Description

Technical Field

[0001] The utility model application relates to the technical field of lithium batteries, and specifically to a lithium battery energy storage device with stable heat dissipation. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the highly active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] In the prior art, a heat dissipation fan is used to dissipate heat from lithium batteries. However, the heat dissipation fan occupies a large space when installed. When the heat dissipation fan is used for a long time, the friction between the fan blades and the air causes the electrons to transfer, thereby becoming charged. After being charged, the fan blades attract light and small objects and are easily contaminated with dust. The dust in the air causes the fan blades with dust to vibrate easily, resulting in a decrease in the number of revolutions and wind force, thereby reducing the heat dissipation effect. The heat dissipation fan needs to be disassembled and cleaned regularly, and the overall operation is relatively troublesome. Summary of the invention

[0004] In order to solve the problem that when the cooling fan is used for a long time, the friction between the fan blades and the air causes the electrons to transfer, thereby becoming charged, attracting light and small objects after being charged, and easily getting dust on the dust in the air. The fan blades with dust are prone to vibration, which reduces the number of revolutions and wind force, thereby reducing the cooling effect and requiring the cooling fan to be disassembled and cleaned regularly, the utility model provides a lithium battery energy storage device with stable heat dissipation to solve the above problem.

One end of the spring 18 is fixedly connected to the built-in plate 8, and a heat dissipation port 10 is provided on one side of one of the built-in plates 8.

[0026] Specifically, the heat dissipation fins 23 are installed on both sides of the heat dissipation plate 20, which can increase the heat dissipation area of ​​the heat dissipation plate 20. The cooling tube 22 is arranged horizontally, and its top is overlapped with the heat dissipation fins 23, which can increase the heat volatilization of the surface of the heat dissipation fins 23, thereby accelerating the heat dissipation of the heat dissipation plate 20. Since the heat dissipation plate 20 and the cooling tube 1 21 are overlapped with the outer annular surface of the battery body 13, the heat volatilization of the surface of the battery body 13 can be accelerated, and the accumulation of heat inside the protective shell 2 can be reduced to avoid the high temperature inside the protective shell 2. A liquid filling port is provided on the top of one of the cooling tubes 22 to facilitate the injection of coolant, and the cooling box 11 is convenient for The coolant is recovered and discharged, and the top of the cooling box 11 is overlapped with the limit plate 17. The cooling box 11 and the limit plate 17 are both made of heat-conducting materials. The cooling box 11 can be used to assist the limit plate 17 in cooling, thereby achieving stable heat dissipation of the battery body 13 on the limit plate 12 and the limit plate 17. The spring 18 can be used to drive the positioning plate 19 to move along the limit plate 12, so that the side of the positioning plate 19 away from the spring 18 is overlapped with the battery body 13, thereby limiting the battery body 13 and reducing the movement of the battery body 13 on the limit plate 12, thereby improving the stability of the battery body 13 during installation and use.

[0027] As an optimization solution, Figure 3-Figure 5As shown, a reinforcement frame 15 is overlapped on the top of the positioning plate 19, one side of the reinforcement frame 15 is fixedly connected to the inner wall of the protective shell 2, a support member 14 is hinged on the top of the reinforcement frame 15, one side of the support member 14 is engaged with a limit strip 16, one side of the limit strip 16 is fixedly connected to the inner wall of the protective shell 2, an elastic telescopic rod 9 is fixedly connected to the top of the reinforcement frame 15, the top of the elastic telescopic rod 9 is overlapped with the top cover 1, a reinforcement rod 5 is inserted at the bottom of the top cover 1, the bottom of the reinforcement rod 5 is fixedly connected to the base 4, the top of the base 4 is slidably connected to an anti-collision plate 3, one side of the anti-collision plate 3 is rotatably connected to an anti-collision roller 6, and one side of the anti-collision plate 3 is overlapped with a buffer spring 7, one side of the buffer spring 7 is fixedly connected to the protective shell 2.

[0028] Specifically, the protective shell 2 can be used to support the installation of the reinforcement frame 15, the elastic telescopic rod 9 can connect the top cover 1 and the reinforcement frame 15, and provide buffering protection for the top of the reinforcement frame 15. The support member 14 is hinged to the reinforcement frame 15, so that the support member 14 can rotate at the top of the reinforcement frame 15, thereby controlling the engagement and separation of the support member 14 and the limit bar 16. When the support member 14 is engaged, support and reinforcement of the interior of the protective shell 2 can be achieved. The anti-collision plate 3 and the anti-collision roller 6 are used in combination to improve the buffering effect on one side of the protective shell 2, thereby reducing the collision damage to the protective shell 2 caused by external force, reducing the damage to the protective shell 2, thereby ensuring the normal energy storage of the internal battery body 13, reducing the damage to the battery body 13, and ensuring the safe use of the entire device.

[0029] Working principle: First, the whole device can be installed and fixed using the base 4. When it is hit by external force, the reinforcement rod 5 can support and reinforce the two sides of the protective shell 2. When the other two sides of the protective shell 2 are hit by external force, the anti-collision plate 3 is forced to move toward the side close to the protective shell 2, and the buffer spring sheet 7 is compressed to achieve buffer protection for one side of the protective shell 2. When the external force hits the position between the two anti-collision plates 3, the anti-collision roller 6 rotates to change the direction of the external force, thereby reducing the impact and damage to the protective shell 2. The battery body 13 is respectively connected to the circuits on the limit plate 1 12 and the limit plate 2 17. When the multiple battery bodies 13 inside the protective shell 2 are working, the cooling pipe 1 21 is located between the battery bodies 13 and can contact the outer ring surface of the battery body 13. The bottom of the heat sink 20 contacts the outer annular surface of the battery body 13, and the heat sink fins 23 can increase the heat dissipation area of ​​the heat sink 20. At the same time, the top of the cooling tube 22 contacts the heat sink fins 23, which can accelerate the heat dissipation on the surface of the heat sink fins 23, thereby improving the heat dissipation effect on the battery body 13 and reducing the heat accumulation on the surface of the battery body 13. The external air can enter the protective shell 2 through the filter on the top cover 1 and then be discharged through the heat dissipation port 10, thereby achieving stable heat dissipation inside the protective shell 2. By engaging the support member 14 with the limit bar 16, a triangular structure can be formed on the top of the reinforcement frame 15 to support the inside of the protective shell 2, thereby improving the strength of the inside of the protective shell 2, reducing the stress deformation at the top of the reinforcement frame 15, and extending the service life of the protective shell 2.
