       11 . The heat radiating apparatus as claimed in  claim 1 , wherein the fan unit is positioned so as to cause the airflow to flow through channels provided between the plurality of radiating fins of the respective radiating portions.  
   
   
       12 . The heat radiating apparatus as claimed in  claim 1 , wherein a base plate of at least one of the radiating portions is configured to contact with a heat source.  
   
   
       13 . The heat radiating apparatus as claimed in  claim 1 , wherein a cross section of the radiating fins of at least one of the radiating portions is in the shape of a [ providing a gap between the plurality of radiating fins when the respective plurality of radiating fins are attached to one another.  
   
   
       14 . The heat radiating apparatus as claimed in  claim 1 , wherein the at least one heat pipe is in the shape of a U.  
   
   
       15 . The heat radiating apparatus as claimed in  claim 1 , wherein the at least two radiating portions are formed of at least one of copper or aluminum.  
   
   
       16 . A heat radiating apparatus, comprising: 
 a first radiating portion comprising a base plate in contact with a heat source and a plurality of radiating fins provided on the base plate configured to radiate heat;    at least one heat pipe having one end thermally connected to the base plate and configured to transfer heat away from the first radiating portion;    a second radiating portion thermally connected to the other end of the at least one heat pipe and configured to transfer heat away from the second radiating portion, the second radiating portion comprising a plurality of radiating fins configured to radiate heat;    a fan unit installed adjacent the first and second radiating portions and configured to cause ambient air to pass through the first and second radiating portions and be discharged outside thereof.
