With the development of science and technology, the function of electronic products is more and more strong. We use the computer in the process, will inevitably encounter the heat generated by the original electronic heat, resulting in shorten the use of electronic products, reduce the service life. So now, the electronic heat of the original becomes more and more important.
The fan is the best way to solve the heat, the fan is the use of forced thermal convection to the way the heat, by virtue of their own diversion, and then use the heat and heat between the heat exchange away heat, in order to achieve "forced Convection "of the heat
Fans are also divided into many categories, summed up can be divided into three points:
1. According to the wind and air flow is divided into: axial fan, centrifugal fan.

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

3. According to the use of the fan is divided into: power fan, chassis fan, audio fan, car fan, refrigerator fan, notebook CPU fan and desktop computer fan.
The composition of the fan: 1. Rotor part: including fan, axis, magnetic ring and magnetic frame. 2. Stator part: including motor, frame, bearing and connector. The control section consists of Hall ic, circuit board and
A series of original pieces. However, the bearing is as a fan of the life of the bottleneck of the existence of factors, through the fan when the work of noise, resulting in the cost of a total impact. Fan bearing system in general
Divided into a few (according to the price of the first listed one by one): oil bearing, ball bearings, ceramic bearings, hydraulic blessing bearings and dynamic pressure bearings.
The above is the working principle of the fan and the composition of the device, we hope to help everyone, more relevant fan knowledge, please pay attention to "Shenzhen Bao Di Kai"
