[0022] Embodiment:

[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution: an immersion liquid-cooled energy storage battery box, including a mounting seat 1; a battery module 5; a soaking component 2, the bottom of the soaking component 2 is fixedly connected to the top of the mounting seat 1, and the soaking component 2 is used to cool the battery module 5; a fixing component 3, the outside of the fixing component 3 is fixedly connected to the inside of the soaking component 2, and the inside of the fixing component 3 is slidably connected to the outside of the battery module 5, and the fixing component 3 is used to fix the battery module 5; a sealing component 4, the bottom of the sealing component 4 is slidably connected to the top of the fixing component 3. When in use, the battery module 5 is placed into the fixing component 3, and then the sealing component 4 is fixed to the top of the fixing component 3 by bolts. When in use, the battery module 5 emits a large amount of heat, and the soaking component 2 cools the battery box through the coolant. By setting the soaking component 2, the battery box is cooled, the coolant wraps the battery module 5, and the battery module 5 is comprehensively dissipated of heat, accelerating the cooling speed of the battery box and enhancing the heat dissipation effect. By setting the fixing component 3, the coolant and the battery are isolated, avoiding the direct contact between the battery and the liquid, preventing the problem that the liquid is easy to corrode the battery after long-term use, and ensuring the normal use of the battery.

[0024] The soaking component 2 includes a soaking chamber 21. The inner side of the soaking chamber 21 is fixedly connected to the outer side of the fixing component 3. A water inlet pipe 22 is fixedly connected to the outer side of the soaking chamber 21. During use, the coolant from the outside is sent into the soaking chamber 21 through the water inlet pipe 22. The coolant exchanges heat with the battery module 5 through the fixing component 3, reducing the temperature of the battery module 5. By setting the soaking component 2, heat dissipation of the battery module 5 is carried out, accelerating the cooling speed of the battery box and enhancing the heat dissipation effect.

[0025] A water guide groove 23 is formed in the wall of the soaking chamber 21. A water receiving chamber 24 is fixedly connected to the bottom of the soaking chamber 21. The bottom of the water receiving chamber 24 is fixedly connected to the top of the mounting base 1. A water outlet pipe 25 is fixedly connected to the bottom of the water receiving chamber 24. During use, when the coolant needs to be replaced, the valve at the water outlet pipe 25 is opened. The coolant flows downward along the water guide groove 23 into the water receiving chamber 24, then flows to the water outlet pipe 25 along the water receiving chamber 24 and then flows out to the outside. After the outflowing coolant is cooled, it is sent back to the water inlet pipe 22 for recycling. By setting the water guide groove 23, the outflow of the coolant is guided, and when the coolant needs to be pumped out, it can also prevent more coolant from remaining inside the device.

[0026] The fixing component 3 includes a housing 31. The outer side of the housing 31 is fixedly connected to the inner side of the soaking chamber 21. The inner side of the housing 31 is slidably connected to the outer side of the battery module 5. A soaking groove 32 is formed in the wall of the housing 31. Heat dissipation fins 33 are fixedly connected to the outer side of the housing 31. During use, the battery module 5 is placed inside the housing 31. The water inlet pipe 22 sends the coolant from the outside into the soaking chamber 21. The coolant flows to the soaking groove 32. Since the soaking groove 32 is formed between the batteries, the coolant can wrap the batteries from all around. The heat dissipation fins 33 increase the contact area between the battery and the coolant. During use, the battery module 5 releases a large amount of heat. The coolant exchanges heat with the battery module 5 through the fixing component 3, reducing the temperature of the battery module 5. By setting the fixing component 3, the coolant and the battery are isolated, avoiding direct contact between the battery and the liquid, preventing battery corrosion, and allowing the coolant to fully exchange heat with the battery, with uniform cooling and accelerating the heat dissipation speed of the battery.

[0027] The sealing component 4 includes a top plate 41. The bottom of the top plate 41 is slidably connected to the top of the outer shell 31. A fixing plate 42 is fixedly connected to the outside of the top plate 41. A positioning hole 43 is formed in the wall of the fixing plate 42. When in use, align the top plate 41 in the sealing component 4 with the outer shell 31, move the top plate 41 and the fixing plate 42 downward. The top plate 41 and the fixing plate 42 are attached to the outside of the outer shell 31, and the fixing plate 42 is fixed through bolts and the positioning hole 43. By providing the sealing component 4, the sealing performance of the battery module 5 is enhanced, preventing the coolant or other impurities from contacting the battery, avoiding corrosion of the battery, and ensuring the normal operation of the battery module 5.

[0028] A return spring 44 is fixedly connected to the top of the inner cavity of the top plate 41. The bottom end of the return spring 44 is fixedly connected to a sealing ring 45. The outside of the sealing ring 45 is slidably connected to the inside of the top plate 41. When in use, the top plate 41 drives the return spring 44 and the sealing ring 45 to move downward. The sealing ring 45 contacts the top of the outer shell 31. The sealing ring 45 receives a reaction force and drives the return spring 44 to compress upward. Under the action of its own elastic force, the return spring 44 drives the sealing ring 45 to closely adhere to the top of the outer shell 31. By providing the return spring 44 and the sealing ring 45, the sealing performance at the battery is enhanced to protect the battery.

[0029] Working principle:

[0030] When in use, first place the battery module 5 inside the outer shell 31, then align the top plate 41 in the sealing component 4 with the outer shell 31, move the top plate 41 and the fixing plate 42 downward. The top plate 41 and the fixing plate 42 are attached to the outside of the outer shell 31, and the fixing plate 42 is fixed through bolts and the positioning hole 43. At the same time, the top plate 41 drives the return spring 44 and the sealing ring 45 to move downward. The sealing ring 45 contacts the top of the outer shell 31. The sealing ring 45 receives a reaction force and drives the return spring 44 to compress upward. Under the action of its own elastic force, the return spring 44 drives the sealing ring 45 to closely adhere to the top of the outer shell 31. Install the battery box through the mounting seat 1;

[0031] When in use, the battery module 5 releases a large amount of heat. The water inlet pipe 22 sends the external coolant into the soaking chamber 21. The coolant flows to the soaking tank 32. Since the soaking tank 32 is opened between the batteries, the coolant can wrap the batteries from all around. The heat sink 33 increases the contact area between the battery and the coolant. When in use, the battery module 5 releases a large amount of heat. The coolant exchanges heat with the battery module 5 through the fixing component 3 to reduce the temperature of the battery module 5;

[0032] When the coolant needs to be replaced, open the valve at the water outlet pipe 25. The coolant flows downward along the water guiding groove 23 into the water receiving chamber 24. The coolant flows along the water receiving chamber 24 to the water outlet pipe 25, and then flows along the water outlet pipe 25 to the outside. After the discharged coolant is cooled, it is sent back to the water inlet pipe 22 for recycling.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model shall be implemented by conventional means in the art without special explanation and limitation.
