Hub motor heat dissipation device

The invention discloses a hub motor heat dissipation device, and relates to the technical field of hub motors, and the hub motor heat dissipation device comprises a water tank, a water outlet pipe, a water inlet pipe, a spiral first heat exchange pipe, a first pump body and a first solenoid valve, wherein the water outlet pipe and the water inlet pipe are both communicated with the water tank; the first heat exchange pipe is arranged between the water outlet pipe and the water inlet pipe, and the first heat exchange pipe is used for being attached to a shell of the hub motor; and the first pump body and the first electromagnetic valve are connected to the water outlet pipe in series. Heat dissipation is carried out through water in the invention, compared with heat dissipation through air, the hub motor heat dissipation device is advantageous in that the heat dissipation effect is improved, the heat exchange area of the heat exchange pipes and the hub motor is increased through the design of the spiral first
