Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, and in particular to a fully immersed liquid-cooled integrated energy storage cabinet. Background Technology

[0002] The energy storage cabinet contains a large number of energy storage batteries with a high installation density, which makes it easy for internal heat to accumulate. When the internal heat is too high, it will affect the operation of internal components and increase energy consumption.

[0003] Chinese utility model patent CN215644795U discloses an outdoor energy storage battery cabinet, including a cabinet body, multiple battery modules, a fire protection system, a cooling system, and a junction box. The fire protection system includes a suppression host, and the cooling system includes a water-cooled unit. The multiple battery modules are connected to both the suppression host and the water-cooled unit. The junction box is electrically connected to the multiple battery modules, the suppression host, and the water-cooled unit, and is used to control these components. The cabinet body includes a first section and a second section. The multiple battery modules are housed in the first section, while the suppression host, the water-cooled unit, and the junction box are housed in the second section, all adjacent to the battery modules. The water-cooled unit directs coolant into the inlet of each battery module. After the coolant dissipates heat from the battery module, it flows out from the outlet of the battery module and back into the water-cooled unit, completing the coolant circulation. This heat dissipation method cannot guarantee that the coolant is evenly distributed in each battery module. Uneven temperature will accelerate the aging process of the battery module and may lead to a decline in battery performance, thereby shortening the service life of the battery module.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fully submersible liquid-cooled integrated energy storage cabinet includes an inner shell with an opening at the top, an inner frame disposed within the inner shell, and a battery module cluster disposed within the inner frame. The inner frame includes a first inner frame body and a second inner frame body, which are disposed opposite to each other. A water inlet is provided at the top of the first inner frame body, and a plurality of water holes are provided on the opposite side of both the first inner frame body and the second inner frame body. A water outlet is provided at the top of the second inner frame body.

[0008] As a further embodiment of this utility model, the inner shell includes an inner liner plate and a bottom liner plate that covers the lower opening of the inner liner plate.

[0009] As a further embodiment of this utility model, the inner frame further includes a plurality of horizontal flat tubes disposed between the first inner frame body and the second inner frame body on the same side.

Example

[0033] like Figure 1-4As shown, this application discloses a fully submersible liquid-cooled integrated energy storage cabinet, including an inner shell 30 with an open top, an inner frame 10 disposed within the inner shell 30, and a battery module cluster 20 disposed within the inner frame 10. The inner frame 10 includes a first inner frame body 11 and a second inner frame body 12, which are disposed opposite to each other. A water inlet 114 is provided at the top of the first inner frame body 11, and several water holes are provided on the opposite sides of both the first inner frame body 11 and the second inner frame body 12. A water outlet 124 is provided at the top of the inner frame body 12. Through the above structural design, the coolant enters the first inner frame body from the water inlet and fills the inner shell through the water hole, thereby immersing the battery module in the coolant. Therefore, the coolant can quickly absorb and disperse the heat generated by the battery module into the entire liquid environment. Then, the heat is discharged and reduced through heat exchange at the water outlet of the second inner frame body, thereby achieving the purpose of cooling and precise temperature control of the battery module, ensuring the consistency of temperature difference between battery modules, and effectively extending the battery's service life.

[0034] Specifically, the inner housing 30 includes an inner liner plate 31 and a bottom liner plate 32 that covers the lower opening of the inner liner plate 31. The upper opening of the inner housing 30 is covered by a top cover 33. Through the above structural design, the battery module is completely immersed in the inner housing, forming a closed and uniform cooling circulation space.

[0035] Specifically, a sealing ring 34 is provided between the edge of the opening on the inner shell 30 and the top cover. Through the above structural design, the sealing ring can effectively prevent coolant from leaking from the gap between the top cover and the inner shell, ensuring the sealing of the container.

[0036] Specifically, the inner frame 10 further includes a plurality of horizontal flat tubes 13 disposed between the first inner frame body 11 and the second inner frame body 12 on the same side. The first inner frame body 11 includes two first support columns 111 and a first square tube 112 disposed between the two first support columns 111. The two first support columns 111 and the first square tube 112 are interconnected by a plurality of first horizontal flat tubes 113. A water inlet 114 is provided at the top of the first square tube. A plurality of water holes are provided on both the first square tube 112 and the first horizontal tube 113. The second inner frame body 12 includes two second support columns 121 and a horizontal flat tube 113 disposed between the two second support columns 111 and the second inner frame body 12. The second square tube 122 between the columns 121, the two second support columns 121 and the second square tube 122 are interconnected by a number of second horizontal square tubes 123, and the top of the second square tube 122 is provided with a water outlet 124. Both the second square tube 122 and the second horizontal square tube 123 are provided with a number of water holes. Through the above structural design, the coolant enters the first inner frame body from the water inlet 114, and then enters the inner shell from the multiple water holes on the first inner frame body, so that the entire inner shell can be quickly filled. The water in the inner shell then enters the second inner frame body from the multiple water holes on the second inner frame body, which also facilitates the discharge of the coolant that absorbs the heat generated by the battery module from the water outlet.

[0037] Specifically, the four corners of the top of the inner frame 10 are fixedly connected to the corresponding four corners of the battery module cluster 20 by means of fasteners 40. The battery module cluster 20 includes a battery module cluster frame 21 and a plurality of battery modules installed in the battery module cluster frame 21. In specific implementation, the two first support columns 111 and the two second support columns 121 of the inner frame 10 are fixedly connected to the four corners of the battery module cluster frame 21 by means of fasteners 40.

[0038] Specifically, an outer frame 50 is provided outside the inner frame 10, the inner frame 10 is mounted on the base 14, and a bottom bracket 15 is provided between the inner frame 10 and the base 14.

[0039] As a further embodiment of this utility model, a lifting ring 23 is provided on the top of the battery module cluster 20. The lifting ring 23 includes a square frame and lifting lugs provided at the four corners of the frame, thereby facilitating the lifting and installation of the battery module cluster.

[0040] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, good temperature uniformity, and long lifespan.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
