Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage technology, specifically to a liquid-cooled energy storage cabinet. Background Technology
[0002] Liquid-cooled energy storage cabinets play a crucial role in the field of energy storage technology. Their liquid cooling system is a core element to ensure the safe and stable operation of energy storage systems. With the help of advanced liquid cooling technology, energy storage equipment can achieve efficient heat dissipation.
[0003] However, in practical applications, existing liquid-cooled energy storage cabinets are prone to leaks during long-term operation due to poor sealing or aging pipes, posing a serious threat to the operational safety of energy storage equipment. In the event of a refrigerant leak, current technology, with its low electrical enclosure protection rating (e.g., IP20), lacks effective protection against refrigerant leakage. Under pipeline pressure, the refrigerant may spray and splash throughout the electrical compartment, potentially causing short circuits in the electrical system or even catastrophic accidents such as fires and explosions, severely impacting the stability and safety of the energy storage system.
[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a liquid-cooled energy storage cabinet, which solves the existing problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid-cooled energy storage cabinet, comprising an energy storage cabinet body, wherein the energy storage cabinet body is provided with a relatively independent battery compartment body and an electrical compartment body, the battery compartment body and the electrical compartment body are connected only on both sides, the battery compartment body is provided with a plurality of evenly distributed battery boxes, the electrical compartment body is provided with a liquid cooler and an electrical box, a battery compartment insulation plate is provided between the battery compartment body and the electrical compartment body, and an electrical compartment insulation plate is provided between the liquid cooler and the electrical box;
[0007] The battery compartment is provided with a second side overflow port, and the electrical compartment is provided with a first side overflow port. The energy storage cabinet body is rotatably connected to a cabinet door. The bottom of the cabinet door is provided with multiple evenly distributed drainage holes. A louvered dustproof net is installed at the bottom of the cabinet door. A dustproof net strip is provided in the middle of the louvered dustproof net. A sealing strip is provided between the electrical compartment insulation board and the dustproof net strip.
[0008] As a preferred embodiment of this utility model, each of the multiple battery boxes is fixedly connected to a liquid cooling pipe on one side.
[0009] As a preferred technical solution of this utility model, an overflow port 2 is provided on the bottom of the battery compartment body near the liquid cooling pipe 1.
[0010] As a preferred embodiment of this utility model, a second liquid cooling pipe is fixedly connected to one side of the liquid cooler.
[0011] As a preferred technical solution of this utility model, the liquid cooler is provided with a side overflow port at one end near the liquid cooling pipe.
[0012] As a preferred technical solution of this utility model, a side baffle and a side baffle are provided on one side wall inside the electrical compartment body.
[0013] Compared with the prior art, the present invention provides a liquid-cooled energy storage cabinet, which has the following beneficial effects:
[0014] 1. This liquid-cooled energy storage cabinet, when refrigerant leakage occurs in the battery compartment, the sealing strip between the cabinet door and the cabinet body can prevent refrigerant from flowing out of the battery compartment from the gap in the cabinet door. The sealing strip between the battery compartment insulation board and other components can cause the refrigerant to collect on the upper surface of the insulation board and be discharged from the cabinet body through the battery compartment overflow port. When the liquid cooler pipe and interface leak, the sealing strip between the electrical compartment insulation board and the dustproof mesh pressure strip, as well as the corresponding overflow port and drainage hole design, can effectively guide the refrigerant to be discharged, preventing the refrigerant from entering the electrical box, greatly reducing the risk of electrical system short circuits, fires and explosions caused by refrigerant leakage, and ensuring the safe operation of the energy storage cabinet;
[0015] 2. This liquid-cooled energy storage cabinet features a layout where the battery compartment and electrical compartment are relatively independent and connected only on both sides. The reasonable arrangement of various components, such as the battery box, liquid cooler, and electrical box, along with corresponding insulation panels, overflow ports, baffles, and other components, makes the energy storage cabinet compact in structure and clearly defined in function. This facilitates installation, maintenance, and management, and improves the overall reliability and stability of the energy storage cabinet. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] refer to Figure 1 , Figure 2 In this embodiment: a liquid-cooled energy storage cabinet includes an energy storage cabinet body 1. The energy storage cabinet body 1 has a relatively independent battery compartment body 17 and an electrical compartment body 18 inside. The battery compartment body 17 and the electrical compartment body 18 are connected only on both sides. The battery compartment body 17 is provided with a plurality of evenly distributed battery boxes 15. The electrical compartment body 18 is provided with a liquid cooler 4 and an electrical box 9. A battery compartment insulation plate 3 is provided between the battery compartment body 17 and the electrical compartment body 18. An electrical compartment insulation plate 5 is provided between the liquid cooler 4 and the electrical box 9.
[0023] Specifically, the battery compartment body 17 and the electrical compartment body 18 are relatively independent, which facilitates the separate treatment of leaked refrigerant and prevents the two from directly affecting each other. The battery compartment insulation plate 3 and the electrical compartment insulation plate 5 can collect and divert the leaked refrigerant.
[0024] refer to Figure 1 and Figure 3 In this embodiment, the battery compartment is provided with a second side overflow port 13, the electrical compartment is provided with a first side overflow port 11, the energy storage cabinet body 1 is rotatably connected to a cabinet door 2, the bottom of the cabinet door 2 is provided with multiple evenly distributed drainage holes 8, the lower part of the cabinet door 2 is installed with a louvered dustproof net 7, the middle of the louvered dustproof net 7 is provided with a dustproof net pressure strip 6, and a sealing strip is provided between the electrical compartment insulation board 5 and the dustproof net pressure strip 6.
[0025] Specifically, the function of side overflow port 2 13 and side overflow port 11 is to discharge the refrigerant leaked in the two areas outside the energy storage cabinet body 1. The drain hole 8 at the bottom of the cabinet door 2 is used to assist the side overflow port 11 in discharging the refrigerant. The louvered dustproof net 7 plays the role of diversion and dust prevention.
[0026] refer to Figure 1, Figure 2 and Figure 4 In this embodiment, a liquid cooling pipe 14 is fixedly connected to one side of each of the multiple battery boxes 15. A side overflow port 13 is provided on the bottom of the battery compartment body 17 near the side of the liquid cooling pipe 14. A liquid cooling pipe 16 is fixedly connected to one side of the liquid cooler 4. A side overflow port 11 is provided at the end of the liquid cooler 4 near the liquid cooling pipe 16. A side baffle 10 and a side baffle 12 are provided on one side wall inside the electrical compartment body 18.
[0027] Specifically, side baffle 10 and side baffle 212 are used to divert leaked refrigerant so that it can be discharged through side overflow port 11 and side overflow port 213.
[0028] The working principle and usage process of this utility model are as follows: When refrigerant leakage occurs in the battery compartment, firstly, the sealing strip between the cabinet door 2 and the energy storage cabinet body 1 plays a sealing role, effectively preventing the refrigerant from flowing out of the battery compartment from the gap between the cabinet door 2 and the cabinet body. At this time, the refrigerant splashes and flows down along the outer surface of the battery pack, the inner surface of the cabinet door 2, and the side baffle of the battery compartment (not shown in the figure). Since there are sealing strips between the battery compartment insulation plate 3 and the intercom beam, and between the battery compartment insulation plate 3 and the battery box 15, these sealing strips play a good sealing and guiding role, allowing the refrigerant to collect on the upper surface of the battery compartment insulation plate 3. As the leakage increases, when it reaches a certain level, the refrigerant will flow through the side overflow port 13 near the liquid cooling pipe 14 at the bottom of the battery compartment to the guide port at the bottom of the energy storage cabinet (not shown in the figure), and then be discharged from the cabinet. When refrigerant leaks from the pipes and interfaces of the liquid chiller 4, the flow of refrigerant is restricted and guided because the liquid chiller 4 is separated from the electrical box 9 by the electrical compartment insulation board 5, and a sealing strip is installed between the electrical compartment insulation board 5 and the dustproof mesh strip 6 at the bottom of the lower cabinet door 2. Part of the refrigerant will flow to the upper part of the electrical compartment insulation board 5, and then along the side overflow port 11 located near the liquid chiller 4 near the liquid cooling pipe 16 to the leak port at the bottom of the energy storage cabinet, thus being discharged from the cabinet. Another part of the refrigerant will flow along the dustproof mesh and louvered dustproof mesh 7 to the multiple evenly distributed drain holes 8 at the bottom of the cabinet door 2, thus being discharged from the cabinet. This design effectively prevents refrigerant from entering the electrical box 9, ensuring the normal operation of the electrical system inside the electrical box 9 and guaranteeing the operational safety of the entire energy storage cabinet.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
