The radiator has been accompanied by the development of two major themes - cooling and quiet. To improve the thermal performance, the easiest way is to increase the fan speed, the fan speed increases the noise also followed larger. At this time the noise from the two aspects, on th e one hand, the whir of the the cutting air when the fan is running, on the other hand is the sound of the the fan machinery and equipment friction, this sound is bearing issued to. Some quality, but off the radiator, often resulting in a relatively poor use of the fan, if you buy that product, you may not be long before you can enjoy the bearing noise terrorist. slewing ring bearing
It can be, as a fan bearing an important part of our radiator how important it is the fan bearing these products on the market, we take a look at:
1, the oil bearing
Oil bearings: These bearings can be said that the old market bearing technology, however, because of the low cost, easy to implement technically, the early use of many products which include well-known brands are still continue to use its advantages quiet low noise, cheap; but it is generally to late due to internal oil volatiles and dust from entering the bearings cause serious wear and tear, which cause the speed to slow down, the noise increases, the average life span of only 8,000 to 15,000 hours.
2, to the blessing bearings
Laifu bearings: R & D Laifu bearing technology with a the reverse spiral groove and the shaft of the gear sump, oil-bearing fan is running a reverse migration, in order to avoid oil-loss, as the diverted to type of oil bearing Laifu bearings effectively enhance the service life of the bearings. Rather than from the cost and oil bearing not much improved, can be said to be the middle of the low-end products is a good economic solution.
3, maglev hydraulic bearing
Maglev the hydraulic bearing: the introduction of the magnetic levitation the hydraulic bearing technology utilizes magnetic support the suspensions role together with co-ordinated with the special film lubrication, effective solution to the contradiction between the long life and low noise of the fan. steel ball bearing
4, the nano-bearing
Nano-bearings: the nanocomposites made new bearing material in high temperature, good performance in terms of wear resistance, this bearing can effectively improve the wear resistance of the fan bearings, and will not be used in a complex environment too much impact, life up to 120,000 to 150,000 hours or more than ordinary bearings.
5, ball bearings
Ball Bearings: compared and oil bearing, ball bearing change bearing friction, more effective way to reduce the friction between the bearing surface phenomenon, effectively increasing the life of the fan bearings, so the heatsink. life extension. Brought drawback is that the process is more complex, the cost of upgrading, it also brings higher noise.
6, double ball bearing
Double ball bearing: ball also includes dual ball bearings and single ball bearing, double ball bearing service life can reach more than 50,000 hours, the stability is very good, but brought higher noise and manufacturing costs.
Radiator product on the market using the technology of these bearings have different differences, the most simple is the price difference between understanding these differences can help us in the purchase of the radiator to decide according to their own needs, but also Avoid Some businessmen shoddy to yourself 花了冤枉é'± and can not achieve the desired effect.
