Background technique

Generally, when cooling electronic devices and electrical products, fans are often used to take away the heat directly or indirectly. In order to pursue better heat dissipation efficiency, fans with high speed are used, but the vibration frequency will also increase accordingly. The vibration generated by the fan running at high speed will be transmitted to the peripheral equipment of the fan. In addition to generating noise, it is also easy to cause damage to the peripheral equipment and reduce the service life of electronic devices and electrical products.
