Power converter and railroad vehicle
View Patent ↗A power converter includes: a plurality of semiconductor devices; a heat receiving plate; and a first partition member. The semiconductor devices constitute a power conversion unit. The heat receiving plate includes a first surface supporting the semiconductor devices. The first partition member is fixed to the heat receiving plate and partitions the semiconductor devices.
1. A power converter comprising:
a plurality of semiconductor devices that constitute a power conversion unit;
a heat receiving plate that has a first surface supporting the semiconductor devices;
a first partition member that is fixed to the heat receiving plate and partitions the semiconductor devices; and
a cover that is provided such that the cover and the heat receiving plate hold the first partition member therebetween, wherein
the cover has a second groove formed thereon, and
the first partition member is fitted into the second groove and is thereby fixed to the cover.
2. The power converter according to claim 1 , wherein
the heat receiving plate has a first groove formed thereon, and
the first partition member is fitted into the first groove and is thereby fixed to the heat receiving plate.
3. The power converter according to claim 1 , further comprising
a first electrical device that is fixed to the cover on an opposite side of the semiconductor devices.
4. The power converter according to claim 1 , further comprising
a pair of second partition members that are fixed to the heat receiving plate and are provided to sandwich an entirety of the semiconductor devices therebetween.
5. The power converter according to claim 4 , further comprising
a first electrical device that is fixed to an outside of the pair of the second partition members on the first surface of the heat receiving plate.
6. The power converter according to claim 1 , further comprising
a second electrical device that is fixed to a second surface of the heat receiving plate on an opposite side of the first surface.
7. The power converter according to claim 1 , further comprising
a heat sink that cools down the heat receiving plate by cooling fluid.
8. The power converter according to claim 1 , further comprising
a protrusion that protrudes from the heat receiving plate.
9. The power converter according to claim 1 , further comprising
a heat pipe that cools down the heat receiving plate.
10. A railroad vehicle comprising the power converter according to claim 1 .

12. The power converter according to claim 11 , wherein
the heat receiving plate has a first groove formed thereon, and
the first partition member is fitted into the first groove and is thereby fixed to the heat receiving plate.
13. The power converter according to claim 11 , further comprising
a pair of second partition members that are fixed to the heat receiving plate and are provided to sandwich an entirety of the semiconductor devices therebetween.
14. The power converter according to claim 13 , further comprising
a first electrical device that is fixed to an outside of the pair of the second partition members on the first surface of the heat receiving plate.
15. The power converter according to claim 11 , further comprising
a heat sink that cools down the heat receiving plate by cooling fluid.
16. The power converter according to claim 11 , further comprising
a protrusion that protrudes from the heat receiving plate.
17. The power converter according to claim 11 , further comprising
a heat pipe that cools down the heat receiving plate.
