The invention provides an electric automobile radiator cooling system, a control method thereof and an electric automobile. The cooling system comprises a water pump, a charger, a motor assembly, a radiator, a cooling fan and a whole automobile control unit. One end of the water pump is connected with the charger, the other end of the charger is connected with the motor assembly, the other end ofthe motor assembly is connected with the radiator through the third three-way valve, and the other end of the radiator is connected with the other end of the water pump through the first branch to form a circulating cooling water way. A first electronic expansion valve is arranged on the first branch; a second electronic expansion valve is arranged on the parallel pipeline; the cooling fan is usedfor cooling the radiator; the whole vehicle control unit controls the operation of the first electronic expansion valve, the second electronic expansion valve or the cooling fan by detecting the temperature in the cooling water path; according to the scheme, the temperature of heat pipe components such as the driving motor can be effectively reduced in time, meanwhile, different cooling circulation modes can be started, and the energy consumption of the whole vehicle is reduced.
