The invention relates to an extended-range electric vehicle cooling system waterway structure, which belongs to the technical field of vehicle engines. The extended-range electric vehicle cooling system waterway structure comprises a range extender; a cylinder body of the range extender is connected with a radiator through a pipeline; the liquid outlet of the cylinder body of the range extender, the tee joint, the fan heater, the three-way valve and the liquid inlet of the cylinder body of the range extender are connected through pipelines; the three-way valve is connected with a second liquidoutlet of the indoor heat exchanger through a pipeline and the water pump; a second liquid inlet of the indoor heat exchanger is connected with the tee joint through a pipeline; a first liquid outletof the auxiliary water tank is connected with a pipeline between a cylinder body of the range extender and the radiator, and a liquid inlet and a second liquid outlet of the auxiliary water tank arecommunicated with a pipeline between the indoor heat exchanger and the water pump. According to the waterway structure, heat generated by the range extender is used for heating the fan heater, so thatthe power consumption is effectively reduced, and the endurance mileage is increased; when the vehicle is started in a cold mode, the air conditioner heat pump system heats the range extender, and vehicle heating can be rapidly completed.

    本发明涉及一种增程式电动车冷却系统水路结构,属于汽车发动机的技术领域。本发明的增程式电动车冷却系统水路结构包括增程器,增程器的缸体与散热器通过管路连接;增程器的缸体的出液口、三通、暖风机、三通阀和增程器的缸体的进液口通过管路连接;三通阀与室内换热器第二出液口之间通过管路与水泵连接,室内换热器的第二进液口与三通之间通过管路连接;副水箱的第一出液口与增程器的缸体以及散热器之间的管路连接,副水箱的进液口和第二出液口与室内换热器与水泵之间的管路连通。本发明的水路结构利用增程器产生的热量为暖风机加热,有效减少了电量消耗,增加续航里程;车辆冷启动时,空调热泵系统为增程器加热,可快速完成热车。
