The invention provides an extended-range new energy automobile thermal management system and an automobile, the system comprises a PTC heating water loop, an electric drive loop and a refrigerant loop, and branches of the PTC heating water loop are communicated through a six-way valve; and all branches of the electric drive loop are communicated through the seven-way valve. By switching the states of the six-way valve and the seven-way valve, heat of the PTC heating water loop is used for heating the battery branch and the air conditioner branch. Meanwhile, the environment heat is absorbed by the electric drive branch, the battery cooling branch and the radiator branch. By means of the mode, all the loops are communicated with the six-way valve and the seven-way valve, the number of valves of the heat management system can be reduced, pipeline arrangement is simplified, and cost is reduced.

    本申请提供一种增程新能源汽车热管理系统及汽车,其中,系统包括:PTC加热水回路、电驱回路和冷媒回路,利用六通阀连通PTC加热水回路的各支路;利用七通阀连通电驱回路的各支路。通过切换六通阀与七通阀的状态,利用所述PTC加热水回路的热量为所述电池支路和空调支路加热;同时,利用电驱支路电池冷却支路和散热器支路吸收环境热量。通过上述方式,使各回路均与六通阀七通阀连通,能够减少热管理系统的阀的数量,简化管路布置,降低成本。
