Heat radiating component

Abstract

The present invention relates to a heat radiating component that includes plural heat radiating fins which are arranged with spaces therebetween and radiate heat from the plural heat radiating fins to air flowing through the spaces between the plural heat radiating fins. Air inflow ends of the plural heat radiating fins have such notch shapes in that alternately or cyclically different portions in an arrangement direction where the plural heat radiating fins are arranged are notched.

1 . A heat radiating component, comprising:
 a plurality of heat radiating fins which are arranged with spaces therebetween so that the heat radiating component radiates heat from the plurality of heat radiating fins to air flowing through the spaces between the plurality of heat radiating fins, the heat radiating fins having such notch shapes that portions that are at least one of alternately and cyclically different in an arrangement direction of the plurality of heat radiating fins are notched.   
   
   
       2 . The heat radiating component according to  claim 1 , wherein the plurality of heat radiating fins further have air outflow ends that also have the notch shapes. 
   
   
       3 . The heat radiating component according to  claim 1 , wherein when the ends having the notch shapes of the plurality of heat radiating fins are viewed in the arrangement direction, a gap is formed between projected portions of adjacent heat radiation fins of the plurality of heat radiation fins. 
   
   
       4 . The heat radiating component according to  claim 1 , further comprising a heat absorbing plate that absorbs heat from a heat generating component that is an object to be cooled, the plurality of heat radiating fins being arranged to stand on the heat absorbing plate. 
   
   
       5 . The heat radiating component according to  claim 4 , further comprising a heat conduction member that contacts the heat absorbing plate and penetrates the plurality of heat radiating fins to conduct heat of the heat absorbing plate to the plurality of heat radiating fins. 
   
   
       6 . The heat radiating component according to  claim 1 , further comprising a fan that generates an air flow in the spaces between the plurality of heat radiating fins. 
   
   
       7 . The heat radiating component according to  claim 6 , wherein the fan is a fan that blows air into the spaces between the plurality of heat radiating fins. 
   
   
       8 . The heat radiating component according to  claim 6 , wherein the fan is a fan that blows air out of the spaces between the plurality of heat radiating fins.
