Description

Technical Field

[0001] This application relates to the technical field of energy storage cabinets, and particularly to a liquid-cooled energy storage cabinet. Background Art

[0002] In existing liquid-cooled energy storage cabinets, although the self-protection level of modules such as PCS is above IP55, the setting of a high protection level results in high costs. To reduce costs, a lower protection level may be selected. In this case, condensate will be generated during the long-term operation of the liquid-cooling unit. If the condensate cannot be effectively collected at the bottom, water accumulation will occur. The water accumulation may not only cause cabinet corrosion but also pose a safety hazard to other modules with a lower protection level, affecting the normal operation and service life of the entire energy storage system.

[0003] Based on this, this application provides a liquid-cooled energy storage cabinet to solve the above problems. Utility Model Content

[0004] The purpose of this application is to solve the problem in the prior art that the condensate of the liquid-cooling unit in the liquid-cooled energy storage cabinet affects the normal operation and service life of the entire energy storage system, and to propose a liquid-cooled energy storage cabinet.

[0005] To achieve the above purpose, this application adopts the following technical solutions:

[0007] The condensate drainage device includes a water receiving tray and a water guiding pipeline. The water receiving tray is arranged between the bottom of the liquid-cooling unit and the second partition member; one end of the water guiding pipeline is connected to the water receiving tray, and the other end is connected to the floor drain; when condensate flows out from the bottom of the liquid-cooling unit, the water receiving tray is used to hold the condensate and discharge it to the drainage pipeline through the water guiding pipeline from the floor drain.

[0008] The beneficial effect of this technical solution is that through an effective condensate collection and discharge mechanism, the accumulation of condensate in the cabinet is avoided, the potential safety risks caused by water accumulation are reduced, and the condensate of the liquid-cooling unit in the liquid-cooled energy storage cabinet is prevented from affecting the normal operation and service life of the entire energy storage system. While achieving efficient drainage, a water receiving tray and a water guiding pipeline with simple structures and low costs are adopted, which has good economic efficiency.

[0013] The beneficial effect of this technical solution is that by setting drain holes at the corners of the water receiving tray, the flow rate of condensate can be increased, the residence time on the water receiving tray can be reduced, thereby improving the overall drainage efficiency. Since the condensate can be discharged from the water receiving tray faster, the water accumulation on the water receiving tray is reduced, and the potential corrosion or safety risks caused by water accumulation are lowered. Selecting to set the drain holes at the corners of the water receiving tray far from the left compartment optimizes the space layout.

[0014] In some possible implementation manners, support columns are provided on one side of the second right compartment far from the left compartment, and the water guiding pipeline closely adheres to the support columns and is introduced from the water receiving tray into the floor drain of the bottom plate.

The support columns not only provide additional support, but also serve as a fixed path for the water guiding pipeline, helping to maintain the stability of the liquid cooling energy storage cabinet. Since the water guiding pipeline closely adheres to the support columns, it can be more easily located and accessed during maintenance and inspection, simplifying the maintenance work. The above layout method can reduce the interference of the water guiding pipeline to other components or cables.

[0016] In some possible implementation manners, a plurality of positioning components are further provided, and the positioning components are used to fix the water guiding pipeline on the support columns.

[0017] The beneficial effects of this technical solution are as follows: The use of the positioning component improves the stability of the water diversion pipeline, prevents the pipeline from loosening or falling off due to vibration or thermal expansion, and ensures the long-term stable operation of the condensate drainage device. The fixing structure reduces the wear of the pipeline caused by long-term vibration and extends the service life of the water diversion pipeline. Ensuring the fixation of the water diversion pipeline can prevent potential safety risks caused by accidental detachment of the pipeline.

[0018] In some possible implementation manners, the part of the water diversion pipeline close to the support column is a square pipe or a round pipe, the positioning component is a cable tie, and a plurality of cable tie holes are provided on the support column for the cable tie to pass through and fix the round pipe part of the water diversion pipeline.

[0019] The beneficial effects of this technical solution are as follows: The cable tie can be adjusted according to the diameter of the water diversion pipeline, providing a flexible fixing solution.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0032] See Figures 1 to 3 , the embodiments of the present application provide a liquid-cooled energy storage cabinet, including a cabinet body 10 and a condensate drainage device 20; a vertically arranged first partition member 11 is provided inside the cabinet body 10, dividing the cabinet body 10 into a left compartment 12 and a right compartment 13, and the left compartment 12 is used to place battery packs for storing electric energy; a horizontally arranged second partition member 14 is provided inside the right compartment, dividing the right compartment 13 into a first right compartment and a second right compartment from top to bottom, and the first right compartment is used to place a liquid cooling unit 15; a floor drain 16 is provided on the bottom plate of the second right compartment, and the floor drain 16 is used to communicate with a drainage channel outside the cabinet body 10;

[0033] The condensate drainage device 20 includes a water receiving tray 21 and a water guiding pipeline 22, the water receiving tray 21 is arranged between the bottom of the liquid cooling unit 15 and the second partition member 14; one end of the water guiding pipeline 22 communicates with the water receiving tray 21, and the other end communicates with the floor drain 16; when condensate water flows out from the bottom of the liquid cooling unit 15, the water receiving tray 21 is used to hold the condensate water and discharge it to the drainage pipeline through the water guiding pipeline 22 from the floor drain 16. Among them, the first partition member 11 and the second partition member 14 mentioned below can be a partition board or a partition frame respectively.

[0034] Inside the liquid-cooled energy storage cabinet, the space is divided by the first partition member 11 and the second partition member 14 to form a left compartment 12, a first right compartment, and a second right compartment. The left compartment 12 is used to store battery packs, the first right compartment houses the liquid-cooling unit 15, and the bottom plate of the second right compartment is provided with a floor drain 16. During the operation of the liquid-cooling unit 15, due to the heat exchange when the coolant contacts the surface of the equipment during the liquid-cooling process, condensate will be generated. A water receiving tray 21 is arranged between the bottom of the liquid-cooling unit 15 and the second partition member 14, and is used to collect the condensate flowing out from the bottom of the liquid-cooling unit 15. One end of a water guiding pipeline 22 is connected to the water receiving tray 21, and the other end is connected to the floor drain 16. When the condensate flows into the water receiving tray 21, it is guided to the floor drain 16 through the water guiding pipeline 22. The floor drain 16 is connected to the drainage channel outside the cabinet body 10, so that the condensate can be smoothly discharged from the energy storage cabinet to prevent it from accumulating inside the cabinet. The first right compartment is used to place the liquid-cooling unit. The liquid-cooling unit can be fixed at an appropriate position in the first right compartment by bolts, brackets or other fixing devices, and a space for arranging the water receiving tray 21 is left between the bottom of the liquid-cooling unit and the second partition member 14.

[0035] Thus, through an effective condensate collection and discharge mechanism, the accumulation of condensate inside the cabinet body 10 is avoided, the potential safety risks caused by water accumulation are reduced, and the normal operation and service life of the entire energy storage system are prevented from being affected by the condensate of the liquid-cooling unit 15 of the liquid-cooled energy storage cabinet. While achieving efficient drainage, the water receiving tray 21 and the water guiding pipeline 22 with simple structures and low costs are adopted, which has good economy.

[0036] In summary, through the structural design of condensate collection and discharge, this technical solution avoids the problem of condensate accumulation inside the cabinet during the operation of the liquid-cooling unit 15, and improves the safety, durability and economy of the energy storage cabinet.

[0037] In one embodiment, at least one corner of the water receiving tray 21 away from the left compartment 12 is provided with a drain hole, and one end of the water guiding pipeline 22 communicates with the water receiving tray 21 through the drain hole.

[0038] The water receiving tray 21 is arranged between the bottom of the liquid-cooling unit 15 and the second partition member 14, and at least one corner thereof away from the left compartment 12 is provided with a drain hole to allow the condensate to flow smoothly to the drain hole when flowing on the surface of the water receiving tray 21. In specific applications, the position of the drain hole of the water receiving tray 21 is lower than other positions. One end of the water guiding pipeline 22 is connected to the water receiving tray 21 through the drain hole, and the condensate can directly flow into the water guiding pipeline 22 through the drain hole, so as to achieve more effective collection and transmission. The condensate flows in the water guiding pipeline 22 and finally is discharged to the drainage channel outside the cabinet body 10 through the floor drain 16 to complete the entire drainage process.

[0039] Thus, by setting drainage holes at the corners of the water receiving tray 21, the flow rate of the condensed water can be increased, the residence time on the water receiving tray 21 can be reduced, thereby improving the overall drainage efficiency. Since the condensed water can be discharged from the water receiving tray 21 faster, the ponding on the water receiving tray 21 is reduced, and the potential corrosion or safety risks caused by the ponding are lowered. Selecting to set the drainage holes at the corners of the water receiving tray 21 far from the left compartment 12 optimizes the spatial layout.

[0040] In specific applications, the above design can be adjusted according to the sizes and shapes of different liquid cooling units 15 and energy storage cabinets to adapt to different application scenarios and requirements. Generally, the water receiving tray 21 matches the bottom shape of the liquid cooling unit 15.

[0041] In one embodiment, support columns are provided on one side of the second right compartment far from the left compartment 12, and the water guiding pipeline 22 closely adheres to the support columns and is introduced from the water receiving tray 21 into the floor drain 16 of the bottom plate.

[0042] The support columns are arranged on one side of the second right compartment far from the left compartment 12, which can increase the structural stability of the cabinet 10. The water guiding pipeline 22 is closely arranged along the support columns and is introduced from the water receiving tray 21 into the floor drain 16 of the bottom plate of the second right compartment.

[0043] Thus, by arranging the water guiding pipeline 22 closely along the support columns, the space of the second right compartment can be utilized more effectively, avoiding occupying extra space, while maintaining the compactness of the water guiding pipeline 22. The support columns not only provide additional support, but also serve as a fixed path for the water guiding pipeline 22, contributing to maintaining the stability of the liquid cooling energy storage cabinet. Since the water guiding pipeline 22 closely adheres to the support columns, it can be more easily located and accessed during maintenance and inspection, simplifying the maintenance work. The above layout method can reduce the interference of the water guiding pipeline 22 to other components or cables.

[0044] In one embodiment, a plurality of positioning components are further provided, and the positioning components are used to fix the water guiding pipeline 22 on the support columns.

[0045] A plurality of positioning components are installed on the support columns. The positioning components are, for example, fixing clips, snap rings or other forms of positioning structures. The water guiding pipeline 22 is fixed on the support columns through the positioning components to ensure its stable and correct position within the liquid cooling energy storage cabinet. The design of the positioning components ensures the fixed position of the water guiding pipeline 22 on the support columns, preventing pipeline displacement or bending caused by vibration or thermal expansion.

[0046] Thus, the use of the positioning component improves the stability of the water diversion pipeline 22, prevents the pipeline from loosening or falling off due to vibration or thermal expansion, and ensures the long-term stable operation of the condensate drainage device 20. The fixing structure reduces the wear of the pipeline caused by long-term vibration and extends the service life of the water diversion pipeline 22. Ensuring the fixation of the water diversion pipeline 22 can prevent potential safety risks caused by accidental detachment of the pipeline.

[0047] In one embodiment, the part of the water diversion pipeline 22 in contact with the support column is a square pipe or a round pipe, the positioning component is a cable tie, and a plurality of cable tie holes are provided on the support column for the cable tie to pass through and fix the round pipe part of the water diversion pipeline 22.

[0048] The water diversion pipeline 22 is in the form of a square pipe or a round pipe, and a suitable pipe type is selected according to actual needs and spatial layout. A plurality of cable tie holes are provided on the support column for the cable tie to pass through to fix the water diversion pipeline 22. The cable tie passes through the cable tie hole on the support column and then surrounds the water diversion pipeline 22. Especially when the water diversion pipeline 22 is a round pipe, the geometric shape of the round pipe is continuous and symmetrical, and no matter from which angle the cable tie surrounds, it can closely fit the pipe body, providing a uniform pressure distribution, making the fixing effect better. The combined use of the cable tie and the cable tie hole ensures the stability of the water diversion pipeline 22 on the support column and prevents the pipeline displacement caused by vibration or thermal expansion.

[0049] Thus, the cable tie can be adjusted according to the diameter of the water diversion pipeline 22, providing a flexible fixing solution. The cable tie can absorb part of the vibration, reduce the influence of vibration on the water diversion pipeline 22, and improve the reliability of the condensate drainage device 20.

[0050] In one embodiment, one end of the water diversion pipeline 22 is adhesively connected to the drain hole through a drain pipe with glue; or,

[0051] One end of the water diversion pipeline 22 is provided with an external thread joint, and the drain hole is provided with an internal thread joint, and the external thread joint is used for connecting the water diversion pipeline 22 to the internal thread joint of the drain hole.

[0052] It can be understood that one end of the water diversion pipeline 22 is connected to the drain hole through a drain pipe, and glue is used as an adhesive to ensure the sealing and stability of the connection. Specifically, the glue can be evenly applied to the connection end of the drain pipe and the edge of the drain hole, and then the drain pipe is aligned with the drain hole and fixed. After the glue dries, a sealed connection is formed. The condensate flows from the water receiving tray 21 into the drain pipe, passes through the connection joint bonded with glue, and smoothly flows to the floor drain 16 for discharge.

[0053] Alternatively, one end of the water inlet pipe 22 is provided with an external thread joint, and the drain hole is provided with an internal thread joint. The external thread joint is screwed into the internal thread joint to achieve a tight threaded connection. Specifically, clean the surfaces of the external thread joint and the internal thread joint to ensure no impurities, and then screw the external thread joint into the internal thread joint until it is tightly connected. The condensed water flows from the water receiving tray 21 into the water inlet pipe 22 and smoothly flows to the floor drain 16 through the threaded drain pipe for discharge.

[0054] Thus, on the one hand, using glue connection can form a good seal. The glue connection operation is simple, does not require complex tools or techniques, and is easy to implement; the glue connection allows a certain degree of displacement and angular adjustment to adapt to different installation requirements. On the other hand, the threaded connection provides good mechanical stability and can keep the connection from loosening even in a vibrating environment; the threaded connection allows for convenient disassembly and reinstallation, facilitating maintenance and replacement of the pipeline.

[0055] In one embodiment, front doors and rear doors are respectively provided on the front and rear sides of the right compartment 13, and one side of the water receiving tray 21 close to the front door and / or the rear door is a transparent plate.

[0056] One side of the water receiving tray 21 close to the front door and / or the rear door uses a transparent plate material, allowing the situation inside the water receiving tray 21 to be observed from outside the cabinet. Due to the presence of the transparent plate, the operator can observe the state of the water receiving tray 21, such as the accumulation of condensed water, through the transparent area of the front door and / or the rear door. The transparent plate design facilitates regular maintenance and inspection work, and the operator can quickly judge whether it is necessary to clean the water receiving tray 21 or check the drainage system. In a specific application, a suitable transparent plate material (such as polycarbonate plastic) can be selected to provide durability and impact resistance.

[0057] Thus, the transparent plate allows the operator to observe the condensed water situation of the water receiving tray 21 without directly contacting the water receiving tray 21, reducing the risk of electric shock. By quickly checking the water receiving tray 21 through the transparent plate, the inspection efficiency can be improved.

[0058] In one embodiment, the second right compartment is used to place the high-voltage box, and the left compartment 12 is also used to place the PCS (Power Conversion System). The high-voltage box contains high-voltage circuits and components for the power conversion or distribution of the energy storage system. Placing the high-voltage box in the second right compartment can isolate it from other components to improve safety and maintenance convenience. The left compartment 12 places the PCS (Power Conversion System), and the PCS is responsible for converting the direct current stored in the battery pack into alternating current or performing the reverse conversion. Placing the PCS in the left compartment 12 can make it close to the battery pack to optimize the power conversion path. The liquid cooling system is used to cool key components such as the high-voltage box and the PCS to keep their operating temperatures within a safe range. Through the design of the liquid-cooled energy storage cabinet, it is ensured that the coolant can effectively circulate and evenly cool each component.

[0059] Therefore, by placing different functional components in different compartments, a modular design can be achieved to facilitate component replacement and maintenance. The internal space of the energy storage cabinet can be maximized, while ensuring that there is enough space between components for heat dissipation and maintenance. At the same time, a reasonable space layout allows the condensate drainage device 20 to be set as far away from the PCS as possible, reducing electrical safety risks caused by leakage or overflow.

[0060] In one embodiment, a filter is provided at one end of the water supply pipe 22 close to the floor drain 16 , and / or a filter is provided at the floor drain 16 opening where the floor drain 16 is connected to the drainage channel.

[0061] A filter is provided at one end of the water supply pipe 22 close to the floor drain 16, or a filter is provided at the floor drain 16 opening where the floor drain 16 is connected to the drainage channel, to capture solid particles, impurities or other foreign matter that may enter the pipe, intercept foreign matter and prevent it from entering the drainage channel, thereby reducing blockage.

[0062] Therefore, through the filtering effect of the filter, the accumulation of pollutants inside the pipeline can be reduced and the cleaning cycle of the pipeline can be extended.
