The invention aims to provide an integrated power battery thermal management system with cooling and fire extinguishing functions. A compressor, a condenser, a dry filter, a refrigeration electromagnetic valve, a capillary tube and an evaporator are sequentially connected to form a compressor unit refrigeration unit; a manual valve and a liquid spraying electromagnetic valve are led out from the front of the refrigerating electromagnetic valve to form a spraying branch; a manual valve and a thermal electromagnetic valve are led out from a pipeline between the compressor and the condenser to form a thermal bypass branch; a first three-way connecting valve, a water absorption filter and a regulating valve are connected to a liquid outlet of a liquid cooling plate in the battery liquid tank to form a liquid cooling branch, and the second three-way connecting valve, the water absorption filter and the liquid return electromagnetic valve are connected to a liquid return port of the sealed battery liquid tank to form a liquid fire extinguishing branch; the circulating pump, the temperature sensor, the flow sensor, the flow regulating valve, the diaphragm valve and the heater are sequentially connected to form a liquid cooling circulating unit. Cooling and fire extinguishing functions are integrated, the space utilization rate of the system can be increased, and the safety performance of the whole thermal management system is enhanced.
