Description

Technical Field

[0001] This application relates to the field of thermal management technology for electric new energy vehicles, and in particular to a water-side integrated module, a thermal management integrated system, and a new energy vehicle. Background Technology

[0002] Thermal management integrated systems are used to manage the thermal performance of new energy vehicles, thereby ensuring that new energy vehicles maintain good performance, energy efficiency, and driving comfort under various operating conditions.

[0003] The thermal management integrated system includes a water-side integrated module and a refrigerant integrated module. The water-side integrated module includes flow channel components, several water valves, a liquid pump, and plate heat exchangers. The flow channel components can be flow plates or valve islands. The flow channel components are connected to the water-side loop of the plate heat exchanger in the refrigerant integrated module. The flow channel components have multiple flow channels for coolant flow. The water valves are connected to the flow channels of the flow channel components. After these flow channels are connected to other modules such as evaporators, condensers, or heat exchangers in the thermal management integrated system, multiple flow loops for coolant flow can be formed. This allows the coolant to exchange heat as it flows in different flow loops, thereby achieving the function of temperature regulation.

[0004] Currently, most refrigerant integrated modules use a primary refrigerant that offers higher safety but is also more expensive, resulting in higher manufacturing and operating costs for new energy vehicles. To reduce costs, a secondary refrigerant, which is cheaper and more efficient but carries flammable and explosive risks, can be selected. However, existing thermal management integrated systems are typically only compatible with the primary refrigerant and not the secondary refrigerant, making it difficult to implement the secondary refrigerant in new energy vehicles. Utility Model Content

[0005] This application provides a water-side integrated module, a thermal management integrated system, and a new energy vehicle. By setting up the water-side integrated module, the thermal management integrated system with the water-side integrated module can switch between a first refrigerant and a second refrigerant, and can realize the switching between the first refrigerant and the second refrigerant, so as to facilitate the testing and verification of the second refrigerant or its use in new energy vehicles.

[0006] In a first aspect, embodiments of this application provide a water-side integrated module, including:

[0007] The flow channel plate has a first inlet, a second inlet, and a first outlet, all of which are used to supply coolant flow.

[0008] A multi-port valve is mounted on a flow channel plate. The multi-port valve has a first port, a second port, a third port, and a fourth port. The first port and the second port are configured to be connected to the internal cooling flow channel of the battery. The third port and the fourth port are configured to be connected to the water exchange side loop of the inner plate of the refrigerant integration module. The first port, the battery, the second port, the fourth port, the refrigerant integration module, the third port, and the first port form a heat exchange loop. The coolant in the heat exchange loop is used to exchange heat with the refrigerant in the refrigerant integration module.

[0009] Both the first inlet and the second inlet are connected to the heat exchange circuit, and the first outlet can be connected to the heat exchange circuit. Both the first outlet and the second inlet can be selectively blocked or opened. The first outlet and the second inlet are configured to be blocked when the refrigerant is the first refrigerant. The first outlet and the second inlet are configured to be opened when the refrigerant is the second refrigerant. The first outlet is also configured to connect with the refrigeration module and the second inlet in the air conditioning blower module to form a heat exchange branch, and the heat exchange branch is connected to the heat exchange circuit. The first refrigerant includes tetrafluoroethane refrigerant or tetrafluoropropylene refrigerant, and the second refrigerant includes propane refrigerant.

[0010] The water-side integrated module provided in this application embodiment, through the setting of a first outlet and a second inlet, enables both the first refrigerant and the second refrigerant to be used for heat dissipation of components such as batteries. Therefore, when the water-side integrated module is set in the thermal management integrated system, since the water-side integrated module has a first outlet and a second inlet, the thermal management integrated system can switch between and be compatible with the first refrigerant and the second refrigerant, thereby improving the flexibility and adaptability of the thermal management system.

[0011] When the first refrigerant is used in the refrigerant integration module, the first outlet and the second inlet are blocked. The coolant circulates in the heat exchange circuit to absorb the heat from the battery and rise in temperature. After exchanging heat with the first refrigerant in the refrigerant integration module, it cools down, so as to indirectly dissipate heat from the battery through the first refrigerant.

[0012] When the refrigerant integration module uses the second refrigerant, the first outlet and the second inlet are open. Since the heat exchange branch and the heat exchange loop are interconnected, a portion of the coolant circulates in the heat exchange loop, absorbing heat from the battery and heating up. It then exchanges heat with the second refrigerant in the refrigerant integration module and cools down, facilitating heat dissipation from the battery through the second refrigerant. Simultaneously, another portion of the coolant flows through the first outlet and the second inlet through the heat exchange branch, exchanging heat with the refrigeration module in the air conditioning blower module and heating up to absorb heat from the air at the refrigeration module. The air conditioning blower module then blows the cooled air into the passenger compartment to achieve cooling of the passenger compartment.

[0013] Furthermore, the thermal management integrated system with a water-side integrated module is applied to new energy vehicles. Through the setting of the heat exchange branch, the coolant in the heat exchange branch is heated at the refrigeration module and can merge with the coolant in the heat exchange circuit. It then flows to the refrigerant integrated module to exchange heat with the second refrigerant and cool down. This eliminates the need for the second refrigerant to flow through the heat exchange branch. In this way, the second refrigerant can flow only in the refrigerant integrated module, making it less likely for the second refrigerant to be blown into the passenger compartment of the new energy vehicle by the air conditioning blower module in the event of a leak. This avoids the safety problems caused by the second refrigerant leak. Thus, when the thermal management integrated system uses the second refrigerant, it can ensure the safety of users when using new energy vehicles.

[0037] Secondly, embodiments of this application provide a thermal management integrated system, including:

[0038] Battery;

[0039] The refrigerant integration module has a refrigerant circuit. The refrigerant in the refrigerant circuit includes a first refrigerant or a second refrigerant. The first refrigerant includes tetrafluoroethane refrigerant or tetrafluoropropylene refrigerant. The second refrigerant includes propane refrigerant.

[0040] The air conditioning blower module includes a refrigeration module and a blower. The blower's air outlet faces the refrigeration module, and the blower is configured to blow air that has exchanged heat with the refrigeration module into the vehicle body. The refrigeration module includes a cooler or an evaporator.

[0041] As in any of the first aspects, the water-side integrated module has a first interface, a second interface, a third interface, a fourth interface, a first outlet, a first inlet, and a second inlet, and the first interface, the battery, the second interface, the fourth interface, the refrigerant integrated module, the third interface, and the first interface form a heat exchange loop;

The first refrigerant can flow to the evaporator and vaporize through the evaporator to absorb the heat of the air near the evaporator, thereby cooling the air around the evaporator. The cooled air is then blown into the passenger compartment by a blower for cooling.

[0076] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] This application provides an embodiment of a new energy vehicle. For example, a new energy vehicle may include electric vehicles and hybrid electric vehicles. A hybrid electric vehicle can refer to a new energy vehicle that combines an internal combustion engine and an electric motor as power systems.

[0078] New energy vehicles include integrated thermal management systems. These systems involve temperature control and energy efficiency optimization in multiple aspects to ensure the performance, efficiency, and comfort of new energy vehicles under various conditions.

[0079] In existing technologies, air conditioning systems use refrigerant to evaporate and absorb heat in the evaporator to lower the ambient air temperature. The air conditioning blower module then blows the heat-exchanged air into the passenger compartment of the new energy vehicle to cool or heat the passenger compartment.

[0080] Existing air conditioning blower modules include a blower, a refrigeration module, and a heating module. Specifically, the refrigeration module mainly includes a compressor, an expansion valve, a condenser, and an evaporator. When there is a cooling demand in the passenger compartment, the refrigerant in the refrigerant module is transferred to the evaporator, where it absorbs heat from the air and vaporizes, converting the air around the evaporator into low-temperature air. This air is then blown into the passenger compartment by the blower. After becoming a low-temperature, low-pressure gas, the refrigerant is drawn into the compressor and compressed into a high-temperature, high-pressure gas. It then enters the cooling circulation components in the refrigerant module to release heat, and then returns to the evaporator. This cycle continues, achieving the cooling of the passenger compartment.

[0081] Heating modules typically include heaters, which convert electrical energy into heat energy to directly heat the air flowing through them. The heated air is then blown into the passenger compartment by a blower, thus heating the passenger compartment.

[0082] The thermal management integrated system also includes a water-side integrated module. This module regulates the temperature of components such as the battery and motor through coolant circulation, ensuring that new energy vehicles maintain good performance, energy efficiency, and driving comfort under various operating conditions.

[0083] The water-side integrated module includes flow channel components and several water valves. The flow channel components can be flow channel plates or valve islands. The flow channel components are connected to the refrigerant module and have flow channels for coolant flow. The water valves are connected to the flow channels of the flow channel components.

[0084] In existing technologies, the flow channel is usually connected to the plate heat exchanger in the battery and refrigerant module to form a flow loop for the coolant to flow through. This allows the coolant to absorb the heat generated during battery operation as it flows through the flow loop. After absorbing the heat from the battery, the coolant exchanges heat with the refrigerant in the plate heat exchanger to cool down and then circulates back to the battery, thus achieving heat dissipation for the battery.

[0085] Currently, most refrigerant modules use R134a (tetrafluoroethane) or R1234yf (tetrafluoropropylene) refrigerants. Among them, R134a refrigerant has higher refrigeration performance and chemical stability, and can provide stable cooling effects over a wide temperature range. R1234yf refrigerant has a lower global warming potential (GWP) and less environmental impact, while also meeting the cooling requirements of water-side integrated modules.

[0086] However, the production costs of R134a and R1234yf refrigerants are relatively high, resulting in higher manufacturing and operating costs for new energy vehicles.

[0087] R290 (propane) refrigerant has a low GWP value, does not damage the ozone layer, and possesses good thermodynamic properties, resulting in high refrigeration efficiency and effective cooling and heating. However, R290 refrigerant poses a flammable and explosive risk; therefore, existing water-side integrated modules and thermal management integrated systems are not compatible with R290 refrigerant.

[0088] In view of this, this application provides a thermal management integrated system, including a battery, a refrigerant integrated module, an air conditioning blower module, and a water-side integrated module. The air conditioning blower module includes a refrigeration module and a blower, with the blower's outlet facing the refrigeration module, and the blower configured to blow air that has exchanged heat with the refrigeration module into the vehicle body; the refrigeration module includes a cooler or an evaporator. The refrigerant integrated module 600 has a refrigerant circuit, where the refrigerant includes a first refrigerant or a second refrigerant. The first refrigerant includes R134a and R1234yf refrigerants, etc., and the second refrigerant includes R290 refrigerant, etc.

[0089] The water-side integrated module has a first interface, a second interface, a third interface, a fourth interface, a first outlet, a first inlet, and a second inlet. The first interface, the battery, the second interface, the fourth interface, the refrigerant integrated module, the third interface, and the first interface form a heat exchange loop. Both the first and second inlets are connected to the heat exchange loop, and the first outlet can also be connected to the heat exchange loop. The first outlet and the second inlet are configured to be blocked when the refrigerant is the first refrigerant, and both ends of the evaporator are connected to the refrigerant loop. The first outlet and the second inlet are configured to be opened when the refrigerant is the second refrigerant, and the first outlet is also configured to connect to the cooler and the second inlet to form a heat exchange branch, and both ends of the heat exchange branch are connected to the heat exchange loop.

[0090] The thermal management integrated system provided in this application embodiment, through the setting of a first outlet and a second inlet, enables both the first refrigerant and the second refrigerant to be used for battery heat dissipation and passenger compartment cooling in new energy vehicles. Furthermore, when the water-side integrated module is set in the thermal management integrated system, since the water-side integrated module has a first outlet and a second inlet, the thermal management integrated system can switch between and be compatible with the first refrigerant and the second refrigerant, thereby improving the flexibility and adaptability of the thermal management system.

[0091] Furthermore, the thermal management integrated system with a water-side integrated module is applied to new energy vehicles. Through the setting of the heat exchange branch, the coolant in the heat exchange branch is heated at the refrigeration module and can merge with the coolant in the heat exchange circuit. It then flows to the refrigerant integrated module to exchange heat with the second refrigerant and cool down. This eliminates the need for the second refrigerant to flow through the heat exchange branch. In this way, the second refrigerant can flow only in the refrigerant integrated module, making it less likely for the second refrigerant to be blown into the passenger compartment of the new energy vehicle by the air conditioning blower module in the event of a leak. This avoids the safety problems caused by the second refrigerant leak. Thus, when the thermal management integrated system uses the second refrigerant, it can ensure the safety of users when using new energy vehicles.

[0092] The structure of the water-side integrated module of this application will be further described below with reference to the accompanying drawings.

Figure 1 , Figure 2 Schematic diagram of the structure of the water-side integrated module 100 provided in the embodiments of this application. Figure 2 , Figure 3 This is a schematic diagram of the structure of a thermal management integrated system 200 provided in an embodiment of this application. Figure 4 for Figure 3 A schematic diagram of the structure of the integrated heat management system 200 using the first refrigerant. Figure 5 for Figure 3 A schematic diagram of the structure of the integrated heat management system 200 using a second refrigerant.

[0094] See Figures 1 to 5 This embodiment provides a water-side integrated module 100, including a flow channel plate 1 and a multi-way valve 2. The flow channel plate 1 has a first inlet 14, a second inlet 15 and a first outlet 11, all of which are used to supply coolant flow.

[0095] The flow channel plate 1 has a structure containing multiple flow channels inside, which is used to guide the flow of coolant and realize the circulation of coolant in the water-side integrated module 100 and heat exchange with each module.

[0096] A multi-way valve 2 is disposed on the flow channel plate 1. The multi-way valve 2 has a first port 21, a second port 22, a third port 23 and a fourth port 24. The first port 21 and the second port 22 are configured to be connected to the internal cooling flow channel of the battery 300. The third port 23 and the fourth port 24 are configured to be connected to the refrigerant integration module 600. The first port 21, the battery 300, the second port 22, the fourth port 24, the refrigerant integration module 600, the third port 23 and the first port 21 form a heat exchange circuit 6. The coolant in the heat exchange circuit 6 is used to exchange heat with the refrigerant in the refrigerant integration module 600.

[0097] Specifically, the internal cooling channels of the battery 300 can remove the heat generated by the battery 300 during operation. The first inlet 14 and the second inlet 15 of the channel plate 1 are both connected to the heat exchange circuit 6, and the first outlet 11 can also be connected to the heat exchange circuit 6. Both the first outlet 11 and the second inlet 15 can be selectively blocked or opened. Furthermore, the first outlet 11 is configured to connect with the cooling module 510 and the second inlet 15 in the air conditioning blower module 500 to form a heat exchange branch 7, and the heat exchange branch 7 is connected to the heat exchange circuit 6.

[0098] Specifically, in this embodiment, the first refrigerant includes R134a refrigerant or R1234yf refrigerant, etc., and the second refrigerant includes R290 refrigerant, etc.

[0099] See Figure 3 and Figure 4 When the first refrigerant is used, the first outlet 11 and the second inlet 15 are blocked. The first interface 21 and the third interface 23 are interconnected, and the second interface 22 and the fourth interface 24 are interconnected. The coolant flows into the heat exchange circuit 6 through the first interface 21, carries away the heat generated by the battery 300 during operation through the internal cooling channel of the battery 300, and then heats up. It flows into the fourth interface 24 through the second interface 22, and then through the refrigerant integration module 600, where it exchanges heat with the first refrigerant and cools down. This transfers the heat generated by the battery 300 during operation to the first refrigerant. The coolant then flows through the first inlet 14 to the third interface 23, and then back to the first interface 21 to continue flowing into the battery 300, thus achieving heat dissipation of the battery 300.

[0100] In addition, in this embodiment, the refrigerant integration module 600 is also interconnected with the refrigeration module 510 in the air conditioning blower module 500. The first refrigerant can flow to the refrigeration module 510 to absorb the heat of the air around the refrigeration module 510 and then heat up. The air conditioning blower module 500 blows the cooled air to the passenger compartment and back into the refrigerant integration module 600, thereby achieving the cooling of the passenger compartment.

[0101] See Figure 3 and Figure 5When the second refrigerant is used, the first outlet 11 and the second inlet 15 are open. The first interface 21 and the third interface 23 are interconnected, the second interface 22 and the fourth interface 24 are interconnected, and the heat exchange circuit 6 and the heat exchange branch 7 are interconnected. A portion of the coolant flows into the heat exchange circuit 6 through the first interface 21, and after passing through the internal cooling channels of the battery 300, it carries away the heat generated during the operation of the battery 300 and becomes warmer. The first outlet 11 is interconnected with the heat exchange circuit 6, allowing another portion of the coolant to flow through the first outlet 11 to the heat exchange branch 7. The coolant then passes through the refrigeration module 510 and absorbs heat from the air surrounding the refrigeration module 510, becoming warmer. The air conditioning blower module 500 then blows the cooled air into the passenger compartment. The coolant flowing to the refrigeration module 510 exchanges heat with the refrigeration module 510 and then flows to the second inlet 15, where it merges with the coolant in the heat exchange circuit 6. After exchanging heat with the second refrigerant at the refrigerant integration module 600, it is cooled down and then returns to the third interface 23 and the first interface 21 through the first inlet 14 to achieve circulation. This achieves both heat dissipation of the battery 300 and cooling of the passenger compartment.

[0102] Meanwhile, the arrangement of the first outlet 11, the second inlet 15, and the heat exchange branch 7 allows the coolant to exchange heat with the refrigeration module 510 without the second refrigerant directly exchanging heat with the refrigeration module 510. This allows the second refrigerant to flow only in the refrigerant integration module 600, making it less likely for the second refrigerant to be blown into the passenger compartment by the air conditioning blower module 500 in the event of a leak. This avoids safety issues caused by the second refrigerant leak and ensures the safety of the water-side integration module 100.

[0103] In this embodiment, the location of the first outlet 11 is not restricted, and the location of the first outlet 11 can be selected adaptively according to actual needs.

[0104] For example, the first outlet 11 can be located between the first interface 21 and the inlet side of the internal cooling channel of the battery 300, or it can be located between the outlet side of the internal cooling channel of the battery 300 and the second interface 22.

[0105] See Figure 3 The water-side integrated module 100 provided in this embodiment also includes multiple liquid pumps 3. One of the liquid pumps 3 can be disposed between the first interface 21 and the inlet side of the internal cooling channel of the battery 300, and another liquid pump 3 can be disposed between the fourth interface 24 and the plate heat exchanger water-side inlet of the refrigerant integrated module 600. This enables adaptive adjustment of the flow rate and flow of the coolant, improving the flexibility and adaptability of the water-side integrated module 100.

[0106] See Figure 3In addition, the multi-way valve 2 provided in this embodiment also has a fifth port 25, a sixth port 26 and a seventh port 27. The flow channel plate 1 has a second outlet 12, a third outlet 13 and a third inlet 16. The fifth port 25, the sixth port 26 and the seventh port 27 are all connected to the motor module 400. The second outlet 12 is connected to the fifth port 25, the third outlet 13 is connected to the sixth port 26, and the third inlet 16 is connected to the seventh port 27. The coolant can flow from the fifth port 25 through the second outlet 12 to the motor module 400 and be heated to absorb the heat generated during the operation of the motor module 400. It can also flow from the sixth port 26 through the third outlet 13 to the motor module 400 and be heated to absorb the heat generated during the operation of the motor module 400. Then it merges at the outlet side of the motor module 400 and flows through the third inlet 16 to the seventh port 27.

[0107] The seventh interface 27 is connected to the fourth interface 24. The coolant flowing out of the fifth interface 25 can exchange heat with the refrigerant integration module 600 through the fourth interface 24 to cool down, and then pass through the third interface 23. At this time, part of the coolant flows through the first interface 21 to the internal cooling channel of the battery 300 to dissipate heat from the battery 300, and the other part of the coolant flows through the fifth interface 25 and the sixth interface 26 to the motor module 400 to dissipate heat from the motor module 400.

[0108] It should be noted that in this embodiment, one or both of the fifth interface 25 and the sixth interface 26 can be selectively turned on according to actual needs. When the fifth interface 25 and the sixth interface 26 are turned on at the same time, the flow rate of coolant is large and the heat dissipation efficiency of the motor module 400 is higher.

[0109] See Figure 3 In addition, the multi-way valve 2 also includes an eighth port 28 and a ninth port 29. The eighth port 28 is interconnected with the heating module 520 in the air conditioning blower module 500, and the ninth port 29 is interconnected with the refrigerant integration module 600. The refrigerant integration module 600 is also interconnected with the heating module 520 in the air conditioning blower module 500. When the refrigerant in the refrigerant integration module 600 absorbs heat from the coolant and heats up, the coolant flowing out from the ninth port 29 can flow to the refrigerant integration module 600 and absorb the heat from the refrigerant to cool and heat up the refrigerant. Then, it flows to the heating module 520 to transfer the heat absorbed by the coolant to the air around the heating module 520, thereby heating the air and cooling the coolant. The heated air is then blown into the passenger compartment by the air conditioning blower module for heating, thus improving energy utilization and avoiding energy waste.

[0110] Meanwhile, after the heating module 520 absorbs the heat from the coolant, the cooled coolant returns to the multi-way valve 2 through the eighth port 28. Depending on the current opening state of the multi-way valve 2, it can flow to the first port 21 or the fifth port 25 to dissipate heat from the motor module 400 or the battery 300.

[0111] See Figure 3 In addition, the water-side integrated module 100 provided in this embodiment also includes a first water tank 4 and a second water tank 5. The first water tank 4 is interconnected with the ninth interface 29, and the second water tank 5 is interconnected with the heat dissipation circuit to supplement and regulate the coolant for the water-side circuit of the thermal management integrated system 200.

[0112] The water-side integrated module 100 also includes a liquid pump 3, which is located between the ninth interface 29 and the plate heat exchanger water-side inlet of the refrigerant integrated module 600, thereby enabling adaptive adjustment of the flow rate and volume of the coolant, improving the flexibility and adaptability of the water-side integrated module 100.

[0113] It should be noted that, in this embodiment, the refrigerant integration module 600 has two plate-side water exchange inlets and two plate-side water exchange outlets. One plate-side water exchange inlet is used to exchange heat with the coolant in the heat dissipation circuit to cool the coolant and heat the refrigerant. The other plate-side water exchange inlet is used to exchange heat with the coolant flowing out of the ninth interface 29 to heat the coolant and cool the refrigerant. One plate-side water exchange outlet is connected to the refrigeration module 510 so that the low-temperature refrigerant heats up after exchanging heat with the refrigeration module 510. The other plate-side water exchange outlet is connected to the heating module 520 so that the heated refrigerant heats up after exchanging heat with the heating module 520.

[0114] Meanwhile, the refrigerant integration module 600 has a refrigerant circuit 610 for the flow of refrigerant and heat exchange with coolant.

[0115] The water-side integrated module 100 provided in this embodiment achieves the switching between the first refrigerant and the second refrigerant by opening or blocking the first outlet 11 and the second inlet 15, so that both the first refrigerant and the second refrigerant can be used for heat dissipation of the battery 300. Thus, when the refrigerant integrated module 600 and the water-side integrated module 100 are set in the thermal management integrated system 200, the thermal management integrated system 200 can switch between and be compatible with the first refrigerant and the second refrigerant, thereby improving the flexibility and adaptability of the thermal management integrated system 200.

[0116] Meanwhile, when using the second refrigerant, the heat exchange branch 7 enables the coolant to exchange heat with the refrigeration module 510 in the air conditioning blower module 500 to increase its temperature, thereby absorbing the heat from the air in the refrigeration module 510. The cooled air is then blown into the passenger compartment by the air conditioning blower module 500 to achieve the cooling of the passenger compartment.

[0117] Furthermore, the thermal management integrated system 200, equipped with a water-side integrated module 100, is applied to new energy vehicles. When the passenger compartment needs to be cooled, the coolant in the heat exchange branch 7 is heated at the cooling module 510 and can then merge with the coolant in the heat exchange circuit 6. It flows to the plate heat exchanger in the refrigerant integrated module 600 to exchange heat with the second refrigerant and then cool down. This eliminates the need for the second refrigerant to flow through the heat exchange branch 7. In this way, the second refrigerant can flow only in the refrigerant integrated module 600, making it less likely for the second refrigerant to be blown into the passenger compartment of the new energy vehicle by the air conditioning blower module 500 when it leaks. This avoids the safety problems caused by the leakage of the second refrigerant. Thus, when the thermal management integrated system 200 uses the second refrigerant, it can ensure the safety of users when using new energy vehicles.

[0118] See Figure 1 and Figure 2 In some embodiments, the flow channel plate 1 includes a first flow channel plate 1a or a second flow channel plate 1b. In the first flow channel plate 1a, the first outlet 11 and the second inlet 15 are both sealed openings. In the second flow channel plate 1b, the first outlet 11 and the second inlet 15 are both open openings communicating with the outside.

[0119] In this embodiment, the flow channel plate is mass-produced using a pre-designed mold. The first outlet 11 and the second inlet 15 in the first flow channel plate 1a can be designed as a closed structure directly during production, or they can be sealed using a sealing plug or other structures. This embodiment does not impose any restrictions on this.

[0120] Correspondingly, the first outlet 11 and the second inlet 15 in the second flow channel plate 1b can be designed as an open structure by directly designing the mold during production.

[0121] See Figure 3 and Figure 4 Specifically, when the first refrigerant is required, the first flow channel plate 1a can be used. At this time, the first outlet 11 and the second inlet 15 are blocked. The coolant only circulates in the heat exchange circuit 6, and heats up after exchanging heat with the battery 300, and cools down after exchanging heat with the first refrigerant, thus meeting the heat dissipation requirements of the battery 300.

[0122] See Figure 3 and Figure 5 When a second refrigerant is required, the second flow channel plate 1b can be used. At this time, the first outlet 11 and the second inlet 15 are in the open state. The coolant not only circulates in the heat exchange circuit 6, but also flows through the first outlet 11 through the heat exchange branch 7. It is heated by the refrigeration module 510 to absorb the heat of the air around the refrigeration module 510, and then the cooled air is blown to the passenger compartment by the air conditioning blower module 500 to achieve the cooling of the passenger compartment.

[0123] Meanwhile, the installation of the second flow channel plate 1b facilitates the testing, verification, and practical application of the second refrigerant, avoiding the risks associated with refrigerant leakage.

[0124] By setting up the first flow channel plate 1a and the second flow channel plate 1b, the water-side integrated module 100 can flexibly adjust the flow path of the coolant according to different refrigerant types and usage requirements, thereby achieving more efficient thermal management and higher adaptability.

[0125] See Figure 1 and Figure 2 In some embodiments, the water-side integrated module 100 further includes a sealing element (not shown in the figure), and the flow channel plate 1 is provided with a sealing element in the first outlet 11 and the second inlet 15 respectively, and the sealing element is detachably connected to the flow channel plate 1.

[0126] Specifically, in this embodiment, the flow channel plate 1 uses a sealing component to open and close the first outlet 11 and the second inlet 15.

[0127] The sealing component can be a rubber plug, which can be interference-fitted with the first outlet 11 and the second inlet 15 to achieve a tight seal through the elastic deformation of the rubber plug, effectively preventing coolant leakage from the first outlet 11 and the second inlet 15.

[0128] In another embodiment, the plugging component can also be a plugging cap, which has a sealing element inside. The plugging component is screwed onto the first outlet 11 and the second inlet 15, and the sealing element is pressed between the plugging cap and the first outlet 11, or between the plugging cap and the second inlet 15, to ensure the sealing of the coolant and prevent coolant leakage.

[0129] In other embodiments, the structure of the sealing element can be adapted, and this embodiment does not impose any restrictions on this.

[0130] See Figures 3 to 5 In some embodiments, the first outlet 11 forms the inlet end of the heat exchange branch 7. The first outlet 11 is configured to be located between the first interface 21 and the inlet side of the internal cooling channel of the battery 300. The first outlet 11 is connected to the first interface 21 and can be connected to the inlet side of the internal cooling channel of the battery 300. The second inlet 15 forms the outlet end of the heat exchange branch 7. The second inlet 15 is configured to be located between the fourth interface 24 and the plate water exchange side inlet of the refrigerant integration module 600. The second inlet 15 is connected to both the fourth interface 24 and the plate water exchange side inlet of the refrigerant integration module 600. This allows the coolant to be split between the heat exchange branch 7 and the heat exchange loop 6, ensuring the heat dissipation efficiency of the battery 300 and the cooling module 510.

[0131] See Figure 3 and Figure 5 Specifically, when using the second refrigerant, the first outlet 11 and the second inlet 15 are open, the first interface 21 and the third interface 23 are interconnected, and the second interface 22 and the fourth interface 24 are interconnected. Coolant flows into the heat exchange circuit 6 through the first interface 21. A portion of the coolant flows to the inlet side of the internal cooling channel of the battery 300, carrying away the heat generated during the operation of the battery 300 and then heating up. It then flows into the fourth interface 24 through the second interface 22. The other portion of the coolant flows into the heat exchange branch 7 through the first outlet 11, where it is heated by the refrigeration module 510 to absorb heat from the air surrounding the refrigeration module 510. The cooled air is then blown into the passenger compartment by the air conditioning blower module 500, thus achieving the cooling of the passenger compartment. The coolant that has heated up after flowing into the cooling module 510 flows into the second inlet 15 and merges with the coolant that carries away the heat from the battery 300 flowing into the fourth interface 24. Then it flows into the plate water exchange side channel in the refrigerant integration module 600. At the refrigerant integration module 600, it exchanges heat with the second refrigerant and cools down. Then it returns to the third interface 23 and the first interface 21 through the first inlet 14 to achieve circulation. Thus, while cooling the battery 300, it also cools the crew cabin.

[0132] See Figures 3 to 5 In some embodiments, the water-side integrated module 100 further includes a first three-way valve 8 having a first inlet 81, a first outlet 82, and a second outlet 83, wherein the first inlet 81 is configured to communicate with at least one of the first outlet 82 and the second outlet 83.

[0133] The first inlet end 81 is configured to communicate with the first interface 21, the first outlet end 82 is configured to communicate with the inlet side of the internal cooling channel of the battery 300, and the second outlet end 83 is configured to be located between the second interface 22 and the outlet side of the internal cooling channel of the battery 300, and the second outlet end 83 is connected to both the second interface 22 and the outlet side of the internal cooling channel of the battery 300. The first outlet 11 is located between the first interface 21 and the first inlet end 81, and the first outlet 11 is connected to the first interface 21.

[0134] Specifically, this embodiment achieves the diversion of coolant in the heat exchange circuit 6 and the heat exchange branch 7 by setting the first three-way valve 8, and can adapt to a variety of different heat dissipation requirements, thereby improving the flexibility and adaptability of the water-side integrated module 100.

[0135] When the heat dissipation requirement of the battery 300 is high, the first outlet end 82 of the first three-way valve 8 can be opened and the second outlet end 83 of the first three-way valve 8 can be closed to ensure the flow rate of coolant to the battery 300. After the coolant in the first interface 21 flows from the first inlet end 81 of the first three-way valve 8 to the first outlet end 82, it flows to the inlet side of the internal cooling channel of the battery 300 to absorb the heat generated during the operation of the battery 300 and rise in temperature. Then, it flows from the outlet side of the internal cooling channel of the battery 300 into the first inlet 14 and then into the second interface 22. After passing through the fourth interface 24, it exchanges heat with the refrigerant integration module 600 and cools down to ensure the heat dissipation effect of the battery 300.

[0136] When the heat dissipation requirement of the battery 300 is low, the first outlet end 82 and the second outlet end 83 of the first three-way valve 8 can be opened. The second outlet end 83 is connected to the second interface 22 and the outlet side of the internal cooling channel of the battery 300, respectively. This allows the coolant in the first interface 21 to be diverted to the first outlet end 82 and the second outlet end 83 through the first inlet end 81 of the first three-way valve 8. The coolant flowing out of the first outlet end 82 can absorb heat from the battery 300 and rise in temperature, while the coolant flowing out of the second outlet end 83 can directly merge with the coolant flowing out of the first outlet end 82 without passing through the heat exchange circuit 6. This avoids excessive heat exchange between the coolant and the battery 300, resulting in a lower temperature for the battery 300 and thus improving the thermal management performance of the entire water-side integrated module 100. At the same time, after the coolant flowing out of the second outlet end 83 merges with the coolant flowing out of the first outlet end 82, it passes through the fourth interface 24 and exchanges heat with the refrigerant integrated module 600 to cool the coolant.

[0137] See Figure 3 and Figure 5 When the second refrigerant is used and the battery 300 has no heat dissipation requirement, but the passenger compartment has a cooling requirement, the first outlet end 82 of the first three-way valve 8 can be closed. At this time, the coolant flowing out from the first interface 21 flows directly into the heat exchange branch 7 through the first outlet 11. The coolant is heated by the cooling module 510 in the heat exchange branch 7 to absorb the heat of the air around the cooling module 510. Then, the cooled air is blown into the passenger compartment by the air conditioning blower module 500 to achieve the cooling of the passenger compartment. Then, it returns to the first interface 21 through the third interface 23 for circulation.

[0138] See Figure 1 and Figure 2 In some embodiments, the first three-way valve 8 includes a proportional three-way valve.

[0139] Specifically, the proportional three-way valve can precisely adjust the distribution ratio of coolant in different flow channels according to the control signal, thereby achieving precise control of coolant flow. This allows for flexible adjustment of coolant flow distribution in heat exchange circuit 6 and heat exchange branch 7 according to different operating conditions and requirements, optimizing the thermal management performance of the water-side integrated module 100 and improving operational stability.

[0140] For example, when the heat dissipation demand of the battery 300 is high, the opening and closing degree of the first inlet end 81 and the first outlet end 82 can be appropriately increased, while the second outlet end 83 can be decreased or closed to increase the flow rate of the coolant flowing through the heat exchange circuit 6 and improve the heat dissipation efficiency of the battery 300. When the heat dissipation demand of the battery 300 is low, the opening and closing degree of the first outlet end 82 can be appropriately decreased to reduce the flow rate of the coolant flowing through the heat exchange circuit 6.

[0141] See Figures 3 to 5 In some embodiments, the flow channel plate 1 has a first branch flow channel 61, a second branch flow channel 62 and a third branch flow channel 63, and the inlet ends of the first branch flow channel 61 and the second branch flow channel 62 are connected to the outlet side of the internal cooling flow channel of the battery 300.

[0142] The outlet end of the first branch channel 61 is located between the first outlet end 82 and the outlet side of the internal cooling channel of the battery 300. The outlet end of the first branch channel 61 is connected to both the first outlet end 82 and the inlet side of the internal cooling channel of the battery 300. This allows the coolant flowing out from the outlet side of the internal cooling channel of the battery 300 to absorb heat from the battery 300 and then merge with the coolant flowing out from the first outlet end 82 through the first branch channel 61, flowing back to the inlet side of the internal cooling channel of the battery 300 to absorb heat generated during the operation of the battery 300 again, thereby enabling more precise control of the operating temperature of the battery 300.

[0143] The outlet end of the second branch channel 62 is connected to the second interface 22, the inlet end of the third branch channel 63 is connected to the second outlet end 83, and the outlet end of the third branch channel 63 is connected to the second branch channel 62. This can better regulate the operating temperature of the battery 300 and ensure the heat dissipation effect of the battery 300.

[0144] See Figures 3 to 5 In some embodiments, the first outlet 11 forms the inlet end of the heat exchange branch 7. The first outlet 11 is configured to be located between the third interface 23 and the refrigerant integration module 600, and the first outlet 11 is connected to the third interface 23. The first outlet 11 is also configured to be connected to the heat exchange loop 6.

[0145] The second inlet 15 forms the outlet end of the heat exchange branch 7. The second inlet 15 is constructed to be located between the fourth interface 24 and the plate water exchange side inlet of the refrigerant integration module 600, and the second inlet 15 is connected to the fourth interface 24 and the plate water exchange side inlet of the refrigerant integration module 600 respectively.

[0146] Specifically, in this embodiment, the first outlet 11 is connected to the third interface 23 and forms the inlet end of the heat exchange branch 7. The second inlet 15 is connected to the fourth interface 24 and the plate water exchange side inlet of the refrigerant integration module 600, and forms the outlet end of the heat exchange branch 7.

[0147] See Figure 3 and Figure 5 When the second refrigerant is used, the first outlet 11 and the second inlet 15 are open, the first interface 21 and the third interface 23 are interconnected, and the second interface 22 and the fourth interface 24 are interconnected. The coolant flows into the heat exchange circuit 6 through the first interface 21, carries away the heat generated by the battery 300 during operation after passing through the internal cooling channel of the battery 300, and then rises in temperature. It then flows through the second interface 22 to the fourth interface 24 to exchange heat with the refrigerant integration module 600 and cool down. At this time, part of the coolant enters the heat exchange circuit 6 through the third interface 23 and the first interface 21 for circulation and flows back to the fourth interface 24. Another part of the coolant enters the heat exchange branch 7 through the first outlet 11, so that the coolant passes through the refrigeration module 510 and absorbs the heat of the air around the refrigeration module 510 and is heated. The air conditioning blower module 500 blows the cooled air to the passenger compartment, and then merges with the coolant at the fourth interface 24 through the second inlet 15 and enters the refrigerant integration module 600 for heat exchange and cooling. Thus, while cooling the battery 300, it can also cool the passenger compartment.

[0148] Furthermore, through the arrangement of the first outlet 11, the second inlet 15, and the heat exchange branch 7, the coolant in the heat exchange branch 7, after being heated at the refrigeration module 510, can merge with the coolant in the heat exchange circuit 6 and flow to the refrigerant integration module 600 to exchange heat with the second refrigerant and then cool down. This allows the second refrigerant to flow only through the refrigerant integration module 600, making it less likely for the second refrigerant to be blown into the passenger compartment by the air conditioning blower module 500 in the event of a leak. This avoids the safety problems caused by the leakage of the second refrigerant and thus ensures the safety of the water-side integration module 100.

[0149] Figure 6 This is a schematic diagram of another thermal management integrated system 200 provided in an embodiment of this application. Figure 7 for Figure 6 A schematic diagram of the structure of the integrated heat management system 200 using the first refrigerant. Figure 8 for Figure 6A schematic diagram of the structure of the integrated heat management system 200 using a second refrigerant.

[0150] See Figures 6 to 8 In some embodiments, the water-side integrated module 100 further includes a second three-way valve 9 having a second inlet 91, a third outlet 92 and a fourth outlet 93, wherein the second inlet 91 is configured to communicate with at least one of the third outlet 92 and the fourth outlet 93.

[0151] The second three-way valve 9 is located between the third interface 23 and the refrigerant integration module 600. The second inlet end 91 is configured to connect with the plate heat exchanger side outlet of the refrigerant integration module 600. The fourth outlet end 93 is configured to connect with the third interface 23. The third outlet end 92 is connected with the first outlet 11.

[0152] Specifically, this embodiment achieves the diversion of coolant in the heat exchange circuit 6 and the heat exchange branch 7 by setting the second three-way valve 9, and can adapt to a variety of different heat dissipation requirements, thereby improving the flexibility and adaptability of the water-side integrated module 100.

[0153] See Figure 6 and Figure 7 When using the first refrigerant, the second inlet 91 and the fourth outlet 93 of the second three-way valve 9 can be opened, and the third outlet 92 can be closed, thereby shutting off the heat exchange branch 7. At this time, the coolant only flows in the heat exchange circuit 6 to dissipate heat from the battery 300.

[0154] The flow path of the coolant has been described in the above embodiments and will not be repeated here.

[0155] See Figure 6 and Figure 8When using the second refrigerant, the second inlet 91, third outlet 92, and fourth outlet 93 of the second three-way valve 9 can be opened. The coolant flows into the heat exchange circuit 6 through the first interface 21, and after passing through the internal cooling channel of the battery 300, it carries away the heat generated by the battery 300 during operation and becomes heated. Then, it flows through the second interface 22 to the fourth interface 24 to exchange heat with the refrigerant integration module 600 and become cooled. At this time, part of the coolant flows sequentially through the second inlet 91, the fourth outlet 93, the third interface 23, and the first interface 21 into the heat exchange circuit 6 for circulation and then flows back to the fourth interface 24. Another part of the coolant flows sequentially through the second inlet 91, the third outlet 92, and the first outlet 11 into the heat exchange branch 7, so that the coolant passes through the refrigeration module 510 and absorbs the heat of the air around the refrigeration module 510 and is heated. The air conditioning blower module 500 blows the cooled air to the passenger compartment, and then the coolant flows through the second inlet 15 and the fourth interface 24 to merge and enter the refrigerant integration module 600 for heat exchange. Thus, while cooling the battery 300, it can also cool the passenger compartment.

[0156] See Figure 1 and Figure 2 In some embodiments, the second three-way valve 9 includes a proportional three-way valve.

[0157] Specifically, the proportional three-way valve can precisely adjust the distribution ratio of coolant in different flow channels according to the control signal, thereby achieving precise control of coolant flow. This allows for flexible adjustment of coolant flow distribution in heat exchange circuit 6 and heat exchange branch 7 according to different operating conditions and requirements, optimizing the thermal management performance of the water-side integrated module 100 and improving operational stability.

[0158] For example, when the heat dissipation requirement of battery 300 is low, the opening degree of the fourth outlet 93 can be appropriately reduced, thereby reducing the flow rate of coolant to heat exchange circuit 6. When the cooling requirement of the crew compartment is high, the opening degree of the third outlet 92 can be increased to increase the flow rate of coolant to heat exchange branch 7.

[0159] See Figures 6 to 8 In an embodiment where the water-side integrated module 100 includes a second three-way valve 9, the water-side integrated module 100 may further include a first three-way valve 8, the first three-way valve 8 having a first inlet end 81, a first outlet end 82 and a second outlet end 83, the first inlet end 81 being configured to communicate with at least one of the first outlet end 82 and the second outlet end 83.

[0160] The first inlet end 81 is configured to be connected to the first interface 21, the first outlet end 82 is configured to be connected to the inlet side of the internal cooling channel of the battery 300, and the second outlet end 83 is configured to be located between the second interface 22 and the outlet side of the internal cooling channel of the battery 300, and the second outlet end 83 is connected to the second interface 22 and the outlet side of the internal cooling channel of the battery 300 respectively.

[0161] Specifically, this embodiment achieves the diversion of coolant in the heat exchange circuit 6 by setting the first three-way valve 8, thereby improving the temperature control accuracy of the battery 300.

[0162] The flow path of the coolant in the heat exchange branch 7 has been described in the above embodiments and will not be repeated here.

[0163] When it is necessary to dissipate heat from the battery 300, the first outlet end 82 of the first three-way valve 8 can be opened and the second outlet end 83 of the first three-way valve 8 can be closed. The coolant in the first interface 21 flows from the first inlet end 81 of the first three-way valve 8 to the first outlet end 82, and then flows to the inlet side of the internal cooling channel of the battery 300 to absorb the heat generated during the operation of the battery 300 and rise in temperature. Then it flows from the outlet side of the internal cooling channel of the battery 300 into the first inlet 14 and then into the second interface 22. After passing through the fourth interface 24, it exchanges heat with the refrigerant integration module 600 to achieve the cooling of the coolant.

[0164] When the heat dissipation requirement of the battery 300 is high, the first outlet end 82 of the first three-way valve 8 can be opened and the second outlet end 83 can be closed to ensure the flow of coolant to the battery 300. The second outlet end 83 is connected to the second interface 22 and the outlet side of the internal cooling channel of the battery 300, respectively. This allows the coolant in the first interface 21 to flow to the first outlet end 82 through the first inlet end 81 of the first three-way valve 8. The coolant flowing out of the first outlet end 82 can absorb the heat of the battery 300 and rise in temperature. Then, it passes through the fourth interface 24 and exchanges heat with the refrigerant integration module 600 to cool the coolant and ensure the heat dissipation efficiency of the battery 300.

[0165] See Figure 6 and Figure 8When the second refrigerant is used and the battery 300 has no heat dissipation requirement, but the passenger compartment has a cooling requirement, the fourth outlet 93 of the second three-way valve 9 is closed. At this time, the coolant flows directly out from the fourth port 24, passes through the refrigerant integration module 600, and then flows into the heat exchange branch 7 through the third outlet 92 of the second three-way valve 9. In the heat exchange branch 7, the coolant absorbs heat from the air around the refrigeration module 510 and rises in temperature. The air conditioning blower module 500 blows the cooled air into the passenger compartment. The heated coolant then exchanges heat with the second refrigerant through the refrigerant integration module 600 to achieve cooling of the coolant. Finally, it circulates through the second inlet 91 and the third outlet 92 of the second three-way valve 9, thereby achieving cooling of the passenger compartment.

[0166] See Figures 6 to 8 In some embodiments, the first three-way valve 8 includes a proportional three-way valve.

[0167] Specifically, when the first three-way valve 8 is a proportional three-way valve, it has been described in the above embodiments and will not be repeated here.

[0168] See Figures 6 to 8 In some embodiments, the flow channel plate 1 has a first branch flow channel 61, a second branch flow channel 62, and a third branch flow channel 63. The inlet ends of the first branch flow channel 61 and the second branch flow channel 62 are connected to the outlet side of the internal cooling flow channel of the battery 300. The outlet end of the first branch flow channel 61 is located between the first outlet end 82 and the outlet side of the internal cooling flow channel of the battery 300, and the outlet end of the first branch flow channel 61 is connected to the first outlet end 82 and the outlet side of the internal cooling flow channel of the battery 300, respectively.

[0169] The outlet end of the second branch channel 62 is connected to the second interface 22; the inlet end of the third branch channel 63 is connected to the second outlet end 83, and the outlet end of the third branch channel 63 is connected to the second branch channel 62.

[0170] The first branch flow channel 61 and the third branch flow channel 63 form a branch flow in the heat exchange loop 6, and the flow cross-sectional area of ​​at least one of the first branch flow channel 61 and the third branch flow channel 63 is smaller than the flow cross-sectional area of ​​other flow channels in the heat exchange loop 6.

[0171] It should be noted that the flow cross-sectional area is the area of ​​the surface within the flow channel that is perpendicular to the flow direction of the flow channel.

[0172] Specifically, in embodiments where the water-side integrated module 100 includes a first three-way valve 8 but does not include a second three-way valve 9, by setting at least one or both of the first branch flow channel 61 and the third branch flow channel 63 to have a flow cross-sectional area smaller than that of other flow channels in the heat exchange circuit 6, the second three-way valve 9 can be replaced. This allows adjustment of the flow rate of coolant entering the heat exchange circuit 6 and the flow rate of coolant entering the cooler in the 510 through the heat exchange circuit 6. After the coolant enters the heat exchange circuit 6 to dissipate heat from the battery 300, a small portion of the coolant can directly pass through the first branch flow channel 61 and mix with the coolant flowing out of the first outlet 82 before re-entering the heat exchange circuit 6. This causes the coolant to heat up, preventing the coolant flowing into the heat exchange circuit 6 from being too cold. At the same time, it can also adjust the flow rate of coolant entering the cooler in the 510 through the heat exchange circuit 6 to regulate the cooling capacity in the cockpit.

[0173] Therefore, in the embodiment where the water-side integrated module 100 is equipped with only the first three-way valve 8 and does not include the second three-way valve 9, the flow rate of the coolant can be further adjusted through the first branch flow channel 61 and the third branch flow channel 63 on the basis of the first three-way valve 8, thereby achieving precise control of the coolant flow rate and further improving the thermal management performance of the entire water-side integrated module 100.

[0174] It should be noted that in embodiments where the water-side integrated module 100 includes both the first three-way valve 8 and the second three-way valve 9, the flow cross-sectional area of ​​at least one or both of the first branch flow channel 61 and the third branch flow channel 63 can be set to be smaller than the flow cross-sectional area of ​​other flow channels in the heat exchange circuit 6. In this way, based on the first three-way valve 8 and the second three-way valve 9, the first branch flow channel 61 and the third branch flow channel 63 can achieve more precise control of the coolant flow rate, and further improve the thermal management performance of the entire water-side integrated module 100.

[0175] See Figures 3 to 5 Secondly, this embodiment provides a thermal management integrated system 200, which includes a battery 300, a refrigerant integrated module 600, an air conditioning blower module 500, and a water-side integrated module 100 as described in any embodiment of the first aspect.

[0176] The refrigerant integration module 600 includes a refrigerant circuit 610. The refrigerant in the refrigerant circuit 610 includes a first refrigerant or a second refrigerant. The first refrigerant includes R134a refrigerant and R1234yf refrigerant, and the second refrigerant includes R290 refrigerant.

[0177] The air conditioning blower module 500 includes a refrigeration module 510 and a blower 530. The air outlet of the blower 530 faces the refrigeration module 510, and the blower 530 is configured to blow air that has exchanged heat with the refrigeration module 510 into the vehicle body. The refrigeration module 510 includes a cooler or an evaporator.

[0178] A water-side integrated module 100 has a first interface 21, a second interface 22, a third interface 23, a fourth interface 24, a first outlet 11, a first inlet 14, and a second inlet 15. The first interface 21, battery 300, second interface 22, fourth interface 24, refrigerant integrated module 600, third interface 23, and first interface 21 form a heat exchange loop 6. Both the first inlet 14 and second inlet 15 are connected to the heat exchange loop 6. The first outlet 11 can also be connected to the heat exchange loop 6. The first outlet 11 and second inlet 15 are configured to be blocked when the refrigerant is the first refrigerant. Both ends of the evaporator are connected to the refrigerant loop 610. The first outlet 11 and second inlet 15 are configured to be opened when the refrigerant is the second refrigerant. The first outlet 11 is also configured to connect to the cooler and second inlet 15 to form a heat exchange branch 7, and both ends of the heat exchange branch 7 are connected to the heat exchange loop 6.

[0179] In this embodiment, the refrigerant circuit 610 includes a cooling circulation component to cool down and circulate the refrigerant that has heated up after absorbing heat in the refrigerant circuit.

[0180] The cooling cycle components can include a compressor, condenser, expansion valve, and evaporator. The refrigerant circuit 610 also includes a compressor, which compresses the refrigerant, which absorbs heat from the coolant and heats up, into a high-temperature, high-pressure gas. The condenser cools the high-temperature, high-pressure refrigerant gas, causing it to release heat and become a high-pressure liquid. The liquid then passes through the expansion valve for throttling and pressure reduction, becoming a low-temperature, low-pressure liquid that absorbs heat from the coolant again, thus completing the cycle.

[0181] Specifically, when using the first refrigerant, the first outlet 11 and the second inlet 15 are blocked. The coolant circulates in the heat exchange circuit 6 to absorb the heat from the battery and rise in temperature. After exchanging heat with the first refrigerant in the refrigerant integration module 600, it cools down, so as to indirectly dissipate heat from the battery 300 through the first refrigerant.

[0182] Meanwhile, the two ends of the evaporator are connected to the refrigerant circuit 610, and the first refrigerant can flow to the evaporator. The first refrigerant is vaporized by the evaporator to absorb the heat of the air near the evaporator, thereby cooling the air around the evaporator. The cooled air is then blown into the passenger compartment by the blower 530 for cooling.

[0183] When using the second refrigerant, the first outlet and the second inlet are opened. The coolant circulates in the heat exchange circuit, absorbing heat from the battery and heating up. It then exchanges heat with the second refrigerant in the refrigerant integration module and cools down, so as to dissipate heat from the battery through the second refrigerant.

[0184] Meanwhile, the coolant can also flow through the first outlet 11 and the second inlet 15 through the heat exchange branch 7, and exchange heat with the cooler in the air conditioning blower module 500 to increase its temperature, so as to absorb the heat in the air. The blower 530 blows the cooled air to the passenger compartment to facilitate the cooling of the passenger compartment.

[0185] Furthermore, through the setting of heat exchange branch 7, the coolant in heat exchange branch 7 can be heated at the refrigeration module 51 and then merge with the coolant in heat exchange circuit 6. It flows to the refrigerant integration module 600 to exchange heat with the second refrigerant and then cool down. This means that the second refrigerant does not need to flow through heat exchange branch 7. In this way, the second refrigerant can only flow in the refrigerant circuit 610, making it less likely that the second refrigerant will be blown into the passenger compartment of the new energy vehicle by the air conditioning blower module 500 when it leaks. This avoids the safety problems caused by the leakage of the second refrigerant and thus ensures the safety of the water-side integration module 100.

[0186] Thirdly, embodiments of this application provide a new energy vehicle, including a vehicle body and a thermal management integrated system 200 as described in the second aspect.

[0187] The vehicle body has a passenger compartment, and the blower 530 in the thermal management integrated system 200 is configured to blow the air after heat exchange with the cooling module 510 into the passenger compartment.
