Description
Technical field
The utility model belongs to fan antivibration area, and in particular to the fan mounting structure of a kind of electronic equipment.
Background technique
Electronic equipment refers to be made of electronic components such as integrated circuit, transistor, electron tubes, application electric technology (packet
Include) equipment that plays a role of software, including electronic computer and the robot, numerical control or the program-controlled system that are controlled by electronic computer
System etc..
There is the web camera of a kind of high definition and ultra high-definition in the Rapid Popularization of family and Small shop in electronic equipment, promotees
Keep the NVR (network hard disk video recorder) of rear end also fast-developing towards the direction of miniaturization and high capacity, more and more desktops
Grade NVR starts to release.And minimize and also increasingly highlighted with heat dissipation problem brought by high capacity, it makes the matter worse, desktop grade
Application to the noise of system, higher requirements are also raised.Therefore, the noise reduction of fan and Vibration Absorption Designing technology start extensive
Using.
As shown in Figure 1, in the prior art, network hard disk video recorder includes the inner casing 1 and shell of two settings that are nested
6, it is equipped with the exhaust vent 7 and mounting hole for fixing 2 for fan outlet air on inner casing 1, is corresponded on shell 6 on inner casing 1
Exhaust vent 7 position at be equipped with fan frame 8.
As shown in Fig. 2, in the prior art, usually increasing rubber pad between fan 3 and the inner casing 1 of network hard disk video recorder
9, vibration damping installation is carried out to fan 3, rubber pad 9 is using the shape with exhaust vent 7 and the cooperation of mounting hole 2 on inner casing 1 (as schemed
Shape shown in right figure in 2).During installation, tapping screw 10 passes through the mounting hole 2 on inner casing 1, is then passed through on rubber pad 3 corresponding
The screw hole of position is directly attacked on fan 3 on the screw hole of corresponding position, and each fan 3 is consolidated by 4 tapping screws 10
It is fixed, after the completion of fan 3 is fixed, shell 6 is nested in the outside of inner casing 1, and the two is fixed by screw.This fixed form
There are two disadvantages, so that the noise of fan 3 can not be effectively reduced:
The first, fan 3 is contacted indeed through tapping screw 10 with inner casing 1, and tapping screw 10 becomes main vibration
The resonance of transmission path, inner casing 1 becomes main noise source.This fixed form is not completely switched off fan 3 and inner casing 1
Between " hard " contact, be only reduction of influence of the vibration of fan 3 to inner casing 1 itself, vibration still can pass through self tapping spiral shell
Nail 10 is transmitted on inner casing 1, is caused inner casing 1 to resonate and is generated noise；
The second, this fixed form is limited to the demand of material cost and installation effectiveness, and the thickness of rubber pad 9 can not be accomplished
It is too thick, therefore the gap between fan 3 and inner casing 1 is also limited, when the wind speed of fan 3 is higher, quick air-flow impinges upon outer
" screaming " sound is formed on the fan frame 8 of shell 6, generates worse influence.
Utility model content

Breeze way is downwardly extending by anchor section bottom, and the breeze way is between fan and shell.
Preferably, the upper bottom surface of the breeze way is not less than 5mm at a distance from annular groove.
For breeze way between fan and shell, the upper bottom surface of breeze way ensure that assembly relation at a distance from annular groove
After formation, there is suitable gap between fan and shell, guarantee that the outlet air of fan is unimpeded, high-speed flow is avoided to impinge upon shell
" screaming " sound is generated on body.
Preferably, the anchor section be cylindrical body, the breeze way be rotary table, the damper length direction with it is described
It is consistent to be anchored section, the short transverse of breeze way.
Preferably, the connector is screw, the installation cavity with screw fit is equipped with inside the breeze way.
Preferably, the installation cavity is being cylinder close to fan side, the diameter of the cylinder and screw it is straight
Diameter is equal.
Cylindrical diameter is set as equal with the diameter of screw, and the stability of fan assembly can be improved, avoid fan work
Displacement is generated when making.
Preferably, the width of the annular groove and shell wall thickness are adapted, the inner edge of the damper and mounting hole
