The invention relates to a cooling system for a new energy vehicle with a dual-motor driving system and the new energy vehicle. The cooling system comprises a first motor cooling system, a second motor cooling system, a first heat exchanger and a second heat exchanger. An inlet of the first motor cooling system communicates with cooling liquid outlets of the first motor and the second motor, and an outlet communicates with a cooling liquid inlet of the first motor; an inlet of the second motor oil cooling system communicates with cooling liquid outlets of the second motor and the first motor, and an outlet communicates with a cooling liquid inlet of the second motor; the first heat exchanger is communicated with the first motor cooling system and the second motor oil cooling system; the second heat exchanger is communicated with the second motor oil cooling system and the first motor cooling system. The oil viscosity of the gearbox can be reduced, and the operation efficiency of the gearbox can be improved; the first motor cooling system and the second motor oil cooling system are standby for each other, so that normal running of the vehicle is guaranteed; and the working condition requirement of forced cooling can be met.
