[0002] Lithium iron phosphate (LIFP) batteries are a variant of lithium-ion batteries that offer high safety, long cycle life, and high energy density. Using LFP as the cathode material, they offer high thermal stability and safety, making them widely used in electric vehicles, energy storage systems, and other fields.

[0003] Lithium iron phosphate batteries are prone to thermal runaway at high temperatures, which affects battery performance and even creates safety hazards. Existing lithium iron phosphate battery energy storage devices generally set heat sinks or heat sinks on the surface or inside of the lithium iron phosphate battery to absorb heat and dissipate the heat through heat transfer to ensure the temperature of the lithium iron phosphate battery. However, the heat dissipation effect of this method is poor, and as external accessories, the heat sinks and heat sinks are easily damaged by mechanical damage and external environmental influences, which again leads to a decrease in heat dissipation performance or damage.

[0004] Therefore, we need to design a lithium iron phosphate battery energy storage device with heat dissipation function. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0023] Example: A lithium iron phosphate battery energy storage device with heat dissipation function, such as Figure 1-Figure 5 As shown, it includes a support leg 1, a cooling shell 2, a support frame 3, an isolation plate 4, a breathable plate 5, a cover plate 6, a storage frame 7, a limit plate 9, a fixed plate 10, a water pump 11, a water pumping pipe 12, a water delivery pipe 13 and a cooling pipe 14. The cooling shell 2 is welded to the rear side of the top of the support leg 1, the isolation plate 4 is welded to the front side of the top of the support leg 1, the breathable plate 5 is fixedly connected to the top of the isolation plate 4, the support frame 3 is welded to the top of the breathable plate 5, the cover plate 6 is fixedly connected to the front side of the support frame 3, the storage frame 7 is fixedly connected to the top of the breathable plate 5, the storage frame 7 is located in the support frame 3, and a fixed plate is welded in the middle of the storage frame 7 10. A group of limit plates 9 are fixedly connected to the fixed plate 10, and another group of limit plates 9 are fixedly connected to the bottom of the storage frame 7. A battery can be placed between every two limit plates 9 in the front and rear. A water pump 11 is fixedly installed on the upper inner side of the cooling shell 2, and a water suction pipe 12 is fixedly connected to the pump head of the water pump 11. A water pipe 13 is fixedly connected to the top of the water pump 11. A cooling pipe 14 is provided on the upper part of the support frame 3 and the inside of the breathable plate 5. The cooling pipe 14 surrounds the storage frame 7. The water pipe 13 is inserted into the support frame 3 and the cooling shell 2, and the water pipe 13 is connected to the cooling pipe 14.

[0024] like Figure 4-Figure 6 As shown, it also includes a fixed frame 16, a fan 17, a support plate 18 and a refrigerator 19. A fixed frame 16 is welded between the front parts of the two legs 1 that are close to each other. A fan 17 is installed in the bottom center of the fixed frame 16. The top of the fixed frame 16 is fixedly connected to the support plate 18. The refrigerator 19 is fixedly installed symmetrically on the top of the support plate 18. The refrigerator 19 is located inside the isolation plate 4.

[0025] like Figure 1 As shown, a heat conducting plate 20 is also included. The support frame 3 and the top of the cooling shell 2 are fixedly connected with the heat conducting plate 20. The inner side of the heat conducting plate 20 has a heat dissipation groove for dissipating heat.

[0026] like Figure 1-Figure 3 As shown, a faucet 15 is also included, and the end of the cooling pipe 14 is connected to the faucet 15.

[0027] like Figure 3 As shown, an insulating plate 8 is also included, and the insulating plate 8 is fixedly installed on the right side of the storage frame 7.

[0028] When the device needs to be used, it is first placed horizontally on a horizontal surface, and then a certain amount of coolant is poured into the upper cooling shell 2, and then a bucket for collecting the coolant is placed at the bottom of the faucet 15. When the batteries in the storage frame 7 are used for too long, which will cause the device to dissipate too much heat, the water pump 11 and the fan 17 can be started by the controller, and then the faucet 15 is opened. Under the action of the water pump 11, the coolant passes through the water pipe 12 from the inside of the cooling shell 2 to the water tank of the water pump 11, and then under the action of the water pump 11 again, the coolant passes through the water supply pipe 13 from the water tank of the water pump 11 to the cooling pipe 14. Under the influence of the thrust of the water pump 11 and the gravity of the coolant itself, the coolant slowly flows to the entire cooling pipe 14. Under the effect of heat conduction, the heat dissipated by the battery is absorbed by the coolant, and then the coolant that absorbs part of the heat flows out of the faucet 15 to the bucket at the bottom. When it is full, the bucket at the bottom of the faucet 15 can be removed, and then the coolant is cooled again for secondary use.

[0029] While the coolant absorbs the heat dissipated by the battery, the fan 17 at the bottom of the fixed frame 16 starts to rotate, transferring the wind used to dissipate the heat upward. When the wind passes through the refrigerator 19, the air pushed by the wind is cooled under the action of the refrigerator 19, and then the storage frame 7 is cooled through the air permeable plate 5. When the temperature of the battery in the storage frame 7 drops, the fan and water pump 11 are turned off, and the faucet 15 is turned on.

[0030] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
