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

Claim 16:
17. 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;
a semiconductor element 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;
a first hollow tube that is made of metal and connects the first through hole of the first heat sink and the second through hole of the second heat sink;
a first water cooling jacket that has a first space connected to the first through hole of the first heat sink;
a second water cooling jacket that has a second space connected to the second through hole of the second heat sink;
a bolt that presses the second water cooling jacket toward the first water cooling jacket; and
a case through which the bolt passes.
