Abstract
A stator cooling device configured with a cylindrical stator main body that uses a rotation axis of a rotary electric machine as a central axis. A fixed portion is formed on an outer peripheral portion of the stator main body so as to protrude outward in a radial direction of the stator main body. A cooling medium flow passage includes an injection hole through which cooling medium is injected. The fixed portion is configured above a horizontal plane that passes through the central axis, and a peak portion that is farthest in the fixed portion from the central axis as viewed in an axial direction of the central axis. The injection hole opens toward the fixed portion above the outer peripheral portion of the stator and toward the first vertical plane side with respect to a second vertical plane that is a vertical plane that passes through the peak portion.
