Air conditioning device for cooling air for an electronic device cabinet or the like

Abstract

This invention entails an air conditioning device ( 2 ) for cooling an electronic device cabinet or the like. It is equipped with a housing, an air supplying device ( 10 ) and a heat exchanger ( 4 ). The air supplying device ( 10 ) sucks air in from one side and conducts it through a heat exchanger ( 4 ) to a second side ( 14 ) and supplies it in radial direction to the second side ( 14 ). The heat exchanger ( 4 ) is connected so as to impact with its external or internal cooling device the heat exchangers with cooled cooling medium. The outgoing current of radially streaming air is applied to front surface of adjacent electronic device cabinets so that the air can thus be used without being substantially mixed in advance with warmer air. The air can also be sucked in by the electronic device cabinets and used for cooling without losses of efficiency levels.

1 . Air conditioning devices for cooling of air for an electronic device cabinet or the like, equipped with
 a housing having a first side, and a second side located opposite the first side,   an air supplying device and   a heat exchanger,   wherein the air supplying device sucks in air from the first side, conducts it through the heat exchangers to the second side and delivers it in radial direction to the second side,   and wherein the heat exchanger is connected with an external cooling device or with an internal cooling device impacting the heat exchangers with cooled cooling medium.   
     
     
         2 . Air conditioning device according to  claim 1 , wherein
 the air supplying device comprises a radial fan, which is extended from the second side of the air conditioning device outward and   which is arranged so as to discharge an air stream which axially enters the air conditioning device in radial direction parallel to a limiting surface of the second surface.   
     
     
         3 . Air conditioning device according to  claim 1 , equipped with a plurality of air supplying devices arranged at a distance between them at different heights. 
     
     
         4 . Air conditioning device according to  claim 3 , wherein the heat exchanger is provided with respective individually controllable heat exchanger segments at different heights. 
     
     
         5 . Air conditioning device according to  claim 1 , further equipped with a projecting frame in which is arranged the air supplying device. 
     
     
         6 . Air conditioning device according to  claim 1 , further equipped with an internal cooling device. 
     
     
         7 . Air conditioning device according to  claim 1 , further equipped with at least one line connecting the heat exchangers with a central cooling device. 
     
     
         8 . Air conditioning device according to  claim 1 , wherein the air volume stream induced by the air supplying device is controllable. 
     
     
         9 . Air conditioning device according to  claim 8 , wherein the air volume stream induced by each air supplying device can be controlled individually. 
     
     
         10 . Air conditioning device according to  claim 8 , further equipped with at least one temperature sensor detecting temperature of air streaming in and/or streaming out at the rear side of an electronic device cabinet to be cooled, at the rear side of the air conditioning device, or at the outlet side of the heat exchanger. 
     
     
         11 . Air conditioning device according to  claim 10 , equipped with a plurality of temperature sensors which detect the temperature at different levels, wherein the detected temperatures are utilized for individual regulation of the volume of the air stream and/or of the heat exchanger segments. 
     
     
         12 . Air conditioning device according to  claim 1 , wherein the air supplying device emits cold air in a radial stream so as to move directly along a front surface of the electronic device cabinet or the like, so that the cold air does not substantially mix with warmer air prior to reaching a front surface. 
     
     
         13 . Air conditioning device according to  claim 12 , wherein the air supplying device is adjustable to curves along a front surface or front sides of the cabinets for electronic devices or the like. 
     
     
         14 . Air conditioning device according to  claim 12 , which is positioned between two cabinets for electronic devices, and wherein the air supplying device comprises a radial fan, which radial fan discharges cold air in a radial stream so as to move directly along a front surface of the two cabinets.
