Beschreibung
Zusammenfassung:	The invention discloses a thermal management system of a plug-in hybrid electric vehicle and belongs to the technical field of hybrid electric vehicles. The thermal management system of the plug-in hybrid electric vehicle comprises a main cold circulation path, and the main cold circulation path conducts heat dissipation on an engine and a speed changing box through a main radiator. The thermal management system is characterized in that the thermal management system further comprises a warm air heating circulation path; the warm air heating circulation path is constituted by a cold circulationbranch path outlet of the engine, an electric heater, a warm air heat exchanger, a first circulation pump, a first two-way valve and a cold circulation branch path inlet of the engine in a communicating mode; and the warm air heating circulation path comprises at least a working mode of cold circulation heating of the engine during working of the engine and a working mode of heating through the electric heater during not
