ELECTRIC MACHINE WITH IMPROVED COOLING Russian patent published in 2018 - IPC H02K1/20 H02K1/32 H02K5/20 H02K9/18 

FIELD: electricity.

SUBSTANCE: electric machine comprises a housing having a first hollow cylindrical body member in which a stator and a rotor are arranged, a second hollow cylindrical body member in which the first hollow cylindrical body member is disposed and a heat exchanger shell disposed between the first and second body members. The shell of heat exchanger has a guide member extending along the helical path around the axis of rotation, and tubes extending in the axial direction leading through the guide member. The electric machine is designed in such a way that the first cooling media may be directed in the first axial direction through the first body member, wherein the first cooling media may be directed between tubes in a helical path along the corresponding the guide member in the second, opposite the first, axial direction, and the second cooling media can be axially directed through the tube.

EFFECT: improvement of cooling.
