Problems solved by technology

[0004] The disadvantages of this heat dissipation system are: from the converter, to the coaxial fan of the generator, to the motor, mechanically coupled air ducts are required, and the air duct layout is difficult; the heat dissipation system of the whole vehicle cannot be considered and designed in an overall manner, and the heat dissipation cannot be intensively used Power, in a state of low efficiency and extensive dispersion
For example, for the engine, if it is shut down for a long time at low temperature, it is very d

Abstract

The invention discloses a vehicle and an electric transmission system and a vehicle cooling system thereof. The vehicle cooling system comprises a main radiator, a main water cooling device, a main fan, a plurality of auxiliary radiators and auxiliary water cooling devices, wherein the main radiator and the main water cooling device are used for cooling a first to-be-cooled object; the auxiliary radiators and the auxiliary water cooling devices are used for cooling a second to-be-cooled object; the main radiator and the auxiliary radiators are arranged on the air inlet side or the air outlet side of the main fan. According to the vehicle cooling system, each to-be-cooled object is cooled in a water-cooling heat dissipation mode, and then the main fan is comprehensively utilized to provide cooling air for each heat dissipation device, so the cooling air quantity of the main fan can be effectively utilized, water-air cooling of each to-be-cooled object can be realized, overall arrangement of a whole vehicle cooling system is facilitated, intensive heat dissipation power utilization of the whole vehicle is facilitated, and heat dissipation efficiency of the whole vehicle is improved.
