[0002] At present, new energy vehicles are developing rapidly, but space layout is still a big problem in the design of new energy vehicles, especially the cabin space. In order to better improve energy utilization, designers have to collect the energy available in the whole vehicle and develop a series of energy-saving solutions such as waste heat utilization and heat pump systems. This will also introduce more complex design circuits and more parts, which will put greater pressure on the already cramped cabin space. Therefore, the integrated design of parts is increasingly valued and has more and more applications.

[0003] The vehicle body in the prior art includes three sets of coolant circulation circuits: a battery cooling circuit, a motor electronic control cooling circuit and a functional circuit, and 2 to 3 expansion kettles are required. For example, in the Chinese patent literature, a hybrid vehicle integrated thermal management system disclosed on August 14, 2020 with patent number CN202010241902X includes: a motor circuit, a battery circuit and a four-way valve, and the motor circuit and the battery circuit are connected in parallel through the four-way valve; the motor circuit includes: a first expansion kettle, a first water pump, a charger and a motor connected in series through a coolant pipeline in sequence, the outlet end of the motor is connected to the first inlet end of the four-way valve, and the first outlet end of the four-way valve is connected to the inlet end of the first expansion kettle; the battery circuit includes: a second expansion kettle, a second water pump and a battery pack connected in series through a coolant pipeline in sequence, the outlet end of the battery pack is connected to the second inlet end of the four-way valve, and the second outlet end of the four-way valve is connected to the water inlet end of the second expansion kettle.

[0004] In order to improve the integration of the kettle, those skilled in the art have conducted research and improvements thereto.

[0005] For example, in the Chinese patent literature, patent number CN2020104795569 disclosed on December 3, 2021, an integrated kettle assembly and thermal management system, the integrated kettle assembly includes a kettle base and an integrated block, the integrated block is fixedly arranged on the kettle base, a part of the integrated block is configured as the valve body of the electronic water valve, the kettle base is provided with a liquid storage cavity for storing cooling medium, the liquid storage cavity includes a first chamber and a second chamber which are independent of each other, the kettle base is provided with a water outlet interface connected to the second chamber, the valve body is provided with a liquid replenishment interface connected to the internal flow channel of the valve body, and the liquid replenishment interface is connected to the water outlet interface and is directly connected. The disadvantage is that the application only completes the integration of the first chamber and the second chamber, the connecting pipes and valves still need to be externalized, the structure is not integrated enough, and the space occupied is large.
