With the development of Internet information age, Industrial DC Fans, Cooling fans, Cross flow fans and AC fans have been applied in many industries, such as household appliances, industrial equipment, electronic equipment, medical aviation and so on. Have you ever encountered such a situation? When the fan is used, the speed of the fan can meet the cooling requirements of the equipment, but when ...

How to measure the noise of cooling fan? What are the main factors related to the noise generated by cooling fans? How should we reduce the noise of cooling fans? How to measure the noise of cooling fan? Noise is the sound level generated by the cooling fan during operation, and its unit is decibel (dB). Quiet cooling fan, when measuring the noise of the cooling fan, it needs to be carried out in ...

Cooling fans are widely used, and their application environments are different. In harsh environments, such as outdoors, damp and dusty places, cooling fans are generally equipped with waterproof grade, that is, IPXX. IP is the abbreviation of Ingress Protection, and IP grade is the protection grade against foreign body intrusion of electrical equipment shell, which comes from IEC 60529, the stand...

The fan bearing system of cooling fan is mainly divided into sleeve bearing and ball bearing, while ball bearing is divided into single ball bearing and double ball bearing. Sleeve Bearing Sleeve Bearing is sintered from a copper-based powder. The use of the sleeve bearing requires lubrication to reduce the number of sliding friction. It can be said that it is the most common bearing technology in...

The cooling fans reliability of their bearings is very important, and the type of bearing used by the fan is also very important. So how to choose the cooling fan bearing system? The best fan bearing system for cooling fans is double ball bearing. The advantages and disadvantages of sleeve bearing, ball bearing in fan bearing system as follows: Advantages of using sleeve bearing 1. Resistant to im...

Generally, a cross flow fan has a multi-blade, long cylindrical impeller with forward multi-wing blades. At present, our cross flow fans are mainly divided into two types: AC cross flow fans and DC cross flow fans. Cross flow cooling fan has a complicated internal structure. Although its impeller circumference is symmetrical, its airflow activity is asymmetrical, and its relative velocity field an...
