As we all know, there are many industries in the market
Cooling fan, Small to electronic products, large to refrigerator cabinets, cooling fans to ensure that the product temperature is controlled within a controllable range and extend the service life of the product. The cooling fan market is large, and the competition among cooling fan manufacturers is fierce. Different manufacturers have different models and functions of cooling fans. Consumers have some headaches when choosing cooling fans. They don't know which one to choose. Now let's learn about it together.
One: bearing type
Bearings are divided into ball bearings and oil bearings. Oil bearing is a sleeve bearing that uses sliding friction and uses lubricating oil as lubricant, which is a common bearing technology in the market. This bearing is low in cost and simple to manufacture. Its advantages are quiet in initial use, low in noise and low in price. Ball bearings use rolling friction. There are some steel balls or steel columns between the two iron rings, and some grease is assisted for lubrication, this method more effectively reduces the friction phenomenon between the bearing surfaces, effectively improves the service life of the fan bearing, and therefore reduces the heat generation of the radiator and prolongs the service life.
Two: fan noise
In addition to the heat dissipation effect, the working noise of the fan is also a common concern. Fan noise is related to friction and air flow. The higher the fan speed and the greater the air volume, the greater the noise, and the vibration of the fan itself is also a factor that cannot be ignored. To solve this problem, we try to use a larger fan. In the case of the same air volume, the working noise of the large fan at a lower speed is less than the working noise of the small fan at a high speed. Another factor that we can easily ignore is the fan bearing. The friction collision between the shaft and the bearing is also a major source of fan noise. Therefore, it is recommended that consumers choose a strong manufacturer to purchase when purchasing a cooling fan to ensure quality.
The above is the use of cooling fan noise and noise difference judgment small knowledge sharing.
