 a tobacco medium portion;   a filter portion disposed to be spaced apart from the tobacco medium portion; and   a tubular cooling portion disposed between the tobacco medium portion and the filter portion, wherein the tubular cooling portion comprises a body with a cooling material.   
     
     
         2 . The aerosol-generating article of  claim 1 , wherein the cooling material comprises activated carbon. 
     
     
         3 . The aerosol-generating article of  claim 2 , wherein the activated carbon has a particle size in a range of 20 to 100 mesh. 
     
     
         4 . The aerosol-generating article of  claim 2 , wherein the activated carbon has a surface area in a range of 600 to 3,000 m 2 /g. 
     
     
         5 . The aerosol-generating article of  claim 1 , wherein the cooling material is uniformly disposed in the tubular cooling portion along a longitudinal direction of the tubular cooling portion. 
     
     
         6 . The aerosol-generating article of  claim 1 , wherein the cooling material is non-uniformly disposed in the tubular cooling portion along a longitudinal direction of the tubular cooling portion. 
     
     
         7 . The aerosol-generating article of  claim 6 , wherein a concentration of the cooling material in the tubular cooling portion at an inlet side of the tubular cooling portion adjacent to the tobacco medium portion is greater than at an outlet side of the tubular cooling portion adjacent to the filter portion. 
     
     
         8 . The aerosol-generating article of  claim 6 , wherein a concentration of the cooling material in the tubular cooling portion at an inlet side of the tubular cooling portion adjacent to the tobacco medium portion is less than at an outlet side of the tubular cooling portion adjacent to the filter portion. 
     
     
         9 . The aerosol-generating article of  claim 6 , wherein a concentration of the cooling material at a central region of the tubular cooling portion is greater than at opposite end regions of the tubular cooling portion. 
     
     
         10 . The aerosol-generating article of  claim 6 , wherein a concentration of the cooling material at a central region of the tubular cooling portion is less than at opposite end regions of the tubular cooling portion. 
     
     
         11 . The aerosol-generating article of  claim 1 , wherein the tubular cooling portion comprises a cellulose acetate tow. 
     
     
         12 . The aerosol-generating article of  claim 1 , wherein the tobacco medium portion comprises a plurality of segments. 
     
     
         13 . The aerosol-generating article of  claim 12 , wherein at least one of the plurality of segments comprises a tobacco medium. 
     
     
         14 . An aerosol-generating device comprising:
 a heater configured to heat at least a portion of an aerosol-generating article comprising a tobacco medium portion, a filter portion disposed to be spaced apart from the tobacco medium portion, and a tubular cooling portion disposed between the tobacco medium portion and the filter portion, wherein the tubular cooling portion comprises a body with a cooling material;   a power supplier configured to supply power to the heater; and   a controller configured to control the power supplied to the power supplier.   
     
     
         15 . The aerosol-generating device of  claim 14 , further comprising an aerosol generator configured to generate an aerosol by heating a liquid composition,
 wherein the aerosol generated by the aerosol generator is introduced into the aerosol-generating device.   
     
     
         16 . The aerosol-generating device of  claim 14 , wherein the cooling material comprises activated carbon. 
     
     
         17 . The aerosol-generating device of  claim 14 , wherein the cooling material is uniformly disposed in the tubular cooling portion along a longitudinal direction of the tubular cooling portion. 
     
     
         18 . The aerosol-generating device of  claim 14 , wherein the cooling material is non-uniformly disposed in the tubular cooling portion along a longitudinal direction of the tubular cooling portion. 
     
     
         19 . The aerosol-generating device of  claim 18 , wherein a concentration of the cooling material in the tubular cooling portion at an inlet side of the tubular cooling portion adjacent to the tobacco medium portion is greater than at an outlet side of the tubular cooling portion adjacent to the filter portion. 
     
     
         20 . The aerosol-generating device of  claim 18 , wherein a concentration of the cooling material in the tubular cooling portion at an inlet side of the tubular cooling portion adjacent to the tobacco medium portion is less than at an outlet side of the tubular cooling portion adjacent to the filter portion.
