DYNAMO-ELECTRIC MACHINE Russian patent published in 2014 - IPC H02K9/20 F28D15/02 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering, to dynamo-electric machines with a cooling system. Dynamo-electric machine (1) includes stator (2) and rotor (3). Winding system (4) is located in slots at least of stator (2). Basically, radial heat transfer is performed by means of heat tubes (5) to end surfaces (6) of stator (2). Each heat tube has evaporation zone (19) and condensation zone (7). Evaporation zone (19) is located inside a closed cooling circuit of the dynamo-electric machine. Heat tubes have woven structure (8) in one end section of the evaporation zone and/or the condensation zone to enlarge the surface of the evaporation zone and/or the condensation zone. Woven structure (8) is heat-conducting and has the possibility of providing air flow swirling in the evaporation zone and/or the condensation zone.

EFFECT: technical result consists in improvement of heat removal without any complication of the design.
