In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.
[0049] The thermal management module 100 according to an embodiment of the first aspect of the present utility model is described below with reference to the accompanying drawings.
[0050] like Figure 1-Figure 23 As shown, the thermal management module 100 according to the first embodiment of the utility model includes: a first module 1, the first module 1 includes a first integrated board 11 and a first water pump 12, a first control valve 13 and a first heat exchanger 14 arranged on the first integrated board 11, and a flow channel 111 is formed in the first integrated board 11, so that the first water pump 12, the first control valve 13 and the first heat exchanger 14 arranged on the first integrated board 11 can be connected through the flow channel 111, that is, the first water pump 12, the first control valve 13 and the first heat exchanger 14 can be integrated on the first integrated board 11, so that the cost of the pipeline for connecting the first water pump 12, the first control valve 13 and the first heat exchanger 14 can be saved, and the structure of the first module 1 is simplified to reduce the layout difficulty and production cost of the thermal management module 100. The first water pump 12 can provide a driving force for the coolant in the flow channel 111, so that the coolant in the flow channel 111 flows in a specified direction to achieve heat exchange.
[0051] Among them, the first control valve 13 has a first state. In the first state, the first water pump 12, the first control valve 13, the first heat exchanger 14 and the flow channel 111 together constitute a first flow path. The first flow path is suitable for communicating with the heat exchange channels of the engine and the cabin heating component and forming a closed first circulation flow path. The first heat exchanger 14 is used to communicate with the heat exchange channel of the power battery. That is to say, under the control of the first control valve 13, the heat exchange channel of the engine can be communicated with the heat exchange channel of the cabin heating component through the first flow path, that is, the first flow path can form a circulating channel connected with the heat exchange channel of the engine and the heat exchange channel of the cabin heating component, so that the coolant can circulate between the first flow path, the heat exchange channel of the engine and the heat exchange channel of the cabin heating component.
[0052] The cabin heating assembly includes a heater core, which can release the heat of the coolant in the heat exchange channel of the cabin heating assembly to the passenger cabin to heat the passenger cabin. Therefore, when the coolant circulates in the first circulation path driven by the first water pump 12, the coolant can absorb the heat generated during the operation of the engine when flowing through the heat exchange channel of the engine, so that the coolant has a higher temperature. When the coolant absorbs the heat in the heat exchange channel of the engine and flows through the heat exchange channel of the cabin heating assembly, the coolant can heat the passenger cabin by releasing the heat to the heater core, so as to improve the riding experience of the people in the passenger cabin.
[0053] Furthermore, the first heat exchanger 14 is connected to the heat exchange channel of the battery at the same time. Therefore, when the coolant that absorbs heat in the heat exchange channel of the engine flows through the first heat exchanger 14, it can release heat to the coolant in the heat exchange channel of the battery to heat the power battery, so that the power battery is within a suitable temperature range to avoid the power and capacity reduction caused by the power battery being too low. In other words, the heat generated by the engine can be used to heat the passenger cabin and the power battery through the first module 1, so that the engine heat can be reused to reduce heat loss, thereby improving the heat utilization rate of the thermal management module 100.
[0054] According to the thermal management module 100 of the first aspect of the present invention, the structure of the first module 1 is simplified to reduce the difficulty of arranging and the production cost of the thermal management module 100. At the same time, the heat generated by the engine can be used to heat the passenger cabin and the power battery through the first module 1, so that the engine heat can be reused to reduce heat loss, thereby improving the heat utilization rate of the thermal management module 100.
[0055] According to some embodiments of the utility model, the first control valve 13 also has a second state and a third state. In the second state, the first water pump 12, the first control valve 13 and the flow channel 111 together constitute a second flow path, and the second flow path is suitable for communicating with the heat exchange channel of the engine and the cabin heating component and forming a closed second circulation flow path. That is, under the control of the first control valve 13, the heat exchange channel of the engine can be communicated with the heat exchange channel of the cabin heating component through the second flow path, that is, the second flow path can form a circulation channel connected with the heat exchange channel of the engine and the heat exchange channel of the cabin heating component, so that the coolant can circulate between the second flow path, the heat exchange channel of the engine and the heat exchange channel of the cabin heating component. Therefore, when the coolant circulates in the second circulation path, the heat absorbed by the coolant when flowing through the heat exchange channel of the engine can be released to the heater core to heat the passenger cabin when flowing through the heat exchange channel of the cabin heating component. At this time, the coolant does not flow through the first heat exchanger 14, so that the heater core can receive more heat generated by the engine to enhance the heating effect of the thermal management module 100 on the passenger cabin in the second state.
[0056] In the third state, the first water pump 12, the first control valve 13, the first heat exchanger 14 and the flow channel 111 together constitute a third flow path, and the third flow path is suitable for communicating with the heat exchange channel of the cabin heating component and forming a closed third circulation flow path. That is, under the control of the first control valve 13, the third flow path can form a circulation channel connected with the heat exchange channel of the cabin heating component, so that the coolant can circulate between the third flow path and the heat exchange channel of the cabin heating component. Among them, the cabin heating component usually includes a heater, and the heat exchange channel of the cabin heating component can be heated by the heater. Therefore, during the circulation of the coolant in the third circulation flow path, when the coolant flows through the heat exchange channel of the cabin heating component, it can absorb the heat generated by the heater. When the heated coolant flows through the heater core, it can release heat to the heater core to heat the passenger cabin. At the same time, when the coolant absorbs the heat of the heater and flows through the first heat exchanger 14, it can release heat to the coolant in the heat exchange channel of the battery to heat the power battery.
[0057] In other words, when the first control valve 13 is in the third state, the passenger cabin and the power battery can be heated by the heater of the cabin heating assembly without starting the engine, thereby reducing the energy consumption and loss of the engine. It should be noted that the heater of the cabin heating assembly can be an electric heater or a car heater, etc., and the type of the heater of the cabin heating assembly is not specifically limited here.
[0058] According to some embodiments of the present utility model, the flow channel 111 includes a first channel 1111, a second channel 1112, a third channel 1113, a fourth channel 1114 and a fifth channel 1115. The first control valve 13 has a plurality of valve ports, which are respectively a first valve port 131, a second valve port 132, a third valve port 133, a fourth valve port 134, a fifth valve port 135 and a sixth valve port 136. One end of the first channel 1111 and the second channel 1112 is used to connect to the heat exchange channel of the engine and the other end is connected to the first valve port 131 and the second valve port 132 respectively. The third channel 1113 is connected to the third valve port 133 and the heat exchange channel of the cabin heating component at the same time. The fourth channel 1114 is connected to the heat exchange channel of the cabin heating component, the fourth valve port 134, the fifth valve port 135 and the first heat exchanger 14. The fifth channel 1115 is connected to the first heat exchanger 14 and the sixth valve port 136. The first control valve 13 can control the connection or cutoff between the plurality of valve ports. Therefore, the first control valve 13 can be used to control the connectivity between multiple valve ports, and control the connectivity or cutoff between the first channel 1111, the second channel 1112, the third channel 1113, the fourth channel 1114, and the fifth channel 1115 to control the flow direction of the coolant in the first module 1.
[0059] Specifically, in the first state, the first control valve 13 controls the first valve port 131 and the third valve port 133 to be connected, and the second valve port 132, the fourth valve port 134, the fifth valve port 135 and the sixth valve port 136 to be connected. Therefore, the coolant flowing out of the heat exchange channel of the engine can enter the first module 1 and can enter the heat exchange channel of the cabin heating component through the first channel 1111, the first valve port 131, the third valve port 133, and the third channel 1113 in sequence, so as to release heat to the passenger cabin through the heater core; the heat exchange of the cabin heating component The coolant flowing out of the channel returns to the first module 1 and enters the fourth channel 1114. A portion of the coolant in the fourth channel 1114 flows to the fourth valve port 134 and the fifth valve port 135, and returns to the heat exchange channel of the engine through the second valve port 132 and the second channel 1112 in sequence. Another portion of the coolant in the fourth channel 1114 flows to the first heat exchanger 14 to heat the power battery, and returns to the heat exchange channel of the engine through the fifth channel 1115, the sixth valve port 136, the second valve port 132, and the second channel 1112 in sequence. At this time, the first module 1 is in the first working mode, that is, the passenger cabin and the power battery are heated by using the heat of the engine.
[0060] In the second state, the first control valve 13 controls the first valve port 131 and the third valve port 133 to be connected, and the second valve port 132, the fourth valve port 134 and the fifth valve port 135 to be connected. Therefore, the coolant flowing out of the heat exchange channel of the engine can enter the heat exchange channel of the cabin heating component through the first channel 1111, the first valve port 131, the third valve port 133, and the third channel 1113 in sequence after entering the first module 1, so as to release heat to the passenger cabin through the heater core; the coolant flowing out of the heat exchange channel of the cabin heating component returns to the first module 1 and enters the fourth channel 1114, and all flows to the second valve port 132 through the fourth valve port 134 and the fifth valve port 135, and finally returns to the heat exchange channel of the engine through the second channel 1112. At this time, the first module 1 is in the second working mode, that is, the passenger cabin is heated by using the heat of the engine.
[0061] In the third state, the first valve port 131 and the second valve port 132 of the first control valve 13 are controlled to be connected, and the third valve port 133, the fourth valve port 134, the fifth valve port 135 and the sixth valve port 136 are connected. Therefore, the coolant flowing out of the heat exchange channel of the engine enters the first module 1 and can return to the heat exchange channel of the engine through the first channel 1111, the first valve port 131, the second valve port 132 and the second channel 1112 in sequence. At the same time, the coolant flowing out of the heat exchange channel of the cabin heating component enters the first module 1. After entering the fourth channel 1114, a part of the coolant in the fourth channel 1114 flows to the fourth valve port 134 and the fifth valve port 135, and returns to the heat exchange channel of the cabin heating component through the third valve port 133 and the third channel 1113 in sequence. Another part of the coolant in the fourth channel 1114 flows to the first heat exchanger 14 to heat the power battery, and returns to the heat exchange channel of the cabin heating component through the fifth channel 1115, the sixth valve port 136, the third valve port 133, and the third channel 1113 in sequence. At this time, the first module 1 is in the third working mode, the heater of the cabin heating component is working, and the heat generated by the heater is used to heat the passenger cabin and the power battery.
[0062] In some embodiments, the first integrated board 11 includes a first cover plate 112, a first bottom plate 113 and a first flow channel plate 114. The first cover plate 112, the first bottom plate 113 and the first flow channel plate 114 are connected by welding. A plurality of grooves are formed on the opposite sides of the first cover plate 112 and the first bottom plate 113. The plurality of grooves of the first cover plate 112 and the first bottom plate 113 jointly define the flow channel 111. At the same time, the first flow channel plate 114 is arranged on the first cover plate 112. The first flow channel plate 114 can add additional flow channels 111 at the intersection of the flow channels 111 to form a spatial dislocation of the flow channels 111, thereby avoiding interference between the flow channels 111. The first cover plate 112 is away from the flow channels 111. 1 is formed with a connecting joint 115, which may be a NW16 quick-insert structure, so as to facilitate the connection of the connecting joint 115 with an external pipeline. The connecting joint 115 includes a first connecting joint 1151, a second connecting joint 1152, a third connecting joint 1153 and a fourth connecting joint 1154, wherein the first channel 1111 is communicated with the heat exchange channel of the engine through the first connecting joint 1151, the second channel 1112 is communicated with the heat exchange channel of the engine through the second connecting joint 1152, the third channel 1113 is communicated with the heat exchange channel of the cabin heating component through the third connecting joint 1153, and the fourth channel 1114 is communicated with the heat exchange channel of the cabin heating component through the fourth connecting joint 1154.
[0063] According to some embodiments of the utility model, the first water pump 12 is arranged in the third channel 1113. In the first working mode, the second working mode and the third working mode, the coolant enters the heat exchange channel of the cabin heating component through the third channel 1113 after leaving the first control valve 13 from the third valve port 133, that is, in the first working mode, the second working mode and the third working mode, the coolant will flow through the third channel 1113 and the flow direction of the coolant in the third channel 1113 is the same. Therefore, the first water pump 12 is arranged in the third channel 1113, so that the first module 1 can share the first water pump 12 in the first working mode, the second working mode and the third working mode, thereby reducing the cost of the first module 1.
[0064] According to some embodiments of the utility model, a first water injection port 116 connected to the third channel 1113 is also formed on the first integrated board 11, and a one-way valve 15 is provided between the first water injection port 116 and the third channel 1113, and the one-way valve 15 is one-way in the direction from the first water injection port 116 to the third channel 1113. Therefore, when the amount of coolant is insufficient, the coolant can be added to the third channel 1113 through the first water injection port 116, thereby avoiding the decrease in heat exchange efficiency caused by insufficient coolant. In addition, the one-way valve 15 can prevent the coolant in the third channel 1113 from flowing to the first water injection port 116, thereby avoiding waste caused by leakage from the first water injection port 116 during the circulation of the coolant.
[0065] In some embodiments, the first water inlet 116 may be connected to a first water tank for storing coolant. Therefore, when the coolant is insufficient, the coolant in the first water tank may be used to replenish the coolant in the flow channel 111 in a timely manner.
[0066] According to some embodiments of the utility model, the thermal management module 100 further includes: a mounting bracket 4 and a controller 3, the controller 3 is electrically connected to the first water pump 12 and the first control valve 13, the mounting bracket 4 includes a base 41 and a partition 42 provided on the base 41, and the first integrated board 11 and the controller 3 are respectively installed on the opposite sides of the partition 42 in the thickness direction. Therefore, through the electrical connection between the controller 3 and the first water pump 12 and the first control valve 13, the controller 3 can control the operating state of the first water pump 12 and the first control valve 13, such as controlling the start and stop and the speed of the first water pump 12, and can also control the first control valve 13 to switch between the first state, the second state and the third state, etc., and the specific functions of the controller 3 are not specifically limited here. At the same time, the partition 42 of the mounting bracket 4 can separate the first integrated board 11 and the controller 3, thereby avoiding contact between the first integrated board 11 and the controller 3, and avoiding heat from the first integrated board 11 being transferred to the controller 3 to affect the normal operation of the controller 3. In addition, the first integrated board 11 and the controller 3 can make full use of the space on both sides of the partition 42 and have a reasonable layout to reduce the size of the partition 42 in a direction perpendicular to its thickness.
[0067] According to some embodiments of the utility model, the first water pump 12 and the first control valve 13 are arranged on one side of the first integrated board 11 in the thickness direction, and the first heat exchanger 14 is arranged on the other side of the first integrated board 11 in the thickness direction. Therefore, the first water pump 12, the first control valve 13, and the first heat exchanger 14 can make full use of the space on both sides of the first integrated board 11 in the thickness direction to prevent the layout of the first water pump 12, the first control valve 13, and the first heat exchanger 14 from being too crowded, which increases the difficulty of installation and disassembly. At the same time, it is conducive to reducing the overall size of the first integrated board 11 to reduce the installation space occupied by the thermal management module 100.
[0068] According to some embodiments of the utility model, the thermal management module 100 also includes: a second module 2, the second module 2 includes a second integrated board 21, a second water pump 22, a second control valve 24 and a second heat exchanger 25, and a flow channel 211 is formed in the second integrated board 21, so that the second water pump 22, the second control valve 24 and the second heat exchanger 25 arranged on the second integrated board 21 can be connected through the flow channel 211, that is, the second water pump 22, the second control valve 24 and the second heat exchanger 25 can be integrated on the second integrated board 21, thereby eliminating the cost of the pipeline for connecting the second water pump 22, the second control valve 24 and the second heat exchanger 25, and at the same time simplifying the structure of the second module 2 to reduce the layout difficulty and production cost of the thermal management module 100.
[0069] Among them, the second control valve 24 has a fourth state. In the fourth state, the second water pump 22, the second control valve 24, the second heat exchanger 25 and the flow channel 211 together constitute a fourth flow path, which is suitable for communicating with the heat exchange channel of the power battery and forming a closed fourth circulation flow path. The second heat exchanger 25 is used to connect the refrigerant circuit of the air conditioner and is located on the downstream side of the expansion valve 27. The second water pump 22 is used to drive the coolant flow in the fourth circulation flow path. It should be noted that the downstream side here is relative to the flow direction of the air conditioner refrigerant, that is, the refrigerant in the refrigerant circuit of the air conditioner enters the second heat exchanger 25 through the expansion valve 27.
[0070] That is to say, under the control of the second control valve 24, the heat exchange channel of the power battery can be connected to the second heat exchanger 25 through the fourth flow path. Therefore, under the drive of the second water pump 22, the coolant in the heat exchange channel of the power battery can enter the second heat exchanger 25 through the fourth flow path. At the same time, the refrigerant in the refrigerant circuit can enter the second heat exchanger 25 after expansion and cooling through the expansion valve 27, so that the refrigerant entering the second heat exchanger 25 can absorb the heat of the coolant of the power battery entering the second heat exchanger 25, and then the refrigerant returns to the refrigerant circuit, and the coolant of the power battery after cooling returns to the heat exchange channel of the power battery through the fourth flow path to cool the power battery, that is, the air conditioning refrigerant can be used to cool the power battery to ensure that the battery works within a suitable temperature range and improve the performance and safety of the battery. In addition, the flow rate of the refrigerant can be adjusted by adjusting the opening of the expansion valve 27 to control the cooling speed of the power battery by the refrigerant, avoid the temperature of the power battery from being out of control, and improve the reliability of the second module 2.
[0071] According to some embodiments of the utility model, the first module 1 further includes a third heat exchanger, which is connected in series with the second heat exchanger 25 to the refrigerant circuit of the air conditioner, and the third heat exchanger is located at the downstream side of the second heat exchanger 25 and is suitable for communicating with the heat exchange channel of the cabin heating component. Therefore, the refrigerant can enter the third heat exchanger after absorbing heat through heat exchange with the coolant of the second module 2 in the second heat exchanger 25, so as to release heat to the coolant in the first module 1, that is, the refrigerant can absorb the heat of the power battery to heat the coolant in the heat exchange channel of the cabin heating component of the first module 1, so that the heat of the refrigerant can be fully utilized to heat the passenger cabin, so as to improve the thermal management efficiency of the thermal management module.
[0072] According to some embodiments of the utility model, the second module 2 also includes a third water pump 23, and the second control valve 24 also has a fifth state and a sixth state. In the fifth state, the third water pump 23, the second control valve 24, the second heat exchanger 25 and the flow channel 211 together constitute a fifth flow path, and the fifth flow path is suitable for being connected to the heat exchange channel of the engine radiator and the electric drive system and forming a closed fifth circulation flow path; in the sixth state, the third water pump 23, the second control valve 24, the second heat exchanger 25 and the flow channel 211 together constitute a sixth flow path, and the sixth flow path is suitable for being connected to the heat exchange channel of the electric drive system and forming a closed sixth circulation flow path, and the third water pump 23 is used to drive the flow of coolant in the fifth circulation flow path and the sixth circulation flow path.
[0073] That is to say, when the second control valve 24 is switched to the fifth state, the heat exchange channel of the engine radiator can pass through the fifth flow path and the heat exchange channel of the electric drive system, that is, the fifth flow path can form a circulating channel connected with the heat exchange channel of the engine radiator and the heat exchange channel of the electric drive system, so that the coolant can circulate between the fifth flow path, the heat exchange channel of the engine radiator and the heat exchange channel of the electric drive system under the drive of the third water pump 23. It can be understood that the engine radiator is used to dissipate heat from the engine, and its heat exchange channel usually has a higher temperature, and the electric drive system such as the motor will also generate high temperature during operation.
[0074] Therefore, in the process of the coolant circulating in the fifth circulation flow path, when the coolant flows through the heat exchange channel of the engine radiator and the heat exchange channel of the electric drive system, it can absorb the heat of the engine radiator and the electric drive system, so that the engine radiator and the electric drive system are in a suitable temperature range, thereby improving the reliability of the engine radiator and the electric drive system. In addition, the second heat exchanger 25 is simultaneously connected to the refrigerant circuit of the air conditioner. When the coolant absorbs the heat of the engine radiator and the electric drive system, it can release heat to the refrigerant in the air conditioning refrigerant circuit to heat the refrigerant when flowing through the second heat exchanger 25. The heated refrigerant can release heat to the coolant in the first module 1 in the third heat exchanger, that is, the refrigerant can be used to absorb the heat of the engine radiator and the electric drive system to heat the coolant temperature in the first module 1, so that the first module 1 can be used to heat the passenger cabin and other locations. In other words, through the cooperation of the first module 1 and the second module 2, the heat from the engine radiator and the electric drive system can be used to heat the passenger cabin and other locations, thereby realizing the reuse of the heat from the engine radiator and the electric drive system, and the passenger cabin can be heated without activating the heaters of the engine and cabin heating components, thereby reducing the energy consumption of the heaters of the engine and cabin heating components.
[0075] It should be noted that when the engine is not started, the engine radiator can be used as a location for heat exchange between the coolant in the second module 2 and the external air, that is, when the external ambient temperature is high, the coolant in the second module 2 can be heated by air.
[0076] In addition, when the second control valve 24 is switched to the sixth state, the sixth flow path can form a circulation channel connected with the heat exchange channel of the electric drive system, so that the coolant can circulate between the sixth flow path and the heat exchange channel of the electric drive system. Therefore, in the process of the coolant circulating in the sixth circulation flow path, when the coolant flows through the heat exchange channel of the electric drive system, it can absorb the heat of the electric drive system, so that the electric drive system is within a suitable temperature range, thereby improving the reliability of the electric drive system. In addition, the second heat exchanger 25 is simultaneously connected to the refrigerant circuit of the air conditioner. When the coolant that absorbs the heat of the electric drive system flows through the second heat exchanger 25, it can release heat to the refrigerant in the refrigerant circuit of the air conditioner to heat the refrigerant. The heated refrigerant can release heat to the coolant in the first module 1 in the third heat exchanger, that is, the refrigerant can be used to absorb the heat of the engine radiator and the electric drive system to heat the coolant temperature in the first module 1, so that the first module 1 can be used to heat the passenger cabin and other locations. At the same time, the coolant in the sixth circulation flow path can be prevented from flowing through the engine radiator, thereby preventing the engine radiator temperature from being too low to cause the heat of the coolant to be lost, thereby improving the effect of heating the passenger cabin.
[0077] Therefore, during the use of the thermal management module 100, when the refrigerant temperature in the refrigerant circuit of the air conditioner needs to be heated, when the air temperature of the external environment is lower than the temperature of the electric drive system, the second control valve 24 is controlled to the sixth state, otherwise, the second control valve is controlled to the fifth state.
[0078] According to some embodiments of the present utility model, the second module 2 also includes a three-way valve 26, the three-way valve 26 includes a first control port 261, a second control port 262 and a third control port 263, the flow channel 211 includes a first flow channel 2111, a second flow channel 2112, a third flow channel 2113, a fourth flow channel 2114, a fifth flow channel 2115, a sixth flow channel 2116, a seventh flow channel 2117 and an eighth flow channel 2118, the second control valve 24 has a plurality of ports, the plurality of ports are respectively a first port 241, a second port 242, a third port 243, a fourth port 244, a fifth port 245 and a sixth port 246, the first flow channel 2111 is connected to the heat exchange channel of the power battery, the first heat exchanger 14 and the first port 241, the second flow channel 2112 is connected to the heat exchange channel of the power battery and the first control port 261, the second The water pump 22 is arranged in the second flow channel 2112, and the two ends of the third flow channel 2113 are respectively connected to the second port 242 and the second heat exchanger 25, the fourth flow channel 2114 is connected to the third port 243, the second control port 262 and the second heat exchanger 25, the fifth flow channel 2115 is connected to the first heat exchanger 14 and the third control port 263, the sixth flow channel 2116 is connected to the fourth port 244 and the heat exchange channel of the electric drive system, and a second water injection port 216 is also formed on the second integrated board 21, the seventh flow channel 2117 is connected to the fifth port 245, the heat exchange channel of the electric drive system, the heat exchange channel of the engine radiator and the second water injection port 216, the third water pump 23 is arranged in the seventh flow channel 2117, the eighth flow channel 2118 is connected to the sixth port 246 and the heat exchange channel of the engine radiator, and the second control valve 24 is used to control the connection or cutoff between multiple ports.
[0079] Therefore, the second control valve 24 can be used to control the connection relationship between the multiple ports, and the three-way valve 26 can be used to control the connection relationship between the first control port 261, the second control port 262 and the third control port 263, and the first flow channel 2111, the second flow channel 2112, the third flow channel 2113, the fourth flow channel 2114, the fifth flow channel 2115, the sixth flow channel 2116, the seventh flow channel 2117 and the eighth flow channel 2118 can be controlled to be connected or cut off to control the flow direction of the coolant in the second module 2. Among them, the second water injection port 216 can be connected to the second water tank, and the second water tank is used to store the coolant. Therefore, when the coolant is insufficient, the coolant in the first water tank can be added to the coolant in the seventh flow channel 2117 through the second water injection port 216, thereby avoiding the decrease in heat exchange efficiency due to insufficient coolant.
[0080] Specifically, in the fourth state, the second control valve 24 controls the first port 241 and the second port 242 to be connected, and the coolant flowing out of the heat exchange channel of the power battery enters the second module 2 and then enters the second heat exchanger 25 through the first flow channel 2111, the first port 241, the second port 242 and the third flow channel 2113 in sequence, and is discharged from the second heat exchanger 25 after heat exchange with the refrigerant in the refrigerant circuit of the air conditioner, and returns to the heat exchange channel of the power battery through the second control port 262, the first control port 261 and the second flow channel 2112 in sequence to cool the power battery. At this time, the second module 2 is in the fourth working mode, that is, the power battery is cooled by the refrigerant.
[0081] In the fifth state, the second control valve 24 controls the second port 242 and the sixth port 246, and the third port 243 and the fourth port 244 are connected. After the coolant flowing out of the heat exchange channel of the engine radiator enters the second module 2, it enters the heat exchange channel of the electric drive system through the seventh flow channel 2117. After the coolant flowing out of the heat exchange channel of the electric drive system enters the second module 2, it passes through the sixth flow channel 2116, the fourth port 244, the third port 243 and the fourth flow channel 2114 in sequence to enter the second heat exchanger 25, and after heat exchange with the refrigerant in the second heat exchanger 25, it is discharged from the second heat exchanger 25, and returns to the heat exchange channel of the engine radiator through the third flow channel 2113, the second port 242, the sixth port 246 and the eighth flow channel 2118 in sequence. At this time, the second module 2 is in the fifth working mode, that is, the refrigerant in the refrigerant circuit of the air conditioner is heated by using the heat of the engine radiator and the electric drive system.
[0082] In the sixth state, the second control valve 24 controls the second port 242 and the fifth port 245, and the third port 243 is connected to the fourth port 244. The coolant flowing out of the heat exchange channel of the electric drive system enters the second module 2 and then passes through the sixth flow channel 2116, the fourth port 244, the third flow channel 243 and the fourth flow channel 2114 to enter the second heat exchanger 25 in sequence, and is discharged from the second heat exchanger 25 after heat exchange with the refrigerant in the second heat exchanger 25, and returns to the heat exchange channel of the electric drive system in sequence through the third flow channel 2113, the second port 242, the fifth port 245 and the seventh flow channel 2117. At this time, the second module 2 is in the sixth working mode, that is, the refrigerant is heated by the heat of the electric drive system.
[0083] In addition, the coolant flowing out of the heat exchange channel of the power battery can enter the first heat exchanger 14 of the first module 1 through the first flow channel 2111 after entering the second module 2, and be discharged from the first heat exchanger 14 after exchanging heat with the coolant of the first module 1 in the first heat exchanger 14, and return to the second module 2 and then pass through the fifth flow channel 2115, the third control port 263, the first control port 261 and the second flow channel 2112 in sequence to return to the heat exchange channel of the power battery, so that the coolant of the power battery can pass through the first heat exchanger 14, exchange heat with the coolant of the first module 1, and then return to the heat exchange channel of the power battery.
