Cooling an apparatus cabinet

Abstract

An apparatus cabinet comprising one or more equipment bays, and at least one apparatus unit emitting heat in the equipment bay, the apparatus cabinet further comprising one or more inlets for drawing cooling air into the apparatus cabinet for cooling said apparatus unit, and one or more outlets for dissipating the air used for cooling from the apparatus cabinet, and the apparatus cabinet comprising a pressurization space and one or more fans interconnected to the pressurization space for changing the air pressure in the pressurization space to be different from the air pressure in the equipment bay, and a partition for separating the equipment bay and the pressurization space at least partly from one another, the partition comprising one or more air nozzles for conveying the air between the pressurization space and the equipment bay.

1 . An apparatus cabinet comprising one or more equipment bays, and at least one apparatus unit emitting heat in the equipment bay, the apparatus cabinet further comprising one or more inlets for drawing cooling air into the apparatus cabinet for cooling said apparatus unit, and one or more outlets for dissipating the air used for cooling from the apparatus cabinet, and the apparatus cabinet comprising a pressurization space and one or more fans interconnected to the pressurization space for changing the air pressure in the pressurization space to be different from the air pressure in the equipment bay, and a partition for separating the equipment bay and the pressurization space at least partly from one another, the partition comprising one or more air nozzles for conveying the air between the pressurization space and the equipment bay.  
     
     
         2 . An apparatus cabinet as claimed in  claim 1 , wherein said one or more outlets are interconnected to the equipment bay including one or more apparatus units to be cooled.  
     
     
         3 . An apparatus cabinet as claimed in  claim 1 , wherein the pressurization space is interconnected to said one or more inlets.  
     
     
         4 . An apparatus cabinet as claimed in  claim 1 , wherein the pressurization space is interconnected to one or more outlets.  
     
     
         5 . An apparatus cabinet as claimed in  claim 1 , wherein the equipment bay is interconnected to said one or more inlets.  
     
     
         6 . An apparatus cabinet as claimed in  claim 1 , wherein the fan is placed into the pressurization space.  
     
     
         7 . An apparatus cabinet as claimed in  claim 1 , wherein the fan creates excess pressure to the pressurization space for conveying cooling air from the pressurization space to said one or more equipment bays.  
     
     
         8 . An apparatus cabinet as claimed in  claim 1 , wherein the fan creates low pressure to the pressurization space in comparison with the air used for cooling to be conveyed from the equipment bay to the pressurization space.  
     
     
         9 . An apparatus cabinet as claimed in  claim 1 , wherein the fan is placed into the lower part of the apparatus cabinet for minimizing the noise at the listening height of human beings.  
     
     
         10 . An apparatus cabinet as claimed in  claim 1  comprising a first equipment bay and a second equipment bay and a separation wall separating said equipment bays from one another, the first equipment bay being cooled using the inlet air of the fan and the second equipment bay using the outlet air of the fan.  
     
     
         11 . An apparatus cabinet as claimed in  claim 1 , wherein a partition separates the pressurization space and the equipment bay entirely from one another, thus restricting the air between the pressurization space and the equipment bay to be conveyed through nozzles.  
     
     
         12 . An apparatus cabinet as claimed in  claim 1 , wherein the nozzles can be adjusted in relation to the penetrating capacity of air.
