Abstract:
A heat sink capable of dissipating heat concentrating on a chip portion of a power semiconductor device module efficiently is provided. A heat sink ( 20 ) includes a heat sink body ( 21 ) in which a power semiconductor device module ( 10 ) having a plurality of power semiconductor devices ( 11 ) is placed on a cooling surface F 1  and which radiates heat generated by the power semiconductor device ( 11 ); and a heat dissipation structure portion ( 25 ) having a higher heat conductivity than the heat sink body ( 21 ) and capable of dissipating heat generated by the power semiconductor device ( 11 ), wherein the heat dissipation structure portion ( 25 ) is provided at a position overlapping the power semiconductor device ( 11 ) disposed in the power semiconductor device module ( 10 ) in a direction (Z) orthogonal to the cooling surface (F 1 ) of the heat sink body ( 21 ).

Claim (Index 3):
The heat sink according to  claim 1 , wherein the heat sink body includes a plurality of first heat radiation fins provided at a position that does not overlap the power semiconductor device disposed in the power semiconductor device module in the direction orthogonal to the cooling surface of the heat sink body on a side opposite to a side on which the power semiconductor device module is placed,\n the heat dissipation structure portion includes a plurality of second heat radiation fins provided at a position overlapping the power semiconductor device disposed in the power semiconductor device module in the direction orthogonal to the cooling surface of the heat sink body on the side opposite to the side on which the power semiconductor device module is placed, and a fin interval of the second heat radiation fins is smaller than a fin interval of the first heat radiation fins.
