PROBLEM TO BE SOLVED: To provide an electric power conversion system which enables improvement of the efficiency of cooling an electronic component with a refrigerant.SOLUTION: An electric power conversion system includes: an electronic component 2 forming part of a power conversion circuit; and a cooler 2 including a cooling space 31 for circulating a liquid refrigerant so that the refrigerant contacts with the electronic component 2. The cooler 3 has: a refrigerant introduction port 32 for introducing the refrigerant into the cooling space 31; a refrigerant discharge port 33 for discharging the refrigerant from the cooling space 31; and an air-bleeding part 34 for bleeding air from the cooling space 31. The air-bleeding part 34 is provided above the refrigerant introduction port 32, the refrigerant discharge port 33, and a lower end part 21 of the electronic component 2 disposed in the cooling space 31.SELECTED DRAWING: Figure 1 |
