Each exhaust fan is arranged in sequence along the vertical direction of the housing and bearing assembly and can operate independently to form different wind forces and air flow paths.

[0021] The auxiliary liquid cooling components include:

[0022] The liquid cooling coil is installed in the housing and support assembly and is connected to the coolant circulation equipment through pipelines. It is located above the energy storage assembly and is used to cool the energy storage assembly and the air inside the housing and support assembly.

[0023] In one embodiment of this utility model, a set of reinforcing ribs is provided at the bottom of the housing shell to structurally strengthen the bottom of the housing shell.

[0024] The advantages of this utility model are:

[0025] This containerized energy storage system combines an air intake component, an air exhaust component, and an auxiliary liquid cooling component to form a multi-layered heat dissipation mechanism. The air intake component introduces cool outside air to initially cool the energy storage components, while the air exhaust component uses exhaust fans to expel hot air, accelerating heat dissipation. The auxiliary liquid cooling component directly cools the energy storage components through liquid cooling coils, and the coolant circulation equipment ensures continuous flow of coolant, thereby removing a large amount of heat. The combination of air cooling and liquid cooling methods greatly improves heat dissipation efficiency. Each storage cabinet is installed in the housing component through a detachable connection structure, allowing the number of energy storage cells to be increased or decreased according to actual needs. Each liquid cooling module can operate independently to cool the energy storage cells within the storage cabinet, improving the system's flexibility and reliability. Attached Figure Description
