Spring-Mounted Cooling Fan Isolation for Mobility Measurement

The patent introduces spring stacks as intermediary elements between the cooling fan and chassis. These springs serve as a mediator that allows the fan to be mounted while isolating vibrations from the measurement system. The springs provide mechanical coupling for mounting while simultaneously acting as vibration isolators, thus resolving the contradiction between effective cooling and vibration transmission.

The patent segments the mounting system into multiple independent spring elements (typically four or more spring stacks) distributed around the fan mounting area. This segmentation allows the system to maintain overall structural stability while each individual spring provides vibration isolation. The distributed spring configuration ensures that the fan remains stable for cooling purposes while vibrations are isolated from the measurement chamber.

The patent applies different mechanical properties to different parts of the mounting system. The spring stacks are designed with specific characteristics: they provide soft vertical compliance for vibration isolation in the vertical direction, while maintaining adequate lateral stiffness through their geometric configuration and material properties. This local differentiation of mechanical properties allows the system to achieve both vibration attenuation and sufficient structural support simultaneously.
