Energy storage cabinets are a type of equipment that integrates energy storage devices and power management systems. They are mainly used to store electrical energy and release it when needed. The concept of energy storage cabinets is to centrally store electrical energy so that it can be used to supply power during peak hours of electricity demand or in emergencies. It is mainly composed of batteries, inverters and control systems. Batteries are the core components of energy storage cabinets, which can convert electrical energy into chemical energy and store it. The function of the inverter is to convert the stored DC power into AC power for use by various electrical equipment. The control system plays a role in management, optimizing energy utilization and protecting battery life.
[0003] However, the existing electrical cabinets for charging energy storage batteries still have the following problems during use:
[0004] When the existing electrical cabinet is in use, it is necessary to use a cooling fan to dissipate the heat of each energy storage battery being charged in the electrical cabinet. Since the charging room in the electrical cabinet is often empty because the energy storage batteries are taken out for use, cold air still flows in the empty charging room, which makes the flow range of the cold air blown by the cooling fan inside the electrical cabinet larger. At the same time, the cobwebs and dust inside the electrical cabinet can easily block the connecting holes on the charging room, reducing the heat dissipation effect of the energy storage batteries. Therefore, it is very necessary to use a cooling system involving an energy storage battery plug-in box and an electrical cabinet in the existing electrical cabinet field. Utility Model Content
[0005] In order to make up for the deficiencies of the prior art, the charging room in the existing electrical cabinet is often left vacant because the energy storage battery is taken out for use, and cold air still flows in the vacant charging room, which increases the flow range of the cold air blown by the cooling fan inside the electrical cabinet. At the same time, cobwebs and dust inside the electrical cabinet easily block the connecting holes on the charging room, reducing the heat dissipation effect of the energy storage battery. The utility model proposes a cooling system for an energy storage battery plug-in box and an electrical cabinet.
