PROBLEM TO BE SOLVED: To provide a power conversion device that can secure heat radiation of a reactor while securing heat radiation of other heat radiating elements.SOLUTION: A power conversion device has a container having a bottom which is opened at the front surface side thereof. The bottom wall of the container is provided with a first heat radiation part contributing to heat radiation of a reactor which forms a booster circuit directing to the outside of the container, a second heat radiation part contributing to heat radiation of a semiconductor element forming an inverter circuit, and a third heat radiation part contributing to heat radiation of a reactor forming a filter when AC power is obtained. An air channel extending vertically is provided substantially at the center of the outside of the bottom wall, and the first heat radiation and the third heat radiation are configured above the right and left sides of the second heat radiation part at the outside of the bottom wall.SELECTED DRAWING: Figure 3 |
