In another embodiment, the vehicle thermal management system further comprises a second heat exchanger 36 and a motor circulation loop, the motor circulation loop comprising a third heating module and a second valve module, the third heating module comprising a motor, the battery circulation loop and the motor circulation loop being respectively connected to the second heat exchanger 36, the second valve module being switchable between at least a third state and a fourth state; when the second valve module is in a third state, the third heating module is connected with the second heat exchanger in series; when the second valve module is in the fourth state, the third heating module and the second heat exchanger are disconnected, namely, the third heating module and the second heat exchanger are not communicated. In the present embodiment, the motor circulation loop and the battery circulation loop may exchange heat through the second heat exchanger 36 to heat the power battery 41.
Specifically, in the present embodiment, the third heating module includes the third water pump 30, and the second valve module includes the three-way valve 35; the output end of the third water pump 30 is connected with an electric motor, wherein the electric motor can be a driving motor 32 or a generator 34 of the vehicle, and can be both the driving motor 32 and the generator 34, and the driving motor 32 and the generator 34 can be connected in various modes, such as series connection or parallel connection. The three-way valve 35 has a first port 1, a second port 2 and a third port 3, and the second heat exchanger 36 has a first port 1, a second port 2, a third port 3 and a fourth port 4.

The second valve module has two states, a third state and a fourth state. In the third state, the second valve module, i.e. the first port 1 and the second port 2 of the three-way valve 35, are open and the third port 3 is closed. The cooling water of the third water pump 30 takes heat away after passing through the motor 32 and/or the generator 34, flows into the second heat exchanger 36 through the three-way valve 35 to exchange heat and heat the power battery 41, and then returns to the third water pump 30. In the fourth state, the second valve module, i.e. the first port 1 and the third port 3 of the three-way valve 35, are open and the second port 2 is closed. The cooling water of the third water pump 30 takes heat away through the motor 32 and/or the generator 34 and returns to the third water pump 30 through the three-way valve 35, as shown in fig. 3.
Through the embodiment, when the heat generated by the heat exchange between the first heating module or the second heating module of the heating circulation loop and the first heat exchanger 18 is insufficient to heat the power battery 41, the temperature of the power battery 41 can be accelerated through the heat exchange between the motor circulation loop and the second heat exchanger 36, so that the heat exchange efficiency of the thermal management system is improved.
The valve modules in the first embodiment and the second embodiment are the four-way valve 15 and the three-way valve 35, respectively, and may be other valves capable of controlling the flow direction of the cooling water, so that other types of valves having the same functions as those of the valve module of the present application are also within the scope of protection of the present application.
In another embodiment, the vehicle thermal management system further comprises an air conditioning cycle. The air conditioning circulation loop and the battery circulation loop exchange heat through the third heat exchanger 27 to cool the power battery 41. Specifically, as shown in fig. 1-2, the air conditioning cycle includes a compressor 20, a condenser 21, an evaporator 25, and the like. The compressor 20 in the loop provides high-pressure refrigerant gas to the condenser 21 by compressing low-pressure steam in the evaporator, and high-pressure liquid flowing out of the condenser 21 flows through the third heat exchanger 27 to exchange heat so as to cool the power battery 41 in the hybrid system. The third heat exchanger 27 also has four ports, two of which serve as input and output terminals for connection to the air conditioning circuit and the other two ports serve as input and output terminals for connection to the battery circulation circuit. When the working environment of the battery is too high in temperature, the air conditioning circulation loop in the embodiment can realize cooling of the battery system, and the battery is ensured to work at a reasonable temperature to exert the performance of the battery.
In this application, the connections between the different components in the respective circulation circuits are ensured by pipes to communicate with each other. The connection between the two components may be either direct or indirect via a line, for example in a battery circuit the fourth port 4 of the first heat exchanger 18 is connected to the input of the fourth water pump 40 via a line, on which further components may be arranged. As shown in fig. 1-2, a heating circulation loop, a battery circulation loop, a motor circulation loop and an air conditioning circulation loop are included in the thermal management system. Therefore, on the battery system, the first heat exchanger 18, the second heat exchanger 36 and the third heat exchanger 27 are connected in series with each other. The fourth port 4 of the first heat exchanger 18 is connected indirectly to the input of the fourth water pump 40 via a pipe connection. If there is only a heating cycle and the first heat exchanger 18 in the vehicle thermal management system, the fourth port 4 of the first heat exchanger 18 is directly connected to the input of the fourth water pump 40 through a pipe connection.
In addition, other components may be provided on the piping in each circulation circuit. For example, in the pure fuel mode of the vehicle, when the first valve module, that is, the four-way valve 15, is in other states in the heating circulation loop, the thermostat 12 and the engine radiator 13 are further disposed in the pipeline to dissipate heat of the engine body 11. The motor circulation loop also comprises a DC power distribution two-in-one module 31 and a controller 33 which are respectively arranged on the pipelines of the third water pump 30, the motor 32 and the generator 34. The third port 3 of the three-way valve 35 and the second port 2 of the second heat exchanger 36 are respectively connected to the third water pump 30 for communication through a pipeline, and a motor radiator 37 can be further arranged on the pipeline to radiate heat of all parts on the motor circulation loop. In this context, the connection between the components via lines is therefore not to be understood as merely a line between the two components, and possibly also other components. All of the above are within the scope of the present application for the connection and communication of the pipeline.
