According to the new energy vehicle heat dissipation system and a heat dissipation control method thereof, systematic technical cost reduction is carried out on the heat dissipation system, and meanwhile partition control over the heat dissipation power of the battery and the motor can be achieved. The problem that an existing cooling system is high in cost is solved. The system comprises a main controller, two heat dissipation boxes, two water pumps, a heat dissipation fan, a first heat dissipation box, a first water pump and a motor of a new energy vehicle which are connected in sequence toform a first heat dissipation loop; the second heat dissipation box, the second water pump and the electricity of the new energy vehicle are sequentially connected to form a second heat dissipation loop; the heat dissipation fan dissipates heat of the first heat dissipation box and the second heat dissipation box; a temperature sensor of the motor sends a first temperature signal to the main controller; a temperature sensor of the battery sends a second temperature signal to the main controller; and the main controller sends a start-stop signal and/or a control signal to the first water pump control unit, the second water pump control unit and the cooling fan control unit.
