Radiator development has always been accompanied by two major themes of heat dissipation and mute. To improve the heat dissipation function; the simplest method is to improve the speed of the fan; the noise is also increased after the fan speed is improved. At this time, the noise comes from two aspects; When the air is squeaking; on the other hand, the sound of the friction of the mechanical equipment of the electric fan; this sound is emitted by the bearing. Some radiators whose quality is not close; often constitute a poor use of the electric fan; if you buy it Kind of product; can not be used for a long time to enjoy the fear noise brought by the bearing.
This makes it possible; as an important part of the electric fan, how many bearings are important to our radiators; the following fan bearings are more common in the market; let's take a look:
1. Oil bearing SleeveBearing
Oil bearing SleeveBearing: This kind of bearing can be said to be the old bearing skill in the market today; however, because the cost is low; the skill is simply completed; many products contain well-known brands are still using the edge; its strength is the initial use Quiet; low noise; cheap; but usually at the end because of the evaporation of internal fuel and the entry of dust; severe wear on the bearing; then slow down the speed; increased noise; average life expectancy of only 8000~15000 hours.
2, Lai Fu Bearing RifleBearing
RifleBearing: Rifle Bearing, developed by CoolerMaster, uses a shaft core with a reverse spiral groove and a sump; the oil in the fan operation will constitute a reverse migration; then the oil loss will be prevented; as an oil bearing The modified type; Laifu Bearing has been promoted to the service life of the bearing. From the cost and oil-bearing bearings, there is not much promotion; it can be said that the low-end product center is a better economical treatment method.
3, magnetic suspension hydraulic bearing HYDRAULICBearing
Magnetic suspension hydraulic bearing HYDRAULICBearing: The magnetic suspension hydraulic bearing technology introduced by AVC uses magnetic support suspension and the special oil film smooth with it; usefully handles the opposition between the long life and low noise of the electric fan.
4, nano bearing NACOOLBearing
Nano-bearing NACOOLBearing: introduced by FOXCONN; the new bearing materials made of nano-composite materials have a good performance in high temperature and wear resistance; this kind of bearing can be used to improve the anti-wear ability of electric fan bearings; and in a messy environment The application will not be affected too much; the service life will be more than 120,000 to 150,000 hours.
5, ball bearing BALLBearing
Ball bearings BALLBearing: Compared with oil-bearing bearings; ball bearings have changed the conflict method of bearings; this method is more useful to reduce the appearance of conflict between bearing surfaces; useful to promote the service life of fan bearings; The extended life span of the application is that the process is more messy; the promotion of the cost, together with 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; double ball bearing can reach more than 50,000 hours of service life; stability is very good; but it brings higher working noise and production capital.
There are different differences between the radiator products that use these bearing skills in the market; the most simple is the difference in price; knowing these differences can help us to decide according to individual needs when purchasing radiators; It also prevents some merchants from shoddy; let the individual spend money and can't reach the role that the individual wants.
