Tong chi manufacturer to failure of the cooling fan is analysed and the analysis of the reasons
the main cause of the cooling fan noise are: fan dust, normal wear and tear, motor damage, etc.
a, fan dust: a cooling fan air convection produced at work for laptop heat dissipation at the same time, also put the dust in the air and stay in their surface cooling near the mouth, not only affects the cooling effect, and increase the cooling fan of the load at the same time,
has also changed the air convection environment, leading to the noise. This kind of phenomenon if dust removal in time, will not affect the parts; If not dust in time, as time passes can cause fan shaft wear to produce blades 'eccentric', this kind of noise, only replace the cooling fan can solve the problem.
2, normal wear and tear:
a cooling fan blades 'eccentric' is a major cause of noise. Fan blade's center of gravity on the axis, when running smoothly, sound is very small, but with daily use wear, will produce a certain deviation, the focus of blades did not cause any 'eccentric', on the axis of the fan after rolling, is equivalent to an oscillator ( Oscillator is on the motor shaft with an eccentric wheel) , along with the use of time longer, fan bearing wear, exacerbated vibration noise.
3, motor damage:
a cooling fan is an easy wear parts, the motor after reach the design life or be affected with damp be affected with damp internal short-circuit, overload, power surge is likely to lead to motor damage, the fault belongs to the normal phenomenon, replace the fan can be solved.
4, use advice:
wind cooling fan is normal in a work, but when you find the fan sounds than buyers increased sharply with wind or with the normal work of significant differences ( If there are any scratching, crash) When need a maintenance or dust cleaning fan. Advice service engineer, please help clean up the dust fan.
this is the cooling fan manufacturer small make up to you about the cooling fan of the main causes of failure and the solution, you know? Here we also not much said, hope this article can help to you.
