Description

Technical Field

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

[0002] A lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Through energy storage lithium battery control devices, it stores electrical energy during off-peak hours and releases electrical energy during peak hours, balancing the differences in grid load and improving grid operating efficiency. At the same time, it can also ensure the continuous power supply to critical facilities during power outages, thereby enhancing power supply reliability.

[0003] For example, Chinese patent CN117594911B discloses a photovoltaic energy storage lithium battery pack. This device sets a heat dissipation mechanism inside the housing to cool the lithium battery; an airflow distribution mechanism is set inside the housing and can move multiple C-shaped placement frames up and down sequentially at any time; through the cooperation of the heat dissipation mechanism and the airflow distribution mechanism, the multiple C-shaped placement frames can form a "serpentine flow channel" whose direction can be changed intermittently, and the cooling fan delivers airflow into the "serpentine flow channel" to cool the lithium battery comprehensively.

[0004] When current flows through the internal conductors (electrodes / electrolyte) of a battery, heat is generated due to internal resistance. Especially in high-current charging and discharging scenarios (such as the instantaneous response of peak-shaving power plants), the local temperature rise can reach tens of degrees Celsius. Therefore, it is necessary to dissipate heat and cool down the lithium battery. Existing lithium batteries often use cooling fans for air cooling. However, in coastal areas with high salinity and humidity, the moisture in the air will come into contact with the surface of the lithium battery under the action of the fan. When the temperature difference is large, the moisture will condense on the surface of the lithium battery. The formation of condensation not only increases the risk of short circuit in the lithium battery, but also corrodes the terminals of the lithium battery, affecting the working life of the lithium battery. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This solution incorporates a moisture-absorbing component. When air passes through the mesh on the surface of the moisture-absorbing plate, it comes into full contact with the plate. The plate absorbs moisture from the air, effectively reducing the amount of moisture entering the machine. This not only reduces the likelihood of condensation inside the machine, thus lowering the risk of short circuits in the lithium battery, but also reduces the chance of corrosion on metal connectors, thereby extending their service life.

[0019] 2. This solution uses components such as sleeves and piston rods to push the moisture-absorbing plate, causing it to move up and down inside the through hole. During this movement, the moisture-absorbing plate drives the vibrating block to slide in and out of the vibration groove. This causes the moisture-absorbing plate to vibrate to a certain extent, which accelerates the shedding of dust from the surface of the moisture-absorbing plate. This effectively reduces the adhesion of foreign matter to the surface of the moisture-absorbing plate, thereby ensuring the airflow speed inside the moisture-absorbing plate and extending the working time of the moisture-absorbing plate to a certain extent.

[0020] 3. This solution incorporates an emergency component. When the internal temperature of the device becomes too high, the sealing plate will pop out of the slot under the elastic force of spring one. After the sealing plate disengages from the slot, air can flow through the slot to the inside and outside of the device. By accelerating the airflow, the internal lithium battery can be quickly cooled down, thereby effectively reducing the risk of spontaneous combustion and fire caused by overheating of the lithium battery. This effectively improves the safety of the lithium battery during energy storage and dissipation. Attached Figure Description

[0032] 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.

[0033] Please see Figures 1 to 8 This invention provides a technical solution:

[0034] A lithium battery energy storage device based on rapid heat dissipation and cooling includes a body 12 and a lithium battery 19. A bracket 18 for placing the lithium battery 19 is fixedly connected to the inner surface of the body 12. A fixing sleeve 32 is fixedly connected to the lower outer surface of the body 12. A through hole 55 is opened through the lower outer surface of the body 12. A moisture-absorbing component is provided inside the fixing sleeve 32.

[0035] The moisture-absorbing assembly includes a moisture-absorbing plate 43 slidably connected to the inner surface of the through hole 55, a vibrating block 44 fixedly connected to the outer surface of the moisture-absorbing plate 43, a vibration groove 42 penetrating through the outer surface of the through hole 55, a sleeve 45 fixedly connected to the upper side of the inner surface of the fixing sleeve 32, a piston plate 46 slidably connected to the inner side of the sleeve 45, a piston rod 47 fixedly connected to the upper outer surface of the piston plate 46, the upper end of the piston rod 47 fixedly connected to the lower outer surface of the moisture-absorbing plate 43, and an overflow groove 48 embedded in the inner side of the fixing sleeve 32, which communicates with the inside of the piston cylinder.

[0036] The vibration grooves 42 are in several groups and are arranged in a linear array. The outer surfaces of the vibration grooves 42 and the vibration blocks 44 are both arc-shaped. The piston cylinders and piston rods 47 are in two groups and are symmetrically distributed. The moisture-absorbing plate 43 is made of elastic material.

[0037] A cover plate 14 is fixedly connected to the upper outer surface of the body 12. The upper outer surface of the cover plate 14 is inclined. Rain shields 15 are fixedly connected to the left and right ends of the outer surface of the body 12. Support legs 11 are fixedly connected to the lower outer surface of the body 12. A wire 16 is electrically connected between the two sets of lithium batteries 19. A panel 17 is snapped onto the front outer surface of the body 12.

[0038] By adopting the above technical solution, the bracket 18 inside the body 12 is used to fix and support the lithium battery 19, thereby installing the lithium battery 19 inside the body 12. The panel 17 can provide a sealing and protective function for the front side of the body 12. Adjacent sets of lithium batteries 19 are connected in series by wires 16. When the lithium battery 19 inside the body 12 is cooled down, the air in the surrounding environment is cooled by external force through the surface of the fixing sleeve 32 on the lower side of the body 12. Then, the gas inside the fixing sleeve 32 passes through the moisture-absorbing plate 43 and is guided by a guide. The tube enters the interior of the body 12. The surface of the moisture-absorbing plate 43 is perforated with fine mesh holes. When air passes through the mesh holes on the surface of the moisture-absorbing plate 43, it will come into full contact with the surface of the moisture-absorbing plate 43. The moisture-absorbing plate 43 can absorb the moisture in the air, thereby effectively reducing the amount of moisture entering the interior of the body 12. This not only reduces the probability of condensation forming inside the body 12, which helps to reduce the risk of short circuit in the lithium battery 19, but also reduces the probability of corrosion of metal connectors to a certain extent, thereby effectively extending the working life of the metal connectors.

[0039] During prolonged operation, the fine mesh on the surface of the moisture-absorbing plate 43 can become clogged with dust, affecting the airflow speed inside the plate. At this time, the operator adjusts the air intake pressure inside the fixed sleeve 32. The gas inside the fixed sleeve 32 enters the sleeve 45 through the overflow groove 48. When the gas pressure inside the fixed sleeve 32 fluctuates, the gas pressure inside the sleeve 45 also fluctuates. When the gas pressure increases, the piston plate 46 is pushed upwards by the pressure. During this movement, the piston plate 46 pushes the piston rod 47, thereby... The stopper rod 47 pushes the moisture-absorbing plate 43, causing it to move up and down inside the through hole 55. Several sets of vibration grooves 42 are provided on the surface of the through hole 55. During the movement, the moisture-absorbing plate 43 will drive the vibration block 44 to slide in and out of the vibration groove 42. At this time, the moisture-absorbing plate 43 will generate a certain amplitude of vibration. The vibration can accelerate the falling off of dust on the surface of the moisture-absorbing plate 43, thereby effectively reducing the adhesion of foreign objects on the surface of the moisture-absorbing plate 43. This can effectively ensure the airflow speed inside the moisture-absorbing plate 43 and also extend the working time of the moisture-absorbing plate 43 to a certain extent.

[0040] Specifically, such as Figure 3 ,and Figure 4 As shown, a heat dissipation assembly is provided inside the body 12. The heat dissipation assembly includes a support frame 29 fixedly connected to the inner surface of the body 12. The support frame 29 has a U-shaped structure. A motor 30 is fixedly connected to the lower outer surface of the support frame 29. A drive rod 31 is fixedly connected to the lower end of the output shaft of the motor 30. A fan blade 33 is fixedly connected to the outer surface of the drive rod 31. An air inlet 36 is provided through the outer surface of the fixed sleeve 32.

[0041] The number of air inlets 36 is several groups and arranged in a ring array. A slot 24 is provided through the outer surface of the body 12. A sealing plate 13 is engaged and connected to the inner side of the slot 24. An air guide grille 21 is provided through the outer surface of the sealing plate 13. An air supply pipe 20 is fixedly connected to the outer surface of the support frame 29. The air supply pipe 20 has an L-shaped structure. There are two groups of air supply pipes 20 and they are symmetrically distributed. Air nozzles are evenly arranged on the outer surface of the air supply pipe 20.

[0042] By adopting the above technical solution, when the temperature sensor inside the body 12 detects an increase in temperature, the control system controls the motor 30 to operate electrically. The body 12 is fixedly supported by the support frame 29. At this time, the output shaft of the motor 30 will drive the fan blade 33 to rotate synchronously through the drive rod 31. During the rotation of the fan blade 33, the gas inside the fixed sleeve 32 will be blown upward. The gas is transported through the air supply pipe 20 and blown evenly onto the surface of the lithium battery 19 through the jet nozzle on the surface of the air supply pipe 20. At this time, a negative pressure will be formed inside the fixed sleeve 32, thereby drawing the gas outside the fixed sleeve 32 into the fixed sleeve 32 through the air inlet 36, thereby realizing the continuous injection of air. During the upward flow of air inside the body 12, the air will come into contact with the surface of the lithium battery 19. Then, under pressure, the air will be discharged to the outside of the body 12 through the air guide grille 21 on the surface of the sealing plate 13. The circulation of air can remove the heat inside the body 12, thereby achieving a good ventilation and heat dissipation effect for the lithium battery 19.

[0043] Specifically, such as Figure 4 and Figure 6 As shown, a sealing assembly is provided on the outside of the fixed sleeve 32. The sealing assembly includes an ear seat 49 fixedly connected to the outer surface of the lower end of the body 12. A pin 50 is rotatably connected to the outer surface of the ear seat 49. A movable plate 34 is fixedly connected to the outer surface of the pin 50. A contact plate 35 is fixedly connected to the outer surface of the movable plate 34 near the fixed sleeve 32. The number of movable plates 34 and contact plates 35 are several sets and are distributed corresponding to the air inlet 36.

[0044] The outer surface of the fixed sleeve 32 is embedded with a storage groove 51. A heat-conducting plate 53 is fixedly connected to the inner surface of the storage groove 51. A thermal expansion block 52 is fixedly connected to the outer surface of the heat-conducting plate 53. The inner side of the thermal expansion block 52 is hollow. A partition 54 is fixedly connected to the inner surface of the thermal expansion block 52. The overflow groove 48 has a T-shaped structure and is connected to the interior of the thermal expansion block 52. Both the storage groove 51 and the thermal expansion block 52 are annular.

[0045] By adopting the above technical solution, the fixed sleeve 32 is fixedly installed on the thermal expansion block 52 through the storage groove 51, and the body 12 is rotatably supported by the pin shaft 50 through the ear seat 49, so that the movable plate 34 can be flipped with the pin shaft 50 as the fulcrum. When the internal temperature of the body 12 and the fixed sleeve 32 continues to rise, the heat will be transferred to the interior of the thermal expansion block 52 through the heat conduction plate 53. At this time, the thermal expansion block 52 will expand due to heat and its volume will increase. The partition 54 will divide the space inside the thermal expansion block. The gas inside the fixed sleeve 32 will enter the interior of the thermal expansion block 52 through the overflow groove 48, thereby further increasing the expansion range of the thermal expansion block 52 under the action of gas pressure. As the volume increases, the movable plate 34 is pushed, causing the movable plate 34 to disengage the contact plate 35 from the air inlet 36. At this time, external gas can enter the fixed sleeve 32 through the air inlet 36. When the internal temperature of the body 12 and the fixed sleeve 32 is low, the volume of the thermal expansion block 52 will decrease. At this time, the movable plate 34 will flip downward under the action of gravity, thereby causing the movable plate 34 to seal the air inlet 36 with the contact plate 35. This can reduce the air flow speed to a certain extent, which can help maintain the internal temperature of the body 12 within an appropriate range, and further improve the stability of the lithium battery 19 during energy storage.

[0046] Specifically, such as Figure 4 and Figure 7 As shown, a filter assembly is provided inside the air inlet 36. The filter assembly includes a filter screen 37 that is slidably connected to the inner surface of the air inlet 36. A mounting plate 40 is fixedly connected to the inner surface of the air inlet 36. A spring 41 is fixedly connected to the outer surface of the mounting plate 40. The side of the spring 41 away from the mounting plate 40 is fixedly connected to the filter screen 37. A top block 38 is fixedly connected to the outer surface of the filter screen 37. The end of the top block 38 away from the filter screen 37 is in contact with the outer surface of the contact plate 35.

[0047] By adopting the above technical solution, the air inlet 36 is fixedly installed on the spring 41 by the mounting plate 40. The filter screen 37 set inside the air inlet 36 can effectively reduce the entry of impurities and insects into the fixed sleeve 32, thereby providing a good protective effect against foreign objects in the environment. When the movable plate 34 drives the contact plate 35 to disengage from the top block 38, the filter screen 37 slides along the inner wall of the air inlet 36 under the elastic force of the spring 41. When the movable plate 34 drives the contact plate 35 to move downward, the outer surface of the contact plate 35 contacts the top block 38 and pushes the top block 38. The top block 38 can push the filter screen 37 to move in the opposite direction inside the air inlet 36, and the filter screen 37 squeezes the spring 41. The reciprocating motion of the filter screen 37 can reduce the adhesion of impurities on the surface of the filter screen 37, thereby effectively ensuring the filtration effect of the filter screen 37, and also achieving stable air circulation.

[0048] Specifically, such as Figure 4 , Figure 5 and Figure 8 As shown, an emergency assembly is provided on the outer side of the sealing plate 13. The emergency assembly includes a fixing plate 27 that is fixedly connected to the inner surface of the slot 24. An installation groove 25 is embedded in the lower outer surface of the sealing plate 13. The fixing plate 27 is located inside the installation groove 25 and slides in contact with the inner wall of the installation groove 25. A rubber sleeve 28 is fixedly connected to the outer surface of the fixing plate 27. The outer surface of the rubber sleeve 28 away from the fixing plate 27 is fixedly connected to the inner surface of the installation groove 25.

[0049] A spring 26 is fixedly connected to the outer surface of the fixing plate 27. The end of the spring 26 away from the fixing plate 27 is in contact with the inner wall of the mounting groove 25. The spring 26 is located on the upper side of the rubber sleeve 28. The inner side of the rubber sleeve 28 is filled with thermal expansion gas. A limiting block 23 is fixedly connected to the upper outer surface of the sealing plate 13. A limiting groove 22 is embedded on the upper side of the inner surface of the slot 24. The limiting block 23 engages with the limiting groove 22.

[0050] By adopting the above technical solution, the upper end of the sealing plate 13 is engaged with the inside of the limiting groove 22 by the limiting block 23, thereby fixing the sealing plate 13 to the outside of the body 12. Under the pulling force of the rubber sleeve 28, the sealing plate 13 is stably installed inside the slot 24. When the temperature inside the body 12 is too high, the volume of thermal expansion gas inside the rubber sleeve 28 will continue to increase. When the thermal expansion gas bursts the rubber sleeve 28, the sealing plate 13 will be ejected from the slot 24 under the elastic force of the spring 26. After the sealing plate 13 is separated from the slot 24, air can flow through the slot 24 inside and outside the body 12. By accelerating the air flow, the lithium battery 19 inside the body 12 can be quickly cooled down, thereby effectively reducing the risk of spontaneous combustion fire of the lithium battery 19 due to excessive temperature, and thus effectively improving the safety of the lithium battery 19 in the process of energy storage and release.

[0051] Working principle: When the temperature sensor inside the body 12 detects a temperature increase, the thermal expansion block 52 expands due to heat, increasing its volume. During this expansion, the thermal expansion block 52 pushes the movable plate 34, causing the movable plate 34 to disengage the contact plate 35 from the air inlet 36. When the energy storage lithium battery 19 is working, the output shaft of the motor 30 drives the fan blades 33 to rotate synchronously via the drive rod 31. During rotation, the fan blades 33 blow the gas inside the fixed sleeve 32 upwards. Gas outside the fixed sleeve 32 is drawn into the fixed sleeve 32 through the air inlet 36 and evenly blown onto the surface of the lithium battery 19 through the nozzles on the surface of the air supply pipe 20. The gas inside the fixed sleeve 32 passes through the moisture-absorbing plate 43 and enters the body 12 through the duct. The moisture-absorbing plate 43 absorbs moisture from the air, effectively reducing the amount of moisture entering the body. Inside the body 12, the piston rod 47 pushes the moisture-absorbing plate 43, causing it to move downwards inside the through hole 55. During the movement of the moisture-absorbing plate 43, a certain amplitude of vibration is generated. This vibration can accelerate the shedding of dust from the surface of the moisture-absorbing plate 43, thereby effectively reducing the adhesion of foreign objects on the surface of the moisture-absorbing plate 43. The filter screen 37 installed inside the air inlet 36 can effectively reduce the entry of impurities and insects into the fixed sleeve 32, thus providing a good protective effect against foreign objects in the environment. When the temperature inside the body 12 is too high, the sealing plate 13 will be ejected from the slot 24 under the elastic force of the spring 26. Air can flow through the slot 24 inside and outside the body 12. By accelerating the air flow, the lithium battery 19 inside the body 12 can be quickly cooled down, thereby effectively reducing the risk of spontaneous combustion of the lithium battery 19 due to overheating.
