变频风扇和一般风扇有什么分别：变频风扇超静音、更省电、更美观、超智能。变频风扇最大的优点就是静音，其次相对来说较为省电，另外变频风扇吹出的风要比普通风扇要柔和。
What is the difference between the frequency conversion fan and the general fan: the frequency conversion fan is super silent, more power-saving, more beautiful and super intelligent. The biggest advantage of the frequency conversion fan is mute, and the power consumption is relatively low. In addition, the wind of the frequency conversion fan is softer than that of the ordinary fan.

1、变频风扇有直流和交流变频，是将电子调节电压或电流改变风速大小，功能上的正常风、自然风、睡眠风、智能风等都是通过控制芯片调节电压或电流实现的。
1. The frequency conversion fan has DC and AC frequency conversion, which changes the wind speed by electronic regulating voltage or current. The normal wind, natural wind, sleep wind and intelligent wind in function are all realized by controlling the voltage or current by the chip.
2、一般风扇只是通过改变风扇上面的线圈绕组从而达到改变风力大小的目的。
2. In general, a fan can change the wind power only by changing the coil winding on the fan.
3、变频风扇最大的优点就是静音，其次相对来说较为省电，节能减排，变频风扇送风稳定，变频技术最大的特点就是运行平稳。
3. The biggest advantage of the frequency conversion fan is mute. Secondly, it is relatively energy-saving, energy-saving and emission reduction. The frequency conversion fan has stable air supply. The biggest feature of the frequency conversion technology is stable operation.
风扇清除噪音
Fan noise removal
一、润滑轴承
1、 Lubricating bearing
风扇转运最主要的部件就是轴承，时间长了缺乏润滑油，这样高速转动时就会产生噪声。因此，我们只需要在风扇轴承上滴几滴润滑油，如果没有使用缝纫机代替也可以。但是注意千万不要使用食用油来替代，因为其颗粒比较大，容易对轴承产生伤害。
The most important part of the fan transport is the bearing. There is a lack of lubricating oil after a long time, so the noise will be generated when the fan rotates at high speed. Therefore, we only need to drop a few drops of lubricating oil on the fan bearing, if not replaced by a sewing machine. But pay attention not to use edible oil to replace, because its particles are relatively large and easy to damage the bearing.
二、固定扇叶
2、 Fixed leaf
震动噪音亦是风扇噪音的一个重要组成部分，因为叶片在轴承上的松动以及轴承磨损导致间隙变大等，因此只需要拆下分扇，把螺丝钮紧，这样牢牢固定之后，就不会再震动。
Vibration noise is also an important part of fan noise. As the blade loosens on the bearing and the bearing wears, the clearance becomes larger. Therefore, it is only necessary to remove the fan and tighten the screw, so that after it is firmly fixed, it will not vibrate again.
三、打磨扇叶
3、 Grinding fan blade
另外使用质量较差的散热风扇，扇叶的重心可能没有处在轴心上，形成“偏心”，使用时间一长，风扇的“偏心”现象会变得越来越严重，这不仅会产生噪音，严重的还可能损坏 CPU。对此，可以将共拆下来，然后用细线吊在其中心位置，待其静止后看其向哪一方向下沉，一直待风扇能够处在水平位置之后再将其安装上去即可。
In addition, if the cooling fan with poor quality is used, the center of gravity of the fan blade may not be on the axis, forming “eccentricity”. As the use time is long, the “eccentricity” of the fan will become more and more serious, which will not only generate noise, but also damage the CPU seriously. In this regard, it can be removed, and then it can be suspended in its center position with thin wire. When it is still, it can see which direction it sinks, and then it can be installed after the fan can be in the horizontal position.
