The invention discloses a heat dissipation management system for a hub motor of an electric automobile. The system comprises a front wheel heat dissipation circulation loop, a rear wheel heat dissipation circulation loop and a controller. The front wheel heat dissipation circulation loop comprises three different heat dissipation circulations, and the rear wheel heat dissipation circulation loop comprises three different rear wheel heat dissipation circulations. The controller judges the heat dissipation requirement through the obtained motor temperature signal, selects a working mode, generates a control signal, outputs the control signal to the electromagnetic valve, the heat dissipation fan and the water pump, and selects the corresponding heat dissipation circulation by controlling the on-off of the electromagnetic valve. The heat dissipation management effect of the four-wheel hub motor is achieved by controlling the rotating speed of the water pump and adjusting the heat dissipation amount through the heat dissipation fan, and great significance is achieved for improving the heat dissipation management efficiency of the four-wheel hub motor.
