The invention discloses a hub motor double-cooling heat dissipation system. The system comprises an air cooling device and an oil cooling device, the air cooling device comprises a fan arranged in a hub motor cooling cavity and a wind wheel arranged on an automobile chassis, the wind direction of the wind wheel faces a hub motor shell, an oil guide channel is connected to an outlet of an oil injection pump of the oil cooling device, and cooling oil flows to a main heat dissipation component through the oil guide channel, then gathers into the cooling cavity and then is led to the cooling oil cylinder through an external cooling device. A temperature sensor monitors air temperature, a first pressure sensor and a second pressure sensor respectively monitor acceleration and braking states of an automobile, the fan in a cooling cavity is started during acceleration, the external wind wheel is started during braking, and an oil cooling system is started when the temperature reaches a preset threshold value. The heat dissipation effect is good, the heat dissipation mode can be adjusted according to the actual state of an automobile, the system energy consumption is low, the fan arranged in the cooling cavity can accelerate falling of cooling oil, the cooling efficiency of the oil cooling device is improved, dust and sundries can be prevented from being accumulated in the motor, and the influence on the unsprung quality is small.
