Description

Technical Field

[0001] The utility model relates to the technical field of energy storage cabinets, in particular to an air-cooled energy storage cabinet. Background Art

[0002] The energy storage cabinet is the basic unit of energy storage equipment. Multiple battery packs are installed in the upper and lower layers of the energy storage cabinet. The energy storage cabinet has a large storage capacity and generates high heat. In order to ensure the normal use of the energy storage cabinet, a heat dissipation structure must be configured to reduce the temperature inside the cabinet.

[0003] When traditional energy storage cabinets dissipate heat, they generally blow cold air upward from the bottom of the energy storage cabinet to the battery pack shell to achieve the purpose of cooling the battery. The main structure of the battery pack includes a shell and a battery. The battery is installed in the shell. The shell is equipped with circuit boards, fans and other devices. The fan blows the hot air in the shell out, and at the same time, the cold air outside the shell enters the shell under the action of negative pressure. This cycle is repeated to cool the battery. Since traditional energy storage cabinets use a heat dissipation method of blowing cold air from the bottom of the cabinet upward, although it can take away the heat in the cabinet to a certain extent, the higher the air temperature is, the poorer the heat dissipation effect is, and the temperature uniformity of the battery pack in the energy storage cabinet is difficult to be effectively guaranteed. Therefore, how to design energy storage cabinets? The heat dissipation structure of the cabinet has received extensive attention. In the prior art, such as patent CN220544078U, a heat dissipation energy storage cabinet is disclosed, which discloses that an exhaust duct is connected between the air conditioner and the air duct, the inlet of the exhaust duct is small and the outlet is large, and multiple second fans change the wind direction and flow rate of the cold air so that the cold air blows upward to the front cover plate of the shell of each battery pack. The first fans in the battery packs placed on the upper and lower adjacent layers of the cargo rack are installed in opposite directions, and a circulating heat dissipation method combining suction and exhaust is adopted, so that multiple air circulations are formed in the energy storage cabinet, but the air ducts do not correspond to the battery packs one by one, which is not convenient for ensuring that each battery pack in the energy storage cabinet can evenly distribute the air conditioning wind.

After the cold air flow reaches the plug box 4 to cool the energy storage battery, under the action of the centrifugal fan 41, the air flow returns to the air conditioner 2 through the return air duct 5.

[0034] When in use, a cold air flow is blown out from the air outlet of the air conditioner 2. After passing through the air inlet duct 3, the cold air flow is diverted into each guide air duct 31 in the diversion channel 30.
