Universal Telescopic Louvered Panel Attachment and System for Passive Stack Effect Cooling in a Data Center

Abstract

A telescopic louvered panel and system for enhancing cold aisle and hot aisle passive stack effect cooling efficiency in a data center is provided. The panel has a panel frame with a pair of vertical side walls. Each of the side walls has a back flange portion with mounting apertures for mounting the panel frame to either one of a computer cabinet or server door. A series of horizontally telescoping blade members have opposite ends which are pivotally connecting the side walls. The blade members are capable of slidably adjusting a width dimension of the frame, and pivoting on a horizontal plane. A vertical tilt bar links the blades together so that the blades push to open and close in unison.

         6 . The system according to  claim 5 , further comprising a vertical tilt bar assembly pivotally connected to each of said blade members, said tilt bar assembly linking said blade members together so that said blades operate to open and close in unison. 
     
     
         7 . The system according to  claim 5 , wherein said computer room includes a raised floor assembly being a matrix of raised floor panels carried on a pedestal support system, said raised floor assembly defining a lower plenum and an upper plenum, and said ducting system further includes a row of air-grate floor panels capable of directing said cooling airflow from said lower plenum into said cold aisle. 
     
     
         8 . The system according to  claim 5 , wherein said air conditioning and ducting system includes a loop comprising a first ducting and a second ducting, said first ducting and said second ducting being positioned in an alternating alignment so that said first ducting is capable of supplying said cooling airflow into said cold aisle and said second ducting is capable of removing said heated airflow from said hot aisle.
