Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage cabinets, and more specifically, relates to an air-cooled commercial energy storage cabinet. Background Art

[0002] An energy storage cabinet is a device that stores electrical energy. It typically consists of a battery pack, an inverter, and a control chip. It stores electrical energy and releases it when needed. Energy storage cabinets allow users to charge during low-cost periods and discharge it during peak periods to supply industrial and commercial users, reducing electricity costs while ensuring stable power supply.

[0003] When the energy storage cabinet is supplying power, the battery module will generate a large amount of heat energy. If the heat energy cannot be effectively dissipated, the internal temperature of the energy storage cabinet will rise sharply, affecting the normal use of the energy storage cabinet and even causing a fire.

[0004] Existing energy storage cabinets simply use heat exchangers or cabinet air conditioners for heat dissipation. When the heat load is high, the heat exchanger or air conditioner has the disadvantages of being large in size, incomplete and uneven heat dissipation, difficult installation and arrangement, and high cost. Conventional air ducts or no air ducts will cause excessive cold air loss, insufficient control and conduction of the cold air, and poor heat dissipation effect. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide an air-cooled commercial energy storage cabinet, which can achieve uniform heat dissipation of the energy storage cabinet, isolate the battery pack and control components, improve the heat dissipation capacity of the energy storage cabinet, and make the heat dissipation area more uniform.

[0006] The present invention provides an air-cooled commercial energy storage cabinet comprising a housing, a heat dissipation assembly, a battery assembly, and a control assembly. The heat dissipation assembly, battery assembly, and control assembly are all disposed within the internal chamber of the housing. The battery assembly comprises a plurality of battery packs arranged in longitudinal rows and at intervals. The heat dissipation assembly includes an air conditioner and a plurality of ventilation ducts. The air conditioner is disposed above the topmost battery pack. A plurality of ventilation ducts are disposed in the spaces between the battery packs. The control assembly is disposed on one side of the battery assembly, and the control assembly and battery assembly are each disposed in a separate cabinet.

[0007] As a further improvement to the present invention, the battery assembly includes a battery rack and L-shaped baffles. The battery rack comprises a plurality of spaced-apart frames. The lower ends of the frames are fixedly connected to the lower side of the housing, and a gap is maintained between the upper ends of the frames and the upper side of the housing to accommodate the air conditioner. A plurality of L-shaped baffles are fixedly mounted on the frames at equal intervals. L-shaped baffles are symmetrically arranged between adjacent frames to accommodate the battery packs.

[0008] As a further improvement of the present invention, the ventilation duct includes a first ventilation duct, a second ventilation duct, and a third ventilation duct. The first ventilation duct is disposed on the left side of the battery assembly. The second ventilation duct is disposed in the middle of the battery assembly. The third ventilation duct is disposed on the right side of the battery assembly. The first ventilation duct, the second ventilation duct, and the third ventilation duct are all connected to the air outlet of the air conditioner.

[0009] As a further improvement of the present invention, the heat dissipation assembly further includes a first vent, a second vent, and a third vent. The first vent is located at the upper left end of the housing. The third vent is located at the upper right end of the housing. A battery cabinet door is located on the front side of the housing. The third vent is located on the battery cabinet door and is located on the front side of the battery assembly.

[0010] As a further improvement of the present invention, the heat dissipation assembly further comprises a heat dissipation fan. The heat dissipation fan is arranged on the rear side of the cabinet where the control assembly is located, and the heat dissipation fan is located on the rear side surface of the shell.

[0011] As a further improvement of the present invention, the heat dissipation assembly further includes a heat dissipation window. The heat dissipation window is fixedly arranged on the rear side of the housing. A heat dissipation window is correspondingly arranged on the rear side of each heat dissipation fan.

[0012] As a further improvement of the present invention, the control component includes a PCS system and an inverter. The inverter is arranged on the lower side of the PCS system and is electrically connected to the PCS system.

[0013] As a further improvement to the present invention, a circulation assembly is also included. The circulation assembly includes a translation guide rail, a drainage fan, a sliding seat, and a drive motor. The translation guide rail is vertically arranged between the housings, with the upper end of the translation guide rail fixedly connected to the upper side of the housing, and the lower end of the translation guide rail fixedly connected to the lower side of the housing. The sliding seat is connected to the translation guide rail for vertical sliding. The drive motor is arranged on one side of the translation guide rail, and the output end of the drive motor is connected to the sliding seat. The drainage fan is fixedly connected to the sliding seat to move up and down with the sliding seat.

[0014] As a further improvement of the present invention, the circulation components are symmetrically arranged in the first ventilation channel and the third ventilation channel respectively.

[0015] As a further improvement of the present invention, it further comprises a suspension ring. A plurality of suspension rings are fixedly arranged on the upper side of the shell.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By setting up heat dissipation components and mobile components, different air ducts form airflow circulation loops with different channels. The mobile guide rail drives the drainage fan to move up and down, promoting air circulation around the batteries away from the air-conditioned area, so that the heat dissipation level is close to that of the batteries near the air-conditioned area. This can achieve uniform heat dissipation of the energy storage cabinet, isolate the battery pack and control components, improve the heat dissipation capacity of the energy storage cabinet, and make the heat dissipation area more uniform.
