Description

Chassis fan diversion structure

The present invention relates to a chassis fan flow guide structure, in particular to a chassis fan flow guide structure that can reduce the airflow vibration of the fan unit and the resonance of the storage unit, and improve the working efficiency of the storage unit.

Due to the continuous improvement of the transmission performance and speed of current network technology, computer server equipment needs to install more hard disk drives (HDD) to perform related operations when processing the aforementioned huge data operations. However, the heat generated by multiple hard drives during operation may cause the performance of multiple hard drives or other adjacent electronic components to decrease, or even malfunctions. Therefore, we must try to eliminate excess heat to reduce the failure rate of computer servers. .

Therefore, when multiple fans are running at high speed, the air inlets of multiple fans and multiple hard disks The airflow is not buffered, so that the vibration caused by the airflow is very turbulent and directly affects multiple hard disks. The aforementioned vibration frequency is just close to the working frequency of the hard disk at 1000~1500 Hz (Hz), causing multiple hard disks to generate Resonance causes the reading rate of multiple hard drives to drop, which in turn affects the normal operation of the server as a whole.
