The invention relates to a heat management system and method for a range-extended vehicle. The heat management system for the range-extended vehicle comprises a range extender cooling loop and a heat pump air conditioner loop which are connected through a plate heat exchanger. The heat pump air conditioner loop is used for providing a refrigerating and/or heating function for the extended-range vehicle and comprises a gas-liquid separator, a compressor, an external condensation evaporator, a first electronic expansion valve one-way valve assembly, a second electronic expansion valve one-way valve assembly, an internal condensation evaporator and a power battery pack. The second end of the external condensation evaporator is connected with the second end of the internal condensation evaporator through the first electronic expansion valve one-way valve assembly, the four-way pipe, the fourth proportional three-way valve and the second electronic expansion valve one-way valve assembly in sequence. According to the extended-range vehicle, by installing the extended-range vehicle heat management system architecture, waste heat isolation of the range extender during refrigeration is achieved, the waste heat transfer and utilization efficiency during heating is improved, and the endurance mileage and the use experience in extreme environments such as severe cold or intense summer heat are improved.

    本申请涉及一种增程式车辆热管理系统及方法,增程式车辆热管理系统包括通过板式换热器相连的增程器冷却回路和热泵空调回路;热泵空调回路用于为增程式车辆提供制冷和/或制热功能,包括气液分离器、压缩机、外置冷凝蒸发器、第一电子膨胀阀单向阀组件、第二电子膨胀阀单向阀组件、内置冷凝蒸发器、动力电池组;外置冷凝蒸发器的第二端依次通过第一电子膨胀阀单向阀组件、四通管、第四比例三通阀、第二电子膨胀阀单向阀组件与内置冷凝蒸发器的第二端连接。增程式车辆通过安装该增程式车辆热管理系统架构,实现了在制冷时的增程器废热隔离,提高了在制热时的余热转移利用效率,改善了在严寒或者酷暑等极端环境下的续航里程和使用体验。
