Abstract
The invention discloses a fan assembly, which comprises two fans, wherein each fan comprises a framework and an impeller arranged in the framework; the two frameworks are connected with each other; the two impellers rotate toward opposite directions; and the fan assembly also comprises a plurality of rigid rods which pass through and are connected with the frameworks of the two fans. According to the fan assembly, the rigid rods are connected with the two fans with opposite rotating directions, and the opposite exciting forces generated by the two fans are mutually counteracted through relatively high force transfer performance of the rigid rods, so that vibration is reduced.
Description
Technical field
The present invention relates to a kind of combination of fans.
Background technique
At electronic product, in server, electronic component has occupied most space, has formed the very big distinguished and admirable impedance of system, has hindered radiating efficiency.Therefore adopt the mode of two fans series connection counter-rotating to increase blast through regular meeting, successfully to take away heat.Yet the vibratory output that serial fan produced also increases thereupon.
Summary of the invention
Seeing that more than, be necessary to provide a kind of combination of fans that can reduce vibration.
A kind of combination of fans; Comprise two fans, each fan comprises that a framework and is installed in the impeller in this framework, and this two framework interconnects; The direction of rotation of this two impeller, this combination of fans also comprise some rigid rods that pass and connect the framework of this two fan.
Compare existing technology, said fans combination is connected and fixed on the fan of two switched in opposite with rigid rod, the transmission performance of the higher power through rigid rod, and the excitation force in the opposite direction that this two fan is produced is repealed by implication, thereby reduces vibration.

Embodiment
Please with reference to Fig. 1, the preferred embodiments of combination of fans 10 of the present invention comprises one first fan 20, one second fan 30, four rigid rods 50 and eight cushions 60.
This first fan 20 comprises a framework, and this framework comprises that a main body 21 cylindraceous reaches the outward extending plate body 25 of two ends difference by this main body 21.Be equiped with an impeller 23 in this main body 21.Each plate body 25 contiguous four drift angle place is provided with a through hole 252 respectively, and wherein a plate body 25 contiguous each through hole 252 outwards vertically extend a grab 254.
The structure of the structure of this second fan 30 and this first fan 20 is roughly the same, also comprises the framework that an impeller 33 and is made up of a main body 31 and two plate bodys 35.Each plate body 35 contiguous four drift angle place is provided with a through hole 352 respectively, and wherein each through hole 352 place of a plate body 35 also are provided with a draw-in groove 355.
Each cushion 60 roughly is cuboid shape, is processed by rubber material.Extend to one second adjacent side 62 one first side 61 of each cushion 60, and outwards be convexly equipped with several projections 613 in this first side 61.These 62 middle parts, second side outwards are convexly equipped with a round table-like projection 623.Each cushion 60 with the relative rib places in this first side 61 and second side 62 form one be through to these cushion 60 two ends cross section be the catching groove 64 of " C " shape.Some grooves 65 are offered to this catching groove 64 respectively in two adjacent sides of this catching groove 64, to increase the elastic deformation coefficient of this cushion 60.
Please, when assembling this combination of fans 10, at first four grabs 254 of this first fan 20 are placed in four draw-in grooves 355 of this second fan 30 respectively, thereby this first fan 20 is connected with this second fan 30 with reference to Fig. 2 and Fig. 3.This first fan 20 is consistent with the blowing direction of second fan 30, but the direction of rotation of impeller 23,33.Through hole 252 on two plate bodys 25 of this first fan 20 is the corresponding through hole 352 on two plate bodys 35 of this second fan 30 respectively.Then these four rigid rods 50 are inserted the through hole 252 of this first fan 20 and the through hole 352 of this second fan 30 respectively, this first fan 20 further is connected with second fan 30.At last install this cushion 60 respectively in the part of each rigid rod 50 between two plate bodys 35 of the part between two plate bodys 25 of this first fan 20 and this second fan 30; The catching groove 64 of each cushion 60 is fastened with corresponding rigid rod 50, and first side 61 of cushion 60 and second side 62 are all towards the first corresponding fan 20 or the outside of second fan 30.
When these combination of fans 10 runnings, the direction of rotation of the impeller 23,33 of this first fan 20 and this second fan 30, and then produce excitation force in the opposite direction.These four rigid rods 50 run through the Si Jiaochu of the framework that connects this first fan 20 and second fan 30; Because rigid rod 50 has the transmission performance of higher power, this first fan 20 and the excitation force in the opposite direction that this second fan 30 produces are repealed by implication.In addition, owing on these rigid rods 50 cushion 60 is housed, can plays the effect of absorbing, vibration isolation, thereby can further reduce vibration.
In other embodiments, this combination of fans 10 can not comprise these cushions 60, and only relies on these rigid rods 50 to reduce vibration.
