A lithium battery device for rapid heat dissipation and cooling

Abstract

This invention relates to the field of lithium battery cooling technology, specifically disclosing a lithium battery storage device capable of rapid heat dissipation and cooling. The device includes a housing with a top cover. A battery pack is housed inside the housing, with its upper and lower ends respectively fixedly connected to the lower surface of the top cover and the upper bottom surface of the housing. Heat dissipation fins are fixedly connected to the outer surface of the battery pack. Because a closing disc is located on the outer side of the air inlet duct, and the middle of the closing disc is threadedly connected to a connecting shaft, when the fan rotates, it first magnetically drives the connecting shaft to rotate, causing the closing disc to move along a limiting rod towards the connecting frame, opening the air inlet duct. When the closing disc can no longer move along the limiting rod, the connecting shaft stops rotating, while the fan continues to rotate. This achieves initial closure of the air inlet duct via the closing disc, preventing the housing from remaining open when the battery is not in operation, thus avoiding the entry of insects and dust into the housing.

Description

Technical Field

[0001] This invention relates to the field of lithium battery cooling technology, specifically to an energy storage lithium battery device capable of rapid heat dissipation and cooling. Background Technology

[0002] In the field of energy storage lithium battery technology, rapid heat dissipation and cooling lithium battery devices achieve efficient heat dissipation and protection of battery packs through the coordinated design of the outer casing, heat dissipation mechanism, and reinforcement mechanism. This device integrates dynamic heat dissipation and sealing protection through a fan-driven air intake system, an automatic opening and closing structure of the closing disc, and a linkage mechanism between the expansion bladder and the elastic telescopic rod. Its core lies in the intelligent opening and closing of the heat dissipation channel through pneumatic transmission, while simultaneously using heat dissipation fins and corrugated plates to improve heat dissipation efficiency. It is suitable for temperature control and safety protection of lithium batteries in high-power energy storage scenarios.

[0003] Traditional heat dissipation devices for energy storage lithium batteries have significant shortcomings. In terms of heat dissipation efficiency, traditional equipment often uses fixed ventilation structures, which cannot automatically adjust the airflow according to the battery's operating status. This results in inadequate heat dissipation under high loads and energy waste under low loads. Furthermore, dust easily clogs the air ducts during long-term operation, further reducing heat dissipation effectiveness. Their protective performance is weak; open ventilation holes easily introduce insects and dust, affecting the cleanliness of the battery's interior, and the lack of a dynamic sealing mechanism allows moisture intrusion, potentially causing short circuits. Structural stability is poor; traditional devices use a single method to fix the battery pack, which is prone to displacement under vibration, leading to poor contact of the heat dissipation fins or loosening of internal wiring. In addition, traditional equipment cannot achieve intelligent switching between heat dissipation and sealing, requiring manual intervention to open and close the heat dissipation channels. This cumbersome operation cannot adapt to real-time heat dissipation needs, limiting the reliability of energy storage lithium batteries in outdoor and complex environments. Summary of the Invention

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a lithium battery device for rapid heat dissipation and cooling, comprising a housing, a top cover on the top of the housing, a battery pack inside the housing, and further comprising: a heat dissipation mechanism fixedly mounted on the housing; and a reinforcement mechanism also fixedly mounted on the housing; wherein the upper and lower ends of the battery pack are respectively fixedly engaged with the lower surface of the top cover and the upper bottom surface of the housing, the battery pack is inverted, and heat dissipation fins are fixedly connected to the outer surface of the battery pack.

[0008] According to one embodiment of the present invention, the heat dissipation mechanism includes a heat dissipation plate, which is symmetrically and fixedly embedded in the outer surfaces of both sides of the outer casing. The heat dissipation plate has a pre-drilled through hole, and air inlet pipes are symmetrically and fixedly connected to the outer surfaces of both sides of the heat dissipation plate. A fan is rotatably connected to the inside of the air inlet pipes via a connecting rod.

[0009] According to one embodiment of the present invention, a limiting rod is fixedly connected to the surface of the end of the air inlet pipe away from the outer casing. Three limiting rods are fixedly spaced around the central axis of the air inlet pipe. A connecting frame is fixedly connected to the end of the limiting rod away from the air inlet pipe. A connecting shaft is rotatably connected through the central axis of the connecting frame. The connecting shaft is a threaded shaft. The end of the connecting shaft away from the connecting frame is rotatably connected to the fan shaft. The end of the connecting shaft near the fan shaft is magnetic.

[0010] According to one embodiment of the present invention, the outer surface of the connecting shaft is threadedly connected to a closed disc, the edge of which is slidably sleeved on the outer surface of the limiting rod, wherein the diameter of the closed disc is the same as the outer diameter of the air inlet pipe.

[0011] According to one embodiment of the present invention, the reinforcing mechanism includes a compression bladder, which is fixedly connected to the outer surface of the closed disc. The side of the compression bladder away from the closed disc is fixedly connected to the inner surface of the connecting frame. An elastic telescopic rod is fixedly connected to the lower edge of the top cover. The elastic telescopic rod is fixedly connected to the upper surface of the top edge of the outer shell. The internal cavity of the elastic telescopic rod is connected to the internal cavity of the compression bladder through a hose.

[0012] According to one embodiment of the present invention, mounting grooves are symmetrically formed on the inner surfaces of the top two sides of the outer shell, an expansion bladder is fixedly embedded inside the mounting groove, the internal cavity of the expansion bladder is connected to the internal cavity of the compression bladder through a hose, and a plug-in block is fixedly connected to the outer surface of the expansion bladder, the plug-in block is slidably inserted into the mounting groove.

[0013] According to one embodiment of the present invention, symmetrical grooves are provided in the two side walls of the outer casing. The grooves are located on the outer side of the heat sink plate. The two ends of the grooves are symmetrically rotatably connected to mounting rods. The mounting rods are threaded rods. The mounting rods are arranged in pairs as a group. A movable strip is threadedly connected to the mounting rods in the same group. A corrugated plate is fixedly connected to the upper surface of the movable strip. The corrugated plate is located on the outer side of the heat sink plate.

[0014] According to one embodiment of the present invention, a transmission belt is rotatably connected to the top outer surface of the mounting rod, and a drive rod is rotatably connected to the end of the transmission belt away from the mounting rod. The drive rod is rotatably connected through the top outer surface of the housing.

[0015] According to one embodiment of the present invention, an elastic telescopic plate is fixedly embedded at the bottom of the slide groove, the elastic telescopic plate is located directly below the moving strip, auxiliary grooves are symmetrically opened on both sides of the slide groove, the auxiliary grooves are located in the wall of the outer shell, an auxiliary bladder is fixedly connected inside the auxiliary groove, the internal cavity of the auxiliary bladder communicates with the internal cavity of the elastic telescopic plate, a sealing strip is fixedly connected to the outer surface of the auxiliary bladder, the sealing strip is slidably connected in the auxiliary groove, and the end of the sealing strip away from the auxiliary bladder is directly opposite to the outer surfaces of both sides of the corrugated plate. Under normal conditions, the battery pack is placed inside the outer shell, and the heat generated by the battery pack during operation is dissipated by the heat dissipation plate on the outer shell. In addition, the heat dissipation fins on the battery pack enable the heat generated during operation to be dissipated quickly, thereby improving the working stability of the battery pack. At the same time as the battery pack is working, the fan is started by electricity and begins to rotate. The rotation of the fan draws cold air from the outside and injects it into the outer shell, and the hot air inside the outer shell is discharged through the heat dissipation plate, thereby greatly improving the airflow effect inside the outer shell, and thus greatly improving the heat dissipation effect of the battery pack during operation.

[0016] (III) Beneficial Effects

[0017] This invention provides an energy storage lithium battery device capable of rapid heat dissipation and cooling. It offers the following advantages:

[0018] (i) The energy storage lithium battery device that can quickly dissipate heat and cool down has a closed disc on the outside of the air inlet pipe, and the middle of the closed disc is connected to the connecting shaft by a thread. When the fan rotates, it will first drive the connecting shaft to rotate through magnetism, causing the closed disc to move along the limit rod to the side of the connecting frame, opening the air inlet pipe. When the closed disc can no longer move along the limit rod, the connecting shaft stops rotating, while the fan continues to rotate. Thus, the air inlet pipe is initially closed by the closed disc, avoiding the problem of insects and dust entering the inside of the casing when the battery is not working because the inside of the casing is always open.

[0019] (II) The energy storage lithium battery device, which can quickly dissipate heat and cool down, compresses the compression bladder on its outer surface when the closed disc moves towards the connecting frame. The connecting shaft and the fan shaft are connected by a strong magnet, meaning that initially the connecting shaft will continuously rotate, compressing the compression bladder through the closed disc. This causes the compression bladder to transfer its internal air pressure to the elastic telescopic rod, which expands upwards, ultimately lifting the top cover upwards. At this time, the air inlet pipe is also opened, thus achieving simultaneous opening of the top cover when the fan opens the air inlet pipe to draw air into the outer casing, significantly improving the cooling performance of the battery pack. To improve heat dissipation and maintain the stability of the battery pack, the top cover moves upward, simultaneously driving the drive rod to rotate via threads. The rotation of the drive rod drives the transmission belt at its bottom to rotate, which in turn drives the mounting rod connected to the transmission belt to rotate. This causes the moving bar on the mounting rod to move upward within the slide groove, thus compressing the corrugated plate and causing it to contract. This allows the heat sink to connect to the outside environment simultaneously when the air intake duct is working. In conjunction with the closing disc and top cover, the side and top surfaces of the outer casing are fully opened to assist in heat dissipation when the fan is running, significantly improving the heat dissipation effect on the battery pack.

[0020] (III) This energy storage lithium battery device, capable of rapid heat dissipation and cooling, after the battery pack finishes working, the fan reverses to drive the closing disc to seal the air inlet pipe. Simultaneously, it causes the top cover to re-close the top of the outer casing, and further causes the corrugated plate to expand and seal the heat dissipation plate. This achieves complete sealing of the internal cavity of the outer casing after the battery pack finishes working, preventing the internal cavity of the outer casing from being connected to the outside for extended periods, thus avoiding potential safety hazards to the battery pack. When the compression bladder is compressed, its internal air pressure is transferred to the expansion bladder, causing it to expand. This pushes the insertion block outward along the mounting groove and ultimately inserts it between the heat dissipation fins on the battery pack. This allows the insertion block to automatically engage with the heat dissipation fins when the top cover is opened, thereby securing the top of the battery pack. The connection is fixed to prevent the battery pack from shaking inside the casing due to vibration after the top of the battery pack is opened, which could affect the safety of the battery pack. At the same time, when the moving strip moves down, it will eventually squeeze the elastic telescopic plate, causing the elastic compression plate to contract and send the internal air pressure to the auxiliary bladder in the auxiliary groove. This causes the auxiliary bladder to expand outward, which in turn pushes the sealing strip to move outward of the auxiliary groove. Finally, the sealing strip is clamped on both ends of the flattened corrugated plate. This achieves the effect of sealing the heat dissipation plate with the corrugated plate while squeezing and sealing the sides of the corrugated plate. This prevents moisture from entering the casing through the sides of the corrugated plate and affecting the safety of the battery pack. It ensures heat dissipation for the battery pack and also maximizes its safety when the battery pack is not in use. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] First embodiment: as follows Figures 1 to 8 As shown, the present invention provides a technical solution: a lithium battery storage device capable of rapid heat dissipation and cooling, comprising a housing 1, a top cover 2 disposed on the top of the housing 1, a battery pack 3 disposed inside the housing 1, and further comprising:

[0032] Heat dissipation mechanism 4 is fixedly installed on the outer casing 1;

[0033] Reinforcing mechanism 5 is also fixedly mounted on the outer casing 1;

[0034] The upper and lower ends of the battery pack 3 are respectively fixedly connected to the lower surface of the top cover 2 and the bottom upper surface of the outer shell 1. The battery pack 3 is set up inverted, and heat dissipation fins 31 are fixedly connected to the outer surface of the battery pack 3.

[0035] The heat dissipation mechanism 4 includes a heat dissipation plate 41, which is symmetrically and fixedly embedded in the outer surfaces of both sides of the outer shell 1. The heat dissipation plate 41 has a pre-drilled through hole, and air inlet pipes 42 are symmetrically and fixedly connected to the outer surfaces of both sides of the heat dissipation plate 41. A fan 43 is rotatably connected inside the air inlet pipes 42 through a connecting rod.

[0036] A limiting rod 44 is fixedly connected to the surface of the end of the air inlet pipe 42 away from the outer casing 1. Three limiting rods 44 are set at fixed intervals around the central axis of the air inlet pipe 42. A connecting frame 45 is fixedly connected to the end of the limiting rod 44 away from the air inlet pipe 42. A connecting shaft 46 is rotatably connected through the central axis of the connecting frame 45. The connecting shaft 46 is set as a threaded shaft. The end of the connecting shaft 46 away from the connecting frame 45 is rotatably connected to the rotating shaft of the fan 43. The end of the connecting shaft 46 near the rotating shaft of the fan 43 is magnetic.

[0037] The outer surface of the connecting shaft 46 is connected to a closed disc 47 by a thread. The edge of the closed disc 47 is slidably sleeved on the outer surface of the limiting rod 44. The diameter of the closed disc 47 is the same as the outer diameter of the air inlet pipe 42.

[0038] Second embodiment: as follows Figures 1 to 8 As shown, the reinforcing mechanism 5 includes a compression bladder 51, which is fixedly connected to the outer surface of the closed disc 47. The side of the compression bladder 51 away from the closed disc 47 is fixedly connected to the inner surface of the connecting frame 45. An elastic telescopic rod 52 is fixedly connected to the lower edge of the top cover 2. The elastic telescopic rod 52 is fixedly connected to the upper surface of the top edge of the outer shell 1. The internal cavity of the elastic telescopic rod 52 is connected to the internal cavity of the compression bladder 51 through a hose.

[0039] The inner surfaces of the top two sides of the outer casing 1 are symmetrically provided with mounting grooves 53. An expansion bladder 54 is fixedly embedded inside the mounting groove 53. The internal cavity of the expansion bladder 54 is connected to the internal cavity of the compression bladder 51 through a hose. An insertion block 55 is fixedly connected to the outer surface of the expansion bladder 54. The insertion block 55 is slidably inserted into the mounting groove 53.

[0040] The outer casing 1 has symmetrically provided grooves 56 on both sides of the outer wall. The grooves 56 are located on the outer side of the heat sink 41. The two ends of the grooves 56 are symmetrically rotatably connected to the mounting rods 57. The mounting rods 57 are threaded rods. The mounting rods 57 are arranged in pairs as a group. The same group of mounting rods 57 is connected to the moving strip 58 by thread. The upper surface of the moving strip 58 is fixedly connected to the corrugated plate 59. The corrugated plate 59 is located on the outer side of the heat sink 41.

[0041] A transmission belt 510 is rotatably connected to the top outer surface of the mounting rod 57. A drive rod 511 is rotatably connected to the end of the transmission belt 510 away from the mounting rod 57. The drive rod 511 is rotatably connected to the top outer surface of the outer shell 1. The drive rod 511 is a threaded rod, and the top of the drive rod 511 is threadedly connected to the upper edge of the top cover 2.

[0042] An elastic telescopic plate 512 is fixedly embedded at the bottom of the slide groove 56. The elastic telescopic plate 512 is located directly below the moving strip 58. Auxiliary grooves 513 are symmetrically opened on both sides of the slide groove 56. The auxiliary grooves 513 are located in the wall of the outer shell 1. An auxiliary bladder 514 is fixedly connected inside the auxiliary groove 513. The internal cavity of the auxiliary bladder 514 is connected to the internal cavity of the elastic telescopic plate 512. A sealing strip 515 is fixedly connected to the outer surface of the auxiliary bladder 514. The sealing strip 515 is slidably connected in the auxiliary groove 513. The end of the sealing strip 515 away from the auxiliary bladder 514 is directly opposite to the outer surfaces of both sides of the corrugated plate 59.

[0043] During operation, the battery pack 3 is placed inside the outer casing 1. The heat generated by the battery pack 3 during operation is dissipated through the heat sink 41 on the outer casing 1. Furthermore, the heat dissipation fins 31 on the battery pack 3 allow for rapid heat dissipation, thus improving the operational stability of the battery pack 3. Simultaneously, the fan 43 is activated by electricity and begins to rotate. The rotation of the fan 43 draws in cool air from the outside and injects it into the outer casing 1, while expelling hot air from the outer casing 1 through the heat sink 41. This significantly improves the airflow within the outer casing 1, thereby greatly enhancing the heat dissipation effect of the battery pack 3 during operation. A closed disc 47 is provided on the outer side of the air inlet pipe 42, and the middle of the closed disc 47 is connected to the connecting shaft 46 by a screw... The magnetic connection allows the fan 43 to rotate first, causing the connecting shaft 46 to rotate via magnetism. This causes the closing disc 47 to move along the limiting rod 44 towards the connecting frame 45, opening the air inlet pipe 42. When the closing disc 47 can no longer move along the limiting rod 44, the connecting shaft 46 stops rotating, while the fan 43 continues to rotate. This achieves initial closure of the air inlet pipe 42 via the closing disc 47, preventing the interior of the outer casing 1 from being constantly open when the battery is not working, thus avoiding the problem of insects and dust entering the interior of the outer casing 1. When the closing disc 47 moves towards the connecting frame 45, it compresses the compression bladder 51 on its outer surface. The connecting shaft 46 and the fan 43's shaft are connected by a strong magnet, meaning that initially, the connecting shaft 46 will continue to rotate. The compression bladder 51 is compressed by the closed disc 47, causing it to transfer its internal air pressure to the elastic telescopic rod 52. This causes the elastic telescopic rod 52 to expand upwards, ultimately lifting the top cover 2 upwards. At this time, the air inlet pipe 42 is also opened, thus simultaneously opening the top cover 2 while the fan 43 opens the air inlet pipe 42 to draw air into the outer casing 1. This significantly improves the heat dissipation effect on the battery pack 3 and maintains the working stability of the battery pack 3. When the top cover 2 moves upwards, it simultaneously drives the drive rod 511 to rotate via the thread. The rotation of the drive rod 511 drives the transmission belt 510 at its bottom to rotate, which in turn drives the mounting rod 57 connected to the transmission belt 510 to rotate. In other words, the thread on the mounting rod 57 drives the moving bar 58 to move upwards within the slide groove 56. The process involves compressing the corrugated plate 59 to contract it, simultaneously connecting the heat sink 41 to the outside environment while the air inlet duct 42 is operating. This, in conjunction with the closing disc 47 and the top cover 2, allows the side and top surfaces of the outer casing 1 to be fully opened for auxiliary heat dissipation when the fan 43 is operating, significantly improving the heat dissipation effect on the battery pack 3. After the battery pack 3 has finished operating, the fan 43 reverses, causing the closing disc 47 to close the air inlet duct 42. At the same time, the top cover 2 re-closes the top of the outer casing 1, and further causes the corrugated plate 59 to expand and seal the heat sink 41. This ensures that the internal cavity of the outer casing 1 is completely sealed after the battery pack 3 has finished operating, preventing the internal cavity of the outer casing 1 from being connected to the outside environment for a long time, which could lead to safety hazards for the battery pack 3.When the compression bladder 51 is compressed, its internal air pressure is transferred to the expansion bladder 54, causing the expansion bladder 54 to expand. This pushes the insertion block 55 outward along the mounting groove 53, eventually inserting it between the heat dissipation fins 31 on the battery pack 3. This allows the insertion block 55 to automatically engage with the heat dissipation fins 31 when the top cover 2 is opened, thus securing the top of the battery pack 3. This prevents the battery pack 3 from shaking inside the outer casing 1 due to vibration after the top is opened, ensuring its safety. Simultaneously, when the moving bar 58 moves downward, it eventually compresses the elastic telescopic plate 512, causing the elastic... The compression plate begins to contract, transferring its internal air pressure to the auxiliary bladder 514 within the auxiliary groove 513. This causes the auxiliary bladder 514 to expand outwards, pushing the sealing strip 515 outwards from the auxiliary groove 513. Ultimately, the sealing strip 515 is clamped onto both ends of the flattened corrugated plate 59. This achieves simultaneous compression and sealing of both sides of the corrugated plate 59 while sealing the heat dissipation plate 41. This prevents moisture from entering the interior of the outer casing 1 through the sides of the corrugated plate 59, thus ensuring the safety of the battery pack 3. While ensuring heat dissipation for the battery pack 3, it also maximizes its safety when the battery pack 3 is not in operation.
