Description
[technical field]
The utility model relates to a kind of shock suction and combination device, particularly relates to the shock suction and combination device of a kind of radiation fan and substrate.
[background technique]
The electrical assembly of general computer equipment is in operation process, the capital produces sizable heat energy, this heat energy has only few part can scatter to the external world, and most heat can build up around electrical assembly, if untimely heat is dispersed, the temperature of electrical assembly continue to be raise, and then influence the normal operation of electrical assembly, even cause damage and can't use.Therefore, most computer equipment all can be provided with radiation fan, waves with the heat that utilizes this radiation fan that electrical assembly is produced when turning round and is dissipated to the external world, so as to reducing the temperature of electrical assembly, prolongs the working life of computer equipment.
All be provided with a ventilated port on the substrate of general computer equipment, and radiation fan is to be fixedly arranged in the substrate and corresponding to the position of this ventilated port, relend by driving this radiation fan running, be dissipated to outside the ventilated port and the heat around the electrical assembly can be waved, and then reach the purpose of heat radiation.Yet, be mostly between this substrate and the radiation fan to establish and mutually combine by screw lock, therefore, the vibrations when radiation fan is caused during in running just can be directly conducted on the substrate, cause this substrate also can make a noise thereupon producing vibrations.
For slow down radiation fan in when running to the vibrations that substrate caused, the manufacturer of computer equipment can set up a cushion pad again between this radiation fan and substrate now, to reach the purpose that reduces noise.And the vibration-absorbing structure of general computer equipment, mainly be as shown in Figure 1, shell 11 root edges of this radiation fan 1 are extended with location wall 12, and being correspondences, this location wall 12 is positioned at ventilated port 21 peripheries of substrate 2, one cushion pad 3 is set between the location of this radiation fan 1 wall 12 and substrate 2 again, and utilize as the connection piece 4 of screw and lock location wall 12, the cushion pad 3 and substrate 2 of establishing this radiation fan 1 in regular turn, make radiation fan 1, cushion pad 3 and substrate 2 positioning combination, and reach the effect of extenuating vibrations by the setting of this cushion pad 3.
Because this radiation fan 1 still need see through as the connection piece 4 and substrate 2 positioning combination of screw, when radiation fan 1 running, the vibrations that produced can conduct on the substrate 2 via these connection pieces 4 equally, and substrate 2 are produced shake thereupon and make a noise.Therefore, though the vibration-absorbing structure of general computer equipment has the function of use of the vibrations of extenuating, still the real genus of function of the shock-absorbing effect that can reach and anti-system noise is limited, and still has the space of demanding urgently improving.
[model utility content]
Therefore, the purpose of this utility model is to provide a kind of can absorb radiation fan really to the vibrations that substrate caused, and reaches the radiation fan that prevents noise result and the shock suction and combination device of substrate.

[embodiment]
As shown in Figure 2, a preferred embodiment of the shock suction and combination device 5 of this heat sinking fan and substrate is to comprise: a radiation fan 6, a buffer gasket 7, and a substrate 8.
This radiation fan 6 has an impeller 61, and a frame is located at the housing 62 of these impeller 61 peripheries.
Cooperate shown in Figure 3, this buffer gasket 7 is made by the rubber material of tool recovery, and this buffer gasket 7 has a cover that can overlap housing 62 end faces 621 that cover this radiation fan 6 and bottom surface 622 simultaneously and covers portion 71, and most these covers of being located at interval cover buckle portion 72 on portion's 71 outer circumferential faces, and these buckle portions 72 have more a body of rod 721, and one be located at these body of rod 721 bottoms and be slightly larger than the positioning block 722 of the body of rod 721 external diameters, and the positioning block 722 shown in the present embodiment is to be inverted cone shape.
This substrate 8 have that a plate body 81, is located on this plate body 81 and with the impeller 61 corresponding ventilated ports 82 of radiation fan 6, and most positioning holes 83 of being located on this plate body 81 and being adjacent to these ventilated port 82 peripheries.In the present embodiment, the internal diameter of these positioning holes 83 is the external diameters that are less than or equal to the body of rod 721 of aforementioned buckle portion 72, and each buckle portion 72 corresponding embedding that can supply this buffer gasket 7 respectively, and positioning block 722 retaining of these buckle portions 72 is formed on outside the plate body 81 of substrate 8, make this substrate 8 to reach mutual location with buffer gasket 7, simultaneously by the cover of this buffer gasket 7 cover portion 71 obstruct and and be formed with a spacing 9 between the radiation fan 6.
Continue as shown in Figure 3, the shock suction and combination device 5 of present embodiment radiation fan and substrate is when assembling, be by the recovery of this buffer gasket 7 and with its outside stretching, when buffer gasket 7 in when expansion, make its cover cover the housing 62 of portion 71 again corresponding to radiation fan 6, unclamp buffer gasket 7 this moment again, just can make its cover cover portion 71 is overlying on because of restoring force overlaps on this housing 62, be attached at the end face 621 and bottom surface 622 of this housing 62 simultaneously, make these buffer gasket 7 strong fixs on the housing 62 of this radiation fan 6 but borrow.
Afterwards, again with this radiation fan 6 and buffer gasket 7 corresponding ventilated port 82 tops that place this substrate 8, and in each buckle portion 72 corresponding each positioning hole 83 of embedding with this buffer gasket 7, positioning block 722 bars footpath by these buckle portions 72 all is slightly larger than positioning hole 83 simultaneously, be formed on outside the plate body 81 by retaining and can make positioning block 722 pass these positioning hole 83 backs, the unlikely disengaging to reach mutual fastening, borrow to make between this radiation fan 6, buffer gasket 7 and the substrate 8 to reach the more firm effect that combines.
After the shock suction and combination device 5 of present embodiment radiation fan and substrate is finished assembling, can intercept this radiation fan 6 and substrate 8 by the setting of this buffer gasket 7 fully, can reach firm combination simultaneously, locate the purpose of this radiation fan 6 and substrate 8, and not need to use in addition any connection piece to come in conjunction with this radiation fan 6, buffer gasket 7 and substrate 8.Therefore, the shock suction and combination device 5 of present embodiment radiation fan and substrate in design, there is no the object that can conduct vibrations between this radiation fan 6 and the substrate 8, with this understanding, absorb the vibrations that radiation fan 6 is produced by this buffer gasket 7 when turning round, just can prevent effectively that this substrate 8 from producing vibrations thereupon, and reach the effect of anti-system noise really.
Conclude above-mentioned, the shock suction and combination device 5 of the utility model radiation fan and substrate in design, can make the firmly combination of this buffer gasket 7, locate this radiation fan 6 and substrate 8, be enough to cause the connection piece that conducts vibrations and need not to use, relend recovery by this buffer gasket 7, the vibrations that radiation fan 6 is caused substrate 8 can be absorbed fully when running, and then the effect of anti-system noise can be reached.
