Description

Technical Field

[0001] The utility model relates to the technical field of energy storage equipment, in particular to a liquid-cooled energy storage cabinet. Background Art

[0002] The energy storage cabinet is the basic unit of energy storage equipment. The daily storage capacity of an energy storage cabinet reaches 5,500 degrees, which is like a large power bank, equivalent to the daily electricity consumption of more than 500 households. The main components of the energy storage cabinet are batteries, inverters, cables and other power electronic devices. Among them, batteries are more sensitive to temperature than other power electronic components. Therefore, the energy storage cabinet has higher requirements for the control of the temperature range and accuracy inside the cabinet.

[0003] Currently available energy storage cabinets generally use supply fans to dissipate heat inside the energy storage cabinet. When the temperature inside the energy storage cabinet is high, the supply fans cannot quickly dissipate heat inside the energy storage cabinet, resulting in a decrease in the heat dissipation efficiency of the energy storage cabinet and a shortened service life of the energy storage cabinet. At the same time, the heat dissipation temperature of the energy storage cabinet cannot be adjusted, resulting in the equipment inside the energy storage cabinet being unable to operate at a suitable temperature, which reduces the working efficiency of the energy storage cabinet.

[0004] According to a cabinet-type energy storage device provided by publication number: CN219678938U, the utility model includes a fixed base, a cabinet body is fixedly installed on the upper surface of the fixed base, a cabinet door is hinged in the middle of one end of the cabinet body, a fixed frame is fixedly installed at the bottom of one side of the outer surface of the cabinet body at the top of the fixed base, a placement groove is opened in the middle of the top of the fixed frame, a waterproof cloth is installed in the middle of the bottom end of the inner wall of the placement groove, a sliding frame is installed in the middle of the top of the waterproof cloth, a plurality of connecting ropes are fused on one side of the outer surface of the sliding frame, a hollow floating ball is installed on the edge of one end of the connecting rope, and a supporting mechanism is also provided on the upper surface of the fixed frame; the present application achieves the effect of waterproofing the bottom of the cabinet body by making the hollow floating ball rise synchronously with the accumulated water to drive the waterproof cloth to move and unfold, thereby solving the problem of rainwater entering the interior of the cabinet body and causing damage to the energy storage device, thereby improving the overall practicality and safety of the cabinet body when in use.

[0005] According to the energy storage cabinet described above, when the temperature inside the energy storage cabinet is high, the energy storage cabinet cannot quickly dissipate heat, resulting in a decrease in the heat dissipation efficiency of the energy storage cabinet and a reduction in the service life of the energy storage cabinet. At the same time, the heat dissipation temperature of the energy storage cabinet cannot be adjusted, resulting in the equipment in the energy storage cabinet being unable to operate at a suitable temperature, reducing the working efficiency of the energy storage cabinet. Therefore, we need to propose a liquid-cooled energy storage cabinet. Utility Model Content

[0025] A dustproof plate 12 is provided at a position on the outer surface of the cabinet 1 corresponding to the vent 3. The dustproof plate 12 is bolted to the side wall of the cabinet 1 by fasteners. The setting of the dustproof plate 12 facilitates the subsequent replacement of the dustproof plate 12 and prevents dust in the air from entering the inner cavity of the cabinet 1 through the vent 3.

The dust in the air can be filtered by setting the dust cover 53. The water pump 71 is started to provide driving force, and the water in the water tank 6 is pumped into the water pump pipe 72, and then the water is sent into the refrigerator 8 through the water supply hose 73 for cooling. The refrigerator 8 converts the air flowing inside the cabinet 1 into cold air, so that the cold air flows quickly inside the cabinet 1. Then the cold air drives the heat inside the cabinet 1 to be discharged from the vent 3, so as to achieve rapid heat dissipation of the cabinet 1. The stepper motor 111 is started to provide driving force to drive the first pulley 112 to rotate. The first pulley 112 is connected to the first pulley 112 through a belt drive. Then the second pulley 113 is driven to rotate, so that the first pulley 112 and the second pulley 113 synchronously drive the threaded rod 114 to rotate, and the rotation of the threaded rod 114 drives the lifting seat 115 to move through the threaded connection, so that the lifting seat 115 drives the lifting plate 9 to move, and the setting of the guide rod 13 prevents the threaded rod 114 from driving the lifting seat 115 to move, so that the lifting seat 115 can only move up and down on the surface of the threaded rod 114, so that the distance between the refrigerator 8 and the air supply assembly 5 can be adjusted, and the heat dissipation temperature of the energy storage cabinet can be adjusted by adjusting the distance between the refrigerator 8 and the air supply assembly 5, thereby increasing the working efficiency of the energy storage cabinet, improving the heat dissipation efficiency of the energy storage cabinet, and extending the service life of the energy storage cabinet.
