Electric Power Convertor

摘要

An electric power converter 10 includes a flow passage FP1 formed so that cooling water can pass through while exchanging heat with semiconductor modules 51, another flow passage FP2 formed so that the cooling water can pass through while exchanging heat with a capacitor 52 and a reactor 53, and a plate-like connecting plate 200 attached in a state where a major surface thereof is disposed along a side wall 110 of a case 100. A groove 211 and a groove 221 that communicate between the flow passage FP1 and the flow passage FP2 are formed in the connecting plate 200.

主权项

1. An electric power converter comprising:
a case (100) having a housing space (SP) formed therein; a first circuit section (51), which is a part of an electric power conversion circuit (50), disposed in an upper space (SP1) of the housing space; a second circuit section, which is another part of the electric power converter circuit, disposed in a lower space (SP2) of the housing space; a first flow passage (FP1) formed so that a fluid passes through while exchanging heat with the first circuit section; a second flow passage (FP2) formed so that the fluid passes through while exchanging heat with the second circuit section; and a plate-like connecting plate (200) attached in a state where a major surface thereof is disposed along a side wall (110) of the case; wherein, connecting passages (211, 221) that communicate between the first flow passage and the second flow passage are formed in the connecting plate.
