Cooling device and method for cooling a medium

Abstract

A cooling device for cooling a medium; by which a large amount of heat can be dissipated in an efficient manner. The cooling device includes: an evaporation device evaporating water; a vacuum device generating a negative pressure in an evaporation chamber of the evaporation device; a charging device including a charging chamber which is fluidically connected to the evaporation chamber of the evaporation device and which is at least partially filled with an absorption medium for absorbing the evaporated water; and a discharging device by which the water absorbed by the absorption medium can be removed from the absorption medium and released to surroundings of the cooling device.

         18 . A cooling apparatus for cooling a medium, comprising:
 an evaporation apparatus for evaporating water;   a vacuum apparatus for generating a subatmospheric pressure in an evaporation space of the evaporation apparatus;   a loading apparatus which comprises a loading space which is fluidically connected to the evaporation space of the evaporation apparatus and is at least partly filled with an absorption medium for absorbing the evaporated water;   an unloading apparatus by which the water absorbed by the absorption medium can be removed from the absorption medium and released into surroundings of the cooling apparatus.   
     
     
         19 . The cooling apparatus as claimed in  claim 18 , wherein the unloading apparatus comprises an unloading space in which the water absorbed by the absorption medium can be removed from the absorption medium, wherein the unloading space is spatially separated from the loading space of the loading apparatus. 
     
     
         20 . The cooling apparatus as claimed in  claim 19 , wherein the unloading space has a higher pressure than the loading space during cooling operation of the cooling apparatus. 
     
     
         21 . The cooling apparatus as claimed in  claim 19 , wherein the cooling apparatus comprises a transport apparatus for transporting the absorption medium from the loading space to the unloading space and/or from the unloading space to the loading space. 
     
     
         22 . The cooling apparatus as claimed in  claim 21 , further comprising at least one lock device through which the absorption medium can be transported from a subatmospheric pressure side of the cooling apparatus, to which the evaporation space and/or the loading space is assigned, to a high-pressure side of the cooling apparatus, to which the unloading space is assigned. 
     
     
         23 . The cooling apparatus as claimed in  claim 21 , further comprising at least one lock device through which the absorption medium can be transported from a high-pressure side of the cooling apparatus, to which the unloading space is assigned, to a subatmospheric pressure side of the cooling apparatus, to which the evaporation space and/or the loading space is assigned. 
     
     
         24 . The cooling apparatus as claimed in  claim 19 , further comprising a transport apparatus for transporting the absorption medium in a closed circuit. 
     
     
         25 . The cooling apparatus as claimed in  claim 18 , further comprising a water feed apparatus for feeding liquid water to the evaporation apparatus. 
     
     
         26 . The cooling apparatus as claimed in  claim 18 , further comprising at least one heat exchanger by which heat can be transferred from a medium to be cooled to the evaporation apparatus, or to water to be evaporated in the evaporation apparatus. 
     
     
         27 . The cooling apparatus as claimed in  claim 18 , wherein the absorption medium comprises salt, aqueous salt solution, silica gel, minerals, hydroxide, ionic liquid and/or zeolite or is formed by salt, aqueous salt solution, silica gel, minerals, hydroxide, ionic liquid and/or zeolite. 
     
     
         28 . The cooling apparatus as claimed in  claim 18 , further comprising at least one degassing apparatus for degassing the water to be fed to the evaporation apparatus and/or at least one degassing apparatus for degassing the absorption medium to be loaded with water. 
     
     
         29 . The cooling apparatus as claimed in  claim 18 , wherein the vacuum apparatus for generating the subatmospheric pressure in the evaporation space of the evaporation apparatus is formed by a transport device for transporting the absorption medium. 
     
     
         30 . The cooling apparatus as claimed in  claim 18 , further comprising at least one heat exchanger by which heat can be transferred from an external heat source to the absorption medium arranged in an unloading space. 
     
     
         31 . A method for cooling a medium by a cooling apparatus, comprising:
 application of subatmospheric pressure to an evaporation space of an evaporation apparatus;   introduction of liquid water into the evaporation space;   evaporation of the water in the evaporation space;   introduction of the evaporated water from the evaporation space into a loading space of a loading apparatus which is fluidically connected to the evaporation space and is at least partly filled with an absorption medium for absorbing the evaporated water;   absorption of the evaporated water by means of the absorption medium;   removal of the water absorbed by the absorption medium from the absorption medium and release of the water into surroundings of the cooling apparatus.   
     
     
         32 . The method as claimed in  claim 31 , wherein the absorption medium is, after absorption of the water, taken from the loading space and introduced into an unloading space of an unloading apparatus of the cooling apparatus. 
     
     
         33 . The method as claimed in  claim 31 , wherein to remove the water absorbed by the absorption medium from the absorption medium, the absorption medium is heated to a temperature which exceeds a temperature of the medium to be cooled by the cooling apparatus before the medium has been cooled. 
     
     
         34 . The method as claimed in  claim 31 , wherein the absorption medium is cooled after removal of the water absorbed by the absorption medium from the absorption medium and/or before introduction of the absorption medium into the loading space.
