Description

Technical Field

[0001] The utility model relates to the technical field of new energy batteries, and in particular to an energy storage container thermal management system and an energy storage container. Background Art

[0002] In recent years, containers have become widely used not only for logistics and transportation, but also for housing, equipment rooms, and information centers. Energy storage containers integrate energy storage units within them, enabling rapid integration and commissioning of energy storage equipment. During operation, thermal management of the battery cell modules that comprise the battery cluster is a key factor in determining performance, safety, lifespan, and cost.

[0003] In conventional energy storage container assembly, battery cells are typically stacked into modules and then placed in plug-in boxes. These plug-in boxes are then inserted into grid-like racks within the container to form battery clusters. Thermal management of the battery modules typically utilizes air cooling / heating technology to regulate the container's internal temperature, combined with liquid cooling / heating technology to achieve uniform heat exchange for the battery modules within each plug-in box.

[0004] In conventional energy storage containers, the air cooling / heating system often blocks the cold and hot air generated by the plug-in box or lid, preventing direct contact with the internal battery cells, resulting in poor air cooling / heating efficiency. Furthermore, liquid cooling / heating solutions typically employ a cold plate at the bottom of the plug-in box for heat exchange and temperature equalization. This single heat exchange location allows for poor overall temperature within the box, leading to temperature differences between battery clusters and between the inside and outside of the plug-in box. This can easily lead to condensation on the bottom of the plug-in box, which houses the battery modules, compromising the safety of the energy storage container. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Figures 1 to 6 As shown, an embodiment of the present invention provides a thermal management system for an energy storage container, including a battery rack 1, a plug-in tray 2 and a thermal management component 3.

[0031] The battery rack 1 is provided with multiple layers of plug-in slots 11 , the plug-in tray 2 is plugged into the plug-in slots 11 , and a liquid cooling channel 21 is provided in the plug-in tray 2 .

[0032] The thermal management assembly 3 includes a thermal management unit 31, which includes a first heat exchange box 311, a second heat exchange box 312, and a refrigerant pipe 313. The refrigerant pipe 313 passes through the first and second heat exchange boxes 311, 312 and is connected to a heat exchanger 314 disposed within the first and second heat exchange boxes 311, 312. An air inlet pipe 3111 is provided on one side of the first heat exchange box 311, and an air outlet pipe 3112 is provided on the other side, facing the battery rack 1. A liquid inlet pipe 3121 is provided on one side of the second heat exchange box 312, and a liquid outlet pipe 3122 is provided on the other side. The liquid inlet pipe 3121 and the liquid outlet pipe 3122 are respectively connected to the inlet and outlet of the liquid cooling channel 21.

[0033] In an embodiment of the present invention, the battery rack 1, which is provided in an energy storage container to support battery modules and form a battery cluster, and its matching structure, as well as the corresponding structure for temperature management within the energy storage container, are optimized. Specifically, for the installation of the battery cell module 5, multiple plug-in trays 2 are used to position and install the battery cell module 5. The module is then directly inserted and installed on the battery rack 1 from one side of the plug-in column 11. The inlet and outlet of the liquid cooling channel 21 provided on one side of the plug-in tray 2 are then connected to the liquid inlet pipe 3121 and liquid outlet pipe 3122 of the thermal management unit 31 through pipes to complete the installation in the box. Compared to the traditional plug-in box structure, it eliminates components such as the fully enclosed box cover and explosion-proof valve, reducing the number of module components and the complexity of the installation in the box. Furthermore, the insertion tray 2 is provided with a plurality of module mounting grooves 22, and the liquid cooling channel 21 flows through the bottom of the module mounting groove 22. By providing the corresponding module mounting groove 22, the corresponding installation of the battery module 5 is facilitated, and the limiting fixation is achieved in the horizontal direction to ensure the assembly stability. Furthermore, the insertion tray 2 can also be provided with a protruding limiting pin 23, and the limiting pin 23 is provided in plurality and arranged around the module mounting groove 22. By providing the limiting pin 23, it can be docked with the corresponding mounting hole position on the battery rack 1 after being assembled in place to achieve the positioning of the insertion tray 2 in the insertion direction, further improving the assembly stability. Among them, the limiting pin 23 can be retractable, and is in an extended state in the normal state. When encountering an obstacle during the insertion process, it can be retracted downward to the bottom of the top surface of the insertion tray 2 to avoid interference. After the obstacle passes and reaches the bottom of the assembly hole, it is reset and extended under the elastic force of the internal spring to be docked and fixed, thereby improving practicality.

[0034] Furthermore, when the energy storage container heat dissipation system is in operation, the first heat exchange box 311 and the second heat exchange box 312 are provided to introduce external air and liquid cooling circulation, respectively, and the refrigerant circulation is introduced in conjunction with the refrigerant pipe 313 to perform air heat exchange and liquid heat exchange with the internal battery cluster. The refrigerant medium enters the heat exchanger 314 provided inside the first heat exchange box 311 and the second heat exchange box 312 through the refrigerant pipe 313 and maintains circulation. On the one hand, an air inlet pipe 3111 is provided on one side of the first heat exchange box 311. A fan is provided at one end of the air inlet pipe 3111 to introduce external air. When the external air passes through the first heat exchange box 311, it exchanges heat with the refrigerant in the internal heat exchanger 314. Finally, the air, which has been heated or cooled, is discharged into the energy storage container through the air outlet pipe 3112 and blown toward the battery rack 1, thereby achieving control of the overall ambient temperature within the energy storage container and sufficient heat exchange with the battery cell module 5. On the other hand, the second heat exchange box 312 is provided with a liquid inlet pipe 3121 and a liquid outlet pipe 3122 on both sides. After docking with the plug-in tray 2, a pump can be provided to provide power to connect the liquid cooling channel 21 in the plug-in tray 2 to the external liquid cooling cycle, or directly form a liquid cooling internal cycle. When the liquid passes through the second heat exchange box 312, it exchanges heat with the refrigerant in the internal heat exchanger 314. The temperature-regulated liquid is passed into the liquid cooling channel 21 through the liquid outlet pipe 3122, and the battery module 5 is heat-exchanged and evenly heated from the bottom to achieve heating / cooling of the battery module 5. The liquid after heat exchange returns to the second heat exchange box 312 through the liquid inlet pipe 3121 for circulation. Through the setting of the thermal management component 3, the air cooling / heating technology and liquid cooling / heating dual regulation of the space temperature in the energy storage container and the battery module 5 supported by the plug-in tray 2 on the battery rack 1 can be achieved. The energy storage container is cooled or heated at the room level using air cooling / heating. Direct installation via the plug-in tray 2 increases the heat exchange contact surface with the battery module 5, reducing the temperature difference between battery clusters and between the interior and exterior of the plug-in tray 2. This effectively removes moisture and prevents condensation on the bottom of the plug-in tray 2. Simultaneously, the thermal management unit 31 utilizes the same refrigerant cycle to cool or heat the battery module 5 using liquid cooling, effectively reducing the energy consumption of the energy storage container's thermal management while improving its thermal management capabilities. This solution addresses the problem of poor thermal management effectiveness in existing energy storage containers due to design and structural defects.

[0035] Optionally, the refrigerant pipe 313 includes a refrigerant inlet pipe 3131 and a refrigerant outlet pipe 3132. The refrigerant inlet pipe 3131 passes through two branches, respectively, into the first heat exchange box 311 and the second heat exchange box 312, and then passes out of the refrigerant outlet pipe 3132 to connect. An electrically controlled valve 315 is provided at the connection between the refrigerant inlet pipe 3131 and the refrigerant outlet pipe 3132 and the two branches. For example, in an embodiment of the present invention, the refrigerant pipe 313 is connected to an external refrigerant supply device at both ends of the refrigerant inlet pipe 3131 and the refrigerant outlet pipe 3132 to form a circulation system. The refrigerant introduced through the refrigerant inlet pipe 3131 is respectively passed through the two front branches 313a to the heat exchangers 314 in the first heat exchange box 311 and the second heat exchange box 312, and then enters the refrigerant outlet pipe 3132 through the rear branch 313b at the end of the heat exchanger 314 and is discharged. By setting the electric control valve 315 at the diversion point of the two front branch pipes 313a and the refrigerant inlet pipe 3131, and at the confluence point of the rear branch pipe 313b and the refrigerant outlet pipe 3132, the thermal management unit 31 can regulate the opening and closing of the electric control valve 315 of the air cooling / heat cycle and the liquid cooling / heat cycle according to actual needs, so as to realize independent or simultaneous operation of air cooling / heat and liquid cooling / heat to meet the air cooling / heat and liquid cooling / heat functions.

[0036] Optionally, the thermal management component 3 also includes a battery management system 32. The detection terminal of the battery management system 32 is disposed on the battery rack 1. The battery management system 32 is configured to control the opening and closing of the electronically controlled valve 315 by detecting the temperature and temperature rise rate of the battery module 5 on the insertion tray 2. For example, in an embodiment of the present invention, the air cooling / heating and liquid cooling / heating cycle control can be accurately and automatically regulated based on the temperature and temperature rise rate of the battery module 5, autonomously selecting a thermal management method with lower energy consumption. For example, when the temperature rise rate is not high within the energy storage container, only air cooling is used for heat dissipation. When air cooling fails to meet the requirements, the system switches to simultaneous air cooling and liquid cooling. This reduces the energy consumption of the container's thermal management and improves the battery cell temperature management level. According to actual tests, when air cooling and liquid cooling are implemented simultaneously, the maximum temperature difference between individual cells in the battery module 5 can be controlled to approximately 3°C.

[0037] Optionally, the ends of the liquid inlet pipe 3121 and the liquid outlet pipe 3122 are arranged at the bottom of the battery rack 1, and liquid cooling risers 12 that match the ends of the liquid inlet pipe 3121 and the liquid outlet pipe 3122 are provided on both sides of the plug-in column 11. The liquid cooling risers 12 are provided with liquid cooling interfaces 121 that correspond one-to-one with the plug-in column 11. For example, in an embodiment of the present utility model, the liquid inlet pipe 3121 and the liquid outlet pipe 3122 are led out and arranged at the bottom of the energy storage container, and their ends extend to the bottom of the battery rack 1, which is convenient for layout. At the same time, after being introduced as the main line to the bottom of the battery rack 1, it can be connected to the liquid cooling riser 12 on the battery rack 1 by means of a hose or direct docking, and then connected to the liquid cooling channel 21 on the plug-in tray 2 through the liquid cooling interface 121 of the liquid cooling riser 12, thereby realizing structural modular assembly and improving assembly efficiency and practicality.

[0038] Optionally, the opening direction of the air outlet duct 3112 is perpendicular to the insertion direction of the insertion tray 2. For example, in an embodiment of the present invention, the air outlet duct 3112 is disposed above the liquid inlet duct 3121 and the liquid outlet duct 3122. It primarily draws in heat-exchanged air from the top of the energy storage container. At the same time, its airflow direction is perpendicular to the insertion direction of the insertion tray 2. This allows the air introduced from above the battery rack 1 to fully contact the battery cell modules 5 placed horizontally on the insertion tray 2, ensuring a sufficient heat exchange area and improving heat exchange efficiency.

[0039] The present invention also provides an energy storage container, including: Figures 1 to 6 The illustrated energy storage container thermal management system also includes a housing 4 and a cell module 5. The battery rack 1 is disposed within the housing 4, and the cell module 5 is mounted on a mounting plate 2. By way of example, the energy storage container heat dissipation system provided by the present invention is used in conjunction with the housing 4 to form an energy storage container. The battery rack, which is disposed within the energy storage container to support the battery modules and form a battery cluster, and its matching structure, as well as the corresponding structure for temperature management within the energy storage container, are optimized. Regarding the installation of the cell module, compared to traditional plug-in box structures, the fully enclosed box cover and explosion-proof valve are eliminated, reducing the number of module components and the complexity of installation.

[0040] By setting up this thermal management component, it is possible to implement dual regulation of the space temperature inside the energy storage container and the battery modules supported by the plug-in tray on the battery rack using air cooling / heating technology and liquid cooling / heating. The energy storage container is cooled or heated at the room level in the form of air cooling / heating, and combined with the form of direct installation through the plug-in tray, the heat exchange contact surface with the battery modules is increased, the temperature difference between battery clusters and between the inside and outside spaces of the plug-in tray is reduced, and effective dehumidification is achieved to avoid condensation at the bottom of the plug-in tray. At the same time, the thermal management unit uses the same set of refrigerant circulation to achieve cooling or heating of the battery modules in a liquid cooling manner, effectively reducing the thermal management energy consumption of the energy storage container while improving the thermal management level of the energy storage container. It can solve the problem of poor thermal management effect caused by design structural defects in existing energy storage containers in the relevant technology.

[0041] Optionally, a plug-in opening 41 is provided on one side of the box body 4, and the ends of the liquid inlet pipe 3121 and the liquid outlet pipe 3122 are provided on the side of the bottom plate of the box body 4 close to the plug-in opening 41. For example, in an embodiment of the present utility model, by using one side wall of the box body 4 as the entry surface, the side plate of the box body 4 is disassembled to form the plug-in opening 41, which serves as the main entry channel for the plug-in tray 2 and the battery module 5, thereby facilitating the overall entry assembly. At the same time, by arranging the ends of the liquid inlet pipe 3121 and the liquid outlet pipe 3122 on the side of the bottom plate of the box body 4 close to the plug-in opening 41, after the insertion of the plug-in tray 2 is completed, sufficient space can be provided to facilitate the staff to connect the liquid inlet pipe 3121, the liquid outlet pipe 3122 to the inlet and outlet pipes of the liquid cooling channel 21 on the plug-in tray 2 from the open side of the plug-in opening 41, thereby further improving practicality.

[0042] Optionally, multiple battery racks 1 are provided and arranged at intervals within the housing 4, with the first heat exchange box 311 and the second heat exchange box 312 being disposed on one side of the arrangement direction of the multiple battery racks 1. For example, in an embodiment of the present invention, the first heat exchange box 311, the second heat exchange box 312, and the associated thermal management components 3, such as piping and a thermal management system, are all disposed on one side of the energy storage container, facilitating centralized assembly, maintenance, and piping routing.
