Description

Technical Field

[0001] This utility model belongs to the field of new energy storage technology, specifically relating to an automatic temperature-controlled liquid-cooled outdoor energy storage cabinet. Background Technology

[0002] Outdoor server racks are devices that provide an outdoor physical working environment and security system for wireless communication sites or wired network sites, directly exposed to the influence of natural climate. They are typically installed in locations such as roadsides, parks, rooftops, mountains, and flatlands.

[0003] In existing technology, battery modules are generally installed inside outdoor cabinets to power the electrical equipment inside the cabinet. However, the operation of battery modules generates a lot of heat. Outdoor cabinets usually dissipate heat naturally through ventilation vents, which has a limited cooling effect. This not only fails to effectively cool the inside of the cabinet, but also poses a safety hazard if the battery module temperature gets too high, which may lead to battery combustion or explosion. Utility Model Content

[0004] This utility model provides an automatic temperature-controlled liquid-cooled outdoor energy storage cabinet, which aims to solve the technical problem in the prior art that the cabinet cannot effectively cool the inside, resulting in excessively high battery module temperatures.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic temperature-controlled liquid-cooled outdoor energy storage cabinet is provided, comprising a chassis, a liquid-cooling module, and a control module. The chassis houses the battery modules; the liquid-cooling module is located within the chassis and is used to cool the battery modules; the control module is located within the chassis and is electrically connected to both the liquid-cooling module and the battery modules.

[0006] In one possible implementation, the chassis is provided with multiple brackets, which are spaced apart along the height of the chassis, and the brackets are respectively used to support the battery module, the liquid cooling module and the control module.

[0007] In one possible implementation, the bracket has an L-shaped cross-section, and the bracket is arranged parallel to the length of the chassis.

[0008] In one possible implementation, the liquid cooling module includes a liquid cooling unit, liquid cooling pipelines, and coolant; the liquid cooling unit is equipped with a temperature controller for adjusting the temperature of the coolant; the liquid cooling pipelines are connected to the liquid cooling unit and to the battery module; and the coolant is filled in the liquid cooling pipelines.

[0009] In one possible implementation, the liquid cooling pipeline includes a temperature sensor and several valves; the temperature sensor is used to monitor the temperature of the coolant; and the several valves are configured one-to-one with the battery module.

[0010] In one possible implementation, the battery module includes a liquid cooling plate, which has a hollow structure and is provided with an inlet and an outlet, which are respectively connected to the liquid cooling pipeline.

[0011] In one possible implementation, the battery module and the bracket are slidably connected via a slide rail structure.

[0012] In one possible implementation, there are multiple battery modules.

[0013] In one possible implementation, the chassis is equipped with a display screen.

[0014] In one possible implementation, the chassis is further provided with a heat sink, and the heat sink has multiple heat dissipation holes.

[0015] This embodiment provides an automatic temperature-controlled liquid-cooled outdoor energy storage cabinet. Compared with existing technologies, this application includes a chassis, a liquid-cooling module, and a control module. The coolant in the liquid-cooling module, driven by a circulating pump, flows through pipes surrounding the battery module, carrying away the heat generated by the battery during operation and achieving initial cooling. The control module monitors the battery module temperature in real time. When the battery temperature rises, the control module sends instructions to the liquid-cooling module to adjust the coolant flow rate or activate more heat dissipation components to enhance the cooling effect.

[0027] The present invention provides an automatic temperature-controlled liquid-cooled outdoor energy storage cabinet.

[0028] Please refer to the following: Figures 1 to 3 An automatic temperature-controlled liquid-cooled outdoor energy storage cabinet includes a chassis 1, a liquid-cooling module 2, and a control module. The chassis 1 is used to house battery modules 10; the liquid-cooling module 2 is located inside the chassis 1, and the liquid-cooling unit 21 is used to cool the battery modules 10; the control module is located inside the chassis 1 and is electrically connected to both the liquid-cooling module 2 and the battery modules 10.

[0029] This embodiment provides an automatic temperature-controlled liquid-cooled outdoor energy storage cabinet. Compared with the prior art, this application includes a chassis 1, a liquid-cooling module 2, and a control module. The coolant in the liquid-cooling module 2, driven by a circulation pump, flows through the pipes surrounding the battery module 10, carrying away the heat generated by the battery during operation and achieving initial cooling. The control module monitors the temperature of the battery module 10 in real time. When the battery temperature rises, the control module sends a command to the liquid-cooling module 2 to adjust the flow rate and volume of the coolant, or to activate more heat dissipation components to enhance the cooling effect. When the battery temperature drops to a suitable range, the control module adjusts the working state of the liquid-cooling module 2 to maintain stable battery operation within a suitable temperature range. This automatic temperature-controlled liquid cooling system can accurately control the temperature of the battery module 10, avoiding problems such as decreased battery performance and shortened lifespan due to excessive temperature. A stable temperature environment can also improve battery charging and discharging efficiency, ensure battery safety, and reduce the risk of safety accidents such as fires caused by overheating. Furthermore, the system is integrated into the chassis 1, has a compact structure, does not occupy excessive space, and facilitates equipment installation and maintenance.

[0030] In some embodiments, the chassis 1 is provided with a plurality of brackets 11, which are spaced apart along the height direction of the chassis 1. The plurality of brackets 11 are respectively used to support the battery module 10, the liquid cooling module 2 and the control module.

[0031] During system installation, the battery module 10, liquid cooling module 2, and control module are placed on brackets 11 at corresponding heights. The brackets 11 are spaced apart along the height of the chassis 1 to form a stable support structure. During system operation, each module remains in a fixed position thanks to the brackets 11 and will not shift due to vibration or other factors.

[0032] This design enables a layered arrangement of modules within chassis 1, resulting in a more organized and orderly layout of components, facilitating installation and maintenance. Simultaneously, the support of bracket 11 enhances the overall stability of the system and prevents interference between components.

[0033] Furthermore, the bracket 11 has an L-shaped cross-section, and its length is parallel to the length of the chassis 1. During installation, the right-angled sides of the L-shaped bracket 11 contact the inner wall of the chassis 1 and the components, respectively. Utilizing the stability of the L-shape, the battery module 10, liquid cooling module 2, and control module are firmly fixed inside the chassis 1. Because its length is parallel to the length of the chassis 1, the supporting force is evenly distributed within the length of the chassis 1.

[0034] The L-shaped structure provides excellent structural support, making component installation more secure and preventing wobbling. The parallel arrangement makes full use of the space in chassis 1, rationally planning component layout, improving the utilization rate of space within chassis 1, and facilitating the routing and organization of cables, etc.

[0035] In other embodiments, the liquid cooling module 2 includes a liquid cooling unit 21, a liquid cooling pipeline 22, and a coolant; the liquid cooling unit 21 is equipped with a thermostat for adjusting the temperature of the coolant; the liquid cooling pipeline 22 is connected to the liquid cooling unit 21 and is also connected to the battery module 10; the coolant is filled in the liquid cooling pipeline 22.

[0036] The thermostat inside the liquid cooling unit 21 adjusts the coolant temperature according to the instructions of the control module. The coolant, with the temperature adjusted, flows into the liquid cooling pipe 22 connected to the liquid cooling unit 21 under the action of circulation power, and then enters the battery module 10 through the connection between the pipe and the battery module 10 to remove heat. After that, it flows back to the liquid cooling unit 21 to readjust the temperature, forming a cycle.

[0037] Through the cooperation of liquid cooling unit 21, pipelines and coolant, the battery module 10 is continuously cooled and cooled. The presence of the thermostat ensures that the coolant can maintain a suitable temperature, ensuring stable cooling effect and ensuring that the battery operates at a suitable temperature.

[0038] Specifically, a thermostat, also known as a temperature regulator, is a valve that controls the flow path of coolant. As an automatic temperature control device, it typically contains a temperature-sensing component that opens or closes the flow of air, gas, or liquid by means of expansion or contraction.

[0039] In some embodiments, the liquid cooling pipeline 22 includes a temperature sensor and several valves; the temperature sensor is used to monitor the temperature of the coolant; and the several valves are configured one-to-one with the battery module 10.

[0040] A temperature sensor monitors the temperature of the coolant in the liquid cooling pipe 22 in real time and feeds the data back to the control module. When different battery modules 10 have different heat dissipation conditions, the valves corresponding to each battery module 10 are opened or closed, or their opening degree is adjusted, under the control of the control module, to control the flow rate of the coolant flowing through the corresponding battery module 10.

[0041] Temperature sensors accurately monitor coolant temperature, providing precise data for the control module. Valve settings allow for flexible adjustment of cooling intensity based on the actual temperature of each battery module 10, achieving precise temperature control and improving cooling efficiency and targeted performance.

[0042] Please see Figure 3 and Figure 4 In some embodiments, the battery module 10 includes a liquid cooling plate 100, which has a hollow structure and is provided with an inlet 101 and an outlet 102, which are respectively connected to the liquid cooling pipeline 22.

[0043] Coolant flows from the inlet 101 of the liquid cooling pipe 22 into the hollow structure of the liquid cooling plate 100, flows in the hollow cavity, absorbs the heat generated by the battery module 10, and then flows out from the outlet 102 back to the liquid cooling pipe 22 to continue the circulation.

[0044] The liquid cooling plate 100 increases the contact area between the coolant and the battery module 10, enabling more efficient heat exchange, effectively improving the cooling effect, ensuring the temperature stability of the battery module 10, and thus improving battery performance and lifespan.

[0045] In other embodiments, the battery module 10 and the bracket 11 are slidably connected via a slide rail structure. When installing the battery module 10, it is easily pushed into the corresponding position of the bracket 11 along the slide rail and fixed; when maintenance or replacement of the battery module 10 is required, the battery module 10 is slid out along the slide rail, which is convenient and quick.

[0046] The sliding rail structure simplifies the installation, disassembly, and maintenance of the battery module 10, greatly reducing maintenance time and labor costs. It also facilitates individual inspection or replacement of the battery module 10 without affecting other components.

[0047] Specifically, there are multiple battery modules 10. Multiple battery modules 10 work simultaneously, generating heat. The liquid cooling module 2 and the control module work together to monitor and regulate the temperature of each battery module 10, ensuring that all battery modules 10 are within a suitable temperature range.

[0048] Multiple battery modules 10 can increase the system's energy storage or output capacity to meet higher power demands. At the same time, the unified management of the liquid cooling system ensures the stable operation of multiple modules and improves the overall system performance and reliability.

[0049] Specifically, the chassis 1 is equipped with a display screen 12. The control module transmits key information about the system operation, such as the temperature of the battery module 10 and the working status of the liquid cooling module 2, to the display screen 12 for real-time display and easy viewing by operators.

[0050] The display screen 12 provides operators with intuitive system operation information, making it easy to keep track of the system's working status at any time, detect and handle abnormalities in a timely manner, and improve the ease of use and monitorability of the system.

[0051] Specifically, the chassis 1 is also equipped with a heat sink 13, which has multiple ventilation holes.

[0052] Some of the heat carried away by the liquid cooling module 2 is dissipated to the external environment through the heat sink 13. The hot air inside the chassis 1 exchanges with the cold air outside through the heat dissipation holes, which helps to reduce the temperature inside the chassis 1.

[0053] The heat sink 13 and heat dissipation holes increase the heat dissipation path of the system. Together with the liquid cooling module 2, they further improve heat dissipation efficiency, reduce the overall temperature inside the chassis 1, create a better working environment for each component, and ensure stable system operation.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
