Patent ID: 8648462

Claim:
A semiconductor power module comprising: a semiconductor element having a first electrode on a front surface and a second electrode on a back surface thereof; a first heat pipe having a first region at one end of the first heat pipe, the one end of the first heat pipe being electrically connected to one of the first and second electrodes of the semiconductor element, the first heat pipe further having a second region at an other end thereof; a second heat pipe having a first region at one end of the second heat pipe, the one end of the second heat pipe being electrically connected to the other of the first and second electrodes of the semiconductor element, the second heat pipe further having a second region at an other end thereof, wherein the first region of the first heat pipe and the first region of the second heat pipe together sandwich the semiconductor element therebetween; a cooling fin sandwiched between the second region of the first heat pipe and the second region of the second heat pipe; and a first insulating plate surrounding the semiconductor element in the first regions to regulate an arrangement position of the semiconductor element, wherein at least one of the first and second heat pipes has a positioning projection for providing positioning with respect to the first insulating plate, and the first insulating plate has a positioning hole for housing therein the positioning projection of the at least one of the first and second heat pipes.
