Description
【Technical field】
The present invention relevant a kind of shock-damping structure and its fan, it is particularly a kind of to reduce subtracting for fan vibrations produced when rotating
Shake structure, and the fan with this shock-damping structure.
【Background technology】
Under information technology now flourishes, substantial amounts of information data need calculated, integrated, transmitted with storing, to deal with
So huge data technique cause the base station of servomechanism in response to and give birth to；According to different computing capabilitys, servomechanism is divided into work again
Make group level servomechanism, department level servomechanism and enterprise-level servomechanism.
For servomechanism is as hardware, typically referring to those has higher computational power, using the teaching of the invention it is possible to provide make to multiple users
Computer, is compared with common PC, and servomechanism needs continuously to be operated in 7X24 hours environment.This means that servomechanism is needed
More stability techniques are wanted to ensure data transmission.
Disk drive is in order to ensure the correctness of read-write, the size of meeting detecting vibration, with the control of feedback read/write head in servomechanism
System, will so influence the speed of read-write.Each storage facilities or servomechanism manufacturer, in order to pursue highest read-write efficiency, just with
The rotation vibrations of hard disc（Rotation Vibration,RV）To assess the size of hard disc vibrations, read-write effect is typically such as improved
Rate, in addition to actively strengthening the architectural characteristic of hard disc in itself, supplied shim that also can be passive or damping material are to reduce vibrations pair
The influence of hard disc.
Another vibrations source is the radiator fan needed for inside servomechanism, and each fan producer is also from the moyor of active
Set about improving reduction vibrations with flabellum and be transferred to hard disc, or passive in shimming on blower tray or damping material, with reduce because
Vibrations caused by fan are to lift hard disc reading efficiency.But on the whole effect is still limited, vibrations may be reduced
But heat-sinking capability is sacrificed, or cost increase is caused because of additional mechanism member.
Therefore how to solve above-mentioned problem and missing, as phase shutout of the inventor of this case with being engaged in the industry
