Stator of an electric machine and an electric machine

An electric machine comprising a stator and a rotor rotatably supported with respect to the stator, the stator comprising:

• a stator core structure;
• a stator winding comprising a plurality of stator coils mechanically supported by the stator core structure, each of the stator coils comprising electrical conductors and a cooling tube surrounded by the electrical conductors and configured to conduct cooling fluid in a longitudinal direction of the electrical conductors;
• and
• cooling elements having heat-conductive mechanical contacts with the stator core structure, the cooling elements comprising channels configured to conduct the cooling fluid and the cooling tubes of the stator coils being connected to each other via the cooling elements, one of the cooling elements comprising
• a first pipe interface configured to receive the cooling fluid, and
• a plurality of connector pipe interfaces connected to the cooling tubes of two of the stator coils,
• another one of the cooling elements comprising
• a second pipe interface configured to deliver the cooling fluid out from the stator, and
• a plurality of other connector pipe interfaces connected to the cooling tubes of two of the stator coils.
