Fan Mounting Bracket With Vibration-Absorbing Sliding Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat dissipating devices in server systems experience adverse effects due to vibrations generated by fans, which are transferred to the server enclosure and bracket, leading to inefficiencies in heat dissipation and potential damage.
Innovation Solution
A mounting apparatus comprising a receiving bracket, a locking member, a vibration absorbing member, and a guiding member is used to mount the fan to the enclosure, where the vibration absorbing member, made of elastic materials, absorbs vibrations by sliding along a sliding slot and utilizing a buffering portion to deform and support the bracket, thereby reducing vibration transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If fans are secured to a bracket in a server system, then heat dissipation function is achieved, but vibration is generated and transferred to the server enclosure causing adverse effects
Solution Approach 1:
A vibration absorbing member is introduced as an intermediary component between the fan and the server enclosure. This member absorbs and dampens the vibration generated by the fan before it can be transferred to the enclosure, thereby eliminating the harmful vibration effect while preserving the heat dissipation function of the fan system
2Stability of the object's composition
If rigid mounting is used to secure fans, then stable mounting is achieved, but vibration is directly transferred to the enclosure
Solution Approach 1:
The mounting system transitions from a purely rigid connection to a compliant connection by incorporating a vibration absorbing member with specific material properties. The member's elasticity and damping characteristics are optimized to provide stable mounting while absorbing vibration, effectively changing the mechanical parameters of the mounting interface

AI summary
A heat dissipation device which is effectively vibration-free in relation to its host includes a fan, an enclosure, and a mounting apparatus. The mounting apparatus includes a receiving bracket for receiving the fan, a locking member, and a vibration-absorbing member slidably mounted to the enclosure. The receiving bracket has a locating member corresponding to the locating slot. The locating member is locked, and the vibration absorbing member abuts against a side of the receiving bracket, receiving and not transmitting the vibrations of a cooling fan.
