The invention provides a heat dissipation system of an extended-range electric vehicle and a control method thereof, which belong to the field of extended-range vehicle control. The heat dissipation system comprises an electronic water pump, a first branch, a second branch and a radiator which are sequentially connected in series. The first branch comprises an electronic supercharger water channeland an intercooler water channel which are connected in parallel, a first temperature sensor and a second temperature sensor are arranged on the upstream and the downstream of the first branch respectively, and the second branch comprises a generator controller water channel, a generator water channel, a driving motor controller water channel and a driving motor water channel which are connected.A control valve is further arranged on the upstream of the electronic water pump and comprises a first valve port, a second valve port and a third valve port, the first valve port is connected with the electronic water pump, a water channel between the second branch and the radiator is connected with the second valve port, and the third valve port is connected with a downstream water channel of the radiator. The heat dissipation system is high in integration level, the cost can be reduced, and the space can be saved.
