Background technology
Flourish along with electronics industry, the server handling ability as computing machine premium quality product is also more and more stronger.The formation of server and computer have a lot of similarity, all if any CPU (central processing unit), internal memory, hard disk, various bus etc., only it is the performance application that can provide various share service (network, database, file, printing etc.) and other side, its high-performance is mainly reflected in arithmetic capability, for a long time aspect such as reliability service, powerful external data handling capacity of high speed, is the maincenter of network and informationalized core.And once server fail, its economic loss brought is expected being difficult to.
Maintain the continual work of server, the heat-sinking capability of server internal just seems most important.For this reason, the common way of industry is fixed on the casing of server internal by the mode that a fan module is screwed, and cools the heater element of server internal.But when fan turns, usually can produce vibration, pasting is not shake larger when rotation speed of the fan is higher.These vibrations directly drive other elements of server internal to shake by casing, thus affect the performance of these elements.Meanwhile, these vibrations will cause server internal to produce noise.
But, due to the restriction of server internal spatial altitude, as the server of 1U, its internal height only has 44 millimeters usually, the deduction upper and lower thickness of slab of casing (about 3 millimeters) is only remaining 41 millimeters, inner space then, and the fan module of the general standard specification in market is 40 height at present, so avoid only remaining 1 millimeter, the design space of vibration passing, namely respectively only has the design space of 0.5 millimeter up and down.At narrow space like this, not only to consider coordinating of fan module and other elements, also will consider to design suitable shock-damping structure between fan module and casing.But under the condition of the damping space supercompression between casing and fan module, effect of shock-damping structure vibration damping is run counter to desire.Therefore, how industry letter major issue to be solved is become to the fan module damping in server narrow space.
