[0002] Energy storage cabinets are special equipment used in distributed power generation systems for energy storage, temporary power supply for important equipment, etc. They are mainly composed of several energy storage modules and monitoring devices. Since energy storage modules and charging and discharging units will generate a lot of heat during the charging and discharging process, in order to ensure that the equipment in the energy storage module can operate normally within the appropriate temperature range and prevent overheating, its heat dissipation structure needs to be designed accordingly. The current solution is mainly based on the existing heat dissipation and ventilation structure design of the power distribution cabinet. Since open heat dissipation and ventilation structures are mostly used, there are many kinds of flying dust and floating foreign objects. Due to the continuous static electricity during the power storage process and the electric field of the components in the structure, various impurities are easily adsorbed on the inner wall of the power storage module and the energy storage cabinet, which makes it difficult to clean and maintain after a long time, affecting the use of the equipment.

[0028] The present invention is described in detail below in conjunction with specific embodiments.

[0029] The present invention relates to an energy storage cabinet, which is mainly used as an installation and maintenance device for energy storage modules in various types of battery energy storage systems and backup electric energy storage systems. It provides a more efficient and stable heat dissipation structure, and provides a fully enclosed internal circulation heat dissipation and a semi-enclosed internal and external circulation heat dissipation solution that can be quickly switched. In order to meet the different working modes of the energy storage cabinet and the use in different heat dissipation demand scenarios, the structural design of the heat dissipation system of the energy storage cabinet is simplified.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, its main structure includes a cabinet 1, a support and heat dissipation frame 2, a wind control component 3, an air inlet and outlet component 4, and a power storage module 5;

[0031] The cabinet 1 is a hollow shell structure with an opening and closing door on the front side;

[0032] like Figure 4 , Figure 5 As shown, the support heat dissipation frame 2 includes a rectangular air inlet and outlet duct 20 located in the middle, and the air inlet and outlet duct 20 is divided into front and rear air inlet ducts and air outlet ducts by a vertical air partition plate 21 in the middle;

[0033] A plurality of hollow support plate frames 22 are provided on the left and right sides of the air inlet and outlet ducts 20, and a vertical partition plate 23 is provided in the cavity of the support plate frame 22; one end of the vertical partition plate 23 is connected to the vertical wind partition plate 21, and the other end forms an air passage 20a with the inner cavity arm of the support plate frame 22; an air guide hole 20b is provided on the outer side of the support plate frame 22, and the air guide hole 20b passes downward through each air passage 20a, and the aperture of the air guide hole 20b is consistent with the width of the air passage 20a;

[0034] like Figure 6 As shown, the wind control assembly 3 includes two wind guide pipes 30 inserted from top to bottom into the wind guide holes 20b on the support plate frames 22 on both sides, and a control rod 31 located in the wind guide pipe 30, and a linear drive device 32 for controlling the up and down movement of the control rod 31;

[0035] The front and rear sides of the air guide 30 and the corresponding positions of the inner cavity of each support plate frame 22 are provided with air holes 30a, and overflow holes 30b are provided between adjacent air holes 30a;

[0036] The control rod 31 can be inserted into the air guide tube 30 movably up and down, and the control rod 31 is provided with an air guide structure directly facing each air hole 30a, and the air guide structure includes a wind shield plate 31a which can respectively block the inner cavity of the air guide tube 30 on the upper and lower sides of the air hole 30a;

[0037] The linear drive device 32 is used to drive the control rod to move up and down, so that the air guide structure moves to the upper side of the corresponding air hole 30a or to a position at the same height;

[0038] The air inlet and outlet assembly 4 includes an air inlet pipe and an air outlet pipe respectively connected to the air inlet pipe and the air outlet pipe;

[0039] The power storage module 5 includes a plurality of battery packs 50 disposed between the support plate frames 22 .

[0040] Based on the above structural design, a closed refrigeration cycle closed channel is formed by using the support heat dissipation frame 2, and the energy storage module is arranged between the support plate frame 22 to absorb the heat generated during the operation of the energy storage module;

[0041] By controlling the up and down movement of the control rod 31, the closed refrigeration cycle channel can be connected or disconnected with the inner cavity of the shell to realize a separate closed internal circulation heat dissipation, or the low-temperature medium can enter the inner cavity of the shell through the overflow hole 30b for external refrigeration. By switching the movement distance of the control rod, the ratio of the internal and external circulation air volume in different modes can be adjusted, so that the heat can be dissipated more flexibly and quickly as needed. The device has a simple structure, is easy to control, and is more convenient to maintain and use than traditional energy storage cabinets.

[0042] Furthermore, in order to prevent dust from accumulating inside the pipe after long-term use and affecting the internal heat dissipation performance, in this embodiment, a dust collecting port 9c is provided at the front or rear side of the bottom of the air inlet pipe and the air outlet pipe;

[0043] The bottom of the air inlet duct and the air outlet duct are respectively provided with a dust collecting box 6, which can be inserted or removed from the dust collecting port. The dust collecting box 6 can be used to regularly clean the dust accumulated in the internal pipeline to ensure the cleanliness of the interior of the channel.

[0044] During actual use, the energy storage modules used simultaneously are usually of the same model. As a preferred implementation scheme, in order to facilitate the arrangement of the energy storage modules, the support plate frames 22 in the present application are symmetrically arranged on the left and right sides of the inlet and outlet air ducts 20, and are arranged in an array with equal spacing along the vertical direction.

[0045] In the further implementation process, different support plate frame spacings can be configured as needed to meet the installation and fixation of energy storage modules of different sizes, but at the same time, the positions of the air holes and the air overflow holes need to be adjusted accordingly.

[0046] To ensure the effectiveness of the refrigeration circulation channel, the left and right widths of the battery pack 50 should be smaller than the width of the vertical partition plate 23, and the front and rear widths of the battery pack 50 should be smaller than the width of the inner cavity of the cabinet 1; the front and rear left and right parts of the support plate frame 22 that exceed the battery pack 50 and the inner wall of the cabinet 1 form an outer circulation cavity 9a, and the shell wall of the cabinet 1 is provided with a ventilation hole 9b that is connected to the outer circulation cavity. By controlling the width of the battery pack 50 and the shell and the front and rear left and right sides of the support plate frame 22, it is ensured that the circulation loop has sufficient air inlet and outlet efficiency and that the heat can be taken away in time.

[0047] In order to provide a more flexible circulation control method, the present application also provides an improved wind guide control scheme, wherein a flap 31b is connected to the upper and lower wind shields 31a in the wind guide structure; the flap 31b is vertically arranged and divides the wind shield 31a into two parts, front and rear, and the front and rear parts are provided with diversion holes 31c, and also includes a rotation drive device for controlling the rotation of the control rod 31.

[0048] Based on the above structure, the rotating structure can be used in conjunction with the flap and the diversion hole 31c to control the flow ratio of the heat dissipation gas in the internal and external circulation loops without adjusting the up and down position of the control lever, providing a more flexible and efficient control method. It should be noted that under this scheme, the overall heat dissipation cycle is semi-closed.

[0049] In particular, in order to improve the heat dissipation efficiency and the heat extraction efficiency in the energy storage module, the support plate frame 22 in the present application is made of a heat-conducting metal material.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
