Taiwans SanJu Sharing Cooling Fans:Classification and Components

Back to list Release date: Sep 13, 2018

        With the development of science and technology, the function of electronic products is also getting stronger and stronger. In the process of using the computer, we will inevitably encounter heat generated by the electronic components, thus shortening the use time of electronic products and reducing the service life. So at present, the heat dissipation of electronic components becomes more and more important.


        The fan is the best way to solve the problem of heat dissipation.The fan uses forced heat convection to dissipate heat.With its own guiding role, it then uses heat exchange between air and heat sink to take away heat, thus realizing the " forced convection" of heat dissipation.The following San Ju motors in Taiwan will introduce the classification and components of the lower heat dissipation fan.


Classification of cooling fans:

1.According to the fan blade and air flow mode, it is divided into axial flow fan and centrifugal fan.

2.According to the working current, it is divided into DC fan and AC fan.

3.According to the purpose of the fan, it can be divided into:power fan, chassis fan, sound fan, car fan, refrigerator fan, notebook CPU fan and desktop computer fan.

Composition of cooling fan:

1.Rotor part:including fan blade, axis, magnetic ring and outer frame of magnetic ring.

2.Stator part:including motor, outer frame, bearing and connector. The control part consists of Hall IC, circuit board and a series of original parts.

3.Bearing part:As a key part of the life of the cooling fan, bearings also have a major impact on the working noise and manufacturing cost of the fan. The bearing system of the fan is generally divided into the following types:oil bearing, ball bearing, ceramic bearing, hydraulic Laifu bearing and dynamic pressure bearing.
