Description

Technical Field

[0001] This invention belongs to the field of energy storage battery technology, specifically a high-efficiency heat dissipation industrial and commercial energy storage battery. Background Technology

[0002] Commercial and industrial energy storage battery packs play three main roles: First, they reduce costs and increase efficiency through peak-valley arbitrage, charging during off-peak hours and discharging during peak hours, significantly reducing the electricity costs for enterprises; second, they serve as emergency power sources to ensure production continuity, providing continuous power supply during grid failures and avoiding production interruption losses.

[0003] The invention patent with publication number CN220324648U discloses an energy storage battery pack and an energy storage device. The key technical points of the solution are: it includes a square shell in the shape of a square tube, in which a plurality of plate-shaped batteries are arranged evenly. Two parallel concave bottom plates are fixed at the bottom of the square shell, and the concave bottom plates support and fix the batteries. Each battery has a braking component and a detection component on one side.

[0004] However, the above technologies often have the following drawbacks: the battery pack generates a lot of heat when it is working. If it cannot be dissipated in time, it will cause many malfunctions. For example, overheating of the battery will cause the electrolyte inside the battery to evaporate, resulting in a decrease in battery performance and a shortened life. It may also cause the battery to bulge, short circuit, and in severe cases, even thermal runaway, which may lead to dangerous situations such as battery combustion and explosion, threatening the safety of use. Therefore, the present invention provides a commercial and industrial energy storage battery pack with high-efficiency heat dissipation. Summary of the Invention

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] Example 1: As Figures 1 to 4 As shown in the figure, an efficient heat dissipation commercial and industrial energy storage battery pack according to an embodiment of the present invention includes a housing 1, in which a battery pack is disposed; a first heat dissipation hole 2 is provided on one side of the housing 1, and a second heat dissipation hole 3 is provided on the side of the housing 1 away from the first heat dissipation hole 2; a connecting block 4 is fixedly connected to the side of the housing 1 near the first heat dissipation hole 2, a hollow groove 5 is provided in the connecting block 4, and a first connection communicating with the first heat dissipation hole 2 is provided on the side of the connecting block 4 near the housing 1; the top of the connecting block 4 is provided with An air pump 6 is provided to inject air into the hollow slot 5. A temperature sensor 31 for activating the air pump 6 is provided inside the outer casing 1. When the internal temperature of the outer casing 1 is too high, the temperature sensor 31 will detect it and activate the air pump 6, which will inject gas into the hollow slot 5. At this time, the gas will pass through the first connecting hole 7 and the first heat dissipation hole 2, and then blow onto the battery pack inside the outer casing 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 shut down 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 set of first springs 19 is fixedly connected to the top surface of the connecting frame 8. A connecting plate 10 is fixedly connected to the top surface of the first springs 19. 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 provided inside the hollow groove 5. Since the gas contains dust and impurities, if the gas is blown directly onto the battery pack, the impurities are easily attached to the battery pack, thereby reducing the heat dissipation efficiency of the battery pack itself. At this time, the dust and impurities in the gas can be filtered by the filter screen 9 before being blown onto the battery pack. At the same time, the driving component can be used to drive the connecting frame 8 to vibrate, thereby causing the filter screen 9 to vibrate, so as to prevent the mesh of the filter screen 9 from becoming clogged.

[0028] A partition 11 is fixedly connected to the inner wall of the hollow groove 5. A set of round holes 12 are provided on the partition 11, and the round holes 12 are located below the connecting frame 8. When the filter screen 9 in this application is shaken, dust and impurities will inevitably fall off. At this time, the falling impurities can be blocked by the partition 11 to reduce the impurities being carried to the battery pack by the gas. The gas can pass through the round holes 12.

[0029] The drive assembly includes a rotating shaft 13 rotatably connected to the top surface of the partition 11. A set of drive blades 14 are fixedly connected to the side wall of the rotating shaft 13. A magnetic block 15 that magnetically attracts the connecting frame 8 is fixedly connected to the top surface of the drive blade 14. In this application, when gas is injected into the hollow groove 5, the gas will drive the drive blades 14 to rotate, causing the magnetic block 15 on the drive blades 14 to intermittently pass through the connecting frame 8, thereby causing the magnetic block 15 to intermittently attract the connecting frame 8. 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, thereby causing the connecting frame 8 to shake, so that the filter screen 9 shakes.

[0030] A first sealing plate 16 is slidably connected to the inner wall of the hollow groove 5 near the outer shell 1. The first sealing plate 16 has a second connecting hole 17 corresponding to the first connecting hole 7. A moving component for driving the first sealing plate 16 to move is provided inside the hollow groove 5. When the air pump 6 of this application injects gas into the hollow groove 5, it can drive the first sealing plate 16 to move downward with the help of the moving component, thereby aligning the first connecting hole 7 and the second connecting hole 17. At this time, the gas can be blown out from the first connecting hole 7 and the second connecting hole 17 at the same time, and then blown onto the battery pack for heat dissipation, thereby improving the uniformity of gas blowing and improving the heat dissipation effect on the battery pack. When the gas injection stops, the first sealing plate 16 can be reset with the help of the moving component. 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 entering the outer shell 1 through the first connecting hole 7, the second connecting hole 17 and the first heat dissipation hole 2.

[0031] The moving component includes a sliding plate 18 that is slidably and sealingly 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. The bottom surface of the connecting block 4 is provided with an air outlet that communicates with the hollow groove 5. When the air pump 6 of this application injects air into the hollow groove 5, the gas will push the sliding plate 18 downward, causing the sliding plate 18 to drive the first sealing plate 16 downward, thereby aligning the first connecting hole 7 and the second connecting hole 17 so that the gas can be blown from the first heat dissipation point to the battery pack.

[0032] Example 2: Figures 5 to 6As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a hollow block 21 is fixedly connected to the side of the outer shell 1 near the second heat dissipation hole 3. A first through hole 22 corresponding to the second heat dissipation hole 3 is opened on the side of the hollow block 21 near 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 side of the hollow block 21 near the inner wall of the outer shell 1. A guide hole 25 corresponding to the first through hole 22 is opened on the second sealing plate 24. The bottom surface of the second sealing plate 24 is... A third spring 28 is fixedly connected between the inner walls of the hollow block 21, and an electromagnet 26 that magnetically attracts 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 casing 1 from 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 can connect with the first through hole 22. At this time, the heat inside the outer casing 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 is included on the electromagnet 26 and contains red gas. A fourth spring 29 is fixedly connected between the inner walls of the elastic block 27. A piercing cone 30 is fixedly connected to the top surface of the second sealing plate 24. The temperature sensor 31 of this application is set with an alarm temperature value. When the temperature is reached, the magnetic force of the electromagnet 26 will increase, thereby driving the piercing 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 will be quickly discharged and then emitted from the second through hole 23 to trigger an alarm.

[0034] Working principle: When the internal temperature of the outer casing 1 is too high, the temperature sensor 31 will detect it and start the air pump 6, which will inject gas into the hollow groove 5. The gas will then pass through the first connecting hole 7 and the first heat dissipation hole 2, and then be blown onto the battery pack inside the outer casing 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 shut off the air pump 6. Dust and impurities in the gas are filtered through the filter screen 9 before being blown onto the battery pack. At the same time, the connecting frame 8 can be driven by the drive component to shake, thereby causing the filter screen 9 to shake, preventing the mesh of the filter screen 9 from becoming clogged. Dust and impurities will inevitably fall off the filter screen 9 during shaking. These impurities can be blocked by the partition 11 to reduce the impurities being carried onto the battery pack by the gas. The gas can pass through the round hole 12.

[0035] In this application, when gas is injected into the hollow groove 5, the gas drives the drive blade 14 to rotate, causing the magnetic block 15 on the drive blade 14 to intermittently pass through the connecting frame 8, thereby intermittently attracting the connecting frame 8. When the connecting frame 8 is attracted, it moves downward; when it is not attracted, the first spring 19 pulls the connecting frame 8 upward to reset it, causing the connecting frame 8 to vibrate, which in turn causes the filter screen 9 to vibrate. In this application, when the air pump 6 injects gas into the hollow groove 5, it can drive the first sealing plate 16 downward with the help of the moving component, thereby aligning the first connecting hole 7 and the second connecting hole 17. At this time, the gas can be blown out from the first connecting hole 7 and the second connecting hole 17 simultaneously, and then blown onto the battery. The gas is blown out evenly to improve the heat dissipation effect on the battery pack. When the gas injection stops, the first sealing plate 16 can be reset by the moving component. At this time, the first connecting hole 7 and the second connecting hole 17 will be misaligned. The first sealing plate 16 can seal the first connecting hole 7 to prevent dust and impurities from entering the outer casing 1 through the first connecting hole 7, the second connecting hole 17 and the first heat dissipation hole 2. When the air pump 6 of this application injects gas into the hollow groove 5, the gas will push the slide plate 18 to move downward, so that the slide plate 18 drives the first sealing plate 16 to move downward, thereby aligning the first connecting hole 7 and the second connecting hole 17 so that the gas can be blown from the first heat dissipation point to the battery pack.
