Background technique
Along with developing rapidly of information industry, the continuous lifting of electronic parts and components motion speed, the used heat that the computer system running is produced also increases considerably thereupon.The used heat that is produced in the computer system operation process is not removed if do not loose, and can reduce the usefulness of computer system, even causes computer system to be damaged, and therefore, needs dynamical sink to loose and removes these used heat.The sink that computer system CPU is often used is fan, and for pursuing better radiating efficiency, the rotating speed of employed radiation fan is more and more faster, yet the vibration frequency that fan brought that runs up also improves thereupon.Be installed in the radiation fan on the cpu heat,, cause peripheral device to damage easily because the vibrations that fan brought that run up can be sent to CPU and peripheral as peripheral devices such as hard disks via radiator, thereby have influence on the performance of CPU and peripheral device.Radiation fan of the prior art is because rotating speed is too high, shakes excessively, influenced working life of computer.Therefore, because of the influence of vibrations, just become considerable problem when how to reduce the radiation fan running to CPU and peripheral equipment.
The model utility content
The utility model is in order to overcome defective in the above-mentioned prior art, by the structural design of U type damping device, can effectively offset the impact endurance test shock from the vertical, horizontal of radiation fan, reduces noise, and can effectively prolong the working life of equipment.
Damping device of the present utility model, the end angle that is installed on the cpu fan body is located, and comprises U type extension section, beam and base, and beam is positioned at two ends of U type extension section and is symmetrical arranged; Base is positioned at the beam inboard, and base diameter is less than the beam diameter; Establish screens between beam and the base.
Wherein, base is cylindrical, and is ringent two-stage structure.
Preferably, beam, base and U type extension section are one-body molded; Damping device is the rubber material.
In addition, the utility model also provides a kind of radiation fan of using above-mentioned damping device, comprises fan frame, fan body and flabellum; The place, end angle of fan body establishes stepped through hole, and the base clamping of stepped through hole and damping device is adaptive; U type groove is established, the U type extension section interference fit of U type groove and damping device in the corresponding position of fan frame inwall, stepped through hole.
Wherein, base diameter is greater than the axis of small circle of stepped through hole, and the beam diameter of damping device equals the axis of great circle of stepped through hole, and damping device is installed the outside that the described base in back is connected in stepped through hole roundlet.
Preferably, the end angle of fan body is four, and suitable with damping device quantity; Fan is an axial flow fan, and flabellum quantity is nine.
Compared with prior art, the utility model can be realized fan and treat flexibly connecting of heat radiation elements owing to be provided with U type damping device on cpu fan, effectively offsets the portraitlandscape impact endurance test shock, reduces noise.

Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-flabellum, 2-fans frame, 3-fan body, 4-damping device, 21-U type groove, the stepped through hole of 31-, 32-surface of contact, 41-beam, 42-U type extension section, 43-base, 44-screens.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
Extremely shown in Figure 5 as Fig. 1, the damping device 4 that is applied to cpu fan of the present utility model, the end angle that is installed on cpu fan body 3 is located, totally four at end angle, the fan body side is the X type.Damping device 4 comprises integrated beam 41, U type extension section 42 and base 43, and beam 41 is positioned at two ends of U type extension section and is symmetrical arranged.Base 43 is positioned at beam 41 inboards, and base is cylindrical, and is ringent two-stage structure, and base diameter is less than the beam diameter.Establish screens 44 between beam and the base.Damping device can adopt toughness materials such as rubber, is convenient to elastic telescopic.
The cpu fan of using above-mentioned damping device comprises flabellum 1, fan frame 2 and fan body 3, and fan is an axial flow fan, and flabellum quantity is nine.The place, end angle of fan body establishes stepped through hole 31, and the diameter of base 43 is greater than the axis of small circle of stepped through hole, because the opening shape structural design of base 43 after base 43 is filled in the roundlet of stepped through hole, is stuck in base 43 by screens 44 outside of roundlet.Because beam 41 diameters of damping device equal the axis of great circle of stepped through hole, the part of clamping back damping pad 41 is embedded in the great circle of stepped through hole again.U type groove 21 is established in the corresponding position of fan frame 2 inwalls, stepped through hole (being the place, end angle of fan body), and U type extension section 42 interference fit of U type groove 21 and damping device are so that install more firm.
When damping device of the present utility model is installed, with U type extension section 42 and 21 adaptive connections of U type groove, again ringent base 43 extruding are filled in the roundlet of stepped through hole 31, treat that base exposes fully, opening shape base restores to the original state, screens 44 this moment is stuck in the roundlet of stepped through hole 31, the lower surface of beam 41 and surface of contact 32 fit, the upper surface of the beam 41 after the installation can make radiation fan and flexible applying of heating components and parts (being CPU) two-part by beam 41 like this a little more than the upper surface of fan body.
Cpu fan of the present utility model can be realized flexibly connecting of parts owing to be provided with damping device, effectively offsets the portraitlandscape impact endurance test shock, slows down vibrations, reduces noise, and effectively prolongs the working life of equipment.Simultaneously, this damping device has better flexibility, can adjust the size and the thickness of beam according to different device demands flexibly, and form is changeable, and adaptability is stronger.Simultaneously, damping device of the present utility model not only can be applied on the CPU radiation fan, also can be applicable on the sink of other components and parts.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
