The invention provides a plug-in hybrid electric vehicle cooling system, which belongs to the technical field of a vehicle. The plug-in hybrid electric vehicle cooling system aims at designing a set of integral cooling system through connecting branch pipelines and a two-position three-way valve between an engine and a motor. A No.1 branch pipeline is connected onto a cooling water pipe arranged at the upper end of the motor; a No.1 two-position three-way valve is arranged on the No.1 branch pipeline; the other end of the No.1 branch pipeline is connected onto a No.2 two-position three-way valve; the No.2 two-position three-way valve is arranged on a pipeline arranged at the upper end of the engine; a No.3 two-position three-way valve is arranged on a pipeline arranged behind a motor cooling water pump arranged at the lower end of the motor, and is connected onto a pipeline arranged under the engine cooling water pump arranged at the lower end of the engine through a No.3 branch pipeline; and the No.1 two-position three-way valve is connected with the No.3 branch pipeline through a No.2 branch pipeline. The plug-in hybrid electric vehicle cooling system has the advantages that the temperature control of the engine, the motor, a passenger cabin and a battery is considered in a unified way; the set of integral cooling system is designed; and cooling components of the engine, the motor, the passenger cabin and the battery are integrated into one system, so that the structure of the cooling system is relatively simple.
