In low-temperature environments, the dry cooler can play a role.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] The thermal management system of energy storage cabinets currently faces a variety of technical challenges and problems, which limit the performance and reliability of energy storage cabinets. The power conversion system (PCS) is a power electronic device. The main function of the power conversion module in the energy storage cabinet is to convert voltage and frequency during the storage and use of electric energy to ensure the effective use and stable supply of electric energy.

[0060] First, many related technologies have deficiencies in the heat dissipation treatment methods for 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, affecting the normal operation of the energy storage cabinet.

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

[0062] In addition, the related technology also has a significant energy consumption problem in low temperature environments. Under low temperature conditions, if the thermal management system of the energy storage cabinet still relies on the compressor for refrigeration, it will increase unnecessary energy consumption and reduce the energy efficiency of the system. Therefore, the thermal management system needs to be able to intelligently adjust according to changes in ambient temperature to reduce energy consumption.

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

[0064] The present invention aims to solve at least one of the technical problems existing in the related art. To this end, the present invention proposes an energy storage cabinet water cooler, 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 that need heat dissipation inside the energy storage cabinet work within an ideal temperature range, thereby improving the overall performance and reliability of the energy storage cabinet.

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

[0066] Reference Figure 1 The present invention proposes an energy storage cabinet water cooler 1000, which may include:

[0067] The 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 regulating 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 regulating 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 arranged in series on the first heat exchange pipe 110;

[0071] A dry cooler 500 is disposed between the fourth port 204 and the fifth port 301 through a dry cooler refrigeration pipe 510;

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

[0073] The second refrigeration channel 700 is disposed between the first port 201 and the seventh port 303 ; wherein the first refrigeration channel 600 and the second refrigeration channel 700 have a common refrigeration channel section 310 .

[0074] The energy storage cabinet water chiller 1000 proposed in the present invention provides an effective solution, which can realize effective control of the power conversion module and battery and other components inside the energy storage cabinet through the combination configuration of the heat exchanger 100, the first multi-way on-off adjustment module 200, the second multi-way on-off adjustment module 300, the compressor 410, the compressor refrigeration module 400 and the dry cooler 500. The energy storage cabinet water chiller 1000 mainly includes the heat exchanger 100, the first multi-way on-off adjustment module 200, the second multi-way on-off adjustment module 300, the compressor refrigeration module 400 and the dry cooler 500, and two refrigeration channels.

[0075] Specifically, in the present invention, the cooperation between the heat exchanger 100, the first multi-way on-off adjustment module 200, the second multi-way on-off adjustment module 300, the compressor refrigeration module 400 and the dry cooler 500 is the key to achieving thermal management. These components work together to ensure that the components in the energy storage cabinet can obtain a suitable liquid inlet temperature under various environmental conditions to meet their specific requirements. The first multi-way on-off adjustment module 200 cooperates with the second multi-way on-off adjustment module 300 to preliminarily adjust 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 between different heat exchange pipes, thereby cooling the power conversion module and battery inside the energy storage cabinet that need heat dissipation. This modular design provides flexibility, allowing the energy storage cabinet water chiller 1000 to adjust the cooling strategy according to actual heat dissipation requirements and environmental conditions. The compressor refrigeration module 400 is responsible for providing cooling in a high temperature environment. The compressor refrigeration module 400 can effectively reduce the temperature of the heat exchange medium so that it can absorb more heat when flowing through various components in the energy storage cabinet, thereby maintaining the compressor refrigeration module 400 within a safe operating temperature range. In a low temperature environment, the dry cooler 500 can play a role. It adjusts the temperature of the heat exchange medium through heat exchange with the external environment to ensure that even without using the compressor refrigeration module 400, the components in the energy storage cabinet can maintain a suitable liquid inlet temperature. The mutual cooperation of the above modules enables the energy storage cabinet water cooler 1000 to adapt to different ambient temperature changes and intelligently adjust the cooling strategy to meet the specific requirements of the energy storage cabinet for the liquid inlet temperature. Whether in hot summer or cold winter, this energy storage cabinet water cooler 1000 can ensure that the power conversion module, battery or other components that need 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.

[0076] It should be noted that the heat exchanger 100 is the core of the energy storage cabinet water cooler 1000, and is composed of a first heat exchange pipe 110 and a second heat exchange pipe 120. The first heat exchange pipe 110 is responsible for being connected in series with the compressor 410 and the condenser 420 in the compressor refrigeration module 400 to form a closed-loop heat exchange medium circulation for absorbing and transferring the heat generated by the compressor 410. The second heat exchange pipe 120 is responsible for transferring the heat to the dry cooler 500 to achieve the final release of heat energy.

[0077] In the embodiment of the present invention, the design of the first multi-way on-off regulating module 200 and the second multi-way on-off regulating 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-way on-off regulating module 200 and the second multi-way on-off regulating module 300, the flow path of the heat exchange medium is adjusted, so that the temperature of various components that need heat dissipation inside the energy storage cabinet can be maintained at the required temperature. The first multi-way on-off regulating module 200 and the second multi-way on-off regulating module 300 can adjust the flow direction of the heat exchange medium to ensure that the appropriate temperature inside the energy storage cabinet can be maintained under high or low temperature conditions.

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

[0079] In the embodiment of the present 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, and the condenser 420 is responsible for cooling the compressed high-temperature and high-pressure heat exchange medium to release heat. The dry cooler 500 is arranged between the fourth port 204 and the fifth port 301 through the dry cooler refrigeration pipe 510 to achieve cooling of the heat exchange medium. This design allows the energy storage cabinet water chiller 1000 to flexibly switch cooling modes at 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-way on-off adjustment module 200 and the second multi-way on-off adjustment module 300 through the dry cooler refrigeration pipeline 510, so that the heat exchange medium can be cooled by the dry cooler 500 under low temperature conditions, instead of relying on the compressor refrigeration module 400. In this way, even under low temperature conditions, the various components inside the energy storage cabinet can be maintained at a suitable temperature. When the compressor 410 is not used for heat dissipation, some energy costs can also be saved.

[0081] In addition, in the embodiment of the present application, the first multi-way on-off regulating module 200 and the second multi-way on-off regulating module 300 can flexibly control the access 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 to dissipate heat specifically for some components of the energy storage cabinet, while the dry cooler 500 can be used to dissipate heat for other components of the energy storage cabinet. In this way, adaptive temperature adjustment can be flexibly performed for energy storage cabinet components with different heat dissipation requirements to ensure that each component is maintained at a suitable temperature.

[0082] In the embodiment of the present invention, the first refrigeration channel 600 is disposed between the second port 202 and the seventh port 303; the second refrigeration channel 700 is disposed between the first port 201 and the seventh port 303; wherein the first refrigeration channel 600 and the second refrigeration channel 700 have a common refrigeration channel section 310. The design of the first refrigeration channel 600 and the second refrigeration channel 700 provides different heat exchange paths for the energy storage cabinet water cooler 1000, allowing the heat exchange medium to perform effective heat exchange inside the energy storage cabinet water cooler 1000, thereby ensuring that the power conversion module and battery and other components in the energy storage cabinet that need heat dissipation can be properly cooled.

[0083] It should be noted that the first in-cabinet component 5000 and the second in-cabinet component 6000 are two different components in the energy storage cabinet that have heat dissipation requirements. Among them, the first in-cabinet component 5000 can be a power conversion module, a battery or other components that require heat dissipation; similarly, the second in-cabinet component 6000 can also be a power conversion module, a battery or other components that require heat dissipation. The energy storage cabinet water cooler 1000 can be used to dissipate heat for various components that require heat dissipation in the energy storage cabinet. Since the energy storage cabinet water cooler 1000 has two refrigeration channels, the first refrigeration channel 600 and the second refrigeration channel 700. Therefore, the embodiment of the present application can use the first refrigeration channel 600 to dissipate heat for the first in-cabinet component 5000, and use the second refrigeration channel 700 to dissipate heat for the second in-cabinet component 6000.

[0084] It is worth noting that the first internal component 5000 and the second internal component 6000 are components in the energy storage cabinet. The first internal component 5000 and the second internal component 6000 can be arranged corresponding to the energy storage cabinet water cooler 1000, but they are not components possessed by the energy storage cabinet water cooler 1000 itself.

[0085] Reference Figure 2 In some embodiments provided by the present invention, the first multi-way on-off regulating module 200 includes a first three-way valve 205 and a first three-way joint 206 connected in series to 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 joints of the first three-way joint 206, and the other end of the first three-way valve 205 is connected to the other joint of the first three-way joint 206;

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

[0087] In some embodiments of the present invention, the design of the first multi-way on-off regulating module 200 adopts a combination of a first three-way valve 205 and a first three-way connector 206. This design allows the flow direction of the heat exchange medium to be controlled through different ports of the first three-way valve 205 and the first three-way connector 206, thereby achieving precise regulation of the temperature of components such as the power conversion module and the battery 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, and 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 circulation or cutoff 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 in 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 the present invention, the second multi-way on-off regulating module 300 adopts the design of the second three-way valve 304, wherein 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 valve 304. Such a design provides the system with more adjustment options, so that the heat exchange medium can be distributed among more paths. By controlling the second three-way valve 304, precise control of the flow direction of the heat exchange medium 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 water chiller 1000, but also enhances its adaptability, enabling it to operate stably within a wider range of ambient temperatures.

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

[0090] In the present invention, the energy storage cabinet water chiller 1000 can achieve efficient thermal management of components such as power conversion modules and batteries inside the energy storage cabinet. Specifically:

[0091] When the ambient temperature is higher than the first temperature threshold, it means that the ambient temperature of the energy storage cabinet is relatively high. The embodiment of the present application can perform a series of operations to cool the inside of the energy storage cabinet. Among them, the first multi-way on-off adjustment module 200 can be connected to the first port 201, the second port 202 and the third port 203, and the second multi-way on-off adjustment module 300 can also be connected 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 refrigeration channel 600 and the second refrigeration channel 700 to absorb and transfer heat. At the same time, the compressor refrigeration module 400 can turn on the compressor 410 to enhance the heat dissipation effect of various components such as the power conversion module and the battery inside the energy storage cabinet. This intelligent temperature control strategy ensures that the temperature inside the energy storage cabinet can still be maintained within a suitable range in a high temperature environment.

[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, and the embodiment of the present application can switch to another mode to maintain the temperature inside the energy storage cabinet. In this case, the first multi-way on-off adjustment module 200 can be connected to the first port 201, the second port 202 and the fourth port 204, and the second multi-way on-off adjustment module 300 can be connected to the fifth port 301 and the seventh port 303. In this case, the dry cooler 500 is allowed to participate in refrigeration. In order to reduce unnecessary energy consumption and avoid overcooling, the compressor refrigeration module 400 can turn off the compressor 410. In this way, the heat exchange medium flows in the dry cooler refrigeration pipe 510, the first refrigeration channel 600 and the second refrigeration channel 700 to absorb and transfer heat. The temperature inside the energy storage cabinet can still be maintained in a low temperature environment to ensure that the heat dissipation requirements of components such as the power conversion module and the battery inside the energy storage cabinet are met.

[0093] It should be understood that this intelligent control strategy based on ambient temperature changes enables the energy storage cabinet water chiller 1000 to maintain a suitable temperature inside the energy storage cabinet under different environmental conditions by accurately controlling the flow path of the heat exchange medium and the operating state 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 for energy storage cabinets suitable for various environmental conditions.

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

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

[0096] In some embodiments of the present invention, the first multi-way on-off regulating module 200 adopts 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 enables 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, while the second multi-way on-off regulating module 300 adopts a second three-way connector 305 design, wherein 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. Such a configuration allows the heat exchange medium to achieve a more complex flow path inside the energy storage cabinet, thereby more finely controlling the cooling effect.

[0097] By using the four-way valve and the second three-way connector 305, the flow direction of the heat exchange medium can be dynamically adjusted according to the data fed back by the temperature sensor inside the energy storage cabinet to achieve more accurate temperature control. For example, when the ambient temperature is high, the heat exchange medium can be directed more to the area with greater heat dissipation demand, such as the power conversion module, through the four-way valve; and when the ambient temperature is low, the flow of the heat exchange medium can be reduced to avoid overcooling.

[0098] In summary, through the combined use of the four-way valve and the three-way connector, the embodiment of the present invention can provide 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 water chiller 1000, but also enhances the adaptability of the energy storage cabinet water chiller 1000, so that it can operate stably in a wider range of ambient temperatures, ensuring the performance and reliability of the components in the energy storage cabinet such as the power conversion module and the battery.

[0099] Reference Figure 4 In some embodiments provided by the present invention, the compressor refrigeration module 400 also includes a dehumidification evaporation unit 430, and the dehumidification evaporation unit 430 is arranged in a dehumidification evaporation pipe 440, and the dehumidification evaporation pipe 440 connects the first heat exchange pipe 110 at opposite ends of the primary side of the self-heat exchanger 100.

[0100] In some embodiments of the present invention, the energy storage cabinet water chiller 1000 may further include a dehumidification evaporation unit 430, and this design is mainly used to further improve the dehumidification capacity of the energy storage cabinet water chiller 1000. The dehumidification evaporation unit 430 is arranged in the dehumidification evaporation pipe 440, and the dehumidification evaporation pipe 440 connects the opposite ends of the primary side of the heat exchanger 100. Such a layout 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 realizing the dehumidification function.

[0101] In some embodiments, the dehumidification evaporation pipe 440 is connected in parallel with the compressor refrigeration pipe 450, and the compressor refrigeration pipe 450 can be a pipe for connecting the compressor 410 and the condenser 420 in series. This configuration allows the energy storage cabinet water chiller 1000 to perform cooling and dehumidification operations simultaneously when necessary. When the energy storage cabinet water chiller 1000 detects that the humidity inside the energy storage cabinet is too high, 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 can provide a dehumidification function. Some components inside the energy storage cabinet are very sensitive to humidity. If the energy storage cabinet is set in an environment with relatively high humidity, excessive humidity may cause the performance of the equipment to decline or even be damaged. By integrating the dehumidification function, the energy storage cabinet water chiller 1000 can more comprehensively control the internal environment to ensure that the equipment operates under ideal conditions.

[0102] It should be understood that by integrating the dehumidification evaporation unit 430 in the energy storage cabinet water chiller 1000, the present 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 high temperature and high humidity.

[0103] In some more specific embodiments, the gathering 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 arranged 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 arranged 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 first electronic expansion valve 461 and the second electronic expansion valve 462 are mainly used 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 of the first electronic expansion valve 461, the flow rate of the refrigerant can be accurately controlled, thereby accurately controlling the heat exchange capacity of the heat exchanger 100. In a high temperature environment, the first electronic expansion valve 461 can be fully or partially opened to allow more refrigerant to flow through the heat exchanger 100. In a low temperature environment, the flow rate may be reduced to reduce the cooling effect. It should be understood that in different operating modes, the opening of the first electronic expansion valve 461 of the embodiment of the present application will adjust the opening according to demand 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 refrigerant flow to the dehumidification evaporation unit 430.

[0105] Reference Figure 5 In some embodiments provided by the present invention, the energy storage cabinet water cooler 1000 also includes a heater 800 , and the heater 800 is disposed in the second heat exchange pipe 120 .

[0106] In some embodiments of the present invention, the design of the energy storage cabinet water chiller 1000 takes into account the requirements of an extremely low temperature environment, and a heater 800 component is particularly 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 working range under low temperature conditions, thereby ensuring the normal operation of the battery and power conversion module or other temperature-sensitive components.

[0107] It should be noted that the setting of the heater 800 allows the energy storage cabinet water cooler 1000 to actively input heat to the heat exchange medium in the second heat exchange pipe 120 when the external ambient temperature is low. In this way, even in cold climate conditions, it can be ensured that the heat exchange medium provides sufficient heat to maintain the temperature required by the internal equipment when flowing through the energy storage cabinet. By integrating the heater 800 into the second heat exchange pipe 120, the energy storage cabinet water cooler 1000 can implement a more flexible temperature control strategy. For example, when it is detected that the temperature of the power conversion module and battery and other components inside the energy storage cabinet drops below the set threshold, the thermal management control module can automatically start the heater 800 to increase the temperature of the battery and 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 water cooler 1000.

[0108] In addition, the addition of the heater 800 also enables the energy storage cabinet water cooler 1000 to cope with more complex climate conditions, and can ensure the stability of the internal environment of the energy storage cabinet regardless of hot summer or cold winter. This design is particularly suitable for energy storage cabinets installed outdoors or in areas with variable climates, and enhances the practicality and flexibility of the energy storage cabinet water cooler 1000.

[0109] It should be understood that by adding a heater 800 to the energy storage cabinet water chiller 1000 and arranging it in the second heat exchange pipe 120, the present 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 more specific embodiments of the present 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, and the embodiments of the present application can take more active measures to heat the inside of the energy storage cabinet. At this time, the first multi-way 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. In addition, the second multi-way 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. At the same time, the heater 800 is controlled to start, so as to input heat into the heat exchange medium and increase 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. It ensures that even in a very cold environment, the power conversion module and battery and other components inside the energy storage cabinet can be maintained at an ideal operating temperature.

[0111] Reference Figure 6 In some embodiments of the present invention, 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 kettle 311 .

[0112] In some embodiments of the present invention, 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 the first refrigeration channel 600 and the 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. Among them, the common refrigeration channel section 310 is the confluence point of the first refrigeration channel 600 and the second refrigeration channel 700, which allows the heat exchange medium from different heat exchange paths to mix here and return to the second multi-way on-off adjustment module 300. The key component of this design is the expansion kettle 311, which is set in the refrigeration channel section 310. The main function of the expansion kettle 311 is to adjust the volume change of the heat exchange medium, because the heat exchange medium will expand or contract due to temperature changes during the circulation process.

[0113] When the heat exchange medium is heated, it expands, and when it is cooled, it contracts. The expansion kettle 311 provides an additional space to accommodate the increased volume of the heat exchange medium due to the increase in temperature, thereby avoiding excessive pressure increase in the energy storage cabinet water cooler 1000, and helping to protect the pipes and components from damage due to excessive pressure. At the same time, when the heat exchange medium cools and contracts, the heat exchange medium in the expansion kettle 311 can return to the refrigeration channel section 310 to maintain a sufficient supply of heat exchange medium in the energy storage cabinet water cooler 1000.

[0114] In addition, the expansion kettle 311 can also play the role of constant pressure and exhaust, which can ensure the stability of the pressure inside the energy storage cabinet water cooler 1000, and release the gas that may accumulate in the energy storage cabinet water cooler 1000, so as to prevent the gas from forming air resistance in the energy storage cabinet water cooler 1000, thereby affecting the flow and heat exchange efficiency of the heat exchange medium. By integrating the expansion kettle 311 into the refrigeration channel section 310, the capacity stability and pressure buffering requirements of the heat exchange medium inside the energy storage cabinet water cooler 1000 can be met. The design of the present invention not only improves the thermal management capability of the energy storage cabinet water cooler 1000, but also enhances the safety and stability of the energy storage cabinet water cooler 1000. This configuration allows the energy storage cabinet water cooler 1000 to respond to temperature changes more effectively, while reducing the pressure fluctuation caused by the volume fluctuation of the heat exchange medium, ensuring that the internal equipment of the energy storage cabinet can obtain appropriate temperature control under various environmental conditions.

[0115] It should be understood that by providing an expansion kettle 311 in the refrigeration channel section 310 and connecting it to the first refrigeration channel 600 and the second refrigeration channel 700, the present invention provides an efficient and reliable thermal management solution, so that the energy storage cabinet water cooler 1000 can better adapt to different working conditions, thereby improving the efficiency and life of the entire energy storage cabinet water cooler 1000.

[0116] Reference Figure 7 The present invention also proposes a thermal management system for an energy storage cabinet, which is applied to perform thermal management on the energy storage cabinet and may include:

[0117] Energy storage cabinet water chiller 1000 as above;

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

[0119] The in-cabinet sensor 3000 is used to detect the in-cabinet sensor parameters corresponding to the energy storage cabinet;

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

[0121] The energy storage cabinet thermal management system proposed in the present invention is intended to provide accurate thermal management for the energy storage cabinet. This energy storage cabinet thermal management system not only includes the energy storage cabinet water chiller 1000 mentioned in the above embodiment, but also integrates the environmental sensor 2000, the cabinet sensor 3000 and the thermal management control module 4000 to form a closed-loop control energy storage cabinet thermal management system.

[0122] As the core part of the energy storage cabinet thermal management system, the energy storage cabinet water chiller 1000 is responsible for regulating the temperature inside the energy storage cabinet through the circulation of heat exchange medium. Among them, the cooperation between the heat exchanger 100, the first multi-way on-off adjustment module 200, the second multi-way on-off adjustment module 300, the compressor refrigeration module 400 and the dry cooler 500 is the key to achieving thermal management. These components work together to ensure that the components in the energy storage cabinet can obtain a suitable liquid inlet temperature under various environmental conditions to meet their specific requirements.

[0123] It should be noted that the environmental sensor 2000 and the in-cabinet sensor 3000 are responsible for monitoring the parameters of the external environment and internal state of the energy storage cabinet, such as temperature, humidity, etc. The data collected by these sensors are crucial to the thermal management control module 4000 because they provide real-time environmental and cabinet status information. The environmental sensor 2000 can detect external climate conditions, such as temperature changes, humidity changes, etc., while the in-cabinet sensor 3000 can monitor the temperature, humidity and possible changes in 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, and can capture changes in key parameters such as temperature and humidity, thereby obtaining environmental sensing parameters. This means that whether it is a hot summer or a cold winter, the environmental sensor 2000 can track the fluctuations of the external climate in real time and provide the necessary data support for the thermal management control module 4000. These data help the system understand the possible impact of the external environment on the energy storage cabinet, so as to take corresponding measures to maintain the stability of the internal environment.

[0125] The in-cabinet sensor 3000 focuses on the status inside the energy storage cabinet, which is reflected in the in-cabinet sensor parameters. Among them, the in-cabinet sensor parameters can accurately detect the temperature and humidity levels inside the cabinet, as well as any changes in the heat dissipation requirements that may affect the performance of the equipment, to ensure that the power conversion modules and batteries inside the energy storage cabinet operate under the required conditions. By monitoring these in-cabinet sensor parameters in real time, the in-cabinet sensor 3000 can promptly identify any abnormal conditions that may cause performance degradation or equipment damage, and take appropriate adjustment measures.

[0126] The thermal management control module 4000 of the present invention is the brain of the thermal management system of the energy storage cabinet, which analyzes and makes decisions based on the data provided by the environmental sensor 2000 and the internal sensor 3000, and then controls the various components of the energy storage cabinet 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-way on-off adjustment module, controlling the working state of the dry cooler 500 and the heater 800, or adjusting the operation of the dehumidification evaporation unit 430.

[0127] It should be pointed out that the energy storage cabinet thermal management system can significantly improve the performance and reliability of the energy storage cabinet. Through real-time monitoring and automatic adjustment, the energy storage cabinet thermal management system can adapt to changing environmental conditions and keep the temperature and humidity inside the energy storage cabinet within the 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, reduces 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 operating performance, making it a reliable solution suitable for various environmental conditions.

[0129] In some implementations provided by the present invention, the thermal management control module 4000 is configured as follows:

[0130] When the environmental sensor parameters reflect that the ambient temperature of the target environment is higher than the first temperature threshold, according to the environmental sensor parameters and the in-cabinet sensor parameters, 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 cooler 1000, the sixth port 302 and the seventh port 303 of the second multi-way on-off adjustment module 300 are connected, and the compressor 410 of the energy storage cabinet water cooler 1000 is turned on to achieve the temperature of the heat exchange medium in the first refrigeration channel 600 and the second refrigeration channel 700.

[0131] In some embodiments of the present invention, the thermal management control module 4000 is designed to intelligently adjust the operating state of the energy storage cabinet water chiller 1000 according to the real-time temperature data of the environment and the cabinet. Specifically, when the environmental sensor 2000 detects that the ambient temperature of the target environment is higher than the set first temperature threshold, the thermal management control module 4000 will initiate a series of actions to deal with this high temperature situation. The target environment is also the environment where the energy storage cabinet is located.

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

[0133] In the present invention, the thermal management control module 4000 cooperates with the energy storage cabinet water chiller 1000 to achieve efficient thermal management of the power conversion module and battery and other components 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. The embodiment of the present application can perform a series of operations through the energy storage cabinet water chiller 1000 to cool the inside of the energy storage cabinet. Among them, the first multi-way on-off adjustment module 200 can be connected to the first port 201, the second port 202 and the third port 203, and the second multi-way on-off adjustment module 300 can also be connected 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 refrigeration channel 600 and the second refrigeration channel 700 to absorb and transfer heat. At the same time, the compressor refrigeration module 400 can turn on the compressor 410, thereby enhancing the heat dissipation effect of various components such as the power conversion module and the battery inside the energy storage cabinet. This intelligent temperature control strategy ensures that the temperature inside the energy storage cabinet can still be maintained within a suitable range in a high temperature environment.

[0135] When the thermal management control module 4000 detects that 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 of the present application, the energy storage cabinet water chiller 1000 can be switched to another mode to maintain the temperature inside the energy storage cabinet. In this case, the first multi-way on-off adjustment module 200 can be connected to the first port 201, the second port 202 and the fourth port 204, and the second multi-way on-off adjustment module 300 can be connected to the fifth port 301 and the seventh port 303. In this case, the dry cooler 500 is allowed to participate in refrigeration. In order to reduce unnecessary energy consumption and avoid overcooling, the compressor refrigeration module 400 can turn off the compressor 410. In this way, the heat exchange medium flows in the dry cooler refrigeration pipe 510, the first refrigeration channel 600 and the second refrigeration channel 700 to absorb and transfer heat. The temperature inside the energy storage cabinet can still be maintained in a low temperature environment to ensure that the heat dissipation requirements of the power conversion module and battery and other components inside the energy storage cabinet are met.

[0136] When the thermal management control module 4000 detects that the ambient temperature drops below the third temperature threshold, it means that the ambient temperature of the energy storage cabinet is already very low. At this time, in the energy storage cabinet water chiller 1000, the first multi-way 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. In addition, the second multi-way 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. At the same time, the control heater 800 is started to input heat into the heat exchange medium to increase 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. It ensures that even in a very cold environment, the power conversion module and battery and other components inside the energy storage cabinet can be maintained at an ideal operating temperature.

[0137] It should be understood that this intelligent control strategy based on ambient temperature changes, the thermal management control module 4000 in conjunction with the energy storage cabinet water chiller 1000 can accurately control the flow path of the heat exchange medium and the operating state of the compressor 410 under different environmental conditions, so that the heat exchange medium can circulate through a specific path to perform heat exchange in the most effective way to maintain the appropriate 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 when flowing through the first cooling channel 600 and the second cooling channel 700. This not only helps to maintain the temperature inside the cabinet within a suitable range, but also allows the power conversion module and battery and other components inside the energy storage cabinet to be maintained at an ideal operating temperature.

[0139] It should be understood that the thermal management control module 4000 provided by the present invention realizes the control of the energy storage cabinet water chiller 1000 by intelligently analyzing and responding to environmental changes. This control strategy not only improves the performance and reliability of the energy storage cabinet in a high temperature environment, but also optimizes the energy efficiency and stability of the entire energy storage cabinet thermal management system.

[0140] In some implementations provided by the present invention, the thermal management control module 4000 is configured as follows:

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

[0142] It should be noted that the thermal management control module 4000 will analyze the real-time data from the environmental sensor 2000 and the in-cabinet sensor 3000, and then make corresponding adjustments. In this case, the thermal management control module 4000 will control the first multi-way on-off adjustment module 200 in the energy storage cabinet water chiller 1000, and only connect its first port 201 and the second port 202. Such a 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 turned off to reduce energy consumption and avoid unnecessary cooling, the dry cooler 500, as an auxiliary cooling device, uses ambient air to help maintain the temperature balance inside the energy storage cabinet. Among them, the dry cooler 500 is connected to the second heat exchange pipe 120 through its refrigeration pipe, and can use the low temperature of the external air to assist in reducing or stabilizing the temperature inside the energy storage cabinet without the need for the compressor 410. This cooling method is not only energy-saving, but also. In addition, the operation mode of the dry cooler 500 can be adjusted according to the environment and the real-time data of the sensor 3000 in the cabinet to ensure that the temperature inside the energy storage cabinet can be maintained within a suitable range without starting the compressor 410.

[0143] In a low temperature environment, the compressor 410 can be turned off to reduce excessive cooling. The dry cooler 500, as an auxiliary cooling device, uses ambient air to help maintain the temperature balance of the power conversion module and battery and other components inside the energy storage cabinet, which helps prevent the temperature of the power conversion module and battery and other components inside the energy storage cabinet from being too low, thereby protecting the internal power conversion module and other temperature-sensitive components from the influence of low temperature. Through intelligent control, the dry cooler 500 works in conjunction with the thermal management control module 4000 to adjust the cooling intensity according to actual needs, avoid excessive cooling, and ensure that the equipment can operate normally under low temperature conditions. By accurately controlling the flow path of the heat exchange medium, the heat exchange medium can circulate through a specific path to perform heat exchange in the most effective way to maintain the appropriate 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 the present invention. It realizes the control of the power conversion module and battery and other components inside the energy storage cabinet under low temperature conditions, improves the energy efficiency and reliability of the entire energy storage cabinet thermal management system, and ensures the stable operation of the energy storage cabinet under various environmental conditions.

[0145] In some embodiments provided by the present invention, the energy storage cabinet water cooler 1000 includes a heater 800, and the heater 800 is disposed in the second heat exchange pipe 120 of the energy storage cabinet water cooler 1000;

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

[0147] When the environmental sensor parameters reflect that the ambient temperature of the target environment is lower than the third temperature threshold, according to the environmental sensor parameters and the in-cabinet sensor parameters, 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 cooler 1000, 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 cooler 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 the present 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, which is integrated in the second heat exchange pipe 120 to provide necessary heat when the ambient temperature is below a certain threshold.

[0149] When the environment sensor 2000 detects that the ambient temperature is lower than 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, and will control the first multi-way on-off adjustment module 200 to connect its first port 201, second port 202 and third port 203. Such a configuration allows the heat exchange medium to circulate in the energy storage cabinet water chiller 1000. At the same time, the thermal management control module 4000 will start 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 the present invention, 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 a dehumidification evaporation pipe 440. The dehumidification evaporation pipe 440 connects the first heat exchange pipe 110 at opposite ends of the primary side of the self-heat exchanger 100; the thermal management control module 4000 is configured as follows:

[0151] When the in-cabinet sensor parameters reflect that the energy storage cabinet has entered a cabinet door closed state, the dehumidification evaporation unit 430 is started in the energy storage cabinet water chiller 1000 according to the environmental sensor parameters and the in-cabinet sensor parameters to adjust the humidity inside the energy storage cabinet.

[0152] It should be noted that the present invention also provides an implementation of a dehumidification function. In this configuration, the compressor refrigeration module 400 includes a dehumidification evaporation unit 430, which is arranged in a dehumidification evaporation pipe 440. The dehumidification evaporation pipe 440 is connected 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. Among them, the compressor refrigeration pipe 450 refers to a section of the 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 with each other.

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

[0156] The first internal cabinet component 5000 is provided in the first cooling channel 600 of the energy storage cabinet water chiller 1000 in the energy storage cabinet thermal management system;

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

The functions specifically implemented by the embodiment of the energy storage cabinet are the same as those of the above energy storage cabinet thermal management system, and the beneficial effects achieved are also the same as those achieved by the above energy storage cabinet thermal management system.
