Abstract
A blast fan comprises a set of fan blades and upper and lower edges. The blades are fixed via the upper and lower edges. Between every two blades is disposed a reinforced rib to strengthen the mechanical structure of the blades set, so as to absorb the vibration of the blades, thus achieving good results of reducing noise.
Description
[technical field]
The present invention relates to a kind of blower fan.
[technical background]
General electronic equipment such as computer all can produce heat in the process of operation, if these heats are not in time discharged, heat will be cumulative, finally causes equipment to move even to damage.Main heating source in the computer is the power supply unit in central processing unit (CPU) and the computer housing, in the prior art, usually by the heat discharge of installing radiator on the central processing unit (CPU) and the mode of installing fan produces central processing unit (CPU) on radiator, in addition, fan also is housed so that the heat of its generation is discharged in the power supply unit.
Along with computer industry constantly develops, the high frequency of computer, high-powerly bring new problem to heat radiation again, in order to reach better radiating effect, industry uses blower fan to replace common fan.Because usually use blower fan in requiring the big application of air mass flow, blower fan will be worked under very high rotating speed, so that enough air streams are provided.But along with the raising of rotation speed of the fan, incident noise also can increase relatively.
Please refer to Fig. 1, be the exploded view of the more traditional drum fan of industry use at present, the rotation system of described blower fan is located in the shell.Described shell comprises bellows 30, and described bellows 30 comprise that 20, one stators in a bottom 40 and the bottom 20 of described bellows are made into integration, and rotor 10 pivot sleeve are located on the described stator 40, and a flabellum group 50 is sheathed on the described rotor 10.Described rotor 10 can drive described flabellum group 50 and rotate synchronously.Described flabellum group 50 comprises an intussusceptum 60, upper limb 80, lower edge 90, and some flabellums 70, described intussusceptum 60 is positioned at the center of described flabellum group 50, described flabellum 70 is positioned at the periphery of described flabellum group 50, and fixing by described upper limb 80 and described lower edge 90.By the blower fan monomer is carried out the measurement of noise and vibration, and the field observation of experimentation, judge that the vibration of fan electric fan has produced noise.
Noise when therefore how effectively to control the blower fan high speed rotating is the target of the required effort of present fan design.
[summary of the invention]
In view of above content, be necessary to provide a kind of blower fan, the noise that produces during with effective reduction fan high speed rotating.
A kind of blower fan, comprise a flabellum group, described flabellum group comprises some flabellums, a upper limb and a lower edge, described flabellum is positioned at the periphery of described flabellum group, and fixes by described upper limb and lower edge, is provided with strengthening rib between wherein per two flabellums, strengthening the mechanical structure of described flabellum group, thereby reduce the shock momentum of flabellum.
Compare prior art, when described low noise blower fan ran up, described strengthening rib had reduced the vibratory output of flabellum, reduced to vibrate the effect that reduces noise thereby reach.
[brief description of drawingsfig]
The present invention is further illustrated in conjunction with embodiment with reference to the accompanying drawings.
Fig. 1 is the exploded view of traditional drum fan.
Fig. 2 is the exploded view of the preferred embodiment of blower fan of the present invention.
Fig. 3 is the enlarged view of strengthening rib in the flabellum group of preferred embodiment of blower fan of the present invention.
[embodiment]
See also Fig. 2, the exploded view of blower fan preferred embodiment of the present invention, a blower fan comprises 200, one stators 300 of 100, one rotors of a flabellum group and a shell 400.
Described shell 400 comprises bellows 410, described flabellum group 100, and described rotor 200 and described stator 300 all are installed in the described bellows 410.
Described bellows 410 comprise a bottom 411, and described stator 300 is made into integration with described bottom 411.Described rotor 200 pivot sleeve are located on the described stator 300.Described flabellum group 100 is sheathed on the described rotor 200.
See also Fig. 3, described flabellum group 100 comprises an intussusceptum 110, ring-type upper limb 120, ring-type lower edge 130, some flabellums 140 and some strengthening rib 150, described intussusceptum 110 is positioned at the center of described flabellum group 100, described flabellum 140 is positioned at the periphery of described flabellum group 100, and fixing by described upper limb 120 and described lower edge 130.Have a bar shaped arcuation strengthening rib 150 between per two flabellums 140, in order to strengthening the mechanical strength of described flabellum group 100, thereby reduce the shock momentum of flabellum.Described each strengthening rib 150 interconnects by flabellum 140, forms an annulus, and this annulus and described upper limb 120, lower edge 130 are donut.
When described low noise blower fan ran up, described strengthening rib had reduced the vibratory output of flabellum, reduced to vibrate the effect that reduces noise thereby reach.
