Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, and in particular to an energy storage liquid-cooled cabinet based on a dual-pump liquid-cooled host. Background Technology

[0002] An energy storage cabinet is an energy storage power station that uses batteries to store electrical energy. It typically consists of battery packs, DC / AC converters, high-voltage boxes, and other components. Energy storage cabinets are mainly used for peak-valley balancing of power grids, backup power for generator sets, wind and solar power smoothing, and emergency power for microgrids. They are one of the key pieces of equipment for the development and construction of smart grids.

[0003] Chinese invention patent application CN115775933A discloses an air-cooled energy storage cabinet, which includes a cabinet body, a cabinet door, and a heat dissipation mechanism. The cabinet body contains multiple rows of spaced-apart energy storage battery packs, forming multiple gaps. The cabinet door is rotatably connected to the cabinet body to open or close the cabinet. The heat dissipation mechanism includes an air conditioner, a central air duct group, multiple branch air ducts, and multiple longitudinal air ducts. The central air duct group is connected to the air outlet of the air conditioner, and the multiple branch air ducts are all connected to the central air duct group. The multiple longitudinal air ducts are respectively connected to the multiple branch air ducts, and the multiple longitudinal air ducts are respectively arranged in the multiple gaps. Each longitudinal air duct has a heat dissipation vent facing the energy storage battery pack. This air-cooled energy storage cabinet uses air cooling. Because air has poor heat capacity and thermal conductivity, a larger volume of airflow is required to remove the same amount of heat. This usually means higher fan speeds or more fans, which may result in lower energy efficiency. At the same time, because air has poor thermal conductivity, air-cooled systems usually require a large heat dissipation area, which requires sufficient internal space to install these heat dissipation components, resulting in a large space requirement. In addition, high-speed fans may be required for effective heat dissipation, which will generate more noise.

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

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. It should be pointed out that all accompanying drawings are exemplary representations. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0043] like Figure 1-7 As shown, this application discloses an energy storage liquid cooling cabinet based on a dual-pump liquid cooling host, including a cabinet body 10 and a cabinet door 20 hinged to the cabinet body 10 and used to control the opening and closing of the cabinet body; in this embodiment, the cabinet door 20 adopts a passive door lock, and the cabinet door can only be opened when the key is authorized.

[0044] The cabinet 10 is provided with a first accommodating space 11, a second accommodating space 12 and a third accommodating space 13 from top to bottom. The first accommodating space 11 is provided with a number of battery packs 30. The second accommodating space 12 is provided with an energy storage inverter 40 and a high voltage box 50. The third accommodating space 13 is provided with a dual-pump liquid cooling host 60.

[0045] The dual-pump liquid cooling unit 60 includes a first-pump liquid cooling unit and a second-pump liquid cooling unit.

[0046] The water outlet of the first pump liquid cooling host is connected to the water inlet of each of the battery packs 30 through the first water inlet pipe 61, and the water outlet of each of the battery packs 30 is connected to the water inlet of the first pump liquid cooling host through the first water outlet pipe 62.

[0047] The outlet of the second pump liquid cooling unit is connected to the inlet of the energy storage inverter 40 through the second inlet pipe 63, and the outlet of the energy storage inverter 40 is connected to the inlet of the second pump liquid cooling unit through the second outlet pipe 64.

[0048] The coolant flows into the battery pack and energy storage inverter through the inlet pipe under the action of the dual-pump liquid cooling unit. After cooling the battery pack and energy storage inverter, the coolant flows back to the dual-pump liquid cooling unit through the outlet pipe. This allows the coolant to repeatedly cool and dissipate heat from the energy storage inverter and battery pack under the action of the dual-pump liquid cooling unit. Since the heat capacity and thermal conductivity of liquid are much higher than those of air, the coolant more effectively removes heat, thus supporting higher performance output. Simultaneously, because it does not require a high-speed fan for effective heat dissipation, it significantly reduces operating noise levels, providing a quieter environment. Furthermore, since it does not require a large heat sink and multiple fans, this application is often more compact than air-cooled systems, making it ideal for applications with limited space. Therefore, this application not only has high heat dissipation efficiency and low noise but also saves space.

[0049] Specifically, the cabinet 10 is mounted on the base 70. Each of the four side walls of the base 70 is provided with two forklift holes 71 for easy handling. Each forklift hole 71 is covered with a sealing plate 72 to prevent rodents from entering the cabinet. Two fasteners 73 are also provided on the side wall of the base 70 opposite to the cabinet door 20 for fixing the base to the foundation.

[0050] Specifically, a pressure relief device 80 is embedded in the top plate of the cabinet 10. When the pressure inside the cabinet 10 reaches a set value, the pressure relief device 80 activates to release pressure. The pressure relief device 80 typically employs one of the following three types of pressure relief devices: Figure 4 As shown, this is a direct-detonation pressure relief device, which relieves pressure through direct detonation; as... Figure 5 As shown, this is a push-type pressure relief device, which uses four push rods on the left and right sides to open the top cover for pressure relief; as Figure 6 As shown, this is a side-push pressure relief device. Two push rods on either side push the top cover to one side to release pressure. Any of these pressure relief devices can achieve the purpose of releasing pressure from the inside to the outside, preventing further damage caused by excessive pressure due to thermal runaway within the cabinet. After pressure relief, fire hoses can be inserted into the cabinet through the pressure relief window to extinguish the fire and prevent further spread of the fire.

[0051] Specifically, each of the four corners of the top plate of the cabinet 10 is provided with a lifting ring 15 for lifting or unloading this application, and can be disassembled and stored when not in use.

[0052] Specifically, a support is provided inside the cabinet 10, and a first partition and a second partition are provided on the support. The first partition and the second partition divide the cabinet into a first accommodating space, a second accommodating space and a third accommodating space.

[0053] Specifically, the inner walls of the cabinet 10 are all covered with aluminum foil insulation and flame-retardant cotton to isolate the mutual interference of internal and external temperatures, thus achieving a dual fireproof purpose.

[0054] Specifically, the cabinet door 20 is provided with an air inlet louver 21 corresponding to the dual-pump liquid cooling host 60, and the cabinet body 10 is provided with an air outlet louver 16 corresponding to the dual-pump liquid cooling host 60 on the rear panel of the cabinet door 20. By setting the air inlet louver 21 and the air outlet louver 16, a good ventilation environment is provided for the dual-pump liquid cooling host, and at the same time, a certain degree of protection is provided for the equipment.

[0055] Specifically, a cabinet door opening limit device 22 is provided at the bottom of the side of the cabinet door 20 near the cabinet body 10. The cabinet door opening limit device 22 includes a mounting base and a U-shaped steel rod that is movably inserted into the mounting base. The cabinet body is provided with an insertion hole 110 that cooperates with the U-shaped steel rod near the cabinet door opening limit device. When the door is opened for maintenance, the two arms of the U-shaped steel rod are respectively inserted into the mounting base and the insertion hole 110 to support the cabinet door 20 and effectively prevent the safety hazards caused by the cabinet door 20 closing automatically.

[0056] Specifically, an access control sensor 18 is installed on the inner wall of the top plate of the cabinet 10 near the cabinet door. It is sensed or compressed when the cabinet door is normally closed. Specifically, a lighting lamp 19 is installed on the inner wall of the top plate of the cabinet 10 near the cabinet door 20. In this application, the lighting lamp 19 is turned on at night, which brings convenience for nighttime maintenance and repair.

[0057] Specifically, an operation indicator light 24 is provided in the middle of the side of the cabinet door 20 near the cabinet body 10; a water immersion sensor 14 is provided at the bottom of the inner wall of the side panel of the cabinet body 10 away from the cabinet door 20; an audible alarm 23 is provided at the top of the side of the cabinet door 20 near the cabinet body 10; a composite sensor 17 is provided on the inner wall of the top panel of the cabinet body 10 near the cabinet door 20, which has functions such as detecting smoke and flammable hazardous gases; when the cabinet door 20 is opened and the access control sensor 18 fails to detect or is compressed, when the composite sensor 17 detects an abnormality, or when the water immersion sensor 14 detects water immersion, an audible alarm is issued through the audible alarm 23 and a visual warning is provided through the operation indicator light 24, so as to monitor the safety of this application at any time.

[0058] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high heat dissipation efficiency, and low noise.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
