Patent ID: 11961784
Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a first heat sink that has a first inner surface and a first outer surface opposite to the first inner surface, and has a first through hole between the first inner surface and the first outer surface;
a second heat sink that has a second inner surface disposed with a clearance left from the first inner surface of the first heat sink, and a second outer surface opposite to the second inner surface, and has a second through hole between the second inner surface and the second outer surface;
plural semiconductor elements disposed within the clearance between the first inner surface of the first heat sink and the second inner surface of the second heat sink;
a sealing member that seals the semiconductor element within the clearance between the first inner surface of the first heat sink and the second inner surface of the second heat sink; and
a first hollow tube that provides a passage for cooling water between the first and second heat sinks, is made of metal, and connects, through the sealing member, the first through hole of the first heat sink and the second through hole of the second heat sink, wherein
the first hollow tube is positioned between the plural semiconductor elements.
