Abstract:
1. A stator cooling device, comprising: a cylindrical stator main body that uses a rotation axis of a rotary electric machine as a central axis; a fixed portion that 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, and fixes the stator main body to a case that houses the rotary electric machine; and a cooling medium flow passage into which a cooling medium is supplied and that includes an injection hole through which the cooling medium is injected, wherein the fixed portion is disposed 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 is disposed at a position displaced from a first vertical plane that is a vertical plane that passes through the central axis, and the injection hole opens toward the fixed portion above the outer peripheral portion of the stator main body 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.
