ELECTRICAL MACHINE STATOR WITH WATER COOLING BY FLOW COOLANT Russian patent published in 2015 - IPC H02K1/20 H02K9/20 

FIELD: electrical engineering.

SUBSTANCE: this stator comprises housing, jacket with coolant passages and magnetic core with working winding. Cooling of front parts of the latter is executed either by heat removal element winding front parts arranged between plies or by those above. Said heat removal elements are composed of cylinders with ribs on outer surface extending radially outward to contact with jackets. Every said cylinder of said hear removal elements has cavity between its inner and outer walls. Said ribs are composed of heat pipes with their ends connected to cylinder outer walls to abut tightly by their end condensation ends on said jacket. Cavity between cylinder inner and outer walls of heat pipes are intercommunicated to make a sealed system filled with working fluid of heat pipes.

EFFECT: higher reliability.
