Description

Fan fixer

Technical field

The present invention relates to a kind of fan fixer, particularly one can simplified structure, reduce manufacturing cost, increase space utilization rate, and be beneficial to the fan fixer of fan fast insert-pull.

Background technology

Because electronic installation can produce heat in the time operating, especially the device such as server, host computer, for avoiding heat effects operational paradigm or assembly being caused to damage, therefore must fan be set or heat abstractor dispels the heat, with regard to server, conventionally array is provided with many group fans, the fixed form of this many groups fan, normally adopt two groups of front and back dividing plate and side dividing plate fan attachment, must take sizable space and just can produce the two groups of diaphragm structures in front and back, and two-layer different separator material and die sinking expense are also quite expensive.

For patent, U.S.'s patent of invention 7245490 " Screw-free fan bracket mounting structure ", this case discloses one and exempts from screw fan support fixing structure, this is exempted from screw blower tray structure and comprises, one blower tray and a holder, utilize the upper protruding block on blower tray, fastening piece and lower snap fit be the corresponding upper combined hole that is bonded to holder respectively, fastening hole and lower combined hole, and make distance between fastening piece and the lower snap fit in blower tray be slightly larger than fastening piece in holder and the distance of lower combined hole, make blower tray produce plastic deformation, and with the elastic-restoring force of this deformation, blower tray is incorporated on holder, this case in specification and unspecified fan how to be assembled on this blower tray, or illustrate that fan is arranged at the state on blower tray, the main demand of this case is only can be to reach the effect of fast assembling-disassembling blower tray without the design of screw, but system hangs on holder side due to blower tray, stationarity and supportive for fan make us leaving a question open, and because blower tray is to be incorporated on holder by the elastic-restoring force that produces plastic deformation, after long-time use, the phenomenon such as will inevitably produce distortion or elastic force is tired, cause blower tray cannot firmly be incorporated into holder.

For another example U.S.'s patent of invention 6244953 " Electronic device fan mounting system ", this case discloses a kind of fan mounting system of electronic installation, it comprises a L-shaped pedestal, this pedestal has a front side board and a base plate, these front side board both sides are provided with a fin, this base plate bilateral symmetry is respectively provided with one jiao of seat, between these two jiaos of seats with this base plate, between front side board, form a space in order to hold a fan, in the fin that is provided with snap fit and can provides this pedestal front side board in the side plate of a casing is sticked in, the main demand of this case is also the fan attaching device that is to provide a kind of fast demountable, but because the fin of its pedestal front side board both sides outwards protrudes out, and must coordinate the set snap fit of casing, therefore take many spaces, and its structure cannot be close to setting by adjacent two pedestals, that is, between two fans, will inevitably there is spacing, cannot effectively utilize the space in casing.

For another example TaiWan, China new patent M285896 " fan fixer ", the fan fixer that this case discloses, comprise that an installing rack and that is fixed on this pedestal is in order to be fixed to this fan the fixture of this installing rack, this installing rack comprises biside plate, a hole clipping is offered respectively in one end of this biside plate, this fixture comprises the flexible fixed part of two tools, and each fixed part is convexly equipped with a fixture block to the hole clipping of respective side panels that should installing rack, and this two fixed part is established respectively an operating portion; This case mainly relies on and is arranged at the fixture at fan top and the biside plate of installing rack engages mutually, but in fact, this biside plate must connect a substrate, form an accommodating framework of fan with three faces by biside plate and substrate, otherwise this biside plate will inevitably produce and deflect, and fan is also as easy as rolling off a log by skidding off between biside plate, therefore, the effect of this substrate is equal to backboard, just this case separates backboard to arrange, and the accommodating framework of the fan with three faces that its biside plate and substrate form, necessary whole group of replacing, forms waste.
