will be increased to 120,000~150,000 hours compared with ordinary bearings.
5, ball bearing BALLBearing
Ball bearing BALLBearing: Compared with oil-impregnated bearings, ball bearings change the friction mode of the bearing. This method is more effective in reducing the friction between the bearing surfaces, effectively improving the service life of the fan bearing, and thus the radiator. The service life is extended. The disadvantage is that the process is more complicated, resulting in higher costs and higher operating noise.
6, double ball bearing DUALBALLBearing
Double ball bearing DUALBALLBearing: Double ball bearing is also included in the ball bearing. Compared with single ball bearing, the double ball bearing can last for more than 50,000 hours. The stability is very good, but it brings higher working noise and manufacturing cost.
There are different differences between the radiator products using these bearing technologies on the market. The simplest is the difference in price. Understanding these differences can help us decide when we purchase the radiator, and also according to our own needs. Avoid some merchants shoddy, let yourself spend money and can not achieve the effect you want.
