[0002] As a crucial component of new power systems, the performance of the thermal management system (TMS) of energy storage devices directly determines the cycle life, safety, and overall operating efficiency of the battery pack. With the expansion of energy storage applications into extreme climate environments, the thermal management systems in related technologies still require improvement in terms of pipeline connection methods, space requirements, and ease of operation and maintenance.

[0003] Typically, thermal management systems in related technologies employ customized piping connection schemes, assembling core components via physical piping. This complex piping layout occupies significant space, reducing the space utilization of energy storage equipment and increasing the space required for containers or cabinets.

During the operation and maintenance phase, the numerous piping joints also increase the risk of leakage, consequently raising the difficulty of maintenance. Summary of the Invention

Detailed Implementation

[0023] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0024] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the thermal management integrated module of the energy storage device of this application.

[0025] In one embodiment, the thermal management integration module 20 of the energy storage device includes a water-side heat exchange module 21 and at least two sets of refrigerant-side heat exchange modules 22. For example... Figure 2 As shown, the energy storage device 10 also includes an energy storage converter 11 and a battery pack 12.

[0026] The water-side heat exchange module 21 is used to connect the energy storage converter 11 and the battery pack 12. The water-side heat exchange module 21 contains a first heat exchange medium, which can circulate between the water-side heat exchange module 21 and the energy storage converter 11 and between the water-side heat exchange module 21 and the battery pack 12 to exchange heat with at least one of the energy storage converter 11 and the battery pack 12.

[0027] The aforementioned at least two sets of refrigerant-side heat exchange modules 22 are respectively connected to opposite sides of the water-side heat exchange module 21. In this way, the connection flow paths between each set of refrigerant-side heat exchange modules 22 and the water-side heat exchange module 21 can be arranged on both sides of the water-side heat exchange module 21, avoiding problems such as flow path intersection and space congestion caused by all connection flow paths being concentrated on the same side of the water-side heat exchange module 21. Each set of refrigerant-side heat exchange modules 22 includes a refrigerant flow channel plate 224 and a compressor 221, a condenser 222, and an evaporator 223 disposed on the refrigerant flow channel plate 224. The compressor 221 is connected to the condenser 222 and the evaporator 223 respectively through flow channels within the refrigerant flow channel plate 224, and the condenser 222 and the evaporator 223 are also connected to the water-side heat exchange module 21 respectively through the refrigerant flow channel plate 224. Unlike the traditional method of connecting each component individually with external pipes, in this embodiment, the refrigerant flow channel plate 224 has internal flow channels. The outlet and inlet of compressor 221 are connected to condenser 222 and evaporator 223 respectively through corresponding flow channels inside refrigerant flow channel plate 224 to form a circulation loop for heat exchange medium (i.e., the second heat exchange medium). Furthermore, condenser 222 and evaporator 223 are also connected to water-side heat exchange module 21 through flow channels inside refrigerant flow channel plate 224, thus minimizing the need for external piping between refrigerant-side heat exchange module 22 and water-side heat exchange module 21.

[0028] In other words, by rationally setting the arrangement of at least two sets of refrigerant-side heat exchange modules 22 relative to the water-side heat exchange module 21, and coordinating the connection methods of the compressor 221, condenser 222, and evaporator 223 in each set of refrigerant-side heat exchange modules 22, as well as the connection methods between the refrigerant-side heat exchange module 22 and the water-side heat exchange module 21, this embodiment simplifies the piping structure of the thermal management integrated module 20. This firstly helps reduce the overall volume of the thermal management integrated module 20, improving the space utilization of the energy storage device 10, and thus reducing the space cost of containers or cabinets. Secondly, this embodiment avoids customized piping design, saving simulation, prototyping, and testing cycles, which helps shorten the R&D cycle of the energy storage device 10 and reduce R&D costs, enabling rapid response to the diverse market demands for energy storage devices 10 with different capacities (e.g., 2h, 4h, 8h) and different ratios. Furthermore, this embodiment has fewer pipe joints, reducing the risk of pipe leakage and helping to reduce maintenance difficulty and costs.

[0029] In this embodiment, the compressor 221 is configured to control the flow of the second heat exchange medium in the refrigerant-side heat exchange module 22 through the condenser 222 and the evaporator 223, so that the second heat exchange medium exchanges heat with the first heat exchange medium at the condenser 222 and the evaporator 223.

[0030] In this embodiment, the water-side heat exchange module 21 exchanges heat with at least one of the energy storage inverter 11 and the battery pack 12. The compressor 221 of each group of refrigerant-side heat exchange modules 22 exchanges heat with the water-side heat exchange module 21 through the condenser 222 and the evaporator 223, thereby achieving thermal management of the energy storage inverter 11 and the battery pack 12. The refrigerant-side heat exchange modules 22 in this embodiment can cooperate to achieve different thermal management modes, adapting to different thermal management modes and facilitating high-precision thermal management under different ambient temperatures. Furthermore, the method of heat exchange between the compressor 221 and the water-side heat exchange module 21 in this embodiment has high heat exchange efficiency.

[0031] It should be noted that this embodiment of the application uses two groups of refrigerant-side heat exchange modules 22 as an example. In other embodiments of this application, the number of refrigerant-side heat exchange modules 22 may also be three or more groups. By setting multiple groups of refrigerant-side heat exchange modules 22 and connecting them to the water-side heat exchange modules 21 respectively, the thermal management integrated module 20 can flexibly select the thermal management mode according to the ambient temperature conditions and the thermal management requirements of the energy storage converter 11 and the battery pack 12, to achieve high-precision thermal management, so that the operating temperature of the battery pack 12 and the energy storage converter 11 is maintained within a reasonable range, thereby ensuring the safe and efficient operation of the energy storage device 10.

[0032] And, as Figure 3 As shown, each group of refrigerant-side heat exchange modules 22 also includes an electromagnetic expansion valve 225. In each group of refrigerant-side heat exchange modules 22, the compressor 221, condenser 222, electromagnetic expansion valve 225, and evaporator 223 are connected in sequence to form a circulation loop. After the compressor 221 starts, it draws in the low-temperature, low-pressure gaseous second heat exchange medium and compresses it into a high-temperature, high-pressure gaseous second heat exchange medium, which is then discharged from the exhaust port. The high-temperature, high-pressure gaseous second heat exchange medium enters the condenser 222, where it exchanges heat with the first heat exchange medium flowing through the condensation flow path 214. The second heat exchange medium releases heat and condenses into a high-pressure liquid second heat exchange medium. After flowing out of the condenser 222, the high-pressure liquid second heat exchange medium enters the electromagnetic expansion valve 225. The electromagnetic expansion valve 225 throttles and reduces the pressure of the second heat exchange medium. The second heat exchange medium flowing through the electromagnetic expansion valve 225 enters the evaporator 223, where it exchanges heat with the first heat exchange medium flowing through the evaporation flow path 215, and then returns to the compressor 221, thus completing a complete refrigerant cycle.

[0033] like Figure 4As shown, when the thermal management integrated module 20 is correctly installed in the energy storage device 10, the thermal management integrated module 20 has intersecting vertical directions Z and horizontal directions X, specifically, the vertical direction Z and the horizontal direction X can be perpendicular to each other. The internal flow channels of the condenser 222 and the evaporator 223 extend along the horizontal direction X. As the core components for heat exchange in the refrigerant-side heat exchange module 22, the extension direction of the internal flow channels of the condenser 222 and the evaporator 223 directly affects the flow state and distribution uniformity of the second heat exchange medium in the flow channels. Setting the internal flow channels of the condenser 222 and the evaporator 223 to extend along the horizontal direction X can make the second heat exchange medium maintain a relatively uniform distribution in the direction of gravity when flowing through the condenser 222 or the evaporator 223. If the internal flow channels of the condenser 222 and the evaporator 223 are inclined relative to the horizontal direction X, it will cause differences in flow resistance at different positions in the flow channels, and may lead to gas blockage in the second heat exchange medium during vaporization. The horizontally extended flow channel in this embodiment can reduce the uneven distribution of the second heat exchange medium in the flow channel and the air blockage caused by gravity, which is conducive to making the second heat exchange medium more evenly distributed in the condenser 222 and evaporator 223, reducing flow resistance, and thus improving heat exchange efficiency.

[0034] In one embodiment, the compressor 221, condenser 222, and evaporator 223 of each group of refrigerant-side heat exchange modules 22 are all located on the side of their respective refrigerant flow channel plates 224 facing away from the water-side heat exchange module 21. The side of the refrigerant flow channel plates 224 of each group of refrigerant-side heat exchange modules 22 facing the water-side heat exchange module 21 is connected to the water-side heat exchange module 21 via a connecting pipe 60, thereby connecting the condenser 222 and evaporator 223 of each group of refrigerant-side heat exchange modules 22 to the water-side heat exchange module 21. The compressor 221, condenser 222, and evaporator 223 of each group of refrigerant-side heat exchange modules 22 are centrally arranged on the same side of their respective refrigerant flow channel plates 224. The other side of the refrigerant flow channel plates 224 of each group of refrigerant-side heat exchange modules 22 faces the water-side heat exchange module 21, for connection with the water-side heat exchange module 21. This embodiment clearly defines the functional division of the two sides of the refrigerant flow channel plate 224. One side is used to install the compressor 221, condenser 222, and evaporator 223, while the other side is used to connect to the water-side heat exchange module 21. This allows for a more compact structure of the refrigerant-side heat exchange module 22, thereby reducing the overall size of the thermal management integrated module 20. Furthermore, with the compressor 221, condenser 222, and evaporator 223 concentrated on the same side of the refrigerant flow channel plate 224, the electrical wiring connecting the compressor 221, condenser 222, and evaporator 223 can also be led out and centrally arranged from the same side of the refrigerant flow channel plate 224, simplifying wiring routing and reducing wiring difficulty.

[0035] In one embodiment, the compressor 221, condenser 222, and evaporator 223 of each group of refrigerant-side heat exchange modules 22 are distributed along the height direction Z of the thermal management integrated module 20. This fully utilizes the space of the thermal management integrated module 20 in the height direction Z, reducing the space occupied by the refrigerant-side heat exchange modules 22 in the horizontal direction X, thereby reducing the size of the thermal management integrated module 20 in the horizontal direction X. This is particularly advantageous for energy storage devices 10, which typically have limited space in the horizontal direction X, as it allows for more horizontal arrangement space for other components inside the energy storage device 10 (such as the battery pack 12 and the energy storage converter 11), thus improving the overall space utilization rate of the energy storage device 10.

[0036] Please refer to the following: Figure 4 and Figure 5 In one embodiment, the water-side heat exchange module 21 includes a water-side flow channel plate 218 and at least two sets of water-side heat exchange components 211. The water-side flow channel plate 218 is connected to the refrigerant flow channel plate 224 of each refrigerant-side heat exchange module 22. The at least two sets of water-side heat exchange components 211 are respectively connected to opposite sides of the water-side flow channel plate 218, and each water-side heat exchange component 211 is connected to the condenser 222 and evaporator 223 of the corresponding refrigerant-side heat exchange module 22. The aforementioned height direction Z and horizontal direction X are both parallel to the surface of the water-side heat exchange components 211 disposed on the water-side flow channel plate 218.

[0037] The water-side flow channel plate 218 has internal flow channels. Each water-side heat exchange component 211 is connected to the condenser 222 and evaporator 223 of the corresponding refrigerant-side heat exchange module 22 through the flow channels inside the water-side flow channel plate 218. The number of water-side heat exchange components 211 corresponds to the number of refrigerant-side heat exchange modules 22. Taking two groups of refrigerant-side heat exchange modules 22 as an example, when there are two groups of refrigerant-side heat exchange modules 22, there are also two groups of water-side heat exchange components 211. These two groups of water-side heat exchange components 211 are respectively arranged on the left and right sides of the water-side flow channel plate 218, and each group of water-side heat exchange components 211 is adjacent to the corresponding refrigerant-side heat exchange module 22 and arranged on the same side of the water-side flow channel plate 218. The refrigerant-side heat exchange module 22 located on the left side of the water-side flow channel plate 218 is connected to the water-side heat exchange assembly 211 on the same side, and the refrigerant-side heat exchange module 22 located on the right side of the water-side flow channel plate 218 is connected to the water-side heat exchange assembly 211 on the same side. Each set of water-side heat exchange assemblies 211 is connected to the condenser 222 and evaporator 223 in the corresponding refrigerant-side heat exchange module 22 on the same side.

[0038] In this embodiment, each group of water-side heat exchange components 211 is arranged on both sides of the water-side flow channel plate 218 and connected to the corresponding refrigerant-side heat exchange module 22. The connection flow paths between each group of water-side heat exchange components 211 and the corresponding refrigerant-side heat exchange module 22 can be arranged on the left and right sides of the water-side flow channel plate 218, avoiding the problems of flow path intersection and space congestion caused by all connection flow paths being concentrated on the same side of the water-side flow channel plate 218. This helps to make the internal spatial layout of the water-side heat exchange module 21 more regular and compact, thereby further reducing the overall volume of the thermal management integrated module 20.

[0039] For example, the at least two sets of refrigerant-side heat exchange modules 22 mentioned above include a first refrigerant-side heat exchange module 22a and a second refrigerant-side heat exchange module 22b. The at least two sets of water-side heat exchange components 211 mentioned above include a first water-side heat exchange component 211a and a second water-side heat exchange component 211b. The first water-side heat exchange component 211a is disposed on one side of the water-side flow channel plate 218, and the second water-side heat exchange component 211b is disposed on the other side of the water-side flow channel plate 218. The first water-side heat exchange component 211a is connected to the condenser 222 and evaporator 223 of the first refrigerant-side heat exchange module 22a, and the second water-side heat exchange component 211b is connected to the condenser 222 and evaporator 223 of the second refrigerant-side heat exchange module 22b. That is, each set of refrigerant-side heat exchange modules 22 corresponds to one set of water-side heat exchange components 211.

[0040] Specifically, each water-side heat exchange assembly 211 includes a first conductive element 212, a second conductive element 213, a condensation flow path 214, an evaporation flow path 215, and an air-cooling flow path 216.

[0041] The first conductive element 212 is used to connect to the energy storage converter 11. Specifically, the first conductive element 212 has a port communicating with the energy storage converter 11, through which the first heat exchange medium flows into or out of the energy storage converter 11. The second conductive element 213 is used to connect to the battery pack 12. The second conductive element 213 has a port communicating with the battery pack 12, through which the first heat exchange medium flows into or out of the battery pack 12. The first conductive element 212 and the second conductive element 213, belonging to the same group of water-side heat exchange components 211, are disposed on the same side of the water-side flow channel plate 218.

[0042] The condenser flow path 214 is disposed inside the water-side flow channel plate 218 and is connected to the first conductive element 212 and the second conductive element 213 respectively. The condenser flow path 214 is connected to the condenser 222 of the corresponding refrigerant-side heat exchange module 22, allowing the first heat exchange medium to pass through. When the first heat exchange medium flows through the condenser flow path 214, the heat released by the second heat exchange medium in the condenser 222 is transferred to the first heat exchange medium in the condenser flow path 214. Further, the condenser flow path 214 is provided with a first pump body 2141, which is used to pump the first heat exchange medium through the condenser flow path 214 and then through the condenser 222.

[0043] An evaporation flow path 215 is disposed inside the water-side flow channel plate 218 and is connected to the first conductive element 212 and the second conductive element 213 respectively. The evaporation flow path 215 is connected to the evaporator 223 of the corresponding refrigerant-side heat exchange module 22, allowing the first heat exchange medium to pass through. When the first heat exchange medium flows through the evaporation flow path 215, the heat of the first heat exchange medium in the evaporation flow path 215 is transferred to the second heat exchange medium in the evaporator 223. Furthermore, the evaporation flow path 215 is provided with a second pump body 2151, which is used to pump the first heat exchange medium through the evaporation flow path 215 and then through the evaporator 223.

[0044] An air-cooled flow path 216 is disposed inside the water-side flow channel plate 218 and connected to the first conductive element 212 and the second conductive element 213 respectively. An air cooler 217 is provided in the air-cooled flow path 216, disposed outside the water-side flow channel plate 218 and connected to the air-cooled flow path 216. The air cooler 217 can be an air-cooled heat exchanger, etc., and its interior is used for heat exchange with the outside air through the first heat exchange medium. When the first heat exchange medium flows through the air-cooled flow path 216, heat exchange with the ambient air can occur through the air cooler 217. When the ambient temperature is low, the air cooler 217 can dissipate the heat in the first heat exchange medium into the environment, achieving cooling of the first heat exchange medium; when the ambient temperature is high or active cooling is not required, the air cooler 217 can also serve as an auxiliary heat dissipation method.

[0045] It should be noted that the first conducting element 212 and the second conducting element 213 each have multiple ports, and the two ends of the condensing flow path 214, the evaporating flow path 215, and the air-cooling flow path 216 are respectively connected to the ports of the first conducting element 212 and the second conducting element 213. By changing the valve core position or port connection relationship inside the first conducting element 212 and the second conducting element 213, at least one of the condensing flow path 214, the evaporating flow path 215, and the air-cooling flow path 216 can be selectively connected to the energy storage converter 11 or the battery pack 12.

[0046] Through the cooperation of the first conductive element 212 and the second conductive element 213, the first heat exchange medium can form different flow paths between the energy storage converter 11, the battery pack 12, and the condensation flow path 214, the evaporation flow path 215, and the air-cooling flow path 216. Based on this, the thermal management integrated module 20 in this embodiment can achieve multiple thermal management modes without changing the flow direction of the second heat exchange medium in the refrigerant-side heat exchange module 22, enabling flexible switching between different thermal management modes and improving the integration and operational flexibility of the thermal management integrated module 20. When switching thermal management modes is required, the flow direction of the first heat exchange medium is changed through the first conductive element 212 and / or the second conductive element 213, while the circulation direction of the second heat exchange medium remains fixed. This avoids the need to install a four-way reversing valve on the refrigerant side to switch the refrigerant flow direction, simplifies the piping structure of the refrigerant-side heat exchange module 22, helps reduce the risk of leakage of the second heat exchange medium, and improves system reliability.

[0047] Optionally, both the first conducting element 212 and the second conducting element 213 can be conducting elements such as a six-way valve. The six-way valve has a rotatable valve core inside; by driving the valve core to rotate to different angles, different conducting combinations between its multiple ports can be achieved. In other embodiments of this application, the first conducting element 212 and the second conducting element 213 can also be a valve group composed of multiple switching valves, which can selectively connect each flow path to the energy storage converter 11 or the battery pack 12.

[0048] In one embodiment, the first pump body 2141 and the second pump body 2151 belonging to the same water-side heat exchange assembly 211 are disposed on the same side of the water-side flow channel plate 218. In this embodiment, the first pump body 2141 and the second pump body 2151 corresponding to each water-side heat exchange assembly 211 are centrally arranged on the same side of the water-side flow channel plate 218, rather than being dispersed on different sides of the water-side flow channel plate 218. The relatively concentrated spatial position of the first pump body 2141 and the second pump body 2151 of the same water-side heat exchange assembly 211 helps to reduce the complexity of the flow path structure and further simplifies the piping structure of the thermal management integrated module 20.

[0049] With two sets of water-side heat exchange components 211 positioned on opposite sides of the water-side flow channel plate 218, the first water-side heat exchange component 211a is arranged on the left side of the water-side flow channel plate 218, with the first pump body 2141 and the second pump body 2151 of the first water-side heat exchange component 211a concentrated on the left side of the water-side flow channel plate 218; the second water-side heat exchange component 211b is arranged on the right side of the water-side flow channel plate 218, with the first pump body 2141 and the second pump body 2151 of the second water-side heat exchange component 211b concentrated on the right side of the water-side flow channel plate 218. This arrangement ensures that the first water-side heat exchange components 211a and the second water-side heat exchange components 211b are symmetrically distributed on both sides of the water-side flow channel plate 218, which helps to improve the overall compactness of the thermal management integrated module 20.

[0050] In one embodiment, in each group of water-side heat exchange components 211, the first conducting element 212 and the second conducting element 213 are distributed along the height direction Z, and the first pump body 2141 and the second pump body 2151 are distributed along the height direction Z. The first conducting element 212 and the second conducting element 213 are distributed along the horizontal direction X, as are the first pump body 2141 and the second pump body 2151. Specifically, on the same side of the water-side flow channel plate 218, the first conducting element 212 and the second conducting element 213 are arranged in a first vertical column, and the first pump body 2141 and the second pump body 2151 are arranged in a second vertical column. The first vertical column and the second vertical column are spaced apart from each other along the horizontal direction X. That is, the side is divided into two functional areas in the horizontal direction X: one functional area concentrates the arrangement of the first conducting element 212 and the second conducting element 213, and the other functional area concentrates the arrangement of the first pump body 2141 and the second pump body 2151.

[0051] In this embodiment, all components on the same side of the water-side flow channel plate 218 are arranged in an orderly manner in both the vertical Z and horizontal X directions, avoiding the space congestion caused by densely arranging all components in the same direction. By partitioning the conductive components and pump body in the horizontal X direction, this embodiment ensures a moderate number of components in each functional area, providing ample operating space for the installation of each component and pipeline connection, thus reducing assembly difficulty. During maintenance, operators can inspect the conductive components or pump body separately in different areas of the horizontal X direction. The maintenance operations in different functional areas are separated in the horizontal X direction, without interference, which improves maintenance efficiency.

[0052] In one embodiment, the water-side heat exchange module 21 further includes a first interface group 30 and a second interface group 40. The first interface group 30 is disposed on one side of the water-side flow channel plate 218. The first interface group 30, the first conductive element 212, and the second conductive element 213 are respectively located on different sides of the water-side flow channel plate 218. The first interface group 30 is used to connect the energy storage converter 11 to the first conductive element 212 of each group of water-side heat exchange components 211. The first interface group 30 is used for the energy storage converter 11 to access the system; on the other hand, it is connected to the first conductive element 212 through the flow path inside the water-side flow channel plate 218, so that the energy storage converter 11 can be connected to the heat exchange loop of the thermal management integrated module 20 via the first interface group 30. The second interface group 40 is disposed on one side of the water-side flow channel plate 218. The second interface group 40, the first conductive element 212, and the second conductive element 213 are respectively located on different sides of the water-side flow channel plate 218. The second interface group 40 is used to connect the battery pack 12 to the second conductive element 213 of each group of water-side heat exchange components 211. The second interface group 40 is used for the battery pack 12 to access the system; on the other hand, it is connected to the second conductive element 213 through the flow path inside the water-side flow channel plate 218, so that the battery pack 12 can be connected to the heat exchange loop of the thermal management integrated module 20 via the second interface group 40.

[0053] In this embodiment, by distributing the first interface group 30 and the second interface group 40, along with the first conductive element 212 and the second conductive element 213, on different sides of the water-side flow channel plate 218, different working surfaces of the water-side flow channel plate 218 each assume different functional roles. One working surface is used to centrally arrange the components of the water-side heat exchange assembly 211, such as the first conductive element 212 and the second conductive element 213, while the other working surface is used to centrally arrange the interface groups for external connections. On the one hand, the components of the water-side heat exchange assembly 211 and each interface group are spatially separated, and their respective working surfaces can be independently optimized for layout. This helps to avoid the components of the water-side heat exchange assembly 211 and each interface group crowding each other on the same side of the water-side flow channel plate 218, making the component arrangement on each side of the water-side flow channel plate 218 clearer and more orderly, and reducing the difficulty of layout. On the other hand, since the components and interface groups of the water-side heat exchange assembly 211 are located on different sides of the water-side flow channel plate 218, the operators can perform the insertion and removal operations of each interface group and the maintenance operations of the components of the water-side heat exchange assembly 211 on different sides of the water-side flow channel plate 218 during assembly or maintenance, without interfering with each other, which is conducive to improving assembly efficiency and maintenance convenience.

[0054] Furthermore, the first interface group 30 and the second interface group 40 can be located on the same side of the water-side flow channel plate 218. In this way, the connecting pipes 60 of the energy storage converter 11 and the battery pack 12 are all led out from the same side of the water-side flow channel plate 218, which facilitates the layout and routing of pipes inside the energy storage device 10 and avoids problems such as low space utilization and complex pipe structure caused by the external pipes extending from different sides of the thermal management integrated module 20.

[0055] For example, the first interface group 30 includes a first energy storage converter interface 31 and a second energy storage converter interface 32. The first conducting element 212 of one group of water-side heat exchange components 211 is connected to the first energy storage converter interface 31 through a corresponding flow path inside the water-side flow channel plate 218, and is connected to the energy storage converter 11 through the first energy storage converter interface 31; the first conducting element 212 of the other group of water-side heat exchange components 211 is connected to the second energy storage converter interface 32 through a corresponding flow path inside the water-side flow channel plate 218, and is connected to the energy storage converter 11 through the second energy storage converter interface 32.

[0056] The second interface group 40 includes a first battery pack interface 41 and a second battery pack interface 42. The second conductive element 213 of one set of water-side heat exchange components 211 is connected to the first battery pack interface 41 through a corresponding flow path inside the water-side flow channel plate 218, and is connected to the battery pack 12 through the first battery pack interface 41; the second conductive element 213 of the other set of water-side heat exchange components 211 is connected to the second battery pack interface 42 through a corresponding flow path inside the water-side flow channel plate 218, and is connected to the battery pack 12 through the second battery pack interface 42.

[0057] In one embodiment, the water-side heat exchange module 21 further includes at least two sets of air cooler interface groups 50. These at least two sets of air cooler interface groups 50 are disposed on the same side of the water-side flow channel plate 218, and are located on different sides of the water-side flow channel plate 218, respectively, as well as the first conductive element 212 and the second conductive element 213. Each air cooler interface group 50 is used to connect the air cooler 217 in the corresponding water-side heat exchange component 211 to the air-cooled flow path 216. Each air cooler interface group 50 communicates with the air-cooled flow path 216 of the corresponding water-side heat exchange component 211 through the flow path inside the water-side flow channel plate 218, and is also used to allow the air cooler 217 to access, thereby connecting the air cooler 217 to the heat exchange loop of the thermal management integrated module 20.

[0058] The number of air cooler interface groups 50 corresponds to the number of water-side heat exchange components 211. Taking the above-mentioned water-side heat exchange components 211 as an example with two groups, the air cooler interface groups 50 are also set to two groups. These two groups of air cooler interface groups 50 are located on the same side of the water-side flow channel plate 218.

[0059] In this embodiment, each air cooler interface group 50, the first conductive element 212, and the second conductive element 213 are respectively disposed on different sides of the water-side flow channel plate 218, so that the air cooler interface group 50, the first conductive element 212, and the second conductive element 213 are respectively located on different working surfaces of the water-side flow channel plate 218. The components of the water-side heat exchange assembly 211 (i.e., the first conductive element 212 and the second conductive element 213) are concentrated on one working surface of the water-side flow channel plate 218, and the air cooler interface group 50 for connecting with the air cooler 217 is concentrated on the other working surface of the water-side flow channel plate 218. The aforementioned functional zoning arrangement serves two purposes. First, it avoids the components of the air cooler interface group 50 and the water-side heat exchange assembly 211 from encroaching on each other on the same side of the water-side flow channel plate 218, making the component arrangement on each side of the water-side flow channel plate 218 clearer and more orderly, and reducing the difficulty of installation. Second, as the air cooler 217 is a component that needs to exchange heat with the outside air, its corresponding interface and the components of the water-side heat exchange assembly 211 are arranged on different sides of the water-side flow channel plate 218. This allows the air cooler 217 to obtain more ample space on the outside of the water-side flow channel plate 218, preventing the components of the water-side heat exchange assembly 211 from affecting the air cooler 217, thereby ensuring the normal operation of the air cooler 217. Furthermore, during assembly or maintenance, the insertion and removal operations of the air cooler interface group 50 and the maintenance operations of the components of the water-side heat exchange assembly 211 can be performed separately on different sides of the water-side flow channel plate 218 without interference, which improves assembly efficiency and maintenance convenience.

[0060] It should be noted that the first interface group 30 and the second interface group 40 are arranged on one side of the water-side flow channel plate 218, each air cooler interface group 50 is arranged on the other side of the water-side flow channel plate 218, and the first conductive element 212 and the second conductive element 213 of each water-side heat exchange assembly 211 are arranged on the other sides of the water-side flow channel plate 218. That is to say, the aforementioned components of different functional types are arranged on different sides of the water-side flow channel plate 218. For example, the first conductive element 212 and the second conductive element 213 of each water-side heat exchange assembly 211 are arranged on two opposite large surfaces of the water-side flow channel plate 218, the first interface group 30 and the second interface group 40 are arranged on one side of the water-side flow channel plate 218 adjacent to this large surface, and each air cooler interface group 50 is arranged on the other side of the water-side flow channel plate 218 adjacent to this large surface. Since the temperature of the first heat exchange medium flowing through the battery pack 12 is different from the temperature of the first heat exchange medium flowing through the air cooler 217, the second interface group 40 and the air cooler interface group 50 are arranged on different sides of the water-side flow channel plate 218 in this embodiment, which can reduce the risk of heat leakage between the battery pack 12 and the air cooler 217.

[0061] In this embodiment, multiple surfaces of the water-side flow channel plate 218 are fully utilized. The first interface group 30 and the second interface group 40, each air cooler interface group 50, and the first conductive element 212 and the second conductive element 213 of each water-side heat exchange component 211 are arranged on different sides of the water-side flow channel plate 218 according to their own connection direction requirements and space requirements, thus avoiding space congestion and mutual interference caused by them being gathered on the same side of the water-side flow channel plate 218.

[0062] The following describes the different thermal management modes of the thermal management integrated module 20 in the embodiments of this application.

[0063] In one embodiment, please refer to Figure 6 The thermal management integrated module 20 has a first heat dissipation mode. The first heat dissipation mode is suitable for operating conditions with high ambient temperatures.

[0064] Specifically, in the first heat dissipation mode, the evaporation path 215 of the first water-side heat exchange component 211a, the evaporation path 215 of the second water-side heat exchange component 211b, and the battery pack 12 are connected in series. After the first heat exchange medium flows out of the battery pack 12, it flows sequentially through the evaporation path 215 of the first water-side heat exchange component 211a and the evaporation path 215 of the second water-side heat exchange component 211b, and then returns to the battery pack 12. During this process, the first heat exchange medium exchanges heat with the evaporator 223 of the refrigerant-side heat exchange module 22, and the heat from the first heat exchange medium is transferred to the second heat exchange medium in the evaporator 223, where it is cooled. The cooled first heat exchange medium returns to the battery pack 12, absorbing heat from the battery pack 12, thus achieving cyclic cooling of the battery pack 12.

[0065] The compressor 221 of the first refrigerant-side heat exchange module 22a and / or the compressor 221 of the second refrigerant-side heat exchange module 22b controls the second heat exchange medium to dissipate heat from the first heat exchange medium. The compressor 221 of the first refrigerant-side heat exchange module 22a and / or the compressor 221 of the second refrigerant-side heat exchange module 22b are started. The compressor 221 drives the second heat exchange medium to circulate within its respective refrigerant-side heat exchange module 22. The second heat exchange medium absorbs heat from the first heat exchange medium at the evaporator 223 to cool the first heat exchange medium, and then cools the battery pack 12 through the low-temperature first heat exchange medium.

[0066] Furthermore, in the first heat dissipation mode, the condensation path 214 and air-cooling path 216 of the first water-side heat exchange component 211a, the energy storage converter 11, and the condensation path 214 and air-cooling path 216 of the second water-side heat exchange component 211b are connected in series. After the first heat exchange medium flows out of the energy storage converter 11, it flows sequentially through the condensation path 214 and air-cooling path 216 of the first water-side heat exchange component 211a, the condensation path 214 and air-cooling path 216 of the second water-side heat exchange component 211b, and then returns to the energy storage converter 11. During this process, the first heat exchange medium carries the heat generated during the operation of the energy storage converter 11 to the air cooler 217, where the air cooler 217 exchanges heat with the external environment, thus dissipating heat from the energy storage converter 11. The series arrangement of the two sets of air-cooling paths 216 is beneficial to improving the heat dissipation effect on the energy storage converter 11. The heat absorbed by the first heat exchange medium at the condenser 222 is then dissipated to the external environment as it flows through the air cooler 217, thus not affecting the heat dissipation effect of the energy storage converter 11.

[0067] Furthermore, such as Figure 6 As shown, when the ambient temperature is within the first temperature range, the compressor 221 of the first refrigerant-side heat exchange module 22a and the compressor 221 of the second refrigerant-side heat exchange module 22b control the second heat exchange medium to dissipate heat from the first heat exchange medium. Figure 7 and Figure 8 As shown, when the ambient temperature is within the second temperature range, the compressor 221 of the first refrigerant-side heat exchange module 22a or the compressor 221 of the second refrigerant-side heat exchange module 22b controls the second heat exchange medium to dissipate heat from the first heat exchange medium. The temperature in the first temperature range is higher than the temperature in the second temperature range.

[0068] like Figure 6 As shown, when the ambient temperature is within the first temperature range, for example, between 45°C and 55°C, the battery pack 12 requires a larger cooling capacity. At this time, the compressors 221 of the first refrigerant-side heat exchange module 22a and the second refrigerant-side heat exchange module 22b simultaneously start operating, and both sets of refrigerant-side heat exchange modules 22 work concurrently to provide cooling capacity to the battery pack 12. The two evaporators 223 simultaneously exchange heat with the first heat exchange medium, increasing the temperature drop obtained by the first heat exchange medium flowing through the battery pack 12. In this embodiment, the simultaneous operation of the first refrigerant-side heat exchange module 22a and the second refrigerant-side heat exchange module 22b can provide greater cooling capacity to meet the heat dissipation requirements under extremely high temperature environments.

[0069] like Figure 7 and Figure 8As shown, when the ambient temperature is in the second temperature range, for example, between 35°C and 45°C, the cooling capacity required by the battery pack 12 is relatively small. At this time, the compressor 221 of either the first refrigerant-side heat exchange module 22a or the second refrigerant-side heat exchange module 22b is activated, meaning one of the two sets of refrigerant-side heat exchange modules 22 is started, and this set of modules independently provides the cooling capacity. In this embodiment, when the ambient temperature is relatively low, cooling the battery pack 12 by activating one set of refrigerant-side heat exchange modules 22 reduces the power consumption of the thermal management integrated module 20, improving operational economy while meeting heat dissipation requirements. Figure 7 This demonstrates the start-up and operation of compressor 221 in the first refrigerant-side heat exchange module 22a. Figure 8 The compressor 221 of the second refrigerant-side heat exchange module 22b is shown to be in operation.

[0070] Understandably, when the ambient temperature is within the second temperature range, the compressor 221 of the first refrigerant-side heat exchange module 22a and the compressor 221 of the second refrigerant-side heat exchange module 22b can operate alternately. Specifically, the thermal management integrated module 20 can be set with an alternation cycle, for example, switching every 2 hours. After the compressor 221 of the first refrigerant-side heat exchange module 22a has run for 2 hours, it is shut down, and the compressor 221 of the second refrigerant-side heat exchange module 22b is started and continues to run; after the compressor 221 of the second refrigerant-side heat exchange module 22b has run for 2 hours, it is shut down, and the compressor 221 of the first refrigerant-side heat exchange module 22a is restarted, and so on, alternating in this cycle. By alternating the operation of the compressor 221 of the first refrigerant-side heat exchange module 22a and the compressor 221 of the second refrigerant-side heat exchange module 22b, it is beneficial to extend the service life of the compressor 221 and the overall maintenance cycle of the thermal management integrated module 20. Furthermore, during the operation of the compressor 221 of one set of refrigerant-side heat exchange modules 22, there is no refrigerant circulation in the evaporator 223 and condenser 222 of the other set of refrigerant-side heat exchange modules 22 that are not started. When the first heat exchange medium flows through the corresponding flow path of the unstarted refrigerant-side heat exchange module 22, it only serves as a channel and does not participate in active heat exchange.

[0071] Furthermore, the first temperature range can be set to 45℃ to 55℃, and the second temperature range can be set to 35℃ to 45℃. The temperature ranges of the first and second temperature ranges can be adaptively adjusted according to the actual heat dissipation requirements of the energy storage device 10 and the performance of the refrigerant-side heat exchange module 22.

[0072] In this embodiment, by connecting the battery pack 12 in series with the evaporation flow path 215 of the two sets of water-side heat exchange components 211 in the first heat dissipation mode, and connecting the energy storage converter 11 in series with the condensation flow path 214 and air-cooling flow path 216 of the two sets of water-side heat exchange components 211, and coordinating with the combined control of the compressors 221 of the two sets of refrigerant-side heat exchange modules 22, efficient heat dissipation under high-temperature environments is achieved. Simultaneously, by selecting whether the compressors 221 of the two sets of refrigerant-side heat exchange modules 22 operate simultaneously or only one set of compressors 221 according to the ambient temperature, the thermal management integrated module 20 can provide matching cooling capacity under different ambient temperature conditions, achieving high-precision thermal management of the battery pack 12 and the energy storage converter 11, while also considering the operating life and energy economy of the thermal management integrated module 20.

[0073] In one embodiment, please refer to Figure 9 and Figure 10 The thermal management integrated module 20 has a second heat dissipation mode. This second heat dissipation mode is suitable for operating conditions with moderate ambient temperatures (e.g., 10°C to 35°C). In this second heat dissipation mode, one of the energy storage converter 11 and the battery pack 12 is connected to the air-cooled flow path 216 of the first water-side heat exchange component 211a, and the other is connected to the air-cooled flow path 216 of the second water-side heat exchange component 211b. In this embodiment, in the second heat dissipation mode, the battery pack 12 and the energy storage converter 11 are cooled by utilizing the natural cold source in the external environment through the air-cooled flow path 216. At this time, the compressor 221 of the refrigerant-side heat exchange module 22 is in a stopped state.

[0074] Specifically, based on the different heat dissipation requirements of the battery pack 12 and the energy storage converter 11, the second heat dissipation mode can be further divided into two sub-modes, namely the first sub-mode and the second sub-mode, and the switching of the flow path is controlled by the first conducting element 212 and the second conducting element 213 to realize the switching of the first sub-mode and the second sub-mode.

[0075] like Figure 9As shown, in the first sub-mode, the evaporation path 215 and the air-cooling path 216 of the first water-side heat exchange component 211a are connected in series with the battery pack 12. The condensation path 214 of the first water-side heat exchange component 211a and the condensation path 214, evaporation path 215, and air-cooling path 216 of the second water-side heat exchange component 211b are connected in series with the energy storage converter 11. After the first heat exchange medium flows out of the energy storage converter 11, it flows sequentially through the condensation path 214 of the first water-side heat exchange component 211a, the evaporation path 215 of the second water-side heat exchange component 211b, the air-cooling path 216 of the second water-side heat exchange component 211b, and the condensation path 214 of the second water-side heat exchange component 211b, and then returns to the energy storage converter 11. The external environment cools the first heat exchange medium at the air cooler 217 of the second water-side heat exchange component 211b, thereby cooling the energy storage converter 11. Since the compressor 221 of the refrigerant-side heat exchange module 22 is not operating, the first heat exchange medium does not exchange heat with the second heat exchange medium as it flows through the condensation path 214 of the first water-side heat exchange component 211a, the condensation path 214 of the second water-side heat exchange component 211b, and the evaporation path 215. After flowing out of the battery pack 12, the first heat exchange medium flows sequentially through the evaporation path 215 and the air-cooling path 216 of the first water-side heat exchange component 211a, and then returns to the battery pack 12. The external environment cools the first heat exchange medium at the air cooler 217 of the first water-side heat exchange component 211a, thereby cooling the battery pack 12. Since the compressor 221 of the refrigerant-side heat exchange module 22 is in a stopped state, the first heat exchange medium does not exchange heat with the second heat exchange medium when flowing through the evaporation path 215 of the first water-side heat exchange component 211a. In this mode, the condensation path 214 of the first water-side heat exchange component 211a and the condensation path 214, evaporation path 215, and air-cooling path 216 of the second water-side heat exchange component 211b work together to dissipate heat from the energy storage converter 11, so that the flow rate of the first heat exchange medium flowing through the energy storage converter 11 is greater than the flow rate of the first heat exchange medium flowing through the battery pack 12, thereby improving the heat dissipation effect of the energy storage converter 11 and meeting the heat dissipation requirements of the energy storage converter 11.

[0076] like Figure 10As shown, in the second sub-mode, the condensation path 214, evaporation path 215, and air-cooling path 216 of the first water-side heat exchange component 211a, and the condensation path 214 of the second water-side heat exchange component 211b are connected in series with the battery pack 12. The evaporation path 215 and air-cooling path 216 of the second water-side heat exchange component 211b are connected in series with the energy storage converter 11. After the first heat exchange medium flows out of the battery pack 12, it flows sequentially through the evaporation path 215 of the first water-side heat exchange component 211a, the air-cooling path 216 of the first water-side heat exchange component 211a, the condensation path 214 of the first water-side heat exchange component 211a, and the condensation path 214 of the second water-side heat exchange component 211b, and then returns to the battery pack 12. The external environment cools the first heat exchange medium at the air cooler 217 of the first water-side heat exchange component 211a, thereby dissipating heat and cooling the battery pack 12. Since the compressor 221 of the refrigerant-side heat exchange module 22 is in a stopped state, the first heat exchange medium does not exchange heat with the second heat exchange medium when flowing through the condensation path 214 and evaporation path 215 of the first water-side heat exchange component 211a and the condensation path 214 of the second water-side heat exchange component 211b. After flowing out of the energy storage converter 11, the first heat exchange medium flows sequentially through the evaporation path 215 and the air-cooling path 216 of the second water-side heat exchange component 211b, and then returns to the energy storage converter 11. The external environment cools the first heat exchange medium at the air cooler 217 of the second water-side heat exchange component 211b, thereby dissipating heat and cooling the energy storage converter 11. Since the compressor 221 of the refrigerant-side heat exchange module 22 is in a stopped state, the first heat exchange medium does not exchange heat with the second heat exchange medium when flowing through the evaporation path 215 of the second water-side heat exchange component 211b. In this mode, the condensation flow path 214, evaporation flow path 215, and air-cooling flow path 216 of the first water-side heat exchange component 211a, and the condensation flow path 214 of the second water-side heat exchange component 211b work together to dissipate heat from the battery pack 12, so that the flow rate of the first heat exchange medium flowing through the battery pack 12 is greater than the flow rate of the first heat exchange medium flowing through the energy storage converter 11, thereby improving the heat dissipation effect of the battery pack 12 and meeting the heat dissipation requirements of the battery pack 12.

[0077] In this embodiment, under the second heat dissipation mode, the thermal management integrated module 20 relies on the air cooler 217 to utilize natural cold sources to dissipate heat from the energy storage converter 11 and the battery pack 12, while the compressor 221 is in a stopped state, which helps reduce the operating energy consumption of the thermal management integrated module 20. Simultaneously, by switching the conduction states of the first conducting element 212 and the second conducting element 213, the flow distribution of the first heat exchange medium between the battery pack 12 and the energy storage converter 11 can be flexibly adjusted, thereby matching the heat dissipation requirements of the battery pack 12 and the energy storage converter 11, which is beneficial for achieving high-precision thermal management of the battery pack 12 and the energy storage converter 11.

[0078] In one embodiment, please refer to Figure 11 The thermal management integrated module 20 has a heating mode. This heating mode is suitable for operating conditions with low ambient temperatures. In this mode, the thermal management integrated module 20 generates heat by activating the compressor 221 to increase the temperature of the battery pack 12, ensuring its charge / discharge performance and cycle life in low-temperature environments. The energy storage converter 11 is a power device, and it typically does not require heating. Therefore, this embodiment uses the heating requirement of the battery pack 12 as an example. In the heating mode, the energy storage converter 11 is not connected to the thermal management integrated module 20.

[0079] Specifically, in heating mode, the condensation path 214 of the first water-side heat exchange component 211a and the condensation path 214 of the second water-side heat exchange component 211b are connected in series with the battery pack 12; the evaporation path 215 and the air-cooling path 216 of the first water-side heat exchange component 211a are connected, and the evaporation path 215 and the air-cooling path 216 of the second water-side heat exchange component 211b are connected. The compressor 221 of the first refrigerant-side heat exchange module 22a and / or the compressor 221 of the second refrigerant-side heat exchange module 22b controls the second heat exchange medium to heat the first heat exchange medium, thereby heating the battery pack 12.

[0080] After flowing out of the battery pack 12, the first heat exchange medium flows sequentially through the condensation path 214 of the first water-side heat exchange component 211a and the condensation path 214 of the second water-side heat exchange component 211b, and then returns to the battery pack 12. While flowing through each condensation path 214, the first heat exchange medium exchanges heat with the condenser 222 of the corresponding refrigerant-side heat exchange module 22, absorbing the heat released by the second heat exchange medium in the condenser 222, thereby being heated. The heated first heat exchange medium returns to the battery pack 12, transferring heat to the battery pack 12, thus heating the battery pack 12. The evaporation path 215 and the air-cooling path 216 of the first water-side heat exchange component 211a are connected, as are the evaporation path 215 and the air-cooling path 216 of the second water-side heat exchange component 211b. The first heat exchange medium circulates between the evaporation path 215 and the air-cooling path 216, without passing through the battery pack 12. As the first heat exchange medium flows through the evaporation path 215, it exchanges heat with the second heat exchange medium in the evaporator 223, transferring heat to the second heat exchange medium. The cooled first heat exchange medium then flows through the air-cooling path 216, absorbing heat from the external environment at the air cooler 217. After its temperature rises, it re-enters the evaporation path 215, and the cycle repeats. This path provides a heat source for the evaporator 223 of the refrigerant-side heat exchange module 22, ensuring that the evaporator 223 can continuously absorb low-grade heat energy from the external environment, thus maintaining the heat pump cycle.

[0081] Furthermore, in heating mode, the compressor 221 of the first refrigerant-side heat exchange module 22a and / or the compressor 221 of the second refrigerant-side heat exchange module 22b are turned on. The compressor 221 drives the second heat exchange medium to circulate, causing the second heat exchange medium in the evaporator 223 to absorb heat from the first heat exchange medium, and release this heat, along with the heat converted from compression work, through the condenser 222 into the first heat exchange medium flowing through the condensation flow path 214, and then this part of the first heat exchange medium transfers the heat to the battery pack 12.

[0082] Furthermore, depending on the different temperature ranges of the ambient temperature, the operation of the two sets of refrigerant-side heat exchange modules 22 can be selectively controlled. Specifically, for example... Figure 11 As shown, when the ambient temperature is in the third temperature range, the compressor 221 of the first refrigerant-side heat exchange module 22a and the compressor 221 of the second refrigerant-side heat exchange module 22b control the second heat exchange medium to heat the first heat exchange medium. Figure 12 and Figure 13 As shown, when the ambient temperature is in the fourth temperature range, the compressor 221 of the first refrigerant-side heat exchange module 22a and the compressor 221 of the second refrigerant-side heat exchange module 22b alternately control the second heat exchange medium to heat the first heat exchange medium. The temperature in the third temperature range is higher than the temperature in the fourth temperature range.

[0083] When the ambient temperature is in the third temperature range, such as between 0°C and 10°C, the external environment still contains a relatively sufficient amount of extractable heat, making it relatively easy for the evaporator 223 to absorb heat from the environment. Figure 11 As shown, at this time, the compressor 221 of the first refrigerant-side heat exchange module 22a and the compressor 221 of the second refrigerant-side heat exchange module 22b start running simultaneously. The two sets of refrigerant-side heat exchange modules 22 work at the same time, jointly providing heat to the battery pack 12. The two sets of condensers 222 exchange heat with the first heat exchange medium at the same time, so that the first heat exchange medium flowing through the battery pack 12 obtains a large temperature rise, realizing rapid heating of the battery pack 12.

[0084] When the ambient temperature is in the fourth temperature range, such as below 0°C, the lower ambient temperature makes it more difficult for the evaporator 223 to absorb heat from the environment, and frost is more likely to form on the surface of the air cooler 217. In this case, the compressor 221 of the first refrigerant-side heat exchange module 22a and the compressor 221 of the second refrigerant-side heat exchange module 22b alternately control the second heat exchange medium to heat the first heat exchange medium. Specifically, as... Figure 12As shown, during a certain period, the compressor 221 of the first refrigerant-side heat exchange module 22a is turned on, while the compressor 221 of the second refrigerant-side heat exchange module 22b is turned off. Heat is provided by the first refrigerant-side heat exchange module 22a. At this time, the first heat exchange medium circulates between the evaporation path 215 and the air-cooling path 216 of the first water-side heat exchange component 211a, while the first heat exchange medium stops flowing between the evaporation path 215 and the air-cooling path 216 of the second water-side heat exchange component 211b. Figure 13 As shown, during another period, the compressor 221 of the first refrigerant-side heat exchange module 22a is turned off, and the compressor 221 of the second refrigerant-side heat exchange module 22b is started. Heat is provided by the second refrigerant-side heat exchange module 22b. At this time, the first heat exchange medium between the evaporation flow path 215 and the air-cooling flow path 216 of the second water-side heat exchange component 211b circulates, while the first heat exchange medium between the evaporation flow path 215 and the air-cooling flow path 216 of the first water-side heat exchange component 211a stops flowing.

[0085] In this embodiment, the temperature in the third temperature range is higher than that in the fourth temperature range. The third temperature range is a relatively high temperature environment (e.g., 0°C to 10°C). When the ambient temperature is in the third temperature range, the air cooler 217 is less prone to frost formation, and the compressors 221 of the first refrigerant-side heat exchange module 22a and the second refrigerant-side heat exchange module 22b can be controlled to heat simultaneously to achieve rapid heating. The fourth temperature range is a relatively low temperature environment (e.g., below 0°C). When the ambient temperature is in the fourth temperature range, the air cooler 217 is prone to frost formation. In view of this, the compressors 221 of the first refrigerant-side heat exchange module 22a and the second refrigerant-side heat exchange module 22b operate alternately. On the one hand, the operation of a single compressor 221 allows the refrigerant-side heat exchange module 22 to work continuously under relatively stable operating conditions, avoiding insufficient heat absorption by the evaporator 223 due to the simultaneous operation of both compressors 221, which would lead to increased frost formation. On the other hand, the alternating operation of the two sets of compressors 221 can avoid excessive wear caused by the long-term continuous operation of a single compressor 221, which is beneficial to extending the service life of the compressor 221. It is understandable that the alternating operation cycle of the compressor 221 of the first refrigerant-side heat exchange module 22a and the compressor 221 of the second refrigerant-side heat exchange module 22b can be set according to actual operating conditions, for example, switching every 30 minutes. During the switching process, the set of compressors 221 to be operated can be started first, and then the set of compressors 221 currently in operation can be shut down to ensure heating continuity. The temperature ranges of the third and fourth temperature zones can be adaptively adjusted according to the actual heating requirements of the energy storage device 10 and the performance of the refrigerant-side heat exchange modules 22.

[0086] In this embodiment, by connecting the battery pack 12 in series with two sets of condensing flow paths 214 in heating mode, and coordinating with the combined control of the compressors 221 of the two sets of refrigerant-side heat exchange modules 22, efficient heating of the battery pack 12 in low-temperature environments is achieved. Simultaneously, by selecting whether the two sets of compressors 221 operate simultaneously or alternately based on the ambient temperature range, the thermal management integrated module 20 can provide matching heating capacity under different low-temperature conditions. This enables rapid heating of the battery pack 12 when the ambient temperature is relatively high and frost is unlikely, while ensuring continuous heating and balancing the lifespan of the compressors 221 when the ambient temperature is low and frost is likely.

[0087] In one embodiment, such as Figure 14 and Figure 15 As shown, under low ambient temperature conditions, the air cooler 217, acting as the heat source for the evaporator 223, has a low surface temperature. Water vapor in the ambient air easily condenses and frosts as it flows through the air cooler 217. As the frost layer thickens, the airflow resistance of the air cooler 217 increases, reducing its heat exchange capacity with the ambient environment. This results in insufficient heat absorption by the evaporator 223, a decrease in the suction pressure of the compressor 221, and a reduction in its heating capacity. Therefore, when the frosting on the air cooler 217 reaches a certain level, a defrosting operation is required.

[0088] In view of this, the thermal management integrated module 20 of this embodiment has a defrosting mode. In the defrosting mode, the air cooler 217 of the first water-side heat exchange component 211a and the condenser 222 of the second refrigerant-side heat exchange module 22b are connected in series. The compressor 221 of the second refrigerant-side heat exchange module 22b controls the second heat exchange medium to heat the first heat exchange medium, so as to heat the air cooler 217 of the first water-side heat exchange component 211a; or, the air cooler 217 of the second water-side heat exchange component 211b and the condenser 222 of the first refrigerant-side heat exchange module 22a are connected in series. The compressor 221 of the first refrigerant-side heat exchange module 22a controls the second heat exchange medium to heat the first heat exchange medium, so as to heat the air cooler 217 of the second water-side heat exchange component 211b.

[0089] Specifically, such as Figure 14As shown, for the defrosting condition of the air cooler 217 of the first water-side heat exchange component 211a, the air cooler 217 of the first water-side heat exchange component 211a and the condenser 222 of the second refrigerant-side heat exchange module 22b are connected in series. The air cooling flow path 216 of the first water-side heat exchange component 211a, the condensation flow path 214 of the first water-side heat exchange component 211a, the condensation flow path 214 of the second water-side heat exchange component 211b, and the evaporation flow path 215 of the first water-side heat exchange component 211a are connected in series in sequence. After flowing out of the air cooler 217 of the first water-side heat exchange assembly 211a, the first heat exchange medium flows through the condensation path 214 of the second water-side heat exchange assembly 211b, where it exchanges heat with the condenser 222 of the second refrigerant-side heat exchange module 22b, absorbing the heat released by the second heat exchange medium in the condenser 222. The heated first heat exchange medium then returns to the air cooler 217 of the first water-side heat exchange assembly 211a, transferring heat to the air cooler 217 and melting the frost layer on its surface. During this defrosting process, the compressor 221 of the second refrigerant-side heat exchange module 22b starts running, driving the second heat exchange medium to circulate and release heat through its condenser 222. The compressor 221 of the first refrigerant-side heat exchange module 22a is in a stopped state. The first heat exchange medium circulates between the evaporation flow path 215 and the air-cooling flow path 216 of the second water-side heat exchange component 211b, providing a heat source for the evaporator 223 of the second refrigerant-side heat exchange module 22b, ensuring that the evaporator 223 can continuously absorb low-grade heat energy from the external environment, so that the heat pump cycle can be maintained.

[0090] like Figure 15As shown, for the defrosting condition of the air cooler 217 of the second water-side heat exchange component 211b, the air cooler 217 of the second water-side heat exchange component 211b is connected in series with the condenser 222 of the first refrigerant-side heat exchange module 22a. The air cooling flow path 216 of the second water-side heat exchange component 211b, the condensation flow path 214 of the second water-side heat exchange component 211b, the condensation flow path 214 of the first water-side heat exchange component 211a, and the evaporation flow path 215 of the second water-side heat exchange component 211b are connected in series in sequence. After the first heat exchange medium flows out of the air cooler 217 of the second water-side heat exchange assembly 211b, it flows through the condensation path 214 of the first water-side heat exchange assembly 211a and exchanges heat with the condenser 222 of the first refrigerant-side heat exchange module 22a. It absorbs the heat released by the second heat exchange medium in the condenser 222. The heated first heat exchange medium then returns to the air cooler 217 of the second water-side heat exchange assembly 211b, transferring heat to the air cooler 217 and melting the frost layer on its surface. During this defrosting process, the compressor 221 of the first refrigerant-side heat exchange module 22a starts running, driving the second heat exchange medium to circulate and release heat through its condenser 222. The compressor 221 of the second refrigerant-side heat exchange module 22b is in a stopped state. The first heat exchange medium circulates between the evaporation flow path 215 and the air-cooling flow path 216 of the first water-side heat exchange component 211a, providing a heat source for the evaporator 223 of the first refrigerant-side heat exchange module 22a, ensuring that the evaporator 223 can continuously absorb low-grade heat energy from the external environment, so that the heat pump cycle can be maintained.

[0091] In this embodiment, by connecting the condenser 222 of the refrigerant-side heat exchange module 22 in series with the air cooler 217 of the water-side heat exchange component 211, the heat released by the condenser 222 is used to heat and defrost the frosted air cooler 217, achieving a defrosting function without relying on external electric heating. This method utilizes the heat released by the condenser 222 during the operation of the compressor 221 as the defrosting heat source. The heat comes from the heat pump cycle itself, eliminating the need for additional electric heating elements. This simplifies the thermal management integrated module 20, reduces manufacturing costs, and improves the overall energy efficiency of the thermal management integrated module 20 under low-temperature conditions.

[0092] It should be noted that, since the defrosting temperature of the air cooler 217 is lower than the normal operating temperature of the battery pack 12, the battery pack 12 is not connected to the thermal management integrated module 20 in defrosting mode. That is, the first heat exchange medium does not flow through the battery pack 12 to avoid affecting its normal operation. The energy storage converter 11 can choose whether to connect to the thermal management integrated module 20 according to actual needs. Figure 14 An exemplary demonstration shows that during the defrosting operation of the air cooler 217 of the first water-side heat exchange component 211a, the energy storage converter 11 is not connected to the thermal management integration module 20, which can reduce the risk of condensation on the energy storage converter 11. Figure 15 An exemplary demonstration shows that during the defrosting operation of the air cooler 217 of the second water-side heat exchange component 211b, the energy storage converter 11 is connected to the thermal management integrated module 20. Specifically, the energy storage converter 11 is connected to the condensation flow path 214 of the first water-side heat exchange component 211a and the condensation flow path 214 of the second water-side heat exchange component 211b.

[0093] In summary, the thermal management integrated module of this application embodiment further includes at least two sets of refrigerant-side heat exchange modules, which are respectively connected to opposite sides of the water-side heat exchange module. Each set of refrigerant-side heat exchange modules includes a refrigerant flow channel plate and a compressor, condenser, and evaporator disposed on the refrigerant flow channel plate. The compressor is connected to the condenser and evaporator respectively through the flow channels in the refrigerant flow channel plate, and the condenser and evaporator are also connected to the water-side heat exchange module respectively through the refrigerant flow channel plate. In other words, by reasonably setting the arrangement position of the above-mentioned at least two sets of refrigerant-side heat exchange modules relative to the water-side heat exchange module, and coordinating the connection methods of the compressor, condenser, and evaporator in each set of refrigerant-side heat exchange modules, as well as the connection methods between the refrigerant-side heat exchange module and the water-side heat exchange module, this application embodiment is beneficial to simplifying the piping structure of the thermal management integrated module, thereby reducing the overall volume of the thermal management integrated module, shortening the R&D cycle of energy storage equipment and reducing R&D costs, and also reducing maintenance difficulty and costs.

[0094] The thermal management integrated module of this application embodiment, through its pipeline-free integrated design, simplifies the pipeline structure, reduces the module size, and lowers the risk of joint leakage, thereby improving space utilization, ease of operation and maintenance, and system reliability.
