Technical Field

[0001] The present invention belongs to the technical field of energy storage battery packs, and specifically relates to an energy storage battery pack for industrial and commercial use with efficient heat dissipation. Background Art

[0002] Energy storage battery packs for industrial and commercial use mainly play three core roles: First, cost reduction and efficiency improvement are achieved through peak-valley arbitrage. They charge during low electricity price periods and discharge during peak periods, significantly reducing the electricity cost of enterprises. Second, as an emergency power supply, they ensure production continuity and provide continuous power supply during power grid failures to avoid production interruption losses.

[0003] The invention patent with the publication number CN220324648U discloses an energy storage battery pack and an energy storage device. The key points of its technical solution are: It includes a square shell in the shape of a square tube. A plurality of evenly distributed plate-shaped batteries are arranged in the square shell. Two parallel concave and folded bottom plates are fixed below the square shell, and the concave and folded bottom plates support and fix the batteries. A braking member and a detection member are arranged on one side of each battery.

[0004] However, the above technologies often have the following defects: A large amount of heat is generated when the battery pack works. If it cannot be dissipated in time, many faults will be caused. For example, overheating of the battery will cause the evaporation of the electrolyte inside the battery, resulting in a decline in battery performance and a shortening of its lifespan. It may also cause the battery to bulge and short-circuit. In severe cases, it may even lead to thermal runaway, and then cause dangerous situations such as battery combustion and explosion, threatening the use safety. Therefore, the present invention provides an energy storage battery pack for industrial and commercial use with efficient heat dissipation. Summary of the Invention

[0025] In order to make the technical means, creative features, achieved objectives and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] Embodiment 1: As Figures 1 to 4 shown, a high-efficiency heat-dissipating industrial and commercial energy storage battery pack according to an embodiment of the present invention includes a housing 1, and a battery pack is arranged inside the housing 1; a group of first heat dissipation holes 2 are opened on one side of the housing 1, and a group of second heat dissipation holes 3 are opened on the side of the housing 1 away from the first heat dissipation holes 2; a connecting block 4 is fixedly connected to the side of the housing 1 close to the first heat dissipation holes 2, a hollow groove 5 is opened in the connecting block 4, and a first connection communicating with the first heat dissipation holes 2 is opened on the side of the connecting block 4 close to the housing 1; an air pump 6 for injecting gas into the hollow groove 5 is arranged at the top of the connecting block 4, and a temperature sensor 31 for starting the air pump 6 is arranged inside the housing 1; when the internal temperature of the housing 1 in the present application is too high, the temperature sensor 31 will sense it and start the air pump 6, so that the air pump 6 injects gas into the hollow groove 5. At this time, the gas will pass through the first connection hole 7 and the first heat dissipation holes 2, and then blow on the battery pack inside the housing 1, thereby efficiently dissipating heat from the battery pack and ensuring the stability of the battery pack during operation. When the temperature reaches a safe value, the temperature sensor 31 will turn off the air pump 6.

[0027] A connecting frame 8 is slidably connected inside the hollow groove 5. A filter screen 9 is fixedly connected to the inner wall of the connecting frame 8. A group of first springs 19 are fixedly connected to the top surface of the connecting frame 8. The top surface of the first springs 19 is fixedly connected to a connecting plate 10. The side wall of the connecting plate 10 is fixedly connected to the hollow groove 5. A driving component for driving the connecting frame 8 to vibrate is arranged inside the hollow groove 5; since the gas contains dust impurities, it is easy for the impurities to adhere to the battery pack when the gas directly blows on the battery pack, resulting in a reduction in the self-heat dissipation efficiency of the battery pack. At this time, the dust impurities in the gas can be filtered by the filter screen 9, and then blown onto the battery pack. At the same time, the driving component can be used to drive the connecting frame 8 to vibrate, thereby driving the filter screen 9 to vibrate to prevent the mesh holes of the filter screen 9 from being blocked.

[0028] A partition 11 is fixedly connected to the inner wall of the hollow groove 5. A group of round holes 12 are opened on the partition 11. The round holes 12 are located below the connecting frame 8; when the filter screen 9 in the present application vibrates, it is inevitable that dust impurities will fall off. At this time, the fallen impurities can be blocked by the partition 11 to reduce the impurities being carried by the gas onto the battery pack, and the gas can pass through the round holes 12.

[0029] The driving component includes a rotating shaft 13 rotatably connected to the top surface of the partition plate 11. A set of driving blades 14 are fixedly connected to the side wall of the rotating shaft 13. A magnet 15 magnetically attracted to the connecting frame 8 is fixedly connected to the top surface of the driving blade 14. In this application, when the gas is injected into the hollow groove 5, the gas will drive the driving blade 14 to rotate, so that the magnet 15 on the driving blade 14 intermittently passes by the connecting frame 8, thereby making the magnet 15 magnetically attract the connecting frame 8 intermittently. When the connecting frame 8 is magnetically attracted, it will move downward. When it is not magnetically attracted, the first spring 19 will pull the connecting frame 8 upward to reset, so that the connecting frame 8 shakes, so as to make the filter screen 9 shake.

[0030] A first sealing plate 16 is slidably connected to the inner wall of the hollow groove 5 close to the outer shell 1. A second connecting hole 17 corresponding to the first connecting hole 7 is opened on the first sealing plate 16. A moving component for driving the first sealing plate 16 to move is arranged in the hollow groove 5. When the air pump 6 in this application injects gas into the hollow groove 5, the moving component can be used to drive the first sealing plate 16 to move downward, so that the first connecting hole 7 and the second connecting hole 17 are aligned. At this time, the gas can be blown out from both the first connecting hole 7 and the second connecting hole 17, and then blown on the battery pack for heat dissipation, thereby improving the uniformity of the gas blowing and the heat dissipation effect on the battery pack. When the gas injection stops, the moving component can be used to reset the first sealing plate 16. At this time, the first connecting hole 7 and the second connecting hole 17 will be misaligned. At this time, the first sealing plate 16 can seal the first connecting hole 7 to prevent dust and impurities from passing through the first connecting hole 7, the second connecting hole 17 and the first heat dissipation hole 2 into the outer shell 1.

[0031] The moving component includes a sliding plate 18 hermetically and slidably connected to the inner wall of the hollow groove 5. The bottom surface of the first sealing plate 16 is fixedly connected to the sliding plate 18. A second spring 20 is fixedly connected to the bottom surface of the sliding plate 18. The bottom surface of the second spring 20 is fixedly connected to the inner wall of the hollow groove 5. An air outlet communicating with the hollow groove 5 is opened on the bottom surface of the connecting block 4. When the air pump 6 in this application injects gas into the hollow groove 5, the gas will push the sliding plate 18 downward, so that the sliding plate 18 drives the first sealing plate 16 to move downward, so that the first connecting hole 7 and the second connecting hole 17 are aligned, so that the gas can be blown from the first heat dissipation part to the battery pack.

[0032] Embodiment 2: As Figures 5 to 6As shown in the figure, compared with the first comparative example, another implementation manner of the present invention is: a hollow block 21 is fixedly connected to one side of the outer shell 1 close to the second heat dissipation hole 3. A first through hole 22 corresponding to the second heat dissipation hole 3 is opened on one side of the hollow block 21 close to the outer shell 1. A second through hole 23 is opened on the side of the hollow block 21 away from the first through hole 22. A second sealing plate 24 is slidably connected to the inner wall side of the hollow block 21 close to the outer shell 1. A guide hole 25 corresponding to the first through hole 22 is opened on the second sealing plate 24. A third spring 28 is fixedly connected between the bottom surface of the second sealing plate 24 and the inner wall of the hollow block 21. An electromagnet 26 magnetically attracted to the second sealing plate 24 is fixedly connected to the inner wall of the hollow block 21. When the battery pack in this application is not working, the second sealing plate 24 will seal the first through hole 22 to prevent dust and impurities from entering the outer shell 1 through the second heat dissipation hole 3. When the battery pack is working, the electromagnet 26 will be automatically activated, thereby attracting the second sealing plate 24 to move upward so that the guide hole 25 communicates with the first through hole 22. At this time, the heat inside the outer shell 1 can be normally dissipated at the second heat dissipation hole 3.

[0033] A hollow elastic block 27 is fixedly connected to the inner wall of the hollow block 21. The elastic block 27 includes the electromagnet 26, and red gas is stored in the elastic block 27. A fourth spring 29 is fixedly connected between the inner walls of the elastic block 27. A puncture cone 30 is fixedly connected to the top surface of the second sealing plate 24. A temperature sensor 31 in this application is set with a numerical value of the alarm temperature. When this temperature is reached, the magnetic force of the electromagnet 26 will increase, thereby driving the puncture cone 30 on the second sealing plate 24 to pierce the elastic block 27. At this time, the fourth spring 29 will pull the elastic block 27, so that the red gas in the elastic block 27 is quickly discharged and then dissipated through the second through hole 23 for alarm.

[0034] Working principle: When the temperature inside the outer shell 1 is too high, the temperature sensor 31 will sense it and start the air pump 6, so that the air pump 6 injects gas into the hollow groove 5. At this time, the gas will pass through the first connection hole 7 and the first heat dissipation hole 2, and then blow on the battery pack inside the outer shell 1, thereby efficiently dissipating heat from the battery pack and ensuring the stability of the battery pack during operation. When the temperature reaches the safe value, the temperature sensor 31 will turn off the air pump 6; the filter screen 9 filters dust and impurities in the gas, and then blows it onto the battery pack. At the same time, the driving assembly can be used to drive the connecting frame 8 to shake, thereby driving the filter screen 9 to shake to prevent the mesh holes of the filter screen 9 from being blocked; when the filter screen 9 shakes, dust and impurities will inevitably fall. At this time, the falling impurities can be blocked by the partition plate 11 to reduce the impurities being driven by the gas onto the battery pack. The gas can pass through the round hole 12.

[0035] When the gas is injected into the hollow groove 5 in this application, the gas will drive the driving blade 14 to rotate, so that the magnetic block 15 on the driving blade 14 intermittently passes by the connecting frame 8, thereby making the magnetic block 15 magnetically attract the connecting frame 8 intermittently. When the connecting frame 8 is magnetically attracted, it will move downward. When it is not magnetically attracted, the first spring 19 will pull the connecting frame 8 upward to reset, so that the connecting frame 8 shakes, so that the filter screen 9 shakes; when the air pump 6 in this application injects gas into the hollow groove 5, it can drive the first sealing plate 16 to move downward by means of the moving component, so that the first connection hole 7 and the second connection hole 17 are aligned. At this time, the gas can blow out from the first connection hole 7 and the second connection hole 17 at the same time, and then blow on the battery pack for heat dissipation, thereby improving the uniformity of the gas blowing and the heat dissipation effect on the battery pack. When the air injection stops, the first sealing plate 16 can be reset by means of the moving component. At this time, the first connection hole 7 and the second connection hole 17 are misaligned. At this time, the first sealing plate 16 can seal the first connection hole 7 to prevent dust and impurities from passing through the first connection hole 7, the second connection hole 17 and the first heat dissipation hole 2 into the housing 1; when the air pump 6 in this application injects gas into the hollow groove 5, the gas will push the slide plate 18 downward, so that the slide plate 18 drives the first sealing plate 16 downward, so that the first connection hole 7 and the second connection hole 17 are aligned, so that the gas can blow from the first heat dissipation place to the battery pack.
