Communication equipment is developing rapidly in this era, and many new things related to it emerge in an endless stream. With the emergence of new products and technologies such as mobile communications, Internet of Things, artificial intelligence, and power batteries, as well as their high heat flux density, high power, and ultra-thin characteristics, this also puts forward higher requirements for heat conduction and heat dissipation. . For its usage scenarios, it is particularly important to choose a quiet ventilation fan. So based on these requirements, how do we choose a low-noise cooling fan? 

First of all, we must understand the noise. The noise is caused by the vibration of the fan when it is running. Excessive vibration will affect the stability of 5G terminal equipment. Not only that, but it will also indirectly interfere with device communication, especially when small 5G terminal devices are used indoors, the noise impact is even more serious. The cooling fan with good quiet effect is even more important. While ensuring the cooling effect, choose a fan with low noise as much as possible.

When designing the cooling fan, try to choose the static pressure impeller design. At the same speed, the cooling fan designed with static pressure impeller has a larger air volume and lower noise.

The material of the silent fan is to use PBT frame and fan blades as much as possible, with smooth surface, wear resistance, brittle resistance and good toughness. The bearing system of the fan adopts ball bearings, and the noise level is stable. Unlike oil bearing exhaust fans, the longer the use time, the louder the noise, and the service life is not as good as the ball bearing exhaust fans.

In addition, when adapting to a more intelligent cooling fan with speed regulation, whether it is a communication device or other smart devices, there are no-load and load cycles. The speed-regulation fan can reduce the speed when it is no-load, and the noise value will also be greatly reduced.
