Abstract
The invention eliminates recirculation or back draft associated cooling air flows in systems that use two or more cooling fans/blowers (or other possible cooling devices). The inventive device with accomplish this by mean of an “Iris-like” in-plane device. The solution described herein is to be passive in nature (although it could be made to respond to electronic or other signals/commands/control mechanisms) and will be capable of responding to a filed fan/blower and engage at the time of fan/blower failure simply by detecting the change of pressure associated with the failed cooling device. The inventive device will reduce the space required and the cost associated with back draft damping or recirculation. In addition, the device can be retrofitted to existing systems and can be designed to be an integral part of a finger guard (a safety feature) of a cooling fan. The device will also provide acoustic advantages of more traditional back draft or recirculation as the Iris will retract completely out of the airflow during normal operation and therefore not result in the acoustic vibrations associated with many of the existing solutions.
