Description

Technical Field

[0001] This invention relates to the field of energy storage container temperature regulation technology, and in particular to an energy storage container with a temperature self-regulation module. Background Technology

[0002] As the core integrated carrier of electrochemical energy storage systems, energy storage containers are mainly used to encapsulate battery modules, electronic control systems, and safety auxiliary equipment. They have the core functions of sealing and protection, structural support, environmental isolation, and explosion-proof and flame-retardant properties. They can adapt to complex outdoor working conditions, ensure the stable and safe operation of energy storage equipment, and are the core basic unit of large-scale energy storage power stations.

[0003] Currently, the mainstream heat dissipation methods for energy storage containers are air cooling and simple liquid cooling, mostly employing a single temperature control mode of top air conditioning and whole-cabin convection cooling. While this method is simple in structure and easy to deploy, it has significant drawbacks in practical applications. First, the temperature control method is extremely simplistic, relying heavily on fixed-power refrigeration equipment, and cannot adaptively adjust based on the temperature rise of battery modules in different zones or the ambient temperature difference, resulting in poor targeted heat dissipation. Second, the temperature control effect is limited; heat distribution inside the container is uneven, with insufficient heat dissipation for battery modules at the corners and bottom, leading to cell temperature differences of 3-5°C. Prolonged operation with these temperature differences accelerates cell aging, reduces battery cycle life, and can easily trigger thermal runaway risks under extreme conditions.

[0004] Meanwhile, existing cooling systems, with their complex air ducts, refrigeration units, and piping structures, occupy a significant amount of internal space within the container, compressing the space available for battery modules and drastically reducing the container's energy density. In summary, existing energy storage container temperature control technology suffers from core problems such as a single control method, poor temperature uniformity, and low space utilization, making it difficult to adapt to the operational needs of large-capacity, high-density energy storage equipment, and thus requiring urgent optimization and improvement. Summary of the Invention

[0005] The technical problem to be solved by this invention is that existing energy storage container temperature control technology suffers from problems such as a single temperature control method, poor temperature uniformity, and low space utilization.

[0006] The technical solution adopted by the present invention to solve its technical problem is: an energy storage container body with a temperature self-regulating module, including an outer main body with an energy storage module installed inside, a number of horizontally arranged strip-shaped top mounting grooves on the upper surface of the outer main body, a top liquid collection tank with a built-in circulating liquid pump fixedly installed on the inner wall of the left side of the outer main body, a flow guide shroud with a built-in fan fixedly installed on the inner wall of the right side of the outer main body, two inlet pipes fixedly installed at the inner corner of the left side of the outer main body, two return pipes fixedly installed at the inner corner of the right side of the outer main body, horizontal flow guide pipes fixedly installed on both sides of the inner top surface of the outer main body, and a serpentine top heat dissipation pipe arranged inside the strip-shaped top mounting grooves.

[0007] Furthermore, the two ends of the inlet pipe are connected to the outlet of the circulating liquid pump and the liquid-cooled inlet of the energy storage module, and the two ends of the return pipe are connected to the inlet of the serpentine top heat sink and the liquid-cooled return port of the energy storage module.

[0008] Furthermore, an inner heat dissipation vent is provided on the inner wall of the strip-shaped mounting groove, and the inner heat dissipation vent is fixedly connected to the air outlet of the horizontal guide pipe.

[0009] Furthermore, a gap is left between the strip-shaped upper mounting groove and the serpentine top heat dissipation pipe.

[0010] Furthermore, several temperature sensor controllers are fixedly installed on the top surface of the outer main housing.

[0011] Furthermore, an electronic air valve controlled by a temperature sensor controller is fixedly installed inside the inner heat dissipation vent.

[0012] Furthermore, a lateral drain outlet is provided on the outer wall of the main casing, which is connected to the inside of the strip-shaped upper mounting groove. The lateral drain outlet is staggered with the inner heat dissipation outlet.

[0013] Furthermore, an external air inlet is provided on the outer wall of the main outer casing, which is connected to the air inlet of the air guide shroud, and a dustproof and waterproof cover is installed on the outside of the external air inlet.

[0014] Furthermore, an external dustproof mesh is installed on the inner heat dissipation vent, and a humidity sensor module is installed inside the inner heat dissipation vent.

[0015] Furthermore, the outlet of the serpentine top-mounted heat dissipation pipe is fixedly connected to the inside of the top-side liquid collection tank.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The energy storage container shown includes an external main body 1 with an internally installed energy storage module 2. The external main body 1 is a cuboid shell structure with several horizontally arranged strip-shaped mounting grooves 11 on its upper surface. The strip-shaped mounting grooves 11 are arranged parallel to each other along the width direction of the external main body 1. A serpentine top heat dissipation pipe 8 is installed inside the strip-shaped mounting grooves 11. The serpentine top heat dissipation pipe 8 is arranged to bend back and forth along the length direction of the strip-shaped mounting grooves 11. A gap is left between the strip-shaped mounting grooves 11 and the serpentine top heat dissipation pipe 8, so that airflow can pass through the inside of the strip-shaped mounting grooves 11 and flow over the surface of the serpentine top heat dissipation pipe 8, carrying away the heat carried by the coolant.

[0026] A top-side liquid collection tank 3 with a built-in circulating liquid pump 31 is fixedly installed on the inner left side of the outer main housing 1, and a flow guide shroud 4 with a built-in fan 41 is fixedly installed on the inner right side of the outer main housing 1. Two inlet pipes 5 are fixedly installed at the inner corner of the left side of the outer main housing 1, and the two ends of the inlet pipes 5 are respectively connected to the outlet of the circulating liquid pump 31 and the liquid cooling inlet of the energy storage module 2; two return pipes 6 are fixedly installed at the inner corner of the right side of the outer main housing 1, and the two ends of the return pipes 6 are respectively connected to the inlet of the serpentine top heat sink 8 and the liquid cooling return port of the energy storage module 2. The outlet of the serpentine top heat sink 8 is fixedly connected to the inside of the top-side liquid collection tank 3. After the circulating liquid pump 31 starts, the coolant flows out from the top liquid collection tank 3, and after being pressurized by the circulating liquid pump 31, it is sent into the liquid cooling channel of the energy storage module 2 through the inlet pipe 5. After absorbing the heat generated by the energy storage module 2, the coolant enters the serpentine top heat dissipation pipe 8 through the return pipe 6. When flowing in the serpentine top heat dissipation pipe 8, it exchanges heat with the outside air and cools down. Finally, it flows back to the top liquid collection tank 3, forming a closed liquid cooling heat dissipation circuit.

[0027] Horizontal guide pipes 7 are fixedly installed on both sides of the inner top surface of the outer main housing 1. An inner heat dissipation vent 12 is provided on the inner wall of the strip-shaped upper mounting groove 11, and the inner heat dissipation vent 12 is fixedly connected to the air outlet of the horizontal guide pipes 7. An external air inlet 14 is provided on the outer wall of the outer main housing 1, which is connected to the air inlet of the guide shroud 4. A dustproof and waterproof cover 15 is installed on the outside of the external air inlet 14 to prevent external dust and rainwater from entering the housing. A side drain outlet 13 is also provided on the outer wall of the outer main housing 1, which is connected to the inside of the strip-shaped upper mounting groove 11. The side drain outlet 13 is arranged in opposite directions to the inner heat dissipation vent 12, facilitating the timely drainage of water accumulated inside the strip-shaped upper mounting groove 11.

[0028] Several temperature sensor controllers 18 are fixedly installed on the top surface inside the outer main enclosure 1. The temperature sensor controllers 18 are arranged at intervals along the length of the outer main enclosure 1 to detect the temperature of different areas inside the enclosure in real time. An electronic air valve 19 controlled by the temperature sensor controllers 18 is fixedly installed inside the inner heat dissipation vent 12. An external dustproof net 16 is installed on the inner heat dissipation vent 12, and a humidity sensor module 17 is installed inside the inner heat dissipation vent 12.

[0029] The temperature sensor controller 18 collects temperature signals from various areas inside the enclosure in real time and transmits them to the control system. The control system compares the collected temperature values ​​with preset temperature thresholds. When the internal temperature of the enclosure exceeds the first preset threshold, the control system controls the electronic air valve 19 to open and simultaneously controls the fan 41 to start. External air enters the air guide shroud 4 through the external air inlet 14, is pressurized by the fan 41, and then sent into the horizontal air guide pipe 7. After passing through the horizontal air guide pipe 7, it is discharged through the inner heat dissipation port 12 and enters the strip-shaped upper mounting groove 11. When the airflow passes over the surface of the serpentine top heat dissipation pipe 8, it carries away the heat carried by the coolant, achieving wind-assisted heat dissipation. When the internal temperature of the enclosure drops below the second preset threshold, the control system controls the electronic air valve 19 to close, reducing the heat dissipation airflow and avoiding excessive heat dissipation that would waste energy. The humidity sensor module 17 monitors the humidity inside the inner heat dissipation port 12 in real time. When the humidity exceeds the set value, the control system controls the electronic air valve 19 to close, preventing external rainwater from falling into the enclosure through the horizontal air guide pipe 7.

[0030] The humidity sensor module 17 and the temperature sensor controller 18 work together to independently control the inner heat dissipation vents 12 at different locations, thereby enhancing heat dissipation at fixed locations and closing off single water accumulation locations to improve safety.

[0031] During use, part of the heat generated by the energy storage module 2 is absorbed by the liquid cooling circuit and transported to the serpentine top heat dissipation pipe 8, while the other part is carried away by the air cooling channel formed by the fan 41 and the horizontal guide pipe 7. The combined effect of liquid cooling and air cooling keeps the internal temperature of the enclosure uniform. The temperature sensor controller 18, the electronic air valve 19 and the humidity sensor module 17 work together to achieve adaptive adjustment of the internal temperature and humidity of the enclosure, ensuring that the energy storage system operates stably in a suitable temperature environment and extending the service life of the battery cells.

[0032] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
