Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, specifically a modular assembly and heat dissipation frame structure for energy storage equipment clusters. Background Technology

[0002] Energy storage device clusters are the core components of electrochemical energy storage systems. They consist of multiple battery packs connected in series and are used to store and release energy. When assembling energy storage battery packs, if the battery packs are of different sizes, it is difficult to effectively fix them with the battery racks used to fix the battery packs. Furthermore, when dissipating heat from the energy storage batteries on the battery racks, the heat dissipation efficiency of the battery packs located at the top and bottom will vary significantly, affecting the normal use of the device.

[0003] For example, a modular battery cluster described in patent CN216720061U includes a battery rack and ventilation ducts. The battery rack contains multiple battery clusters, and the ventilation ducts include a primary duct and a secondary duct. The primary duct is connected to the secondary duct, and the secondary duct is connected to the battery rack. The primary duct is equipped with an airflow regulating device, which ensures uniform airflow into each battery cluster through the ventilation ducts, resulting in a small system temperature difference. It is also widely applicable and easy to install and disassemble. However, when storing battery packs, the support frame on the battery rack cannot be adjusted according to the size of the battery packs. Furthermore, when cooling the battery packs, the cold air flows from top to bottom, causing a difference in heat dissipation efficiency between the battery packs at the top and bottom, which affects the service life of the device.

[0004] Based on this, a modular assembly and heat dissipation rack structure for energy storage device clusters is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-5 As shown, a modular assembly and heat dissipation rack structure for an energy storage device cluster includes a battery rack 1. A protective door 11 is rotatably connected to the front end of the battery rack 1. A first filter 12 is symmetrically and detachably connected to the top of the battery rack 1. A second filter 13 is symmetrically and detachably connected to the bottom end of the battery rack 1. Rectangular slots are uniformly opened inside the battery rack 1, and heat dissipation fins 14 are arranged in each of the rectangular slots. A temperature sensor is arranged inside the battery rack 1. Support components 2 are uniformly arranged inside the battery rack 1. Filter components 3 are arranged on the side wall of the battery rack 1. Positioning components 4 for fixing the filter components 3 are arranged on the side wall of the battery rack 1. The support assembly 2 includes a support frame 21, and a slider 22 is fixedly connected to the side wall of the support frame 21. The slider 22 is slidably connected to a groove opened inside the battery holder 1. The slider 22 is T-shaped. The filter assembly 3 includes a third filter 31, which is inserted into a slot on the battery holder 1. A locking block 32 is symmetrically fixedly connected to the side wall of the third filter 31, and the locking block 32 is slidably connected to a sliding groove on the battery holder 1.

[0023] In this embodiment, battery modules of different heights can be assembled and placed using the support component 2. When the battery module is working, the heat sink 14 and the cooling fan 16 work together to dissipate heat from the battery module. Furthermore, by removing the restriction of the positioning component 4 on the filter component 3, the filter component 3 can be removed and the cooling fan 16 can be inspected.

[0024] In an optional embodiment, such as Figure 2 As shown, mounting brackets 15 are uniformly fixedly connected inside the battery rack 1. A cooling fan 16 is fixedly connected to the end of the mounting bracket 15. The cooling fan 16 is positioned corresponding to the third filter 31. It absorbs the heat emitted by the battery module during operation through the heat sink 14. At the same time, it works with the cooling fan 16 to remove the heat from the heat sink 14. During the operation of the cooling fan 16, outside air enters through the first filter 12 and the second filter 13 and is discharged through the third filter 31, which accelerates the airflow inside the battery rack 1. This provides a good heat dissipation effect for the battery modules distributed in the upper and lower positions inside the battery rack 1.

[0025] In an optional embodiment, such as Figure 4 As shown, the support frame 21 is L-shaped. One end of the slider 22 is fixedly connected to the insertion block 23. The insertion block 23 is inserted into the slot on the battery rack 1. The insertion block 23 is symmetrically provided with fixing bolts 24 inside. The fixing bolts 24 are threadedly connected to the internal threaded holes on the battery rack 1. The position of the support frame 21 is adjusted according to the batteries to be placed. By unscrewing the fixing bolts 24, the restriction between the fixing bolts 24 and the insertion block 23 and the battery rack 1 is released. Then the support frame 21 can be pulled, which drives the slider 22 to move synchronously, so that the slider 22 is disengaged from the slide groove on the battery rack 1. Then the slider 22 is reconnected to the slide groove at a suitable height. The insertion block 23 and the battery rack 1 are restricted by the fixing bolts 24 to keep the support frame 21 stable, which facilitates the subsequent support and storage of the battery module.

[0026] In an optional embodiment, such as Figure 3As shown, the battery holder 1 has an L-shaped sliding groove for the sliding block 32. By releasing the restriction of the positioning component 4 on the block 32, the third filter 31 is rotated, which drives the block 32 to rotate synchronously. When it can no longer rotate, the third filter 31 can be pulled to remove it, and then the cooling fan 16 can be inspected.

[0027] In an optional embodiment, such as Figure 5 As shown, the positioning component 4 includes a first docking block 41. The side wall of the first docking block 41 is fixedly connected to the side wall of the battery holder 1. A sliding groove is opened on the first docking block 41 to slidably connect a rod 42. The rod 42 passes through the outer wall of the battery holder 1 and is inserted into a positioning hole opened on the locking block 32. A rotating plate 43 is fixedly connected to the end of the rod 42. A spring 44 is sleeved on the outer wall of the rod 42. One end of the spring 44 is fixedly connected to the side wall of the first docking block 41, and the other end is fixedly connected to the end of the rotating plate 43. By pulling the second docking block 45, the rotating plate 43 and the rod 42 move synchronously, causing the spring 44 to stretch and releasing the rod 42 from the restriction of the locking block 32.

[0028] In an optional embodiment, such as Figure 5 As shown, a second mating block 45 is rotatably connected to the end of the rotating plate 43. The second mating block 45 and the first mating block 41 are interlocked, so that the first mating block 41 and the second mating block 45 can achieve a self-locking effect when they are mated at the protrusion and at the groove, thus facilitating subsequent operations.

[0029] The above embodiments disclose a modular assembly and heat dissipation rack structure for energy storage device clusters. When placing battery modules, the position of the support frame 21 can be adjusted according to the number of batteries to be placed. By unscrewing the fixing bolts 24, the constraint between the insert block 23 and the battery rack 1 is released. Then, the support frame 21 can be pulled, causing the slider 22 to move synchronously, disengaging the slider 22 from the groove on the battery rack 1. The slider 22 is then reconnected to the groove at a suitable height, and the insert block 23 is connected to the battery rack 1 using the fixing bolts 24. Battery rack 1 is used to restrict the support frame 21, ensuring its stability and facilitating subsequent support and storage of the battery modules. After all battery modules are assembled and secured, they can be put into use. During use, the heat sink 14 absorbs the heat generated by the battery modules during operation. When the temperature sensor detects that the temperature inside battery rack 1 has reached a preset threshold, the cooling fan 16 starts, removing the heat from the heat sink 14. During the operation of the cooling fan 16, outside air enters through the first filter 12 and the second filter 13, and exits through the third filter 31, accelerating the cooling of the battery rack. The internal airflow velocity effectively dissipates heat from the battery modules located both above and below the battery rack 1. Simultaneously, the first filter 12 and the second filter 13 filter the air, preventing dust from entering the battery rack 1 and falling onto the battery modules. When the first filter 12 and the second filter 13 need to be replaced, they can be removed and replaced. When the cooling fan 16 needs maintenance, the third filter 31 is removed. By pulling the second connecting block 45, the rotating plate 43 and the insertion rod 42 move synchronously, stretching the spring 44 and releasing the insertion rod 42. By restricting the locking block 32, the third filter 31 can be rotated, causing the locking block 32 to rotate synchronously. When it can no longer rotate, the third filter 31 can be pulled and removed. Then, the cooling fan 16 can be inspected. In summary, battery modules of different heights can be assembled and placed using the support component 2. When the battery module is working, the heat sink 14 and the cooling fan 16 work together to dissipate heat from the battery module. Furthermore, by removing the restriction of the filter component 3 by the positioning component 4, the filter component 3 can be removed, and the cooling fan 16 can be inspected.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
