TELECOMMUNICATIONS SYSTEM COOLING FAN INCORPORATING A COMPACT VIBRATION ISOLATOR

摘要

The present invention provides a cooling fan assembly for use in a telecommunications system, including: a cooling fan; a housing; a rigid pin disposed through the housing an into a mounting hole manufactured into the cooling fan; a vibration isolator disposed about the rigid pin within the mounting hole; and a washer disposed about the rigid pin between the cooling fan and the housing. The vibration isolator is a cylindrical vibration isolator. The vibration isolator is made of a polymeric vibration damping material. The washer is made of material with a low coefficient of friction. The vibration isolator is operable for damping vibrations emanating from the cooling fan. The washer is operable for allowing some movement of the cooling fan perpendicular to the rigid pin.
