The invention discloses a double-motor parallel radiating system of a new energy automobile and a radiating method. The double-motor parallel radiating system comprises a front driving motor cooling pipeline and a rear driving motor cooling pipeline, wherein the front driving motor cooling pipeline comprises a front driving motor, the rear driving motor cooling pipeline comprises a rear driving motor, and the front driving motor cooling pipeline and the rear driving motor cooling pipeline are in parallel connection and share a motor radiator assembly. The rear driving motor cooling pipeline further comprises a first pump and a first switch valve. The front driving motor cooling pipeline further comprises a second pump and a second switch valve. The first switch valve, the second pump and the motor radiator assembly are connected with a first three-way connector, and the second switch valve, the motor radiator assembly and the rear driving motor are connected with a second three-valve connector. The front driving motor and the rear driving motor radiate jointly, the volume and weight of cooling liquid are decreased. In addition, two independent circulating pipelines do not need to be arranged, a structure and a mounting support which are required by mounting a cooling liquid pipeline are further omitted, and the weight and cost of the automobile are reduced.
Description
technical field [0001] The invention relates to the technical field of automobiles, and more specifically, to a dual-motor parallel cooling system and cooling method for new energy vehicles. Background technique [0002] Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are considered to be an important way to solve the energy crisis and environmental degradation. Hybrid vehicles take into account the advantages of pure electric vehicles and traditional internal combustion engine vehicles at the same time. On the premise of meeting the requirements of vehicle power and mileage, it effectively improves fuel economy and reduces emissions. It ...
