Many people will use cooling fans, especially AC cooling fans are very commonly used in life. When ordinary consumers buy AC cooling fans, few people will notice the life of the cooling fans, mainly depending on the air volume of the fans., Wind speed and noise, current, voltage, and power. When users choose cooling fans, they all hope that the longer the service life is, the better under the condition of meeting the air volume. As a result, the primary specification under the demand of equipment warranty is short-lived. Short-lived can reduce the maintenance cost of users and the frequency of changing micro fans during operation. So what is the relationship between the service life of AC cooling fans? The following cooling fan manufacturer Jiance Electronics said: The life of the cooling fan is related to the bearing used, the operating environment temperature of the cooling fan, and the balance of the fan blades. 1. Cooling fan using bearings:
1.1 the use of double ball bearings, double ball bearings are relatively high-end bearings, the use of long life, in the 50000-100000h.
1.2 the use of oil bearing, oil bearing service life in 10000h.
1.3 the use of hydraulic bearings, with a larger oil storage space than the oil bearing, the service life of about 40000h. (Life when running at room temperature), so the selection of bearings accounts for a large proportion of the life of the cooling fan.
2. The cooling fan uses the operating ambient temperature: When the cooling fan is running, the higher the ambient temperature, the easier it is to reduce its life.
3. The poor balance of the cooling fan blades will cause the cooling fan to vibrate. A long vibration time will increase the noise and cause weightlessness, and then the fan may be directly stuck. This is the reason why many users do not pay attention to the above problems before they buy a cooling fan. Jiance Electronics recommends that you pay attention to the above problems in the process of application, whether you buy an AC cooling fan or a DC cooling fan, so as to make your cooling fan last longer.
