Description
Technical Field
The invention relates to the technical field of fan damping equipment, in particular to a server fan damper.
Background
With the rapid development of computer technology, data center servers are being deployed in high-density, even ultra-high-density directions to meet high-performance computing service demands. And a large amount of heat is generated in the running process of the server, so that the server needs to be cooled in order to ensure the normal running of the server. The use and impact resistance of a high speed fan as the primary cooling device in a server plays a critical role in improving server performance. The rotating speed of a high-speed fan used by a server in the current market is as high as 17000rpm-24000rpm, so that the vibration is large, the noise is large, and the working environment of a mechanical hard disk is further deteriorated; the hard disk used by the server is mainly two kinds of mechanical hard disks and solid state hard disks. Solid state disks are strong in impact resistance and high in speed, but due to the high price, the use of mechanical disks in servers is dominant. When the mechanical hard disk works, the magnetic disk rotates at a high speed, the magnetic head floats on the disk surface by virtue of the resistance of air, the servo mechanism drives the magnetic head to radially move along the disk surface, so that the magnetic disk is read/written, and when the server is subjected to vibration and impact in the use process, the hard disk can stop rotating and die. Because the server is developed towards high power density, the space of the hard disk installation place is limited to a great extent, so that the read/write performance of the mechanical hard disk can be guaranteed only from the beginning of a seismic source, and the high-speed fans in the market at present are all placed in a high-speed fan frame directly, and no special damping device is adopted.
In the technical field of vibration reduction, various devices needing vibration reduction are changed into elastic supports by adopting various vibration absorbers, wherein the rigid connection between the devices and a foundation is commonly known as a spring steel wire vibration absorber which has the excellent characteristics of nonlinear rigidity, high damping, low frequency, good impact resistance effect, long service life and the like, is oil-resistant, seawater-resistant, sunlight-resistant and high and low temperature-resistant, and is widely applied to the fields of vibration isolation and impact resistance of ships, spaceflight, aviation and vehicles, and electronic devices, and the existing spring steel wire vibration absorbers, such as the vibration absorbers used as high-speed fans of servers, have the following problems:
the load is large-the minimum bearing of the single shock absorber with the existing specification is 1.5 kg, and the mass of the server high-speed fan is not more than 0.8 kg;
large-minimum height of 20mm for existing specification vibration isolation, while the high speed fan tray of the server cannot provide such large size space;
lateral instability-a conventional single spring wire shock absorber is prone to sway in a vibrating and impact environment, causing lateral instability; for this reason, a plurality of dampers are often used in combination, and as a result, the bearable load is larger, the size is larger, and the applicability to the server high-speed fan is poorer.
In view of the above problems, no one in the art has thought to adopt the prior art similar to the spring steel wire shock absorber aiming at the special requirements of the high-speed fan of the server, and seeks to solve the new breakthrough of the vibration isolation technology of the high-speed fan of the server.
