散热风扇用不了多久就坏了，我们一起看看是受什么因素影响。

Why did the cooling fan break after a short period of use?Let’s take a look at the factors that will affect the service life of the fan.

质量和制造：优质的风扇通常采用高品质的轴承、电机和叶片，更加耐用可靠。

Quality and Manufacturing: high quality fans typically use high-quality bearings, motors, and blades, making them more durable and reliable.

轴承类型：常见的轴承类型包括滚珠轴承和液压轴承。滚珠轴承通常具有更长的寿命和较低的摩擦，而液压轴承则在噪音和振动方面更有优势。

Bearing Types: Common bearing types include ball bearings and hydraulic bearings. Ball bearings generally have longer life and lower friction, while hydraulic bearings have advantages in terms of noise and vibration.

使用环境：如果风扇经常在高温或潮湿的环境中工作，就会增加机械磨损和电气故障的风险。

Usage environment: If the fan often works in a high temperature or humid environment, it will increase the risk of mechanical wear and electrical failure.

转速和负荷：过高的转速或长期运行在高负载下 会导致轴承过度磨损和故障。

Speed and load: Excessive speed or long-term operation under high load will cause excessive bearing wear and failure.

温度管理：如果风扇频繁运行在高温环境下，会加速零部件的老化和磨损，从而缩短寿命。

Temperature management: If the fan frequently runs in a high-temperature environment, it will accelerate the aging and wear of parts, thus shortening its life.

维护和清洁：灰尘、污垢和杂物的积累会导致风扇叶片的不平衡和阻塞，影响散热效果并增加机械负荷。

Maintenance and Cleaning: The accumulation of dust, dirt, and debris can cause imbalance and blockage of fan blades, affecting heat dissipation and increasing mechanical load.

需要注意的是，散热风扇的寿命是由多个因素综合作用决定的，其中某些因素可能相互关联。因此，在选择、使用和维护风扇时，需要综合考虑各种因素，并遵循制造商的建议和指导。

It should be noted that the life of a cooling fan is determined by a combination of factors, some of which may be interrelated. Therefore, when selecting, using and maintaining a fan, it is necessary to consider various factors and follow the manufacturer's recommendations and guidance.
