Stator for rotating electric machine and cooling structure for stator

A stator for a rotating electric machine, the stator comprising:

• a stator core having a first end and a second end in an axial direction;
• a coil having coil ends each projecting outward from a corresponding one of the first end and the second end, the coil being attached to the stator core;
• cooling jackets each attached to a corresponding one of the first end and the second end of the stator core so as to house a corresponding one of the coil ends in each cooling jacket, the cooling jackets allowing cooling oil to flow therethrough;
• a plurality of introduction parts that introduce the cooling oil into the cooling jackets;
• and
• a plurality of discharge parts that discharge, from the cooling jackets, the cooling oil that has cooled the coil ends,
• each of the coil ends including a plurality of first portions and a plurality of pairs of second portions, the plurality of first portions extending parallel to an end surface of the stator core in the axial direction, each pair of the plurality of pairs of second portions being connected to both ends of a corresponding one of the plurality of first portions in a direction in which the plurality of first portions extend, the plurality of pairs of second portions extending in a direction parallel to the axial direction,
• each of the cooling jackets including an inner circumferential wall and an outer circumferential wall facing each other in a direction parallel to a radial direction of the stator core,
• the plurality of introduction parts being provided on the outer circumferential wall to be aligned in a circumferential direction of the stator core,
• the plurality of discharge parts being provided on the inner circumferential wall to be aligned in the circumferential direction of the stator core.
