High-speed rail permanent magnet motor additional heat circuit enhanced cooling structure based on heat pipe

The invention discloses a high-speed rail permanent magnet motor additional heat circuit enhanced cooling structure based on a heat pipe. The motor comprises a water-cooling casing, a stator core, a stator winding, a heat pipe, a circumferential communicating vessel, a mounting groove and heat-conducting gel, a cooling water channel is arranged in the water-cooling machine shell; a containing cavity is defined by the stator winding, the stator iron core and the water-cooling machine shell. The heat-conducting gel is filled in the accommodating cavity, and the accommodating cavity is filled with a solid-solid phase change material; mounting grooves are formed in the two ends of the water-cooling machine shell. The condensation section of the heat pipe is assembled in the mounting groove of the water-cooling machine shell and extends into the cooling water channel to be in direct contact with cooling water; the evaporation section of the heat pipe penetrates through the heat-conducting gel and extends into the
