Shock absorbing structure and its series fan

The present invention relates to a shock absorbing structure and a series fan thereof, and more particularly to a shock absorbing structure for reducing vibration generated when a fan rotates, and a series fan having the shock absorbing structure.

With the rapid development of today's information technology, a large amount of information data needs to be calculated, integrated, transmitted and stored. In response to such a huge data technology, the base station of the server is responded to; according to different computing capabilities, the server is divided into two parts. Workgroup level servers, departmental servers and enterprise servers.

Servers, as hardware, usually refer to computers that have higher computing power and can be used by multiple users. Compared with ordinary PCs, servers need to work continuously in a 7X24-hour environment.

This means that the server needs more stability techniques to ensure data transfer.

In order to ensure the correctness of reading and writing, the internal disk of the server will detect the magnitude of the vibration to feedback the control of the head, which will affect the speed of reading and writing. In order to pursue the highest read/write efficiency, each storage device or server manufacturer evaluates the size of the hard disk vibration by the Rotation Vibration (RV) of the hard disk. Generally, to improve the read/write efficiency, in addition to actively enhancing the hard disk. In addition to its structural characteristics, it is also passively applied with gaskets or shock absorbing materials to reduce the impact of vibration on the hard disk.

Another source of vibration is the cooling fan required inside the server. Each fan manufacturer also improves the vibration transmission from the active motor efficiency and the blade to reduce the vibration transmission to the hard disk, or passively shims or shock absorbing materials on the fan bracket.
