Power conversion device
First Claim
1. A power conversion device comprising:
- a power conversion module;
a control circuit board on which a control circuit to control said power conversion module is arranged;
a heat sink serving to radiate generated heat of said power conversion module; and
a case that contains therein said power conversion module and said control circuit board;
wherein said case is divided into a module case that contains said power conversion module and a control circuit case that contains said control circuit board;
there are provided a power conversion module section in which said power conversion module and said heat sink are thermally coupled, said power conversion module is contained in said module case in such a manner that a radiator fin of said heat sink is exposed to outside, and one side of said module case is put in an open state; and
a control circuit section in which said control circuit board is contained in said control circuit case, and one side of said control circuit case is put in an open state;
and respective opening sides of said power conversion module section and said control circuit section are opposite to each other, a heat insulating partition wall functioning to do heat rejection is inserted between the opposite portions, and then said power conversion module section and said control circuit section are coupled.

Abstract
A power conversion device is downsized by integrally constructing a power conversion module and a control circuit board. The power conversion device includes a power conversion module 11, a control circuit board 21, and a heat sink 12. A case is divided into a module case 13 and a control circuit case 23. In a power conversion module section 10, the power conversion module 11 is thermally coupled to the heat sink 12 and contained in the module case 13 with a radiator fin 12a exposed to outside, one side of the case 13 being open. In a control circuit section 20, the control circuit board 21 is contained in the control circuit case 23, one side of the case 23 being open. Opening sides of the module section 10 and the circuit section 20 are opposite each other, and between which a heat insulating partition wall 30 is inserted.
