Description

Technical Field

[0001] The invention relates to the technical field of energy storage container cooling devices, and in particular to a liquid cooling plate assembly for a container. Background Art

[0002] At present, energy storage containers have become an important energy storage device, widely used in power systems, renewable energy power generation systems, and industrial and commercial fields. In energy storage containers, battery packs are the main energy storage units, and their operating temperature has an important impact on the performance and life of the energy storage system.

[0003] In current energy storage containers, in order to keep the battery pack within a suitable operating temperature range, a cooling device is usually required to control the temperature. However, traditional cooling devices have the following problems:

[0004] First, traditional cooling devices often require complex pipe arrangements and involve the installation of a large number of connectors and seals, which makes on-site assembly difficult, increases the complexity and time cost of engineering construction, and has limited flexibility in dealing with different battery pack layouts and orientation adjustments. The location and layout of the battery pack in the energy storage container may change due to system design requirements, and traditional devices are difficult to adapt to such changes.

[0005] Secondly, due to the presence of tube connections and seals, conventional cooling devices are prone to cooling medium leakage, which not only results in energy loss but may also threaten the operation of the battery pack. Summary of the invention

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, a liquid cooling plate assembly includes an upper plate 1 and a flow channel plate 2, the upper plate 1 is in a flat plate shape, the upper plate 1 and the flow channel plate 2 are connected to each other, and the flow channel plate 2 is provided with a flow channel 7 and a water nozzle 3;

[0033] The upper flat plate 1 is provided with a plurality of cross beams, and the flow channel plate 2 is provided with a plurality of reinforcing ribs.

[0034] In this embodiment, the upper plate 1 and the flow channel plate 2 are preferably fixed by riveting, and the gap is fully welded.

[0035] In this embodiment, Figure 2 and Figure 3As shown, the flow channel plate 2 is provided with a tortuous flow channel 7, and the water nozzle 3 includes a liquid inlet and a liquid outlet, and a loop is formed between the liquid inlet and the liquid outlet through the flow channel 7. The cooling medium flows in from the liquid inlet until it fills the entire cooling flow channel network, and then flows out from the liquid outlet. The cooling medium forms a circulation loop between the flow channel plate 2, the liquid inlet, and the liquid outlet, absorbing and diffusing the heat generated by the energy storage module, thereby realizing the heat dissipation of the energy storage module.

[0036] In this embodiment, the upper plate 1 is provided with a first module cross beam 4, a second module cross beam 5 and a third module cross beam 6 at a longitudinal interval. Energy storage modules are installed between the first module cross beam 4, the second module cross beam 5 and the third module cross beam 6. The number of cross beams varies according to the volume of energy storage modules installed, and is not limited to the number in this embodiment. The more energy storage modules are installed, the more cross beams are installed.

[0037] In this embodiment, Figure 2 As shown, in order to improve the overall strength and stability of the liquid cooling plate, the flow channel plate 2 is provided with a plurality of reinforcing ribs 13 at intervals in the longitudinal direction.

[0038] In order to further improve the overall strength, such as Figure 2 As shown, a plurality of reinforcing blocks 14 are installed on the reinforcing rib 13 .

[0039] In this embodiment, Figure 2 As shown, adjacent reinforcing ribs 13 are connected by connecting plates 15 .

[0040] In this embodiment, Figure 2 As shown, epoxy plates 12 are installed around the sides of the flow channel plate 2. By arranging the epoxy plates around the flow channel plate 2, the effects of insulation and flame retardancy can be achieved.

[0041] In this embodiment, the upper plate 1 and the flow channel plate 2 are both made of high-density steel-aluminum composite plates. Compared with the existing pure aluminum plates on the market, the use of high-density steel-aluminum composite plates has the following advantages:

[0042] High strength: Steel-aluminum composite panels are made of different metal layers stacked together, have high strength and rigidity, and can withstand large loads and moments.

[0043] Good corrosion resistance: The outer layer is usually made of materials with good corrosion resistance, such as stainless steel, aluminum alloy, etc., which can effectively resist corrosion and oxidation.

[0044] In this embodiment, Figure 2 As shown, the liquid cooling plate assembly is also provided with frames around it, including: a front frame 8, a left frame 9, a rear frame 10 and a right frame 11.
