Vibration-proof structure of series fan

Abstract

The present invention relates to a vibration reducing structure of a series connected fan. The series connected fan at least comprises two fan frames, a vibration reducing component is arranged between the surfaces at the vibration reducing combination of the fan frames, and the vibration reducing component must be made of elastic material of vibration absorbing and vibration damping. When the impeller rotators inside the fan frame run, the base frequency of the vibration of the two fan rotators can be damped and absorbed by the vibration reducing component of the present invention, thereby avoiding serious resonance effect and the vibration noise caused by mutual affect, and maintaining the optimum effect and the service life of the system.

Description

technical field [0001] The invention relates to a vibration-proof structure of a serial fan, in particular to a vibration-proof structure of a serial fan which can solve the resonance effect caused by the operation of more than two fan wheel rotors after multiple fans are connected in series. Background technique [0002] The static pressure generated by two or more fans connected in series can be doubled under the condition of zero air volume, and adding one more fan in series can increase the air volume in a system with higher static pressure, so the series fan can reach the maximum for a high-impedance system. Good cooling effect. [0003] The fan will definitely vibrate when it is running, but the strength and weakness are different. Generally speaking, the higher the static pressure and the larger the fan, the more serious the vibration will be, and the vibration will not only produce noise, but also reduce system stability. , leading to premature fatigue and aging of ...

AI Technical Summary

Problems solved by technology

[0007] 1. After the two fan frames 10 are connected in series, the resonance situation is serious: the design principle of the motor torque operation itself will inevitably produce vibration, especially for the series fan, when the fan wheel rotors inside the two fan frames 10 rotate at the same time, the vibration of the second fan wheel rotor Under the mutual influence of the fundamental frequency, the two fan frames 10 will have a serious resonance effect, and this resonance effect will be directly transmitted and affect the system, resulting in the system not being able to exert its best performance

[0008] 2. The life of the system is shortened by the resonance effect: the resonance effect will not only affect the efficacy of the entire system, but when the system is in a vibrating environment for a long time, it will also accelerate the premature fatigue and aging of the contacts of its internal electronic components, shortening the life of the system

[0009] 3. Serious vibration and noise: the resonance effect is also accompanied by huge noise, which has a great impact on the overall noise value evaluation of the system
