Technical Field

[0001] This utility model relates to the field of thermal management technology, and in particular to a water-cooled energy storage cabinet, an energy storage cabinet thermal management system, and an energy storage cabinet. Background Technology

[0002] The thermal management system for energy storage cabinets currently faces several technical challenges and problems, which limit the performance and reliability of these cabinets. A power conversion system (PCS) is a type of power electronic device. Its main function in energy storage cabinets is to convert voltage and frequency during the storage and use of electrical energy, ensuring efficient utilization and a stable supply of power.

[0003] Many related technologies have shortcomings in the heat dissipation treatment of components such as batteries and power conversion modules inside the energy storage cabinet, making it difficult to meet the specific requirements of different components for the inlet liquid temperature, thus affecting the normal operation of the energy storage cabinet. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in related technologies. To this end, this utility model proposes an energy storage cabinet water chiller, an energy storage cabinet thermal management system, an energy storage cabinet, a first multi-channel on / off adjustment module, a second multi-channel on / off adjustment module, a compressor refrigeration module, and a dry cooler that work together to ensure that the power conversion module, battery, or other components requiring heat dissipation inside the energy storage cabinet operate within an ideal temperature range, thereby improving the overall performance and reliability of the energy storage cabinet.

[0005] This utility model proposes a water-cooled energy storage cabinet, comprising:

[0006] The heat exchanger is equipped with a first heat exchange pipe and a second heat exchange pipe;

[0007] The first multi-channel on / off adjustment module includes a first port, a second port, a third port, and a fourth port;

[0009] A compressor refrigeration module includes a compressor and a condenser; wherein the compressor and the condenser are connected in series in the first heat exchange pipe;

[0010] A dry cooler is provided between the fourth port and the fifth port via a dry cooler refrigeration pipe;

[0011] The first cooling channel is located between the second port and the seventh port;

[0012] A second cooling channel is disposed between the first port and the seventh port; wherein the first cooling channel and the second cooling channel share a common cooling channel segment.

[0014] In this invention, the cooperation between the heat exchanger, the first multi-channel on / off regulating module, the second multi-channel on / off regulating module, the compressor refrigeration module, and the dry cooler is key to achieving thermal management. These components work together to ensure that the components within the energy storage cabinet receive suitable inlet liquid temperatures under various environmental conditions, meeting their specific requirements. The first multi-channel on / off regulating module, in conjunction with the second multi-channel on / off regulating module, initially regulates the temperature inside the energy storage cabinet by controlling the flow direction and flow rate of the heat exchange medium. It allows the heat exchange medium to be distributed among different heat exchange pipes, thereby cooling components requiring heat dissipation, such as the power conversion module and batteries inside the energy storage cabinet. This modular design provides flexibility, enabling the energy storage cabinet's water chiller to adjust its cooling strategy according to actual heat dissipation needs and environmental conditions. The compressor refrigeration module is responsible for providing cooling in high-temperature environments. The compressor refrigeration module effectively reduces the temperature of the heat exchange medium, allowing it to absorb more heat as it flows through various components within the energy storage cabinet, thus maintaining the compressor refrigeration module within a safe operating temperature range. In low-temperature environments, the dry cooler comes into play. It regulates the temperature of the heat exchange medium through heat exchange with the external environment, ensuring that the components inside the energy storage cabinet maintain a suitable inlet liquid temperature even without the compressor refrigeration module. The coordinated operation of these modules allows the energy storage cabinet water chiller to adapt to different ambient temperature changes and intelligently adjust its cooling strategy to meet the specific inlet liquid temperature requirements of the energy storage cabinet. Whether in the hot summer or the cold winter, this energy storage cabinet water chiller ensures that the power conversion modules, batteries, or other components requiring heat dissipation operate within an ideal temperature range, thereby improving the overall performance and reliability of the energy storage cabinet.

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0059] The thermal management system for energy storage cabinets currently faces several technical challenges and problems, which limit the performance and reliability of these cabinets. A power conversion system (PCS) is a type of power electronic device. Its main function in energy storage cabinets is to convert voltage and frequency during the storage and use of electrical energy, ensuring efficient utilization and a stable supply of power.

[0060] First, many related technologies have shortcomings in the heat dissipation treatment of components such as batteries and power conversion modules inside the energy storage cabinet, making it difficult to meet the specific requirements of different components for the inlet liquid temperature, thus affecting the normal operation of the energy storage cabinet.

[0061] Secondly, related technologies often overlook the importance of humidity control inside energy storage cabinets. Humidity control inside energy storage cabinets is also closely related to ambient temperature. A decrease in ambient temperature can lead to a greater temperature difference between the inside and outside of the energy storage cabinet, thereby increasing the risk of internal humidity and condensation. This can not only cause corrosion or short circuits in electronic components, but also affect the reliability and lifespan of the equipment.

[0062] Furthermore, the related technologies also present significant energy consumption issues in low-temperature environments. If the thermal management system of the energy storage cabinet still relies on compressors for cooling under low-temperature conditions, it will increase unnecessary energy consumption and reduce the system's energy efficiency. Therefore, the thermal management system needs to be able to intelligently adjust according to changes in ambient temperature to reduce energy consumption.

[0063] Furthermore, heating in extremely cold environments is another challenge for related technologies. In extremely cold environments, batteries and PCS may require additional heating to maintain normal operation. In this case, the thermal management system must consider not only cooling needs but also heating needs to ensure the performance and reliability of the equipment under harsh climatic conditions.

[0064] This utility model aims to solve at least one of the technical problems existing in related technologies. To this end, this utility model proposes a water-cooled energy storage cabinet, an energy storage cabinet thermal management system, and an energy storage cabinet, all of which can ensure that the power conversion module, battery, or other components requiring heat dissipation inside the energy storage cabinet operate within an ideal temperature range, thereby improving the overall performance and reliability of the energy storage cabinet.

[0065] The following explanation is based on the accompanying drawings.

[0066] Reference Figure 1 This utility model proposes a water-cooled energy storage cabinet 1000, which may include:

[0067] Heat exchanger 100 may include a first heat exchange pipe 110 and a second heat exchange pipe 120;

[0068] The first multi-channel on / off adjustment module 200 may include a first port 201, a second port 202, a third port 203 and a fourth port 204; wherein the third port 203 and the sixth port 302 are connected by a second heat exchange pipe 120.

[0069] The second multi-channel on / off adjustment module 300 may include a fifth port 301, a sixth port 302 and a seventh port 303;

[0070] The compressor refrigeration module 400 may include a compressor 410 and a condenser 420; wherein the compressor 410 and the condenser 420 are connected in series in the first heat exchange pipe 110;

[0071] Dry cooler 500 is installed between the fourth port 204 and the fifth port 301 via dry cooler refrigeration pipe 510;

[0072] The first cooling channel 600 is located between the second port 202 and the seventh port 303;

[0073] The second cooling channel 700 is located between the first port 201 and the seventh port 303; wherein the first cooling channel 600 and the second cooling channel 700 share a common cooling channel segment 310.

[0074] The energy storage cabinet water chiller 1000 proposed in this utility model provides an effective solution. Through the combined configuration of a heat exchanger 100, a first multi-channel on / off control module 200, a second multi-channel on / off control module 300, a compressor 410, a compressor refrigeration module 400, and a dry cooler 500, effective control of components such as the power conversion module and batteries inside the energy storage cabinet can be achieved. The energy storage cabinet water chiller 1000 mainly includes a heat exchanger 100, a first multi-channel on / off control module 200, a second multi-channel on / off control module 300, a compressor refrigeration module 400, and a dry cooler 500, as well as two refrigeration channels.

[0075] Specifically, in this invention, the cooperation between the heat exchanger 100, the first multi-channel on / off regulating module 200, the second multi-channel on / off regulating module 300, the compressor refrigeration module 400, and the dry cooler 500 is key to achieving thermal management. These components work together to ensure that the components within the energy storage cabinet receive suitable inlet liquid temperatures under various environmental conditions, meeting their specific requirements. The first multi-channel on / off regulating module 200, in conjunction with the second multi-channel on / off regulating module 300, performs initial temperature regulation inside the energy storage cabinet by controlling the flow direction and flow rate of the heat exchange medium. It allows the heat exchange medium to be distributed among different heat exchange pipes, thereby cooling components inside the energy storage cabinet such as the power conversion module and batteries that require heat dissipation. This modular design provides flexibility, enabling the energy storage cabinet chiller 1000 to adjust its cooling strategy according to actual heat dissipation needs and environmental conditions. The compressor refrigeration module 400 is responsible for providing cooling in high-temperature environments. The compressor refrigeration module 400 effectively reduces the temperature of the heat exchange medium, allowing it to absorb more heat as it flows through the various components within the energy storage cabinet, thus maintaining the compressor refrigeration module 400 within a safe operating temperature range. In low-temperature environments, the dry cooler 500 plays a crucial role, regulating the temperature of the heat exchange medium through heat exchange with the external environment. This ensures that even without the compressor refrigeration module 400, the components within the energy storage cabinet maintain a suitable inlet liquid temperature. The coordinated operation of these modules allows the energy storage cabinet water chiller 1000 to adapt to varying ambient temperatures, intelligently adjusting its cooling strategy to meet the specific inlet liquid temperature requirements of the energy storage cabinet. Whether in the hot summer or the cold winter, this energy storage cabinet water chiller 1000 ensures that the power conversion modules, batteries, or other components requiring heat dissipation operate within an ideal temperature range, thereby improving the overall performance and reliability of the energy storage cabinet.

[0076] It should be noted that the heat exchanger 100 is the core of the water-cooled unit 1000 of the energy storage cabinet, and consists of a first heat exchange pipe 110 and a second heat exchange pipe 120. The first heat exchange pipe 110 is responsible for connecting in series with the compressor 410 and condenser 420 in the compressor refrigeration module 400 to form a closed-loop heat exchange medium circulation, used to absorb and transfer the heat generated by the compressor 410 during operation. The second heat exchange pipe 120 is responsible for transferring this heat to the dry cooler 500, realizing the final release of thermal energy.

[0077] In this embodiment of the invention, the design of the first multi-channel on / off adjustment module 200 and the second multi-channel on / off adjustment module 300 provides a flexible fluid control path for the energy storage cabinet water chiller 1000. It is worth noting that, under the joint control of the first multi-channel on / off adjustment module 200 and the second multi-channel on / off adjustment module 300, the flow path of the heat exchange medium is adjusted, thereby ensuring that the temperature of various components requiring heat dissipation inside the energy storage cabinet is maintained at the required temperature. The first multi-channel on / off adjustment module 200 and the second multi-channel on / off adjustment module 300 can adjust the flow direction of the heat exchange medium to ensure that a suitable temperature is maintained inside the energy storage cabinet under both high and low temperature conditions.

[0078] The first multi-channel on / off control module 200, through the configuration of the first port 201, the second port 202, and the third port 203, allows adjustment of the path of the heat exchange medium flowing to the heat exchanger 100 or to the dry cooler 500 according to the heat dissipation requirements of the energy storage cabinet. The second multi-channel on / off control module 300 further provides control over the distribution and circulation of the heat exchange medium within the energy storage cabinet water chiller 1000. Through the configuration of the fifth port 301, the sixth port 302, and the seventh port 303, it realizes control over the flow direction of the heat exchange medium to meet different requirements (high temperature, low temperature, or other requirements), enabling the energy storage cabinet water chiller 1000 to achieve different cooling methods.

[0079] In this embodiment of the invention, the compressor refrigeration module 400 is the refrigeration core of the energy storage cabinet water chiller 1000, and may include a compressor 410 and a condenser 420. The compressor 410 is responsible for compressing the refrigerant, while the condenser 420 is responsible for cooling the compressed high-temperature and high-pressure heat exchange medium and releasing heat. The dry cooler 500 is located between the fourth port 204 and the fifth port 301 through the dry cooler refrigeration pipe 510, thereby achieving the cooling of the heat exchange medium. This design allows the energy storage cabinet water chiller 1000 to flexibly switch cooling modes under different ambient temperatures to adapt to different heat dissipation requirements.

[0080] It is worth noting that, under low-temperature conditions, the dry cooler 500 is connected to the first multi-channel on / off regulating module 200 and the second multi-channel on / off regulating module 300 via the dry cooler refrigeration pipe 510. This allows the heat exchange medium to be cooled by the dry cooler 500 at low temperatures, instead of relying on the compressor refrigeration module 400. In this way, even under low-temperature conditions, the components inside the energy storage cabinet can be maintained at a suitable temperature. Not using the compressor 410 for heat dissipation also saves some energy costs.

[0081] Furthermore, in this embodiment, the first multi-channel on / off adjustment module 200 and the second multi-channel on / off adjustment module 300 can flexibly control the connection of the dry cooler 500 and the compressor refrigeration module 400. This means that in some cases, the compressor refrigeration module 400 can be used specifically to dissipate heat from some components of the energy storage cabinet, while the dry cooler 500 can be used to dissipate heat from other components of the energy storage cabinet. In this way, the temperature of the energy storage cabinet components with different heat dissipation requirements can be flexibly adjusted to ensure that each component is maintained at a suitable temperature.

[0082] In this embodiment of the invention, the first cooling channel 600 is disposed between the second port 202 and the seventh port 303; the second cooling channel 700 is disposed between the first port 201 and the seventh port 303; wherein the first cooling channel 600 and the second cooling channel 700 share a common cooling channel section 310. The design of the first cooling channel 600 and the second cooling channel 700 provides different heat exchange paths for the energy storage cabinet water chiller 1000, allowing the heat exchange medium to carry out effective heat exchange inside the energy storage cabinet water chiller 1000, thereby ensuring that components requiring heat dissipation, such as the power conversion module and batteries, inside the energy storage cabinet can be appropriately cooled.

[0083] It should be noted that the first internal component 5000 and the second internal component 6000 are two different components within the energy storage cabinet that require heat dissipation. The first internal component 5000 can be a power conversion module, a battery, or other components requiring heat dissipation; similarly, the second internal component 6000 can also be a power conversion module, a battery, or other components requiring heat dissipation. The energy storage cabinet water chiller 1000 can be used to dissipate heat from various components within the energy storage cabinet that require heat dissipation. Since the energy storage cabinet water chiller 1000 has two cooling channels, a first cooling channel 600 and a second cooling channel 700, this embodiment of the application can use the first cooling channel 600 to dissipate heat from the first internal component 5000 and the second cooling channel 700 to dissipate heat from the second internal component 6000.

[0084] It is worth noting that the first cabinet internal component 5000 and the second cabinet internal component 6000 are components inside the energy storage cabinet. The first cabinet internal component 5000 and the second cabinet internal component 6000 can be set up corresponding to the energy storage cabinet water chiller 1000, but they are not components that the energy storage cabinet water chiller 1000 itself has.

[0085] Reference Figure 2In some embodiments provided by this utility model, the first multi-way on / off adjustment module 200 includes a first three-way valve 205 and a first three-way connector 206 connected in series in the second heat exchange pipe 120. The second port 202 and the third port 203 are led out from two ends of the first three-way valve 205, the first port 201 and the fourth port 204 are led out from two connectors of the first three-way connector 206, and the other end of the first three-way valve 205 is connected to the other connector of the first three-way connector 206.

[0086] The second multi-way on / off control module 300 is a second three-way valve 304, with the fifth port 301, the sixth port 302 and the seventh port 303 respectively led out from the three ends of the second three-way valve 304.

[0087] In some embodiments of this utility model, the first multi-way on / off regulating module 200 is designed using a combination of a first three-way valve 205 and a first three-way connector 206. This design allows for control of the flow direction of the heat exchange medium through different ports of the first three-way valve 205 and the first three-way connector 206, thereby achieving precise temperature regulation of components such as the power conversion module and batteries inside the energy storage cabinet. Specifically, the second port 202 and the third port 203 are led out from both ends of the first three-way valve 205, while the first port 201 and the fourth port 204 are led out from the two connectors of the first three-way connector 206. This means that the flow or cut-off of the heat exchange medium can be controlled through different ports of the first three-way valve 205 and the first three-way connector 206, providing the energy storage cabinet water chiller 1000 with temperature control capabilities under different operating modes on the second heat exchange pipe 120. In addition, the other end of the first three-way valve 205 is connected to the other end of the first three-way connector 206 to realize the series connection of the first three-way valve 205 and the first three-way connector 206 on the second heat exchange pipe 120.

[0088] In some embodiments of this invention, the second multi-way on / off regulating module 300 employs a second three-way valve 304, with the fifth port 301, sixth port 302, and seventh port 303 respectively leading out from the three ports of the second three-way valve 304. This design provides the system with more regulation options, allowing the heat exchange medium to be distributed across more paths. By controlling the second three-way valve 304, precise control of the heat exchange medium flow direction can be achieved, thereby providing a suitable temperature environment for the energy storage cabinet under different operating conditions. This design not only improves the energy efficiency of the energy storage cabinet's water chiller 1000 but also enhances its adaptability, enabling it to operate stably over a wider range of ambient temperatures.

[0089] It should be understood that the multi-channel on / off regulating module design of the 1000 water-cooled chiller in the energy storage cabinet, through flexible valve control, achieves precise regulation of the heat exchange medium flow direction, thereby providing the energy storage cabinet with efficient and reliable thermal management capabilities. This design enables the energy storage cabinet to maintain suitable temperatures for internal components under different environmental conditions by changing the flow direction and distribution of the heat exchange medium, ensuring the performance and reliability of internal components such as the power conversion module and batteries.

[0090] In this invention, the water-cooled unit 1000 for the energy storage cabinet can achieve efficient thermal management of components such as the power conversion module and batteries inside the energy storage cabinet. Specifically:

[0091] When the ambient temperature exceeds a first temperature threshold, it indicates that the ambient temperature inside the energy storage cabinet is relatively high. This embodiment of the application can perform a series of operations to cool the interior of the energy storage cabinet. Specifically, the first multi-channel on / off adjustment module 200 can connect to the first port 201, the second port 202, and the third port 203, while the second multi-channel on / off adjustment module 300 can also connect to the sixth port 302 and the seventh port 303. In this way, the heat exchange medium flows in the second heat exchange pipe 120, the first cooling channel 600, and the second cooling channel 700 to absorb and transfer heat. Simultaneously, the compressor cooling module 400 can activate the compressor 410, thereby enhancing the heat dissipation effect on various components inside the energy storage cabinet, such as the power conversion module and the battery. This intelligent temperature control strategy ensures that even in high-temperature environments, the temperature inside the energy storage cabinet can still be maintained within a suitable range.

[0092] When the ambient temperature drops below the second temperature threshold, it means that the ambient temperature of the energy storage cabinet is relatively low. In this embodiment, the system can switch to another mode to maintain the internal temperature of the energy storage cabinet. In this case, the first multi-channel on / off adjustment module 200 can connect the first port 201, the second port 202, and the fourth port 204, while the second multi-channel on / off adjustment module 300 can connect the fifth port 301 and the seventh port 303. In this situation, the dry cooler 500 is allowed to participate in cooling. To reduce unnecessary energy consumption and avoid overcooling, the compressor cooling module 400 can shut down the compressor 410. As a result, the heat exchange medium flows in the dry cooler cooling pipe 510, the first cooling channel 600, and the second cooling channel 700 to absorb and transfer heat. Even in low-temperature environments, the internal temperature of the energy storage cabinet can still be maintained, ensuring that the heat dissipation requirements of components such as the power conversion module and batteries inside the energy storage cabinet are met.

[0093] It should be understood that this intelligent control strategy based on changes in ambient temperature enables the energy storage cabinet's water-cooled chiller 1000 to maintain a suitable internal temperature under different environmental conditions by precisely controlling the flow path of the heat exchange medium and the operating status of the compressor 410. This thermal management method not only improves the performance and reliability of the energy storage cabinet but also optimizes energy efficiency, making it a thermal management solution suitable for various environmental conditions.

[0094] Reference Figure 3 In some embodiments provided by this utility model, the first multi-way on / off adjustment module 200 is a four-way valve, with the first port 201, the second port 202, the third port 203 and the fourth port 204 respectively led out from the four ends of the four-way valve;

[0095] The second multi-way switching adjustment module 300 is a second three-way connector 305, with the fifth port 301, the sixth port 302 and the seventh port 303 respectively led out from the three connectors of the second three-way connector 305.

[0096] In some embodiments of this invention, the first multi-way on / off regulating module 200 employs a four-way valve design, which significantly improves the temperature regulation capability and flexibility of the energy storage cabinet water chiller 1000. The four-way valve allows the heat exchange medium to be distributed and circulated in four directions. Specifically, the first port 201, the second port 202, the third port 203, and the fourth port 204 are respectively led out from the four ports of the four-way valve. The second multi-way on / off regulating module 300 employs a second three-way connector 305 design, where the fifth port 301, the sixth port 302, and the seventh port 303 are respectively led out from the three ports of the second three-way connector 305. This configuration allows for more complex flow paths of the heat exchange medium within the energy storage cabinet, thereby enabling more precise control of the cooling effect.

[0097] By utilizing the four-way valve and the second / third-way connector 305, the flow direction of the heat exchange medium can be dynamically adjusted based on data from the temperature sensors inside the energy storage cabinet, thereby achieving more precise temperature control. For example, when the ambient temperature is high, the four-way valve can direct more of the heat exchange medium to areas with higher heat dissipation requirements, such as the power conversion module; while when the ambient temperature is low, the flow of the heat exchange medium can be reduced to avoid overcooling.

[0098] In summary, by combining the four-way valve and the three-way connector, the embodiment of this invention provides an efficient and reliable structure for the thermal management solution of the energy storage cabinet. This design not only improves the energy efficiency of the energy storage cabinet's water chiller 1000, but also enhances its adaptability, enabling it to operate stably over a wider range of ambient temperatures, thus ensuring the performance and reliability of internal components such as the power conversion module and batteries.

[0099] Reference Figure 4 In some embodiments provided by this utility model, the compressor refrigeration module 400 further includes a dehumidification evaporation unit 430, which is disposed in the dehumidification evaporation pipe 440. The dehumidification evaporation pipe 440 connects the first heat exchange pipe 110 to the opposite ends of the heat exchanger 100 on the primary side.

[0100] In some embodiments of this utility model, the energy storage cabinet water chiller 1000 may further include a dehumidification evaporation unit 430. This design is mainly used to further enhance the dehumidification capacity of the energy storage cabinet water chiller 1000. The dehumidification evaporation unit 430 is disposed in a dehumidification evaporation pipe 440, which connects the opposite ends of the primary side of the heat exchanger 100. This arrangement means that the dehumidification evaporation unit 430 is integrated into the circulation of the first heat exchange pipe 110, so that the heat exchange medium flowing through the primary side can absorb moisture when passing through the dehumidification evaporation unit 430, thereby achieving the dehumidification function.

[0101] In some embodiments, the dehumidification evaporation pipe 440 is connected in parallel with the compressor refrigeration pipe 450, which may be a pipe used to connect the compressor 410 and the condenser 420 in series. This configuration allows the energy storage cabinet chiller 1000 to perform refrigeration and dehumidification operations simultaneously when needed. When the energy storage cabinet chiller 1000 detects excessively high humidity inside the energy storage cabinet, the dehumidification evaporation unit 430 can be activated to reduce the humidity of the energy storage cabinet through the circulation of the heat exchange medium. The advantage of this design is that it provides dehumidification functionality. Some components inside the energy storage cabinet are very sensitive to humidity; if the energy storage cabinet is placed in a relatively high humidity environment, excessive humidity may lead to performance degradation or even damage to the equipment. By integrating dehumidification functionality, the energy storage cabinet chiller 1000 can more comprehensively control the internal environment, ensuring that the equipment operates under ideal conditions.

[0102] It should be understood that by integrating a dehumidification and evaporation unit 430 into the energy storage cabinet's water chiller 1000, this invention provides a solution that can effectively control both temperature and humidity. This design enables the energy storage cabinet to operate stably under a wider range of environmental conditions, while protecting the internal equipment from the effects of high temperature and high humidity.

[0103] In some more specific embodiments, the convergence point of the compressor refrigeration pipe 450, the dehumidification evaporation pipe 440 and the first heat exchange pipe 110 is a pipe confluence node 460. A first electronic expansion valve 461 is provided on the first heat exchange pipe 110 between the heat exchanger 100 and the pipe confluence node 460, and a second electronic expansion valve 462 is provided on the dehumidification evaporation pipe 440 between the dehumidification evaporation unit 430 and the pipe confluence node 460.

[0104] It should be noted that the primary function of the first electronic expansion valve 461 and the second electronic expansion valve 462 is to control the flow rate of the refrigerant. First electronic expansion valve 461: The first electronic expansion valve 461 is used to control the flow rate of the refrigerant entering the first heat exchange pipe 110. By adjusting the opening degree of the first electronic expansion valve 461, the flow rate of the refrigerant can be precisely controlled, thereby precisely controlling the heat exchange capacity of the heat exchanger 100. In high-temperature environments, the first electronic expansion valve 461 can be fully or partially open to allow more refrigerant to flow through the heat exchanger 100. In low-temperature environments, the flow rate may be reduced to reduce the cooling effect. It should be understood that in different operating modes, the opening degree of the first electronic expansion valve 461 in this embodiment will be adjusted according to requirements to adapt to different thermal management strategies. Second electronic expansion valve 462: The second electronic expansion valve 462 is located on the path of the refrigerant flow in the dehumidification evaporation pipe 440 and is used to control the flow rate of the refrigerant flowing to the dehumidification evaporation unit 430.

[0105] Reference Figure 5 In some embodiments provided by this utility model, the energy storage cabinet water chiller 1000 also includes a heater 800, which is disposed in the second heat exchange pipe 120.

[0106] In some embodiments of this invention, the energy storage cabinet water chiller 1000 is designed to meet the requirements of extreme low-temperature environments, and a heater 800 component is specifically added and integrated into the second heat exchange pipe 120. The main purpose of this design is to ensure that the temperature inside the energy storage cabinet can be maintained within an ideal operating range under low-temperature conditions, thereby ensuring the normal operation of the battery, power conversion module, or other temperature-sensitive components.

[0107] It should be noted that the heater 800 allows the energy storage cabinet chiller 1000 to actively input heat into the heat exchange medium in the second heat exchange pipe 120 when the external ambient temperature is low. This ensures that even in cold climates, the heat exchange medium provides sufficient heat to maintain the required temperature of the internal equipment as it flows through the energy storage cabinet. By integrating the heater 800 into the second heat exchange pipe 120, the energy storage cabinet chiller 1000 can implement a more flexible temperature control strategy. For example, when the temperature of components such as the power conversion module and batteries inside the energy storage cabinet is detected to drop below a set threshold, the thermal management control module can automatically activate the heater 800 to raise the temperature of the batteries, power conversion module, or other components inside the energy storage cabinet by heating the heat exchange medium in the second heat exchange pipe 120. This intelligent temperature regulation mechanism not only improves the adaptability of the energy storage cabinet but also helps to improve the energy efficiency and reliability of the energy storage cabinet chiller 1000.

[0108] Furthermore, the addition of heater 800 enables the energy storage cabinet water chiller 1000 to cope with more complex climatic conditions, ensuring a stable internal environment for the energy storage cabinet regardless of whether it is a hot summer or a cold winter. This design is particularly suitable for energy storage cabinets installed outdoors or in areas with variable climates, enhancing the practicality and flexibility of the energy storage cabinet water chiller 1000.

[0109] It should be understood that by adding a heater 800 to the water-cooled chiller 1000 of the energy storage cabinet and placing it in the second heat exchange pipe 120, this invention provides a comprehensive thermal management solution capable of both cooling and heating. This design enables the energy storage cabinet to maintain optimal performance under various environmental conditions while ensuring the safe and stable operation of the internal electronic equipment.

[0110] According to some specific embodiments of this application, when the ambient temperature drops below the third temperature threshold, it means that the ambient temperature of the energy storage cabinet is already very low. Embodiments of this application can take more proactive measures to heat the interior of the energy storage cabinet. At this time, the first multi-channel on / off adjustment module 200 can connect all its ports, that is, the first port 201, the second port 202, the third port 203, and the fourth port 204 can all be connected. Additionally, the second multi-channel on / off adjustment module 300 can connect the fifth port 301, the sixth port 302, and the seventh port 303. The compressor 410 can be turned off to avoid overcooling. Simultaneously, the heater 800 is activated, thereby inputting heat into the heat exchange medium and increasing the temperature inside the energy storage cabinet. In this way, the heat exchange medium flows in the second heat exchange pipe 120, the dry cooler refrigeration pipe 510, the first refrigeration channel 600, and the second refrigeration channel 700. This heating mechanism is crucial for protecting the internal equipment of the energy storage cabinet under extreme low-temperature conditions, ensuring that even in very cold environments, components such as the power conversion module and batteries inside the energy storage cabinet can maintain ideal operating temperatures.

[0111] Reference Figure 6 In some embodiments provided by this utility model, the first refrigeration channel 600 and the second refrigeration channel 700 are connected to the seventh port 303 via a common refrigeration channel section 310, and the refrigeration channel section 310 is provided with an expansion tank 311.

[0112] In some embodiments of this utility model, the design of the energy storage cabinet water chiller 1000 further optimizes the flow and temperature control mechanism of the heat exchange medium by setting up a first refrigeration channel 600 and a second refrigeration channel 700, and connecting them to the seventh port 303 through a common refrigeration channel section 310. This design not only improves the efficiency of heat exchange but also increases the flexibility and reliability of the energy storage cabinet water chiller 1000. The common refrigeration channel section 310 is the confluence point of the first refrigeration channel 600 and the second refrigeration channel 700, allowing heat exchange media from different heat exchange paths to mix and return to the second multi-channel on / off regulating module 300. A key component of this design is the expansion tank 311, which is located in the refrigeration channel section 310. The main function of the expansion tank 311 is to regulate the volume change of the heat exchange medium, as the heat exchange medium expands or contracts due to temperature changes during circulation.

[0113] When the heat exchange medium is heated, it expands, and when it cools, it contracts. The expansion tank 311 provides additional space to accommodate the increased volume of the heat exchange medium due to temperature rise, thereby preventing excessive pressure rise in the energy storage cabinet chiller 1000 and helping to protect pipes and components from damage caused by excessive pressure. At the same time, when the heat exchange medium cools and contracts, the heat exchange medium in the expansion tank 311 can return to the refrigeration passage section 310, maintaining an adequate supply of heat exchange medium within the energy storage cabinet chiller 1000.

[0114] In addition, the expansion tank 311 also serves to stabilize pressure and release gas. It ensures stable pressure inside the energy storage cabinet chiller 1000 and releases any gases that may accumulate within it, preventing gas blockages that could affect the flow of the heat exchange medium and heat exchange efficiency. By integrating the expansion tank 311 into the cooling channel section 310, the requirements for stable heat exchange medium volume and pressure buffering within the energy storage cabinet chiller 1000 are met. This design not only improves the thermal management capabilities of the energy storage cabinet chiller 1000 but also enhances its safety and stability. This configuration allows the energy storage cabinet chiller 1000 to respond more effectively to temperature changes while reducing pressure fluctuations caused by changes in heat exchange medium volume, ensuring appropriate temperature control for the internal equipment under various environmental conditions.

[0115] It should be understood that by setting an expansion tank 311 in the refrigeration channel section 310 and connecting it to the first refrigeration channel 600 and the second refrigeration channel 700, this utility model provides an efficient and reliable thermal management solution, enabling the energy storage cabinet water chiller 1000 to better adapt to different working conditions and improving the efficiency and lifespan of the entire energy storage cabinet water chiller 1000.

[0116] Reference Figure 7 This utility model also proposes an energy storage cabinet thermal management system, which is used for thermal management of energy storage cabinets and may include:

[0117] The above-mentioned energy storage cabinet water chiller 1000;

[0118] Environmental sensor 2000 is used to detect environmental sensing parameters of the target environment corresponding to the energy storage cabinet;

[0119] The cabinet-in-slot sensor 3000 is used to detect the corresponding internal sensing parameters of the energy storage cabinet.

[0120] The thermal management control module 4000 is used to control the water chiller 1000 of the energy storage cabinet based on environmental sensor parameters and cabinet sensor parameters.

[0121] The energy storage cabinet thermal management system proposed in this utility model aims to provide precise thermal management for energy storage cabinets. This energy storage cabinet thermal management system not only includes the energy storage cabinet water chiller 1000 mentioned in the above embodiments, but also integrates environmental sensors 2000, cabinet-in-cabinet sensors 3000, and thermal management control module 4000, forming a closed-loop control energy storage cabinet thermal management system.

[0122] The water-cooled chiller 1000, as the core component of the energy storage cabinet's thermal management system, is responsible for regulating the internal temperature of the energy storage cabinet through heat exchange medium circulation. The cooperation between the heat exchanger 100, the first multi-channel on / off regulating module 200, the second multi-channel on / off regulating module 300, the compressor refrigeration module 400, and the dry cooler 500 is crucial for achieving thermal management. These components work together to ensure that the parts within the energy storage cabinet receive suitable inlet liquid temperatures under various environmental conditions, meeting their specific requirements.

[0123] It should be noted that the environmental sensor 2000 and the cabinet-internal sensor 3000 are responsible for monitoring parameters of the external environment and internal status of the energy storage cabinet, such as temperature and humidity. The data collected by these sensors is crucial for the thermal management control module 4000, as it provides real-time environmental and cabinet-internal status information. The environmental sensor 2000 can detect external climatic conditions, such as changes in temperature and humidity, while the cabinet-internal sensor 3000 can monitor changes in temperature, humidity, and potential heat dissipation requirements inside the energy storage cabinet. Specifically:

[0124] The environmental sensor 2000 is responsible for monitoring the external environmental conditions of the energy storage cabinet, capturing changes in key parameters such as temperature and humidity to obtain environmental sensing parameters. This means that, whether in the hot summer or the cold winter, the environmental sensor 2000 can track fluctuations in the external climate in real time, providing necessary data support for the thermal management control module 4000. This data helps the system understand the potential impact of the external environment on the energy storage cabinet, thereby taking appropriate measures to maintain the stability of the internal environment.

[0125] The 3000 in-cabinet sensor focuses on the internal state of the energy storage cabinet, reflecting this state in the in-cabinet sensing parameters. These parameters accurately detect temperature and humidity levels within the cabinet, as well as any changes in heat dissipation requirements that might affect equipment performance, ensuring that components such as the power conversion modules and batteries operate under the necessary conditions. By monitoring these in-cabinet sensing parameters in real time, the 3000 in-cabinet sensor can promptly identify any anomalies that could lead to performance degradation or equipment damage and take appropriate corrective measures.

[0126] The thermal management control module 4000 of this utility model is the brain of the energy storage cabinet's thermal management system. It analyzes and makes decisions based on data provided by the environmental sensor 2000 and the cabinet's internal sensor 3000, and then controls the various components of the energy storage cabinet's water chiller 1000. For example, the thermal management control module 4000 can control the internal environment of the energy storage cabinet by adjusting the operating speed of the compressor 410, switching the flow direction of the multi-channel on / off regulating module, controlling the operating status of the dry cooler 500 and the heater 800, or adjusting the operation of the dehumidification evaporation unit 430.

[0127] It should be noted that the thermal management system for energy storage cabinets can significantly improve the performance and reliability of energy storage cabinets. Through real-time monitoring and automatic adjustment, the thermal management system can adapt to constantly changing environmental conditions, maintaining the temperature and humidity inside the energy storage cabinet within an ideal range, thereby extending the service life of electronic equipment and power conversion modules and ensuring their efficient operation.

[0128] It should be understood that the automated control of the thermal management control module 4000 reduces the need for manual intervention, lowers maintenance costs, and improves the stability of the energy storage cabinet thermal management system. Through intelligent management, the energy storage cabinet thermal management system can achieve higher energy efficiency and better operational performance, making it a reliable solution suitable for various environmental conditions.

[0129] In some embodiments provided by this utility model, the thermal management control module 4000 is configured as follows:

[0130] When the environmental sensing parameters indicate that the ambient temperature of the target environment is higher than the first temperature threshold, based on the environmental sensing parameters and the sensing parameters inside the cabinet, the first port 201, the second port 202 and the third port 203 of the first multi-way on / off adjustment module 200 are connected in the energy storage cabinet water chiller 1000, and the sixth port 302 and the seventh port 303 of the second multi-way on / off adjustment module 300 are connected. The compressor 410 of the energy storage cabinet water chiller 1000 is then turned on to achieve the desired temperature of the heat exchange medium in the first refrigeration channel 600 and the second refrigeration channel 700.

[0131] In some embodiments of this invention, the thermal management control module 4000 is designed to intelligently adjust the operating status of the energy storage cabinet's water chiller 1000 based on real-time temperature data from the environment and inside the cabinet. Specifically, when the environmental sensor 2000 detects that the ambient temperature of the target environment is higher than a set first temperature threshold, the thermal management control module 4000 will initiate a series of actions to cope with this high-temperature situation. The target environment is the environment in which the energy storage cabinet is located.

[0132] It should be noted that the thermal management control module 4000 first analyzes environmental and cabinet sensor parameters, then makes a decision to connect its first port 201, second port 202, and third port 203 by controlling the first multi-channel on / off adjustment module 200 in the energy storage cabinet water chiller 1000. This connection method allows the heat exchange medium to circulate through a specific path, exchanging heat in the most efficient way.

[0133] In this invention, the thermal management control module 4000, in conjunction with the energy storage cabinet water chiller 1000, enables efficient thermal management of components such as the power conversion module and batteries inside the energy storage cabinet. Specifically:

[0134] When the thermal management control module 4000 detects that the ambient temperature is higher than the first temperature threshold, it means that the ambient temperature of the energy storage cabinet is relatively high. In this embodiment, the energy storage cabinet water chiller 1000 can perform a series of operations to cool the inside of the energy storage cabinet. Specifically, the first multi-channel on / off adjustment module 200 can connect to the first port 201, the second port 202, and the third port 203, while the second multi-channel on / off adjustment module 300 can also connect to the sixth port 302 and the seventh port 303. In this way, the heat exchange medium flows in the second heat exchange pipe 120, the first cooling channel 600, and the second cooling channel 700 to absorb and transfer heat. Simultaneously, the compressor cooling module 400 can activate the compressor 410, thereby enhancing the heat dissipation effect on various components inside the energy storage cabinet, such as the power conversion module and the battery. This intelligent temperature control strategy ensures that the temperature inside the energy storage cabinet can still be maintained within a suitable range even in high-temperature environments.

[0135] When the thermal management control module 4000 detects that the ambient temperature has dropped below the second temperature threshold, it means that the ambient temperature of the energy storage cabinet is relatively low. In this embodiment, the water chiller 1000 of the energy storage cabinet can be switched to another mode to maintain the internal temperature of the energy storage cabinet. In this case, the first multi-way switching module 200 can connect the first port 201, the second port 202, and the fourth port 204, while the second multi-way switching module 300 can connect the fifth port 301 and the seventh port 303. In this case, the dry cooler 500 is allowed to participate in cooling. To reduce unnecessary energy consumption and avoid overcooling, the compressor cooling module 400 can shut down the compressor 410. In this way, the heat exchange medium flows in the dry cooler cooling pipe 510, the first cooling channel 600, and the second cooling channel 700 to absorb and transfer heat. The internal temperature of the energy storage cabinet can still be maintained in the low-temperature environment, ensuring that the heat dissipation requirements of components such as the power conversion module and batteries inside the energy storage cabinet are met.

[0136] When the thermal management control module 4000 detects that the ambient temperature has dropped below the third temperature threshold, it means that the ambient temperature of the energy storage cabinet is extremely low. At this time, in the water chiller 1000 of the energy storage cabinet, the first multi-channel on / off regulating module 200 can connect all its ports, namely, the first port 201, the second port 202, the third port 203, and the fourth port 204. In addition, the second multi-channel on / off regulating module 300 can connect the fifth port 301, the sixth port 302, and the seventh port 303. The compressor 410 can be turned off to avoid overcooling. At the same time, the control heater 800 is started, thereby inputting heat into the heat exchange medium and raising the temperature inside the energy storage cabinet. In this way, the heat exchange medium flows in the second heat exchange pipe 120, the dry cooler refrigeration pipe 510, the first refrigeration channel 600, and the second refrigeration channel 700. This heating mechanism is crucial for protecting the internal equipment of the energy storage cabinet under extreme low temperature conditions, ensuring that even in very cold environments, components such as the power conversion module and batteries inside the energy storage cabinet can maintain ideal operating temperatures.

[0137] It should be understood that this intelligent control strategy based on changes in ambient temperature, where the thermal management control module 4000 works in conjunction with the energy storage cabinet's water chiller 1000, can precisely control the flow path of the heat exchange medium and the operating status of the compressor 410 under different environmental conditions. This allows the heat exchange medium to circulate along a specific path and exchange heat in the most efficient way, thus maintaining a suitable temperature inside the energy storage cabinet. This thermal management method not only improves the performance and reliability of the energy storage cabinet but also optimizes energy efficiency, making it a thermal management solution for energy storage cabinets suitable for various environmental conditions.

[0138] In this way, the heat exchange medium can more effectively absorb and remove the heat generated inside the energy storage cabinet as it flows through the first cooling channel 600 and the second cooling channel 700. This not only helps maintain the temperature inside the cabinet within a suitable range, but also allows components such as the power conversion modules and batteries inside the energy storage cabinet to maintain ideal operating temperatures.

[0139] It should be understood that the thermal management control module 4000 provided by this utility model realizes the control of the water chiller 1000 of the energy storage cabinet through intelligent analysis and response to environmental changes. This control strategy not only improves the performance and reliability of the energy storage cabinet in high-temperature environments, but also optimizes the energy efficiency and stability of the entire energy storage cabinet thermal management system.

[0140] In some embodiments provided by this utility model, the thermal management control module 4000 is configured as follows:

[0141] When the ambient temperature of the target environment is lower than the second temperature threshold as indicated by the environmental sensing parameters, the first port 201, the second port 202, and the fourth port 204 of the first multi-channel on / off adjustment module 200 are connected in the energy storage cabinet water chiller 1000, and the fifth port 301 and the seventh port 303 of the second multi-channel on / off adjustment module 300 are connected. The compressor 410 of the energy storage cabinet water chiller 1000 is then turned off to adjust the temperature of the heat exchange medium in the first refrigeration channel 600 and the second refrigeration channel 700.

[0142] It should be noted that the thermal management control module 4000 analyzes real-time data from the environmental sensor 2000 and the cabinet sensor 3000, and then makes corresponding adjustments. In this case, the thermal management control module 4000 controls the first multi-channel on / off regulating module 200 in the energy storage cabinet's water chiller 1000, connecting only its first port 201 and second port 202. This configuration allows the heat exchange medium to circulate through a specific path, thereby achieving effective heat exchange in a low-temperature environment. In this mode, the role of the dry cooler 500 becomes particularly critical. Since the compressor 410 is shut down to reduce energy consumption and avoid unnecessary cooling, the dry cooler 500, as an auxiliary cooling device, utilizes ambient air to help maintain the temperature balance inside the energy storage cabinet. The dry cooler 500 is connected to the second heat exchange pipe 120 through its refrigeration pipe, allowing it to utilize the low temperature of the outside air to help lower or stabilize the temperature inside the energy storage cabinet without requiring the compressor 410. This cooling method is not only energy-efficient... In addition, the operating mode of the dry cooler 500 can be adjusted according to the environment and real-time data from the internal sensors 3000 to ensure that the temperature inside the energy storage cabinet is maintained within a suitable range without starting the compressor 410.

[0143] In low-temperature environments, compressor 410 can be shut down to reduce excessive cooling. Dry cooler 500, acting as an auxiliary cooling device, utilizes ambient air to help maintain the temperature balance of components such as the power conversion modules and batteries inside the energy storage cabinet. This helps prevent the temperature of these components from becoming too low, thus protecting them from the effects of low temperatures. Through intelligent control, dry cooler 500 works in conjunction with thermal management control module 4000 to adjust the cooling intensity according to actual needs, avoiding over-cooling and ensuring normal operation of the equipment under low-temperature conditions. By precisely controlling the flow path of the heat exchange medium, it allows the medium to circulate through a specific path for the most efficient heat exchange, maintaining a suitable temperature inside the energy storage cabinet.

[0144] It should be understood that the dry cooler 500 provides an energy-saving and reliable low-temperature environment cooling solution in the energy storage cabinet thermal management system of this utility model. By enabling control of components such as the power conversion module and batteries inside the energy storage cabinet under low-temperature conditions, it improves the energy efficiency and reliability of the entire energy storage cabinet thermal management system, ensuring the stable operation of the energy storage cabinet under various environmental conditions.

[0145] In some embodiments provided by this utility model, the energy storage cabinet water chiller 1000 includes a heater 800, which is disposed in the second heat exchange pipe 120 of the energy storage cabinet water chiller 1000.

[0146] The thermal management control module 4000 is configured as follows:

[0147] When the environmental sensing parameters indicate that the ambient temperature of the target environment is lower than the third temperature threshold, based on the environmental sensing parameters and the sensing parameters inside the cabinet, the first port 201, the second port 202, the third port 203 and the fourth port 204 of the first multi-way on / off adjustment module 200 are connected in the energy storage cabinet water chiller 1000, and the fifth port 301, the sixth port 302 and the seventh port 303 of the second multi-way on / off adjustment module 300 are connected. The compressor 410 of the energy storage cabinet water chiller 1000 is turned off, and the heater 800 is started to adjust the temperature of the heat exchange medium in the first refrigeration channel 600 and the second refrigeration channel 700.

[0148] In some embodiments of this invention, the design of the energy storage cabinet water chiller 1000 specifically considers the need for effective thermal management of the energy storage cabinet under extreme low-temperature conditions. To this end, the energy storage cabinet water chiller 1000 includes a heater 800 integrated into a second heat exchange pipe 120 to provide the necessary heat when the ambient temperature is below a specific threshold.

[0149] When the environmental sensor 2000 detects that the ambient temperature is below the third temperature threshold, the thermal management control module 4000 needs to ensure that the temperature inside the energy storage cabinet is maintained within a suitable range. It will control the first multi-channel on / off adjustment module 200 to connect its first port 201, second port 202, and third port 203. This configuration allows the heat exchange medium to circulate within the water chiller 1000 of the energy storage cabinet. Simultaneously, the thermal management control module 4000 will activate the heater 800 to transfer heat to the heat exchange medium in the second heat exchange pipe 120, thereby maintaining the temperature inside the energy storage cabinet.

[0150] In some embodiments provided by this utility model, the compressor refrigeration module 400 includes a dehumidification evaporation unit 430. In the compressor refrigeration module 400, the dehumidification evaporation unit 430 is disposed in the dehumidification evaporation pipe 440, and the dehumidification evaporation pipe 440 connects the first heat exchange pipe 110 to the opposite ends of the heat exchanger 100 on the primary side. The thermal management control module 4000 is configured as follows:

[0151] When the sensor parameters inside the cabinet indicate that the energy storage cabinet has entered the closed state, the dehumidification and evaporation unit 430 is activated in the water chiller 1000 of the energy storage cabinet to regulate the humidity inside the energy storage cabinet, based on the environmental sensor parameters and the sensor parameters inside the cabinet.

[0152] It should be noted that this utility model also provides an embodiment of the dehumidification function. In this configuration, the compressor refrigeration module 400 includes a dehumidification evaporation unit 430, which is disposed in the dehumidification evaporation pipe 440. The dehumidification evaporation pipe 440 connects to the first heat exchange pipe 110 from both ends of the primary side of the heat exchanger 100 and is connected in parallel with the compressor refrigeration pipe 450. The compressor refrigeration pipe 450 refers to a section of pipe that connects the compressor 410 and the condenser 420 in series. Therefore, in some embodiments, the dehumidification evaporation pipe 440, the first heat exchange pipe 110, and the compressor refrigeration pipe 450 can be connected in parallel.

[0153] In some embodiments, when the internal sensor 3000 detects that the energy storage cabinet has entered a closed state, the thermal management control module 4000 activates the dehumidification evaporation unit 430 to reduce the humidity inside the energy storage cabinet. This measure helps prevent moisture condensation in the enclosed space, protecting the internal equipment of the energy storage cabinet from potential damage in a humid environment. The energy storage cabinet water chiller 1000 of this invention can provide precise thermal management under different environmental conditions. Whether in low-temperature or high-humidity environments, the energy storage cabinet thermal management system can regulate the temperature and humidity inside the energy storage cabinet by intelligently controlling the operation of the heater 800, the dehumidification evaporation unit 430, the multi-channel on / off adjustment module, and the compressor 410, ensuring that the power conversion module and other temperature-sensitive components always operate under ideal environmental conditions. This comprehensive thermal management approach improves the performance and reliability of the energy storage cabinet while optimizing energy efficiency.

[0157] The second cabinet internal component 6000 is located in the second refrigeration channel 700 of the energy storage cabinet water chiller 1000 in the energy storage cabinet thermal management system.
