After retrieval, the Chinese utility model patent with the patent application number CN202322139052.4 discloses a liquid-cooled energy storage outdoor cabinet based on sound wave vibration detection, which is an energy storage cabinet in the form of liquid cooling. Using the integrated design concept, each component is closely matched. However, it adopts the form of double doors, the cabinet body is relatively wide, and the occupied space is large. If the space is narrow, it is not conducive to the installation and use of the equipment; and if a certain component has a problem and needs to disassemble the cabinet, the component cannot be disassembled, repaired or replaced separately, and the later maintenance is relatively troublesome. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a liquid-cooled energy storage cabinet in view of the above-mentioned defects of the prior art. The liquid-cooled energy storage cabinet adopts the form of a single door, concentrates the internal devices on one side, and with the optimized design of each bin, each component forms a unique space separately, ensuring the full utilization of each space and being relatively convenient for later maintenance.

[0004] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0005] A liquid-cooled energy storage cabinet includes a cabinet body. Inside the cabinet body, a liquid-cooled bin, a battery bin and a high-voltage bin are arranged in sequence from top to bottom. A liquid-cooling machine and a liquid-cooling pipeline connected to the liquid-cooling machine are arranged in the liquid-cooled bin. A plurality of battery packs are arranged in the battery bin. A PCS module and a high-voltage box are arranged in the high-voltage bin. A front door is arranged at the front end of the cabinet body, and a battery heat preservation board and a BMS module corresponding to the battery pack and the high-voltage box respectively are arranged on the front door.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further describes the specific embodiments of the present utility model in conjunction with the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0018] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0019] As Figures 1-3 shown, the liquid-cooled energy storage cabinet includes a cabinet body. Inside the cabinet body, a liquid-cooled chamber 1, a battery chamber 2, and a high-voltage chamber 3 are sequentially arranged from top to bottom. A liquid chiller 1-1 and a liquid-cooling pipeline 7 connected to the liquid chiller 1-1 are arranged in the liquid-cooled chamber 1. A plurality of battery packs 2-1 are arranged in the battery chamber 2. A PCS module 3-1 and a high-voltage box 3-2 are arranged in the high-voltage chamber 3. A front door 4 is arranged at the front end of the cabinet body. A battery thermal insulation board 4-2 and a BMS module 6 corresponding to the battery packs 2-1 and the high-voltage box 3-2 respectively are arranged on the front door 4. It can be understood that compared with the traditional energy storage cabinet, the present utility model directly adopts the form of a single-opening door, and all electrical components, etc. are concentrated on one side. Coupled with the optimized design of the cabin, the full utilization of each space is ensured.

[0020] Specifically, the left side of the front door 4 is connected to one side of the cabinet body through a hinge, and the right side of the front door 4 is connected to the other side of the cabinet body through a lock 5; several equally spaced battery pack pallets are arranged in the battery compartment 2, and the battery pack 2-1 is installed on the battery pack pallet; several heat dissipation ventilation holes 4-1 corresponding to the liquid cooling compartment 1 are opened on the front door 4; several lifting rings 8 are arranged at the upper end of the cabinet body, and the lifting rings 8 are arranged in sequence at the vertices of a rectangle; several indicator lights 9, antennas 10 and emergency stop buttons 11 are installed at the front end of the front door 4, and the indicator lights 9, antennas 10 and emergency stop buttons 11 are all electrically connected to the BMS module 6. It can be understood that a general liquid cooler is used for the liquid cooler, and the heat dissipation of the chassis is carried out through liquid cooling. The battery compartment is a separate compartment to ensure the heat preservation of the battery pack; a fan can be built in the high-voltage compartment to facilitate the heat dissipation of this compartment, and the high-voltage box is located at the bottom side, which is convenient for the cables at the bottom to shorten the connection journey, facilitate installation, and manage the wires in the energy storage cabinet; the lock is used to lock and fix the front door; the lifting ring is used for the lifting of the equipment; the indicator lights are red, yellow and blue indicator lights.

[0021] It can be understood that the design of the present utility model is reasonable and the structure is unique. The present utility model integrates all devices on one side, making full use of the space of the entire cabinet. The liquid cooling pipeline runs inside the cabinet. There is an overall single door, with the width reduced and the floor space decreased. The single-opening door can save space and is also convenient for installation and maintenance, being clear at a glance. The high-voltage box is placed at the bottom of the entire cabinet to shorten the connection path of cables, etc., facilitating installation. It is divided into three compartments in total. The first compartment is for liquid cooling, the second battery compartment is sealed for heat preservation, and a small fan can be added inside the third compartment for internal circulation to maintain a dry environment. Different compartments have different functions. The key point is the space layout of the entire cabinet. Each part forms its own unique space separately. The liquid cooling compartment, battery compartment, and high-voltage compartment are separated. If there is a problem with each component, it can be disassembled, repaired or replaced separately without disassembling the cabinet. The structural layout of the liquid cooling pipe makes full use of the width space, making the width of the energy storage cabinet reach the extreme.

[0022] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present utility model.
