Description

Technical Field

[0001] The present invention relates to a battery pack heat dissipation technology, and in particular to an energy storage container system with inert gas circulation cooling. Background Art

[0002] With the rapid development of the new energy industry, energy storage container systems, with their high integration and convenience, have become core facilities for power supply in the automotive, shipbuilding, and aircraft industries. However, existing energy storage container systems still face significant technical bottlenecks in heat dissipation and safety protection.

[0003] Traditional energy storage container heat dissipation technology mainly uses air cooling or liquid cooling. The air cooling system relies on air convection to dissipate heat. In high-density battery integration scenarios, it is prone to problems such as uneven heat dissipation and low efficiency, which can lead to local overheating of the battery, accelerated battery aging and reduced service life. Although the liquid cooling system can achieve efficient heat dissipation, there is a risk of coolant leakage. Once a leak occurs, it may cause a battery short circuit or equipment corrosion, seriously threatening the safe operation of the system. In addition, neither air cooling nor liquid cooling can effectively deal with the problem of battery thermal runaway. When the battery is short-circuited, overcharged or over-discharged, the high temperature, flammable gas release and flame spread caused by thermal runaway can easily lead to a chain reaction, causing a large-scale explosion or fire accident. Existing technologies lack effective means to quickly isolate and actively suppress thermal runaway.

[0004] At the same time, with the increasing adoption of energy storage systems in high-risk sectors like transportation, the requirements for their safety and reliability are becoming increasingly stringent. Traditional protection technologies can only passively delay the progression of thermal runaway, but are unable to eliminate combustion conditions at the root and mitigate the hazards of accidents. Therefore, developing an energy storage container system that combines efficient heat dissipation with active thermal runaway protection is a key requirement for addressing the pain points of existing technologies and promoting the safe development of the energy storage industry.

[0018] Furthermore, a soundproof cover is provided on the outside of the centrifugal fan.

[0019] Compared with the prior art, the energy storage container system with inert gas circulation cooling provided by the present invention has the following beneficial effects:

[0020] (1) The energy storage container system adopts a combination of an inert gas air-cooled circulation mechanism and a battery pack external cooling mechanism, which greatly improves the heat dissipation effect of the battery. The centrifugal fan sends the inert gas into the heat exchanger, which is cooled by the water cooler and then transported to the battery pack through multi-stage pipes. The cooled inert gas flows in the pack to take away the heat, and then re-enters the centrifugal fan and heat exchanger through the return pipe to form a circulating cooling. Compared with traditional heat dissipation methods, this circulating cooling can enable the inert gas to fully cool the battery pack, avoiding performance degradation or shortened life due to battery overheating, ensuring that the battery always maintains a stable and efficient operating state in applications in industries such as automobiles, ships and aircraft, and meets the heat dissipation requirements under high-load and long-term use scenarios.

[0021] (2) The system provides dual protection for battery safety by virtue of the chemical properties of inert gases and the thermal runaway protection mechanism. On the one hand, inert gases (such as nitrogen, argon, and carbon dioxide) are chemically stable and do not participate in combustion reactions. When the battery pack experiences thermal runaway, they can effectively dilute the oxygen concentration, destroy the combustion conditions, and suppress the occurrence of combustion or even explosion. On the other hand, the thermal runaway protection mechanism, through the coordinated work of components such as the three-way electric valve and the two-way electric valve, can quickly isolate the faulty battery pack at the moment of battery thermal runaway, accurately control the delivery path of the inert gas, quickly remove the flammable gas generated by thermal runaway, effectively suppress the spread of thermal runaway, and greatly improve the control efficiency of thermal runaway of the battery pack. In addition, compared with the liquid cooling system, inert gas cooling does not have the risk of liquid leakage causing short circuit or corrosion, which ensures the safety of battery use from multiple dimensions and builds a solid safety line for the application of energy storage containers in various complex environments.

[0022] (3) When the battery pack experiences thermal runaway, the drive motor can quickly drive the transmission plate to locate the gap of the faulty battery pack, push the rubber liquid bag to stretch, and make the fireproof liquid cooling roll bag fit tightly to the top and bottom of the battery pack. The cooling water flows in through the water inlet pipe and is discharged through the water outlet pipe. The circulating flow takes away the heat from the surface of the battery pack, achieving efficient cooling. At the same time, the bulging fireproof liquid cooling roll bag forms a physical isolation layer, blocking the high temperature and flame generated by thermal runaway and preventing damage to adjacent battery packs. This mechanism cooperates with the inert gas circulation system to provide synergistic protection from cooling and physical isolation, effectively suppressing the spread of thermal runaway, reducing the risk of accidents, and significantly improving the safety and reliability of energy storage containers under complex working conditions.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] See also Figures 1 to 6 As shown, an inert gas circulation cooling energy storage container system includes:

[0036] Box body 1, a mounting frame 2 fixed inside the box body 1, a battery pack 3 fixedly connected to the mounting frame 2, a mounting frame 4 fixedly connected to one side of the box body 1, a dustproof net fixedly connected to the mounting frame 4, and a soundproof cover provided outside the centrifugal fan 11;

[0037] An inert gas air-cooling circulation mechanism is provided in the mounting frame 4, and the inert gas air-cooling circulation mechanism is used to circulate air cooling to the battery pack 3;

[0038] The box body 1 is provided with a battery pack external cooling mechanism, which is used to perform wrap-around cooling on the outside of the battery pack.

[0039] By connecting the battery pack 3 in the box 1 to the inert gas air cooling circulation mechanism on the box 1, the air in the box 1 is then extracted and the box 1 is filled with inert gas, so that multiple battery packs 3 are in the inert gas. The cooled inert gas is introduced into the battery pack 3 in the box 1 through the inert gas air cooling mechanism, and the inert gas after heat dissipation is circulated and cooled, so that the battery pack 3 is fully cooled and heat dissipated, thereby improving the heat dissipation effect of the battery. At the same time, the inert gas (which can also be nitrogen or carbon dioxide) has stable chemical properties and does not participate in the combustion reaction. When the battery pack 3 experiences thermal runaway, the inert gas can dilute the oxygen concentration and reduce the combustion conditions in the three elements of combustion (combustibles, combustion-supporting materials, and ignition sources), thereby effectively suppressing the occurrence of combustion or even explosion. At the same time, compared with the liquid cooling system, the inert gas cooling does not need to worry about short circuits or corrosion problems caused by liquid leakage, further improving the safety of battery heat dissipation, and realizing that the battery pack can be safely used in industries such as automobiles, ships, and aircraft.

[0040] The inert gas air-cooling circulation mechanism includes a centrifugal fan 11 fixedly connected to the box body 1, the output end of the centrifugal fan 11 is fixedly connected to the heat exchanger 12 through a pipeline, the output end of the heat exchanger 12 is fixedly connected to the first main pipe 13, the heat exchanger 12 is fixedly connected to the water cooler 14 through a pipeline, the upper part of the first main pipe 13 is fixedly connected to a first diode 15, one end of the first diode 15 is fixedly connected to a plurality of first tertiary tubes 16 through a pipeline, the first tertiary tube 16 is connected to the air inlet of the Pack battery pack 3, the output port of the Pack battery pack 3 is fixedly connected to a second tertiary tube 17, one end of the second tertiary tube 17 is fixedly connected to a second diode 18, and one end of the second diode 18 is fixedly connected to a second main pipe 19 fixedly connected to the centrifugal fan 11;

[0041] The first main pipe 13 is provided with a thermal runaway protection mechanism, which is used to protect the battery pack 3 from thermal runaway.

[0042] The inert gas is fed into the heat exchanger 12 through the centrifugal fan 11. The heat exchanger 12 cools the inert gas entering the heat exchanger 12 through the cooperation of the water cooler 14. The cooled gas is then passed into each first and second tubes 15 through the first main pipe 13. The first and second tubes 15 pass the gas into multiple first tertiary tubes 16. The first tertiary tubes 16 then supply cooled inert gas into the Pack battery pack 3. The cooled inert gas then flows in the Pack battery pack 3 to cool the Pack battery pack 3. The inert gas then passes through the second tertiary tube 17 into the second secondary tube 18. The second secondary tube 18 passes the refluxed inert gas into the centrifugal fan 11 through the second main pipe 19. The centrifugal fan 11 passes the inert gas into the heat exchanger 12, thereby realizing inert gas circulation cooling of multiple Pack battery packs 3 in the energy storage container.

[0043] Example 2

[0044] Based on Example 1, please refer to Figure 2 、 Figure 3 and Figure 5 As shown, the thermal runaway protection mechanism includes a three-way electric valve 21 fixedly connected to the first main pipe 13, the three-way electric valve 21 is fixedly connected to the inert gas bottle 22 fixedly connected to the box body 1 through a pipeline, the second tertiary pipe 17 is fixedly connected to the exhaust pipe 24, the exhaust pipe 24 is provided with a first two-way electric valve 23, the exhaust pipe 24 is provided with a one-way valve, one end of the exhaust pipe 24 is fixedly connected to the outlet pipe fixedly connected to the box body 1, the first two-stage pipe 15 is provided with a second two-way electric valve 25, and the first tertiary pipe 16 is provided with a third two-way electric valve 26.

[0045] When a certain battery pack 3 experiences thermal runaway, the other battery packs 3 are quickly closed, and the second two-way electric valves 25 on the other first and second diodes 15 are closed at the same time. Only the second two-way electric valve 25 on the first and second diodes 15 corresponding to the battery pack 3 experiencing thermal runaway is opened, and the third two-way electric valve 26 on the first and third diodes 16 corresponding to the other battery packs 3 on the first and second diodes 15 are closed at the same time. At this time, the three-way electric valve 21 is opened to allow the inert gas in the inert gas bottle 22 to be transported to the first main pipe 13 through the pipeline. At this time, the third two-way electric valve 26 on the first and third diodes 16 corresponding to the other battery packs 3 on the first and second diodes 15 is opened. A main pipe 13 fills the corresponding thermal runaway battery pack 3 with inert gas through the first diode 15 and the first tertiary tube 16, taking away the heat in the battery pack 3 and also taking away the combustible gases such as H2, CO, C2H4 generated in the battery pack 3 during thermal runaway. At this time, the first two-way electric valve 23 on the exhaust pipe 24 is opened, and then the inert gas is passed into the outlet pipe through the exhaust pipe 24 and then discharged through the outlet pipe, effectively suppressing the aggravation of thermal runaway, thereby effectively improving the control efficiency of thermal runaway of the battery pack 3.

[0046] Example 3

[0047] Based on Example 2, please refer to Figure 4 、 Figure 6 and Figure 7 As shown, the external cooling mechanism of the battery pack includes two transmission plates 31 that are slidably connected to the box body 1, a plurality of connection frames 32 are fixedly connected to the transmission plates 31, a fireproof liquid cooling roll bag 33 is fixedly connected to the connection frame 32, the outer surface of the fireproof liquid cooling roll bag 33 is fixedly connected to a water inlet pipe 34 and a water outlet pipe 35, and both the water inlet pipe 34 and the water outlet pipe 35 are fixedly connected to an electromagnetic electric valve, one end of the water inlet pipe 34 is fixedly connected to a first water supply pipe 36 that is fixedly connected to the transmission plate 31 through a pipe, the outer surface of the first water supply pipe 36 is fixedly connected to a second water supply pipe 37 that is fixedly connected to the box body 1 through a hose and a pipe, one end of the water outlet pipe 35 is fixedly connected to a first drain pipe 38 that is fixedly connected to the connection frame 32 through a pipe, and the outer surface of the first drain pipe 38 is fixedly connected to a second drain pipe 39 that is fixedly connected to the box body 1 through a hose and a pipe;

[0048] A pushing mechanism is fixedly connected in the connecting frame 32, and the pushing mechanism is used to push the fireproof liquid cooling roll bag 33 to unfold. A driving mechanism connected to the box body 1 is provided on the transmission plate 31, and the driving mechanism is used to drive the transmission plate 31 to move.

[0049] The pushing mechanism includes a pushing rubber sac 41 fixedly connected to the connecting frame 32 . The outer surface of the pushing rubber sac 41 is fixedly connected to a connecting pipe 42 fixedly connected to the first water supply pipe 36 . The connecting pipe 42 is provided with an electromagnetic electric valve.

[0050] The driving mechanism includes a driving motor 51 fixedly connected to the box body 1. The driving motor 51 is controlled by a PLC programming program, and the driving motor 51 can be controlled to rotate forward and reverse and at an angle. The output end of the driving motor 51 is fixedly connected to a threaded rod 52 rotatably connected to the box body 1 through a coupling. The threaded rod 52 is threadedly connected to the transmission plate 31. A guide rod fixedly connected to the box body 1 is slidably connected to the transmission plate 31. The threaded rod 52 is driven to rotate by the driving motor 51, and the threaded rod 52 drives the transmission plate 31 to move.

[0051] When a certain Pack battery pack 3 has thermal runaway, the transmission plate 31 is driven by the driving mechanism to move to the gap where multiple Pack battery packs 3 are installed, and then water is pumped into the second water supply pipe 37 (heat dissipation media such as liquid nitrogen, perfluorohexanone and aerosol can also be pumped in), and then the electromagnetic electric valve on the connecting pipe 42 on the corresponding upper and lower connecting frames 32 is opened, and the second water supply pipe 37 supplies water to the first water supply pipe 36 through a hose, and the first water supply pipe 36 passes water into the connecting pipe 42, and then the water enters the pushing rubber liquid bag 41 through the connecting pipe 42. At this time, the pushing rubber liquid bag 41 begins to stretch and push the fireproof liquid cooling roll bag 33 to move, so that the fireproof liquid cooling roll bag 33 is unfolded along the gap between the Pack battery packs 3, and then the fireproof liquid cooling roll bag 33 is opened to enter Through the electromagnetic electric valve on the water pipe 34, water begins to enter the fireproof liquid cooling roll bag 33, causing the fireproof liquid cooling roll bag 33 to swell, so that the upper and lower fireproof liquid cooling roll bags 33 are respectively attached to the top and bottom of the thermal runaway Pack battery pack 3, and then the electromagnetic electric valve on the water outlet pipe 35 is opened, and then the water outlet pipe 35 is discharged through the first drain pipe 38, the pipe, the hose and the second drain pipe 39. While draining, the second water supply pipe 37 continuously supplies water to realize the continuous circulation of the cooling water in the fireproof liquid cooling roll bag 33, driving the heat on the surface of the Pack battery pack 3, and at the same time isolating the Pack battery pack 3 above and below the thermal runaway, effectively preventing the high temperature heat generated by the thermal runaway from causing damage to other batteries, and further improving the safety of the Pack battery pack 3 in the energy storage container.

[0052] Working principle: When in use, the battery pack 3 in the box 1 is connected to the inert gas air cooling circulation mechanism on the box 1, and then the air in the box 1 is extracted and filled with inert gas, so that multiple battery packs 3 are in the inert gas. The cooled inert gas is passed through the inert gas air cooling mechanism to the battery pack 3 in the box 1, and the inert gas after heat dissipation is circulated and cooled, so that the battery pack 3 is fully cooled and dissipated, improving the heat dissipation effect of the battery. At the same time, the inert gas (which can also be nitrogen or carbon dioxide) has stable chemical properties and does not participate in the combustion reaction. When the battery pack 3 experiences thermal runaway, the inert gas can dilute the oxygen concentration and reduce the combustion conditions in the three elements of combustion (combustibles, combustion-supporting materials, and ignition sources), thereby effectively suppressing the occurrence of combustion or even explosion. At the same time, compared with the liquid cooling system, the inert gas cooling does not need to worry about short circuits or corrosion problems caused by liquid leakage, further improving the safety of battery heat dissipation, and realizing the safe use of battery packs in industries such as automobiles, ships and aircraft.

[0053] When a certain Pack battery pack 3 has thermal runaway, the transmission plate 31 is driven by the driving mechanism to move to the gap where multiple Pack battery packs 3 are installed, and then water is pumped into the second water supply pipe 37 (heat dissipation media such as liquid nitrogen, perfluorohexanone and aerosol can also be pumped in), and then the electromagnetic electric valve on the connecting pipe 42 on the corresponding upper and lower connecting frames 32 is opened, and the second water supply pipe 37 supplies water to the first water supply pipe 36 through a hose, and the first water supply pipe 36 passes water into the connecting pipe 42, and then the water enters the pushing rubber liquid bag 41 through the connecting pipe 42. At this time, the pushing rubber liquid bag 41 begins to stretch and push the fireproof liquid cooling roll bag 33 to move, so that the fireproof liquid cooling roll bag 33 is unfolded along the gap between the Pack battery packs 3, and then the fireproof liquid cooling roll bag 33 is opened to enter Through the electromagnetic electric valve on the water pipe 34, water begins to enter the fireproof liquid cooling roll bag 33, causing the fireproof liquid cooling roll bag 33 to swell, so that the upper and lower fireproof liquid cooling roll bags 33 are respectively attached to the top and bottom of the thermal runaway Pack battery pack 3, and then the electromagnetic electric valve on the water outlet pipe 35 is opened, and then the water outlet pipe 35 is discharged through the first drain pipe 38, the pipe, the hose and the second drain pipe 39. While draining, the second water supply pipe 37 continuously supplies water to realize the continuous circulation of the cooling water in the fireproof liquid cooling roll bag 33, driving the heat on the surface of the Pack battery pack 3, and at the same time isolating the Pack battery pack 3 above and below the thermal runaway, effectively preventing the high temperature heat generated by the thermal runaway from causing damage to other batteries, and further improving the safety of the Pack battery pack 3 in the energy storage container.
