Summary:The utility model relates to a motor heat radiation structure, which comprises a casing, stators arranged in the casing, a rotor sleeved between the stators, a liquid cooling channel wound inside the casing and an air cooling channel used for cooling the casing, the stators and the rotor, and the liquid cooling channel is filled with cooling liquid and used for exchanging heat with the casing. The cooling of the shell is realized; the air cooling channel comprises a plurality of cooling air inlets, a rotor air cooling channel communicated with the cooling air inlets, a stator air cooling channel communicated with the rotor air cooling channel, a machine shell air cooling channel communicated with the stator air cooling channel and a cooling air outlet communicated with the machine shell air cooling channel. According to the motor heat radiation structure, radial cooling, axial cooling and rotary sealing are combined, and countercurrent flow heat exchange is realized in the axial direction. According to the ut
