[0040] As can be seen from the above description, the battery compartment 2 is equipped with an aerosol 27 and a pressure relief valve 28 to provide fire extinguishing and pressure relief protection against early thermal runaway. If thermal runaway becomes uncontrollable and spreads, the water fire extinguisher 29 on the back of the battery compartment 2 opens and injects water to control the runaway condition. Simultaneously, the explosion relief panel 291 on the top of the battery compartment 2 acts to rapidly relieve pressure from the battery compartment 2.

[0041] In an optional embodiment, a partition plate is provided between two adjacent liquid-cooled electrical boxes 22 , the partition plate is provided with a groove, and a drainage hole is provided in the groove.

[0042] From the above description, it can be seen that the partition plate of the battery compartment 2 is not a conventional flat partition, but is designed with a concave middle part and a drainage hole. When too much condensation water falls in the battery compartment 2, the condensation water can be collected and discharged.

[0043] In an optional embodiment, the inner wall of the battery compartment 2 is provided with thermal insulation cotton.

[0044] From the above description, it can be seen that the inner walls of the battery compartment 2 are all covered with thermal insulation cotton, which can provide a relatively constant temperature space environment for the battery compartment 2.

[0046] From the above description, it can be seen that the liquid cooling unit 31 is fixed with front and rear sealing plates, and hexagonal mesh holes are opened on the front and rear sealing plates, which is conducive to ventilation and heat dissipation of the liquid cooling unit 31.

[0047] Please refer to Figures 1 to 4 As shown, the first embodiment of the present invention is: a liquid-cooled energy storage integrated cabinet, including a cabinet body 1, with an overall size of length × width × height: 1500mmx1300mm×2050mm, and a battery compartment 2, a cooling unit compartment 3 and an equipment compartment 4 are provided in the cabinet body 1; the battery compartment 2 can meet IP55, the equipment compartment 4 can meet IP54, and the liquid cooling unit 31 compartment can meet IP20.

[0048] The battery compartment 2 is provided with a main control box 21 and five liquid-cooled electric boxes 22 arranged from top to bottom. The main control box 21 is located at the bottom and is connected in series with two or more liquid-cooled electric boxes 22.

[0049] The cooling unit compartment 3 is located below the battery compartment 2 and is provided with a liquid cooling unit 31. The liquid cooling unit 31 is respectively connected to two or more liquid cooling electric boxes 22.

[0050] An AC power distribution module 41 and a PCS 42 are provided in the equipment compartment 4 , and the AC power distribution module 41 , the PCS 42 and the main control box 21 are connected in sequence.

[0051] Equipment compartment 4 also houses a control box 43, which connects to the AC power distribution module 41 and PCS 42. This control box 43 primarily consists of communication and control components, including relays, fuses, ACDC, insulation detection boards, EMUs, switches, routers, and other electrical components. Equipment compartment 4 also houses a fire control unit module 44, to which this control box 43 connects. This unit primarily consists of a fire control unit and fire-related terminal blocks. The AC power distribution module 41 primarily consists of a circuit breaker 411, switches, an electric meter, a main distribution circuit breaker, and other electrical components, along with an AC busbar. Furthermore, space is reserved above PCS 42 in equipment compartment 4 for adding another PCS 42. If a customer requires higher power output, this can be achieved by simply modifying the AC power distribution module 41—that is, enlarging the AC busbar and replacing the circuit breaker 411—without affecting other modules. A circuit breaker 411 is located at the lower front of equipment compartment 4 to control the connection between the power grid and the energy storage cabinet. The top row houses common electrical components such as switches, meters, and a main distribution circuit breaker (MCB) (from right to left). Above this are the PCS 42 and UPS 47. The fire control unit module 44 is located in the space below the UPS 47. Below this is the control box 43 and EMU assembly 48, with the EMU assembly 48 mounted directly on the panel of the control box 43 to facilitate routine maintenance. The control box 43 is mounted on the AC distribution module 41 and secured to it by a front gasket. When maintenance is required on the electrical components within the box, the gasket can be removed and the control box 43 can be pulled out. Less frequently used electrical components, such as the switch, router, UPS 47 MCB, and water-cooling unit MCB, are located on the panel of the control box 43. At the rear of the equipment compartment 4, the PCS 42's air outlet is equipped with a separate hood assembly 421. This hood houses two fans that accelerate the exhaust of hot air from the PCS 42, allowing it to operate at higher ambient temperatures.

[0052] The cabinet 1 is equipped with a door 11 and a limit switch 12. The limit switch 12 is used to monitor the opening and closing of the door 11 and is connected to the control box 43. The equipment compartment 4 is equipped with a flood control 45 and an AC lightning arrester 46, both of which are connected to the control box 43. The battery compartment 2 is equipped with a smoke detector 23, a temperature detector 24, a combustible gas detector 25, and an audible and visual alarm 26, all of which are connected to the control box 43. The battery compartment 2 is also equipped with an aerosol 27, a pressure relief valve 28, a water fire extinguisher 29, and an explosion relief panel 291, all of which are connected to the control box 43. A partition plate is installed between adjacent liquid-cooled electrical boxes 22. The partition plate has a groove with drainage holes. The inner wall of the battery compartment 2 is covered with thermal insulation. The liquid cooling unit 31 is locked to the inner wall of the cooling unit cabin 3 through a sealing plate, and the sealing plate is provided with a heat dissipation mesh.

[0053] After the external AC power is connected from the circuit breaker 411, it is directly connected to the AC busbar, and then the AC busbar is connected to the AC port at the end of PCS42 through a wiring harness. The DC port at the end of PCS42 is connected to the output port on the right side of the front panel of the main control box 21 through a wiring harness. The input port on the left side of the main control box 21 is connected in series with the five liquid-cooled electrical boxes 22, thereby completing the entire main circuit.

[0054] To sum up, the liquid-cooled energy storage integrated cabinet of the present invention has an inner cavity designed with independent battery compartments, cooling unit compartments and equipment compartments. The battery compartment is used to install the main control box and the liquid-cooled electric box, the cooling unit compartment is used to store the liquid-cooled unit, and the equipment compartment is used to arrange the AC distribution module and PCS. The external mains electricity passes through the AC distribution module, PCS and main control box in sequence, and then connects to two or more liquid-cooled electric boxes to realize the entire main circuit. The liquid cooling unit is connected to each liquid-cooled electric box through a pipeline, so as to realize temperature control of the liquid-cooled electric box. Each module can be assembled independently, and then the independent modules can be connected by wiring harnesses and connectors. It can be flexibly selected according to customer needs to adapt to various scenario requirements.
