Description

Chassis fan guide structure

The present invention relates to a chassis fan guide structure, especially a chassis fan 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 network technology transmission efficiency and speed, computer server equipment needs to install more hard disk drives (HDDs) to perform related operations when processing the above-mentioned huge data operations. However, the heat generated by multiple hard disks during operation may reduce the performance of multiple hard disks or other adjacent electronic components, or even cause failures. Therefore, you must try to eliminate excess thermal energy to reduce the failure rate of the computer server. .
In order to solve the above-mentioned heat dissipation problem, in the existing server devices with multiple hard disks, the waste heat generated by the operation of the electronic devices in the server device is actively exhausted by the air flow generated by the higher-efficiency fan. The chassis of the server device uses a sheet metal bracket to directly fix multiple fans with shock-absorbing rubber nails, and then fixes the fans on the chassis. Therefore, when multiple fans are running at high speed, due to the air inlets of multiple fans and multiple hard disks The airflow is not buffered, so that the vibration caused by the very turbulent airflow directly affects multiple hard disks, and the aforementioned vibration frequency is just very close to the working frequency of the hard disk 1000 ~ 1500 Hertz (Hz), so that multiple hard disks are generated Resonance causes the reading rate of multiple hard disks to decline, which in turn affects the problem of the normal operation of the server as a whole.
