Abstract

The invention belongs to the technical field of new energy vehicles, in particular to a heat management system for a new energy vehicle and the new energy vehicle, and adopts the technical scheme that the heat management system comprises a heat source assembly, an assembly, an assembly heat dissipation system, a first heat collection system, a battery pack heat dissipation system and an engine heat dissipation system, the assembly heat dissipation system comprises an evaporator, a first heating core, a blowing fan, a mixer, a filter, a cooling box, a condenser, a first three-way valve and an electromagnetic valve, and the evaporator and the first heating core are both communicated with the mixer. And the battery pack heat dissipation system and the engine heat dissipation system share the cooling box, so that pipeline arrangement is simple, the structure is simplified, waste heat of the engine controller, the generator and the engine is effectively recycled, energy consumption is reduced, and the cruising ability of the automobile is enhanced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a thermal management system for new energy vehicles and the new energy vehicles. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four types Hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, other new energy vehicles, etc. Unconventional vehicle fuels refer to fuels other than gasoline, diesel, natural gas, liquefied petroleum gas, ethanol gasoline, methanol, and dimethyl ether , the definition of new energy vehicles: different countries have different formulations, which are usually called "low pollution vehicles" in Japan. Popularization Action Plan", the plan refers to low-p...
