[0018] like Figure 1-2 As shown, the liquid cooling pipe arrangement structure of the liquid-cooled energy storage cabinet includes a cabinet bracket 9, a liquid cooling box 8, a first liquid cooling pipeline 1 and a second liquid cooling pipeline 2. The first liquid cooling pipeline 1 and the second liquid cooling pipeline 2 are both connected to the liquid cooling box 8 and are symmetrically arranged on the left and right sides of the cabinet bracket 9. A plurality of hoses 4 connected to the battery pack are arranged on the inner side of the cabinet bracket 9. A drain port 3 connected to the first liquid cooling pipeline 1 and the second liquid cooling pipeline 2 is arranged on the outer side of the bottom of the cabinet bracket 9. A hard pipe 5 connected to the first liquid cooling pipeline 1 is arranged on the inner side of the bottom of the cabinet bracket 9. It can be understood that compared with the distributed double-sided liquid cooling system of a power battery system disclosed in the Chinese invention patent with patent application number 201610795994.X, the application environment of the utility model is different. The symmetrical design of the pipeline on both sides is used in the outdoor energy storage cabinet. The pipeline adopts a combination of hard pipes and soft pipes. The hard pipe pipeline makes full use of the space of the cabinet and is distributed on both sides of the cabinet bracket. At the same time, when the internal equipment position is designed, it is adjusted according to the direction of the pipeline to ensure the straight path of the pipeline, reduce bends, and indirectly save the cost of pipeline laying.

[0019] Specifically, the cabinet bracket is provided with a plurality of battery pack cavities 6 for installing the battery pack, and each of the battery pack cavities 6 is correspondingly provided with two of the hoses 4; the hoses 4 are respectively connected to the first liquid cooling pipeline 1 and the second liquid cooling pipeline 2; the inner side of the upper end of the cabinet bracket 9 is provided with a liquid cooling box cavity 7 for installing the liquid cooling box 8, and the inner side of the bottom of the cabinet bracket 9 is provided with a PCS module cavity 10 for installing the PCS module; the outer side of the cabinet bracket 9 is provided with a sheet metal plate 11, and the first liquid cooling pipeline 1 and the second liquid cooling pipeline 2 are located in the gap between the sheet metal plate 11 and the cabinet bracket 9, and the liquid cooling pipes are arranged by utilizing the gap between the cabinet and the outer appearance sheet metal, thereby reducing the fixing brackets of the liquid cooling pipes and directly fixing them on the fixing brackets of the battery pack, thereby saving the pipe laying space of the liquid cooling pipeline of the cabinet and not affecting the width of the cabinet; the battery pack cavity 6 is provided with a battery pack support plate 12 for supporting the battery pack.

[0020] It can be understood that the utility model has a reasonable design and a unique structure. The pipelines are divided into a first liquid cooling pipeline 1 and a second liquid cooling pipeline 2. The first liquid cooling pipeline 1 and the second liquid cooling pipeline 2 basically achieve a left-right symmetrical layout. The connection part between the pipeline and the liquid cooling box 8 adopts a direct outward form and is placed on both sides of the cabinet bracket 9; the hose 4 is connected to the battery pack. Since the hose 4 is relatively soft, it can be pulled out from the inside and connected to the battery pack after the battery pack is installed. This form of pipe layout will not affect the disassembly and maintenance of the battery pack; the drain outlet 3 of the liquid cooling pipeline drains water at the bottom of both sides, which is also convenient for water outflow and does not affect other electrical parts; the hard pipe 5 also adopts the form of a universal hard pipe to adjust the position of the PCS module to ensure that the liquid cooling pipeline can be directly connected to the main pipeline without making bends, saving the cost of pipe layout.
