Therefore, how reducing the vibration & noise that fan for air cooler produces, is those skilled in the art's technical issues that need to address.
Model utility content
The purpose of this utility model is to provide a kind of fan bridge with vibration-damping function.This fan bridge effectively can weaken the vibration that fan for air cooler operationally produces, thus ensures equipment safety operation, avoids causing harmful effect to the health of staff.
Another object of the present utility model is to provide a kind of air cooling device being provided with described fan bridge.
For achieving the above object, the utility model provides a kind of fan bridge with vibration-damping function, comprise fan bridge body, comprise the vibration damping equipment for supporting described fan bridge body further, described vibration damping equipment is positioned at described fan bridge body bottom portion, and is located at described fan bridge body bottom portion for being arranged on the strong point position on air cooling platform.
Preferably, the described vibration damping equipment elastic component that comprises upper connector, lower link and be located between described upper connector and lower link.
Preferably, described elastic component is elastic caoutchouc or spring.
Preferably, described spring is helical spring or pneumatic spring.
Preferably, described upper connector is connecting plate, and described lower link is support beam.
Preferably, described vibration damping equipment is located at the bottom at described fan bridge body two ends.
Preferably, described fan bridge body is truss structure.
For realizing another object above-mentioned, the utility model provides a kind of air cooling device, comprise fan for air cooler and the fan bridge for supporting described fan for air cooler, described fan bridge is the fan bridge with vibration-damping function described in above-mentioned any one, and it is installed on air cooling platform by described vibration damping equipment.
The utility model has done further improvement on the basis of existing technology, it is provided with auxiliary vibration damping equipment in the below of fan bridge body, when equipment operation, although the blower fan that it is installed is in running or can produce vibration, but because vibration damping equipment has good endergonic function, therefore the vibrational energy overwhelming majority produced during fan operation can be absorbed by fan bridge vibration damping equipment, thus reaches the object reducing vibration.
Air cooling device provided by the utility model is provided with described fan bridge, and because described fan bridge has above-mentioned technique effect, the air cooling device being provided with this fan bridge also should possess corresponding technique effect.
Accompanying drawing explanation
Fig. 1 provides by the utility model the structural representation of a kind of embodiment of the fan bridge with vibration-damping function.
In figure:
1. fan bridge body 2. vibration damping equipment 21. upper connector 22. elastic component 23. times links
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 provides by the utility model the structural representation of a kind of embodiment of the fan bridge with vibration-damping function.
As shown in the figure, in a kind of embodiment, the main component with the fan bridge of vibration-damping function provided by the utility model is fan bridge body 1, this fan bridge body 1 is truss structure, by top-bottom chord and be located at the web member forming triangular structure between chord member and form, for supporting the blower fan (not shown) of air cooling device.
The below of fan bridge body 1 is provided with passive vibration damping equipment 2, this vibration damping equipment 2 is positioned at bottom fan bridge body 1, and be located at for being arranged on the strong point position on air cooling platform bottom fan bridge body 1, the vibration damping equipment 2 shown in figure is located at the bottom at fan bridge body 1 two ends.
Particularly, vibration damping equipment 2 is primarily of upper connector 21, lower link 23 and be located at the formations such as elastic component 22 between upper connector and lower link, wherein upper connector 21 is connecting plate, be connected with fan bridge body 1, lower link 23 is support beam, for being connected with the air cooling platform of air cooling device, elastic component 22 can be elastic caoutchouc or spring, and its medi-spring can adopt helical spring or pneumatic spring again.
Theoretical according to structure antivibration, when the dominant frequency of outside vibrating source, and the natural frequency of vibration of structural system is close or when overlapping, structure will produce larger vibration or " resonance " phenomenon.In order to reduce structural vibration, very high (the ω n> ω) or very low (ω n< ω) that the natural frequency of vibration of structure must be designed, (in formula, ω n is the intrinsic natural frequency of vibration of structure, ω is outside vibrating source frequency), natural frequency of structures is staggered the frequency of outside vibration source, reaches the object of vibration damping.
Above-mentioned fan bridge belongs to low frequency configuration, increase vibration damping equipment bottom fan bridge after, reduce the intrinsic natural frequency of vibration of fan bridge system, make it the dominant frequency away from outside vibrating source, thus realize the object of vibration damping, can equipment safety operation be ensured, avoid causing harmful effect to the health of staff.
