The invention provides a heat pump type integrated heat management system utilizing motor waste heat, and belongs to the technical field of electric vehicle heat management systems. Comprising a motor heat management circulation loop, a battery heat management circulation loop, a cabin heat management circulation loop and a heat pump air conditioner circulation loop. The motor heat management circulation loop mainly realizes heat dissipation of electric control parts of the motor and recovery of waste heat of the motor; the battery heat management loop mainly realizes the functions of refrigerating when the battery temperature is too high, heating the battery at low temperature and equalizing the temperature of the battery pack when the temperature is proper, so that the service life of the battery is prolonged and the charge-discharge capability of the battery is improved; the cabin heat management circulation loop is combined with the heat pump air conditioner loop to mainly achieve the heating and cooling effects of the cabin. The heat pump air conditioner can heat a refrigerant at an inlet of the compressor through the plate heat exchanger by utilizing motor waste heat at low temperature, and the energy utilization rate of the system is improved. According to the integrated heat management loop, the integrated valve is used for replacing a traditional switch valve, and the complexity and development cost of a heat management system can be effectively reduced.
