Problems solved by technology

Due to the noise frequency generated by the fan running, it will affect the read performance and write performance of the hard disk device
However, the fan in the server will adjust the speed according to the temperature inside the server, and different frequency noises will be generated at different speeds, so it is difficult to effectively eliminate the noise generated by the fan

Abstract

The invention provides a fan system and a sound suppression method thereof. A fan system is used for dissipating heat of an electronic device. The fan system includes a fan, a hollow structure, and acontrol circuit. Sound waves made by the fan are transmitted to an interior of the hollow structure when the fan is operating. The control circuit is connected to the hollow structure and is configured to control deformation / deformations of the hollow structure according to a state / states of the fan and / or the electronic device, which change a volume of the interior of the hollow structure for making a resonance frequency of the hollow structure being approximate to a rotation speed of the fan or being the same as the rotation speed of the fan. The provided fan system can make the resonance frequency of the hollow structure to be approximate to / be the same as a rotation speed of the fan so as to reduce the sound generated by the rotation of the fan; or the circuit is controlled to properlyadjust the thickness of the body, the distance between the fan and the bottom of a groove can be maintained at a proper value so as to inhibit the wind shear sound.

Description

technical field [0001] The present invention relates to a fan system and its sound suppressing method, in particular to a fan system capable of suppressing noises of different frequencies and its method. Background technique [0002] In the rack mount (Rack Mount) design of servers with high storage capacity, the fan is often arranged behind the hard disk device, and as the requirements for space utilization increase, the distance between the fan and the hard disk device is getting smaller and smaller. The frequency of noise generated when the fan is running will affect the read performance and write performance of the hard disk device. However, the fan in the server will adjust its rotation speed according to the temperature inside the server, and noises of different frequencies will be generated at different rotation speeds, so it is difficult to effectively eliminate the noise generated by the fan. [0003] In view of this, there is indeed a need for an improved fan syst...
