The invention discloses a thermal management system for an extended-range automobile and the extended-range automobile, relates to the technical field of new energy automobiles, and aims to reasonablyutilize heat generated by a PTC and an engine, guarantee the heating efficiency and improve the energy utilization rate. The thermal management system for the extended-range automobile comprises an engine cooling loop, an air conditioner heating loop, a four-way valve and a control unit used for controlling opening and closing of the four-way valve, a water heating PTC and an air conditioner warmair core body which are connected in series are arranged in the air conditioner heating loop, and the engine cooling loop is selectively communicated with the air conditioner heating loop through thefour-way valve; and the control unit is used for controlling the on-off state of the four-way valve according to the preset temperature of the air conditioner controller, the PTC water outlet targettemperature T1 and the engine water temperature T2, so that heat generated by the engine and/or heat generated by the water heating PTC are/is output through the air conditioner warm air core body. The thermal management system for the extended-range automobile is applied to the extended-range automobile.

    本发明公开一种用于增程式汽车的热管理系统及增程式汽车,涉及新能源汽车技术领域,能够合理利用PTC和发动机产生的热量,保证加热效率的同时提升能源利用率。该用于增程式汽车的热管理系统包括发动机冷却回路、空调采暖回路、四通阀以及用于控制四通阀开关的控制单元,空调采暖回路中设有相互串联的水加热PTC和空调暖风芯体,发动机冷却回路与空调采暖回路通过四通阀选择性连通;控制单元用于根据空调控制器的预设温度、PTC出水目标温度T1和发动机水温T2控制四通阀的开关状态,使得发动机产生的热量和/或水加热PTC产生的热量通过空调暖风芯体输出。该增程式汽车应用有上述方案所提的用于增程式汽车的热管理系统。
